Due to its ability to manipulate mana freely, the Mana Spar threw enough fireballs to cover more than twenty square meters of ground.

In other words, when the number of mana firethrowers reaches a certain level, even if thousands of troops rush in, I am afraid that they will have to suffer great losses before they can rush in front of these magic firethrowers and kill them.

Magic fire throwers are the essence of the hell class, a sufficient number of magic fire throwers can exert a strong power against several times the number of troops, in short, these enough magic fire throwers are a group of cannons, when the power is released, the enemy is afraid of the enemy.

That's right, this kind of area attack can easily be accidentally damaged, and if you have someone in the fireball bombardment range, then ask for more blessings.

Seeing that group of magic fire throwers, Cheng Kong couldn't help but feel a little lucky, if he brought a group of subordinates over, I was afraid that the loss would be unimaginable.

However, what gave Cheng Kong the most headache was that behind that group of magic power fire throwers, there were three crypt demons holding flame whips.

This sulfur mine is really an easy and difficult position to attack, with ordinary demons in melee combat, mana fire throwers in distant attacks, and a crypt demon array that can summon ordinary demons from corpses.

Even if the giant mantis wants to attack this sulfur mine unscathed, it will be a little difficult.

Let's try the fire first, Cheng Kong's right hand opened, and a series of magical brilliance began to flicker on his body, echoing the magical brilliance brought by the three kinds of magic of shield, blessing, and stone skin.

The magic of the shield formed a transparent wall of qi outside Cheng Kong's body, and Cheng Kong touched it with his fingers. Basically, the defense is about the same as the turtle shield, or even stronger.

The blessing technique flashed a silvery-white light on Cheng Kong's body, and then shrunk into his body. made Cheng Kong feel that he had more control over his body.

The skin of the stone is forming an earthy yellow film outside Chengkong's body, which is tough and elastic.

After the most rear, Cheng Kong activated the turtle shield, and another layer of qi wall covered the outside of the body, after preparing for all this, Cheng Kong took the big bow from his back, took aim, and took a magic fire thrower with an arrow.

In an instant, a magical fire thrower fell under Cheng Kong's arrows.

As the mana firethrower fell. The whole sulphur mine is like a hornet's nest that has been stabbed, all the magic fire throwers, ordinary demons. Even the three crypt demons all looked towards Cheng Kong.

The magic fire throwers rubbed their hands together, and orange fireballs the size of a human head immediately formed between their hands, and then these fireballs flew towards Cheng Kong.

More than a hundred fireballs flew like a meteor shower, and the position where Cheng Kong was standing was just covered by those fireballs.

Cheng Kong was not interested in using his own body to test the power of those fireballs. Turn around and run.

Boom, boom, boom. The fireball exploded into a sea of fire behind Cheng Kong, and the explosion of the fireball formed a shock wave that blew out in all directions, Cheng Kong felt as if he had been punched in the back, and his body that was fleeing was like a baseball smashed out of the air, and hit the stone wall with a bang.

However, the damage caused by this impact is really nothing to Cheng Kong.

With a click, Cheng Kong fell to the ground without even looking back. Keep running for your life.

After escaping into the passage, Cheng Kong turned his head to check.

Those fire throwers. The demon seemed to be restrained, and after chasing for some distance, he turned back to the brimstone mines.

It seems that this trick is feasible, Cheng Kong smiled, touched his back, and was not injured, but it was a little red and swollen, the only problem was that the two layers of qi walls generated by the turtle shield and the shield were shattered in the violent impact.

After all, at the same time as the fireball exploded, the ground was shattered and the rubble that came out of it had a huge kinetic energy, Cheng Kong was still quite strong, and if he were an ordinary person on the earth, he would have been directly stoned to death by the flying gravel.

After those fire throwers and demons returned to the sulfur mine, Cheng Kong activated the turtle shield and shield again and released it, and then quietly lurked over.

Well, to be honest, Cheng Kong's so-called quiet lurking is just lying on the ground and crawling forward.

It's a pity that under the light of the volcanic flames and even the fluorescent moss at the top of the hall, the entire hall is basically brighter, besides, those fire throwers, demons were originally creatures that grew in the underground passages, even if the light was dim, their vision was enough to find Cheng Kong's location.

Therefore, before Cheng Kong could climb to a position where he had enough range, those fire throwers moved and rushed towards Cheng Kong.

Cheng Kong saw the movement of those fire throwers, and he didn't dare to play any suspicious tricks, jumped up from the ground, and rushed towards the fire throwers.

When he was in range, he shot an arrow, then turned and fled, escaped some distance, saw that the fire throwers were not fast, turned around and ran again, and then ran straight away.

No way, after the fire thrower chased it out, those demons and crypt demons also chased it out, and its speed was much faster than that of the fire thrower.

If you are entangled by these guys, I am afraid that even if you send the giant mantis out, you will not be able to escape the baptism of the fireball of the fire monster.

After these firethrowers evolved into magical firethrowers, their range was far beyond that of ordinary archers, reaching a range of about 100 meters, and the fireballs they threw were still area damage, which invisibly increased the range a little.

In this way, if Cheng Kong is not paying attention to it, he will be covered by the fireball thrown by the fire thrower.

After escaping back to the passage this time, the fire throwers seemed to be very angry at Cheng Kong's provocation, so they chased them into the passage for some distance.

Helplessly, Cheng Kong escaped a little too fast, and they didn't have the ability to teleport like the Qian Hall Master, so they had to return to the sulfur mine regrettably.

Two times in a row, Cheng Kong killed three magic fire throwers, but the dead bodies of these magic fire throwers were carried back by ordinary demons and piled up next to the sulfur mine.

Strangely, after the three Crypt Demons swung their flaming whips and struck the corpses a few times, it was said that the corpses of the three Magical Fire Splitters should have turned into Evolved Light Balls. But it didn't move at all, and the corpse didn't move at all.

In this regard, Cheng Kong has no regrets. After all, the Magic Fire Thrower is still a second-level class, and the evolved light ball turned into is of little use to himself, but it is an ordinary demon following the Magic Fire Thrower, and the Crypt Demon is more valuable to Cheng Kong.

Take your time, Cheng Kong looked at the number of magic fire throwers that had barely decreased, and once again rushed towards the hall.

Since, it is impossible to fool these guys. Then let's fight head-on, maybe we can kill a few more.

Sniper crossbow excitation!

Cheng Kong pulled out the big bow, and a pale yellow glow appeared on the arrow. With a slight release of his right hand, the arrow dragged out a faint yellow light in mid-air, and after spanning hundreds of meters, it plunged headlong into the chest of a magical fire thrower. Pierced through the chamber.

The arrow pierced into a snowdrift like a red-hot steel chisel. In one go, all the seven mana fire throwers lined up in a line pierced through the chamber.

The sniper crossbow was really useful, Cheng Kong couldn't help but be overjoyed, and once again opened his bow and shot an arrow.

However, this arrow was not as powerful as the previous one, and it only killed a magical fire thrower.

The effectiveness of the sniper crossbow activation is limited to one arrow, and it will take a little time to activate it again, which is similar to the spider silk arrow. However, the recovery time of the Spider Arrow is much faster than that of the Sniper Crossbow.

After the second arrow was fired, Cheng Kong fled again. Followed by a large group of fire throwers and even ordinary demons and crypt demons, this time, the range of the fire throwers extended a few hundred meters compared to before, chasing them in the underground passage for nearly two miles, before they returned in a hurry.

In this way, Cheng Kong kills again and again, escapes, returns, kills, escapes, returns.

Although the range of those fire throwers is getting wider and wider, their numbers are getting smaller and smaller.

But what made Cheng Kong a little big was that when the corpse pile next to the sulfur mine accumulated to a certain extent, the crypt demons began to wield the flame whip and dance a strange dance.

The corpses began to burst one by one, and blood splattered out, forming a huge blood cocoon, and after a while, the blood cocoon burst on its own, and ordinary demons crawled out of it.

After a dozen or so times, the last fire-throwing monster fell to the ground wailing under the arrow, but the number of ordinary demons quickly increased to more than seventy.

At this time, those ordinary demons were also chasing wildly to a hundred meters away from Chengkong.

The giant mantis strikes! After destroying the long-range troops, the giant mantis suddenly jumped out, instantly expanding from the size of its finger to more than twenty meters, and the turquoise knife arm popped out, forming a series of knife lights that could not be seen by the naked eye, rushing to the bodies of several ordinary demons in the front for a moment, and then splitting apart, the blood in the body erupted, and the body fragments splattered everywhere.

In an instant, the giant mantis rushed into the ordinary demon group and set off a bloody rain.

In the face of the giant mantis's rapid attack and blade dance, ordinary demons who were caught in the attack range by the giant mantis's knife arm could only dodge in vain, and then were cut to pieces by the knife arm.

Just after more than a dozen ordinary demons were reduced to pieces, the three-headed crypt demons finally arrived, and the flaming flame whip drew several lines of fire in mid-air and landed directly on the giant mantis.

As a fifth-level class, the Crypt Demons do not have the same great strength as the Minotaurs, but the flame whip in their hands has a special effect, after the whip hits the giant mantis, then a line of fire is formed in the place where the giant mantis is struck, and then quickly extends, binding the body of the giant mantis, and the line of fire burns the body of the giant mantis to a creak.

After the giant mantis was restrained by the line of fire, those ordinary demons immediately pounced on the giant mantis like mad dogs, and sharp claws popped out of their palms, launching a crazy attack towards the giant mantis.

Even though the giant mantis's body was covered with incomparably hard hard armor, under the frantic attacks of dozens of ordinary demons, that layer of hard armor began to appear scratches continuously, and even wounds appeared, oozing dark green liquid.

This is the second time Cheng Kong has seen the giant mantis get hurt, and in the previous battles, except for the time when he was injured in the battle with several minotaurs, even this time.

The flames produced by the flame whip seemed to have a special damage effect on the giant mantis, and the giant mantis felt extremely painful from the psychic link to Cheng Kong.

"Curses!" Cheng Kong's right hand pointed at a crypt demon, and then a fiery red light appeared on the crypt demon.

As this fiery red light appeared, a line of fire on the giant mantis's body immediately dimmed, and the damage to the giant mantis was also reduced.

"Curses. Curse! Cheng Kong saw that the curse technique was really effective, so he naturally would not slack off, and released two curse spells again in one go. Reduces the damage of the remaining two Crypt Demons to a minimum.

"Healing! Blessing! Stone skin! Shields! Then Cheng Kong pointed at the giant mantis again, and released the auxiliary spells one by one on the giant mantis.

After releasing these spells, Cheng Kong immediately felt an emptiness in his mind, and a feeling of dizziness poured into his mind, causing Cheng Kong to sit directly on the ground almost with his ass.

This was a sign that his mental power was drained, and Cheng Kong sat on the ground and rested for a few seconds before the dizziness receded from his mind. Although it has returned to normal, it is impossible to cast the spell.

At this point, Cheng Kong couldn't help but feel a layer of sweat on his back.

Fortunately, there is a giant mantis in front. If you come to this in the middle of a battle, hum, let alone being surrounded by a few ordinary demons, even if it is a group of spearmen. Wait until the reply comes. I'm afraid Cheng Kong is also full of holes.

It seems that the number of spells released will be controlled in the future, Cheng Kongxin is secretly afraid, and he will never dare to be so reckless again.

As the magical brilliance of healing, blessing, stone skin, shield, and other spells bloomed on the giant mantis's body, the giant mantis, which had been scarred by the line of fire, suddenly burst out with a huge force, and the blade flurry was used again. The ordinary demons who had been surrounding the giant mantis immediately suffered a great disaster.

Suddenly, red lines appeared on the crimson tough skin of ordinary demons. Then, under the pressure of the blood spurting from the heart, the body of the ordinary demon split apart along with the red threads, and exploded into a cloud of fiery red blood mist.

A cloud of blood mist shrouded the giant mantis, but this did not affect the strength of the giant mantis, and the knife arm swung again, and the ordinary demon exploded into a blood mist, filling the underground passage almost impossible to see.

The three-headed crypt demon desperately swung the flame whip, trying to restrain the giant mantis again, but at this moment, Cheng Kong, who had recovered, shot an arrow, and the spider web emerged from the ground, firmly sticking a crypt demon to the ground.

Taking advantage of the fact that the other party was sticky, the giant mantis cooperated very well, and with a flash of the knife, several blood marks immediately appeared in front of the crypt demon's chest, but because the giant mantis fought for a while, these knives were not able to directly cut the crypt demon into pieces, but under the attack of these knives, the crypt demon only had its spine connected, and the rest of the parts were broken, spurting hot and corrosive blood.

This blood sprayed on the giant mantis's body, and even the giant mantis's smooth and dust-free hard armor kept bursting out of strings of bubbles.

Grass, the blood of this crypt demon can be compared to aqua regia.

Cheng Kong scolded secretly, and shot an arrow again, hitting the right arm of the other Crypt Demon holding the flame whip, and the sharp arrow instantly pierced the Crypt Demon's right arm, but for the fifth-level Crypt Demon, such damage can be recovered in a short time.

"Die!" Cheng Kong immediately used the Phantom Scepter, and five illusions of Cheng Kong immediately appeared a few meters around Cheng Kong.

As soon as the five illusions appeared, they drew their bows and arrows, and a moment later, five arrows flew out and plunged into the bodies of the two Crypt Demons.

Attacked by continuous arrows, the attention of the two crypt demons was attracted by Cheng Kong and rushed towards Cheng Kong.

Cheng Kong naturally wouldn't stand in place and wait for the other party to kill, turn around and flee, of course, if you spread your wings and run away, the speed will be faster, but the problem is that the height of this section of the underground passage is not enough, if Cheng Kong flies up, it is not only easy to hit the wall, but also easier to be hit down by the flame whip of the crypt demon.

It was an attack that could hurt the giant mantis, and Cheng Kong really didn't have the idea of trying it.

Next, it's time to fly a kite.

Cheng Kong and the five illusions formed a large circle together, constantly moving and shooting arrows, and the two crypt demons sometimes pursued the illusions, sometimes chasing Cheng Kong, greatly slowing down the time to catch up with Cheng Kong.

But even so, Cheng Kong gradually fell into danger.

The five illusions were a little too fragile, and if they didn't pay attention, they hit their heads against the stone wall and turned into a cloud of starlight and dissipated into the air.

After escaping for hundreds of meters, only two of the five illusions remained, and the distance between the Crypt Demon and Cheng Kong was getting closer and closer.

Once Cheng Kong is caught up by these two crypt demons, I am afraid that he will die more and live less.

No matter how powerful Cheng Kong is, he will face two fifth-level troops at once. It is also a situation where there is no life and death.

Just when Cheng Kong was in danger, the giant mantis had already completely killed the crypt demon, and freed up its knife arm to start dealing with those ordinary demons who kept attacking him like mad dogs.

Finally. The last phantom was chased and killed by the Crypt Demon, and Cheng Kong fell into the danger of being pursued by the two Crypt Demons.

The distance between the two sides has been shortened to less than twenty meters, and at this distance, the Crypt Demon may swing a flame whip to trap Cheng Kong at any time, and then it will be time for Cheng Kong to die.

Cheng Kong was probably able to carry three or four attacks at most, and after three or four attacks, Cheng Kong estimated that he was about to turn into a piece of charcoal or meat paste.

Can't. The difference in strength is a little bigger, and Cheng Kong's flesh that can resist the attacks of the second and third level troops is a joke in front of the Crypt Demon.

Hmph, the flame whip turned into a flame and drew towards Cheng Kong. forced Cheng Kong to retreat sharply, while the other crypt demon outflanked Cheng Kong, so Cheng Kong really fell into a desperate situation.

A cruel smile appeared on the Crypt Demon's face. This little flea can't escape!

Just when the two Crypt Demons will swing their flaming whips at the same time. A green shadow quickly chased after it from behind, and with a flash of swords, a crypt demon suddenly let out a howl of pain, and a long knife mark emerged from its back, almost slashing it in half from its right shoulder.

The giant mantis finally killed the remaining ordinary demons, and after discovering that Cheng Kong was in danger, the giant mantis chased after him despite his serious injuries. A knife solved Cheng Kong's desperate death situation.

But even so, Cheng Kong was whipped by the remaining crypt demon. Restrained in place, a line of fire immediately appeared on Cheng Kong's body and began to burn violently.

Compared to the intense pain of the giant mantis when it was attacked by the flame whip, Cheng Kong seemed to be more resistant to the damage caused by this flame whip, and the crypt demon at this time had been reduced to a minimum by the curse spell, if the two crypt demons shot at the same time, Cheng Kong would have to be seriously injured.

But the attack of a crypt demon, although Cheng Kong was not lightly injured, but Cheng Kong was able to resist after all.

As the giant mantis slashed out again, slashing the crypt demon to the point where it couldn't afford to be seriously injured, the line of fire that had originally bound Cheng Kong immediately dissipated.

As for Cheng Kong, the two cave demons in front of him who were seriously injured and dying, naturally wanted to take revenge and revenge, and taking advantage of his illness to take his life was the right way.

Cheng Kong struggled to pull out the big bow and shot several arrows at the head of the crypt demon.

As the arrows continued to pass through the heads of the Crypt Demons, these Crypt Demons, no matter how strong their physical recovery ability was, could not survive any longer.

With the end of the battle, Cheng Kong suddenly felt a sense of emptiness all over his body, and he couldn't support it anymore, and he fell to the ground, unable to get up.

The soreness caused by the overload of the whole body was released at the same time, so that Cheng Kong couldn't even move a little finger.

Cheng Kong is now sad, and the giant mantis is similar to him, two of the four hind feet are broken, and the originally smooth hard armor is full of cracks, and dark green body fluids are constantly leaching out.

The giant mantis was also lying on the ground at this time, except for the tentacles on the top of its head shaking, and it looked like it was dying.

After more than ten seconds, the corpse on the ground began to decompose into a large number of evolutionary light balls, flying towards Cheng Kong and the giant mantis respectively.

As the evolutionary light ball continued to integrate into his body, the sequelae caused by Cheng Kong's previous fierce battle were swept away, and the evolutionary power in his body went from a latent state to a boil.

Although the giant mantis contributed the most in this battle, the number of evolution light balls that Cheng Kong shared was also quite a lot, and Cheng Kong had a hunch that if he was willing now, he could barely evolve again, of course, if that was the case, it would not be beneficial to Cheng Kong's future development.

As the power of evolution gradually subsided from the boiling, Cheng Kong suppressed the slightest urge to evolve.

Let's think about evolution in the next battle.

Cheng Kong stood up from the ground and looked at the giant mantis.

At this time, the whole body of the giant mantis was constantly recovering, and all the injuries were quickly eliminated under the effect of evolutionary power, and the bright green color appeared again.

After recovering from its injuries, the giant mantis jumped towards Cheng Kong, its body quickly shrunk, and when it reached the size of its fingers, it threw itself on the top of Cheng Kong's head and lay down, unwilling to move again.

Sulphur mines are just around the corner!

Cheng Kong ran towards the sulfur mine after the giant mantis was ready.

Of course, when Cheng Kong received the sulfur ore. It's not all smooth sailing, and those little devils who mine are also fighting back.

Well, Cheng Kong brutally suppressed the rebels. All the broken limbs were piled up together to form a mountain of meat.

After thoroughly cleaning up the amount of resistance, Cheng Kong took out more than a dozen golden beetles from the space bag and placed them on Roshan.

Under the desperate gaze of those little devils, the golden beetles began their feast.

Although the blood of these little devils is slightly corrosive, for a magical creature like the golden beetle, the flesh of the little devil is not bad, and it can still be eaten. At least it's much stronger than a stone without moisture.

You must know that these gold beetles have to swallow a large amount of gold ore every day when they are mining gold.

As Roshan continues to cut down, the number of golden beetles increases. When the little devils who made up Roshan were eaten up even the bones, the number of golden beetles was close to 150,000 or 60,000.

After collecting more than a dozen pieces of sulfur piled up next to the stone trough, Cheng Kong began to drive the gold beetle to refine the sulfur.

The initial losses were extremely heavy, after swarms of gold beetles that could be eaten by stones poured into the magma gushing out of the crater. The heat of the magma quickly burned the gold beetle to ashes.

Cheng Kong almost thought that these gold beetles would not be able to refine sulfur at all.

Available over time. These gold beetles also began to adapt to the high temperature of the magma, initially with a maximum of one gold beetle out of a hundred, but later, most of them were able to survive twenty or thirty gold beetles out of a hundred.

There is no doubt that the golden beetle, a magical creature, began to adapt rapidly to this volcanic environment, or should it be said to have evolved rapidly, for a reason that Cheng Kong could not understand.

Of course, this evolution has nothing to do with the improvement of combat effectiveness, and Cheng Kong took advantage of the opportunity of the golden beetle to continue pouring into the magma to die. He did a test and spat on a golden beetle that had survived the lava.

Just a mouthful of spit. When the spit fell on the golden beetle, the golden beetle collapsed after a struggle.

There is no doubt that there is a limit to this evolution, and since they are not afraid of high temperatures, water or ice is fatal to them.

Come to think of it, if you are not afraid of high temperatures, water, and ice, this golden beetle is simply a perverted creature.

Of the 150,000 or 60,000 golden beetles that reproduced, less than 30,000 survived in the magma.

However, this number of gold beetles is enough for the time being.

The surviving golden beetles were initially half-dead in the lava, and it took a long time to even move, but gradually, the golden beetles began to become active and burrowed into the magma.

When the first gold beetle crawled to the stone trough container and pulled out a bean-sized sulfur, Cheng Kongzhi said that the sulfur mine resumed production from this moment.

Of course, it takes a lot of time for the first piece of sulfur to be produced, and Cheng Kong can't waste time waiting, and then he walks towards the underground passage behind the sulfur mine, in addition to exploring the situation of the passage behind, Cheng Kong is also ready to clean up the wild things along the way, so as to ensure the safety of the sulfur mine.

Cheng Kong walked for more than two hours, and found three golden treasure chests along the way.

The guardians of the golden treasure chest are just some fire throwers and little devils, and even the giant mantis doesn't need to be dispatched, Cheng Kong can easily get rid of them alone.

However, after occupying the sulfur mine, Cheng Kong felt that his luck seemed to have deteriorated.

This three golden treasure chests in a row, not to mention the treasures opened, even the number of gold coins obtained has hit a record low.

A golden chest is 1,100 gold coins, a golden chest is 1,000 gold coins, and the last golden chest is 500 gold coins.

It was indeed an all-time low, and the gold from the three chests was about the same as a day's income from the farm.

Of course, the farm has now been sold to the Xiangjiang forensic doctor.

Cheng Kong shook the money bag and continued to move forward.

After advancing fifteen miles, Cheng Kong found a problem.

This road is not working!

Actually, it's not that it's not really impossible, it's that there's a creature nest in front of the underground passage.

If an ordinary biological nest is in front of him, Cheng Kong will directly bulldoze the past, and occupy a biological nest by the way, why not.

But the creature lair was a crater, and from a distance, some fiery humanoids were playing in the lava in the crater.

Kindness. Those flame humanoids seemed harmless from a distance, but they made Cheng Kong secretly gasp.

These flame humanoids are not honest masters, they are the sixth-level fire demons of the hell system!

They are said to be a demonic creature formed by evil condensing in magma. Fiery red smooth skin, long horns, and flowing magma in the veins.

All of this is a symbol of evil.

On top of that, the innate flame aura outside of their bodies will let the enemy know what the hell of fire is, as long as the enemy is within five meters of the fire demon, they will be scorched by the fire aura, and when the enemy attacks the fire demon in close range. Any damage dealt to Firefiend will be partially converted into fire and reflected to the attacker.

This innate ability to fire gives the Flame Demon a huge advantage in melee combat with enemies, and with its innate recovery ability, even a giant mantis cannot be killed in a short period of time.

What's more, the number of these evil creatures frolicking in the crater magma alone is more than twelve.

Such a number of fire demons gathered together. Even a city would not dare to attack it easily.

As for Cheng Kong, it's better to take a look and leave.

Cheng Kong was a lot more relieved, even if there were other cities or powerful creatures in the passage behind the fire demon's lair, it would be impossible for them to pass through here in a short time.

Besides, these fire demons are the guardians of the lair. As long as no one in their own direction provokes them. They don't leave their nests easily.

After returning to the sulfur mine, Cheng Kong looked at the sulfur particles in the stone trough, it was still early to fill the entire stone trough to form a whole piece of sulfur, and according to this trend, it would take about five or six hours to fill it.

The location of the sulfur mine is relatively safe, and Cheng Kong doesn't have to worry too much, the forty or fifty-mile-long underground passage will make many impatient guys return halfway.

When Cheng Kong returned to the Colorful Fountain, the old horse was still lying in the Colorful Fountain.

I saw Cheng Kong come back. The old horse was a little excited: "I opened a hole." ”

For the excitement of the old horse, Cheng Kong smiled a little bitterly. Perhaps because of his age, the benefits that Lao Ma enjoyed in the colorful fountain were far worse than his own.

At this rate, I'm afraid that the remaining days of the old horse will be spent in this colorful fountain.

If you can't open up a meridian, after a few days have passed, the acupuncture points you have opened will shrink over time, and your previous efforts will be lost.

As soon as Cheng Kong said this, Lao Ma was a little hesitant, in this case, if he wanted to rush back to Black Crow City, he could only wait for the next time he entered the Hero World Realm.

This will take some time, but in Cheng Kong's opinion, it is worth spending more time to make Lao Ma stronger.

After deciding this matter, Cheng Kong didn't stay at the Colorful Fountain for long, and turned around and went to the little devil's square last time, where there was also an iron mine, and Cheng Kong felt that it was better to occupy it as soon as possible.

After such a long time, a lot of wild things have appeared in the underground passage between here and Little Devil's Square.

Among them, there are many second- and third-level undead classes such as walking corpses and ghosts, but for the current Cheng Kong, these undead classes can no longer pose a threat to him at all.

Pushing all the way, Cheng Kong easily arrived at Little Devil Square.

Looking at the little devils and demon larvae who were still fighting each other, Cheng Kong felt as if a long time had passed.

Cheng Kong patted the giant mantis lying on his head, and the wings on his back immediately spread out and flew towards the iron mine.

Compared to shooting these little devils one by one with a bow and arrow, which can't be completely eliminated at all, flying directly over is relatively much more time-saving, not to mention that the height of the stone wall here is enough for Cheng Kong to spread his wings and fly high.

When Cheng Kong flapped his wings and came to the sky above the iron mine, more than a dozen fireballs immediately rose from below and smashed towards Cheng Kong.

These fireballs were not much of a threat to Cheng Kong, and Cheng Kong easily dodged them.

Arrows shot out of the bow, killing the fire throwers below.

Compared to the sulfur mine, the guards of this iron mine were too weak, making Cheng Kong a little unmotivated.

As more than a dozen fire-throwing monsters were killed by arrows, the iron ore refinery immediately fell into Cheng Kong's control.

The feed for breeding gold beetles here is much richer than that of sulfur mines, and Cheng Kong can go around and catch more than a dozen little devils or demon larvae casually.

And the painful howl of the golden beetle that caused the little devils to eat almost frightened the little devils who were close to the iron ore refinery.

It took Cheng Kong more than two hours to breed the golden beetle. More than 100,000 golden beetles began to get busy driven by Cheng Kong.

Among them, 50,000 gold beetles were set by Cheng Kong as the guardians of the iron ore refinery, while the remaining gold beetles easily dived into the magma and swallowed the molten iron into their stomachs. Then bring it to the refining site for refining.

These gold beetles are all evolved gold beetles, fully adapted to the magma environment here, and there is no need to worry about excessive losses.

And the iron ore refinery can't be without a guardian, this is the place where the little devils and the demon larvae kill each other, although those little devils are very timid, and the demon larvae have no intelligence, but it is difficult to guarantee that they will not go berserk and attack here.

Once the gold beetles reach a certain number, they will be enough to guard the iron ore refinery. After all, those demon larvae, the strength of the little devil is not strong, and a little devil can only be gnawed into a skeleton when he encounters thousands of golden beetles.

After the iron ore refinery has been straightened out. Cheng Kong put the dozens of pieces of iron essence accumulated by the iron ore refinery into his money bag, and then spread his wings again, rushed into the air, and flew towards the nest of those creatures that produced little devils.

I want to go over from the ground. It's almost impossible. Countless little devils and demon larvae blocked the path of the ground, even if they wanted to kill them, I am afraid that when they reached the halfway point, the little devils killed would not be as many as the little devils who came in.

After Cheng Kong flew to those little devil lairs, Cheng Kong felt that his eyes were a little insufficient.

This is not a few little devil's nests seen before, but hundreds of small devil's nests, densely packed with a small half of the square.

This is no wonder, Cheng Kong was surprised that such a few little devil nests could produce so many little devils in a steady stream. Now that I look at it, I realize that the road is a biological nest, and the number of nests is beyond my imagination.

It also makes sense that hundreds of little devil nests have produced little devils spread over most of the square.

Presumably in the other direction. I'm afraid there will be more of those demon larval nests.

Cheng Kong flew all the way down the magma river, and at the end of the magma river was a huge hollow, and countless magma continued to flow down and disappear into the void.

There is no road in this direction, even if Cheng Kong wants to follow the magma, I am afraid that it will not be long before it will become a piece of coke.

On the contrary, Cheng Kong went up along the magma river and found an underground passage, and after Cheng Kong drilled into this underground passage that was constantly flowing out of magma, it didn't take long for him to fly back.

There is a level in this underground passage, the level is very grand and huge, Cheng Kong glanced at it, there are hundreds of fire throwers stationed in it, a large number of ordinary demons, and even more than 20 crypt demons, a few fire demons.

Cheng Kong was not interested in provoking such a strong defensive force, not to mention that behind a level like this, there was probably a hell city towering.

If you provoke it, maybe even the red dragon will appear, and if that happens, I'm afraid you won't even have a chance to escape.

It seems that this underground passage can be regarded as full of dangers.

There are two underground passages in succession, either there is a fire demon lair at the end of the inside, or there is a pass guard.

After Cheng Kong turned around for a few laps, he didn't have any more interest in exploring, so it was better to go back and soak in the colorful fountain for a while, so as not to be too empty and boring.

When Cheng Kong returned to the Colorful Fountain, Lao Ma opened up another acupoint, Cheng Kong told Lao Ma about the situation of this investigation, and then soaked his whole body in the Colorful Fountain.

Here, there are giant mantis guards as guards, but there is no need to worry about any wild objects popping up while the two of them are sleeping.

The next day, Cheng Kong went straight back to the gold mine, except for putting his long legs in the gold mine to temporarily preside over the gold mine affairs, Cheng Kong led a group of pirate gunners to drag the iron cannon to the direction of the underground passage.

As I said before, the movement speed with the iron cannon is extremely slow, if it weren't for Cheng Kong's efforts from time to time, I'm afraid that even at night, these iron cannons would not be able to drag to the entrance of the underground passage. (To be continued......)
