My Doomsday Shelter Unlimited Upgrades

At least that's what it looks like on the surface.

Whether there is any specific danger, Chen Yang has not yet seen it, but he already feels a lot more relaxed in his heart.

Ten minutes later, the heavy door was completely opened, revealing the contents inside.

And as the door was opened, the master key that had been embedded in the door was returned to the system backpack again.

Only then did Chen Yang notice that the door was made of mortise and tenon structure.

This is a very traditional but very useful structural method, which is mainly a connection method that uses the combination of concave and convex parts of two different parts.

The convex place is naturally the gate, and the concave place is the ground.

This kind of craftsmanship is almost forgotten now, and because of this, many people on the Internet are calling for the protection of cultural heritage, which is how he learned about it.

This is the wisdom of the Huaxia people, but it made Chen Yang even more confused.

Judging from the time point of the previous calculation, there should be no mortise and tenon joints, right?

Did this thing exist many, many years ago?

Chen Yang scratched his head, unable to find his way of thinking for a while.

But one thing is certain now, the mural on the door was definitely not drawn by any artist casually, and the authenticity should be guaranteed to a certain extent.

The biggest feature of the mortise and tenon structure is its firmness. Coupled with the thick and strong rock gate itself, it is basically impossible to open the gate with brute force, and a specific unlocking method must be used.

It would be difficult for those primitive people to open such a door thousands of years ago.

"The door is open, come out, there should be no danger."

Chen Yang yelled, and Jiang Yanbing, who heard the voice, quickly moved out from the other side of the stairs.

The moment Jiang Yanbing saw the scene behind the door, Jiang Yanbing's mood was not much different from Chen Yang's.

Speechless.

There is simply an endless feeling.

Chen Yang didn't bother to assign any more tasks. If the sheriff was allowed to go down again, he would have to wait another ten minutes for the skill cooldown time alone.

If this continues, the patience for fighting will be exhausted by himself.

Chen Yang took out the AK47 behind him, loaded the bullets, and after confirming that there was no problem with the lighting, he said:

"Let's go, let's go down together to see the situation, the black meteor that the sheriff needs may be down there."

Just as Jiang Yanbing was about to speak, the police chief jumped out of her arms while she was not paying attention, and was about to run forward.

Fortunately, Chen Yang had quick eyesight and quick hands, and brought the sheriff back, but at this moment, Chen Yang was secretly happy.

Really in stock!

Perhaps the meteorite for the evolution of the violent bat came from here, and for some reason, the meteorite came outside the door.

"and many more..."

Thinking of this, Chen Yang felt that he had discovered another blind spot.

The meteorite fell down more than a year ago, and this door has not been opened for a long time, how could the black meteor go inside...

Chen Yang let out a big breath.

Although the analysis before the battle was beneficial to the subsequent actions, he couldn't figure out why now.

If you continue to think about it indiscriminately, I am afraid that your brain will crash.

Just go down and have a look.

Chen Yang put the sheriff back on the ground:

"You can take the first one later, but don't run around."

Before letting go, Chen Yang seemed to have thought of something, and added another sentence:

"Running around and having nothing to eat tomorrow."

It was only then that Chen Yang let go of his hand, and the sheriff who fell to the ground did not run around, but kept bouncing back and forth in place, appearing very active.

But when Chen Yang was about to enter the gate, Jiang Yanbing suddenly grabbed his hand.

Chapter 162 Luminous stones everywhere, what's the matter?

"what happened?"

"Just go down so suddenly, what if the door is closed?"

Chen Yang froze for a moment.

As soon as I entered the room, the door at the back was automatically closed, and I was trapped to death when I couldn't get out.

This seems to be common sense.

But, not here with him.

Chen Yang smiled: "If you close it, open it again."

Jiang Yanbing was also a little dazed for a moment.

This door...is it so easy to open?

But seeing Chen Yang's full confidence, her last worry disappeared.

The two and the cat stepped into the back of the door almost at the same time.

Fortunately, the death-defying plot in the movie did not happen, the door was just the door, and it remained there motionless.

Chen Yang breathed out, and started to explore with the bouncing steps of the sheriff.

There is still a considerable distance to the stairs below, and the stairs are still descending in a spiral, with no end in sight.

Along the way, Chen Yang still cheered up, the police chief did not detect any danger, and the overall descent process was much smoother than outside.

Chen Yang gradually quickened his pace, and after 5 minutes, he finally noticed something abnormal.

At the next corner of the stairs, there is a light coming!

At first, Chen Yang thought it was the reflection of the light from his miner's cap on the smooth rock, but when he turned off the light on the cap, Chen Yang found that things were not that simple.
