[No system + not invincible + growth flow + partial group portrait + not brainless + plot direction]
There is a place in this world that is dilapidated and cold all year round, called the wasteland.
Among humans, some people's bodies will suddenly undergo some kind of fatal mutation at a certain moment.
In order to survive, these people had to leave their original cities and come to the wasteland.
Under the cruel rules of survival, there are very few people who can successfully solve the mutation and leave alive...
If you go through darkness, you are still darkness.
Are you willing to move on, even if it's just to protect the light in your heart?
