My Doomsday Can't Be so Desperate

The apocalypse breaks out and you get a system that can upgrade everything. Is this an RV? It is obviously a villa inside, with the cute little girl 2b, the cold little girl No. 18, The Tang knife that can chop zombies by herself, mutated zombies, violent zombies, and mutated bugs. In this doomsday, everything except humans is your enemy. Lizards, crocodiles, and snakes are collectively returning to their ancestors. The terrifying dragons are rising again. Can the orcs still become the overlords of the world? The zombies in this apocalypse are very violent, but the people in this world are very cute. The humans in this world help each other. There is no other doomsday intrigue, for the sake of the human race. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
