Apocalypse: I Had 100 Kids, What's the Big Deal?

[Sci-fi apocalypse + virus reigns supreme + many heroines + decisive and ruthless] After being cheated on and then brutally murdered, Shi Qingquan is blessed with incredible luck when an unknown virus attaches itself to him. The virus is a bit like a System, but it has a bad temper. The slightest thing it doesn't like makes it go to sleep, and it's hard to please. It even gave itself a human name: Aibobo. Aibobo's tastes are worlds apart from Shi Qingquan's, and Shi Qingquan ends up falling for women he shouldn't love. “Bobo, forcing things like this isn't right!” [Quanquan, it's the apocalypse. Who gives a damn about romance?] As he goes around fathering children, the world quietly begins to change. To save humanity and the Earth, Shi Qingquan and Aibobo fight side by side, driving back every last creature from another world.
