Are all those missing humans hiding here?

But as soon as this thought came to mind, Gu Xingmiao immediately rejected it.

Even if they lived underground, there wouldn't be enough space for humans to survive on such a large scale.

The teammates were so mysterious that Gu Xingmiao always felt that there must be more to it than just that.

Besides being pitch black, there was even a slight damp smell coming from inside, which suggested there must be water resources inside.

This looks like a natural cave, and there are even many stalactites inside that have been formed over thousands or even tens of thousands of years. The closer you get inside, the more you can hear the sound of dripping water.

Compared to the silence in the entire city, this place is the only place with sound.

But after walking nearly 500 meters into the dark cave——

Gu Xingmiao finally discovered traces of human activity.

The stones inside seemed to be artificially carved, and there were even steps for a person to walk on. At the back, there was what should be high-tech electronic equipment from some secret research institute.

"...Could this be a research institute that our ancestors once had?" Gu Xingmiao said silently.

She said this not only to the people around her, but also to the people in the barrage.

Everyone in the special research institute looked at each other in confusion.

Huh? Do they have such a plan? Have they considered setting up a research institute in a natural cave? I don't think so.

But when I went forward I was blocked and couldn't move forward any further. It seemed that I had to break through the obstacle in front of me.

"It seems that we need a password at this step, but the password doesn't seem to be a difficult problem. It's just that we can't understand it--" 01 paused, with a half-smile on his face.

Gu Xingmiao looked in the direction she pointed and found that it was a silver door that looked extremely burglar-proof and was made of some unknown steel material.

"Then why did you originally say that you didn't need to come back?" Gu Xingmiao quickly realized the contradiction between the two.

If they wanted to see if they could know the password to the door, they should have told me about it quickly when they found me; but their first reaction at that time was to just tell me about it, but not to come to the place.

So now they brought me here again. What changed their minds?

"I feel like these teammates aren't very reliable either. They clearly only turn to the streamer after running into trouble and realizing they can't solve it... They're just using our streamer as a cheat."

"That doesn't mean these teammates are bad. Gu Xingmiao drove for such a long time before, and these teammates let her rest in the car and didn't let her continue exploring. Why do you always think so badly of people?"

"But this cave doesn't look like a human remains that could have housed the entire population of Chang'an, does it? It's just pitch black and a bit scary."

"Because we are worried that the answers we get after entering may not be what we want, so we thought of just forgetting it." Luosangyu said suddenly, as if he had guessed what Gu Xingmiao was thinking.

"But then we thought, we've already come this far, so what's there to be afraid of? We should just move forward fearlessly—"

As she spoke, Luosang Yu's eyes became brighter and brighter: "Although some of us have more or less knowledge of ancient culture, I know that your understanding of ancient culture is different from ours -"

And what she didn't say out loud, Gu Xingmiao understood to an extent that was almost a dimension higher than theirs.

If Gu Xingmiao knew that the person in front of him had such a high opinion of him, he would probably remain silent.

Knowing so much about culture and having so many memories is just standing on the shoulders of giants. It has nothing to do with her own excellence.

The whole of China is excellent.

Gu Xingmiao himself is a person who is willing to explore, not to mention that he knows that many Chinese people can see the future through the so-called live broadcast.

She thought, even if he thought he was just a small person and didn't believe he could change the whole world in the past -

However, the opportunity to explore in the dungeon is like pointing a clear path to the past.

At least we can use past experiences of failure or success to tell people in the 22nd century whether they have better options or paths with a higher probability of success.

"Liu Jianguo: Comrade Gu Xingmiao, if you enter here, it will endanger your life and health. I do not recommend you enter."

"Although past expeditions can teach us many lessons, your safety is equally important. Even though it's been a thousand years, you are still Chinese citizens, and your safety still comes first."

"We should have been the ones charging in the front, but we had to rely on a young boy like you to lead the charge. This already makes us feel extremely guilty and apologetic."

The people above in China do not recommend Gu Xingmiao to enter this cave.

They couldn't judge the danger inside.

I was also worried that they from another parallel universe had set up some danger in the cave, such as a weapon that would cause the entire world to disappear.

In the 22nd century, nuclear weapons have become a common phenomenon that every country possesses. It is not impossible to speculate that some countries will choose to disappear along with all mankind and detonate nuclear weapons when they cannot survive.

Although, the probability of this sounds small.

"Don't worry about me. I didn't sense any particularly dangerous aura. I think it might not be as I suspected."

Gu Xingmiao's voice was a little cold, and when she replied, a large screen barrage of comments appeared above her head.

It’s like the copywriting on the heads of cartoonists in the comic world.

Especially when Gu Xingmiao walked to the edge of the door and found the Chinese national flag engraved on it with a special relief technique——

What's more, under the national flag, there are some words buried in the dust.

Gu Xingmiao raised his hand and wiped away the dust with his fingertips, and he found that it was not a line of words, but a dense row of words running vertically.

With the official Chinese language of China...

There's even Braille.

Her long, thin eyelashes trembled slightly as they fell, and her fingertips pressed a little harder on the blind lines.

If the danger was directly stated here for the general public, there would be warning signs, but there are none.

But if there is a hidden danger here, and if someone wants to break through the defense and enter directly, they will encounter danger, then simply engraving the national flag and Chinese characters on the door is enough -

Why is Braille necessary?

Gu Xingmiao already had a guess in his mind.
