An email from Hacker 2!

At night.

The Internet Surveillance Bureau.

Zhang Ye's singing was ringing out from the livestream playing in the office. The staff of the Internet Surveillance Bureau who were working overtime and quite a few others were watching the livestream of Zhang Ye's "The Final Concert."

"This is awesome!"

"I like him so much!"

"Teacher Zhang has always been my idol."

"It's a pity that Fang Xiaoshui and the others can't watch this."

"Our comrades of the First Department are so unlucky."

"They still haven't found out who 2 is?"

"All 16 of them have been investigated, including Director Dong, but it doesn't seem to be any of them."

"Hai, I wonder how more many days we'll have to work overtime like this. It's a good thing we have Teacher Zhang's concert to watch tonight and kill our boredom."

Out of the blue, an alert sounded on the computer.

It was the sound of a new, incoming email.

"Eh, an email?"
