[Apocalypse + Rebirth + No zombies + Space + Not a saint]
As the apocalypse strikes, Xiaoran is betrayed and murdered by his wife's family, who then cannibalize him. Only in his dying moments does he realize that his son is not his own flesh and blood; he's merely a pitiful scapegoat.
Yet, he finds himself reborn three months before the apocalypse, endowed with a vast otherworldly space!
He starts by divorcing his malicious wife, wins a lottery jackpot, enters the stock market, earns billions, builds a secure bunker, and hoards vast amounts of supplies.
This time around, he's determined to exact ruthless revenge on his ex-wife's family and refuses to be a humble lapdog ever again!
