The cooperation with the boy was actually just Tang Zhen's temporary intention, but after contacting the boy, Tang Zhen was full of expectations for what surprises the boy could bring to him.

This young man is not simple, and he is now unknown, just because he is not rich in strength. Once he can gain power, he can definitely become a character.

As for how high he can stand and how far he can go in the future, it is not something Tang Zhen needs to care about.

For Tang Zhen, there were too many secrets in the building city. He had just felt many visual impacts after just his first contact.

But Tang Zhen also knew that these were just appearances, and he believed that more secrets must be kept in the hands of higher-level rulers.

Since you want to build your own building city, the more information you collect about this, the more beneficial it will be to you.

Only by being cautious and not doing unprepared things can you live longer and longer!

After pondering for a moment, Tang Zhen turned his head and left.

It has been a while since he left the Wanderer Town. I don’t know how Murong Ziyan, Qianlong and others are doing recently. Although Tang Zhen knew that without his permission, they should not leave the town, but wait for themselves to come back.

Tang Zhen thought while walking, but after walking for more than ten minutes, he found that he seemed to be lost!

This dark corridor seemed to be very long. He walked for so long but never reached the end.

According to the area of ​​the outer wall of the Heiyan Tower City that Tang Zhen observed, it was confirmed that there would never be such a long corridor inside, but the corridor in front of him was really stepping on his feet.

After pondering for a while, Tang Zhen took another step forward, but this time he did not focus on his feet, made a mark, and at the same time paid attention to the details in the corridor.

Half an hour later, Tang Zhen stopped, but a sarcastic smile appeared on his face.

"I really didn't expect that I was actually put on a trick by that little guy and led me into such an interesting place!"

Tang Zhen sighed secretly, but he didn't feel much annoyed in his heart. He just felt a little self-deprecating and didn't know that he had been plotted against by others.

For the past half an hour, Tang Zhen kept walking forward, but there was no sign of walking out of the corridor, as if this was an endless corridor with no exit.

In Tang Zhen's view, this corridor is full of weirdness. If you keep walking but have no answer, you may drive people with mentally fragile life to crazy.

If an ordinary person mistakenly enters this place, he will definitely not be able to get out until the day he dies.

But Tang Zhen is different. He not only has the application of the celestial black technology, but also has the knowledge far from the natives in the Loucheng world.

After entering this corridor, natives from another world may be at a loss and do not know the strange principle, but Tang Zhen vaguely speculated.

This corridor should be a Panlos staircase, or it can be called the Suspension Soul Ladder.

The shape of Black Rock City is square, with a huge square in the middle, and several floors of underground space below the building city for planting and feeding.

On ordinary floors, there are four corridors connected by upper and lower to ensure unobstructed passage.

This built environment provides excellent geographical conditions for the construction of the Panlos Ladder.

Perhaps this Panlos staircase was not built by Black Rock City, but appeared together after the building city was established.

Tang Zhen and Murong Ziyan have also heard that after each building city is built, a strange place will appear, and strange things will often occur in that place. Therefore, such places will be regarded as forbidden by the residents of the Loucheng, and even the rulers of the Loucheng prohibit residents from getting close to those places.

The basic principle of the Panlos step is that there are four stairs connected by four corners, but each stair is upward, so it can extend infinitely.

When you walk on this ladder, you are entering a deadly cycle with no end and you will never find a way out.

To break this cycle, you must break out of this frame, or destroy the walls leading people forward on both sides of the corridor, so that you can jump out of the Panlos ladder.

Tang Zhen recalled the scene when he and the boy entered this corridor, but found that he could not find any clues.

Although the Panlos Ladder was strange, a mere passage could not trap Tang Zhen. According to the previous methods, he had at least two ways to get out of here.

However, judging from the current situation, both methods have disadvantages.

Teleportation can take him away immediately, but when he comes back again, he will still be in place, so this method is not advisable.

The map can also teleport to any location within a hundred meters, but from the current scene displayed on the map, only the channel is displayed, while other places are pitch black.

He believed that this was definitely the strange ability of Loucheng to mess with it, blocking or disrupting the map, otherwise a powerful map would not only display images of the corridor.

Tang Zhen dared not teleport rashly. If the dark place was a high altitude position, Tang Zhen, who could not teleport continuously, would definitely fall from the air and then be smashed into meat paste.

So this method is also undesirable.

However, in addition to these two simple violent methods, Tang Zhen actually has other means.

First he can choose to blast and smash the corridor to an exit.

But if you do this, it will easily attract the attention of Black Rock Tower City. If you welcome a powerful Black Rock City powerhouse, you can see through your quantum invisible light curtain, Tang Zhen's situation will be dangerous.

Or he can use the data battle interface to scan and detect this corridor.

The reason why the data combat interface is expensive is not that it only has simple functions such as user physical data monitoring and weapon condition monitoring, but that it has more than 20 powerful branch options, but that Tang Zhen has never used it.

If these powerful functions are possessed by an elite warrior, the opponent can immediately transform into a war-level soldier king, which is enough to make any enemy frightened.

What Tang Zhen wants to use now is an option in the data combat interface.

The real-time terrain surveying and imaging function integrates radar, laser, sound wave and other functions, and can map the geographical environment within one kilometer in a very short time and establish four-dimensional holographic images.

When he activated this option, data suddenly changed from the waterfall at the edge of Tang Zhen's eyes, and at the same time, a clear three-dimensional image composed of countless subtle dots and lines appeared in front of him.

One minute later, the detection ended, and this four-dimensional holographic stereoscopic image also appeared in front of him.

After just one look, Tang Zhen was sure that this was indeed a Panlos ladder!

After carefully reading the image, Tang Zhen determined his position and slowly walked to a wall of the corridor not far away to stand in front of the wall.

There was a real wall in front of him. When he hit it with a stone, he would echo. Touching it with his hands was also a real touch, and it was no different from other corridor walls.

But Tang Zhen can be sure that the real exit of this Panlos ladder is here!

The survey results of the data combat interface will never go wrong. In the entire passage, there are only extremely tiny gaps on this wall, which happens to be a door.

Tang Zhen strode towards the wall, and even if he touched the wall immediately, he had no intention of stopping.

However, just as his nose was about to hit the wall, something magical happened, and the image of the hard wall was still there, but Tang Zhen felt that he had traveled through an empty door hole.

In a blink of an eye, Tang Zhen realized that he had left the Panlos stairs and walked into the corridor outside.

Looking back, the door with the soul-suspended ladder hidden seemed to be no different from other places. Even the hard corridor wall disappeared without a trace.

"It's indeed an interesting place!"
