This Earthling Is a Sneaky One, Yet He Crushes All the Worlds

[Feel-good power fantasy + no System + cosmic-scale world] The world undergoes a cataclysm, and spiritual qi revival begins. Su Qingche meets his mixed-race campus crush in person after dating her online, then books a room and steps onto the path of cultivation, speeding along from the start. While everyone else is still practicing ancient martial arts, he ascends the Immortal Platform in his mortal body and masters divine abilities and wondrous arts in no time. A powerful expert cultivates alongside him, and the spiritual qi of heaven and earth is instantly sucked dry, leaving the expert staring in panic. On the day a beast horde lays waste to a city, he descends like a god and slaughters the monsters until rivers of blood flow. When the geniuses of the universe's many races arrive in force, he raises Earth's banner and leaves them rolling heads. His name is Su Qingche. He never holds a grudge, because anyone who bears him ill will gets... taken out!
