Evacuation: Rules for Changes

"Evacuation + Sudden Change" The world has gone crazy, the smell of decay is everywhere, people are all terrified and on tenterhooks every day. Survive? But what if we can survive? Twenty years ago, Team 068, codenamed "Tianji", accidentally entered a laboratory during another survey. The bacteria collected failed to survive, causing a virus outbreak. Twenty years later, people discovered that the situation did not seem to be like this. That day, they discovered a secret. These terrifying monsters were getting stronger. Some of the teams they sent had not returned, and those who had returned had gone crazy. To be precise, the world had changed for some unknown reason.
