Erin came back soon after taking out the garbage, and Li Weier looked at her and asked curiously, "Where did you go to dump the waste liquid?" ”

"Right outside, I fell under a tree in the doorway, there's nothing harmful in here, it shouldn't matter, right?" said Erin, pointing out the door.

"No wonder I saw that the tree outside the door had grown much better, because you poured waste liquid under the tree every day. You didn't pour the acid I used in the nutrient solution under the tree, did you? That thing is harmful to the tree. ”

Kaichi looked up at the door, the door of the laboratory was closed, and even if it wasn't closed, he couldn't see the tree at the door.

"Of course not, are you stupid to me, that thing is so corrosive, how can I use it to water the tree, I poured it into the collection tank in the laboratory. ”

The collection tank is not in the laboratory, but outside the bell tower, there is a deep pit about two meters square, which is dedicated to collecting waste from the experiments of teachers and students of the college. There are so many teachers and students in the college, and there is a lot of experimental waste every day, if it weren't for these collection tanks, the waste would be discarded at will, and the whole town would be uninhabitable.

Although there is no such thing as environmental pollution, mages also know that many by-products and waste products from spell experiments are harmful and should not be discarded at will.

However, there are not many collection troughs in the academy, most of them are concentrated near the laboratory area, not in the laboratory, Jiayi still has a little distance from the collection trough in their laboratory, Erin is lazy, and if it is not necessary, he will not go to the collection trough.

Chester finished taking a note and asked, "What happens to the waste collected in these tanks?" ”

"There is a valley on the side of the mountain, and the waste in these collection tanks will be thrown into the valley, and the valley is full of ghost vines and silt monsters, which will digest these wastes and will not accumulate silt. ”

Only then did Jia Yi know that the original college still had this means of biological decomposition, and he didn't know if this thing could decompose plastic and introduce it to the earth, so there would be no need to worry about white pollution, and it would be very profitable to open a garbage dump. When I read the news, I always heard that the landfill was no longer enough, and many garbage trucks secretly dumped garbage elsewhere.

Chester didn't care about the garbage decomposition, but continued to ask, "And if something good falls into it, isn't it gone?" ”

Li Wei'er smiled and said, "It's not strange that you have this idea, someone once searched in the collection tank, and indeed found a lot of materials, and some scrap products that were made and had a little effect, and even found a small piece of Mithril, which made everyone envious at that time." ”

"Mithril, let's go look inside, okay?" Chester said excitedly, his eyes lit up.

He's not here to make money, but to pick up leaks from the garbage, which sounds very enjoyable and exciting. However, it was surprising to find Mithril.

Mithril is generally associated with the silver ore of the rich demons, it is very difficult to refine, light, hard, and many materials can be mixed, it is the metal with the best magic guiding performance, Jiayi they are generally reluctant to use, and most of the transactions of Mithril are usually in the form of Dalan (about 1.8g) and ounces (about 28g).

Jia Yi raised his head from the front of the growth frame and said, "There shouldn't be such a good thing, right? Even Mithril can be thrown away, these people who are experimenting are all local tyrants." ”

Li Weier shook her head: "How can there always be such a good opportunity, after someone found Mithril that time, many people also went to the collection tank to search, and it was originally a drudgery that no one wanted to transfer the garbage from the collection tank to the valley, but it suddenly became a sought-after job, and some people even fought for it." Unfortunately, no one has found Mithril since that time. ”

"If it were me, after this incident, I would carefully check it every time I disposed of the garbage, and I would be heartbroken to death if I threw Mithril away as garbage again. March added on the side.

Li Weier said: "So, basically except for the tasks assigned by the academy now, basically no one goes to the garbage heap to check and pick up the leaks." ”

Picking up leaks in the garbage heap is mainly to enjoy the fun of picking up leaks, if there are too many people, there is no benefit at all, and most of these valuable materials are used very carefully, it is impossible to always pick up.

Even except for the legendary one, no one ever succeeded in picking up the leak since, most of them were some things, and some people began to wonder if the so-called Mithril was really such a thing at that time. After all, time has been a long time, and authenticity is difficult to guarantee.

When everyone said this, Chester still had some ideas, but he didn't mention it anymore, after all, it was not a proud thing for a mage to go through the garbage.

Although in the novels that Jia Yi once read at the starting point, many of the protagonists' first pots of gold were obtained from the garbage heap.

Like our eternal blazing sun, Lucian Evans.

After changing the nutrient solution and using the acceleration circle, the wheat that was originally heading began to bloom at night, and even the flowering period began to pass.

The wheat flowers were obscured by the wheat mang, which was not very visible, and by the evening of the next day, the wheat began to fill the grain.

At this time, it has reached summer, and the weather is relatively hot, so the growth of wheat is relatively rapid, and there is a growth circle, although it is only two days, it is actually equivalent to half a month of growth.

Jiayi, it seems that the tall wheat began to fill the grain so quickly, and he felt that he was not mentally prepared at all, and when he saw that the ears of wheat looked good, he pulled an ear of wheat down.

After he squeezed a grain of wheat with his hand, he suddenly couldn't help but exclaim: "Damn, what's the matter, these grains are deflated." ”

As soon as they heard Jiayi's words, the rest of the people hurriedly put down what they were doing and came to Jiayi's side.

Li Weier said: "What's the matter, is it because of soilless cultivation?"

After all, soilless cultivation is the first time, and there is also a plant growth array, which is inexperienced by everyone, so except for Jiayi, the rest of the people have not completely let go of their doubts about soilless cultivation, although some time ago, these soilless wheat grew very well.

"I don't know, but I don't think so. Jia Yiba handed the ears of wheat in his hand to Li Weier, and continued to rummage in the growth rack, inspecting each ear of wheat, but he didn't pull the ears off.

Although the rest of the people were skeptical about soilless cultivation, Kaichi knew that soilless cultivation was completely fine, the earth had been fact-tested, and he had never heard of soilless cultivation making it impossible to fill wheat.

It is impossible that the lack of nutrition will cause the wheat to be infertile.

The results of Jiayi's examination of the rest of the ears of wheat were not optimistic, and all the ears that produced were not optimistic.

Most of the wheat grains are shriveled, and only a few are a little fuller. Originally, at this time, the ears of wheat should have milky white juice flowing out of the part of the wheat grains when they were squeezed vigorously, but now, very little comes out.

March took the ear of wheat that Gardhorn had come down and looked at it, and said, "Could it be that it is not yet time, because it has not been fully filled?"

"It's not. Jia Yi squeezed another grain of wheat and pointed out to everyone, "Look at this grain is very full, there is a lot of white pulp, but many of them are completely empty, even if they are not fully filled, it should not be like this." ”

When Jia Yi was a child in his previous life, he planted rice at home, and there were also those that did not grow well and had deflated husks, which were screened out with Yang Fan and crushed to feed the pigs.

In other words, Jiayi's current deflated wheat grains are almost impossible to even look down on pigs.
