Bidding farewell to his teacher, Jiayi returned to his residence with worm tea.

After putting down the insect tea, Kaichi remembered the bonsai experiment he had mentioned in the morning. He certainly didn't want to replicate the experiment, but it proved that the most important thing for plants to grow is water, not soil. Based on this, soilless cultivation was developed.

Of course, soilless cultivation is not so simple, although water is the most important, but all kinds of mineral elements in it are also indispensable, without mineral nutrients, plants can not grow normally.

Of course, many plants seem to only need water to grow, such as pothos, fold a branch and put it in water to grow normally, Jiayi once raised onions, put the onion head into a bottle with the right opening size, to ensure that only the roots are in the water, and the onion head is above whomever face, you can feed.

However, because of the excessive amount of water, all the roots were immersed in the water, and eventually the roots rotted and died.

Because that onion eventually died, Jiayi's memory is extremely deep - that onion grew on his long table all winter, but died because of rotten roots when spring came.

Therefore, Jiayi knows that soilless cultivation is not so simple, the configuration of nutrient solution is very important, and the roots of the plant cannot be completely immersed in water, and a part of it needs to be left out to keep the roots of the plant breathing.

Jiayi now, is to use soilless cultivation to cultivate elf rice seedlings, rice is water-loving, seedlings can be completely soaked in water to grow, only grow to a certain extent when the grain is about to fill the field need to be released water, so the use of soilless cultivation to cultivate rice seedlings is the most suitable.

However, the most important thing now is to prepare the appropriate nutrient solution first, if the nutrient solution ratio is not suitable, the seedlings will be "burned" before they grow.

Jia Yi once asked Li Weier to apply to Professor Gwen to see the laboratory as their activity room, I don't know if I have applied now, I forgot to ask today, Jia Yi decided, I will ask tomorrow, if the laboratory has been applied, I will go to the laboratory tomorrow to start preparing nutrient solution.

The next day was not a day off, and Jia Yi found Li Weier before class, and as soon as they met, Jia Yi began to ask about the laboratory.

Li Weier said in surprise: "Are you in such a hurry? ”

After saying that, he also gave Jia Yi a roll of his eyes, feeling very dissatisfied that he came over so early to disturb himself for such a trivial matter.

Jiayi said apologetically: "I'm sorry, I came over when I thought of it, I didn't pay attention to the time, but you should be glad that I didn't come here last night, I thought of this last night." ”

Li Weier glared at Jia Yi angrily: "Then I should thank you?" I have already asked Professor Gwen, and the professor said that he can give us a laboratory as a support for our project, free of charge. In the laboratory just below the bell tower, we can even use the energy of the bell tower's elemental pool to a limited extent. ”

"So good? Professor Gwen is so nice to you. Kaichi looked surprised, feeling a little unbelievable.

The Academy's bell tower was designed with elemental pools to power the mechanical clock, so that the clock did not need to be wound all the time. However, if it is only to power the clock, there is no need for such an exaggeration as an elemental pool, and the energy in the elemental pool is more used to provide the laboratory under the bell tower, or to stimulate the powerful spells on the bell tower.

With the Elemental Pool as a backing, you don't have to worry about the lack of mana supply when conducting spell experiments, and you can conduct more demanding experiments, but if you need to have fine control over the mana, it is not suitable to use the Elemental Pool.

Li Wei'er struck him and said, "Don't be too happy, the professor only opened a small channel for us, and the output of magic is limited, so it is not possible to support some expensive experiments." ”

"It's good to have, I don't want too high a demand, you can take me over after class to see, I already have an idea, I can start experimenting with the cultivation of elf rice seeds. Jia Yi said to Li Weier.

Li Weier was surprised and said, "You have a plan so quickly, our seeds are not much, if they are wasted, there will be no second chance." ”

Jia Yi said: "Of course I won't directly experiment with elf rice seeds, we can experiment with wheat first, and then start experimenting with elf rice seeds after there are certain results." ”

After the two made an appointment, they each went back to class, and when it was noon, Jia got out of class and hurried towards the clock tower.

The clock tower is now a landmark of the college, and many students love to run here, especially those who are new to the college, and they must go down to the clock tower of the college when they arrive at the college.

The clock tower is the tallest building in the town, and when you arrive at the college, you will definitely see the clock tower if you look towards the center of the college, and it is difficult for anyone not to be attracted by the clock tower and visit it. Not to mention that the clock tower is rare in the entire continent, and this bell tower of the academy is the first bell tower in the entire continent.

After arriving at the Clock Tower, Li Weier was already waiting for him there, and after picking up Jia Yi, she took him to a laboratory under the Clock Tower.

This laboratory is not in the bell tower, the area of the bell tower is not large, so there are not many laboratories inside the bell tower, but the utensils and environment are the best, so it is very tight, Li Weier applied too late, there is no longer it, and it is impossible to occupy it for a long time.

So in retreat, Gwen arranged for them a laboratory near the clock tower, and gave them access to the elemental pool.

The basic utensils in the laboratory are readily available, especially there is a large glass window, the indoor light is very good, of course, there are magic lights in the laboratory, if you need a dark environment, just close the curtains.

Jia Yi looked at it a little, and said to Li Weier with satisfaction: "Senior sister, this laboratory is good, in the future, our studio, except for the part in the greenhouse, will all be concentrated here, it will be more formal, we need a desk by the window, as our desk, to deal with text work." ”

"Can you speak well, but also handle the text work, and write the experiment record is the experiment record. Li Weier looked at Jia Yi strangely, unable to understand what kind of rhetoric this was.

Jia Yi hurriedly said: "Okay, okay, the laboratory you applied for, you are the biggest, in the evening, we will come here and conduct the first experiment." ”

"In such a hurry?"

"Of course, there are only two months left in the semester, at least we need to let the elf rice seeds germinate. And we still have a lot of work to do with our plant taxonomy plan, and there are still some plants in the greenhouse that are not recorded, let alone the surrounding hills that the professor said. ”

Speaking of this, Jia paused for a moment, and looked at Li Weier with a sneer: "Senior sister~~"

The voice is long and clear, and tactful.

Li Weier swayed and said disgustedly: "What do you ask of me?"

"It's not a private matter, I just thought, senior sister, can you invite some helpers for us to come over and help us do the things of plant classification, this matter only needs to be careful, and it doesn't require much advanced magic attainment, and the requirements are not high. Jia Yi looked at Li Weier and said expectantly.

Li Wei'er stared at Jia Yi, and saw that Jia Yi felt a little embarrassed, so she said, "Since you don't have high requirements, why don't you go find someone to come over and help?"

"That, how can my appeal be as strong as that of Senior Sister, of course Senior Sister, it is better for you to be out of the horse. "Once Jia Yi asks for someone's head, he is a senior sister and a senior sister, and he has never been so attentive.

Although he said that the requirements are not high, a certain level of professionalism is still needed, such a person is at least a formal mage, but Jiayi's side lacks enough attraction, and he can't even get a decent reward.

He can only ask Li Weier's head, after all, the popularity of beauties is higher.

Li Weier originally wanted to ignore him, but she also spent a lot of time sorting plants, and now she is reluctant to let this matter end like this, and said: "I can find two people to come over to help, but I can't let people work in vain." ”

Jia Yi scratched his head, a little anxious about what he should take as a reward, and said with some hesitation: "It's definitely not okay to take money, they don't necessarily like it, and I'm not that rich, although Professor Gwen said that he can have some support, but it is estimated that there will be nothing good." Otherwise, the classification plan could be signed by them, and if the elven rice is grown, their names can also be included among the participants, but if it generates any benefits, it has nothing to do with them. ”

"Okay. Li Weier hesitated, "I'll try it and see if anyone is willing." ”

"There will definitely be, at least one. "What Jia Yi said was categorical, as if he had already decided who would come.
