In the Illusory Void Ring, Yang Cheng was telling Yu Jia about Danhuo, although he was not an alchemist in his previous life, he still knew some basic things.

"As far as I know, there are three kinds of Danhuo, the first is the spiritual fire of heaven and earth, this kind of flame is usually bred by heaven and earth when it is first formed, followed by beast fire, just listen to the name, it is from beasts, such as the purple fire of Zifeng, and the golden flame of Xiaojin, these all belong to beast fire, the third flame, the practice fire, is also the weakest flame, it belongs to the flame condensed by the cultivator himself, and it should not be used as a means of attack, although this is the best controlled flame, which is very suitable for junior alchemists, or refiners. ”

After Yang Cheng finished speaking, he paused, first let Yu Jia digest this knowledge, and seeing that she had almost digested it, he said: "As a beginner, I suggest that you start by practicing fire, it is not as manic as beast fire, and it is easier to control, which is very suitable for you now." ”

"But how do I condense the fire practice?" Yu Jia scratched her head and asked puzzled.

"Isn't it in the Book of Dan Dao?"

"Oh, then I'll see. Yu Jia grinned, and only then did he remember the book of Dan Dao in his mind when he heard Yang Cheng's reminder.

Yang Cheng shook his head and smiled, "This little girl." ”

Yu Jia closed her eyes lightly, her divine sense turned into an invisible big hand in her mind, and she opened the Dan Dao branch book in her mind, just for a moment, she opened her eyes again, and her eyes flashed with excitement, "I see!"

"Found it?" Yang Cheng asked.

"Well, I'm going to condense!" Yu Jia said excitedly to sit cross-legged.

"Wait, let's go to the Chaos Orb. Yang Cheng stretched out his hand and grabbed Yu Jia.

Yu Jia glanced at Yang Cheng in surprise, but she didn't ask much, just nodded her head, and the next moment she and Yang Cheng disappeared into the Illusory Ring and entered the Chaos Bead.

The reason why Yang Cheng asked Yu Jia to stop and go to the Chaos Bead was because he faintly felt that going to the Chaos Bead to condense and practice fire might have something other than that.

After Yu Jia entered the Chaos Bead, he sat directly on the ground with his knees crossed, and began to condense the flames according to the words of the Book of Dan Dao.

Yang Cheng didn't go far, and sat down not far from Yu Jia.

Yu Jia mobilized the true qi in her body, and slowly flowed in her body along a strange route of veins, and with the loss of time, the true qi slowly formed a "yin" and "fire" in her body.

These two words appear and disappear in her body, alternately disappearing, and are extremely mysterious.

Yang Cheng found that Yu Jia's face seemed to be a little wrong, but he didn't take it to heart, thinking that this was a normal performance when condensing and practicing fire.

Time passed minute by minute, and suddenly the word "Yin Fire" in Yu Jia's body appeared at the same time, and the next moment, it suddenly stopped, not disappearing alternately, and at this time, the ground of the Chaos Bead cracked one after another, and it seemed that there was a danger of subsidence.

Yang Cheng couldn't help but be shocked when he saw this, but he didn't find any danger when he sensed it carefully, his brows furrowed, and he just wanted to stand up and wake up Yu Jia, but at this moment, a change protruded.

I saw that there were repeated black flames rising from the cracks on the ground, and the next moment, a pillar of black flames rose into the sky, directly devouring the two of them.

The strange thing is that after the black flame submerged the figures of the two, the ground was no longer cracking, and slowly closed and returned to its original state.

Yang Cheng stood in the black flame, and did not feel the burning feeling, but a faint coldness, but it was not a natural coldness, this feeling you can't describe in words, just like the yin wind hit, making you unconsciously have your hairs standing on end, and it is as if this chill rises from the depths of your heart, not from the outside world.

Yang Cheng frowned, maybe it was because of his true qi, he didn't like this feeling very much, and looked at Yu Jia, she was not in any big trouble, she was still sitting there with her eyes closed, but there were black flames around her

Yang Cheng breathed a sigh of relief and muttered in a low voice, "What kind of flame is this, the movement is inevitably too big, right?" In his previous life, he had never seen an alchemist or a refiner condense and practice fire, so he didn't feel that there was anything wrong.

Seeing that there was nothing to do with him here, he was about to step out of the range of the black flames, but before he could move, his face changed.

The flames around Yang Cheng's body seemed to sense something, and suddenly they tumbled, and then turned into wisps of tiny flames and entered the veins of his body.

Yang Cheng only felt chills all over his body, and this feeling spread to all parts of his body with great speed, and he hurriedly used the true qi in his body to resist the invasion of black flames.

However, the true qi did not have the slightest effect on the black flame, on the contrary, as long as the true qi encountered the black flame, it disappeared like an ice disintegrate, not only that, but the true qi seemed to enhance the power of the black flame, making it more and more turbulent in Yang Cheng's body, and the speed of flowing in the veins was also much faster.

Yang Cheng was shocked but not confused, he responded calmly, he controlled his true qi, and gradually slowed down the speed of flowing towards the black flame, but as time passed, not only did the speed not slow down, but there seemed to be signs of acceleration.

Not good!

Yang Cheng screamed in his heart, because the true qi in his body seemed to be showing signs of getting out of control, and the flames outside were still drilling inside.

He wanted to launch a thousand steps out of the black flame range, but his feet seemed to be adsorbed by the pillar, and he couldn't move half a step.

Now Yang Chengke was a little anxious, the true qi in his body was becoming more and more difficult to control, and the speed of flowing towards the black flame was also getting faster and faster.

"Looks like I have to get out. ”

He whispered to himself as his mind moved, wanting to leave the Chaos Orb.

But what surprised and puzzled Yang Cheng was that under the activation of his own thoughts, there was no movement at all, as if he had lost contact with him, his face instantly became a little ugly, he looked at the black flames around him, and secretly thought in his heart: What are these black flames? Do you want to wake up Yu Jia? But if you wake her up, will there be any danger?

Yang Cheng turned his head and looked at Yu Jia, who was completely shrouded in black flames, and still shook his head, forget it, I'll try to run the exercises first, and take a look, can I slow down the speed at which the black flames devour true qi, thinking of this, he just stood like this, directly running the part of the Chaos Dual Cultivation Technique that belonged to him.

Time passed minute by minute, and Yang Cheng gradually entered a realm of selflessness while resisting the black fire.

The repeated black flames didn't seem to want to give up on Yang Cheng, and they became more and more ferocious eroding his body and the true qi in his body.

However, the strange thing is that Yang Cheng, with the assistance of the exercises, gradually formed a very flat posture with the black flame, although the black flame was violent, it could not break through Yang Cheng's dantian qi sea, as well as his mind.

But as time passed, the black flames in Yang Cheng's body were accumulating more and more, and this balance was gradually broken, and a faint layer of black ice ballast appeared on his bare skin, and his consciousness was blurring little by little.

Yu Jia was also immersed in the artistic conception of his own condensation and fire practice, and he was unaware of everything in the outside world.

Time flies quickly, the day has passed in the Chaos Bead, Yu Jia is still not awake, and looking at Yang Cheng, his figure has been replaced by a black crystal, and the strange thing is that there are many black flames beating in the black crystal.

"No, I can't hold on anymore. ”

"No, Yang Cheng, you have to hold on. ”

Two faint thoughts were intertwined and collided in Yang Cheng's mind, and it was not an exaggeration to say that the situation in his body was very bad now.

In addition to the upper dantian, the rest of the tendons and veins in the body were covered with a layer of faint black flames, fortunately, the destructiveness of these black flames to the flesh was not very great, otherwise even if Yang Cheng did not die, the tendons and veins would turn into nothingness, so that the cultivation would be pure and ruined, and he would not be allowed to cultivate for the rest of his life······
