The Dimensional Book of Collapse

Qin Mo traveled through time
Good news: He has no attachment to his own world.
Bad news: He traveled through a world that collapsed
Good news: There is a system
Bad news: The system is written by myself
As an ordinary person who came to Changkong City where the survival rate of ordinary people is infinitely close to 0, Qin Mo is faced with a major choice in life.
Is it to escape from Changkong City before the third collapse, live your life as an ordinary person, live in fear, and then wait for the protagonists to solve everything?
Or should you throw yourself into the collapse, interfere with the main storyline, and use your own strength to gain a hope of survival?
Qin Mo chose the latter. The only reason for this young man, who had no worries in this world, to live was to live itself.
