Evolution, Ma Laosan wants to evolve, but he is not willing to take risks, he would rather deal with those wild things that invade the farm slowly, rather than bet with his life.

In fact, in the past two days, perhaps because of the appearance of the cyclops, some panicked wild creatures have migrated to within twenty miles of the farm.

As long as Ma Laosan is cautious, it is not difficult to deal with these wild things.

After all, those wild things are the strongest and second-level troops, there are no groups, and the largest group is only five or six, so they can't deal with it, and they will guide the other party outside the farm wall, and as soon as the iron cannon sounds, everything is solved.

With Ma Laosan guarding the farm, Cheng Kong is much more relieved.

After all, even the bearded man with the highest IQ will make a lot of mistakes when facing the enemy's attack, and rigidity is a weakness that is difficult for them to remove.

A leader like Ma Laosan can't forge ahead, but he won't make the mistake of making a rash move.

Cheng Kong went to the underground passage this time, and did not bring a single subordinate as usual, after all, in a strange place like the underground passage, if he encounters a strong enemy, he may only bring his subordinates to death in vain, and it is convenient for him to escape by himself.

Back at the deep pit, Cheng Kong did not rush down, carefully observed for a while, and found that no new footprints appeared, so he dragged the rope down and went straight to the colorful fountain.

Perhaps because this place is too remote, the warning trap that Cheng Kong placed near the Colorful Fountain was not touched by the creatures.

Seeing this scene, Cheng Kong was completely relieved and strode into the water of the colorful fountain.

Compared with yesterday's pitch black, the sewage in the colorful fountain has disappeared today.

Cheng Kong took off his clothes. Lying naked in the pool water, a lot of warmth soaked into the body through the skin, making people drowsy.

Cheng Kong first used his internal force to circulate all the acupoint meridians on his right arm several times. Moisturize and nourish the acupoint meridians where you pass.

Although the internal force will also moisturize the nearby acupoint meridians on its own, the effect is much worse than Cheng Kong's conscious guidance.

What's more, lying in the colorful fountain, with the warmth of the spring water penetrating into the body, the gap is getting wider and wider.

After circulating several times in the acupoint meridians on the right arm, the internal force that absorbed a large amount of warmth has expanded and thickened to several times before, and the meridians on the right arm can no longer accommodate this massive amount of internal force. Cheng Kong gently guided, and the internal force like a tide followed the meridians and along the giant bone. Bingfeng, Quyuan and other acupoints rushed towards the Qishe acupoint.

The Qi She point is a slight middle of the base of the clavicle, and Cheng Kong wants to open up the meridians connecting his left arm at this time.

The right arm is after the meridians are opened. Strength skyrocketed. This is a good thing, but the difference in the strength of his arms alone is too large, but Cheng Kong feels very unaccustomed, and even has some inconsistencies in his archery skills.

So much so that the accuracy of archery has dropped significantly.

As an archer, this kind of thing is not something Cheng Kong can endure.

Therefore, it is necessary to open up the meridians and acupoints of the left hand so that the strength of the two hands can be balanced.

Cheng Kong closed his eyes and lay in the pool water, as if enjoying a hot spring. But if you look closely at his face, you will find out. At this time, Cheng Kong was gritting his teeth and enduring incomparable pain.

The internal force is impacting the blocked acupoints and meridians again and again, and it will be broken for a while, and it will come back again.

Thanks to the help of the colorful fountain, Cheng Kong was able to rush to the cave every five minutes, which was hundreds of times faster than those national art masters.

With Cheng Kong's persistence, one by one, one by one, the meridians were opened one by one.

With the smooth passage of the acupoint meridians, the originally transparent and clean pool water was gradually dyed black again.

I don't know how long it took to pass the Dao, the last meridian on the left arm was penetrated by the internal force, and in the blink of an eye, the flow speed of the surging internal force slowed down, and it circulated over and over again along the meridians of the left and right hands.

Compared with the internal strength method taught to Cheng Kong by Murong Xue, Cheng Kong's current internal force flow direction is completely different.

Of course, Cheng Kong's circular way of internal force flow is only able to do it, and others don't even dare to try.

The internal force starts from the tip of the right finger, treats the meridian as a river, flows out of the lun, passes through the right arm, chest, and then flows into the left arm, and then reaches the tip of the left finger, and then flows through another meridian to the tip of the right finger, and so on, forming a somewhat weird little Zhoutian.

After circulating dozens of times, the pool water became extremely dark, and Cheng Kong stood up from the pool with a happy look on his face.

The warmth in the colorful fountain is already very light, and if you want to absorb it, you have to wait a day before you can do it.

It is impossible for Cheng Kong to stay here, anyway, this colorful fountain may run away by itself, so Cheng Kong lifted the big bow and walked towards the depths of the passage.

Cheng Kong wanted to see what the Black Bull City was like, it was conceivable that for a considerable period of time, Cheng Kong would have to stay near the Colorful Fountain, and if he didn't understand the surrounding situation clearly, Cheng Kong himself would not be steady.

After walking a distance of ten miles, the underground passage branched off and divided into two passages.

One passage is still large and spacious, while the other is a few sizes smaller, and it seems that it should be a branch of the underground passage.

Obviously, this kind of bifurcation is likely to be encountered often in the underground passage, so Cheng Kong immediately named the passage he had walked through before as Passage 1, and the large passage after the fork was named Passage 11, and the small branch passage was named Passage 12.

If there is a bifurcation in the subsequent passage in the future, then it will be followed by analogy, such as channel 111, channel 112, etc., at a glance, Cheng Kong always does not believe that this bifurcation will divide into ten channels at a time.

But even then, just use A for ten, B for eleven, and so on.

Cheng Kong then used an arrow to engrave the names of the two bifurcated passages near the passages so as not to get lost.

After doing all this, Cheng Kong walked towards the No. 12 passage without hesitation.

Compared with the No. 11 channel, Cheng Kong's reason for choosing the No. 12 channel is very simple, this passage is much narrower, and it is likely to be a dead end, so it must be explored and eliminated first, otherwise if one day he escapes for his life and escapes into a dead end, it will be tragic.

Compared with the No. 1 channel, the No. 12 channel is very irregular, sometimes turning left, sometimes turning right, if it is not for the lack of forks, Cheng Kong has to be confused.

The passage was very quiet, only the slight footsteps of Cheng Kong, to be honest, in such an environment, it was really difficult to play sneak attacks, so Cheng Kong didn't have to listen to them every other distance.

Cheng Kong had traveled about twenty miles along the passage when he heard a continuous sound.

It was like flowing water, but very slowly, and from time to time there was a slight popping sound.

Underground river? Cheng Kong shook his head, not quite like it.

The slight popping sound gave it a very viscous feeling.

A few miles closer, some strange screams came over, but they were just screams that didn't mean anything.

Hearing this, Cheng Kong couldn't help but speed up his pace, under the influence of these noises, Cheng Kong's footsteps had been completely covered, and he didn't have to worry about the footsteps revealing his whereabouts.

The air was starting to get a little hot, and even the ground was slightly hot.

The more Cheng Kong walked inside, the clearer the sound came from inside, and there was a strong smell of sulfur.

Without further guessing, Cheng Kong concluded that the slow sound of flowing water should be a magma river, and the slight popping sound was the sound caused by the bursting of the magma bubble.

After a few steps to the end of the passage, Cheng Kong was a little dumbfounded.

It was a vast Underground Realm, and a river of magma with no end in sight flowed slowly through this Underground Realm.

The ground is black, covered with large and small stones, and on the banks of the lava river, some strange creatures are busy, using a windmill to carry the hot lava ashore from the river, and then use a channel to lead the lava into a building converted from a boulder.

Other creatures have lifted some iron spirits out of the boulders and stacked them on a flat ground.

Which creatures are supposed to be little devils?

Cheng Kong hesitated a little, after all, he had never seen that kind of hell-type first-class class with his own eyes.

However, these creatures are similar to Bryn's description, with dark red skin, standing in human form, half human height, thorny tails, pointed ears, a short horn on their foreheads, and holding a small steel fork.

The megalithic building was supposed to be an ironworks, and it seemed that the lava river was rich in iron ore.

If you can capture this iron-making plant, then you will have a source of iron essence.

Cheng Kong took a closer look at this underground realm and found that it was not easy to capture the ironworks.

The distance in a straight line from the mouth of the passage to the ironworks was more than four miles, and there were at least fifty little devils and hundreds of meat worms on this straight line.

Whether it's a little devil or a demon larvae, they're fighting each other.

Since there is a little devil, then the meat worm should be a zero-level creature demon larva of the hell system, the body is like an earthworm, the meat is rolling, and it looks a little pleasant, but when the big mouth at the front is opened, it is a little terrifying, it is full of sharp teeth, and even the little devil will be bitten into two pieces in one bite.

But the little devil always has the upper hand, after all, the speed of the demon larva is a little slow, and before he can open his mouth, the small steel fork in the little devil's hand can insert it into the demon larva a few times.

Everywhere Cheng Kong saw it, this scene was being staged.

I don't know how many little devils there are, the demon larvae fight each other in this underground world, and from time to time there will be little devils or demon larvae who fall down and become food for the surrounding creatures.

They don't wait for the corpse to decompose into an evolutionary ball of light like Cheng Kong, as long as a creature falls, then the surrounding creature will stop fighting and start sharing food.

They eat so fast that the carcasses don't have time to decompose before they turn into pieces of meat and fall into their stomachs.

Cheng Kong had some doubts in his eyes, these little devils and demon larvae seemed to have been fighting, and they were fighting before they came. (To be continued......)
