Solo Leveling, Vol. 1 by Chu gong

THE WEAKEST HUNTER OF ALL MANKIND! E-rank hunter Jinwoo Sung has no money, no talent, and no prospects to speak of-and apparently, no luck, either! When he enters a hidden double dungeon one fateful day, he s abandoned by his party and left to die at the hands of some of the most horrific monsters he s ever encountered. But just before the last, fatal blow PING! [Congratulations on becoming a Player.]
