After class in the afternoon, Jiayi and his group came to the laboratory to gather. Li Weier brought five people over, and the leader was Xiusli.

When I met the dragon carp last time, Jiayi found that the two of them were ambiguous. Now, as expected, when they saw Li Weier summoning, the other party ran over happily, just like a dog with flesh bones.

Jiayi glanced at Xiusli with contempt. With this look of a terrifying look, will she still have a family status in the future? If Jiayi had been, she would have come to help a long time ago, and was still waiting for Li Weier to summon her. She was really unconscious at all.

They didn't know that the other four people were actually brought by Xiusli. These four people were friends of Xiusli, and they had nothing to do recently. Xiusli was so pestered and pulled over to help.

If it weren't for Seusli, it would be hard to say whether anyone else came to help. Jiayi actually had some reputation, but it was not obtained in the academy. The rest of the people still had some doubts about Jiayi's ability, and it seems that plant classification is not a good project.

After working hard to sort it out, people only need to use it. They can get nothing but a little reputation. Of course, reputation is not useless. Most of the mages in this world are stuck at the level of a gray-robed mage, and having a little reputation is one head higher than others.

So the four people who were pulled over were not too reluctant, just felt a little embarrassed, because Jia Yi was younger than them and was a freshman in the first grade. No matter which world he was in, someone would value qualifications, but the mage had to be a little weaker before.

As for the matter of the elves rice seeds, the other people who came here except Xiusli did not know that if it was spread, there might be more people coming, but it might also attract people's jealousy. In order to keep it a secret, Li Wei'er did not promote it when she recruited people.

Kaichi and Seusli said hello and taught them how to record. Those places have been recorded and those things need to be recorded continuously.

After teaching them all, Jiayi came to the laboratory bench on the side and prepared to start preparing the nutrient solution.

Plant nutrient solution is actually not difficult, it is not easy to say, it is easy to germinate the seeds, and it is not even very difficult to grow up, but it is not easy to grow fast and healthy.

The most important element of plant growth is nitrogen, and this world should be no exception. Jiayi uses saltpeter and limestone, and a rock between quartzite and granite to grind it into powder, plus phosphite powder, and then dissolve it into water and mix it into solution, which becomes the first nutrient solution.

Saltpeter is easy to soluble in water and can provide a large amount of nitrogen and potassium. In Jiayi's previous life, he had compound fertilizers of potassium nitrate, but this thing is unstable. After the plate is solidified, it is easy to explode with a hammer and can also make gunpowder. It was later eliminated. The remaining stones are insoluble in water, but after being ground into powder and soaked in water, some of them will dissolve, providing plants with some trace elements.

With Jiayi's shallow farming experience and the biological knowledge he had learned, he can only think of this for the time being to prepare the nutrient solution for plants. Moreover, because of the lack of corresponding materials, he could only use this primitive method to prepare the nutrient solution. The ingredients of the nutrient solution obtained are not accurate, and he can only roughly estimate it.

Because of the composition of the stone, even the ingredients of the nutrient solution he prepared every time were different. Fortunately, plants, like humans, have certain self-regulation abilities and some differences in the ingredients, but as long as there are not too many differences, the problem will not be too big.

And there are magic assistance, which is Jiayi's confidence in exploring nutrient solution from scratch. With magic assistance, although it cannot guarantee success, the fault tolerance ability of the experiment is greatly enhanced.

Jiayi grinds the stones finely on one side. The finer the stones are, the more nutrients they dissolve. With the help of spells, each stone is ground into finely crumbs of soft dust like flour.

The few people brought by Seusley had not left yet. They were familiar with the props while seeing Jiayi grinding stones. One of them asked curiously: "Jiayi, what are you doing for grinding these stones? What is the purpose?"

Jiayi grinds the stone hard. Even with spell assistance, grinding the stone is not easy. He said without raising his head: "This is used to configure nutrient solution for essence..."

"Whoever cultivates plant seeds, he said that water is the most important thing, and soil is not important, so he should do some cultivation without any plans to cultivate plant seedlings." Before Jiayi finished speaking, he was interrupted by Li Weier and did not let him tell the story of the Elf Rice.

Regarding the fact that they are cultivating elves rice seeds, Li Weier and the others still hope to hide this matter first. Although no one dares to cause trouble in the academy, they can always avoid some trouble. Moreover, I don’t know whether this matter can be successful. Before the conclusion, Li Weier doesn’t want to promote it, so as not to make people feel that they are overestimating their abilities.

If it is really successful, it cannot be promoted. The benefits are too great, and someone may take risks. In short, it is better to keep it confidential before the results are achieved. Although many people know about Jiayi’s elf Dao Zhong, most of them are teachers, and few people know about this matter.

When Jia saw Li Weier interrupting her, she also understood that she didn't want her to spread the matter. Although he felt that it was a bit of a big deal, he didn't mind the other party's kindness.

Following Li Wei'er's words, he continued: "The most important water in the process of plant growth, and then minerals. Of course, sunlight is also indispensable. These do not necessarily require soil to provide it. Pastor Hymond's willow potted experiment has proved that soil is not as important as imagined. Great Druidsnebi further discovered photosynthesis, proving that sunlight is an indispensable condition for plant growth, and further established the mineral business theory, so these have formed the basis for no-picture cultivation."

Everyone was dizzy when Jiayi said this. These are knowledge in the field of plants, and the founders were not masters. Even Li Weier, who was meticulous in botany, had little knowledge of these, let alone the rest of them.

After all, botany is not a specialized planting. Jiayi's theoretical foundation just now, and the final soilless cultivation is actually in the category of agriculture. Among the mages, their knowledge of agriculture is undoubtedly relatively weak. Such talents are generally in various kingdoms, and almost none of them are mages. Because of their knowledge, they may have experience in planting crops, but their theory is much weaker than Jiayi.

Xiusli was very impressed by the way, and his confidence in Jiayi increased a lot: "Jiayi, how do you know so much? This knowledge is a little too rare."

"I like reading books and have a good memory. I remember it after reading it."

Jiayi couldn't tell them that these were what he had learned in his previous life. His educational experience in his previous life laid a solid foundation for him. Moreover, those textbooks were compiled and many years of experience in systematic teaching. The knowledge taught was more systematic. He didn't think about the other world. Although there was a college, basic education was more traditional like a private school or a tutor, and it was actually not very systematic.

Just this point, Jiayi left the rest of the people apart, not to mention that his scientific theoretical level in his previous life was much higher than that here. He also received the influence of the information explosion era, and his knowledge was incomparable to those of people here.

However, Jiayi knew that Heymond and the Great Druids Nayby had really found it by reading books. After comparing common sense in the two worlds, he found that many places of Wulihe chemistry knowledge were similar. He consciously began to compare the knowledge base in memory to find corresponding theoretical discoveries in this world.

In this way, even when copying a paper by yourself, you won’t accidentally crash. Moreover, through comparison, the learning and absorption speed has also been accelerated a lot, because this is not re-learning, it is just verification and adjustment.

There have been many theoretical discoveries in this world, some of which are equivalent to the level of the last world around the 19th century, but there are not many practical applications of theory. Perhaps because of the wizard's food and clothing, and the mastery of powerful power, the living standards of ordinary people in this world are still around the Middle Ages in Europe.

This actually gave Jiayi a lot of convenience. At least some basic prerequisites for theoretical research have been met, and "invention and creation" have become easier, making it more at ease.
