There was a crisp "click...... and a large area of earth and rock collapsed, revealing the empty and deep cavern inside.

Cheng Yang and the others walked over quickly, looking at the starry spiritual energy stones in the depths of the cave, their mood was not calm. If nothing else, these psionic stones should all be level 4, and their value is far from comparable to these level 2 and 3 psionic stones outside.

"Lord, let's go and have a look first." Tan Chao was the first to ask for his life, although Xiao Bai had entered this natural cave before, and there seemed to be no danger, but at that time, Xiao Bai came in quietly, who knows if there will be any accidents here?

Now in this world, the most unpredictable thing is the rules of heaven and earth, and no one can figure out where this guy will set a trap.

Cheng Yang nodded, and asked Tan Chao to go in first.

Tan Chao stealthily drilled through the hole, and within a few minutes, he came back again.

"Lord, this cave is almost two kilometers deep, and there are no forks in the road along the way, and there are no demonic beasts. But in the deepest part of the river, there is a dark river, and the water is pure black, and it looks very strange. His subordinates had tried to melt quickly if they threw nearby rocks into the black water. It's just that for some reason, the riverbed was washed by the black water, and it was unharmed. ”

Cheng Yang frowned slightly, he didn't care about this thing, after all, there are many weird things in this world now, that is, in the world on the ground, he saw the river that could directly freeze the demonic beast into an ice mound, not to mention that it was now in the mysterious underground world.

"And how wide is the underground river?" Cheng Yang asked.

Tan Chao said: "It's almost more than 20 meters, plus a run-up, it's no problem to jump over this width." The point is that the opposite side is not flat, but a smooth stone wall, as if it were the end of this cave. ”

Cheng Yang nodded and said, "Since there is no danger, then let's go in and have a look together." …… By the way, there are level 5 psionic stones in here? ”

Tan Chao shook his head and said, "The level 5 spiritual energy stone has not been found. However, there are a lot of level 4 psionic stones. ”

Cheng Yang was slightly disappointed in his heart, but he still said: "The level 4 spiritual energy stone is also good, after all, the level 5 spiritual energy stone has the title of a divine stone, and it is not so easy to find." ”

Next, Cheng Yang drilled into the cave, and there were many psionic stones inlaid on the walls of the cave on both sides, most of which were level 3, and occasionally there was a bright storage zài, and those were all level 4 psionic stones.

Cheng Yang estimated it, almost every ten meters. You can see a level 4 spiritual energy stone, think about this cave with a length of more than two kilometers, there are at least more than 200 level 4 spiritual energy stones, right? That's 2 billion psionics, even more valuable than 2 billion psionics.

No one would think that this psionic stone vein only had these level 4 psionic stones, which were only exposed on the surface after all. As for how many psionic stones will be stored in this stone wall, and how many level 4 psionic stones will there be, who can say clearly? Even if there is a level 5 psionic stone in it, it is not necessarily.

However, it would undoubtedly take a long time to find a level 5 psionic stone in this vein. With the current form, it is impossible for them to mine the psionic stones here.

At this time, Cheng Yang had already instructed the ten carvers accompanying him to start collecting these Level 4 spiritual energy stones that were exposed on the surface. Cheng Yang, the spiritual energy stone buried in the rock, can ignore it for the time being, but he will not give up when he is exposed. One is 10 million psionic value, who would turn a blind eye?

Half an hour later, Cheng Yang and the others arrived at the cave to go deeper, just as Tan Chao said. This is indeed a black dark river, and the water of the river is like devouring all things in heaven and earth, which makes people feel cold in their hearts.

On both sides of the river. The rocks, which were about twenty or thirty centimeters thick, had also turned inky black, and the black was so pure that there was no blemish at all.

Cheng Yang didn't know if the black water didn't corrode the riverbed, if it was because the river water caused these rocks to change qualitatively.

The strangest thing is that the riverbed that Cheng Yang and the others can see at this moment is only fifty or sixty meters long, flowing out of a cave on the right and pouring into another cave on the left.

The two caves are just the size to accommodate the water of the river in and out, and there is not even a single gap.

It was as if a black dragon was passing through the belly of the mountain.

Cheng Yang tried to observe the black river water with reconnaissance techniques, but the information he got turned out to be just ordinary river water, which made Cheng Yang vomit. If this is all ordinary river water, then there is no ordinary river water in the world.

Spit bad is spit bad, Cheng Yang really has no way to take this river water.

"Xun Ye, do you know what's going on in this river?" Cheng Yang asked with a glimmer of hope.

Xun Ye shook his head and said, "My subordinates don't know, and I can't feel what this river water does. ”

Cheng Yang said helplessly: "So it seems that I have to try it first, if I can find something that can hold some of this black water back, I can go to the tavern to inquire about the news." ”

Liu Xiyue immediately said: "Lord, it's not difficult to put this black water back, isn't there this black rock on both sides of this river?" Ask the carver to take some of the rocks and make them into containers. ”

Cheng Yangxi said: "This is a good way, and I will find a carver to come over and get this thing in a while." ”

"So what do we do now?" Tan Chao asked.

Cheng Yang said: "There seems to be no other treasures here except for the spiritual energy stone, after we go out for a while, we will seal this cave again, and we will come to mine it later." ”

The rest of the people also have no opinion.

Half an hour later, all the exposed level 4 psionic stones were excavated, a total of 214 pieces, which was definitely a huge fortune.

Of course, the number of Level 3 Psionic Stones embedded in the cave wall is no less than tens of thousands, if you only calculate the Psionic value, I'm afraid it is more than these Tier 4 Psionic Stones combined, but if you want to talk about the value, it's hard to say.

Subsequently, Cheng Yang and the others did not immediately walk out of the spiritual energy stone vein, but let those carvers practice in it for an hour.

Cheng Yang had determined one thing before, that is, the cultivation speed of the warrior was related to the environment, the interior of this Divine Dragon Forest was definitely a relatively advanced region, and at the same time, this was also in the spiritual energy stone vein, and the concentration of spiritual energy in it was definitely very high.

Sure enough, after an hour of cultivation, they came to a very surprising conclusion, the cultivation speed of ordinary fighters here has almost increased by about 60%, which is much stronger than most houses.

Although the environment here is good, but when the strength of Luofeng Town has not developed, it cannot be developed and utilized, and Cheng Yang has an unspeakable depression in his heart every time he thinks of this.

Next, Cheng Yang instructed the carvers to start blocking the entrance to the cave, which was much more difficult than mining, and it took them nearly two hours to completely block the passage to the natural cave.

It was late at night at the moment, and Cheng Yang and the others went directly back to Luofeng Town.

The next morning, Cheng Yang and the others returned to the mine again and continued their journey to explore the Shenlong Forest.

At this time, Tan Chao said that he sensed that there was a treasure in front of him, and at that time, because Xiaobai found the dragon mouse, and then luckily got the crystallization of the demonic beast, which made this harvest extremely rich. It also made them delay here for two days.

Although Cheng Yang's expectations for the treasure inducted by Tan Chao have decreased a lot at this moment, it is also a treasure after all, isn't it? Cheng Yang naturally had to find a way to get his hands on it.

"Lord, actually, I think we should still bring those who have quarrying skills here, after all, we have sealed all the exits, and let them mine quietly in the cave, there should be no danger. It's a big deal to use teleportation gems and return stones every time you enter and exit, which can also increase the income of the territory, right? Tan Chao was still talking about those spiritual energy stones.

Cheng Yang shook his head and said, "We don't know the purpose of these psionic stones yet, if we just convert them into psionic value, it would be a waste." Now that we've collected more than two hundred Level 4 Psionic Stones, we just want to try our luck and see if we can get some news from other people. ”

Tan Chao sighed slightly, it seems that these spiritual energy stones can only be placed here for the time being.

Along the way, the five people and one beast carefully moved forward, clearing out the demonic beasts that stood in the way.

When they finally arrived at the place where Xun Ye sensed, what they saw was a group of more than a dozen demonized beasts.

These demonic beasts look like grizzly bears, but they are much larger than ordinary grizzly bears, and there is a faint tendency to surpass the current size of Xiaobai. When he stood up, he was as tall as a three-story building, an absolute behemoth.

When Cheng Yang saw this scene, he was immediately extremely entangled.

Obviously, in the face of such a group of demonic beasts, they can't be their opponents, even if Liu Hao and the other masters of Luofeng Town are all transferred, it is impossible to defeat the other party.

Even if these demonic beasts only had the strength of the early stage of the third order, the result would not change in any way.

Cheng Yang used the mirror of the evil eye to look at a blood-red stone surrounded by the group of demon bears, it was so familiar.

No wonder Xun Ye would say that this thing is helpful for improving his strength, this turned out to be a Nirvana Divine Stone.

Although Luofeng Town already has a Nirvana Divine Stone, who would have too many good things? Besides, such a treasure is not the more it appears, the weaker the effect, for a territory, every Nirvana Divine Stone can exert its true value.

"Withdraw! We can't take this thing, and when we get stronger, we'll come back to trouble these guys. Cheng Yang muttered softly, now those demon bears have noticed them, but because the other party has a treasure to guard, they didn't make any moves, just stared at Cheng Yang and the others with that murderous look.

Liu Xiyue and the others are also very self-aware, two or three third-order early stage demonic beasts can still make up their minds, even if there are two or three more, it is more certain to greet the territory masters. But these are twelve powerful demonic beasts in front of them, and this is not something they can shake.

Fortunately, they are not in a hurry, after getting the crystals of demonic beasts, they don't need to wait too long, they will have the strength to fight these demonized beasts, and it will not be too late to come back at that time. (To be continued......)
