I Become a God Through Silver Tongue

Modern-day transmigration + sharp-tongued champion System + a爽爽 tale that turns tropes on their heads. Li Bufan, a supreme master of verbal sparring who rails at the heavens, the earth, and even the air, cuts his way through every obstacle. If ghosts block his path, he slays ghosts; if Buddhas block it, he slays Buddhas.

He makes a name for himself in the grand world of immortal cultivation. Li Bufan, oh, Li Bufan, you've really outdone yourself!
