"Something seems wrong, is this a treacherous realm, or something else?"

In the dark corridor, Li Yu stopped.

His face was a little solemn, and he quietly felt the inexplicable atmosphere around him, and he didn't move forward.

It's a gut feeling for no reason, like a person walking in a dark wilderness with an infinite abyss in front of him.

Although ordinary people cannot observe directly with their eyes, they may be vaguely aware of it.

Because if you take one step forward, you will be crushed.

That kind of life-and-death moment, the sense of imminent crisis is enough to alert some intuitive people.

It's just that Li Yu still can't determine the source and cause of these things, let alone what they are.

"I have a vision of the truth, but I can face many dangers brought by treachery......

But there are some things that are also powerless and require the help of some special means.

For example, similar to guns and ammunition in previous lives, and unrelated to trickery!"

Li Yu guessed, opened his eyes, and tried to see through the void.

The power of the Void Prison Surge of the Eyes made his gaze spread in all directions like a tangible thing.

In the darkness, a hazy white light penetrated the walls and the human body, spreading with a strange power that ordinary people could not see with the naked eye.

More details are visible in the vicinity, like high-definition pictures, in detail.

"There's no one here, and there's no ...... here."

"Huh? Although there is no one guarding this place, there is something like this buried, as if it is a strange treasure, but it does not look like a strange treasure......

Suddenly, Li Yu discovered something special.

It was installed in a very private place in the corner of the wall, only the size of a walnut.

He didn't sense any treacherous power in it, but there were slight ripples in the air as the patrolmen passed by.

The strangers among the patrolmen seemed to rub against them, sending out a slight change.

"As expected, the device itself has no treacherous powers, and I can't directly detect its anomaly!

This should be a clever thing made by Tiangang Hall!"

If it weren't for the insight from his previous life, Li Yu would have been studying for most of the day, and it would be difficult for him to think of this.

"Although there are no scientific and technological products that I am familiar with in this era, because of the existence of the 'craftsman god', Emperor Delong also has many things that transcend the times.

It's kind of like an infrared-sensing device.

No wonder it's so dark here, it's to prevent people from seeing."

In such an environment, even if someone can see the night as day, it is possible to plant it in its hands.

"Although my eyes can directly see the treacherous, this kind of ingenuity is somewhere between a strange treasure and a technological creation, and if you don't look closely enough, you may really ignore the past."

Li Yu immediately dived into the Strange Domain again to avoid being detected.

After doing this, he had the time to continue thinking.

Originally, the defense methods of the Tiangangtang people did not mean much to him, this place was just like the backyard in his house, he could come and leave if he wanted.

But at this moment, he finally felt as if some glass slag and iron nails were buried in this backyard.

If it weren't for the limitations of Tiangang Hall itself, it would be impossible to really reproduce all the scientific and technological creations, then it would be completely possible to install night vision devices, and the entire underground palace would be completely blocked for monitoring.

Or, a variety of acoustic wave detection, laser sensing devices......

The ancients weren't stupid.

As long as they are given the right conditions, they can develop scientific and technological products that are not inferior to those of their previous lives.

"If it's possible, I really want that Lao Deng to write the memory that the emperor in charge should have, honestly, don't do things again!

As for the ambitions that shouldn't be there, let them go with the wind.

This world is chaotic enough, dangerous enough

, and being tossed around by such high-ranking and powerful people, it is simply that the situation does not collapse fast enough."

Seeing this strange product of the combination of treachery and technology, Li Yu knew that this must be a by-product of some kind of experimental development direction.

But after Li Yu sighed secretly, he could only silently look for the loopholes in the line of defense in front of him.

Soon, he realized that there was no point in doing so.

Because in the passage ahead, almost every corner is covered with the same thing, and there is no flaw at all.

"It's really rough and direct!"

This is probably the so-called quantitative change leading to qualitative change.

Li Yu thought for a while, and once again used the power of the Trick Domain.

If the front is compared to a pool of water, the Trick Domain is the best way to wrap the whole body without touching a drop.

It's not good for him to make a big move, and he directly drains the pool, and it turns into a strong attack.

"It's better not to expose it for now."

The use of the Trick Domain is a very big consumption for ordinary Inhumans, and he probably understands the reason why the other party deploys this means of defense.

It is to force people to use trickery and use this kind of massive consumption to pass through the defense line.

When ordinary people see it, they should retreat.

The ghost knows how long the road ahead is, can you drive all the way to the treacherous realm and stick to it?

But fortunately, his skills are different from ordinary people.

He believes that he will definitely last long enough!

As long as it exceeds the construction capacity of this era, Tiangang Hall will have no choice.

……

With the help of the trickery, Li Yu slowly continued to move forward. Like a ghost again, he came to the passage of the lower level.

There were no more guards here, just a chilling and inexplicable oppression.

"Something seems wrong, is this a treacherous realm or something?"

In the dark corridor, Li Yu stopped, his face was a little solemn, feeling the strange atmosphere coming from all around.

……

"Wait, it seems to feel like something is wrong!"

An inexplicable hint of restlessness flashed in Li Yu's thoughts.

The dark passage as always, the eyes as always open, probing the surroundings.

Inexplicable familiarity, inexplicable sense of déjà vu......

It's as if you've gone back to a certain starting point again!

After some reconnaissance, he saw the strange reactions around the patrol with his eyes.

"There's that kind of reconnaissance that spreads all over the place......

He endured the feeling of discomfort and once again carried out the treacherous realm.

Li Yu seemed to have forgotten what he had just been thinking about, and still continued to move forward.

Once again, the passage from the lower level appeared in front of him.

The pitch-black hole is like an infinite abyss, and it is like the mouth of a giant beast, ready to be devoured at any time.

Li Yu looked at this scene, and a certain thought was like thunder, illuminating his thoughts.

"That's not right! It shouldn't be like this!

I'm stuck in a maze of ghosts hitting the wall
