Su Mingan ran down the stone steps and his watch lit up.

"boom--!"

He heard the sound of the tunnel entrance behind him being blown up. It should be that Noel was helping him stop the pursuit.

This underground passage is well-connected, and within a short while there were several forks. He could only try his luck to see if he could encounter the oracle.

As he walked a corner, he saw a body lying in the dirt.

The corpse was left with only bones. It was lying on the ground, with its arms on its front chest, and its palms protected something.

Su Mingan glanced at it and found that there was a blurred photo under its palm.

He continued walking and found many corpses along the way, holding a photo in his arms.

...Why did these people die here? Why are they still holding photos in their hands?

Su Mingan was a little confused.

He continued walking for a long time.

Finally, a bright red aperture appeared in his field of vision, which was a clue to the clues and insights.

He immediately accelerated, and there was a wall of earth in front of him.

He exerted force under his feet, and used the skill of the water boots to kick forward.

"boom--"

The earthen wall trembled, but it did not collapse.

He took a step back, and his right leg was bounced with a recoil force.

Behind this earthen wall... there is a harder wall.

He reached out and the Amber Sword appeared in his hand.

"boom--!"

A violent sound of breaking sounded.

With the blow of the long sword, cracked light patterns appeared in front of his eyes.

The thick earth wall was broken apart and broke into a spider web-like shape, revealing a silver-white metal wall behind it.

He swung his knife again, and the effect of space shattering was fully displayed. With a sharp sound of "crack", the seemingly extremely hard metal wall was directly cut by him.

A bright light suddenly shot out from the wall.

...Is there light inside?

He drilled into the hole, and suddenly his eyes were bright, as if the dark world had been turned on.

He looked at the scene inside in shock, as if he had seen a world with a sudden different style.

In front of him was a silver-white metal wall, which surrounded the entire room. In the wooden railing at the corner of the table, various metals were shining with a layer of glass white light.

Next to him was a glass cabinet, with bottles and jars of unknown purpose placed in them. The bottles were broken and the liquid inside had dried up.

He patrols around, balances, measuring cylinders, test tubes, knives... They are scattered in every corner.

He even saw the chemical element table hanging on the wall, as well as precision iron instruments. There were some pulling, dry blood, and some broken clothes and cloth on the ground, and I wonder what had happened here.

...What exactly is this?

In the primitive tribe-like dome, there is such a modern technology-like laboratory?

Judging from the current situation, the people who lived there should have escaped in a hurry. Otherwise, it would not be so chaotic here, which would be similar to the scene after the disaster.

"Ding Dong!"

【Get Key Clues·Underground Laboratory】

[(Underground Laboratory): You found that the underground passage of the First Tribe was hidden in a modern laboratory. What does this mean?]

...

[You have found (100 metal), (fragmented chemicals), (destroyed iron instruments), (messy formula paper), and have you investigated?]

"Investigation." Su Mingan said.

...

[You lack relevant experimental knowledge and scientific research level and cannot detect it.]

...

Su Mingan didn't expect to get such a prompt.

But this is reasonable. After all, his knowledge of chemistry and biology is only at high school, so he can't understand these very messy formulas.

The only thing he could understand in the entire room... was probably the periodic table of elements on the wall.

It is also limited to the first twenty elements.

He withdrew his hand and slapped the dust on his body.

The laboratory is not small. In addition to this room, there are several laboratory rooms with various instruments, as well as several large iron cages stained with blood. The iron cages are empty, and I don’t know what was locked inside.

After walking around, he saw an iron door in the corner.

He slashed open with a knife, revealing the scene in the room.

If the place just now was the experimental area, it should be the living area. The sofa, soft chair, wardrobe, rotten fruit in the cabinet, the coat hanging on the hanger, the aging razor with the remaining beard... all show that this is a place to live.

The people in this room seemed to have suddenly left, leaving only all kinds of daily necessities before leaving.

"Is anyone?" he spoke, no one responded.

He continued to enter and found photos hanging on the wall above the sofa.

However, it is strange that this photo wall is obviously a very wide, but only three or four photos are hung scattered. Hundreds of nails without photos are stuck in the wall, leaving a large area empty.

He immediately stepped on the sofa and planned to observe the photos.

"Bang!Bang!"

With two crisp sounds, he felt his feet empty and his legs pierced directly into the sponge of the sofa.

This sofa has been a bit old, and the leather is bumpy and rotten like someone has chewed. There is only a thin layer of cloth left on the surface. It will be broken after he stepped on it twice.

He pulled out his legs speechlessly and directly observed the photos with his own vision.

These photos include single photos and group photos. People are wearing modern clothes.

He observed, his eyes paused in front of a photo.

This is a photo of a family of three.

The man in the photo is wearing a white coat and a card-like card hanging on his chest, while a woman in a normal long skirt is next to him, holding a baby in her arms.

Both of them are Eastern Holes with soft lines, and their faces are full of smiles at this time, as if they are looking forward to a bright future.

The reason why Su Mingan's eyes stopped was because of the background behind them.

...It was a blue ocean.

Under the sunshine, the blue sea looks even more shimmering. It blends with the reef-like island in the distance, beautiful and lifelike, like a quiet and beautiful painting of the sunset.

The man wearing a bright rose on his chest was a ruby ​​dotted on his white coat like a shining blood on his mouth.

Su Mingan remembers... there is no sea in the dome, and in the dome, there are no other flowers that can bloom except for the miraculous flower of curse fire.

Previously, there was a bright red flower of curse on Xiboer's hair. She said that due to the heavy pollution, it was difficult for other flowers to bloom except for the flower of curse.

The two kinds of things that were not in the dome appeared on this photo together, which is enough to show a lot.

These photos should be photos of the experimenter who once lived here.

The period when these photos were taken should be before these experimenters entered the dome.

There are in and out of the dome. Did they... take the initiative to pass through the black wall and come to the dome?

Su Mingan withdrew his gaze and continued walking in, seeing rows of messy beds.

He searched the beds and suddenly found a large carton hidden under the bed. There were mountains of letters piled up in the cartons. They were carefully glued into small books and could be opened page by page.

He turned a page and a gas of dust rushed towards him.

...

【Pingping:

Exhibition of Xinjiao.

It has been dozens of days since I arrived at the dome with my colleagues.

It really takes courage to cross the black wall, but my memory has recovered under the stimulation of photos and books, and I remembered you again. Before this, I was so confused that I was really funny, but fortunately I didn’t let you and my daughter see it.

The colleagues of the engineering team have begun to build underground laboratories. We are temporarily living in confined buildings on the ground. The waiting time is a bit painful. The black fog at night is indeed as terrifying as rumors.

But it doesn't matter, I'm starting to write to you, I'll spend this difficult time.

Although these letters cannot be delivered to you, I imagine you will see them, and let them be used as self-entertainment first.]
