Erin came back soon after taking out the trash. Li Weier looked at her and asked curiously: "Where are you going to dump the waste liquid? Why are you coming back soon?"

"Just outside, I fell under the tree at the door. There was nothing harmful here, so it shouldn't matter?" Erin pointed out outside the door and said.

"No wonder I saw that the trees outside the door grew much better. It turned out that you poured waste liquid under the tree every day. You didn't pour the acid liquid I used in the process of mixing nutrient liquid into the tree, right? That thing is harmful to the trees."

Jia looked up and looked outside the door. The laboratory door was closed. Even if it was not closed, he could not see the tree at the door.

"Of course not. Do you think I'm stupid? That thing is so corrosive, how could I use it to water trees? I poured it into the collection tank of the laboratory."

The collection trough is not inside the laboratory, but outside the bell tower, there is a deep pit about two meters square, which is specially designed to collect waste from the experiments of teachers and students of the college. There are so many teachers and students in the college, and there are a lot of experimental waste every day. If it weren't for these collection troughs and the waste was discarded at will, the entire town would not be able to live.

Although there is no concept of environmental pollution yet, the mages also know that many by-products and wastes during spell experiments are harmful and cannot be discarded at will.

However, the college does not have many collection tanks, most of which are concentrated near the laboratory area and are not in the laboratory. Jiayi and his team have a little distance from the collection tank in the laboratory. Erin is lazy and doesn't go to the collection tank if it is not necessary.

Chester finished a record and asked, "How will the waste collected in these collection tanks be disposed of? Do you think anyone will accidentally throw the good stuff into it?"

Li Weier said: "There is a valley on the mountain on one side. The waste in these collection troughs will be thrown into the valley. The valley is full of ghost vines and mud monsters. They will digest the waste and will not accumulate."

Only then did Jiayi realize that the college also had this kind of biological decomposition method. He didn't know if this thing could decompose plastics and introduced it to the earth, so he didn't have to worry about white pollution. Opening a garbage dump would be very prosperous. When I read the news, I always heard that landfills were not enough, and many garbage trucks secretly dumped the garbage elsewhere.

Chester didn't care about the decomposition of garbage, but continued to ask: "If something good falls into it, isn't it gone? What a pity."

Li Wei'er smiled and said, "Your idea is not surprising. Someone once searched the collection tank and found a lot of materials, some scraps made with some useful effects. She even found a small piece of mites, which made everyone envious."

"Mstr.! Let's go inside to find out if it's good?" Chester said excitedly.

He came not to make money, but to pick up bargains from the garbage, which sounded very satisfying and exciting. However, it was also very surprising to be able to find Mitsunami.

Mithril is generally produced in the silver ore of the rich man. It is very difficult to refine, it is light and hard, and can be mixed with many materials. It is the metal with the best magical conduction performance. Kazuichi and others are generally reluctant to use it. Usually, Mithril trades are mostly made of tart (about 1.8g) and ounces (about 28g) as units.

Jiayi raised his head from the front of the growth rack and said, "There shouldn't be such a good thing? Even Mitsun can be thrown away. These people who do the experiment are all rich people."

Li Weier shook her head: "Why are there always such a good opportunity? After someone found the Misinian that time, many people went to the collection trough to search. It was originally a chore that no one wanted to transfer the garbage from the collection trough to the valley, but suddenly it became popular, and some even fought for this matter. Unfortunately, no one found the Misinian again."

"If it were me, after this incident, I would carefully check every time I deal with the garbage. I would throw away the Mitsunian as garbage again, which would make me feel heartbroken." Maggie added.

Li Wei'er said: "So, now, except for the tasks assigned by the college, there are basically no one going to the garbage dump to check and find a bargain."

Picking up bargains in the garbage dump is mainly to enjoy the fun of picking up bargains. If there are too many people, there is no benefit at all. Moreover, most of these precious materials are very careful when used, and it is impossible to pick them up all the time.

Even except for the legendary one, no one has ever successfully picked up the bargain. Most of them were rags. Some people began to wonder if it was really true that the so-called picking up Misin was so called. After all, it has been a long time, and it is difficult to guarantee the authenticity.

After everyone said this, although Chester still had some ideas, he never mentioned this matter again. After all, for the mage, going through the garbage is not a proud thing.

Although Jiayi once read in Qidian, many of the protagonists' first pot of gold were obtained from the garbage dump.

Just like our eternal fiery sun Lucien Evans.

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

The wheat flowers were covered by the wheat turtle, and it was not very clear. By the next night, the wheat began to grout.

It is already summer this time, and the weather is quite hot, so the wheat grows more rapidly. In addition, there is a growth array. Although it has only been two days, it has actually been half a month since it has grown.

Jiayi, it seemed that Gaomai started filling grout so quickly, and she felt that she was not mentally prepared. Seeing that the wheat ears looked good, she pulled down one.

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

As soon as he heard Jiayi's words, the rest of the people quickly put down their things and came to Jiayi's side.

Li Weier said: "What's going on? Is it because of soilless cultivation?"

After all, it is the first time for soilless cultivation, and there is also the cooperation of plant growth arrays. This is something that no one has experienced. Therefore, except for Jiayi, the others have not completely let go of the doubts about soilless cultivation. Although these soilless cultivation wheats grew very well for a while ago.

"I don't know, but I think it's not." Jia Yiba handed the wheat ears in his hand to Li Wei'er, and continued to search in the growth rack, checking each ear, but it didn't pull it off.

Although the rest of the people have doubts about soilless cultivation, Jiayi knows that soilless cultivation is completely free. The earth has been tested by facts and has never heard that soilless cultivation will prevent wheat from being filled.

It is impossible that insufficient nutrition will lead to infertility in wheat.

Jiayi's examination of the remaining wheat ears was not optimistic, because all the wheat ears that were born were not optimistic.

Most of the wheat grains are shriveled, and only a small part is a little fuller. At this time, the wheat ears should have milky white juice flowed out of the part of the wheat grains, but now, very few of them flow out.

Machi took the ear of wheat that Jia had dropped and looked at it, saying, "Is it because it has not yet reached the time and has not been fully grouted?"

"No." Jiayi squeezed another grain of wheat and pointed it out to everyone, "It looks very full, with a lot of white slurry, but many of them are simply empty. Even if the grout is not sufficient, it shouldn't be like this."

When Jiayi was a child in his previous life, he planted rice at home. Some of them were not well-deep. They were screened out using Yang Fan and crushed them to feed pigs. Later, the living conditions of the pigs also improved. The rice bran from simple shredded rice was not eaten. They had to be mixed with rice bran from good rice, but they were actually mixed with rice flour.

In other words, Jiayi's current deflated wheat grains are almost not even favored by pigs.
