Soon, the pond fish knew how they had proven their innocence.

The Sect Master, the Second Elder, and the Third Elder all stood on the high platform.

Seeing that there were thousands of disciples gathered below, some with familiar faces and some with unfamiliar faces.

They weren't sure they could find out who had sneaked into the library.

In this way, there is only one stupid way to use -

Polygraph.

Although it is a surprise to the snake, it is also the most effective way for now.

Only that person has a weak heart, and he will unconsciously show his feet......

After being silent for a long time, the sect suddenly raised his eyes to look at Mingrui who was standing at the front of the bottom, "Mingrui, all the disciples in the sect have arrived?" ”

Mingrui came out, his expression was solemn, and he bowed his hand: "If you return to the sect master, all the disciples of the sect have arrived, and no one has left the sect." ”

"Good."

The suzerain's jaw.

Then, his gaze seemed to sweep over the disciples in the audience at random, but in fact, he was spying on the cultivation of all the disciples.

"This sect master asked you to come here just for one thing."

Some of the disciples who had already heard the news did not react.

Just those disciples who didn't listen to what was going on outside the window and only remembered their cultivation showed a confused and dazed look, and they exchanged glances with each other one after another.

Sensing the uneasiness underneath, the sect master's face did not have any expression, and he said calmly: "Today's library was suddenly stolen, and that person is still holding a hand to enter the library pavilion......"

"This sect master remembers that the disciples under the Second Elder and the Third Elder have all received warrants before, but some time ago, those warrants have also been withdrawn."

"There are only a few people who still have the warrant in their hands......"

As soon as these words came out, the few disciples who still had the warrant immediately received a lot of attention.

They also looked stunned.

Obviously, they were also frightened by the sect master's words.

The seven disciples with warrants came out at the same time, kneeling on the ground in unison, and the eyes of the seven fell on the sect master: "Sect master, the disciples have not been to the library today. ”

"Sect Master, the disciple hasn't been to the ...... either"

"Sect Master, Disciple ......"

It was also a coincidence that none of the seven disciples had set foot in the Library Pavilion today.

The Second Elder and the Third Elder glanced at each other suddenly, but they didn't say anything, just waiting for the Sect Master to make a decision.

The sect master stretched out his hand, pressed his palm down, and motioned for all the disciples to calm down first: "Have you ever been to the Library Pavilion, this sect master can't just listen to your words to make a judgment. ”

"This sect master has prepared a polygraph treasure today, you ...... Every disciple of the Qingyun Sect had to come up and test it. ”

"If it's true, the treasure won't be unusual, and if you're telling a lie, the treasure will automatically trigger the protective barrier......"

Uh, isn't this the equivalent of a lie detector in a modern plane?

Chi Yu was stunned, and his round eyes looked at the rows of lie detector treasures placed in the center of the hall, and his curiosity suddenly popped up.

She tugged at Wei Yuan's sleeve and said in a low voice, "Ah Yuan, do you think that thing is reliable?" ”

Wei Yuan narrowed his eyes, and suddenly bent the corners of his lips, "Reliable." ”

Produced by Qingyun Sect, how can it be unreliable?

Mingrui and Chengmo were the first to undergo polygraphs.

First the senior brother and sister, and then the younger brother and sister.

Seeing that more than half of the disciples were about to be tested, the polygraph treasure still did not move.

Until Wei Yuan stood in front of the polygraph treasure.

"Wei Yuan, have you ever been to the Library Pavilion today?"
