As for the other one who is very interested in the construction of the academy, it is Guo Dacheng, a master mechanic.

In the eyes of this group of students, livestock are raised for people to eat, as long as they keep their rations, and as for the shed, as long as it can shelter from the wind and rain.

However, the students' primitive and crude idea was immediately rejected by Guo Dacheng, you must know that in the neutral school district, livestock breeding has long been fully automated, and there is no need for people to take care of it.

Of course, the Three Killings Academy can't be compared to a neutral school district after all, but since he is here, it is impossible to watch those lovely rations being locked up in such a humble place and growing, and then being slaughtered in pain!

Therefore, Mr. Guo, who is a professional counterpart, personally took the students to the city to purchase a large number of new building materials, preparing to build a strong, warm and dry all-metal indoor ranch.

Lin Zhuosheng, who was trembling with pain and pain looking at the bill, turned his head to look at Li Yiyi, and Li Yiyi turned around to wipe the shelves, but he didn't see it.

She has already spent a lot of money on a college now, and this little matter should be solved by the principal of Lin University.

Although it is a lot of investment to build livestock, oh, it is a new type of indoor ranch, but when half a month later, a mushroom-shaped metal building covering an area of nearly two acres and twenty meters high appeared in front of the teachers and students, they still let them stand in place and did not ease the shocked emotions for a long time.

Li Yiyi was also shocked at this time, wow...... Luo Meiren really found a treasure this time, this Guo Dacheng is amazing, it's just a livestock shed, and it's like a science and technology building.

Subsequently, Guo Dacheng took all the teachers and students into the interior and briefly introduced some of the facilities inside.

Livestock... No, it's a pasture, and the first thing that catches my eye is a large open space, about half an acre of land, Guo Dacheng Guo pointed to this open space and said:

"This open space is an important source of food for livestock, and there is a warehouse next to it, so that in the autumn, students can put the dried grass in this baling trough, and the machine behind the warehouse will break the grass and compress the grass, which can also be convenient for the students to organize."

This Li Yiyi said that he was not surprised, after all, there was also this kind of technology before the end of the world.

Then Mr. Guo led everyone to the end of the pasture area.

"You see, in order to save space, this should have been a whole wall, but now I have converted it into a poultry breeding area, so that we can increase the variety and quantity of breeding and save land occupied area.

And after the eggs are laid, the birds will be directly packed in different egg trays according to the size along this electric conveyor belt, ah, I also placed an ultraviolet sterilization bin in the middle of the conveyor belt to ensure that each egg is perfect and sterile. ”

Well, this kind of poultry farming she has seen in the agricultural station before, it is not a novelty.

"After the poultry area, there is a large livestock breeding area, and everyone looks at the ground inside the fence."

Everyone followed Mr. Guo's finger and looked at the ground, only to see that the lower part of all the fence intervals was actually connected.

And there was also an inner triangular metal bar that ran through the fence against the ground, and Li Yiyi felt as if she understood what it was about.

"Look here, here, it's a unified manure cleaning device.

The time required for cleanup can be adjusted according to the actual situation.

There is also an automatic monitoring device that automatically stops the return if a domestic animal stops it.

This also ensures that the livestock do not destroy the cleaning unit in anger. ”

Damn, isn't this just a copy and paste of the concept of a fully automatic cat litter box before the end of the world.

"Of course, some students will definitely ask, where did the cleaned feces go, come with me.

Everyone followed Mr. Guo towards the back door of the livestock area, and when they walked here, the entire ranch had come to an end, and out of the back door was an ordinary flat land, but Mr. Guo pointed to the iron gate on the ground similar to the cellar and said:

"Ladies and gentlemen, please see, this is an underground biogas digester, and the cleaning device pushes the manure of livestock onto the manure conveyor belt behind it.

The manure then falls on the digester with the conveyor belt, and after a certain period of fermentation, the concentrated manure produces biogas.

Don't underestimate this biogas, it's a very environmentally friendly energy source.

As for what biogas can be used for, it can be used to make a fire, such as cooking in a canteen, and there is no need to chop wood to make a fire in the future, and you can directly use biogas to obtain a fire source.

In addition, it can also be used to boil boilers and boil water, so that in winter, students don't need firewood to burn the kang, and they don't need to boil water when taking a bath. ”

Li Yiyi and Luo Meiren glanced at each other, and Luo Meiren received Li Yiyi's doubts, but Luo Meiren stretched out his thumb to Li Yiyi with a serious expression.

"How? This Mr. Guo has two brushes. ”

"I'm hehe!"

Li Yiyi's eyes widened, trying to control his facial expressions to keep himself from laughing.

It turns out that the mechanical master hundreds of years after the end of the world, is this level?

And what's going on with the Romes, didn't you grow up under the influence of pre-apocalyptic civilization? Why don't you even know anything about this pre-apocalyptic commonplace?!

However, no matter how Li Yiyi complained in his heart, the students seemed to eat this set, especially when they heard Mr. Guo say that there would be hot water bathing at any time in winter, and the students, especially the girls, had a look of extreme excitement and anticipation on their faces.

Forget it, it's good for the students to be happy, and it's good to understand some things themselves, but there is no need to say it, which will not only discourage the enthusiasm of the students, but also give birth to a kind of class contempt and hatred of the rich in their hearts.

It's so unfair to them who are still learning.

After another two days, the students had already ploughed the vegetable patch, and Li Yiyi handed over the fruit and vegetable seeds and saplings that Stephen Xiang needed.

On the other hand, the indoor ranch does not have as much energy to take care of a large number of livestock due to the limited number of students.

So Li Yi placed two goats, four cows, four oxen, six pigs, thirty ducks, fifty chickens, twenty rabbits, twenty grass carp, crucian carp, fathead fish, shrimp, and crabs in the huge pasture.

Even if there are not many types, once they add up, it is not so easy to raise, and now Li Yiyi really admires Guo Dacheng for building this indoor ranch, which really makes the students have enthusiasm and will not consume too much learning energy because of this.

Li Yiyi instructed the kitchen to add food to Mr. Guo that night, which was regarded as thanking him for his practical contributions to the school.

However, the last time Mr. Guo said about the problem of water in winter, Li Yiyi thought that when the students were building the dormitory, they only had rooms for people to sleep, and the cafeteria was only thought of by Luo Meiren's reminder, and as for the toilet, it was simply built outside the dormitory.

Although he didn't worry about safety, it was still not very convenient in the end, so Li Yiyi told Lin Zhuosheng about it, Lin Zhuosheng nodded, and decided to take advantage of the students' summer vacation to let them cover the indoor toilets and bathhouses.
