My Doomsday Shelter Unlimited Upgrades

Chen Yang continued to study the murals on the door, and Jiang Yanbing also leaned over, trying to find some other clues.

"Do you know the above?" Chen Yang asked.

Jiang Yanbing was staring at the strange symbols on the door and shook his head:

"never seen it."

Chen Yang snorted twice, and made a few jokes casually:

"I thought our Senior Colonel Jiang knew everything, but there are things we don't know."

Jiang Yanbing turned his head and gave Chen Yang a white look with a resentful look.

"Who told you I know everything?"

Chen Yang chuckled: "Guess."

After finishing speaking, Chen Yang's expression became serious again: "Did you find anything?"

Jiang Yanbing frowned, pointed to a place in front of him, and said:

"I don't know if this counts as a discovery... You can take a look."

Chen Yang stood up, and Jiang Yanbing made way for Chen Yang to see the pattern on the door more intuitively.

The location Jiang Yanbing pointed to is also a mural composed of patterns and pictographs, but it is somewhat different from the door on the left, which is obviously mostly patterns.

It's like reading comics. Although you can't read the text, you can enjoy the pictures if you can understand the patterns.

There is also relatively little dust in this area. Chen Yang simply blew it twice, and a large area came into view.

In the painting, it can be seen that people wearing primitive ornaments and holding spears, and there are a large number of people, are surrounding a particularly high gate.

There is no pattern on the gate, but judging from its shape and proportion, Chen Yang can bet that the door on the mural is the one in front of him.

"So there was this place first, and then the paintings on the door..."

Chen Yang's brows gradually began to knit together.

This is already a shocking discovery.

Now at least one problem can be explained, at least someone has been to this place before.

It may have been thousands of years ago, or it may have been earlier, but judging from the patterns and styles on the murals, it is definitely too late.

In what era do people still not understand how to wear clothes?Chen Yang is not proficient in history, but it should be a long time ago.

But what shocked Chen Yang the most was that this door was earlier than the appearance of these ancient civilizations!

Chen Yang dared to bet that things like 'stairs' would never have appeared in the era reflected in the murals.

He can understand this door.

Egypt has the pyramids, and China has the Great Wall, both of which are miracles in human history.

Even thousands of years ago, if someone deliberately built such a gate here, with a large space inside, it would not be impossible.

After all, in human history, most of them have regarded this kind of magnificence as their beauty.

The key is whether the stairs above were also built together with the gate, or were they built by later generations.

If it was built by later generations, it can also be explained.

But if it's built together...it's a bit of a slog.

Chen Yang took a quick look at the surrounding murals, but unfortunately, apart from the gate, there was no depiction of the external environment at all.

Chen Yang and Jiang Yanbing looked at each other, and seeing Chen Yang's serious expression, Jiang Yanbing, who thought it was nothing at first, swallowed involuntarily.

"Could it be..." Jiang Yanbing said.

Chen Yang shook his head:

"It shouldn't be an ancient mausoleum...Although I don't have any evidence, who's tomb would build such a gate?"

"..."

Seeing that Jiang Yanbing didn't speak, Chen Yang was a little puzzled.

"what happened?"

"That's not what I said."

"what is that?"

Jiang Yanbing took a deep breath and adjusted his state:

"You said it's impossible to be the remains of aliens?"

Chen Yang's hand that was gently wiping the dust on the door suddenly froze, and he couldn't help turning his head to look at Jiang Yanbing.

Jiang Yanbing looked serious, and Chen Yang didn't think it was funny.

It's really possible!

Just like what Jiang Yanbing said before, even the end of the world has happened, so what is impossible?

But Chen Yang turned his head and began to think seriously, what are the aliens doing in this secret base?

And even if aliens come, shouldn't they use some alien materials, no matter how bad it is, they have to use some metals from the blue star to build houses, right?

Although the gate made of rock is also very strong, it is definitely not as good as modern alloys, let alone the high-strength metals that aliens may have.

Seeing that Chen Yang was lost in thought, Jiang Yanbing casually added:

"I guessed it too, don't think about it."

Chen Yang nodded: "I know."

Abandoning these wild thoughts, Chen Yang began to look down.

Now he has found a little pattern. Although he still can't understand the meaning of pictographs, Chen Yang has become more and more aware of pictures.

The mural on the wall is like a diary, and it should record the process of this group of people opening the door.

Jiang Yanbing didn't check the follow-up carefully just now, Chen Yang greeted, and both of them squatted on the ground, and began to interpret the information above.

The picture I saw just now should be the group of primitive people discovering this gate.
