221, there's also a tacit understanding.

For Aqi, opening an authentication portal is easier than breathing.

Anything used leaves a trace, and even if it wasn't used, being recorded still leaves a trace.

Aqi can be called up and used, so I'm too lazy to modify the internal code.

So the group of people outside timidly walked in, only to find that everyone had been knocked down. After a moment of shock, they rushed off to look for something useful.

Even if the group of people inside BCIA weren't as familiar with the situation as Liu Yun's group, they still knew a little bit about it.

I don't know the specifics, but I have a general idea of ​​where the good things are and where they need them.

The headquarters building is so big, with so many floors, each with its own needs, so they were basically all searched separately.

There is a demand, and there is also a tacit understanding.

Nobody knows how long they can loot this building, so not robbing it is naturally the best option.

Once we get what we need, we can see if we can collaborate and share the rest, or we can try a different approach. We can discuss that later.

There's really no need to argue in a place like this.

Perhaps it was pre-arranged, so even people who had a mortal feud would only use their eyes to kill each other.

He wanted to kill the other person with his eyes, but he still didn't make a move.

Suddenly, the entire building was filled with a lot of humming monsters. When you encountered one, they would just hum and move on. You had to hurry up and find your things.

Before long, everyone discovered that the entire building seemed to have no access control system; as long as there was a door, it would open as if it sensed a person.

The group looked on with anticipation, as if they had discovered a new world, watching each door that opened by itself.

Is the BCIA headquarters so easily accessible?

They believed that the headquarters building, relying on its status and position, might not be very vigilant.

But it's impossible to be so unimpeded...

Even in their own small hometown, things wouldn't be like this.

So, what exactly did that disguised Yan person who came in do?

If they used such methods at their home... well, it would probably be no different from entering their own home.

"Hey buddy, there's a safe here, locked tight, there must be something good inside."

Several people huddled together, using all their skills and techniques, seemingly trying to open the safe.

However, it ultimately failed.

Some people prepared tools to force it open, while others angrily slapped the door open, saying, "Can't you open it yourself? It's like a door."

Then, something amazing happened.

The safe's lock actually started turning by itself, and with a "click," the door popped open.

The group looked completely bewildered and remained motionless for a long while.

This works?

Aqi also told Liu Yun, who was on an adventure, about this.

Liu Yun was also puzzled: "Safes...they're usually not powered, right? And the lock? This works?"

Aqi: "But the safes in this building are basically equipped with chips, which can receive energy waves."

Liu Yun: ...So, why put a chip inside a safe?

Does it appear more intelligent and technologically advanced?

"For surveillance?"

Aqi: "Yes, the surveillance cameras here are really dense, they're everywhere."

"Besides, even if it's a mechanical lock, there are computers everywhere, so they can tell you the password."

"By using surveillance inside and out, scanning the internal structure with energy bands for attack and defense, we can find out the password."

The BCIA building is probably very lax on a daily basis, knowing that no one is likely to attack it.

However, this does not hinder their defensive arrangements.

The building's defense network is no longer a spider web; it's completely honeycomb-like, with no blind spots.

These things were transparent to Aqi, and there was nothing to hide about them.

Liu Yun: ...Sometimes, I really don't know whether to believe in science or not.

However, as long as our own technology remains at the forefront and is not easily broken, then that's fine.

Ultimately, it all comes down to ability.

The others were shocked by Yan Guo's methods; even the most foolish person would know that it couldn't be the BCIA itself that was so unprepared.

As for Liu Yun, she felt like she had been in the elevator for quite a long time.

The speed wasn't fast, and it was pitch black all around, which would be a problem for someone with claustrophobia.

The floor beneath your feet makes you feel very unsafe.

It started descending, paused at a certain depth, and then began to move horizontally.

Clearly, the people who built this underground space had some interesting ideas.

Liu Yun hadn't seen too much of the art of mechanical manipulation, so she wasn't particularly bothered by it.

If she absolutely had to give an evaluation, she could only say it's beginner level.

That's pretty basic.

In particular, all of these are powered by electricity.

Back in the Yunzhao Dynasty, people relied entirely on machinery, which has been in use for thousands of years... The fascinating artifacts of the ancestors of the Yan Kingdom are truly astonishing.

Aqi even complained, "The translation isn't a straight line, it's an arc, so it's probably disguised."

Liu Yun asked in confusion, "How... how could you not sense it?"

Such obvious centrifugal force!

Those who can go underground are all capable, with extraordinary senses; they can't be ignored.

Aqi was also puzzled: "This...I don't know!"

"However, it's clear that this place has been around for many years."

Hearing this topic piqued Liu Yun's interest. "About how many years?"

Aqi: "A hundred years is enough."

Liu Yun: "...That really takes quite a long time!"

"In those years, the United States experienced a significant explosion and leap in science and technology."

As he spoke, the floor stopped.

In the darkness, some buttons and screens lit up, and after a series of futuristic lights flashed, a door of light opened in front of us.

Unsurprisingly, there were a few people who had fainted and fallen down in the long corridor.
