(Single female protagonist, superpowers, no system, no idea, no brains) The civilization of the previous era has been destroyed and buried deep underground. Human beings will call the day when they come out of the underground shelter the new calendar. In the 417th year of the human new calendar, the fifteenth blood moon will come every month, and the human body will be dissolved and reorganized into irrational monsters. Hu Lai, a street boy adopted by an old postman couple, inherited his job and became a city-building postman. Due to a delay in a mission, he was stranded in the wild. The mail truck was knocked over by a mandrill and his body was irradiated by the blood moon. After dozens of body dissolution and reorganization, he did not become weird. Instead, he awakened a suspected "cell reorganization" power (rapid repair, enhanced body strength and power, dozens of times that of ordinary weirdness).
From then on, he embarked on the path of defeating monsters and upgrading, and gradually found the truth about the destruction of the world.
Three punches to crush the world-destroying soul, brother, I am an alien.
Hu Lai: "Alien? Do you know the value of the terrifying Ape erectus?"
It looks okay so far
