The higher the level of the prescription, the more powerful the interaction between the medicinal materials, if the cultivation is not enough, forcibly refining, the light medicinal materials will be destroyed, and the heavy ones will hurt their own body, it is the monk who invented the Dan furnace to help the alchemist share part of the pressure.

Pei Yuan Dan is a first-class inferior prescription, theoretically it can be refined if the qi is successfully induced, but in practice, almost no one realizes it, because any kind of pill requires extremely high proficiency, which means that the monk needs to spend a huge amount of divine consciousness to practice, and the cultivator's divine consciousness with low cultivation is already limited, and it is tantamount to a drop in the bucket to practice alchemy, so the monk with low cultivation will hardly try alchemy.

And Liancheng was able to successfully refine Pei Yuan Dan during the Qi Induction Period, both the Cheng Dan rate and the quality of the pill were very impressive, it was really because in his previous life, Liancheng was already a third-level first-turn alchemist, and this kind of first-level inferior prescription was as simple as asking a college student to do elementary school math problems.

But what is bothering Liancheng now is his divine sense, a qualified alchemist needs to monitor the changes in medicinal properties all the time, and the slightest mistake will fall short, and the more complex and subtle the changes in medicinal properties, the more divine consciousness will be consumed.

With Liancheng's current divine sense, it is a little difficult to turn a superb Peiyuan Dan into the second turn, and it is estimated that the divine consciousness will be exhausted before the third turn is over.

It has been a day since the public bidding of Crescent Lake, and Liancheng has also stayed in his room for a day, looking at the black powder in the crucible, Liancheng sighed helplessly, without the help of the Dan furnace, with his current cultivation, it is still a little reluctant to refine the best Peiyuan Dan for the second turn.

The first refinement failed, and the second attempt could only wait for the divine consciousness to recover.

There are only two ways to restore divine consciousness, one is through pills, and the other is through natural recovery.

At the thought of recovering his divine consciousness through the elixir, Liancheng was eager to raise his cultivation to the fifth level of Qi training, because the cultivation of the fifth layer of Qi cultivation could refine the Awakening Divine Pill.

The best way to recover naturally is through deep sleep, which is much easier for monks than for mortals.

......

As soon as he woke up, Liancheng took out a top-grade Pei Yuan Dan and tried to refine it again.

The higher the level of the prescription, the higher the requirements for fire, like Pei Yuan Dan, a first-class inferior prescription, can be used with fire.

The minimum temperature required to refine Pei Yuan Dan is 900 degrees Celsius, and the heating temperature of the alcohol lamp reaches more than 400-1000 degrees Celsius.

Liancheng infiltrated the divine consciousness into every corner of Pei Yuan Dan, with the increase in temperature, the surface of Pei Yuan Dan body seems to have no change, but in fact, it has long since expanded, if you look at it with a microscope now, you will find that the distance between the various molecules in the Dan body is gradually expanding, at this moment the entire Dan body is in a state of wanting to disperse, if there is an outsider on the Dan body at this moment, it will be strange to find that a good solid object, has suddenly become powder.

Liancheng felt that he had entered a scorching sea of energy, and the surrounding energy seemed to be mild, but it was actually full of danger, turning into a monstrous wave to drown him at any time, and at that time, that is, when Pei Yuan Dandan was destroyed, and all he could do was to withdraw his divine consciousness as soon as possible, so as not to hurt himself.

In the Dan body, there are some molecules of different shapes between the mild energy molecules, and these molecules are magazines! What Liancheng has to do is to use high-temperature expansion to "squeeze" these magazines out, and in the process of "squeezing", these impurity molecules are prevented from colliding with the effective molecules.

With Liancheng's current divine sense, he can't see the molecule so small, he can only use his divine sense to feel, and by discerning the energy attributes, what is different from most is magazines.

Liancheng used his divine sense to control those magazines, moving to the outer layer closest to the Dan body, this experience is a bit similar to a trap game of hell-level difficulty, and he fell into the trap if he was a little careless, but it is much more difficult to refine Pei Yuan Dan than the hell-level difficulty, because those traps are at least very clear, as long as you follow the expected plan, you can pass the level, while the "trap" in Dan's body is much more vague, and you can only feel it with your divine sense.

The divine consciousness is exhausted little by little, and the impurities in the Dan body are gradually discharged, until the entire Dan body is investigated, and there is no impurity at all, then the first refining, that is, "one turn", is half successful.

The various components in the Dan body once again interacted with each other, and while the efficacy of the medicine was improved, some impurities were formed.

This process is a little easier than refining as long as the small reactions are controlled to proceed normally.

Until the reaction stopped, Liancheng removed the alcohol lamp and waited for the Dan body to cool down, while using his divine sense to maintain the Dan body from falling apart.

This refining is a day's work, although there is still a remnant of divine consciousness, but Liancheng is not ready to perform the second turn immediately, because the lesson of the previous car a day ago is there, for the sake of safety, it is better to wait until it has returned to a complete state before performing the second turn.

......

Qu Xiaoxuan waited all night and didn't wait for Liancheng's apology, the more she thought about it, the more angry she became, she regarded Liancheng as a friend, but Liancheng treated her as an outsider, she Miss Qu had never been so angry, and her cool temperament attacked, and she didn't even say hello the next morning, so she went back to Humen.

Liancheng came out of retreat for two days before he heard the old man Huangfu say that Qu Xiaoxuan had returned to Humen.

He didn't say anything, didn't he say anything? This eldest lady of Qu Xiaoxuan has too much temper, right?!

After resting for a while and making sure that he was in a complete state, Liancheng closed the door again.

After a turn, the medicinal effect of Pei Yuan Dan was much stronger, but it was accompanied by more abundant energy after digging again, and the more difficult it was to refine, the more difficult it was to refine, and in the process of gradually "carrying" the magazine, there were several times when the magazine almost touched the active ingredients of the pill, resulting in the destruction of the pill.

I don't know how long it took, maybe it was a high degree of mental concentration, Liancheng only felt that a short time had passed, and when the last bit of magazine was discharged, Liancheng was suddenly shocked.

In the end, the second best Pei Yuan Dan was successfully refined.

......

Intensive Care Area of the First People's Hospital of Jingzhou City.

Huang Fuqi and the two were hugged by a large group of people and walked to the intensive care unit where Chen Hai was.

"Qizi, is this Doctor Lian really sure that he can cure Xiaohai?" Chen Yanyan had asked this sentence no less than ten times, and when he asked it again, his voice was still a little trembling.

An elderly woman with a good temperament next to Chen Yanyan also looked at Huang Fuqi with blank eyes, she was Chen Hai's mother Wang Fuzhen.

Three days ago, Chen Yanyan and his wife received a call from Huang Fuqi, saying that they were ninety percent sure that Chen Hai would be cured, and at that time they thought they were dreaming, and they were circling day and night, didn't they hope that their son could wake up?

Subconsciously, Chen Yanyan and his wife understood that with current science and technology, it was impossible to cure a vegetative person.

But Huang Fuqi swears by what he said, and with Chen Yanyan's understanding of him, although Huang Fuqi has a strange personality, he is still very reliable, so Chen Yanyan and his wife, who were already desperate, suddenly had hope. But this hope is a little untrue, because they didn't even tell Chen Hai's son Xiao Piqiu.

"Old Chen, don't worry, I will definitely cure Chen Hai! Even if there is a 10% chance of failure this time, but next time, next time, there will always be a success!"

Huang Fuqi and Liancheng talked about Chen Yanyan's life, for such a person who dedicates his life to the country without hesitation, in today's impetuous society, there are almost no such people, Liancheng prides himself on being a person with a national concept, but compared with Chen Yanyan, it is a heaven and an underground, so Liancheng respects him in his heart, such a person who dedicates his life to the country should enjoy his old age in peace. Maybe the country is too big to take care of all people like Chen Yanyan, since Chen Yanyan was accidentally missed and bumped into by him, Liancheng doesn't mind helping him, and it is also beneficial to himself.

"Good, good, good..." was assured by Liancheng, perhaps because of excitement, Chen Yanyan nodded a little out of shape.

When I arrived at the door of the intensive care unit where Chen Hai was, there was a doctor in the room examining Chen Hai.

Lian Cheng looked towards the hospital bed, this is Chen Hai, right? Chen Hai has upright facial features, very thick eyebrows, and looks majestic and upright. The lips were surrounded by a shaved black blue beard, apparently being taken care of from time to time.

The middle-aged doctor who was checking Chen Hai's physical condition was the director of the neurology department, and as his son's attending doctor, Chen Yanyan still respected this doctor who was dozens of years younger than him.

"Director Wang, how is Xiaohai's situation?" Chen Haihai asked, looking worried.

Director Wang first glanced at Liancheng and Huang Fuqi, frowned inadvertently, and said lightly: "Elder Chen, Elder Wang, judging from the various data of Chen Hai's body, you took care of it very well before, but..."

"But what?!" Wang Fuzhen looked anxious.

"But what I said about you before, you seem to have forgotten, didn't I say that Chen Hai's current situation can't be disturbed by too many people, let alone strangers, even if it is a close person who helps Chen Hai wake up, he should keep speaking softly!" Director Wang looked a little angry.

"Director Wang, you misunderstood. You're a professional, and we've always done what you say. I asked these two to take a look at Xiao Hai's condition, maybe they can cure Xiao Hai!"

Director Wang was stunned at first, and then examined the two of them separately, Liancheng Qi was thin and sick, and Huangfu Qi was indeed a little unusual, but Director Wang's eyes flashed with disdain: "Are they doctors?"

Chen Yanyan and his wife glanced at Liancheng and the others, they didn't expect Director Wang to ask this question, and they didn't know how to answer for a while.

If you can cure diseases, aren't you doctors?

The movements of Chen Yanyan and his wife, Director Wang saw it in his eyes, and the corners of his mouth were raised lightly, containing a trace of contempt that was not easy to detect.

"If you are not a registered doctor, you are not qualified to practice medicine, and even if you are a doctor, you cannot treat my patients without my permission. If it weren't for me, Wang Yuping, who happened to bump into me today, I'm afraid you would have succeeded in deceiving, right?!" Director Wang sneered.
