Apocalypse Supremacy: Starting by Taming a Villain's Mount

[Rebirth + apocalypse + System + ruthless and decisive + dark] Goody-two-shoes, stay away!!! Qin Hao, who had struggled to survive for three years in the apocalypse, was reborn ten days before it began. “Ding! The Apocalypse Conquest System has been activated. Host attributes have been compiled. Please check them yourself.” “Ding! Random mission triggered: Obtain a white lion mount.” System, what did you say? You want me to tame the beast-type Evolutionary who killed me in my previous life and make it my mount. Isn’t that a bit inappropriate? “Ding! ‘Random Mission: Obtain a White Lion Mount’ completed.” “Ding! Main mission triggered: Conquer the Apocalypse.” System, what did you say? You’re going to help me conquer the apocalypse!
