"Okay, the next thing is Ning Dan. The liquid medicine should be balanced, and the liquid medicine must be stable when it is fused, and it will fluctuate but will not cause harm after the fusion is successful. After fusion, pay attention to the temperature, and the temperature must be balanced to reach the inside and outside of the elixir. Receiving Dan must be fast, and there is also the need to be calm. ”

Xiao Bai glanced at Cheng Tian helplessly, and then taught Cheng Tian some techniques of alchemy and pill collection, these skills seem to be very simple, but the actual operation can make those who consider themselves geniuses understand for a month or even a year, simple words do not mean that the actual operation will be simple, even the grandmaster of alchemy can only achieve this step of balance. Alchemy also needs soul power, soul power can be said to be one's own soul, soul as a means of alchemy can be said to be the best, use soul power to catch every aspect of the elixir, even if there is a deficiency, you can find it at the first time.

And soul power can be said to be something close to fiction, it is not energy but like energy. It can control things but not touch them, it can control the human spirit but it cannot resist the human will, it is close to an electric wave or an energy that cannot be touched. Cheng Tian still doesn't know what the soul is, from the earth's technology, he can understand that the soul is a kind of energy and a kind of brain wave, but here, people everywhere can use soul power and they don't die.

And Xiaobai's explanation to Cheng Tian is that the human brain will produce a strange power because of people's emotions, and this power will not disappear, and this power is like gas, after gathering and forming in the human brain, it will become a power that can kill millions of enemies with one thought. This power can be said to be a spiritual power or a human brain, and this power is controlled by people's emotions, and if people have resentment, this power will become extremely terrifying.

If human beings die in resentment, this energy in the body will form an energy that is changed by resentment, and this energy is often for a purpose, and this purpose cannot be dissipated if it is not accomplished. And this power will be obliterated by someone's spiritual will, and the strongest thing about a person is the spiritual soul and will. If the will is strong enough and the spirit is focused enough, the brain can produce a power against the soul, and what the soul is formed is mainly because of the human heart.

"Uh, okay, I'll try. ”

Cheng Tian sighed, and then began to try.

He put his hands on the furnace, then poured the liquid that had been refined into the furnace and surrounded it by flames. Many medicinal liquids moved in the Dan furnace, but the medicinal liquids did not touch a certain medicinal liquid, and Cheng Tian used his soul power to compress those medicinal liquids together. The soul power surged towards those medicinal liquids, and Cheng Tian could feel those essences in the medicinal liquids. The liquid medicine was all pressed together, and the liquid medicine pressed together suddenly emitted a fluctuation, which spread like a bell, and the fluctuation of the liquid medicine was similar to the shock wave generated by an explosion, and Cheng Tian's clothes were blown by these fluctuating impacts.

"It's such a strong impact, it seems that it is not easy for the liquid medicine to be fused together. ”

Feeling the fluctuations emitted by those medicinal liquids, Cheng Tian's body churned. He felt his blood slow under the influence of those fluctuations, and his meridians seemed to be clogged.

"Of course, this fluctuation is called Dan pressure. Dan pressure can't be divine, but it doesn't hurt people. As long as you stabilize your mind, you will be fine, all you have to do is focus on the elixir. ”

Xiaobai's voice appeared in Cheng Tian's mind, and Cheng Tian struck a spirit. He immediately did what Xiaobai said, kept his mind, and focused on the elixir. The influence of those pill pressures slowly disappeared, and the pills slowly fused with Cheng Tian's intentions, Cheng Tian's vitality increased, and the temperature of the flame immediately increased. The elixir became crystal clear under the roasting of the flames, but just when Cheng Tian thought that the fusion was successful, the prototype of the elixir suddenly exploded.

"Well, the vitality is insufficient. ”

Xiaobai suddenly said a word, Cheng Tian suddenly realized something after hearing it, and then he was affected by the shock wave of this explosion, and the whole person bounced off a meter directly. The liquid medicine flew around in an instant, and the fragrance of a liquid medicine appeared in the entire cave. Cheng Tian sat up, looked at the situation around him, and then he fell down.

"It seems that the alchemy has used up his vitality, and yes, he didn't have a good rest when he was refining the medicinal liquid before. The vitality also returned to the appearance of seven tenths, and the lack of vitality led to this Dan explosion. ”

Xiaobai flew to Cheng Tian's side, and then carefully observed the situation of the Dan furnace, fortunately, the Dan furnace was okay and could continue to be used. And Cheng Tian fainted because of the exhaustion of vitality, and Xiaobai smiled and disappeared.

Time passed slowly, and more than ten hours passed. Outside, the sun was setting, but now it's sunrise in the east. Cheng Tian's eyes opened slightly, and he sat up slowly with a tired face, and at this moment he looked ahead as if he was stupid. Then, as if realizing something, he immediately looked at the Dan furnace, and there was nothing in the Dan furnace, not even the rudiments of the elixir, which made him deeply shocked.

"What's the matter, my elixir. ”

Cheng Tian has only one thought at this moment, which is to go crazy.

"You don't have enough energy, the elixir has exploded. ”

Xiaobai's simple words made Cheng Tian feel stunned, and he thought about it carefully. It was indeed the reason for the lack of vitality, when he was refining the pill, he suddenly felt a pain in his abdomen, at first he thought it was a stomachache and ignored it, but as time passed, he found that it didn't seem to be a stomach pain, and his vitality seemed to be limited by something. Then his vitality suddenly became unusable, and when he tried to run it again, his eyes went black and fainted.

"I don't have a shortage of vitality, I've been refining medicinal liquids before. ”

Cheng Tian thought that his vitality was not so small, and he realized something as soon as he said it.

"Looks like you get it, you're too anxious. After refining the medicinal liquid, if you directly refine the pill without resting, of course, you will not have enough vitality. I can't imagine that your IQ is so high, I can't even describe your IQ. ”

Xiao Bai smiled with a flirtatious look, Cheng Tian looked embarrassed, only at this moment he wanted to kill Xiao Bai the most.
