It didn't take long for the mechanism to be found, and it was a semi-raised stone block on the stone wall, almost integrated with the stone wall, and was extremely cleverly designed.

After pressing the mechanism, a rectangular stone door slowly opened on the huge stone wall, and the stone door was almost integrated with the stone wall, which could not be distinguished, which made people have to admire the power of the person who designed the mechanism.

However, now is not the time to admire too much, Feng Yu, who was standing in front of the open stone gate, immediately looked inside the stone gate.

I saw that inside the open stone door, there was still a secret passage, and the walls on both sides of the secret passage were also inlaid with night pearls.

Feng Yu couldn't help frowning slightly, she didn't know where the secret passage in this stone gate led? After reminding the secret guards and asking them to be more careful, Feng Yu should take the first step and walk in cautiously, and let the dark guards behind her make marks in the same places as they walked just now.

The secret passage is very long, and the only difference from the previous one is that there is always only one, and there is no intersection or fork, as if it is twisting and turning.

In the process of walking, Feng Yu kept thinking, since there was so much blood on the secret passage that he had just come down, someone must have been injured between Xin Haoyan, Shangguan Feihong and Xie Wanting, so why was there no blood stain on the ground they walked all the way when they left there?

-

About a stick of incense after the time.

Ahead, another stone wall appeared, blocking it.

Feng Yu summoned the secret guard, and then searched for it on the stone wall together.

After a while, the mechanism on the stone wall was found.

The stone door on the stone wall slowly opened.

Feng Yu looked outside the stone gate first, and saw that outside the stone gate was another stone wall, and there was about the width of the secret passage between the stone wall that opened the stone gate.

Feng Yu squinted her eyes, became more and more cautious, and then walked out slowly, but saw that there was indeed a secret passage between the stone wall that opened the stone door and the other stone wall outside the stone gate, and there were a lot of blood stains on the ground only one or two steps in front of the left side of the secret passage, as if it was where they first came down.

That is to say, they walked for so long and then went back to the same place.

The Dark Guards had apparently seen it too, and they were frowning.

At this time, another stone gate opened, not far from the stone gate that Feng Yu and the secret guards walked out.

Feng Yu and the dark guards immediately looked together, only to see another group of dark guards who had been looking separately coming out of the newly opened stone door. Apparently, they also went around back to where they were.

When that group of secret guards saw Feng Yu and the secret guards behind Feng Yu, they were also stunned for a moment, and then quickly stepped forward and told Feng Yu all the situation.

After hearing this, Feng Yu thought about it quickly, and then looked around seriously left and right, looking at the blood stains on the ground on the left side and said affirmatively: "On the stone walls on both sides of the place where the blood stains are located, there must be the same stone gates, and a few of them must have entered there, so there is no blood stain left in other places." Find, find it immediately, be sure to find it as soon as possible, and be sure to ensure the safety of the prince, and there must be no mistakes. ”

"Yes. ”

The dark guards received the order, and immediately crossed Feng Yu and walked to the place where the blood stains were on the ground, and then looked for them on the stone walls on the front and back sides.

After a long time, a stone door opened inward on one of the stone walls where the blood stains were. Inside the stone gate, there is also a secret passage, and the ground of the secret passage is full of blood stains, and it extends all the way forward.
