Xie Yannan lay on the bed, quietly waiting for the system to finish processing.

Just now I could hear the sound of the laboratory machines not far away, but suddenly it disappeared.

He sat up and stretched, the effect was enough for him and Wei Xiaofei.

The system also stores stainless steel used to make the greenhouse heat pump system. Although Xie Yannan felt a little tired, the sky was getting darker and the temperature dropped more significantly, which did not leave him enough time to rest.

He came to the vegetable greenhouse again without stopping.

The rapeseed in the greenhouse has begun to mature, and it should be harvested in another week to be used for extracting rapeseed oil.

Although they now have a variety of vegetables, except for a little bit of stocked beef, the food they eat has basically no oil.

If the rapeseed is ripe, squeeze out the diesel oil, and then you can stir-fry vegetables like normal stir-fried vegetables.

【System processing...】

Regarding the length and diameter of the heat pump system, Xie Yannan had already planned it in his heart. The vegetable greenhouse was originally very small, and it was directly made to be 6.7 centimeters. The compressed air inside is enough to dissipate the heat.

In terms of length, it is better to be slightly shorter than the greenhouse. The four pipes overlap and are arranged in this way around, which is completely enough to provide heat.

Xie Yannan thought for a while, now that everything to keep out the cold is ready, he should call Uncle Wei and Uncle Ma to plan the attack on the third-level shelter.

According to the character of the people there, even if Xie Yannan didn't take the initiative to attack, he would be surprised by the other party, and he himself would not be able to do it at all.

Because it was getting late and the weather was cold, the two middle-aged men had already nestled in the cave to rest.Xie Yannan gently climbed up the rock, if they fell asleep, he planned to come back tomorrow morning.

A short sleeve inside and a cotton coat outside made him feel the biting cold wind.

Moreover, the road surface has begun to frost, and it is a bit slippery to walk on.

Just before reaching the entrance of the cave, I heard Uncle Ma and Uncle Wei arguing, and there seemed to be some serious disputes.

Xie Yannan was a little curious, usually on the surface, the relationship between these two people is good, why do they feel like enemies behind their backs.

"Why don't you tell Wei Xiaofei that I am her father..."

This is Uncle Ma's voice.

This... This amount of information is too much, Xie Yannan couldn't help but widen his eyes and prick up his ears to listen.

"It was you who left Xiaofei's mother and ran away. I raised her, so what's the matter with her calling me daddy? Besides, she knew the truth and didn't want to acknowledge you on purpose."

Uncle Wei is not to be outdone.

It turns out that there is a lot of fame here, no wonder when Xie Yannan mentioned Wei Xiaofei back then, he did not hesitate to follow back to Pengu.

"..."

"..."

The two of you said one sentence to another, and said a lot of cursing words, and then there was no movement.

Xie Yannan stood on the side for a while, then went into the cave, "Uncle Ma, Uncle Wei, I have something to do, I need to trouble you."

Regarding everything he just heard, even if Xie Yannan's emotional intelligence was not that high, he knew that he should pretend not to hear it.

"Oh, you said..." Uncle Ma sighed, motioning for Xie Yannan to sit on the stone bench next to him.

"That third-level shelter broke through the doomsday underground mall that I used to exchange things for, and also occupied the steel market. I decided to take the initiative and take them down, or they will come and take our shelter sooner or later."

Xie Yannan knew very well in his heart that the reason why the other party hadn't come yet, but just sent scum like Wang Hui to die, was nothing more than thinking that Xie Yannan's shelter didn't have what they needed, no food, no weapons, no raw materials. There is no need to work hard to attack it.

"Are you going to destroy that shelter?"

Uncle Ma understood it, and asked directly and violently.

As he spoke, he took out a blank sheet of paper from his backpack, "I designed that shelter, and all the drawings are on it."

"However, this is only a floor plan, and the scale of the later construction may be slightly different from the actual one."

Xie Yannan took the drawing and looked at it. It was clearly a piece of white paper. "There's nothing on it?"

"You can just shine it with your ultraviolet light. It is painted with white fluorescent light, in order to prevent criminals from taking advantage of it."

Uncle Ma said criminals, and gave Uncle Wei a meaningful look, but Uncle Wei only designs weapons, and he really doesn't have much to talk to about these things.

Xie Yannan saw that the above was indeed similar to the situation of the entire refuge that he had seen before, but it was just a shriveled floor plan, which was useless at all, "You... No, Uncle Ma, I'm just thinking about how to make it better. Alright go in, take it, grab my supplies, and get out intact."

Because that door was so advanced, Xie Yannan was a little bit worried.

"To get in, you can only go in according to the other party's method. When I designed this molecular identifier, the rules were already fixed. In order to put an end to the sophistication of the world, the person in charge only had to enter hard, and there was no such thing as a hard break."

"Then, you go to the bottom where you entered, and there is a hidden manhole cover. Under the manhole cover is the switch of the molecular identifier. If you turn it off, the entire wall becomes a real wall, and no molecules will be released. Read the data, no one can get in or out that way."

Ma Wu still knows what he designed.

"Uncle Ma, what you said is not right. You asked me to open the door to the basement under my feet in public. I'm afraid I can't do it."

This is indeed a big loophole, he has no idea how many people there are in that shelter, or how many weapons there are, even Xie Yannan doesn't know.

"Because it's very public, this problem is a bit tricky. It was designed in this way to prevent others from making trouble. But there is another way, that is, you first destroy their power system. Once the system does not supply power, then their The surveillance won't work, the entire shelter is dark, and you can do whatever you want."
