Nine small gates and one main gate were all completely damaged.

These nine small doors are connected to a room that is exactly the same as when Xia Yanzhen was awake.

It was also shattered, leaving only ruins and remains.

The wreckage was not just the remains of buildings, but also the remains of people.

Xia Yanzhen saw bones and mummies.

He walked out of the broken door and faced a steel wall, four meters high, with something similar to a cannon mounted on it.

There are ten doors in total.

Can be moved via rails on the wall.

Today, only one door remains intact.

Of the remaining nine doors, three were completely destroyed, and six seemed to be still usable after repair.

But the steel wall itself is also close to being scrapped.

The steel wall was one meter thick, but it still could not block the intruder's attack.

There are seven or eight large holes up to three meters high, and there is even a crack that completely tears the wall apart.

The entire wall presents an arc shape and is connected to the mountain wall behind.

Surround the area to form a camp.

Unfortunately, it was eventually breached by an unknown enemy.

Outside the semi-transparent room, Xia Yanzhen also saw two anti-aircraft guns.

One of the doors was damaged, but the other door was intact.

"There are only two anti-aircraft guns, and I haven't seen any operation. Will they automatically track the enemy?" Xia Yanzhen walked over and studied them for a while.

It was discovered that there were many red traces on the wreckage of the pair of air cannons.

A slightly pungent smell, unknown liquid, paint or blood?

Including ground cannons and damaged steel walls, there are such solidified red traces.

Xia Yanzhen turned around and looked at the mountain wall behind him, where there was a dark cave entrance.

Three meters high and five meters wide.

This is the mine.

As expected, he will drive a mining machine into the mine to look for ancient relics.

So, the question is, what about the mining machine?

The entire camp was in a mess, with various wreckage and ruins, and only a few defensive guns were intact.

There is not a single mining machine in sight.

Could it be that someone took it away?

When you are a gold miner, you cannot dig with your bare hands!

After taking a look at the black mine without any light, Xia Yanzhen returned to the room and took out his helmet - without putting it on.

There are lights on the helmet.

Turning on the light, Xia Yanzhen walked into the mine holding his helmet, using it as a flashlight.

After passing the ten-meter-long passage, the interior of the mine suddenly became much clearer.

A hemispherical space with a diameter of about thirty meters.

"Fortunately, here."

Xia Yanzhen saw several "mining machines" parked here.

The mining machine is not the shape of a car or excavator as you imagined, but it looks very strange.

How do you say it? A long worm made up of several spheres?

Xia Yanzhen glanced behind him. In the camp outside, there were also the remains of the hemisphere. It turned out to be the remains of the mining machine.

There are only two mining machines in the mine hall.

One is composed of five "balls", and the other is mostly broken.

Walking to the intact mining machine, Xia Yanzhen raised his head and took a look.

The sphere that makes up the mining machine is three meters in diameter and as high as the mine gate.

The one at the front is the cockpit.

There are two layers of "balls" inside and outside. The inner "ball" is made of transparent "glass", and the outside is made of a large number of hollow metal balls.

The sphere at the back is completely black.

Just from the appearance, it looks more like an amusement park facility than a mining tool.
