Briefly about I Became The King by Scavenging manga:
Good news: it has been discovered that your occupation is a concealed one.
Bad news: your hidden occupation is one in ten thousand: ‘Trash.’ You’re about to change careers to ‘Scavenger.’ When Ye Qing saw the results, he felt a white flash before his eyes; all of his years of hard work had been for naught. Borrowing money at high interest rates to invest on stocks and losing everything, creditors forced him into a private hunting group to pay off his debts in the dark. Ye Qing was able to level up from 0 to 1 after conquering an impossible-to-kill Demonic Beast, leading to his single job change chance. But, surprisingly, he awoke to the world’s one in ten thousand clandestine profession—”scavenger.” All of the talent trees revolve on the strange profession of “picking up trash.”
