As for the thunder, the power of sound wave, and the burning of fire, they can't be used for much.

After the three men had completely entered a cave, Chu Chen forced the mangtian beast to open with a move, and burned the fire at a very fast speed. Before the three men entered the cave, he arranged a fire barrier to keep the ancient insects away.

As a result, although Bai Yuhan, lion demon and guziyi were safe, he was trapped in a desperate situation, alone in the face of ancient insects and mangtian beasts.

"It's just the beginning of the show!"

Chu Chen took a look at mangtian beast, licked his mouth, and his eyes showed bloodthirsty light. He immediately opened Najie and took out ten groups of heart demons with great energy. The terrible smell filled the mangtian beast, and he looked at Chu Chen and made a strange roar.

"Try the power of the heart demon!"

Chu Chen throws out the energy body of ten regiments of heart demons, and at the same time, attaches a trace of Yuan force to it.

When the ten regiments of heart demons were close to mangtian beast, Chu Chen used Yuan Li as the fuse to open the cage of heart demons. Suddenly, the extremely terrible power swept out.

We should know that each group of heart demons is separated from an Archean strongman, which is equivalent to the strength of a part of archaic strongmen, and its strength is almost incalculable.

Chu Chen in the thirty-three days of demon, refining one of the weakest was almost occupied by the body, from which we can see the fierce.

Of course, if it is a normal warrior's heart demon, even if it is fierce, it can't be detonated, because the evil power is not dynamite or pill that can be exploded.

However, Chu Chen's 108 regiment demons are different because they were refined into pure energy by a strong warrior and compressed in the cage. As long as there is a yuan force touching it, it will be swept out in an instant, turning into an extremely terrible force and swallowing all objects.

This is also the reason why Chu Chen dared to come to the dark demon cave. If all the 108 inner demon energy bodies were released from the cage, their destructive power would be extremely terrible, and it would probably turn a place into a forbidden area like hell.

Of course, Chu Chen won't release all of them easily. For him, every energy body is a treasure, which is very helpful to his cultivation. But now he can't refine all of them. Once he forcibly opens the cage and devours it, maybe he will be occupied by the heart demon.

Although it has been compressed into an energy body, it is after all the heart demons of the ancient strong. The residual power of the heart demon can make itself suffer terrible suffering. That consciousness can not control the feeling of the body, Chu Chen does not want to experience the second time.

The ten energy bodies swept out of the cage and turned into black air flow, like a space-time storm, which immediately ravaged the entire underground space.

The first to bear the brunt is mangtian beast. Because the body is too big, it is severely impacted by the rebellious heart demon energy.

"It's a pity that I can't control the power of these demons. Otherwise, I will play a greater role if I want to."

At this time, Bai Yuhan, lion demon and Gu Ziyi are running in the cave they are choosing. Hearing the explosion behind him, he is very nervous. Chu Chen will not use any taboo method and die with mangtian beast?

Three people uneasy thinking, eyebrows locked, if Chu Chen has any accident, all his life, will be in guilt.

After throwing out the ten group heart demon energy body, the mangtian beast has been completely restrained, and Chu Chen no longer stays. According to this situation, before long, the dark grotto will collapse.

The body immediately swept away, toward the cave where Bai Yuhan three people disappeared. The burning fire was sprinkled on the place where they passed, and the ancient insects like ants were all shaken out.

These ancient insects, very spiritual, found Chu Chen to escape, more ferocious encirclement, and from the rest of the cave, there are still more ancient insects, continue to converge on this side, can not be destroyed.

At this time, even the fire can not be burned to death, just put out a batch, and quickly rushed to a batch, three circles inside, three outside, surrounded the Chu Chen.

The mangtian beast was restrained and could not be defeated by these ancient insects. Chu Chen raised his head to the sky and burst out to drink. He even used the power of the sound wave and turned into an incomparable sound wave.

At the same time, the black swords are covered with blazing fire. With the killing swordsmanship, it looks like a fire dragon flying, killing countless ancient insects directly.

At this moment, Chu Chen is crazy, his eyes are red, if you let him know, who is behind the scenes, never die!!

Brush, Chu Chen once again opened the ring, took out ten groups of heart demon energy body, opened the cage in the endless ancient insects, and suddenly the terrible power of the heart demon, like a wild beast, pounded out, causing chaos here.

Countless ancient insects, devoured by the power of the heart demon, turned into residue and disappeared.

At this time, mangtian beast was shocked by the force of ten demons. It roared up to the sky and shot it with one paw. The whole underground world was in complete chaos.

Seeing his masterpiece, Chu Chen grinned with a cold smile. His body twinkled and disappeared into the cave in an instant. He slashed the stone wall with a black sword. Suddenly, dozens of huge stones fell down and sealed the hole directly.After that, Chu Chen ran away like a wild horse and ran out of the country!

"I must go back to see what happened. I can't leave Chu Chen behind."

At this time, Bai Yuhan's tone is firm, the dark demon cave is obviously going to collapse. With the strength of Chu Chen, it is impossible to cause such a result. It must be something he has used, and it is a very dangerous means.

The lion demon and the ancient Ziyi didn't refuse. Chu Chen was their friend and couldn't leave him. But just as they turned around, a shadow came from the depths of the cave, brushing it, and almost in a blink of an eye, came to the three people.

"Don't ask me anything. Come with me!"

This is the voice of Chu Chen. When the three people react to each other, Chu Chen has already grasped Bai Yuhan with Yuan force and quickly swept to the front.

See, lion demon ancient Ziyi, don't ask to know, something big is going to happen.

Immediately, the yuan force moved out, followed by Chu Chen.

There was no ancient insect attack, and the four were unimpeded until three hours later, they shot out from the dark demon cave.

As soon as they landed on the ground, behind them, the towering dark Grottoes made an earthquake like roar from the inside.

The stone wall suddenly split, countless huge stones, from the top of the mountain, rolling down, stirring out endless dust.

"The dark demon cave is going to explode. Back off!"

Chuchen burst into a drink, and led the three people to fly thousands of feet away. Looking at the front from afar, he saw the dark demon cave, which had completely cracked. At this moment, the magnificent giant peak was fragmented.

It seems that there is a kind of majestic force, raging in the mountain, and like a monster, to recover from the earth.
