After saying goodbye to his teacher, Jiayi took Chongcha back to his residence.

After putting down the insect tea, Jiayi thought of the pot plant experiment he mentioned in the morning. Of course, he did not want to replicate this experiment, but this experiment proved that the most important thing in plant growth is water, not soil. Based on this, soilless cultivation has been developed.

Of course, soilless cultivation is not that simple. Although water is the most important, various mineral elements are also indispensable. Without mineral nutrients, plants cannot grow normally.

Of course, many plants seem to only need water to grow, such as green ivy, fold a branch and put it in water to grow normally. Jiayi once raised onions and put the onion heads into a bottle of appropriate opening size to ensure that only the roots are in the water, and the onion heads can be raised on whoever they are on.

However, because there was too much water later, all the roots were immersed in the water, which eventually led to the roots rotting and death.

Because the onion eventually died, Jiayi's memory was extremely deep--the onion grew on his own long table for the whole winter, but died of rotten roots when spring came.

So Jiayi knew that soilless cultivation was not that simple, and the configuration of nutrient solution was very critical, and the roots of the plant cannot be completely immersed in the water, so a part of it needs to be left to keep the plant roots breathing.

Jiayi now wants to use soilless cultivation to cultivate seedlings of elf rice. Rice is water-loving, and seedlings can be completely soaked in water to grow. Only when they grow to a certain extent, they need to be put into water and dry the fields. Therefore, it is most suitable to use soilless cultivation to cultivate rice seedlings.

However, the most important thing now is to prepare a suitable nutrient solution first. If the nutrient solution ratio is not appropriate, the seedlings will "burn" before they grow out.

Jiayi once asked Professor Gwen to apply to Professor Yishiwei to see the laboratory as their activity room, but I don’t know if I have applied for it now. I forgot to ask today. Jiayi decided to ask tomorrow. If the laboratory has been applied, I will go to the laboratory to start preparing nutrient solution tomorrow.

The next day was not a day off. Jiayi found Li Weier before class. As soon as he met, Jiayi started asking about the laboratory.

Li Wei'er said in surprise: "Are you so anxious? You came here so early and asked about this."

After saying that, he rolled his eyes on Jiayi, feeling very dissatisfied with him coming so early to disturb him but for such a small thing.

Jiayi said apologetically: "Sorry, I came here when I thought about it, and didn't pay attention to the time, but you should be glad that I didn't come here last night. I thought about this last night."

Li Weier glared at Jiayi with anger: "Then I should thank you more? I have asked Professor Gwen, and the professor said that we can give us a laboratory as support for our project, and there is no charge. In the laboratory below the clock tower, we can even use the energy of the element pool of the clock tower with limited energy."

"So good? Professor Gwen is so nice to you." Jiayi showed a look of surprise and felt a little unbelievable.

When the bell tower of the college was designed, an element pool was built to power the mechanical clock, so that there was no need to always wind the clock. However, if the clock was just powered, there was no need to be such an exaggerated element pool. The energy in the element pool was more used to provide the laboratories below the bell tower, or to stimulate the powerful spells on the bell tower.

With element pools as a backing, you don’t have to be afraid of insufficient magic supply when conducting spell experiments. You can conduct higher-demand experiments. However, if you need to finely control magic, it is not suitable to use element pools.

Li Wei'er hit him and said, "Don't be too happy too early. The professor only opened a small channel for us. The magic power output is limited. It's not enough to support some expensive experiments."

"It's good to have it. I don't want too high requirements. After class, you can take me over and take a look. I already have a way of thinking and can start experimenting with planting elf rice seeds." Jiayi said to Li Weier.

Li Weier said in surprise: "You have a plan so soon? We don't have many seeds. If we waste them, we will not have a second chance."

Jiayi said: "Of course I won't directly use the elves rice seeds for experiments. We can first use the wheat to experiment, and then start using the elves rice seeds for experiments after a certain result."

After the two made an appointment, they went back to class. At noon, Jiayi hurriedly ran towards the clock tower.

The bell tower is now a landmark building of the college. Many of the students like to run here, especially those who have just arrived in the college to visit. When they arrive, they must come to the bell tower of the college.

The clock tower is the tallest building in the college town. After arriving at the college, you will definitely see the clock tower as long as you look at the center of the college. It is difficult for anyone to not be attracted by the clock tower and go for a visit. Not to mention that the clock tower is rare in the entire continent. The clock tower of the college is the first clock tower in the entire continent.

After arriving at the bell tower, Li Wei'er was already waiting for him there. After receiving Jiayi, she took him to a laboratory under the bell tower.

This laboratory is not in the bell tower, and the area of ​​the bell tower is not large, so there are not many laboratories inside the bell tower, but the equipment and environment are the best, so it is very intimate. Li Wei'er applied too late and has long been gone, so it is even more impossible to occupy it for a long time.

So, after a second try, Gwen arranged a laboratory near the bell tower for them and gave them permission to use the element pool.

There are all basic tools in the laboratory, especially with a large glass window, which has very good light in the room. Of course, there are magic lamps in the laboratory. If you need a dark environment, just pull up the curtains.

Jiayi took a look and said to Li Weier with satisfaction: "Senior sister, this laboratory is good. In the future, our studio will be concentrated here except in the greenhouse, which will look more formal. We need a table by the window to serve as our desk to handle text work."

"Can you speak well? You also handle writing work. Writing experimental records is just experimental records." Li Wei'er looked at Jiayi strangely, unable to understand what kind of rhetoric this was.

Jia hurriedly begged: "Okay, the laboratory you applied for is the biggest. In the evening, we will come here for the first experiment."

"So urgent?"

"Of course, there are only more than two months left in the semester. At least we have to let the elves rice seeds sprout. Moreover, our plant classification plan still has a lot of work, and there are still some plants in the greenhouse that have not been recorded, let alone the surrounding hills as the professor said."

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

The sound is long and clear, and it is endless.

Li Wei'er beat her up and said disgustedly: "What else do you ask me for?"

"It's not a private matter anymore. I just thought, senior sister, can you ask us some helpers to help us sort plants? This matter only requires carefulness, not very profound magical attainments, and the requirements are not high." Jiayi looked at Li Weier and said with anticipation.

Li Wei'er stared at Jia, and felt a little embarrassed when she saw Jia Yi, and then said, "Since the requirements are not high, why don't you find someone to come and help?"

"Well, my appeal is not as strong as that of senior sister, you are the senior sister. Of course, it is better for senior sister." Once Jiayi asked someone for help, senior sisters kept going and never was so attentive.

Although he said that his requirements were not high, he still needed certain professional qualities. Such a person was at least a formal wizard, but Jiayi lacked enough attractiveness and could not even get a decent reward.

He could only ask Li Weier for the sake of his life, after all, the popularity of the beauty is higher.

Li Wei'er originally wanted to ignore him, but she also spent a lot of time on plant classification. Now she is reluctant to let the matter end like this, saying, "I can ask two people to help, but I can't let others work in vain."

Jiayi scratched his head, anxious about what he should pay for, and said hesitantly: "It is definitely not possible to get money. They may not be worthy of it, and I am not that rich. Although Professor Gwen can have some support, there is probably no good thing. Otherwise, this classification plan can be signed for them, and if the elves rice is planted, their names can be included among the participants, but if the profits are generated, it has nothing to do with them."

"Okay." Li Wei'er hesitated for a moment, "I'll try it and see if anyone wants to."
