Doomsday: Unlimited upgrades to the shelter

Chapter 59 Making Explosives From Chemical Fertilizers

When things were like this, Xie Yannan could only bite the bullet and go to the shopping store to see if there was anything that could be exchanged. After all, he only had more than 1000 points in his hand now. It was a bit of a fantasy to exchange for weapons that could deal with those strange things in the sky. .

[System warning: No weapons are provided for now, only weapon synthesis and weapon upgrades are provided]

Fuck!Are you serious? !Xie Yannan became more and more suspicious that this thing was a magic weapon that others deliberately put on him.

Every time the chain is dropped at a critical moment, without exception.

I*****!

Xie Yannan was so angry that he kicked the pillar next to him, this matter was really troublesome, and this group of people still wanted to protect him.

He glanced at Xiaoxiao and Wei Xiaofei who were huddled in the corner. They didn't even look at each other, they just hugged each other tightly.

"Uncle Wei, I have a question for you. I can provide everything except weapons. Is there any way to make something like explosives. The key is to detonate them in the air."

The difficulty is easy to understand, just detonating it in the air is almost impossible, and you have to make explosives with bare hands?Do you use soil from the basement?

But because Uncle Wei is also a weapon expert at any rate, Xie Yannan can only pin his hopes on him at the moment.

What Xie Yannan said, Uncle Wei immediately understood that there is nothing in this basement, it is almost impossible for everyone to deal with the man-eating thing in the sky with bare hands, he squinted his eyes and thought for a while.

"Xiao Nan, can you provide fertilizer? Ammonium bicarbonate fertilizer, that is, the kind with more than 80% ammonium bicarbonate."

That's definitely fine, those are the basics.When Xie Yannan heard what Uncle Wei said, he knew that he was going to make ammonium nitrate explosives.Although Xie Yannan doesn't know the specific ratio, ammonium nitrate can be made from ammonium bicarbonate and nitric acid, which is the simplest and most original explosive.

Although the bomb is basic, its power is not small at all.For example, if it takes 50kg of trinitrotoluene (TNT) explosives to blow up a building, twice as much ammonium nitrate explosives can achieve the same effect.

Xie Yannan quickly searched the system for these two items, "Uncle Wei, I can provide these items."

He thought for a while and then said, "But we still have to ignite it in the air, how about using white phosphorus?"

The ignition point of white phosphorus is extremely low, and it is easy to catch fire at room temperature, which is common sense.This thing can indeed detonate the explosives in the air, but you have to find a way to send it into the sky with the explosives, and then detonate.

In this way, even a group of more than a dozen mutated eagles were wiped out in minutes.

By the way, the white phosphorus can be wrapped in wax to keep the white phosphorus from the air, so that even if the ignition point of the white phosphorus is reached, there is no air to support the combustion.

Because the pills made by the laboratory are covered with a layer of wax, there is still a lot of wax in stock.

After a while, two large lumps of explosives were placed squarely on the ground, and next to them were two white phosphorous wax pellets.

Xie Yannan already had an idea at this moment, tied the white phosphorous wax pellets on the bomb and threw them into the sky, and when he was close to the mutant eagle, he used a bow and crossbow to shoot through the wax on the surface of the white phosphorous.

Although so many are dangerous to a certain extent, but now there are no more points and no more weapons.Xie Yannan secretly made up his mind that he must get an imaginary weapon, at least he couldn't hide in the basement so wretchedly.

Instead, you can hold a rocket launcher and launch it with a swish, killing those monsters in minutes.

"Qin Xiaocheng is with me, you stay where you are."

Due to the problem of the time to throw the explosives, Xie Yannan held Xiaoxiao's close crossbow in his hand, and had to ask other people to help get the explosives.There is only Qin Xiaocheng, a big man here.

"No problem." Qin Xiaocheng's life was originally saved by Xie Yannan, and every day he lives longer counts.

After the two walked out of the basement, they heard rustling in the air.

Qin Xiaocheng had never seen such a scene before, his body visibly shook, and he subconsciously hid behind Xie Yannan.

Because the sky is pitch black, but fortunately the moon still has a little light, and we can vaguely see the shadows hovering in the sky.Like the last time he dealt with the mutated eagle, Xie Yannan sprayed himself and Qin Xiaocheng with 84 disinfectant before leaving the dungeon. In this way, it seemed that the mutated eagle had some scruples about the smell and would not attack suddenly.

Xie Yannan took Xiaoxiao's flashlight, because the sky was too dark, he had to point the flashlight at a point on the ground, so that from the scattered light reflected from the ground, he could see where the mutant eagle was hovering.

[The system has turned on automatic scanning]

[Mutated Eagle: 10]

Sure enough, as Xie Yannan had expected before, the mutated eagle usually would not launch an attack alone, but the two big lumps of explosives he had injured were more than a mistake when dealing with the mutated eagle.

He made a squatting gesture for Qin Xiaocheng, and now he tried to make the least noise, while suddenly stimulating the mutant eagles, causing them to attack suddenly, which would catch Xie Yannan by surprise.

He pointed to the dark ball, and then made an upward throwing motion.

Qin Xiaocheng understood immediately, he grabbed the rope of one of the packs of explosives with his hand, and threw it out with all his might.

The moment the explosives were thrown out, Xie Yannan quickly shot a bow and arrow with a close crossbow.Because the two squatted together, it was relatively easy to determine the location of the white phosphorus. In addition, just to better identify the location of the white phosphorus wax ball, Xie Yannan even applied some fluorescent powder on purpose before leaving the basement.

In other words, the white phosphorus was completely exposed to the air from the moment the explosive was thrown out.The mutated eagle overhead was no more than 2 meters away from them. After these two meters of air friction and heating, it just reached the ignition point of white phosphorus, driving the explosives to explode.

"Go back to the basement." Xie Yannan saw that Bai Phosphorus was shot by the crossbow, and quickly asked Qin Xiaocheng to follow him back to the basement.

The explosives are self-made, and the danger is still low. I don't know how powerful the explosion will be, so we need to find a shelter first.

Although Qin Xiaocheng was a little timid, he didn't run away in the end.Regarding this point, Xie Yannan was still very satisfied, "Thank you for your hard work."

He patted his shoulder.

"It's okay, we were all rescued by you, and our lives are yours. However, there is a saying, I don't know if I should say it or not?" Qin Xiaocheng hesitated, squinting at Xie Yannan.
