Qin Wuyan went straight to the back of the door.

Si Nanyan and others followed them in without hesitation.

"How dare he?"

At this time, some people don't understand.

Why did Qin Wuyan dare?

What if all the keys are fake?

After all, I could have created such a scam before.

Directly kill a powerful person in the Void Refining Realm in seconds.

It also allowed many strong men to enter the door.

I don't know what's going on now.

Such existence.

All ten keys are fake, and it is really possible.

But Qin Wuyan rushed in like this.

Many people don't understand.

Don't dare to move.

"Young brother, you're sure that the last key is real?"

He Wenya was also asking Qin Wuyan at this time.

Qin Wuyan nodded, "I think it's true!"

"You think?"

He Wenya was a little curious.

Why is this key real, my junior brother?

"Well, because when I saw this key, I also showed it to you for the second senior sister!"

Qin Wuyan asked back.

"Well, I saw it. Quality materials and other things are all ancient!"

He Wenya nodded.

This is certain that the key really belongs to the ancient secret realm.

But even so, it cannot be explained that this key is real.

Because the other nine keys also belong to ancient secret realms.

It's also old.

"Yes, I was not sure about it at first. Even the scroll contains records of ten keys, and even accurately marked the correct key!"

Qin Wuyan said, "That key is exactly the same as our key!"

"Then you are not afraid of it being fake. After all, the real keys and scrolls are very fake in themselves. When you used those keys just now, there were also those who opened the door, but they all turned out to be fake!"

He Wenya still didn't understand.

Just because of these things, I believe it?

The other senior sisters were also a little curious.

Is this how the younger brother judged?

"Of course it's very likely, because I found that the other nine keys, as described in the scroll, were similar, but a little less!"

Qin Wuyan smiled slightly.

Hearing this, the senior sisters were all curious.

"What's missing?"

He Wenya thought about it.

I don't seem to feel anything missing.

"Formation!"

Qin Wuyan said.

Two simple words.

It surprised He Wenya and others directly.

"Formation? The younger brother said, is there a formation in that key?"

Chu Ziyue was also very surprised at this time.

Because she had also received the keys before.

But she didn't find any formation!

"I also discovered after carefully studying the mental power. A fifth-level formation is hidden in a small key, which is too powerful!"

Qin Wuyan also sighed at this time.

It is probably a sixth-level or even seventh-level formation master.

Only then can it be done.

"Hiss, fifth-level formation?"

Chu Ziyue was also a little surprised at this time.

This is not something that ordinary people can do.

"That's why you asked you to help them open the door?"

Si Nanyan also asked at this time.

"Yes, when I used my mental power to catch their keys, I also looked carefully. There was no formation in their keys, but there was a strange fluctuation. I don't know what it was, it seemed to be the same as some fluctuation on the door."

Qin Wuyan thought for a while and added: "It may be this fluctuation that caused the emergence of those mechanisms or other traps behind the door."

"So that's the case. So what is the use of this formation?"

Mo Siying also asked.

What is the use of this formation in the key?

"It should be a trapped formation!"

Qin Wuyan thought for a while and said.

"Handled?"

Mo Siying was stunned.

Add a trapping array to the key?

Isn't that trapping people?

What's the use?

"The trapping array should not be to trap us, but to trap all the mechanisms behind this gate!"

Chu Ziyue said.

Qin Wuyan nodded, "Fifth Senior Sister is right. This trapping array actually traps all mechanisms. In other words, if this trapping array is not broken, we will be safe here!"

"So that's how it is!"

Mo Siying nodded.

"But this formation has time limits, so I came in when the door was opened!"

Qin Wuyan explained again.

Upon hearing this, Mo Siying nodded, "It's still my junior brother's wit. Those people are still seeing if we're really finished!"

"I'm only 90% sure!"

Qin Wuyan said helplessly.

He dared not be sure.

Because there may be something he would guess wrong.

But now it seems.

It seems to be true.

"If you are rich and noble in danger, you can try it if you are 50% sure, let alone you are 90% sure!"

Si Nanyan said.

Hearing this, the others nodded.
