On the blue stone brick next to the elixir is a dense array of runes carved by Han Chujiu. He carved one at a time, another at a time, turned his head, frowned again, and crossed out one of them. After fiddling with several runes, he went back to explore the elixir with divine sense, then frowned and recorded something on the paper. Han Chujiu's research has completely exceeded Mu Yan's knowledge of alchemy. After only a few eyes, she went back to continue refining her own pills. After more than ten hours, Mu Yan looked at the successful refining of a batch of pills and breathed a long breath. With Han Chu Jiu's Alchemy furnace and inheritance, she has made rapid progress in alchemy. However, it seems that there is still something missing, which makes it impossible to meet the requirements of the ninth master. Master nine is obviously a man who pursues perfection. First of all, the first point is the requirement for the purity of pills. On the market of Xiuzhen, the purity of common pills can reach 60%. A great alchemist can reach 70% or 75%. Now, without using Yunsheng Jiehai, the purity of Moyan pills can reach 80%. If such pills are taken out for testing, they can definitely scare a lot of people's chin. 85% purity of pills, almost can be said to have no erysipelas, not to be reversed. But in Han Chujiu's eyes, the 85% pure pills are just waste, and it's also a waste to eat. Han Chujiu's requirement is that, in addition to poison pills and pills that produce side effects, the purity of other pills is 85% passing, 90% unsatisfactory, and 95% qualified to be Han Chujiu's Apprentice. Muyan uses the magic weapon in the inheritance space to test the newly refined pills. 83 percent! Tut... Mu Yan frowned, even nine master's pass line did not reach. After refining Dan for a whole day, Mu Yan was a little tired, and even more confused. Instead of choosing to continue alchemy, she left the inheritance space and went to sleep. However, this sleep is not stable. Mu Yan is in a trance and hears a cry ringing in her ear. She stood in the void, looking at the direction of the cry ahead. However, the eyes seem to be covered with a layer of fog, can not see. Only vaguely see someone lying on the bed, surrounded by people uneasy fear of black gas. There were people kneeling around the bed, and the cry came from these kneeling people. Mu Yan in a dream, everything is chaotic, also can't see who is on the bed. Can look at him, listening to the cry, but inexplicably feel a cone of pain and panic spread throughout the body. Mu Yan tried his best to go to the direction of the bed, and wanted to see the appearance of the man. Slowly, close, close. The original vague cry, seems to be mixed with a few ambiguous syllables: "medicine... Antidote..." in front of the fog seems to be suddenly pulled away, the man's face instantly clear. However, without waiting for mu Yan to take a closer look, she seemed to be hit by something and suddenly woke up. Muyan sits on the bed, gasping, vaguely feeling that he has dreamt of something suffocating and sad, but he can't remember anything when he opens his eyes“ Mother Xiaobao rushed into her arms and looked at her anxiously, "mother, how sweaty is your forehead? What's the matter? " Mu Yan gently touched his small face: "mother had a nightmare, some fear."
