He repeatedly watched the emails he had once sent to himself, looking at the videos inside, trying to find any clues.
After spending two hours studying the videos, Fu Shihan's body suddenly stiffened, he pressed pause, and noticed something odd.
There was a letter in the video, a very small one, on the bookshelf behind him, barely noticeable unless you look closely.
Fu Shihan noted down this letter, reopened another video, and similarly found a letter in it.
Different positions, different contents.
He had a brainwave and decided to rewatch all the videos from the beginning, and was glad he hadn't deleted these things earlier.
All night long, he sat in front of the computer in the study.
As dawn broke, a new line of text appeared in the notebook beside him.
It was a URL, not an address of any public webpage, an unfamiliar combination of letters and numbers.
He quickly opened the webpage and entered the contents. After clicking enter and entering, his eyes flickered slightly.
