"What's going on, you're too energetic." Lin Kai pulled He Jun up with a shake of his arm, stretched out his head and looked into the elevator shaft, "What do you say you are doing with this thing?" ”

"Just take a look." He Jun responded casually, picked up the dropped glow stick, and stretched it out into the elevator shaft to look up and down.

The top floor of the elevator here is thick concrete, but there is no mechanical room in sight, and there is no steel cable for pulling the elevator, He Jun only finds a few rows of large racks arranged in parallel on the left and right walls. I don't know how many years of inactivity have been on the rack with rust spots everywhere, just looking at it feels prickly.

It seems that this place is not an ordinary elevator, but a self-propelled elevator that relies on gears to bite the rack up and down.

He Jun found the same rusty iron ladder on the left side of the elevator shaft, but the rust on the iron ladder was obviously much less on the rack, and it seemed to be still usable.

"You don't want to go down here, do you?" Lin Kai's eyes were stunned, and he looked like he had seen a ghost.

"Are you stupid, am I stupid?" He Jun muttered angrily, and as soon as his hand was released, the glow stick fell into the elevator shaft.

He Jun counted to ten seconds, and the glow stick hit the ground, illuminating the two broken door panels.

"Let's go." He Jun turned to leave, and Lin Kai followed depressedly.

He couldn't figure it out, but he was born one hundred and eighty years early, how could the gap with these juniors be so big?

Stopping and stopping all the way, every door that could be opened was opened by the two of them, and He Jun never found any useful clues.

Walk a distance of four or five hundred meters to find an elevator station, and you can find a safe passage between the two elevator stations.

He Jun curiously walked into the safe passage and took a look. I found that the staircase inside was not the kind I usually saw, but a spiral-shaped stone staircase carved directly into the rock wall.

Walked along the corridor for about two kilometers. He Jun suddenly found that the direction indicated by the electronic compass was wrong, and he just entered the corridor. The corridor is north-south, but now it has become northeast and southwest!

Looking back, he realized that the corridor was not a straight line, but a slight arc, which he hadn't noticed before because the arc was too big.

He Jun was stunned for a moment, raised his foot and kicked open a door located in the inner circle of the arc beside him, and rushed in three steps and two steps.

The room was no different from what he had seen before, He Jun groped around on the innermost wall, clenched his fist and tapped it twice. It sounds a bit empty.

He immediately took two steps back, pulled out the laser gun and turned it to sustained low-energy output, and made a hole in the wall.

The cave was pitch black, and a glow stick was thrown into it, immediately illuminating everything in the cave.

Behind the wall was an equally simply decorated bedroom, with three skeletons, one large and one small, lying side by side on a bed that was not spacious.

On the cabinet at the head of the bed, there were some dusty furnishings, and He Jun lifted the picture frame that was buckled on the cabinet. The happy smiling faces of a family of three came into his eyes.

He Jun's breath was suffocated.

Looking at the bed again, the three skeletons are still in the same posture as before, and the arm bones of the two adults are resting on the small skeleton in the middle, as if they are still holding the small body tightly at the moment of dying.

Why did they die?

He Jun leaned over to take a closer look. Before he could get closer, the clothes on the skeleton were shattered.

He said sorry and took a closer look at the three skeletons.

All three skeletons are very intact. The stout skeleton on the left seems to be the hostess, and the slender one on the right may belong to the hostess. There were no defects or fragments, except for an extra knot on the collarbone of the hostess's right shoulder. It may have been a fracture before death.

"See what?" Lin Kai asked curiously.

"No, I don't see anything." He Jun got up helplessly, "I want to see if I can see how they died." ”

The idea was good, but unfortunately he was not a forensic doctor, so he undoubtedly failed.

"Maybe there's one next door." Lin Kai reminded.

"I'll talk about it later!" He Jun saw a window on the wall, and the strange thing was that the glass on the window was actually intact!

He leaned on the glass and looked out, but couldn't see anything.

Picked up the glow stick on the ground and smashed the glass with his hand, and threw the glow stick out of the window with a flick of his arm.

He hadn't expected to find anything by doing so, but he didn't expect the glow stick to fall straight down and hit the ground in ten seconds.

He Jun was taken aback, he never thought that behind the window was actually the vast space under the dome!

Under the dome is a cylindrical space about a kilometer high, if the cylindrical rock wall is covered with such rooms from top to bottom, how large should it be?

He Jun suddenly realized that his thinking had entered a dead end, the space under the dome was definitely more than a small town, counting the buildings built by hollowing out the rock wall, this was a medium-sized city, to say the least!

It's just a small city that has aroused his deep interest, and the small city has become a big city, and He Jun can hardly resist the urge to rush down and take a look immediately.

"Let's go!" He Jun strode away, "Let's go to the next floor." ”

"Done?" Lin Kai asked curiously.

"It's over." He Jun nodded, found the nearest safe exit, and cautiously walked down the stone steps.

He Jun thought that the interval between the two floors was very small, but after actually walking through, he found that the distance between the two floors was not less than ten meters.

Even so, more than 100 floors can be built at a height of more than 1,000 meters, and in order to prevent getting lost, the two of them only walked together close to the cliff, so maybe the depths of the cliff were hollowed out!

After walking four or five floors in a row, all the house structures were exactly the same, He Jun simply stopped looking at it carefully, and only walked out of the stairwell to take a look at each floor, as long as it was the same as above, he immediately turned around and continued to walk down.

After going down ten floors in a row, the two of them encountered a different place on the first floor.

This is no longer a room like a tube building, but a large open space, on which is paved with a layer of dry and hard soil, on which is a layer of yellow and dry plants, and above the head are rows of lamps, many of which have fallen off the rock layer overhead, and fall to the ground horizontally and vertically.

He Jun couldn't believe his eyes, could it be that this was an underground farm?

But there is nothing wrong with thinking about it, the people live in food, and they must first fill their bellies when they live underground, and they must first fill their bellies!

Looking around, there were some small agricultural machinery parked a little farther away, but He Jun couldn't see what they were doing.

The space here is not completely vacant, and at intervals, you can see a particularly thick stone pillar topping between the two floors, with a diameter of less than ten meters, and no less than eight meters.

Needless to say, the stone pillars must have been left behind to reinforce the rock formations. (To be continued.) )
