If you want to kill the other party, Cheng Qian also has another killer weapon, that is, to merge with the demon wolf, so that Xiuwei can reach the peak of the Dan period, but in this case, although he can kill the other party, but there is a time limit, and the time of a stick of incense can destroy the other party, but after it is destroyed, it is to face those prohibitions by himself.

What Cheng Qian is doing now is to use the other party as his own gun to open the way for himself.

The old man in the robe was puzzled by all his doubts, Cheng Qian leaked all his hole cards, and he really couldn't figure out why.

"Okay, the old man's condensing mirror can break many kinds of prohibitions, but it also consumes quite mana, at this time, we must first recover the mana" The old man asked with a hint of tentative tone, at this time, his mana is not much, and he can't take Cheng Qian in a short time, and he doesn't have the elixir like Cheng Qian's instant mana, so he can only endure it for a while.

"Hehe, fellow Daoists, please take care of yourself" Cheng Qian smiled slightly, and said like this.

Then the two hit it off, the old man took out the elixir, and after taking it, he slowly refined it, and the mana in his body grew like a tide, but it was not as full as instantly as Cheng Qian.

Cheng Qian also watched quietly, without the slightest sign of a sneak attack, even if the magic power was full, as long as he merged with the demon wolf, the other party would definitely be able to take it.

Although the old man was recovering his mana, he was also vigilant in his heart, and he was also guarding against Cheng Qian, lest he suddenly burst out and launch a sneak attack on him.

After a while, the mana of the old man in the Dao robe finally regained his saturation, and he raised his hand and swept out the condensing mirror again, and with a trembling spirit, the milky white pillar of light shot out with a bang, striking fiercely at the layer of light curtain.

"Cheng Daoyou, also come to help the old man, and strive to break it in the shortest possible time. ”

Cheng Qian didn't reply when he saw this, he raised his hand and flicked it, the blue light shone endlessly, and a cyan fairy sword floated out, and the aura on the surface was endless, and it seemed to be a little more powerful than ordinary magic weapons.

Then Cheng Qian's fingers stretched out, and a little forward, the fairy sword turned into a brilliant spiritual light, and it bombarded directly on the defensive light curtain.

Half an hour later, the layer of defense and prohibition collapsed, shattering like glass, and then a high temperature instantly swept the entire karst cave, under this high temperature, Cheng Qian's whole person seemed to be about to evaporate.

Even the old man felt a trace of discomfort, and his face showed a hint of sternness.

However, at this moment, the fire spirit bead in Cheng Gan's body seemed to be a little throbbing, if it wasn't for Cheng Gan deliberately suppressing it, I'm afraid it would have rushed out of the dantian, in the face of such a pure earth-centered fire vein, of course the fire spirit bead couldn't bear it, and wanted to rush out and enter the fire vein to bathe and nourish it.

With the shattering of the light curtain, the scene in front of him was revealed, no longer a magma, only to see that the scene opposite the magma was also clearly presented, it was not a dead end, there was a hole in the wall, and I didn't know where it led.

Seeing this, the old man in the Taoist robe was overjoyed, and his whole body was full of spirits, and he rushed towards the other side of the magma.

However, just as the old man's figure rushed into the sky above the magma, a sudden change occurred.

Poof

A muffled sound came out, and the magma that had been flowing quietly began to boil violently, and suddenly a giant dragon formed by condensation rushed out of the magma.

Oh

With a dragon roar, the dragon slammed into the old man in the robe above the magma with a hideous color.

"Hmph"

The old man seemed to have expected it, his body suddenly turned to the side, a large mouth of silver light flickered, and a silver fairy sword erupted from his mouth, with a majestic coercion to kill the lava dragon.

Cheng Qian, who had not moved, was about to fly away with the old man just now, but he felt that there was something wrong, so he had to wait for the old man to fly over first. ...,

Unexpectedly, there was really a change, which made him a little dumbfounded, and he was secretly happy in his heart, and it was right to leave this old man's life for the time being.

In an instant, the old man was entangled with the flame dragon, and then it had a bright light on the surface, but it had no intelligence, and he didn't know why there was such a strange dragon here.

The old man's magic weapon was naturally sharp, and he quickly cut the flame dragon into several pieces, and the broken body turned into fiery red lava again, falling into the magma, splashing out a trace of flame-like water.

Thundered

Then the magma began to shake violently, wave after wave on both sides, countless ripples rippling, lapping against the stone walls on both sides, splashing hot streams.

One after another, the red pillars of light erupted from them, and under the flow of flames on the surface of the pillars of light, they turned into several flame dragons in an instant, roaring towards the old man.

Seeing this, the old man did not hesitate, and a few traces of silver slashed in front of him, and the silver fairy sword flew wildly around, slaughtering these flame dragons fiercely.

"Being able to condense these dragons out of thin air, and being in the magma, I'm afraid it's a formation" Cheng Qian looked at the scene in front of him, a flash of inspiration flashed in his mind, and he said like this.

"Oh?" the old man was stunned when he heard this, he didn't even see the way out of the door, but this kid actually saw it: "You are still proficient in the way of formation?"

Cheng Qian can have such an experience, but Xuan Zhen's experience is indispensable, this kind of similar formation, I have seen several in the jade slip, this kind of formation attack, is not made of ordinary spiritual power, but uses the real natural attack to trigger, this is called a natural formation.

Using the original magma as a medium to launch an attack can be described as ingenious, and the natural formation is divided into two types, one is the innate formation and the other is the acquired formation.

The innate formation is formed by the natural elements between heaven and earth, which evolve on its own, but the acquired formation is the one in which the immortal cultivator exerts his magical power and turns the existing natural landscape into an attack formation, which is completely different.

"If Daoist friends want to break this formation, I'm afraid they need to destroy the entire Earth's Heart Fire Vein, so that they can break it" Cheng Gan's voice came out slowly, but Cheng Qian didn't say it all.

If this kind of formation wants to pass guò, there are still other ways, and there is also a way to crack it in Xuanzhen's heart.

"How is it possible, this Qinjialing, our Lei Li Sect will be used as a base in the future, how can it be possible to destroy such a good fire vein in the center of the earth," the old man in the Taoist robe said like this.

"Hehe, you should never think about it, but since you don't want to, then Cheng can only help you."

Cheng Qian showed a sinister smile, at this time the old man fell into the formation, it was the best time to kill him, although Cheng Qianxiang used him as a gunman, but the hidden place was too big, if he was not careful, he was afraid that he would capsize in the gutter, and the other party's cultivation was too much higher than him.

"What do you want to do" A trace of anger flashed on the face of the old man in the Taoist robe, this kid is playing yin.

Cheng Qian didn't reply, the condensed demonic qi in his body burst out, and soon the surface of his body was wrapped in a layer of purple mist, submerging his body in it, and soon a sky-rushing spiritual pressure rushed out from the purple mist...... ，
