Earthlings' Survival Guide [Infinite Flow]

Meteor after meteor crashes into Earth. Beneath their dazzling light comes destruction, and the apocalypse arrives without warning. Amid the devastation, every survivor hears a clear, pleasant voice in their ear: "The Earth Rescue App is now online. Players, complete your missions and protect your home, Earth!" The male lead is always surrounded by hordes of lackeys and swarms of beauties. Unfortunately, Rong Tong has no leadership aura, so he can only roam the apocalypse alone. That is, until one day, he knocks someone silly... Top: Huh? Who am I? Bottom: That's right, you're my sidekick! P.S. A bottom whose chuunibyou phase has gone on so long he's practically asking to get skinned alive, versus a top whose brain gets knocked silly and is tricked into joining him in his antics.
