Chen Dasheng nodded, and there was no objection.

Immediately, the Zhuang sister and brother also came over and joined the two of them, and the four of them lined up in a row, secretly raising their internal strength, ready to smash the boulder.

At this moment, Nangong Chengfeng suddenly stood up straight, with a hint of caution on his face.

"What's wrong? Brother Feng? Zhuang Shaofen was a little surprised.

Nangong Chengfeng frowned and said, "Before coming, I heard the uncle say that ten years ago, when they came to this cave, there was a mastiff guarding the cave, and this stone was found by my father and uncle to block the entrance of the cave. ”

"Mastiff? How strong? Zhuang Shaofen's face also flashed a trace of caution.

Nangong Chengfeng shook his head, "That's the realm of an eighth-level martial artist for both uncle and my father, but I injured that divine mastiff and couldn't kill it, so I think it should be very strong." ”

"Phew!"

Zhuang Shaofen gasped when she heard this, the two eighth-level martial artists failed to kill it, the strength of that divine mastiff could already be seen, and now that ten years have passed, if she is still alive, how strong it has become, she can't imagine it.

"This stone can't be opened?" Chen Dasheng asked, what kind of mastiff is not a mastiff, he doesn't take it to heart, he still wants to finish his work as soon as possible, so that he can go out to find someone.

Nangong Chengfeng thought for a while and said, "Since they are all here, of course they have to be opened, otherwise how can they go back to their lives, although the mastiff is strong, it may have died a long time ago, after all, it was sealed in the cave, there was no food, and it was injured again!" ”

Letting go of the worries in their hearts, the four of them stood together again, Nangong Chengfeng said, "I'll count one, two, three, everyone will work together to punch the boulder." ”

The three of them nodded, and Nangong Chengfeng began to have luck, "One, two......"

"Three!"

As soon as the word 'three' fell, the four fists suddenly blasted out like cannonballs, especially Chen Dasheng, who directly infused the physical strength of his whole body, and with the assistance of some internal strength, at least the violence of the power of the three sects broke out.

The four of them are all masters, and under the joint force, the tricky force is even more terrifying, although the boulder is hard, but under the violent bombardment of the four people, there are many cracks in the click, and in an instant, it is like a spider web densely covered out, and it explodes in an instant.

"Boom!"

There was a violent tremor in the cave, and the boulders were blasted into pieces of rubble, flying everywhere, causing Chen Dasheng to think that the entire cave was about to collapse.

The shock subsided, the ground was full of stones of different sizes, Nangong Chengfeng looked back at Chen Dasheng very unexpectedly, just now they didn't try, but there was no effect at all, with Chen Dasheng's joining, it was so easy to smash the boulder, Nangong Chengfeng couldn't help but re-examine this young man who was valued by his grandfather.

The strength of Chen Dasheng's punch is very strong, Nangong Chengfeng even feels stronger than his own strength, it is obvious that Chen Dasheng is not as simple as he seems on the surface.

A dark hole reappeared in front of everyone's eyes, Nangong Chengfeng didn't say anything, the flashlight in his hand shone inside, and he took the lead and walked into the cave.

Immediately Zhuang Shaoxian and Zhuang Shaofen also walked in, no one paid attention to Chen Dasheng, Chen Dasheng stood in place for a while, couldn't hold back the curiosity in his heart, and ran in.

——

The dark cave was full of secluded forests, but the more people walked inside, the more they felt that the temperature around them was slowly rising.

This iceberg contains geothermal energy, which Chen Dasheng knows well, and the hot springs under the mountain are affected by geothermal energy.

Nangong Chengfeng walked in the front, followed by the Zhuang brothers and sisters, and Chen Dasheng consciously fell behind the most, there were many small springs in the cave, and when the flashlight shone, I saw that the water in the spring was bubbling like magma.

The heat was steaming, like falling clouds and fog, Chen Dasheng secretly estimated that the temperature here was already forty or fifty degrees, and several people were like they were in a sauna, and their bodies were soaked with sweat.

Nangong rode the wind very slowly, as if he was faintly guarding against something, and the expressions on the faces of the Zhuang brothers and sisters were also very solemn, each holding a flashlight in his hand, and kept scanning the surroundings, for fear of encountering any unexpected situation.

"Brother Feng, it seems that the god mastiff is no longer there!" Walking forward for a while, Zhuang Shaofen lowered his voice and faced Nangong Chengfengdao.

Nangong rode the wind and said, "Don't be careless, listen to the uncle, that mastiff is very powerful, if it is not dead, it will be troublesome!" ”

Zhuang Shaofen bowed slightly, this place gave her a very depressed feeling, not only the temperature was uncomfortably high, but even it was a little difficult to breathe, and the more she walked inside, the more depressed she felt.

"What is a mastiff?" At this time, Chen Dasheng, who was walking behind the most, asked coldly.

Nangong Chengfeng thought about it, and didn't seem to have any intention of hiding it, so he said directly, "Do you know what a mastiff is?" The mastiff is the best in the mastiff, the mastiff in the mastiff, my Nangong family's cultivation of the 'Nanming Separation from the Fire Technique', requires a large number of fire crystals, and there are a lot hidden under this glacier, but it is guarded by a mastiff, ten years ago, my father and uncle once came to take it, because the mastiff obstructed, did not take much and left in a hurry, and now it is almost used, so the uncle asked me to take it! ”

It can be regarded as a confession, since Chen Dasheng has already followed, there is no need for Nangong Chengfeng to hide him, and after a while, he will find the crystal of leaving the fire, Chen Dasheng will know about Lu Dao even if he doesn't want to know Lu Dao, and if he says it at this time, it will not make Chen Dasheng suspicious.

"Crystal of Separation from Fire?"

Chen Dasheng was stunned for a moment, but he didn't know what Lu Dao was, the Nangong family's kung fu was domineering and hot, which Chen Dasheng had already understood, and now it seems that most of it is related to this Crystal of Fire.

Nanming is away from the fire? It turns out that the Nangong family's cultivation method is called Nanming Lihuo Jue!

Chen Dasheng didn't ask much, followed behind the three of them, and walked straight to the depths of the cave, looking around vigilantly along the way, listening to Nangong Chengfeng say that the god mastiff was powerful, Chen Dasheng naturally had a long heart.

After a while, an open space appeared in front of him, about 100 meters in circumference, surrounded by stone walls, and a dome like the bottom of a pot enveloped the entire space.

The stone walls were dotted with stars, as if there were countless fires flickering, and before he walked in, Chen Dasheng felt a strange and scorching energy filling every corner.

"Brother Feng, it's the crystal of fire!" Zhuang Shaofen pointed to the shiny things on the stone wall, and let out a suppressed exclamation.

"Don't worry!"

Nangong Chengfeng's breathing was also a little short, but it was obvious that he didn't mess up, and he couldn't tolerate the slightest sloppiness until he was completely safe.

The vigilant looked around, only in the center of the cave, there was a small pool, like a hot pot bubbling hot, there were only a few small forks, I don't know where the road leads.

Didn't find any danger, Nangong Chengfeng secretly relieved a little, it seems that the mastiff should be gone, the mastiff is a creature, for the people who violate its territory, it has a very strong aggressiveness, if the mastiff is still there, his own people have gone deep into here, it is impossible for the mastiff not to appear.

"Hurry up and get the Crystal of Fire and get out of here." Although he judged in his heart that the mastiff was dead, Nangong Chengfeng still didn't dare to be careless, and immediately gave an order to the Zhuang brothers and sisters, but he himself had already run towards the dotted stone wall.

The stone wall is inlaid with pieces of naturally formed or dark red or fiery red stones, the big ones are the size of a fist, and the small ones are only the size of a fingernail.

The Zhuang brothers and sisters also followed suit, the speed was naturally not slow, and Chen Dasheng also rose to the heart of curiosity, stepped forward and grabbed a protruding stone, and directly broke it off with brute force.

"Is this the Crystal of Separation from Fire?" Holding the stone the size of a ping-pong ball in his hand, Chen Dasheng only felt that the stone was very hot, and there seemed to be a mysterious force in it, but it was not very strong.

What can make the people of the Nangong family so moved, it must be a good thing, entering the treasure mountain, how can they return empty-handed, and Chen Dasheng will not do the loss-making transaction, and he will dig it up with great interest, anyway, this thing is not the Nangong family, if others can dig it, then he can also dig it himself.
