As soon as he arrived at the study, Yang Qizhen took out a book with the word "Dan Fang" on it. Ning Ping had a very strange feeling in his heart. Apart from other things, under the preconceived concept, since they would swallow him up sooner or later, why bother to teach him these things? Wouldn't it be better to just fool him later? Is he really planning to cultivate himself? Or is there another purpose? "Yes, Master." Ning Ping took the book and flipped through it. There were not many Dan recipes in it, only a few. There were four kinds of Dagu Dan, Buqi Dan, Zengyuan Dan, and Peiyuan Dan. In addition to Peiyuan Dan, Ning Ping himself had also secretly seen Yang Qizhen refine the others. After reading the Dan recipe, Ning Ping also knew why he had never seen Peiyuan Dan refine. The main effect of Peiyuan Dan is to strengthen the body and strengthen the body. This is also one of the few refined elixirs that ordinary people can take, and one of the main ingredients is the thousand-year-old spiritual ginseng. A hundred-year-old ginseng is rare, not to mention a thousand-year-old one. If you can barely reach the age of medicine, you have to be at least 500 years old. Because it is so rare, he has never been seen refining it. Or maybe it is because people of their level have already looked down on such medicinal effects. And the Qi-boosting Pill is actually an upgraded version of the Rejuvenating Powder, which has a more powerful healing effect. It didn't take long to finish reading a thin book. After two days of observation, Ning Ping found that even if there is a pill formula, it is actually quite difficult to refine it if you don't know the details. The most critical refining method of alchemy is often based on verbal teaching, such as the refining temperature, time, and techniques of each spiritual medicine, which all need to be taught and experienced.
But even so, this pill formula is indeed very precious. Even if you want to try it, if you don't have the pill formula and those clear quantities, you can't start. After seeing Ning Ping write down the pill formula, Yang Qizhen sent Ning Ping away without hesitation. This is equivalent to a day of rest, and Ning Ping is happy to do so. It seems that there is no need to think about the impact of Yang Qizhen's soul confusion yesterday. Back to the dormitory, Ning Ping greeted each other again when he arrived at the workshop. He even went to the warehouse to chat with Zong Yao for a while, but was impatiently kicked out by him. When he came to the room, Ning Ping actually wanted to take the Zeng Yuan Dan in the storage bag. He had never taken a pill before, and he was afraid that it would cause some noise, or his cultivation would improve suddenly. It would be strange if others didn't see it. The most important thing was that he was afraid that Yang Qi would attack him in advance after his cultivation was high, so he had been enduring it. Fortunately, there were also a bunch of Yiqi powder for his own practice. This kind of steady improvement in cultivation was exactly what he needed at the moment. He would take the Zeng Yuan Dan when he had the chance. Unexpectedly, the time for taking the real pill for the first time was coming to him soon. After the practice, Ning Ping came to the pill room in advance at dawn. Today was the time to refine the Bigu Pill. Ning Ping was also very excited to be able to personally observe the birth of the pill. This was much more enjoyable than peeking from the side. So he cleaned up the inside and outside early. Yang Qizhen felt refreshed as soon as he came in, and even nodded to Ning Ping with satisfaction. "Today we are refining the Bigu Pill, you have to watch carefully." After saying that, he did not waste time and directly led out the earth fire and began to warm the furnace. Then all the liquid medicines refined in the previous two days were taken out. "By the way, the spiritual rice liquid medicine you refined the day before yesterday was still good. Although it was not satisfactory, it was your first time to refine medicine and it was precious." Looking at the liquid medicine refined by Ning Ping in front of him, Yang Qizhen could not help but praise it, and then his face became serious and continued. "But don't be proud, this is still a long way to go! Refining the pill is like going deep into the sea, and you are just getting your soles wet now." "Well, follow the master's teachings." Ning Ping actually felt like a real master and apprentice at this moment. Everything was ready to start refining the pill, and Yang Qizhen rolled all the liquid medicine into the pill furnace at once. Ning Ping also observed carefully, and saw that with the continuous churning, all the medicine liquids were mixed together, and as the temperature rose, the impurities in the medicine liquid were further refined. He thought that most of the remaining impurities were probably from the medicine liquid he refined, and his face flushed slightly when he thought of this. As if he noticed Ning Ping's expression, Yang Qizhen on the side suddenly opened his eyes, a slight smile appeared on the corner of his mouth, and then his hands began to be busy again. Ning Ping certainly noticed Yang Qizhen's observation of him, and he became more alert in his heart, and he needed to be more careful in front of him in the future.
After a while, the medicine liquid was fully integrated, and the original beige color became deeper under the high temperature. "Divided~" At a certain time point, with Yang Qizhen's light shout, his fingers also fluctuated rapidly. At this time, the mixed medicine liquid in the furnace was quickly divided into hundreds of drops of water. With Yang Qizhen's control, these hundreds of drops of medicine liquid went up and down in the furnace, which was very beautiful. Ning Ping understood instantly that this was to ensure that all the liquid medicines were heated evenly. Slowly, under high temperature, the liquid medicines were further compressed. At this time, Ning Ping sensitively noticed that some of the liquid medicines seemed to have a slight difference in color. After thinking about it, it was not surprising that this was caused by uneven heating under control. If this idea was spoken out, Yang Qizheng would probably curse him as a monster. This was something that Yang Qizheng had slowly realized after almost a year of alchemy, and there was no way around it. This required great control ability and skills. Even now, Yang Qizheng cannot guarantee that all the pills can be completely consistent, which is the limit he can achieve. As time goes by, the original lychee-sized liquid medicine has condensed into the size of a thumb, and a hard core has formed faintly in the center of the liquid medicine, which is the performance of the pill starting to solidify. Seeing that all the pills are about to take shape and solidify, Yang Qizheng also turned off the ground fire. Under the residual heat in the furnace, all the pills solidified. The color is very different from before, it has become brown, and a familiar sweet smell comes from the top of the furnace. Suddenly, a pill exploded in the furnace, and then like a horn, a series of explosions continued to sound in the furnace, and the exploded powder turned into black ash, and fell to the bottom of the furnace under the suppression of Yang Qizheng's Yuanli. It was not until a long time later that the furnace finally quieted down. At this time, Yang Qizheng waved his hand to open the furnace cover, and dozens of pills were guided out and fell on the plate, making a mess.
