Doomsday: Unlimited upgrades to the shelter

Chapter 151 Assault on the Refuge
Next to the stacked plastic is a large balance scale, which automatically weighs things with an accuracy of 0.01 grams.

The flat tray is huge, about two meters long and wide.

Xie Yannan wondered whether the plastic still needs to be weighed. When he suddenly looked up, he found that the trading rules seemed to be engraved on the wall.

[Mall transaction rules; 1. This mall is an automated mall, and the demand is food;

2. The types of grain required include wheat, rice, sorghum, etc., which are traded according to the principle of equal weight;

3. After weighing the grain on the balance scale, the system will record the data independently.Then put the required goods on the other end and weigh them, and you can take away goods of the same weight.

If you take too much, the laser light will automatically activate the protection mechanism, causing injuries to traders.

4. Please trade cautiously according to the rules. I wish you a happy transaction. 】

That's it!

Although it is a second-level refuge, it adopts an automated trading model, which seems to be much ahead of the previous doomsday malls.

Xie Yannan paused, before going out in the system, he only stored the anti-epidemic pills in it.

This time, it seems that he can only figure out the rules first, and then go back and prepare the materials for exchange, making a good plan.

With the current transaction design, it is impossible to forcibly take away these raw materials. The level of laser light alone is beyond the reach of ordinary people. It is not known whether there are other emergency measures in this shelter.

He could try to forcefully take things away, fearing that he would accidentally trigger the shelter's self-destruct device, and everything would be in vain.

Xie Yannan thought for a moment, then Bian and Xiaoxiao went to another house, this house was full of pieces of glass products, it should be used for glass trading.

Calculating casually, this thing is not very cost-effective to exchange. The same weight of food can only be exchanged for the same weight of glass, and the glass is more than ten times more expensive than usual.

But each shelter has its own needs. For example, in the previous shelter, their needs were pills, and in this shelter, their needs were food, which should be determined by the builder.

There is still a circle of laser light around the glass, and ordinary people's hands can't reach it at all.

"Xiaoxiao, let's go back first, go back and prepare some food."

Xie Yannan didn't want to spend too much time here, now that he has figured out the rules, he will wait until he goes back to make a good plan.

There is still a lot of food in the storage room. I took all the things that have been out for a long time and returned them in exchange for raw materials for upgrading the bedroom.

When checking the map, Xie Yannan had already discovered that this place was not far from the apple orchard.

It was the location where Xie Yannan harvested the biochemical apples yesterday, and he planned to drop by to harvest some more apples, maybe he could even design and make his own powerful weapon.

Xie Yannan and Xiaoxiao went there only to find that the large apple orchard had disappeared strangely, even the trees and the broken bones on the soles of their feet were gone.Only normal black and brown land and lawn remained.

But there are traces of being crushed on the lawn, which is obvious.

Xie Yannan frowned, some things happened so strangely and miraculously.It was too late for him to react.

Who would let these apples, which looked like biological weapons, disappear silently overnight, Xie Yannan couldn't imagine.

But there was nothing there, and there seemed to be no traces left on the ground that could be traced.

This trip didn't seem to yield anything, so he and Xiaoxiao drove the octopus back in a somewhat despondent manner.

As soon as I walked not far from the basin valley, I heard a very crisp bang bang bang sound, as if something fell on the glass and was bounced back.

He couldn't help being a little worried about Wei Xiaofei who was in the refuge, and quickly ordered Xiaoxiao to speed up the driving speed of the octopus.

Sure enough, when Bungu appeared in Xie Yannan's field of vision, there seemed to be something dancing on the wall above his head, and some dazzling sparks popped out from time to time.

Fuck!What the hell is this.

Xie Yannan was startled, and immediately realized that the shelter had been attacked.

He opened the door and rushed inside desperately.

Just above his head, the two defense lines of "sugar cube" and laser tunnel were originally fortified, as if they were suddenly pulled open a big hole.

There are clusters of fire-like objects that are constantly hitting, but they are basically reflected or burned by the defense line. Only the burning stars can break into the valley, although they can't pose any real threat. But it still made Xie Yannan feel scared.

Xie Yannan was wondering what these things were, looked around and there was no one around, everyone should have taken refuge in the basement.

He hurried to the basement, and sure enough everyone was gathered together, "What the hell are these things outside, and how long have they been going on?"

Xie Yannan opened the door and asked three times.

Although they are currently blocked by the defense, they basically pose no threat to Pengu.

But their continuous impact will cause the defense of the basin to collapse completely.

"We didn't know it, we were outside, and suddenly there was a sound like an airplane in our ears, and then there were these little things hitting the ceiling."

Qin Xiaocheng said truthfully, there was obviously a little more worry in his words.

"Uncle Ma, do you know what this is?"

Xie Yannan turned his head to face Ma Wu who had been sitting on the ground with his chin resting on his back. His expression was a little serious, without a glance, as if he was thinking about something.

"I don't know, but we can understand it as a high-tech weapon."

Uncle Ma sighed, saying that he was not omnipotent, and it was the first time he had seen such an attack weapon.

"So what can we do?"

Are you hiding here?Helpless?Wouldn't he be caught by the enemy?

Xie Yannan continued to question Ma Wu.

Ma Wu shook his head, "Bengu's built-in defense is now fully capable of resisting, it's just a matter of time. The first wave is the strongest, after the first wave, there are only minor problems."

These words are equivalent to comforting Xie Yannan.

Everyone looked at each other in blank dismay, not knowing what it was.

However, now that Ma Wu has spoken, it means that this thing does not pose any threat to them. Once this wave of attacks is over, everything in Pengu will return to normal.

"But...but I found a very strange scene."

Ma Wu took out a mini tablet from his backpack.A few lines were drawn crookedly on the black screen.

"This is an electromagnetic wave. According to reason, there should be no pulse type here. Since the outbreak of zombies, all communication equipment has been cut off. How can this happen?"
