Chen Xuan glanced around, and quickly changed a passage to enter, he knew that most of these passages were manned, but the Infinite Forging Soul Crystal he was looking for was in one of these passages, so he was still impatient to look for them one after another.

In addition to finding hundreds of fire crystals in the first passage, in the second passage, he saw two monks fighting, as if they were fighting over something. In the third passage, Chen Xuan saw a huge waterhole, and there were three monks staring at the edge of the waterhole.

Because these things were not very attractive to Chen Xuan, so soon, Chen Xuan entered the sixth passage, which happened to be blocked by a huge door, and judging from the situation around this stone gate, someone had attacked here. It should have felt that the attack had no effect on the stone gate, so he retreated.

Chen Xuan landed on the stone door and happened to see a keyhole. Chen Xuan didn't think about it at all, he directly grabbed the key and sent it into the keyhole of the stone door.

The key was extremely well matched into the keyhole, Chen Xuan twisted slightly, and the stone door made a rattling sound and slowly opened.

An extremely cold aura seeped in, and Chen Xuan's divine sense swept in, leaving only a white expanse. The divine sense scanned about a thousand meters, and just in time to find that the two monks had already walked in cautiously.

Chen Xuan didn't have the heart to talk to them, he took out the key, and his figure flashed into the extremely thick stone gate.

Soon, Chen Xuan discovered through his divine sense that there was a faint entrance in the main hall, as if it was an entrance to the basement.

Still without any hesitation, his figure flashed directly, directly entered the entrance to the basement, and landed on the ice steps.

An extremely cold cold extended over, making Chen Xuan feel cold slightly, but just by running the exercises, that cold disappeared.

Continuing to walk down the ice steps, it was getting colder and colder below, and even Chen Xuan's physique felt the cold. However, it was this feeling of extreme cold that made Chen Xuan more and more excited, which was enough to show that this might be the location of the immeasurable forging soul crystal in the original book.

After walking dozens of ice steps, the feeling of extreme cold instantly enveloped Chen Xuan's body, making Chen Xuan's figure stagnate, but after running the exercises again, that cold feeling disappeared again.

"Click......" At this moment, Chen Xuan seemed to have stepped on something, and there was a click.

Almost at the same time, a bright stone was thrown by the people above. The Bright Stone didn't seem to work in the misty space outside, but outside of this ice step, it was clear what was going on below.

"It turned out to be his ......" One of the male cultivators of the two, after seeing that it was Chen Xuan, his body was stagnant, and a heart of fear instantly enveloped his whole body.

He knew how terrifying Chen Xuan was, and he suppressed the powerhouse of the Yuan Dan Realm with one finger. Now that he has disturbed Chen Xuan, he doesn't know if he will be crushed to death.

However, at this moment, he exclaimed excitedly, "Down here is the Infinite Forging Soul Crystal......

"Immeasurable Forging Soul Crystal?" Chen Xuan frowned, although he did want to find the Infinite Forging Soul Crystal, but in fact, he hadn't seen it, so he didn't know what the Infinite Forging Soul Crystal looked like.

Now that he heard the Infinite Forging Soul Crystal, Chen Xuan's heart moved, and he jumped down. The height of dozens of zhang did not affect Chen Xuan in the slightest.

However, at this moment, the cold qi around him, like a fierce beast, instantly enveloped his whole body, and every trace of cold qi was in the bone marrow, even if Chen Xuan wanted to use the exercises to resist, there was no way.

At this moment, the blood was gradually frozen, and the skin on his hands was changing color and becoming pale at a speed visible to the naked eye, and it might only take a while for his body to be completely frozen, and then one day, he was blown by the wind, turned into ice slag, and disappeared without a trace.

It seemed that something was not right, and the male cultivator quickly wanted to escape, but the extremely cold air instantly froze him, and the other female cultivator also grabbed it casually while the male cultivator was speaking, and then because of the extreme cold, he couldn't make a soft reaction, and the next moment the two rolled down like ice balls.

Chen Xuan had no time to care about the two of them, his consciousness gradually blurred, he felt that his soul was about to leave his body, but there seemed to be something blocking him, making him unable to leave.

Can't die, absolutely can't die. He still has to save Yan'er, he can't die here. It seemed to be a return to the light, and it also seemed to stimulate the potential, Chen Xuan instantly thought of the fire crystal he had obtained before.

Regardless of whether the fire crystal could withstand the extreme cold, but as long as there was a chance, he could not give up. Moreover, he also has the Fire Sword Technique in the Three-Element Sword Technique, if he can successfully cultivate, maybe there will be a chance.

Quickly picked up the fire spar placed in the mixed element bead, and then ran the fire sword technique of the three-element sword technique. In just one Zhou Tian, a scorching flame burning sensation rose in Chen Xuan's dantian, and then instantly spread to the meridians of his whole body.

The scorching and terrifying burning, coupled with the extremely rich fire crystal, instantly ignited Chen Xuan's body, gradually burning from the meridians to his bone marrow, and from his bone marrow to his flesh.

The terrifying heat from the inside out, the terrifying cold as the outside, collided together. A strange balance was formed, and slowly Chen Xuan's body surface began to evaporate mist, his hands slowly regained their softness, and his body gradually regained consciousness.

That kind of hot and cold torment made Chen Xuan feel an indescribable pain. However, Chen Xuan had a little more surprise in his heart, and his physique seemed to be slowly strengthening.

The chill around him had gradually faded, and Chen Xuan had regained his former vitality. I don't know if it really stimulated Chen Xuan's potential, or because of the fire crystal, it only took a week or so to cultivate the fire sword technique to perfection.

Of course, it's not just the Fire Sword Technique, his current cultivation has broken through to the seventh layer of the Golden Pill Stage, and it is obvious that the reason for this breakthrough is because the aura of the fire crystal is too strong.

After packing up the remaining fire crystals, Chen Xuan took a look at the surrounding situation.

However, just a few minutes later, the surrounding chill became more and more intense, and it was estimated that in a minute or so, Chen Xuan would freeze like he had just now.

Chen Xuan didn't dare to hesitate for a moment, he quickly looked at the immeasurable forging soul crystal that the male cultivator had said before. I don't know what it looks like, but it contains a lot of vitality, and it's a treasure anyway.

As for the monks, one man and one woman, they had already been frozen into ice, and they could no longer die. Besides, even if he didn't die, Chen Xuan wouldn't waste time, his own life was in danger, how could he control them.

Quickly pick the two ice flowers together with the half-foot-long rhizome. He turned around and quickly rushed up the ice steps.

A minute later, Chen Xuan stood in the original hall again. He looked at the ice stairs that led below, and this time he almost died below.
