Live Broadcast of Life and Death: I Rely on Rules to Solve the Mystery

I was forced into a live broadcast of life and death. Every time I entered a strange and dangerous place, I had to abide by a set of deadly rules. Violation is death. There is no heroine and no plug-ins. I can only rely on observation, reasoning and calmness to survive in the rules and traps. As the mission progressed, I discovered that behind all the strangeness, there was a huge dark web - and I was already the prey in this web.
