Liu Cheng and Su Zhu did not expect that a mysterious man appeared at the critical moment and directly rescued Yuan Hao.

They looked at each other. The man in the black wind was Chen Kun. He was the only one with speed and power in Nanjing.

But what they didn't expect is that this guy's strength has improved.

When he was in Dingshan before, Chen Kun's strength was at most between that of Su Zhu. Even Liu Cheng could not win easily.

However, today, with his own strength, he even defeated Liu Cheng and Su Zhu at the same time. This strength is almost the same as the strength that Chen Kun showed when he was about to leave that day.

The fluctuation is obviously the degree of five grades.

Has this guy broken through to the five level?

Liu Cheng and Su Zhu both saw the shock in each other's eyes. If Chen Kun really broke through to the Wupin realm, they would have no hope.

Although the top level of the four grades is only a little different from the top level of the five grades, the strength gap between the two is very different.

Let alone Liu Cheng and Su Zhu, the two top four, even if it's another two or three, it's not necessarily the opponent of each other.

At this time, Liu Cheng said: "if he really reached that level, he would not have come and gone in a hurry just now."

Su Zhu nodded: "it's not bad, the master of that realm, there's almost no problem in taking us two!"

"Yes, I think Chen Kun also used some secret method to improve his strength," Liu Cheng said. "By the way, senior, what happened to the Su family's old master..."

Without waiting for Liu Cheng to finish, Su Zhu waved his hand and said with a smile, "in any change, there will inevitably be blood and sacrifice. I just hope my father's blood will not flow in vain!"

Liu Cheng nodded heavily: "master, don't worry, this blood debt will be paid by Su Zhu's blood!"

Su Zhu looked at him and said with a smile, "it's definitely a blessing for Nanjing city to have talents like you, and it's also a blessing for the whole metaphysical circle!"

Liu Cheng smiles and doesn't speak.

So they stood here. They looked at the tower in front of them and didn't know what to say for a moment.

The tower is seven stories high. The first and second floors are guarded by Yuanhao, but what's on the top five floors? Even Yuanhao doesn't know.

Immediately, Su Zhu's body flashed and flew straight to the third floor.

When Liu Cheng saw this, he followed closely.

They fell on the ground of the third floor one after another. Looking at the stone gate, they both felt a strong force condensing on the gate.

At this time, Su Zhu stretched out his hand and pressed it on the stone gate. He slowly pushed the pneumatic engine.

With a bang, the gas engine soared in an instant, but Shimen remained intact, while Su Zhu was pushed out by a strong force.

When Liu Cheng saw this, he was even more surprised. Is there anything strange on the stone gate?

Immediately, he also stepped forward and put his hand on the stone gate.

"Boom", just like Su Zhu, the air engine rioted by the way and attacked the stone gate. The next second, a huge force attacked him. Liu Cheng sank. He had seen Su Zhu before, so he was ready and urged the air engine again.

With the enhancement of Liu Cheng's hand Qi, the strength of this stone door is also increasing.

Liu Cheng's momentum is getting stronger and stronger. The whole person's hair is standing upright, which has obviously driven the air engine to the extreme. Su Zhu looks at Liu Cheng, especially feels Liu Cheng's momentum. He can't help but be surprised.

"This young man really has a good skill. He is young, and his cultivation has reached this level?" Su Zhu was amazed.

At this time, Liu Cheng has already run his own gas engine to the extreme, but the stone gate is still motionless. He suddenly mobilizes the mysterious energy in the air sea.

Black nightmare ice crystal!

In a flash, I saw a black light flickering on his right palm. Just in the blink of an eye, a black ice crystal appeared in the place covered by his palm.

That layer of black ice began to slowly extend, originally just slap big place, but with Liu Cheng's strength, gradually bigger and bigger, began to completely cover the whole stone gate.

Liu Cheng only felt that the air engine in the air sea began to feel exhausted. Since he had the air engine, this feeling rarely appeared.

The gas engine dried up, just like the water in the well suddenly dried up.

In the previous two times, it seems that Liu Cheng had no choice but to use the dragon's back sword.

However, Longji sword is a magic weapon in the world after all. It consumes a lot of Qi, which is normal.

To Liu Cheng's surprise, this black nightmare ice crystal consumes so much gas.

Think of here, Liu Cheng heart a Lin, and then continue to crazy urge air sea, there are only a few gas engine.

"Boom!"

With a bang, an explosive force came from the stone gate and directly pulled Liu Chengzhen out. The latter suddenly retreated seven or eight steps, until he felt a gentle force on his back."Thank you, master!" Liu Cheng said in a voice.

Su Zhu withdrew his right palm, slightly surprised, "what's your secret skill?"

Liu Cheng laughs and talks about the fight with Yuan Hao.

After hearing this, Su Zhu frowned slightly: "Yuanhao, although I haven't dealt with him before, I've also heard his reputation. It seems that what he practices is a secret skill called black nightmare ice magic formula. This secret skill is a secret skill passed down from Beihai. It seems that when cultivated to a certain extent, it will be transformed into black nightmare ice crystal, which can devour the Qi of human body, It's very terrible. It seems that Yuanhao's cultivation has reached a critical moment. I didn't expect that you robbed him of the fruits of victory! "

Liu Cheng suddenly realized that this black nightmare ice crystal was actually this kind of thing.

"Haha, it's human evils," Liu Cheng said with a sneer. "If Yuan Hao helps tyranny, if he turns into a black nightmare ice crystal, I'm afraid we'll have to deal with it. Now, he's almost half useless!"

Su Zhu nodded: "Yuanhao's lower body has been completely destroyed by me. It's almost by virtue of his strong horizontal Qi that he can survive. Even if Chen Kun saves him, it doesn't have any effect."

"This is also the most puzzling thing for me," Liu Cheng said. "Yuanhao is half useless. Why does Chen Kun not hesitate to use secret arts to improve his strength and save him? What else does Chen Kun have in mind?"

Su Zhu frowned slightly and said, "this man has a deep mind. It can be seen just by his layout for so many years. Maybe he really has any other plans."

After a pause, Liu Cheng said: "master, this tower can't be opened at present. Why don't we go to other places and gather some experts first, or we won't be Chen Kun's rivals just by our own strength!"

"That makes sense. Let's go!" Su Zhu nodded.
