There are three rows of triangular buildings, each of which corresponds to the center of each floor of the underground space. The row they were in before was in the outermost row, the farthest row from the center.

Ling Ruo had already used his divine sense to explore the underground space, the top three floors were compartments like beehives, the fourth floor was a vertical downward opening, and the fifth floor down could only be seen faintly.

From this point of view, the devices for soul dementoring and transforming those cores should be on the fifth layer, or below.

If you want to go down, you have to go down from the fourth layer, and the fourth layer, which is right in the center of the entire ancient city, is far away from the huge skeletons on the ground.

If you enter through the outermost triangular building, then Ling Ruo will need to go around for a long time to reach the most central position, and I don't know how much time will be wasted.

Therefore, Ling Ruo decided to go down from the row of triangular buildings closest to the center of the ancient city, and the middle section of the road went directly to the ground.

The road on the ground was easy to walk, and the distance of a few miles did not take Ling Ruo much time, and when she just landed at the door of the selected triangle building, she suddenly had a very subtle feeling, as if something was brushing her body, causing fluctuations in the surrounding aura.

The anomaly soon came to an end.

Ling Ruo paused, only to realize what had just happened, and suddenly broke out in a cold sweat.

It must have been the Soul Device activated!

Fortunately, she is not an ordinary person, otherwise she would have died suddenly.

However, this also made Ling Ruo completely relieved, it seemed that this device really couldn't help her—at least it couldn't capture her soul.

After settling down, Ling Ruo stepped into the triangular building.

It's just a foot away, but it's completely two feelings, and after entering, she obviously feels that the temperature around her is a lot lower, just like when she jumped into the hole of the ground sink before.

Ling Ruo went down the stairs step by step, there was no light at all below, it was extremely dark, Li Weitian and the others, who had opened their eyes to the late stage of body refining, couldn't see far with the help of the Night Pearl, let alone Ling Ruo, a young monk who could enter the middle stage of body refining.

Moreover, the aura jade bricks that she had originally picked up in the labyrinth had already been used when she entrusted Li Weitian to set up the array, and she was now in the darkness where she couldn't see her fingers, and she was completely blind.

However, she still has a divine sense, and when her divine sense is displayed, she can see it more clearly than what can be seen with the naked eye.

It's just that after sweeping the whole room at once, she was a little confused.

The partition room here was the same as the one she had seen beneath the hole in the sinkhole, a basement with only four walls and two boards (ceiling and floor), and nothing.

This "what" includes doors, windows, and any place that can be shuttled.

On the other side of the hole in the hole, she saw a hole in the wall, but the hole was obviously just broken, and it should be the masterpiece of Li Weitian's group.

There are no doors and no windows, how do you get from this secret room-like compartment to the fifth floor of the underground space?

Could it be that the souls that were taken away passed through the walls?

But the soul is a very fragile thing, and when it touches the real thing, it will consume itself, and this wall will pass through, and before it enters the channel of transformation, it will already consume itself.

Besides, Li Weitian, Yin Pengfei, and even He Kong have all come down before. He Kong also circled inside, and returned to the ground.

They can't just pass through the walls!

There must be a hidden passage here!

After thinking about it, Ling Ruo flicked his ten fingers and used the Ten Thousand Flower Fist to gather the aura, making a faint white phantom.

This false soul shadow is not an illusion, but a simulation with aura, which is very close to the real soul in nature.

If the real soul is a natural pearl, then the fake soul shadow that Ling Ruo simulated is a pearl pressed from scattered pearl powder. The value of the two is not the same, the formation is different, but the essence is very close.

This underground device should not be able to be deceived with illusions, but I don't know if the fake soul can fool it.

As soon as the white phantom was formed, a sudden suction force struck, it shook violently, slammed into one of the walls uncontrollably, and then really passed through the wall and disappeared in front of Ling Ruo.

Ling Ruo was stunned for a moment before he reacted, and hurriedly rushed over. She originally wanted to see it clearly, but she didn't expect to use too much force just now in a hurry, and she couldn't restrain her strength, so she slammed straight into the wall.

To her surprise, the imaginary impact did not appear, and she actually followed through the wall.

After stabilizing his figure, Ling Ruo had already entered another compartment. She looked back and saw that the wall she had just drilled through was complete, and there wasn't even a small hole that could have gotten through mosquitoes.

Not only that, but she also touched it, and the wall was very solid. She couldn't help but bump it with her body, so much so that she bared her teeth and didn't hit it.

What's going on?

Seeing that the white phantom had burrowed into the opposite wall again, Ling Ruo didn't have time to stay here to continue his research, so he hurriedly followed.

Walk through the wall again!

Similarly, when Ling Ruo collided in reverse, he couldn't hit it.

"One-way passage, there is entry and no exit." Ling Ruo finally remembered this sentence.

The white phantom disappeared into the wall again, and this time Ling Ruo was not in a hurry to catch up. Because it crashed into the same position three times, the wall closest to the center of the ancient city in each compartment, in the corner of its lower left corner.

It seems that this one-way channel should be in a fixed position.

So this time, Ling Ruo walked over slowly, wanting to experience the feeling of going through the wall. It's just that the wall is there, and when she passes through it, she can't touch anything, as if there was nothing there.

After connecting several walls like this, this time Ling Ruo still wanted to pass through in the same position, but he knocked out a big bag on the door of his head.

She covered her forehead with one hand and groped around, but she still only touched the solid wall.

How did the passage disappear?!

No, maybe from this interval, the position of the channel has changed!

Ling Ruo re-condensed a white phantom, and as soon as it appeared, the phantom was sucked into the center of the room and slammed into the ground. Suddenly, her eyes lit up, and it seemed that she had arrived in the middle of the ancient city!

Ling Ruo hurriedly ran to the position where the phantom was sinking, her feet were empty, and a sense of weightlessness hit, she hurriedly waved her hands, wrapped herself in spiritual energy and slowly fell, and finally fell into the compartment room on the second floor below.

As soon as Ling Ruo landed, he found that the phantom was slightly staggered and continued down.

She followed and descended to the third floor.
