What? Housekeeping Companies Can Also Save the World

"Baby, please don't move..." Qin He brushed away the squirming tentacles on the ground and said hello to the toilet full of fangs. One year after the arrival of pollutants, humanity was wiped out, but the survivors were forcibly recruited into the "Naiya Housekeeping Company". Qin He holds a ring with an unknown existence in his hand, exchanges random prayers for the remaining struggle in the apocalypse, and struggles to survive amidst the strange rules of "cannot open the door" and "keep wet at all times". When mirrors replicating human faces blended into the team, white flames that froze souls devoured teammates, and the never-ending train could not see the end, he discovered that: the price of promotion is mutation, and the end of trust is betrayal. And is the escaped Lichuan really still himself? Cleaning up is salvation—assuming you're not crazy yet.
