When you walk in, you can see that there is a stone gate in the innermost part of the cave.

Several people walked over.

That stone door looks like an ordinary stone, but in fact, it is not ordinary, and it is very hard, and it cannot be split with ordinary palm power.

Shimen seems to have been for a long time, exposed to the wind and sun, with a sense of vicissitudes.

In such a stone cave, there is a stone gate, but it is very attention-grabbing, ten people will be interested in the stone gate, interested in the inside of the stone gate.

"Pavilion Master, it was from here that Young Master Ye disappeared at that time. At that time, the young master of the night used his spiritual power to push this door, but he didn't know why, he was directly sucked in, and then he didn't come out. Seeing that Young Master Night was sucked in, the three of us also used spiritual power to push like Young Master Night, but there was no movement in the stone gate. ”

Thinking about that scene at that time, it was still quite scary.

In their eyes, it was a real door, but at that time, Ye Gongzi was really sucked in directly, from beginning to end, the stone door was never opened, but Young Master Ye also disappeared.

This phenomenon did not alarm them, but after being shocked, several people began to check it.

After all, in this world, there are all kinds of fantasy and strange things.

Zichen put his hand on the stone door and pushed hard, but not a trace of ash fell from the stone door.

She didn't know what the material of this stone gate was, but she could feel that on the other side of the stone gate, there seemed to be a strong force.

And Shimen sucked the second brother directly in?

Zichen thought the same as several teenagers, maybe this stone gate didn't really exist, it was just a trick?

However, Zichen quickly dismissed the idea.

Because she looked at it several times, she felt that this was a real door, and there was no sign of formation on it.

Shimen would suck the second brother in, but there was no reaction to them.

With the same spiritual power, the hands are placed in the same place, and the same method is used, but the final result is different.

No! Actually, they are not the same.

The second brother's spiritual power is not ordinary spiritual power......

"Young Master, what do you see here?" Nishiki, who was crouching on the side, suddenly shouted.

Zichen was stunned for a moment, looked over, and saw that the place of Ximu's finger was empty, and a groove appeared.

"Oh, why didn't I see it at the time?" The three teenagers saw the groove and said in amazement.

At the beginning, they searched this cave inside and out countless times, but they didn't find the groove.

Zichen squatted down and carefully examined the groove.

The groove is just above the stone door, close to the ground, and it is difficult for people to spot.

"It should be the place to insert the key." Zichen Road.

It's just that since this door needs a key, why was the second brother sucked in directly?

"It's like a jade pendant." Nishiki said again.

Zichen nodded, indeed, looking at it from the notch, it should be a piece of jade pendant.

What is the secret of this door?

Since you can't push the door open with brute force, you can only use the key.

But what if they don't have the key?

Zichen carefully examined the groove, and suddenly, Zichen's face was slightly strange.

No way?

"Childe, what's wrong with you?" Ximu first saw Zichen's expression and asked worriedly. The other three teenagers looked at Zichen with the same concern.

Zichen shook his head, looked at the groove again, and took out a jade pendant from the purple ring.

"Ah, it's exactly the same!" Nishiki took a look,
