Xu Xin immediately returned to the tree house and started the electric water pump.

There was a buzzing sound, and within a few seconds, the electric water pump pumped water into the tree house.

Not knowing how long the snowy weather would last, Xu Xin began to store water.

He built large buckets one after another, pumped the water up, filled the buckets, and saved the extra space stacked on the first level of the tree house.

Soon, the first floor was filled with water.

These should be enough.

The small screen on the electric water heater lights up and displays two numbers.

A percentage, a temperature.

The percentage is obviously the capacity, which is increasing rapidly. The temperature shows 6°C.

After more than ten seconds, the electric water heater capacity showed 100%, and the water pump automatically stopped pumping water.

Xu Xin started the water heater, and the temperature display also slowly increased.

Not bad, comfortable!

He connected the water pump to the toilet's water tank, and connected the drain outlet to the pipe, and connected it to a deeper place under the tree house for discharging sewage.

Does this count as fertilizing the treehouse?

Then, Xu Xin equipped each room with electric lights, and then made an electric oven and range hood, making the kitchen more presentable.

After finishing everything, Xu Xin returned to the third floor, sat down heavily on the sofa, and breathed a long sigh of relief.

His tree house seems to be self-sufficient, and he feels like he can live forever without leaving home.

Is this what Fortress of Doom feels like?

Weapons, energy, food, he has them all, and they are very abundant.

This feels really good.

After doing this, it was getting a little dark, and the other members of the [Explorers] had also returned to the tree house one after another.

Xu Xin also immediately started to configure the power grid for them.

Ji Chaoyang had also returned to the tree house, and Xu Xin directly gave him the copper block.

He can also unlock the blueprint, so Xu Xin doesn't need to take care of it, he can just make it himself.

At the same time, everyone on the regional channel had begun to feel a little uneasy.

Because they could already clearly feel that the temperature outside the tree house was dropping.

Indeed, during the day, the temperature is still six or seven degrees, and it can even reach around ten degrees at noon, but when it gets dark, the temperature is already close to zero!

"Oh my God, it's really like what the boss said, it's going to be a cold winter!"

"Fortunately, the bosses let us build the fireplace in advance and let us cut down more trees. My current wood reserves are enough for me to burn for a long time."

"I have cut down all the trees around me, and I have destroyed several axes! There is enough energy, and I feel very at ease."

"Why don't you feel reassured! Didn't the big guys say that there will be another wave of beasts tomorrow?"

"I have already bought four repeating crossbows. When the time comes, if any wild beasts dare to attack the tree house, I will shoot them!"

"Four? Can I buy four? Damn it, I only bought two?"

"Finally, I have meat to eat. I'm so hungry. And it's so cold now, so it will last a long time. It's so comfortable!"

It seems that everyone in District 188 is basically ready.

Without a control panel and power grid, their survival rate is definitely much lower than that of them [explorers].

But there is no way to provide them with information and sell them the new type of repeating crossbow. They [Explorers] have done their best.

There should be a lot of saltpeter mines dug by Li Wenxi today, and some of them can be supplied to ordinary survivors.

Soon, Xu Xin configured the power grid for everyone in the [Explorer] and even made the electrical appliances they wanted.

Zhao Xiaochuan: "I am really confident now to resist tomorrow's beast tide! Control panel, crossbow with explosive crossbow bolts, and high-voltage power grid, who can break through my defense! Neither Brother Xin nor Brother Chaoyang can do it!"

Li Wenxi: "How much juice from mutated vines have you collected? I have more than 10,000 kilograms of green-grade saltpeter here."

Wang Lei: "What?! More than 10,000 kilograms?!"

Li Wenxi: "Oh, there are many people here, and Xu Xin asked me to dig more, but I accidentally dug too much."

Xu Xin was also shocked.

He immediately looked at the blueprints for making explosives.

[Small Explosives (Green): Small Explosives will explode upon impact. They are very powerful and can be used to make explosive arrows and explosive crossbow bolts. Small Explosives (Green)*20 require vine sap (Green)*1kg, Saltpeter (Green)

)*2kg, charcoal (green)*20]

Twenty small explosives, that is, twenty explosive crossbow bolts, require 2kg of saltpeter. In other words, more than 10,000 kilograms of saltpeter. If the vine juice is enough, one hundred thousand explosive crossbow bolts can be made!

With so many explosive crossbow bolts, they can share some with others to improve their survival rate.

but……

Xu Xin checked her vine juice.

Although he hunted more than a hundred powerful mutant vines, and the vine juice each one could obtain was several times that of ordinary vines, but even so, plus what was left before, he only had more than 800 in his hands.

Kilograms of mutant vine sap.

To make 100,000 explosive crossbow arrows, at least 5,000 kilograms of vine juice are needed!

Xu Xin: "I only have more than 800 kilograms of vine sap."

Wen Guixin: "I have 2,300 kilograms in my hand now."

...Two thousand three hundred kilograms?

Xu Xin raised his eyebrows. Although he was a little surprised, he was not surprised.

After all, it's Wen Guixin who has the ceiling of combat effectiveness.

Other members also revealed the weight of the vine juice in their hands.

A total of just over 4,000 kilograms.

However, it is enough.

At this time, Ji Chaoyang, who had been silent, spoke up: "I'll go to the regional channel and ask. Apart from us, there must be some capable people who can kill the blood-striped vines."

Sure enough, after Ji Chaoyang's inquiry, several survivors said that they had vine juice in their hands, but they didn't know what it was used for.

Xu Xin and Ji Chaoyang immediately chatted with them privately and told them that these were raw materials for making explosives. They could exchange them for the prepared explosive crossbow arrows, and easily exchanged all the vine sap.

After all, this thing is useless in their hands.

Ji Chaoyang: "Give me all the materials and I will make them. My production room has an increase point of 150%. You probably don't have as many as me. There is a chance that the production room will reduce material consumption."

Xu Xin's production room only had 100%, so without saying anything, he directly traded all the vine juice.

Wang Lei: "Damn it, Brother Chaoyang has more growth points in one production room than I do in total!"

Wen Guixin: "I'll give it to you."

Li Wenxi: "Shall I give it all to you?"

Ji Chaoyang: "No, give it to me in batches. It's too much for me."

At this time, the teleportation array outside Xu Xin's tree house suddenly made a harsh sound, and the teleportation exit opened.

After Lou Fei'er came out of the teleportation exit, she fell directly to the ground. She stood up shakily and went directly into the small wooden house next to her.

A minute later, she came out of the cabin with a satisfied smile on her face. The two blood streaks had not receded yet.

She was not shocked by the high-voltage power grid, because she had just helped Li Wenxi lay out the power grid at Li Wenxi's side.

"Xu Xin has circled such a large area, my God, there is also a swimming pool?" She was shocked by the newly opened pool on the ground, "How can you enjoy it?"

Because of the enhanced hearing, Xu Xin could hear Lou Fei'er's words and immediately rolled her eyes.

Lou Fei'er did not go to Xu Xin again. She was tired after digging for a day and wanted to go back and rest.

Finding the door, she reached out and pushed it open.

"Crack!"

"ah!"

Xu Xin heard electric shocks and screams coming from outside.

He looked out of the window and saw Lou Fei'er lying next to the power grid, her body shaking.

He quickly got down from the tree house and walked to Lou Feier's side.

Lou Fei'er was still shaking slightly, her eyes had turned a little white, and the blood lines on her face that appeared in the cabin had become very faint.

Xu Xin quickly squatted down and helped Lou Feier up.

Lou Fei'er had regained consciousness at this time, and when she saw Xu Xin, she burst into tears: "Wow! Why... why did I get electrocuted... Wuwu... I dug mines for a whole day...
