Zhou Yong didn't say much, instead he directly took out the jade pendant on his chest. Afterwards, in front of Cao Sui, he knocked the jade pendant on the ground lightly.

The jade pendant broke into two pieces immediately, but it was not completely broken. It was more like a small box folded in half.

And in the center of the box, there happened to be a relatively petite but very exquisite key.

"My father has considered these things a long time ago. He was afraid that I would not take them seriously, so he wrapped them with a jade pendant. In this way, I don't worry about forgetting the key, and at the same time, its existence won't make me remember it. I only think of it when it is most useful, and of its value."

"Let's go, let's go in."

As soon as the words fell, Zhou Yong took out the key and inserted it into the hole. As the key was twisted, the sound of Kakaka came out of the hole.

Afterwards, the stone door moved slightly, and one of them opened slowly inward.

Cao Sui looked at Zhou Yong in front of him, feeling extremely envious in his heart.

It is said that one must have a good father, but this is true.

Look at the family. Not only did they grow up with a golden key in their birth, but even many things in the future were clearly arranged.

In other words, it's not that my father is not good enough, but someone else's father is too fucking fierce.

Sighing, envy is nothing but envy, life has to go on.

Soon, one side of the stone gate was completely opened.

There was a burst of cool air from inside, and several people quickly got in.

It was pitch black, but the darkness did not last long, and then Zhou Yong found a mechanism behind the door, and as soon as he pressed it, the stone door on the half that was open was closed immediately, and the passageway was also instantly closed. There was a fire.

Those were oil lamps hanging on the wall one after another.

There are a large number of them, and they are neatly arranged. When they light up, the entire tunnel instantly becomes like daylight.

"The ventilation here is very good, so even if there are too many lights, the temperature in the secret passage will rise, but it will drop soon." Zhou Yong smiled proudly: "In addition, from now on, you can Feel free to speak, even sing, because no one will hear our voices inside."

Cao Sui went to the wall and observed the wall. The walls were all made of stones.

He touched these stones with his hands. The stones are very hard. At the same time, from the feel, these stones should be very big. If they hide inside, it is indeed difficult for the sound to spread.

"Don't worry, the thickness of each stone is about one to two meters. Not only can it provide perfect sound insulation, but most importantly, it can also provide us with strong enough protection."

After finishing speaking, he looked at the guards beside him.

"You guys give it a try and call me with all your might."

Many of the situations in the secret passage were told by his father to him, and Zhou Yong actually didn't know the extent of it.

Therefore, he himself has a strong curiosity.

The guards look at me and you, and don't know what to do for a while.

However, after receiving Zhou Yong's reaffirmation, several people lined up and found a certain place to target.

In the next second, several people joined forces and directly blasted at the stone! JrNovels.com
