After Nangong Ming also traveled to the small universe, An Kang took back the small universe and began to study the current top priority - how to get out of this place below the level with the carriage.

It's definitely to the ground. This is one thing that Ankang is very sure of. Otherwise, how could this human-built building have its entrance underwater? Is it for fish?

Although I don't understand what this black tower and the six black pillars are for, I can definitely have something to do with the jade pendant around my neck.

When Ankang approached the Black Tower again, he found that there was an anomaly on the Black Tower that he hadn't noticed just now - a bright pattern appeared on the black tower. Looming, not very clear.

Ankang guessed that this bright pattern was related to the jade pendant, so he took the jade pendant off his neck and approached the bright pattern. As the jade pendant approached, the bright lines became brighter, and finally a pattern was revealed.

The three of them couldn't help but glance at each other after seeing this clear pattern, because this pattern was a top view of the black tower and the six black pillars. Moreover, the black pillar is also marked with serial numbers such as one, two, and three.

An Kang held the jade pendant and walked to the black pillar marked "One". A bright stripe also appeared on the black pillar, small, round, and looked particularly like a button.

In the spirit of non-stop exploration, Ankang took his thumb and pressed it towards the button-like shape. The stone was recessed inward, and a noise was heard in the pillar.

Ankang brewed as usual, and pressed the button on the black column marked "two". Until the buttons on the six black columns were pressed.

At this time, I heard a sound in the distance, like the sound of stones rubbing against the ground, and the source of the sound was in the hall below.

An Kang asked Nangong Ming and Xiao Liu to stay near the Black Tower, and he used his finger to light a flame as a torch to check the hall below, and found that the entrance passage they came in from the water was closed by a boulder.

The only entrance here is sealed, which makes sense to cause anxiety and even fear. But Ankang didn't.

Because the closed entrance was a dead door for Ankang. It's the same whether it's sealed or not.

The closure of the entrance to the bottom of the water may indicate two different conditions. The first is that the three of them are trapped in this underwater structure, and the second is that there must be a passage to the surface.

Although Ankang didn't know if he guessed right, he used empathy. Again, it is based on the principle of the communicator in physics. Before the passage to the ground level can be opened, the passage connected to the water must be closed, otherwise the entire hall will be filled with water.

Now that the access to the bottom of the water is closed, it is a matter of how to open the access to the surface.

Ankang made a decision that he didn't know if it was wise or not. He opened the door of space-time in front of the carriage, then drove the carriage into the small universe, and then came out of the small universe, closing the gate of space-time.

In this way, the carriage that was stopped at the bottom of the steps and could not come up could be put into the Jade Perry and carried with him.

I'm so witty!

An Kang, who was in a good mood, hummed a little song from the lower hall and returned to the upper hall of the Black Tower, telling Nangong Ming and Xiao Liu that the entrance they had just entered was closed by a boulder.

Nangong Ming and Xiaoliu were stupid: "What can I do?" ”

"Let's have something to eat first, and I'll figure it out. I don't know when it will be. ”

Ankang distributed the dry food taken from the carriage to Nangong Ming and Xiaoliu, and walked around the Black Tower and Black Pillar by himself.

At this time, An Kang heard Nangong Ming's shout: "Master An, come quickly." ”

Ankang walked over, only to see Nangong Ming pointing to the wall and saying, "Look." ”

An Kang stretched the flame on his finger forward, and there was a rectangular gap in the originally smooth wall. Judging from the shape of the gap, it looks like a secret door.

An Kang stuffed all the uneaten cakes in his hand into his mouth, and beckoned Nangong Ming to push the stone with him. The two of them tried their best, and no matter how much they pushed, the stone did not move.

At this time, Ankang noticed that a small stone protruded from the ground in the corner of the wall. As soon as he stepped on it, he heard a "click", as if something had been touched.

Ankang pushed the stone again, and the stone was easily pushed away. This is indeed a secret door. Behind the secret door reveals a secret passage that allows two people to pass side by side.

It seems that this secret passage is the passage to the surface.

The three of them glanced at each other, and their faces couldn't help but show a look of relief.

They took the things in the hall, and Ankang started with the torch that evolved with fire-based skills, and Nangong Ming and Xiaoliu followed Ankang and walked in turn along the secret passage.

To the great surprise of the three men, the secret passage was not straight, but zigzag. It's just a twist and turn, and the secret passage is still very long.

They walked for a long time and did not find an upward passage, but always walked on a horizontal plane. I don't know when I'll be able to walk on the ground like this.

After walking for about half an hour, the three of them had not yet reached the end of the secret passage.

People are already suffocating in this cramped space, and there is not enough oxygen in the secret passage, plus walking for a long time consumes a lot of physical strength, and the three of them are stuffy and tired.

After all, this is a city occupied by wild beasts, and who knows if fierce beasts will come out of this small passage? If the beast strikes them back and forth, the scene is really indescribably beautiful.

And this secret passage is so small, there is no way to drive the carriage out of the small universe. Although it is true that you can hide in the small universe in case of emergency, you can't stay in the small universe all the time, right?

The three of them continued to walk forward with apprehension. Finally, we finally reached the end of the secret passage.

However, when the three men saw the end of this secret passage, their hearts sank.

At the end of the secret passage turned out to be a wall, blocking the secret passage tightly. And this wall is a whole big rock. Not even a crevice.

An Kang and the others studied for a long time, but they couldn't find any mechanism to open the door or anything like that.

At this time, they suddenly heard the sound of "boom", under the echo of the passage, it was like the sound of thousands of horses galloping. The sound stopped after only a few seconds, and a dead silence followed.

Ankang looked around again, and said to Nangong Ming and Xiaoliu: "Are we in the scheme?" ”

Nangong Ming nodded, he also felt this way.

"Go back!" An Kang greeted and ran back with Nangong Ming and Xiaoliu.

Ankang holds the torch in his right hand and the five fingers of his left hand are spread out, ready to cast the Force shield at any time. Nangong Ming, who ran at the end, ran for a while and threw out a thorn bush behind him. In case a beast sneaks up behind.

This run lasted another half an hour. But he hasn't escaped from the secret passage yet.

It takes the same amount of time to run back as it does when you come, and when you come there you are cautiously exploring the path, and when you go back, you run wildly. It stands to reason that he should have run back to the hall with the Black Tower a long time ago. However, there is no end to the secret passage.

"Hit the mark! Really hit the trick! Despite this, Ankang did not stop at all.

Another hour passed.

In the secret passage. An Kang, Nangong Ming and Xiao Liu sat on the ground to rest.

In the process of running back, they heard a "boom" sound similar to the galloping of thousands of horses more than once. At this time, An Kang could probably guess what the sound was—the sound of the secret passage moving.

Whether you come or go back, there is only one way to this secret passage, and there are no other branches. But the reason why you can get lost now is that there is only one possibility, and that is that some parts of this secret passage can be moved.

It's like a fork in the rails of a train. The section of track at each fork is movable. When a wrench worker or wrench moves the track to a different location, the train that travels along the track will go in a different direction.

We're lost.
