The iron-backed wolf king's body was like electricity, and his sharp fangs slammed towards Sun Cheng.

Sun Cheng leaned back against the giant tree, and the true yuan in his body was frantically used through the demon slayer knife, and he actually resisted his powerful attack.

At this moment, on the two fangs of the iron-backed blue wolf king, a cyan light suddenly flashed at the same time.

"This ......"

Sun Cheng's face changed, and the blood-colored sword on the demon slayer knife exploded. With this force, his whole body leaped upwards violently.

Almost at the same time, the cyan light on the fangs of the iron-backed blue wolf king also turned into two cyan light knives, shooting towards Sun Cheng.

Poof, poof!

There were two sounds in a row, and the two cyan light knives turned out to be one left and one right, passing past Sun Cheng's chest and back, and two pieces of flesh and blood flew away.

It's just that this time, Sun Cheng has already been hit hard.

Fortunately, Sun Cheng didn't realize it in advance and responded in time, otherwise he would not have been injured, but would have died.

"This turned out to be a magical power. ”

At this moment, Sun Cheng stood on top of the thick branches, completely ignoring his injuries, with a solemn look on his face.

The demon beasts of the Mortal Realm have already begun to conceive demon power in their bodies, but ordinary demon beasts cannot make good use of this power, and can only use it to strengthen their bodies, with faster speed and stronger strength.

However, when they reached the fourth level of mortal transformation, the demon beasts began to reveal that they were different, and the demonic power in their bodies was conceived enough to manifest and show their supernatural powers.

And this is one of the fundamental reasons why monsters can compete with humans, and even overwhelm humans.

This iron-backed blue wolf king actually broke through in the battle, and accidentally stimulated the magic power - the cyan light knife, and obviously one foot had already entered the ranks of the demon beasts of the fourth level of transformation.

Sun Cheng knew that he had to fight quickly.

Otherwise, when this beast accumulates in the battle, becomes more and more proficient in the control of demonic powers, and truly breaks through to the fourth-level demon beast, it is really possible that he will die at that time.

Immediately, Sun Cheng's face froze and he made up his mind.

The true yuan in the body no longer has reservations, and it bursts out frantically, and the demon slayer knife in his hand is slashed out one after another, almost at the same time, he used three moves "Tairi Knife Technique First Style".

This is the ultimate that Sun Cheng can do.

The extremely powerful True Yuan actually suppressed the blood dragon pattern in the Demon Slayer Knife, and no longer appeared in a blood-colored sword, but drew three golden sword rays more than one meter long in the void.

The three golden swords one after the other, but at the same time they converged on one pole and evolved into a small golden sun.

Suddenly, within a radius of 100 meters, it was illuminated.

The little sun formed in mid-air, and then crushed towards the iron-backed blue wolf king.

This is the first style of the real Da Ri Sword Technique, "one day in the air", faintly revealing a trace of the domineering and strong of the superb martial arts.

Sun Cheng had never used it before, just because this was the ultimate trick, and it must not be used until the last moment. Otherwise, once it is used, it means that the true essence and qi and blood in the body will be drained, leaving no trace, and there is no strength to move.

Until he fully recovers, he has no power to resist even the smallest threat. I'm afraid that at this time, even a child can easily kill Sun Cheng.

Rumble!

In the face of this unrivaled domineering trick, the iron-backed blue wolf king couldn't even resist, and was directly suppressed, and his flesh and blood were burned in a blur.

Immediately, Sun Cheng's strength dispersed and he sat down on the branch.

Fortunately, when the wolves saw that the wolf king was killed in battle, they all scattered and fled without restraint, and did not come to attack Sun Cheng, otherwise he would really have to die in the wolf's mouth.

The demon slayer knife was detached from Sun Cheng's hand, turned into a red light, and inserted it into the corpse of the iron-backed blue wolf king, absorbing the blood of the demon beast essence, and began to advance towards the dragon pattern divine weapon of the first and second ranks.

......

Sun Chengpan sat on the dense branches of the trees and meditated and breathed, and several hours passed in a row, until the scorching sun was in the sky and the woods began to heat up, and he barely recovered.

Fortunately, there was the momentum of the iron-backed blue wolf king before his death, and no other demon beasts came to disturb him during this period, so that Sun Cheng was lucky to get through the most difficult period.

Sure enough, combat is the best way to cultivate.

After the extreme battle just now, Sun Cheng found that the true yuan condensed in his body again was much more condensed than before, and he was faintly moving towards the cultivation of the Yuan Martial Realm.

Immediately turned over and jumped off the branch, a true yuan was thrown out, and the demon slayer knife was rolled upside down and held it in his hand.

At this time, the demon slayer knife has successfully advanced to become a dragon pattern divine weapon of the first rank and second grade.

A whole head of demon beast essence blood at the peak of the third level of transformation is far more powerful than the essence blood of ten demon beasts at the second level of transformation, and the advancement of the demon slayer knife was originally expected.

In addition, Sun Cheng also put away the pair of sharp fangs, this thing is the most precious thing in the body of the iron-backed blue wolf king, take it back and sell it, it can be exchanged for hundreds of gold, which is also a huge amount of money for him who is extremely short of money.

The battle with the iron-backed wolf king was extremely dangerous, but he didn't die. Fortunately, the overall harvest was quite rich, and Sun Cheng did not take risks in vain, and Sun Cheng's mood was much more relaxed.

After cleaning up, Sun Chengcheng continued towards the Blackwater Dungeon.

The last section of two or three miles, under Sun Cheng's careful evasion, did not encounter a demon beast attack.

Walking through the primeval jungle, Sun Cheng felt that the vision in front of him suddenly opened up.

What comes into view is a large black lake with a radius of several hundred meters.

Sun Cheng obviously felt that the wind was howling on the lake at this time, but when the wind blew through the lake, it only brought a slight ripple.

When I looked at it, I couldn't find a single living thing, either by the lake or in the air above the lake. The whole lake was as if it were dead, without any life.

And in the middle of the lake, there is a small island with a radius of 100 meters.

Seeing this terrain, Sun Cheng's face changed, and he became very ugly. He never thought that this black water dungeon, which had been legendary in Qingyang Town, would really be located in a black water.

Originally, his plan was to wait for the Blackwater Dungeon to sneak in it and rescue his father directly, thinking that with his means, he could avoid a lot of trouble.

But with this black water in the way, it is almost impossible to sneak in.

This black water is not an ordinary lake, but the manifestation of the Netherworld Yellow Spring, which is stagnant water.

If human beings enter this stagnant water, they can turn you into a pile of bones in a moment, and even if your soul swims across, you will drown in the bottom of the water, and you will never be able to escape.

If you want to cross this lake, you either have a peerless cultivation like Emperor Wu in the previous life, or you can wade through the water with the help of a boat built by a thousand-year-old thunderwood.

At this time, Sun Cheng finally understood that it was no wonder that the previous mayors would rather face the threat of various demon beasts and build this black water dungeon ten miles away from Qingyang Town.

If the prisoners are locked up here, it will be impossible to escape, and there will be almost no accidents.

What's more, according to the news heard by the predecessor "Sun Cheng", the person sent by the Li family to guard this black water dungeon was a great master of the eightfold cultivation of the Yuan Martial Realm.

You must know that the owner of the Meng's Martial Arts Pavilion is only the eighth-fold cultivation of the Yuan Martial Realm. A master of this level is a giant in Qingyang Town.

Even if Sun Cheng found the thousand-year-old thunderwood boat, it was clear at a glance on this endless lake, and he couldn't hide it at all. Once you land on the island, you will face the thunderous blow of the eightfold master of the Yuanwu Realm, and you will definitely die.
