Soon, Cheng Qian found another hole in the rocks at the bottom of the river.

"That spiritual pressure seems to come from here, but why is it closer, this spiritual pressure is a little weak, and it doesn't look like the spiritual pressure of the Yuan Infant Stage. ”

Cheng Qian lingered in front of the entrance of the cave, looking at the entrance of the cave with flickering eyes, muttering to himself.

The entrance of the cave in front of Cheng Qian was several zhang large, and looking into the depths from the cave entrance, there seemed to be a faint blue light flickering.

After a little hesitation, Cheng Qian's body moved, and he was about to swim to the cave.

I saw that Cheng Qian was wrapped in a layer of cyan light, and this light mask slowly drifted towards the deep black hole on the wall.

When Cheng Qian just swam a few feet away from the entrance of the cave, he was stunned and couldn't help frowning.

I saw Cheng Qian raise his hand slightly, and a blue light rushed out of his sleeve robe and shot towards the hole.

Suddenly a strange scene appeared, a layer of light blue light curtain suddenly appeared at the entrance of the cave, blocking the blue light sent out by Cheng Gan, and then the blue light disappeared, and the light blue light curtain also disappeared slightly, disappeared without a trace, and returned to the original cave entrance, if it wasn't for Cheng Qian to see the light curtain with his own eyes, he didn't know that there was a hidden prohibition here.

Cheng Qian looked at the entrance of the cave in disbelief, he didn't feel that there was a ban here when he came here just now, just to test it for safety, but he didn't expect to really test a ban.

This forbidden method is a bit clever, so hidden, if Cheng Qian accidentally bumps into it, I don't know what will happen.

After staring at the entrance of the cave for a while, Cheng Gan flicked his right hand on his waist, and a jade slip emerged, and in an instant, Cheng Gan sank his divine sense into the jade slip.

After a while, Cheng Qian's face showed a look of surprise when he withdrew from his divine sense, and he put away the jade slip in his hand, his eyes narrowed slightly, staring at the hole in front of him.

I saw that with a flick of his waist with one hand, three spiritual lights suddenly rushed out, and I saw that those three spiritual lights appeared in front of Cheng Qian, revealing three array flags of different colors.

Cheng Gan waved his right hand forward, grabbed the three-pole array flag in his hand, he took a deep breath, and suddenly spit out the array flag in his hand, a stream of essence spewed out, only to see the three-pole array flag in his hand, and suddenly the spiritual light was released, Cheng Qian raised it with one hand, and the array flag turned into red, yellow and blue respectively, and the three spiritual lights shot out to the front of the hole.

At the same time, Cheng Gan's hands danced like butterflies wearing flowers, and he was still chanting this obscure mantra in his mouth.

"Disease"

I only heard Cheng Qian's soft voice, his dancing hands stopped, and a spiritual light shot out from his raised hand, hitting the three rays of red, yellow and blue.

Suddenly, the three spiritual lights shook, and they were horizontal in the form of horns, and with a quick flash, they were embedded in the stone wall at the entrance of the cave, just enclosing the entrance of the cave in a circle.

The red, yellow, and blue three-pole array flags each shot out a spiritual light, shooting at the opposing array flags, instantly docking into a triangle, and a three-color light curtain appeared in the center of the hole, wrapping the entire hole, and the three-color light curtain flashed, and a cone suddenly condensed from the center of the light curtain, and just condensed into a flash and shot towards the hole.

I saw that the conerate had just flashed to the entrance of the cave, and the light blue light curtain appeared again, and the conerate suddenly accelerated when it saw this, rushing towards the light curtain.

Sting

It was like the sound of clothes tearing, and I saw that the blue light curtain not only did not block the cone, but was torn out of a gap from the center.

Seeing this, Cheng Qian's figure immediately flashed, and without hesitation, he retracted into the crack, and quickly entered.

Cheng Qian, who retracted into the cave, was stunned, looked back at the three-color formation at the entrance of the cave, and showed a satisfied expression.

"Crystallization is blocked, and there is such a prohibition in the world. Cheng Qian looked at the hole behind him and said to himself slightly.

When Cheng Qian first tried out this prohibition at the entrance of the cave, he was puzzled, there was no flaw in this formation, not even a trace of spiritual power fluctuations, but Cheng Qian could clearly feel the spiritual pressure in the cave, so the prohibition at the entrance of the cave did not cover up the spiritual pressure inside, this technique is rare in the world of cultivating immortals, and it is not clear what danger it is, so Cheng Qian immediately took out the "Xuanxin True Experience" to check, not to mention that it was really found by Cheng Gan. ...,

According to the introduction of the jade jian, this prohibition is called the crystallization blocking curtain, which is a self-generated prohibition, Cheng Qian was a little puzzled when he saw this, and after entering this space, the illusion maze array was also self-generated, and here it was a self-generated, but what he said next solved Cheng Qian's confusion.

It is not so easy for this crystallization curtain to be produced by itself, the first is the crystal, the crystal described in the jade slip is called the blue killing crystal, if you encounter this crystal blocking curtain, there will inevitably be a blue killing crystal here, and this prohibition is produced by using the blue killing crystal as a power source.

Blue Killing Crystal is not a precious material, where there is this crystal, there must be a demon beast, and this demon beast is not an ordinary demon beast, the demon beast is a powerful dragon, named Blue Killing Water Jiao.

These crystals are all condensed from this blue killing water Jiao, and the dragons who have not opened their minds have one thing in common, that is, they like to collect shiny items, like to collect gold and silver treasures, as long as they are shining, they all like it, but the difference between the blue killing water Jiao is that it will not collect those shiny things, but refining the crystals by itself, this crystal is the blue killing crystal, which is the origin of the blue killing crystal.

In other words, where Cheng Qian is now, there must be a Blue Killing Water Jiao, this kind of Jiaolong is also quite rare in the immortal cultivation world, and it is also extremely powerful, but Cheng Qian does not know the details of the Blue Killing Water Jiao, because the records in "Xuan Xin Xin Experience" are basically the illustrated books of the formation, and there is no detail of this demon beast.

Cheng Qian was a little hesitant at the entrance of the cave just now, although the blue killing water Jiao is an ownerless thing, it must not be able to subdue the demon beast himself, I have heard my father say that all kinds of demon beasts in the immortal cultivation world before, but the dragon demon beast is the most difficult to surrender, the dragon is a branch of the real dragon, although the blood is not pure, but it is also quite arrogant, so to surrender him must be a person with strong magical powers.

However, Cheng Qian thought again, since he came, there was no reason to retreat, then it would not be himself, cultivating immortals was more particular about moving with his heart, although he didn't know if he could surrender this demon beast, but he also had to try his best, in Cheng Qian's mind, although this demon beast had the coercion of the Yuan Infant Period, but its coercion did not stimulate the killing array in this space, in Cheng Qian's opinion, this demon beast must be the same as the parasitic spirit beast on his body, all cultivated to fall, during the recovery period.

Thinking of this, Cheng Qian's body moved, the water pattern handkerchief flew out of his waist and turned into a light curtain to wrap him, his hands flashed with two cold rays, and the Wuji Sword and the Xuantie Heavy Sword both appeared in his hands, of course Cheng Qian, who knew what was in the cave, could not hide it, Jiao, there was a pressure when he heard the name, and he didn't dare to explain his life here.

After preparing a qiē, Cheng Qian boldly probed his divine sense into the cave, which was not big but was about ten zhang long from the sole of Cheng Qian's feet to the top of the cave, which was just enough to pass through a huge demon beast.

Cheng Qian, who was stretching his divine sense, suddenly raised his eyebrows, as if he had encountered something.

In the divine sense, Cheng Qian walked all the way and did not find anything strange and that Jiao, this hole does not know how deep, when Cheng Qian's divine sense probed more than ten zhang, he encountered resistance, as for what Cheng Qian is not easy to say, this resistance came out of thin air, so that Cheng Gan's divine sense can not take a step forward.

After a little hesitation, Cheng Qian stretched his brows, and slowly moved towards the cave with his twin swords.

As he slowly walked in, there were more and more blue rays in the cave, but he didn't know where the blue light came from, with these doubts, Cheng Qian moved his feet cautiously.

In an instant, Cheng Qian came to the place where the divine consciousness was isolated, in the deep and secluded cave, and he didn't see what was blocking it, so Cheng Qian mobilized the mana of his whole body, slowly injected his eyes, and used the spiritual vision technique to the extreme, looking into the distance. ...,

Cheng Qian didn't see anything, there was just a stone wall in front of him, and there seemed to be a corner, and the faint blue light was emitting from that corner.

He casually picked up a small pebble on the ground and threw it forward, the place that blocked Cheng Qian's divine sense, the small pebble passed through lightly, obviously after walking inside, his divine consciousness would be suppressed, which was quite unfavorable to Cheng Qian.

Cheng Qian touched his chin, his eyes narrowed slightly, stared at the cave for a long time, and muttered, "Since it is a ban, there are weaknesses." ”

Then Cheng Qian used the spiritual eye technique to the extreme, and looked around, not to mention that Cheng Qian really saw a strange thing.

On the stone wall not far away, there was a strange text, Cheng Qian stared at it for a long time, this text was a little familiar, but he still couldn't recognize what it was, and then Cheng Qian slowly walked towards the stone wall, and the more Cheng Qian looked at the text after entering, the more familiar it became.

"Demon Clan Text" Cheng Qian didn't know what he thought, and suddenly exclaimed.

Yes, this is the demon clan script, this kind of script Cheng Qian has seen on the Demon Spirit Island, and he doesn't know it, and then Cheng Qian's face showed a hint of joy.

I saw a purple light flash from Cheng Qian's fingertips, and he didn't enter the demon clan's text, and suddenly that text was shining.

Woo

A low humming sound came out, as if something had been turned off, and when he heard this, Cheng Qian's eyebrows moved, and he released his divine consciousness, as he expected, his divine consciousness did not easily probe in before receiving the barrier.

Then Cheng Qian did not hesitate, his body moved and walked towards the hole, and after turning a corner, Cheng Qian stopped, because he had reached the end of the hole at this time.

There are several stone gates at the end of this, and there are several demon characters written on each stone gate, although Cheng Qian doesn't know the meaning of these words, but he also guessed that Zhu Tianshen and the two said that this is the ancient cultivation of the cave, but there are stone gates here on behalf of Zhu Tianshen's words, the general cave is very simple, some prohibit some stone gates, these stone doors are unique things in the cave, spirit medicine room, spirit beast room, practice room, etc.

So it's not difficult for Cheng Qian to guess what is behind these stone gates, but these doors are all demon characters, which makes Cheng Qian wonder, could it be the ancient demon cultivation cave mansion?

In order to get in touch with his doubts, Cheng Qian did not hesitate, and used the same technique to inject demonic power into those words.

Bang

With a muffled sound, a stone door in front of Cheng Qian suddenly opened, and ten thousand blue rays rushed out.

"There are so many crystals," Cheng Qian shouted with a look of surprise on his face as he stood at the door and looked at the stone door that had just opened...... ，
