My Doomsday Shelter Unlimited Upgrades

With a glance, Jiang Yanbing understood what was going on.

Without any words, Jiang Yanbing took out a small hammer from his backpack and began to knock on the rocks on the wall.

"You still carry this thing with you?"

Chen Yang stared wide-eyed. He did have a shovel in the system backpack, but he didn't take it out.

"That's right, you didn't flip through my backpack, it's a common thing for survival in the wild."

"Here." Jiang Yanbing handed the hammer to Chen Yang:

"You use this."

Chen Yang shook his head: "I just use stones, the efficiency is faster than yours."

It's not that Chen Yang is blind, stones with different edges and corners are sometimes easier to use than this hammer.

The force area is small, the pressure gun is large, simple physics knowledge.

Jiang Yanbing snorted twice: "Then let's compare?"

Chen Yang smiled: "Okay, so why don't you add some color?"

Jiang Yanbing is also quite confident:

"Add it, add it, if I win, you will delete all those photos you secretly sent."

Chen Yang raised his eyebrows: "Then what if I win?"

After a brief acquaintance, Jiang Yanbing under the mask gritted his teeth: "If you win, I'll show you something you haven't seen before."

"A word is settled!"

Chapter 166 Non-Newtonian Fluid + Memory Metal = Unknown Gate

The result of the match, of course, was Chen Yang's victory, which he was sure of for a long time.

What is treacherous and cunning, what is knowledge is power!

The previous rule was that two people were in charge of two corners respectively, and neither of them could see their progress.

Jiang Yanbing, who was just knocking bit by bit, thought that his speed was already super fast. How could Chen Yang have used his knowledge of physics.

Break the surface with points and make a few reference points on the wall. Following these points, you can peel off a large amount of rock skin attached to the outside like poking the skin of an egg.

It can be said that before Jiang Yanbing's side started, Chen Yang's side had already ended.

Jiang Yanbing stared far away, no matter how hard she thought about it, she couldn't figure out how she lost, since she still had modern tools.

It wasn't until Chen Yang demonstrated the process to her that Jiang Yanbing realized that she had been fooled.

I knew I had no good intentions... Thinking of the previous bet, Jiang Yanbing blushed pretty.

However, Chen Yang didn't intend to delve into it for the time being. The metal skin after removing the rock wall skin exceeded his expectations again.

According to his previous thinking, he thought it was a shell made of metal, but it was only coated with a layer of rock coat.

But now Chen Yang discovered that things were not that simple. There was a concave groove on the metal surface, like a door handle.

Another door? ...While Jiang Yanbing, who had obtained the method, was cleaning up the rock coating on a large scale, Chen Yang walked to the other side of the room, trying to cut through the wall.

With just a chisel, Chen Yang felt the difference.

The wall at the back is a rock wall that was plated later, and the thickness of the rock layer is only a dozen centimeters, but the rock is rock after all, and it is incompatible with metal, and the rock layer will crack and fall off when it is knocked.

But the wall on this side, after being chiseled, only has a solid feeling.

There are no cracks, only small pits at most. Because there is no power to buffer, most of the reaction force is fed back to the stones used to strike, and even caused damage to the tools used to chisel the wall.

This confirmed Chen Yang's conjecture just now.

It's not a metal house, just a hidden metal door over there.

What does the hidden door represent?

It means there is a baby!

Chen Yang returned to Jiang Yanbing's side, and also began to plan the wall hard.

The size of this door is also not small, with a width and height of two or three meters.

When the whole door appeared, Chen Yang was surprised to find that there was nothing else in the whole door except the doorknob.

How to open the door?

Jiang Yanbing forgot to glance at Chen Yang.

Chen Yang nodded: "You hide aside first, I'll see if I can open it."

After Jiang Yanbing started to face the wall and think about his mistakes, Chen Yang took out his AK47, ready to test the depth of this door first.

'Da da da! '

Jiang Yanbing was taken aback by Chen Yang's sudden shooting.

But after a shuttle shot down, Chen Yang was even more startled than Jiang Yanbing.

The bullet hit the metal gate, effective, but not completely effective.

The very strong metal gate itself was like a sponge at this moment, it first sucked the bullet firmly, and then fully rebounded to 'spit' out the bullet embedded in it.

Memory Metal!

Non-Newtonian fluid!

These two words popped up in Chen Yang's mind immediately.

This door is like a combination of the two. It may feel fine at ordinary times, but once it encounters this brute force method, it will become extremely resilient.

Chen Yang was stunned for a moment, he had never heard of such a thing in modern times.

Memory metals are generally used in space, as antennas or radars or satellites.

The size of these things is too large, it is too inconvenient to carry directly, and of course it cannot be wrapped around the waist.

At this time, memory metal comes in handy.

First make the original shape, then use a special method to press it into a ball, and then vacuum pack it.
