Ancient pharmacists pursued complex refining and fusion, and some medicines even had to be refined thousands of times, and this method of chemical changes in refining is called Alto's law, which was invented by a pharmacist named Alto 4,000 years ago.

It is said that this person seemed to be in some kind of epiphany at that time, so he unconsciously refined the potion repeatedly, and when he finished the epiphany, he found that the potion in his hand had completely changed and changed into another one. At first, he thought that his family had made some kind of joke with him, but then he watched the video and realized that the potion in his hand was not someone else's prank, it was really refined by himself, and after calculation, the number of times he refined it reached 1,250 times, and a new chapter in the field of pharmacists began.

This kind of refining can achieve more than 1,000 transformations is called Alto's law, and the use of Alto's law not only has high requirements for the quality of the refined medicinal materials, but also the refining technology. And this kind of medicine that has been quenched thousands of times is even more difficult to mix with other medicines, because the refining of thousands of times will make the medicinal properties very unstable, and then add something else, that is, the trend of Mars hitting the earth. The slightest miscalculation in the middle could lead to a big explosion.

In the first class of refining potions, when she was refining to the thirtieth time, there was an explosion, which scared Wang Yujin a lot, but fortunately she reacted very quickly and dodged in time, otherwise she would be in danger of disfigurement. Now she finally understands a little bit of the old man's intentions of the light brain, why she is in a hurry to learn to dodge, and dare to be used here.

That's why it's very difficult for ancient pharmacists.

Although her progress in mastering knowledge is very fast, but what pharmacists have to pay attention to is still a practical problem, if she can't even do the most basic refining, then she doesn't need to do this profession, so in the days to come, Ji Qiongzhen will put refining potions in the first place.

At the same time, all kinds of martial arts are also steadily learning, these are what she has lacked learning in the past, after all, she is a girl, and she didn't need to learn anything if she had a family to protect her, but now it is completely different, it can be said that the sky fell in an instant.

From time to time, there would be bursts of explosions in the room, and a spider in the plant cultivation room was sleeping dimly, and in its deep sleep, its shell was also changing, and a little red spot appeared on the originally snow-white body, if you don't look closely, it looks like it is splashed with blood to the dripping blood droplets.

"Bang!" Another huge explosion sound came from the real yàn room, Wang Yujin was very helpless to accept the Nth failure, she came out of the real yàn room in frustration, this time even her hair could not escape, all the gray face exploded, but looking at her own appearance, Wang Yujin couldn't laugh at all, but fortunately, the real yàn room on the warship was specially reinforced at the beginning, otherwise the entire warship might be destroyed by her explosion.

"Old man, did you teach me the wrong method? Where can there be so many failures?" Wang Yujin couldn't help but think.

"If you are stupid, don't say that I am wrong in teaching, first of all, you can calm your mind, I think your mentality is not good, how to do good things in a boring way? Light Brain said.

In fact, in the light brain's opinion, Wang Yujin is already a ** type, for some reason he has to teach quickly, so where is the course taught to her, which is the class of the newly enrolled students, and it is already the course of a junior pharmacist.

This is like the rhythm of letting primary school students take college classes, like ordinary freshmen who have just entered the pharmacist as long as they can refine the pharmacy is already qualified, and then slowly accumulate, to the middle grade stage to require repeated refining more than 30 times, and this also needs to be accumulated for a long time, like the previous students, which is not studied for three or five years before reaching the middle grade, but to be upgraded to the senior level, it must be refined more than 100 times, and the pharmacist freshman who can be refined more than 100 times is considered to have just entered the threshold of pharmacist, called a pharmacist apprentice, and the transition from apprentice to junior pharmacist is very simple, as long as you can innovate and mix a pharmacy yourself, whether it is simple or complex, as long as the innovation is successful, there is no medicine with the same formula on the market, you can directly advance, otherwise you can only use the quantity to accumulate the maturity, as long as you can achieve the mixture and purification of more than five kinds of liquids, including five kinds of liquids, you can advance to the pharmacist.

Generally, it takes thirty or forty years for a student to become a full-fledged junior pharmacist from entering school. And some people with bad talent can be said to spend a whole day chasing the path of pharmacist, and it is also common.

In the interstellar era, due to the changes in the form of human life itself, the internal organs can be simply cultivated, the emergence of a variety of medical warehouses seems to make the traditional doctors have no room to play, and the emergence of pharmacists can be said to be a kind of transformation, this kind of manual ratio to enhance the potion, the effect is extremely obvious, coupled with the various needs in the expedition, pharmacists not only have to understand pharmacology, but also make professional judgments on plants, many senior pharmacists themselves are a good master of plant communication, if they can communicate with plants, then they can undoubtedly get twice the result with half the effort in the expedition。 Pharmacists developed most rapidly in the early days of the universe, and there were many famous pharmacists in that era, but with the development of the universe, many plants were collected, just like the earth back then, and the useful species disappeared, which also made it more difficult for pharmacists to develop in the future, even if they were talented, they also had to have materials.

As a qualified pharmacist, not only must have good skills, but also master the pharmacist's various prescriptions, these ordinary prescriptions can be mastered in public classes when there is still zài in school, and some special formulas must be exchanged for contribution points, and now the kingdom school may not be available, of course, the recipes of these pharmacists stored in the zài light brain also belong to the light brain's private, and it depends on his preference whether he likes to give it or not.

As for Alto's law, it is also something that pharmacists above level 3 need to master, and it is too early for a new pharmacist who has just started to know.

Ji Qiongxin is not only learning drug refining now, but the light brain has already let her learn the preliminary fusion according to her situation.

Originally, Wang Yujin thought that she could be very successful in fusing two drugs at one time, even if she failed a few times, but she was wrong, the fusion of the three drugs was far more difficult than she imagined, this was her hundredth failure, this time she felt that what the light brain said might be right, she put too much pressure on herself, but I don't know why she has an indescribable feeling of irritability recently, as if she wants to vent.

"Old man, is there a challenge that is a little more difficult?"

"What kind of nerves do you have, what kind of challenge do you want?" said the light brain in a daze.

"Don't be so stingy, I actually know that every trial will consume a lot of your energy, but the ones you give are too pediatric, and it doesn't matter if it's more difficult for me, it's a big deal to re-cultivate, at least if you succeed, I can't be promoted." You also know that I was about to be promoted to the red level before I came here, and because I was suppressed, this energy will become a disaster in my body sooner or later. After all, she has already stood at that height, so she can see where her problem lies, if she doesn't enter the red-level door, then she won't feel that something is wrong in her body, this is where the five elements are so decisive, and it's no wonder that my father used to always boast that the family exercises were the most secure exercises in the whole universe.

Wang Yujin hesitated as soon as he said that he had his own calculations, he was actually more afraid of failure than Wang Yujin himself, after all, this was the only student he taught as a professor, could he not care? But there is also a problem that the energy on the ship is also constantly depleting, he has turned off most of the functions on the ship, even if Wang Yujin does not come, he will not be able to support it for long. Glancing at Wang Yujin, he decided to believe her once.
