Su Han quickly understood Zhou Deming's intentions, and he could find some shortcomings and deficiencies after alchemy every day, which made him deeply realize that practice was far more important than theory. After a day of thinking, sometimes without Zhou Deming's explanation, Su Han can solve the problem.

Such a state made Su Han's alchemy skills improve rapidly.

One day a month later, after Su Han came out of the alchemy room, he found Zhou Deming, took out a bottle and said, "Uncle Shi, what do you think of the quality of this elixir?"

"Alcheming?"

Su Han nodded, "But I think there are some differences with the pure Pure Heart Pill." ”

Zhou Deming took out a pill and smelled it, ate another one, tasted it carefully, and said after a while: "There is a deviation, but the effect of the medicine is not much different, and even some aspects are better than the orthodox Qingxin pill." Since each monk's control method is different, there will always be differences in the elixirs they refine, and it is not your problem. ”

"It seems that your basic technique has matured, and from tomorrow, you will start refining Zhu Lingdan. Zhou Deming said.

Zhu Lingdan was chosen by Su Han after consulting Zhou Deming, this elixir is particularly useful for the rush of monks in the middle of the Qi refining period, and it is only a pill under the ninth grade, which is one level higher than the Qingxin Pill, Su Han wants to refine it now, and then impact the fifth layer of Qi refining, Zhu Lingdan is the most suitable. Farewell to Zhou Deming, Su Han returned to the firewood room.

He checked the contents of the bag, and his brow furrowed.

At the beginning, a sect trial made Su Han change from a poor bastard to a little rich man with 20,000 spirit stones. But later, he broke through from the third layer of qi refining to the fourth layer of qi refining, and the expenditure of three months of cultivation cost him 2,500 spirit stones. In the battle of Pingzhen Mine, a total of 4,000 spirit stones were spent to buy talismans and indigo wood. Then he returned to Minggou Mountain so far, in the past four months, Su Han and Fen have consumed 6,000 spirit stones for cultivation alone, not counting Zhou Deming's teaching fees, the rental fees of the alchemy room, and the large amount of medicinal herbs consumed in practicing alchemy. After a calculation, in the seven months after the sect trial, he had already spent 15,000 spirit stones.

"I thought that 20,000 spirit stones would be enough for me for a long time......" Su Han rubbed his forehead, a little headache, but now it seems that he is afraid that the remaining spirit stones will not last for two months.

"Now that I have reached the peak of the fourth layer of qi refining, I have also reached the late stage of the fourth layer of qi refining, as long as I refine Zhu Lingdan within a month, I can start to break through the fifth layer of qi refining. ”

After some discussion with Zhou Deming, he extended the time he spent in the alchemy room to three hours a day, and for this reason he had to compress the time for cultivating the "Imperial Things" and reading the "Compendium of Materia Medica".

The adjustment of the cultivation plan was fruitful, and after half a month, Su Han was finally able to refine the Zhu Ling Pill with ninety percent medicinal effect, but the large consumption of medicinal materials also exacerbated the shrinkage of Su Han's wealth.

Looking at Su Han's latest bottle of Zhu Lingdan, Zhou Deming nodded, "Yes, looking at the last few times you have refined Zhu Lingdan, it has been stable at about ninety percent of the medicinal effect, which is good, the reason why it has not reached ten percent is that the quality of the Dan furnace and flame is insufficient, the second is that the quality of the medicinal materials is defective, and the third is your own lack of experience." After studying alchemy for four months, you can refine the elixir under the nine grades, which is very good. ”

Su Han asked, "Uncle Shi, what is the price of my refined Zhu Lingdan?"

"About 20 spirit stones. Zhou Deming said, "If it is ten percent, the price can be doubled." However, ninety percent of the pills don't have to worry about sales, and Zhu Lingdan has a great effect on the monks from the third layer of Qi refining to the seventh layer of Qi refining, so it is very easy to sell. ”

"It's only 20 spirit stones?" Su Han couldn't help but shake his head when he heard this, refining Zhu Lingdan once can get 4 to 6 Zhu Lingdan, the material cost is 30 spirit stones, and it takes another 3 hours of refining time, that is, he has to pay the rental fee of the alchemy room of 30 spirit stones in the Herbal Pavilion.

In this way, he worked hard for three hours, and he could only earn a maximum of 60 spirit stones, which was not enough for him to cultivate every day now.

"What, do you want to earn spirit stones from this?" Seeming to see what Su Han was thinking, Zhou Deming asked.

"It's not a big profit, forget it. Su Han shook his head, since he earned 20,000 spirit stones in the first sect trial, Su Han didn't think much of the dozens of spirit stones.

"At this stage, it is not easy for you to earn spirit stones, the efficiency of earth fire is too low, it is difficult to refine high-value pills, and it is only feasible to rely on alchemy to earn spirit stones when you condense the pill during the foundation building period. Zhou Deming said, "Of course, the premise is that you can refine a high-quality elixir. The better the pill, the more difficult it is to refine, and many monks can often refine more than eighty percent of the pill when refining the pill during the Qi refining period, but when it comes to the foundation building period, the quality of the pill that is refined and cultivated to the corresponding grade will drop to four or five percent. And another point, the factor of the Dan furnace is also very important, if you have a Dan furnace of more than eight grades, alchemy will save a lot of effort. ”

"What is the quality of the elixir refined by Uncle Shi?" Su Han asked curiously, this was also a question he had always been concerned about. Because in the past few months, Su Han didn't feel that Zhou Deming was half-baked in terms of alchemy.

Zhou Deming smiled bitterly, shook his head and said: "It can be regarded as entering the hall, it's not that I boast, many alchemists in the same realm of the inner door are not as good as me." ”

"Huh?" Su Han said curiously, "If Uncle Shi is so powerful, shouldn't he be in this Qingshui Yamen?"

Su Han had studied alchemy from Zhou Deming for four and a half months, and he knew what the situation was like in the Materia Medica. The main income of the Materia Medica Pavilion is to purchase medicinal herbs, resell them or refine them into pills and sell them. Like Su Han, who invests thousands of spirit stones to learn alchemy every month, he can't find one among the thousands of people on the two mountains of Minggou Huyue. Because the competition between the outer disciples was so fierce, everyone focused on improving the realm, so that not many people were willing to spend effort to learn alchemy.

"Hey, hey. Zhou Deming smiled faintly, but he couldn't hide a hint of gloom, "The cause and effect in the meantime is not enough for outsiders, so I will sue you again when I have the opportunity in the future." ”

At this time, Su Han suddenly took two steps back and bowed deeply to Zhou Deming, "Uncle Shi, for these four and a half months, thank you for your careful teaching." ”

Zhou Deming smiled and said: "I know, you won't stay here for too long, go, the outside world is what you should break through, on Minggou Mountain, a comfortable monastic life will only smooth out your edges and corners." ”

"Uncle Shi knows?" Su Han was surprised, and seemed strange that Zhou Deming actually knew about his plans.

"You have spent a lot of spirit stones during this time, and there is no source of spirit stones, it is not easy to cultivate in peace and stability for so long, I estimate that you will have to go out. ”

"Go, cultivator, you must enter the world to know the changes in heaven and earth. ”

Su Han bowed deeply to Zhou Deming again and withdrew from the Materia Medica Pavilion.

When he returned to the firewood room, from a distance, Su Han saw Zhang Zhong and Wang Yuan, waiting at the door of the firewood room.
