Doomsday: Unlimited upgrades to the shelter

Chapter 117 Preparing to Upgrade Defenses
Ma Wu thought for a moment, then patted his head with his hands, and suddenly realized, "No, the opponents overlooked one point. They didn't know that we had meteorites. Originally, the power source of this car should be compressed diesel."

"We can replace it with a meteorite. Meteorites already have powerful energy. We can try to use the energy of the meteorite itself to open up the four arms that were originally blocked by self-destruction."

"Although the stars and sparks inside can no longer be used, I can design more powerful weapons, and I will tell you when I design them."

This awesome person had already spoken, Xie Yannan couldn't help feeling as if he had taken a reassurance, and it finally came in handy.

"Then are there any other threats here, positioning devices and the like?"

Xie Yannan was still a little uneasy, something of unknown origin was easily obtained by him, and it was still a high-tech...

"If there is no positioning, the other party is not that stupid. If there is a positioning, then the other party can also be counter-positioned by us." Ma Wu's patience this time is obviously much better than when he first came to Bungu. Perhaps he gradually discovered that Xie Yannan is indeed a comparison. Competent leaders.

Although still in its infancy, it will slowly become stronger.

"Well, then I understand, I'll check it carefully, and put it back in Bungu." Xie Yannan asked everyone to go back to rest, and then he was busy again by himself.

After a while, Wei Xiaofei walked over with a bowl of something similar to Chaos, "Brother Nan, eat something first."

This woman is quite sensible. When a man is doing big things outside, she always has a gentle smile when she comes home, and takes care of everything she can do without any complaints.

"This, is this chaos?" Xie Yannan hadn't eaten such a luxurious food for a long time.

Besides, how can a few big men be so careful to roll out the dough to make chaos, at most the dough and meat will be cooked in a pot in a mess.

Xie Yannan felt more and more that the woman in front of her was extremely cute, took the chaos in her hand, put it on the chair, leaned over and kissed her on the lips.

Playfully, he deliberately buried his head on the right side of her neck, making Wei Xiaofei itchy.

"Brother Nan, what are you going to do?" Wei Xiaofei's face turned completely red all of a sudden, and she deliberately turned her head angrily.

"Hey, I was in a hurry this morning, so I didn't preview my homework. I'm starting to preview now, and by the way, I'll review the evening's lesson together... do your homework!"

"Hey, the door is open..."

……

Xie Yannan's physical function is indeed extraordinary, but Wei Xiaofei is not weak as a second-order human being now. After the two of them exercised a lot, Wei Xiaofei was obviously more out of breath than Xie Yannan.

"Take your time, I'll continue to take care of the vegetables." Wei Xiaofei shyly got out of the car.

"Phi, slow down."

Xie Yannan breathed a sigh of relief, and then continued to check the inside of the car carefully, and after confirming that there was no problem, he and Xiaoxiao drove it back to Bengu.

After returning to Bungu, the first thing Xie Yannan wanted to do was to store all the dry goods stored in the system into the storage room in the basement.

This time, Xie Yannan was more careful, adding password identification to the storage room, food storage room, and weapon arsenal.In other words, not everyone in the valley can enter.

The identification method is a biometric device, only he and Wei Xiaofei can enter.

He has [-]% trust in Wei Xiaofei, a woman who is willing to risk her life to save him.And when he was away, she had to rely on her to manage and distribute supplies.

As for Xiaoxiao, he trusted her at first, but after knowing that Ma Wu participated in her production, he felt a little more vigilant for no reason.This man made Xie Yannan feel scary no matter his knowledge or ability, so he had to take some precautions.

In fact, these defenses are just self-deception. For such a powerful person, these are nothing to him.

[The system has automatically turned on the storage function]

Xie Yannan took all the things out on the ground, and then put them neatly in the cabinet in the same way.

This bumper harvest is all with a shelf life of more than half a year.Even if all the food and water sources grown outside were cut off, these rations would still be enough for them to survive for more than half a month.

Xie Yannan was a little worried when he thought that the filter element of the warning purifier before the system was almost used up.Moreover, the cooling of this cold wave was even worse than he had imagined. Although the water source was diverted from the bottom of the stream, only the surface of the stream was frozen.

But because the temperature is too low, the pipes are more or less condensed, resulting in very little water in Pengu today, and it can only barely maintain the operation here.

It seems that it can't go on like this, and it can't rely on external water supply. It's better for the basin itself to form a simple water circulation system.

He has read it in the system before, and the system itself no longer provides new filter elements, so the purifier can no longer be used. The biggest problem at present is to set up Pengu's own water circulation system, and to maximize the Filter drinking water well.

The water in the pond is enough at present, mainly to filter the daily domestic water.

Xie Yannan doesn't plan to abandon the route of the stream, but it's not the most important one. That route is only used as emergency water.

distilled water?These words suddenly popped up in Xie Yannan's mind.

After all, the most abundant thing in the system now is meteorites, and what meteorites can provide is energy, and what is most needed for distillation is sufficient heat.

Although he can't guarantee the heat, he can use other equipment to indirectly convert the meteorite's ability into heat, so that he can provide a steady stream of heat for the time being.

Xie Yannan thought of this, and suddenly remembered that the plasma polymer identifier in his hand hadn't been properly installed. After installing it first, he could feel that it would be better to install the distillation equipment.

"Uncle Ma, come and help me take a look." Xie Yannan yelled at Uncle Wei's cave.

His original plan was to use this thing that looked like sugar cubes, and after being processed by an amplifier, it would be able to surround the basin valley and even the top for a week, so that the entire basin valley could be tightly sealed.

Its principle is indirect concealment, which seems to be tightly closed.In fact, even if something else breaks into the thing, it can change its path like the previous three-level shelter and let it fly directly to other places.

And once the formula is designed, once those who don't meet the conditions can't break in at all, it's like a wall in front of them.

Xie Yannan had seen the power of this thing before, and he definitely did not exaggerate its function. It was just that it was inconvenient to take away the energy amplifier because of the system at that time, so now he didn't know how to realize such a grand plan in his mind.
