"Since Mr. needs the Longquan Sword Spectrum, the little girl promised Mr. as the person in charge of the Longquan Sword that after the gentleman finishes treating me, the little girl is willing to accompany Mr. to practice the Longquan Sword Spectrum together."

Bai Luochen's cheeks flushed with a faint flush, and her voice was a little more coquettish, but Zhang Yuwei didn't see what Bai Luochen meant, seeing that Bai Luochen agreed, Zhang Yuwei stood up and walked towards the place where the medicinal materials were settled, and about ten minutes later, Zhang Yuwei came back again, still holding some medicinal materials in his arms.

"Your meridians are already very fragile, if you want to heal them without harming them, direct detoxification is not possible"

Zhang Yuwei nodded towards the Danyang Hall on the side, and he said as he walked.

"Next, I want to refine a pill, its name is Yin and Yang Guiyi Dan, which is mainly used to regulate the power of the yin element and the power of the yang element in the body, and now the yin and yang in your body are uneven, because of the conflict between the power of the two elements, so the poison will deepen day by day."

Due to the Yin and Yang Returning to One Dan is a fourth-order intermediate pill, Zhang Yu is not good at refining in public, so he has to borrow the Danyang Palace, at this time in the Danyang Palace, there are almost no people, most of the people are concentrated outside the Danyang Hall waiting for the settlement of the first level of the Dan Hui, Zhang Yuwei sat in the center of the hall, he made a furnace in the void, and put the medicinal materials taken from the settlement medicinal materials into the flame Dan furnace.

Su Miaoyan didn't follow Zhang Yuwei, she had been helping Zhang Yuwei pay attention to the situation of the first level of the Danhui, and she was still waiting for Yu Ji and Xiang Yu, what made her strange was that it had been a day and a night, Yu Ji and Xiang Yu had not yet arrived, and Nanxun Zhenren had disappeared, Su Miaoyan was faintly uneasy in her heart, but she did not think about this, but focused on the settlement of the first level.

Bai Luochen followed Zhang Yuwei into the Danyang Palace, although she knew that it was very rude to disturb an alchemist to conduct alchemy, but she still couldn't help it, after all, Zhang Yuwei was her only hope, Zhang Yuwei felt that it was nothing, after all, it was just a low-level pill, if it was like a ninth-order pill or a ground-level pill, Zhang Yuwei would definitely put the alchemy to death and ban it, and would not let anyone enter and leave at will.

The difficulty of Yin and Yang is not in the refining of medicinal materials, because this kind of elixir is mainly used to reconcile the power of the yin element and the power of the yang element, so even if the medicinal materials are burned, it is fine, its difficulty lies in how to stabilize the elixir before becoming a pill, because the power of the yin element and the power of the yang element exist in a pill at the same time, there will be a violent reaction, and if you are not careful, the pill will burst, and therefore, Zhang Yu made two protective films for the power of his yin element and the power of the yang element, and wrapped them on the medicinal materials. He planned to refine the elixir directly under his protective film.

I saw that the medicinal materials were slowly divided into two piles in the protective film, one pile was floating in the yin element protective film, and the other was floating in the yang element protective film, because of the existence of the protective film, the rate of fusion of the two piles of medicinal materials was very gentle, although the formation of the pill was slower, but it was very stable.

About a quarter of an hour later, Zhang Yuwei saw a black and white pill appear in the two protective films, the two colors were constantly colliding, and soon, black had the upper hand, seeing this, Zhang Yuwei swiped his left hand, and the yang element protective film was directly integrated into the elixir, only to hear the sound of "boom", a black and white pillar of light shot out from the pill, Zhang Yuwei knew that this was Cheng Dan, he stood up, picked up the Yin and Yang Guiyi Dan, and handed it to Bai Luochen.

"After taking this pill, I will begin to stabilize the power of yin and yang in your body, and after your body is stable, I will detoxify you."

"Thank you, sir."

Bai Luochen looked at the yin and yang in her hand excitedly, she didn't hesitate, she took it down, suddenly, she felt full of bitterness, this pill was actually super bitter, but Bai Luochen didn't dare to spit it out, after all, the bitter taste of good medicine can be good for illness, she endured the bitterness and swallowed it in her stomach, after the pill entered the body, Zhang Yuwei walked behind Bai Luochen, he pressed his palm on Bai Luochen's vest, and the power of the yang element flowed out of Zhang Yuwei's palm and injected into Bai Luochen's body, Bai Luochen suddenly felt as if something was going to come out of his body, She spat out a mouthful of black blood, and then, black smoke emanated from her body.

With the increase in the injection of yang elemental power, sweat appeared on Bai Luochen's forehead, her expression was hideous, looking extremely painful, and the black gas was constantly coming out of her body, in addition to the black gas, Bai Luochen's body also emitted a rotten stench, as time went by, Bai Luochen's pain also increased point by point, she felt as if there were countless small insects tearing her skin, this pain made her can't help but make an "ah" sound.

"What's wrong, doesn't it hurt too much?"

Seeing Bai Luochen crying out in pain, Zhang Yuwei asked.

"Do you need me to slow down the rate at which Elemental Power is injected?"

"No need, sir, please sir push harder, the dust can be endured"

Hearing that Zhang Yuwei was caring about herself, Bai Luochen gasped, she closed her eyes, trying to endure the pain, although the transmission of the power of the yang element made her miserable, but compared to the previous life of not being able to raise her head, this pain was nothing.

Zhang Yuwei accelerated the rate of the power of the yang element in accordance with Bai Luochen's requirements, the black gas emitted by Bai Luochen's body, under the increase of the power of the yang element, became thicker and thicker, about ten minutes later, the black gas disappeared, just as Zhang Yuwei wanted to withdraw his hand, a cold came from his palm, and then looked at Bai Luochen, I don't know when, her body exuded bursts of cold air, and the surrounding ground formed frost under the influence of Bai Luochen, Zhang Yuwei immediately reacted, this is a seal.

He walked in front of Bai Luochen, said softly, "Offended", and directly lifted Bai Luochen's clothes, sure enough, a sealing formation was engraved on Bai Luochen's lower abdomen, because of the existence of the power of the yin element before, this sealing formation did not break out, so Zhang Yuwei did not find out, but because of the injection of the power of the yang element, the formation exploded, which also caused Bai Luochen's body to exude a chilling cold, although this cold made the ground of Danyang Hall condense into frost in an instant, but in Zhang Yuwei's opinion, This formation is still too simple, he who had communicated with the ancestor of the formation in the previous life, how could he not solve the formation, and it is the simplest formation, Zhang Yuwei ignited the Holy Dao Killing Tianyan on the index finger of his right hand, and clicked a few times on Bai Luochen's lower abdomen, and the Holy Dao Killing Tianyan entered Bai Luochen's body, and soon, the formation disappeared from Bai Luochen's lower abdomen.

At this time, Bai Luochen, because of the collision of several elemental powers in the body, his body was very weak, and the outbreak of the formation, so he fainted, Zhang Yuwei looked at Bai Luochen carefully with the eyes of the Holy Spirit, and found that the functions of her body had basically returned to normal.
