When the car door opened and the eyes of both sides met, Wu Yu was frightened on the side, but the expected collision between heaven and earth did not happen.

"You... are Sister Linlin?"

"...Sister Xianya!" Linlin smiled sweetly, as if the pain in front had never happened.

Wu Yu was confused. What's going on? Shouldn't the two of them immediately be in chaos when they met? Why did they come here to Jinlan?

Can you still enjoy the blessings of all people?

The two were extremely close, like a good friend I hadn't seen for many years, holding hands and chatting endlessly. Wu Yu completely became a foil, decoration, and background character.

"Oh! Today is Linlin's birthday, so I have to celebrate it! Let's go home with me, cook two dishes for you, and give you a bowl of longevity noodles."

"Ayu! Drive!" Yu Xianya finally remembered that there was someone like Wu Yu around her, and immediately treated him as a driver.

Wu Yu drove the car, as if he was pulling a truck of nitrifying glycerin, and was trembling. He neither dared to speed up or brake casually, for fear that he would cause a big explosion if he accidentally caused.

When they got home, the two women walked into Wu Yu's villa with a familiarity. Yu Xianya was familiar and Zhang Ruolin was also familiar...

Wu Yu was very surprised to find that there was no smell of gunpowder between the two women. They were as good as their own sisters, with a charming smile and bright eyes. One smiled so sweetly, and the other smiled gently and charmingly. The air was filled with a harmonious smell. Everything had such a main theme, and there was no negative energy.

Next, Yu Xianya cooked, and then Zhang Ruolin was not willing to be outdone. The two of them made a very rich table of dishes, which looked both colorful, fragrant and delicious. I don’t know what they tasted, but they looked very good.

"Ayu! Try the udon noodles made by me!" Zhang Ruolin clothed a little dish on Wu Yu's plate.

"Ayu! Try my Milan kiss!" Yu Xianya also served some dishes to Wu Yu cloth.

"Ayu! Try my cinnamon apple pie!"

"Ayu! Try my Hainan chicken rice!"

......

After a short while, the plate in front of Wu Yu was filled with various dishes.

"Is it delicious?"

"Delicious! Delicious!"

“Who’s the better one?”

"Everything delicious! All delicious!"

"Since it tastes good, eat more of mine!"

"If you like it so much, eat more of mine!"

Finally... Wu Yu's heart was finally relieved, and he was not up or down. Now he felt the smell of gunpowder... It's really not easy!

"Sister Lin, today is your birthday. I have prepared a birthday noodles for you. You must finish them all. People say that if you don't finish them, you will lose your birthday."

As he said that, Yu Xianya brought out a bowl of very affordable birthday noodles. Judging from the amount, Wu Yu probably couldn't even eat it. Then he looked at Zhang Ruolin. Seeing that big bowl of birthday noodles, his smile almost deformed...

"We are considered a live broadcast of palace dramas?" someone in the surveillance team said.

"No, at most, it's a two-female fight for husbands. If you come here two or three, you can get together a table of mahjong and be considered a palace fight."

"How come I feel depraved?"

"Hmm? What does it mean?"

"The secret service department has become a housework handling center..."

............

When Wu Yu was at a loss for food at the dinner table, Meng Yang was communicating with G4.

"G4, what's the current situation of thermocoagulation plants?"

"Report boss, everything is normal for hot alfalfa, plenty of water, and normal heat conversion."

"What is the temperature in the space?"

"It's basically constant around 17 degrees Celsius."

“How is the current energy revenue and expenditure?”

"The energy input mainly comes from two pieces, electricity mainly supplies biological lighting consumption, and geothermal heat is responsible for maintaining the oxygen cycle. At present, energy revenue and expenditure are basically balanced, and no signs of temperature out of control are found."

"How is the matter cycle?"

"Currently, the carbon dioxide cycle time is 52 hours, the carbon dioxide concentration is gradually decreasing, the air humidity is increasing, and the enrichment of methane and ammonia is detected in the air."

"Ammonia enrichment?" This is a new situation.

"Because those cows get cow shit everywhere, the cow's urine is spread throughout the space, causing the ammonia content to rise and the methane concentration to rise. Currently, the pH value of the water body in the space is moving towards the alkaline end." G4 reported to Mengyang.

Well, from the beginning, I knew that things were not that simple. After only a few days of running, there was a problem. Meng Yang could already imagine the living environment of those cows living in G4. He must wake up with his own smell of shit and urine every day, and then fall asleep in the smell of shit and urine...

“…How is the natural corrosion process of feces and urine going on?”

"It's not good. If you wait for the bacteria to naturally corrode and let these feces and urine re-enter the biological cycle, it may take at least one month, and this will further release more methane and ammonia, and at the same time produce a large amount of nitrates, sulfates, carbonates, various dense rings, steroids, and polypeptide substances. These substances cannot be absorbed and digested by thermocoalfa. If you want these substances to re-enter the ecological cycle, you may need to add new biological species."

Can't handle it...

Sure enough, there are only two main creatures in the biosphere that cannot be done.

"There are some garbage decomposition grasses on the surface. They are specifically responsible for decomposing and converting waste such as feces and absorbing excess ingredients in the air. They exist as oxygen-consuming vegetation."

"Boss, how to solve the increase in water pH?"

"Release some garbage and decompose the algae in, and let them be responsible for filtering and cleaning up water pollution."

"yes!"

Meng Yang's solution is a bit simple and crude. If complex decomposition and corrupt bacteria in nature are introduced, then a large number of various bacteria must be introduced, and the decomposition cycle speed will not be increased much.

G4 may not be able to wait for such a long time. After this period of delay, G4 becomes a toilet.

Simply introduce garbage decomposition plants and algae directly, and solve the problem of decomposition and then recycling of feces and urine in one go. At the same time, there are also solutions to the animal corpses you will face in the future.

"Boss, the humidity in the space is increasing, how to solve this problem?"

There is no rainfall and no temperature difference in the G4 space, so the water circulation cannot be established. If the water vapor enters the air, it is difficult to have the chance to condense again. The air humidity is increasing and it is now approaching saturation.

“Is there any adverse effect?”

"I haven't seen it yet, but fog has begun to appear in the G4 space, and there is a gradual increase."

"Since there is no adverse effect, then let it go first and put it aside for the time being." Meng Yang thought for a while, and did not take the initiative to allow the space to maintain a high humidity.
