In a crisis-ridden world, many mutant species have appeared. In order to deal with these, many different organizations have appeared one after another to find light in this dark apocalypse. Chen Lin, code-named 3472, is a member of the search and rescue organization, and Si Nian, code-named 4437, is a member of the hunting organization. The two unrelated people met in a crisis, helped each other in the crisis-ridden apocalypse, and worked together to save the world from the abyss.
Intention: There will be a savior in the last days
