Doomsday: Unlimited upgrades to the shelter

Chapter 230 Defense Umbrella
"What do you mean, aren't you going back?"

Xie Yannan was a little confused.

Does Ma Wu mean that he is temporarily staying here?
"I want to study. The simple drawings drawn by hand are not enough, and I need a very quiet environment. There is no need for other useless people to be here."

Useless people? !

Xie Yannan secretly glanced at Wei Beiming, only to see that his face became extremely ugly, but he didn't say a word.

After all, Ma Wu's ability is indeed far above him.

"No, you are not safe here. If there is any monster coming out of this thing, you can't deal with it at all."

Xie Yannan has long seen that Ma Wu is really good at talking on paper, but he has no actual combat experience, and everything is limited to talking on paper.

"No, didn't you give me a meteorite? I also took away the mobile phone in the shelter. If there is anything, I will tell you."

Ma Wu still insisted on staying alone.

But since this refuge has not been disturbed by outsiders for so long, and there are no traces of monsters, it should not be so vulnerable.

"Alright then, call me anytime you need anything."

Xie Yannan is worried about both Ma Wu's comfort and his character, after all, he is still the most mysterious person in the entire shelter up to now.

Before leaving, Xie Yannan put a little more thought into installing a hidden camera in the corner of the weapon base using the system.

Finally, I checked again and found that there was no other abnormality in the entire shelter, so I left with confidence.

Wei Beiming kept his expression serious and didn't talk to him.He is an expert in disaster prevention weapons, and he is not familiar with such offensive weapons at all, so he just followed Xie Yannan's arrangement to come and have a look.

"Uncle Wei, Uncle Ma speaks a little bluntly, so don't take it to heart."

Since Xie Yannan is the leader of the refuge, it is still necessary to comfort his subordinates.

"I'm fine." Wei Beiming was always a little serious, not knowing what was going on in his heart.

When he returned to the shelter, he brought Xie Yannan to the garment factory, pointing to the two umbrellas produced on the ground, "I have improved this umbrella, although it cannot be used as a very good heavy weapon, it is no problem for ordinary defense .”

Xie Yannan did not expect that some time ago Wei Beiming wanted the right to use the garment factory for himself to make umbrellas.

"This...should be just an ordinary umbrella, right?"

Xie Yannan picked up one in a daze, only to realize that the umbrella was a bit heavy, it should be five or six times the weight of an ordinary umbrella.

But because the umbrella handle is made of two curved hooks at 180 degrees, it is effortless to hold it in your hand.

"It's not an ordinary umbrella, try it."

Wei Beiming just smiled faintly, moved his right shoulder, and took out a bow and arrow from the backpack on his back. This is a wooden bow and arrow he asked Xie Yannan to make before, and it can easily shoot through tree trunks.

"You let me open up for defense, and then you shoot your bow and arrow at me?"

Xie Yannan understood.He paused for a few seconds, then opened the umbrella.

Although the umbrella is heavy, when it is opened, it can support the entire frame with one hand without any effort.

"Don't be afraid, it's okay, sixteen you also take a bow and arrow."

Wei Beiming not only took one for himself, but also gave Shiliu one and asked him to shoot at Xie Yannan together.

Although Xie Yannan was a little flustered, on the whole, he still trusted Wei Beiming, after all, the whale suit last time was really impeccable.

"I'm fine, you guys move a little faster."

Xie Yannan gently urged a few words, and felt the umbrella shake slightly.

The bow and arrow broke and fell to the ground.

Not only Xie Yannan, even Shiliu was dumbfounded after seeing it. After all, this umbrella looks like a thin layer of white cloth, and it can resist bows and arrows like this.

"This……"

Xie Yannan turned the umbrella over and found that there was no scratch on the umbrella.

"This is a defensive umbrella. Because there are not enough raw materials, the most basic ones are now able to prevent some swords, bows and arrows. I will strengthen my research later, and strive to be able to prevent basic pistol bullets."

Wei Beiming is very sincere and rarely talks. Like Zeng Rui, he concentrates on research and work.

Xie Yannan turned it over to look, only to find that there was a small hole at the top of the umbrella.

There seems to be something vaguely inside the small hole.

"When the umbrella is opened, the top handle is just aimed at the defensive enemy. After the defense, you can continue to press the button on the inner handle. They will release bows and arrows to slander the enemy. Although the attack power is not strong, it is no problem to deal with ordinary people. "

Xie Yannan understands that Wei Beiming is only an expert in disaster prevention, he has more or less experience in defense, and the attack must be relatively weak.

"It's not bad, Uncle Wei is still amazing."

He did not forget to praise Wei Beiming. Although he could only do the most basic defense, for ordinary people, they only had bows, arrows and knives, which could be used for daily defense without any problem.

"They are too old to last. I will upgrade them as soon as possible to make them resistant to bullets, but it is difficult. After all, the density of the thin steel wires embedded in the umbrella leaves is limited. We don't have any other materials, so basically it can't be done."

Wei Beiming explained to Xie Yannan that this requires something very hard to replace the steel wire. The steel wire can play a role in flexibility, and the strong material can play a role in resistance. When the two things are used together, basically the resistance will be better. There is a big improvement.

Hard materials...

In Xie Yannan's understanding, hard materials are nothing more than diamond, which is currently the only thing that can cut glass.

But diamonds can't be found at all now. He has wandered around so many shelters, but he hasn't seen a shelter that supplies such a thing as raw materials.

But he still has a treasure in his hand that can replace diamonds, but he doesn't want to use it casually, that's meteorites.

"This stone, you can see if it's useful."

Xie Yannan carefully took out one, this thing is only one less if you use one, and now the power supply of the entire shelter is all supported by it.

"This stone looks small, but it's very heavy. The density should be extremely high."

Wei Beiming took it, weighed it in his hands, and was full of praise.

"The density must be high. The greater the density per unit volume, the greater the hardness. You can try to see if it can be used. You may not be able to handle this stone in ordinary machines, so it can only be placed in a generator."

Xie Yannan thought that if Wei Beiming wanted to melt it and disperse it on the umbrella, the only way would be through a generator.It was specially processed by Ma Wu, and it was the only thing that could melt the meteorite. It used the meteorite to generate electricity to melt the meteorite, but even if it melted, its energy would not be weakened.
