The Black Market and the Martial City Academy Palace have always been mortal rivals, and if Langxin is allowed to release the black market evil people imprisoned in the Red Sky Secret Mansion, it will definitely be a disaster for the students who enter the Red Sky Secret Mansion.

For Zhang Ruochen, it is also quite unfavorable.

"Langxin must be eliminated, if he succeeds, I will not be able to move an inch in the Red Sky Secret Mansion. ”

Zhang Ruochen summoned Xiao Hei out from the inner space of the space-time crystal.

Xiao Hei's body became the size of a lion, his waist and legs were thick, his stomach was very swollen, and his round eyes were the size of a bowl. It has a pair of black wings growing from its back, which when unfolded, are eight meters long and wide.

"Xiao Hei, I'll go and follow Langxin first, you stay here and wait for Senior Sister Duanmu, if she enters the Red Sky Secret Mansion, let her come to the Magma River Valley immediately to help me. Zhang Ruochen said.

Xiao ****: "That's a strong man in the early stage of the Earth Extreme Realm, are you sure you can't catch up with it or send it to death?"

"If he is allowed to release the evil people in the black market, then there is really no way to heaven and no way to enter the earth. Zhang Ruochen's eyes were firm, since he had made a decision, he would not change.

Xiao Hei nodded and said, "Okay, then you have to be careful, this place is a little weird, I feel that there seems to be the breath of other powerful beasts, don't accidentally die here, and I will be affected." ”

Zhang Ruochen released the space realm, and his body disappeared directly in place.

Zhang Ruochen did not really disappear, but used the power of the spatial realm to distort the space around his body, causing a kind of visual blind spot.

It is precisely because he controls the space domain that Zhang Ruochen has the confidence to track down Langxin, even if he is not Langxin's opponent now, at least he is sure to escape from Langxin's hands.

Looking for the traces left by the heart of the waves, Zhang Ruochen walked step by step towards the depths of the Red Sky Secret Mansion.

The Red Sky Secret Mansion, located deep underground, is the lair of the four-winged earth dragon, occupying a fairly vast underground space.

Along the way, Zhang Ruochen could see Bai Sensen's bones, as well as some remnants inserted in the white bones. There are both the bones of humans and the bones of brutes.

After chasing forward for about ten miles, Zhang Ruochen found the figure of Langxin.

Langxin walked down a stone staircase and walked cautiously, beside him, a raging river of magma.

Zhang Ruochen was about to follow, when suddenly, the sound of a hurricane sounded.

"Whew!"

A crimson heat wave blew from the depths of the Secret Palace, and the wind was very strong.

Zhang Ruochen hurriedly inserted the Snow Dragon Sword into the ground to stabilize his body, and at the same time used the power of the space domain to reduce the wind power of the heat wave.

The stone wall not far from Zhang Ruochen cracked a finger-wide gap.

"Smack!"

The gap grew larger and wider, until it became more than a meter wide.

"Whew!"

The deafening roar of the beast came from the cracks in the stones.

A tentacle more than ten meters long covered with a black carapace flew out of the crack in the stone, tightly wound Zhang Ruochen's body, and dragged it towards the crack in the stone.

Zhang Ruochen's arms were tied, and he could only use his five fingers to pinch the hilt of the sword and stab the snow dragon sword upward.

"Bang!"

The seventh-order True Martial Weapon-level Snow Dragon Sword was pierced on the carapace of the black tentacle, and sparks emerged, but it didn't even pierce the carapace.

That tentacle used more force to drag Zhang Ruochen to the edge of the stone crack. Zhang Ruochen used one foot to step on the stone wall, trying to support his body.

"What kind of brute beast is it, it is so powerful with just one tentacle, if it is dragged into the stone crevice, wouldn't it be a dead end?"

Hearing the footsteps, Zhang Ruochen turned his head, looked behind him, and found that Langxin actually walked over this way.

Langxin stared at Zhang Ruochen, who was entangled in black tentacles and couldn't move, with a cruel smile on his face, "There is a way in heaven that you don't go, and there is no door in hell for you to break in." Zhang Ruochen, go die!"

Langxin hit the flying knife again and slashed towards Zhang Ruochen's neck.

Zhang Ruochen used the power of space distortion to make the flying knife change its direction slightly. The cyan throwing knife flew past Zhang Ruochen's cheek and slammed into the black tentacle.

With a snort, the cyan flying knife was inserted into the black tentacle three inches deep and embedded in the black tentacle.

Just now, the reason why Zhang Ruochen's Snow Dragon Sword couldn't pierce the carapace of the tentacles was because Zhang Ruochen's arms were tied and he could only use the power of five fingers.

If the strength is not enough, the impact force is not enough, and naturally it cannot pierce the carapace of the tentacles.

The cyan throwing knife is not only powerful, but also extremely fast, so it can hurt the tentacles.

The creature in the crevice let out an even more deafening cry as the thick stone wall shook and the crack widened.

"Wow!"

The second tentacle flew out of the crack in the stone and whipped at Langxin's body, and the powerful force whipped Langxin out of the air. Fortunately, he blocked the tentacles with his arms, and he wore the sixth-order True Martial Treasure-level arm guards Tie Kai on his arms, blocking most of his strength.

Otherwise, the blow just now would have seriously injured him.

"What kind of monster is it?" Langxin looked at his blood-soaked arms and stared in shock at the wider and wider stone wall.

His current strength is a few points stronger than that of the master in the middle stage of the Earth Extreme Realm, but he was pulled away by a tentacle, which shows the strength of the monster that grows in the stone wall.

Langxin only hesitated slightly, and a third tentacle flew out of the stone crack, wrapped around his body, and dragged it in the direction of the stone crack.

Langxin injected true qi into the arm guard Tie Kai on both arms, urging the fire inscription in the arm guard.

His arms burned, and the surface of the Iron Arm Guard emitted a crimson glow, loosening the tentacles a little.

"Smack!"

The second tentacle pulled over and pumped it on Langxin's head, beating Langxin's face with blood, collapsing his cheekbones, bleeding from his mouth, and spitting out teeth from his mouth.

The second tentacle pulled over again, directly cracking Langxin's head open, becoming a blur of flesh and blood.

Langxin, who was still struggling, suddenly, stood still, and even the light on the arm guard Tiekai gradually disappeared and became dim.

Zhang Ruochen gasped when he saw Langxin's miserable appearance, if he didn't want to find a way to get out, his fate would definitely be worse than Langxin.

Two tentacles dragged Langxin's corpse into the crack in the stone.

Then, in the cracks of the stones, the sound of chewing "let's chirp" sounded.

Just now, he was a martial arts master in the Extreme Realm, and in an instant, he turned into a monster's blood food.

Cold sweat broke out on Zhang Ruochen's forehead, Langxin was already dead, did he have to become the blood food of that monster?

"There you have it!" Zhang Ruochen suddenly thought of a way.

Zhang Ruochen activated his true qi and injected the space-time spar to open the inner space of the space-time spar.

"Wow!"

The surface of the space-time spar flashed with white light, sucking Zhang Ruochen into the inner space.

Looking outside, Zhang Ruochen's body suddenly escaped from the black tentacles and disappeared, leaving only a white spar to fall to the ground.

As soon as the white spar landed, Zhang Ruochen jumped out of the spar again, picked up the white spar, and immediately fled into the distance.

"Whew!"

The monster in the crack in the stone let out a roaring sound, and at the same time stretched out three tentacles and attacked Zhang Ruochen.

Zhang Ruochen had already been tied up by the tentacles once, so he was naturally more cautious, and when the three tentacles stretched out, he changed his position four times in a row, turning into four phantoms, shuttling between the gaps in the tentacles, and dodging.

"Break it for me!"

Zhang Ruochen jumped into the air, took off, inspired the inscription in the snow dragon sword, waved his hands, and slashed down with a sword.

"Poof!"

A two-meter-long black tentacle was cut off by Zhang Ruochen and fell to the ground.

The monster was enraged by Zhang Ruochen and withdrew its three tentacles back into the stone crack, letting out a deafening howl.

"Boom!"

In the cracks in the stone, there was a cracking sound, knocking out fine cracks in the stone wall.

"Oh no! The stone wall is about to be broken, and that monster is about to run out!" Zhang Ruochen just turned around and wanted to escape, when suddenly, he saw a remnant of an animal skin on the ground.

The remnant picture fell from Langxin's body.

Zhang Ruochen picked up the remnant map, and immediately rushed down the stone steps, along the magma river, and fled into the distance.

"Boom!"

The stone wall more than 80 meters high collapsed, making a sound like a landslide and the ground cracked.

A huge black monster rushed out of the stone wall and chased after Zhang Ruochen who had escaped.

The black monster was more than thirty meters tall, its whole body was covered with a thick carapace, and its body had eight tentacles more than fifty meters long, and it crawled rapidly on the ground with an astonishing speed.

"It should be a brute beast bred underground, at least they are all third-order mid-level brute beasts, and maybe even third-order high-grade brute beasts. ”

According to Zhang Ruochen's judgment, the combat power of that black monster had reached at least the late stage of the Earth Extreme Realm, or even more powerful.

"Wings of the Wind. ”

Zhang Ruochen injected his true qi into the wings of the wind, and the two iron wings, which were originally only the size of a palm, turned into metal filaments under the urging of the true qi, and converged on Zhang Ruochen's back along Zhang Ruochen's arm, forming two light wings.

True Qi was running, and Zhang Ruochen rushed out at a speed of 100 meters per second like an arrow off the string.

The speed of that black monster was no slower than Zhang Ruochen's, and it chased closely behind, roaring from time to time, and spit out green poisonous mist from its mouth.

I don't know how far I fled, the road ahead was blocked, and two huge stone doors appeared.

On the top of the stone gate, four big characters are engraved: "Rock River Purgatory!"

The handwriting is mottled and seems to be hundreds of years old.

"There's no way!" Zhang Ruochen's face changed.

To the left of the stone gate is a large river of red magma, and to the right is a stone wall as hard as iron.

Zhang Ruochen stopped under the stone gate, and said secretly in his heart: "Could it be that this is the prison where the black market murderers are imprisoned?"

Zhang Ruochen was also thinking about whether to release the murderers in prison to resist the black monsters that caught up.

It's a pity that the two stone doors are arranged with sealing formations, and Zhang Ruochen doesn't know how to unlock the seals at all, so it is impossible to open the stone doors.

"Whew!"

The black monster chased after him, and when he saw Zhang Ruochen being blocked outside the stone gate, he let out an excited scream, his speed became faster, and he soon chased in front of Zhang Ruochen. In its opinion, Zhang Ruochen can only be slaughtered by him now.
