I Rely on the Red Line to Break the Situation

The rules came and the world collapsed. The red line in the corridor, the guests at the breakfast bar, the knock on the door late at night... Behind every rule is a life-threatening mystery. My name is Chen Mo, and I can see the "red line of death" that others cannot. In order to protect my disabled father, I was forced to step into the forbidden area of ​​​​the rules, fight against the mysterious "lawful ones". The red line points to the way out. I will become the last rule observer, guarding the last trace of order for mankind in this collapsed world.
