"We are a brother in the face-slapping group. Something might have happened." Zhang Fan looked a little gloomy.

At this time, he had to think about the worst!

"What happened to He Yang?" Brother Hei and the others screamed!

"Brother Hei, let's go! Find the senior!" Zhang Fan whispered!

Soon, Zhang Fan and his group came to a villa. In the villa, there was a huge conference table and more than 20 computers!

"Brother Hei, you are responsible for investigating the surveillance system within our Tsinghua University. From today forward, we will see when the senior last appeared in the school. I will investigate outside the school!" Zhang Fan said, his fingers flying!

"Snap, snap, snap!"

The violent keyboard sound suddenly sounded!

"I found it. The last time He Yang appeared was twenty days ago!" Hei Ge said.

"No, my surveillance outside the school found that He Yang was out in the restaurant five days ago!" Zhang Fan's voice was extremely low!

What does this time difference mean?

This shows that the surveillance system in the school has definitely been tampered with!

"Check if there are any traces of the surveillance being overwritten!" Zhang Fan's heart sank to the bottom!

He Yang, what happened?
Chapter completed!
