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

"boom--!"

He heard the sound of the tunnel entrance being blown up behind him. It was probably Noel who was helping him block the pursuit.

This underground passage stretched in all directions, and there were several forks after a while. He could only try his luck to see if he could encounter the oracle.

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

This corpse had only bones left, and even its clothes had rotted away. It was lying on the ground with its arms on its chest, and its palms were protecting something.

Su Mingan took a look and found that under its palm was a blurred photo.

He continued walking and found many corpses along the way. Each of these corpses held a photo in their 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 circle of light appeared in his field of vision, which was a hint of clue insight.

He immediately speeded up and saw an earth wall in front of him.

He exerted force with his feet and used the skill of the Water Realm Boots to kick forward. The moment he exerted his force, a sound of water flowed across his calf -

"boom--"

The earthen wall shook, but it did not collapse.

He took a step back, feeling a dull pain in his right leg from the rebound force.

After this earth wall...it seems there is a harder wall.

He stretched out his hand, and the amber knife appeared in his hand.

After upgrading his professional skills, he has been able to fully utilize the power of this sword.

"boom--!"

A violent breaking sound sounded.

As he swung the long knife, light patterns like crackling water waves appeared in front of his eyes.

The thick earthen wall was shattered at this moment, shattering like a spider web, revealing a silver-white metal wall behind it.

He swung the knife again, and the effect of space fragmentation was fully displayed. With a sharp "click" sound, he directly cut a hole in the seemingly extremely hard metal wall.

A bright light suddenly shot out from the wall.

...Is there light inside?

He drilled along the hole, and his eyes suddenly brightened up, as if a light had been turned on in a dark world.

He looked at the scene inside with some shock, as if he had seen a world with a suddenly different style of painting.

Directly in front of him is a silver-white metal wall. This wall surrounds the entire room, giving people a strong sense of security. In the wooden railing at the corner of the table, various metals glow with a glassy white light.

.

He turned around, but suddenly bumped into something, making a crisp "ding, dong, dong, dong, dong, dong, dong" sound.

Next to him is a glass cabinet, which contains various bottles and jars with unknown uses. These bottles have been broken and the liquid inside has dried up.

He looked around. Scales, measuring cylinders, test tubes, knives... they were scattered in every corner. A few discarded pieces of paper fell to the ground, and there were no traces of the ink.

He even saw a table of chemical elements hanging on the wall, as well as precision iron instruments. There were some pulled and dried blood stains on the ground, as well as some torn clothes and fabrics. He didn't know what had happened here.

...What exactly is this place?

How could there be such a modern technology-like laboratory in a primitive tribe-like dome?

Judging from the current situation, the people who originally lived inside must have fled in a hurry. Otherwise, the place would not be so chaotic, and it would be similar to the scene after the disaster.

He crossed over the instruments and glass pieces scattered on the ground and walked towards the dusty experimental table.

"Ding dong!"

[Obtain key clues·Underground laboratory]

[(Underground Laboratory): You discovered that there is a modern laboratory hidden in the underground passage of the First Tribe. What does this mean? 】

…

[You found (No. 100 metal), (broken chemicals), (destroyed iron instruments), (messy formula paper), do you want to conduct an investigation? 】

"Investigation." Su Mingan said.

…

[You lack relevant experimental knowledge and scientific research level, so you cannot investigate.]

…

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

However, this is reasonable. After all, his knowledge of chemistry and biology is only at a high school level and he cannot understand these messy formulas. Moreover, there are many special letters and symbols in them that are not found in his original world.

In the whole room, the only thing he could understand... was probably the periodic table of elements on the wall.

Also limited to the first twenty elements.

He took back his hand and dusted himself off.

The laboratory is not small. In addition to this room, there are several experimental rooms with various instruments, as well as several large iron cages stained with blood. The iron cages are empty, and it is unknown what was contained inside.

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

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

If the place just now was the experimental area, this should be the living area. Sofas, soft chairs, wardrobes, rotten fruits in the cabinets, coats hanging on hangers, and aged razors with beards... all showed that,

This is a place to live.

The people in this room also seemed to have left suddenly, leaving only various daily necessities behind.

"Is anyone there?" He called out, but no one responded.

He continued to enter and suddenly found a photo hanging on the wall above the sofa.

However, what is very strange is that this is obviously a very vast photo wall, but only three or four photos are hung here and there. Hundreds of nails without photos are stuck in the wall, leaving a large area vacant.

.

He immediately stepped onto the sofa, intending to observe these photos.

"Bang! Bang!"

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

The sofa was quite old, and the leather was all pitted and tattered, as if it had been chewed by someone. There was only a thin layer of cloth left on the surface, and it tore after he stepped on it twice.

Speechlessly, he pulled out his leg and looked at the photos directly with his shadow-like eyesight.

These photos include individual photos and group photos. The people are wearing modern clothes, and the backgrounds behind them are different.

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

This is a photo of a family of three.

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

Both of them have oriental faces with soft lines, black hair and black eyes. At this time, their faces are full of smiles, as if they are looking forward to a better future.

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

…That’s a blue ocean.

Under the sunlight, the blue sea looks even more sparkling. It blends with the reef-like island in the distance, beautiful and full of life, like a quiet sunset oil painting.

What the man in the white coat wears on his chest is a gorgeous rose. It is dotted on his white coat like a ruby, like a shining piece of blood.

Su Mingan remembered... there is no sea in the sky, and besides the miraculous Cursed Fire Flower, there are no other flowers that can bloom in the sky.

Previously, there was a bright red Cursed Fire Flower in Sibor's hair. She said that due to the heavy pollution, it was difficult for other flowers to bloom except the Cursed Fire Flower.

Things that are not found in both types of dome appear together in this photo, which is enough to explain a lot.

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

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

There is no way in or out of the dome. Did they... take the initiative to cross that black wall and come to the dome?

Su Mingan looked away and continued walking inside, seeing rows of beds with messy sheets.

He searched the beds and suddenly found a large cardboard box hidden under the bed. There were piles of letters in the cardboard box. They were carefully glued into a small book and could be opened page by page.

He turned over a page, and a puff of dust hit his face.
