Su Chen took Lu Shan to inspect the giant mine that the Li family had transferred to him, and arranged for people to take over the jurisdiction of this mine.

After that, they went to the Earth Fire Cave that once belonged to the Xue family.

This earth fire cave is in the large area of surrounding valley mountains outside Tianque City, only dozens of miles away from the city.

This mountain range around the valley was once an ancient mining area, and the city of Tianque was built on the mountain.

However, the spiritual mines in this mountain were dug up very early, and the mines were abandoned, and many of them were even used as temporary temporary caves to escape from ice and sand storms.

But one of the caverns was quite special, it dug so deep that it inadvertently dug through a geofire molten cave deep underground.

There is a huge underground crack in this underground cavern, which stretches for tens of thousands of miles. The magma in the depths of the crypt spewed blazing fire, burning for an unknown number of thousands of years.

This earth fire is much better than spiritual charcoal.

The first is that the earth fire has almost no cost, and there is no need to spend a lot of money to cut down the spiritual wood and burn it into charcoal, which is inexhaustible. The second is that the power of the fire source is very stable, which is very suitable for alchemy and refining for months, or even years.

Therefore, this earth fire molten cave has been spent by the senior monks for tens of thousands of years, and hundreds of alchemy secret rooms and refining secret rooms have been opened up by the senior monks. From the first-order power earth fire to the fourth-order power earth fire, there is everything to meet the needs of Tianque City.

Originally, these fire chambers belonged to the excavators.

But tens of thousands of years have passed, and over time, this earth fire molten cave was finally bought and occupied by the Xue family, the most entrenched power in Tianque City, blocking the entrance, and outsiders could not enter at will.

If the alchemists and refiners of Tianque City wanted to use it, they had to pay a sum of spirit stones and lease the Xue family's earth fire at a high price. So much so that the high-level alchemy refining workshop in Tianque City had to look at the Xue family's face.

However, now this place belongs to the Su family.

...

Su Chen and Lu Shan came here with some Su Fu monks and took over the Earth Fire Cave from those frustrated Xue Family Monks, and then they entered the Earth Fire Cave together.

Lu Shan had also refined magic weapons in this Earth Fire Cave, and he was obviously quite familiar with this Earth Fire Cave.

"Ancestor, this Earth Fire Cave has more than ninety first-order to third-order Earth Fire Chambers, and three Fourth-Order Infant-level Earth Fire Rooms. The top level is the fourth-order earth fire room, if you want to refine the elixir and magic weapons above the fourth order, only here can you do it. ”

Lu Shan introduced.

"Hmm. ”

Su Chen nodded slightly.

This fire chamber is a chamber excavated along the banks of a magma river with a crack in the ground. A secret chamber built by channeling magma and fire.

The deeper you go, the more powerful this earth fire becomes, and the higher the level of the secret room.

They walked up the stone steps to the depths of the Earthfire Molten Cavern.

The underground cave rock is hard and dark, very difficult to dig, and from time to time you can see some Qi refining and foundation building monks sweating profusely, busy carrying ores.

And the alchemy and refining masters of the Jindan Realm were refining, busy with their apprentices.

When they reached the vicinity of the fourth-order secret room, only the Jindan monk was left to move here. The shields of those foundation building monks could not withstand the erosion of the fiery qi and could not stay.

It is very rare for the Primal Infant Ancestors to come here to do their own alchemy refiners, and the elixirs they need are all refined by the Jindan Grandmaster.

The flames of the fourth-order earth fire were fierce enough for the Jindan monks to use.

However, even the fourth-order earth fire chamber is rarely used. After all, there were only seven or eight ancestors in Tianque City, and they wouldn't often need to refine expensive pills and magic weapons.

Su Chen asked lightly, "Is there a fifth-order earth fire here?"

Lu Shan was stunned for a moment, thought for a while, shook his head and said: "The fourth-order earth fire secret room was dug out by the ancestor of the Yuanying, and it is already the limit to be able to control the fourth-order earth fire, and the villain doesn't know if there is a fifth-order earth fire underground." But even if there were, I don't think I would need it... ”

After all, the power of the fifth-order earth fire was too strong and too fierce for only the Avatar Cultivator to use.

Not long after, they followed the magma river to the deepest part of the earthfire chamber, and had reached the end of the earthfire cave.

There is still a molten river ahead, and there is a way to go, but you can't go any further.

The flames of the magma river here are constantly erupting, and the heat is overwhelming. Monk Jindan couldn't stay outside the fourth-order secret room for more than a few hours before leaving.

Only the ancestors can stay here for a long time. However, there was nothing but molten ground fire inside, and there was no need to go inside.

"Okay. You go back first, I will refine something in this fourth-order secret room, and it is estimated that it will take a while to go back. ”

Su Chen said.

"Yes, Ancestor. ”

Lu Shan nodded hurriedly, turned around and left, but he hesitated, turned around and mourned: "Ancestor, I'm afraid that I will go back alone... In case the children of the Li Xue family come to me in trouble, how can this be good?"

He is a Jindan monk, and no one dares to touch him with Su Chen's ancestor. I am afraid that he will be alone and will be retaliated against by the children of the two families.

Su Chen said lightly: "Don't worry." When the children of the two families are in trouble with you, you tell them. As they deal with you, the ancestors will clean them up. If they dare to kill you, it doesn't matter, the ancestor will turn around and take the two heads of Li Xi and Xue Tie and pay tribute to you. ”

"Xie Ancestor!"

Lu Shan kowtowed, was grateful, and went back to Tianque City with peace of mind.

He immediately understood that the Li and Xue families were certainly big families, and there were many people. But if they really dared to play despicable means to assassinate the Su family's subordinates, they would be even more afraid.

is still the same sentence, no matter what means are used, in the end, you must rely on the strength of the ancestor to support your back, otherwise it will be regarded as death.

Killing him Lushan will not hurt the Su family in the slightest.

But Su Laozu will definitely use this as an excuse to retaliate, and exchange the heads of Li Xi and Xue Tie for his heads in Lushan, and the Li and Xue families will definitely know that they can't make it.

As long as this sentence is said, no one in the Li and Xue families dares to touch him at all, but they are afraid that something will happen to him.

...

Su Chen stopped by the magma river for a while and looked back. Lu Shan had already left, and the underground lava river was bubbling and bubbling, and there was no one nearby.

Only then did he turn around and enter the fourth-order Earth Fire Secret Room, closing the stone door of the Secret Room.

This fire chamber is the size of a hundred zhang space, surrounded by natural hard stone walls, resisting the invasion of the fiery qi from the outside world.

And in the middle of the ground, a hole was dug in, and golden earth fire poured in through it.

In the secret room, Su Chen took out a pair of formation flags and laid down a simple shielding formation to prevent the breath of the fifth-order gourd from leaking out and alarming outsiders.

After that, he sat cross-legged in the middle of the Earth Fire Secret Room, from the middle of the Sea Spirit Mountain.

The Seven Treasure Gourd Spirit Vine is growing very well, and among the seven gourds, only the cyan wooden gourd has reached the maturity of the god transformation stage. The other six mouths will continue to absorb the aura and grow.

Su Chen also hesitated.

Do you want to continue to raise these Seven Treasure Gourds? Raise them to break through the fifth-order god level, or even reach the stronger sixth-order Mahayana level. See how powerful they will be?!

But Su Chen thought about it for a long time and felt that it was not very reliable.

In the entire Beiming Continent, there are countless Yuanying monks in the Tongtian Dynasty, but after three or five hundred years, there are only a few people who can seize the opportunity to transform into a god and finally set foot on the transformation realm.

The rest of the countless monks all stopped at the Yuan Infant.

It can be seen how difficult it is to transform into a god, and how tragic the competition for the opportunity to transform a god is.

Whether he can transform into a god or not is a 1 in 10,000 chance.

Although Su Chen had the heart to seek the Dao of Transformation into a God, he would not be blindly confident, feeling that he had this opportunity to compete for the opportunity to transform into a God from the hands of countless powerful Yuanying Cultivators.

If you have the most magic weapons, you can use them across the first level.

That is to say, the Jindan monk can only use the small supernatural power level magic weapon of the fourth-order Yuan Infant Realm at most, and the power can only be exerted by about one or two percent. With the great supernatural power level magic weapon of the fifth-order god realm, I am afraid that I can't even hold it.

It's the same with my own infant ancestor. If you can't even step into the Transformation Divine Realm, what are you doing by spending countless efforts to cultivate a sixth-order Mahayana Realm gourd?

"I don't have a top-level magic weapon in my hand now, and compared to those top Primal Infant Ancestors in the Beiming Continent, my combat power is definitely not superior.

Only by refining this set of seven-mouth god-level gourds can you compete with them. In the future, once the opportunity to transform the gods is discovered, they will win the battle. Otherwise, where will it be your turn to fight for the fate of the gods!"

Thinking of this, Su Chen gritted his teeth and picked the blue light that grew on the spirit vine of the Seven Treasure Gourd, which was extremely heavy, not to mention the million-pound fifth-order wooden gourd from the Spirit Vine of the Seven Treasure Gourd, and took it out from the Spirit Mountain.

In an instant, this fifth-order god-level cyan gourd was full of aura, and the treasure light was shining, and it was rampaging in the secret room, trying to fly out.

It's just that it is locked in by the thick stone wall of the fourth-order earth fire room, and the breath is also shielded by the formation flag, so it can't leak out.

Su Chen raised his big palm and held down the rampage cyan gourd, making it unable to move a bit.

Although it is a god-level gourd, it has not given birth to spiritual intelligence, and although it has some instinctive escape reactions, it does not know how to fight back.

This cyan gourd has an unusually hard shell.

Su Chen tried to slash it with a fourth-order spirit soldier without moving, and he didn't know what was inside, it was so heavy.

Su Chen, as a primordial ancestor, was also very difficult to hold this green gourd, and put it on the fourth-order earth fire to refine it.

However, the fourth-order ground fire burned the fifth-order wooden gourd for three days and three nights, and it couldn't burn it at all.

This fourth-order earth fire is very powerful, but it is still not enough in front of the God Transformation Gourd. As if burning a piece of cold iron over a warm fire, it still didn't move for three days and three nights. It is estimated that without decades of hard work, I am afraid that even its shell will not be able to burn.

Su Chen couldn't help frowning, a little disappointed.

"It seems that the fourth-order earth fire is almost useless against this green gourd. You still have to find a fifth-order earth fire to refine this god-level gourd. ”

Su Chen stood up, shook his body, and changed into a fourth-order Mithril armor, wrapping himself tightly to protect himself. The heat of the flame from the outside world is discharged.

Then, he put away the wooden gourd and the formation flag, left the fourth-order earth fire secret room, and continued to go to the depths of the underground cave.

He wanted to see if there was a fifth-order earth fire in this molten river.

His Seven Treasure Gourd already had a cyan wood gourd that had broken through the fifth-order Transformation God Realm, but he had to use the fifth-order earth fire to refine it. It can't be refined by the fourth-order earth fire alone, and the power is far from enough, and it can't be refined.

If you can't refine it into a magic weapon of the great god level, it will be useless to have this treasure in your hand.

Su Chen walked along the molten river for a full day, heading towards the end of the molten river, and the earth fire became hotter and hotter.

The fire aura is extremely strong, and the flames are everywhere.

This underground is like a stewed pot, and the heat of the flame emitted by the bubbling molten ground fire cannot be dissipated at all.

As a primordial ancestor, Su Chen wore a set of mythril armor that spelled the law, but after walking in the high-temperature flames for a long time, he still consumed a lot of his mana.

From time to time, he took the high-level elixir that replenished his mana, and walked along the molten river in one breath, hundreds of thousands of miles away.

The direction of the lava river is to the south.

This means that he did not go in the direction of the Beiming Continent, but in the direction of the Beiming Sea.

It is estimated that it has reached the depths of the Beiming seabed, which is hundreds of thousands of miles away from the mainland.

Finally, he stopped on the shore of a huge molten lake hundreds of miles.

Here, ordinary ancestors can't reach it at all.

It's too hot, it's too hot, it's too hot. If it weren't for Su Chen's body wearing Mithril armor, I'm afraid he would have been unable to withstand the fire poison invasion and would have been forced to withdraw.

Su Chen looked up in surprise and found that above this lava lake for hundreds of miles, a big mountain was raised.

The raging earth fire jumped along the top of the mountain.

Could it be that this place is still an undersea crater? But I don't know if there is a fifth-order earth fire here?!

Su Chen glanced over.
