I Became a Legend After My 10 Year-Long Last Stand. Episode 3

Sorcerer Luck feels his time has finally come. To save his friends, he single-handedly confronts thousands of Djinns (demons). Without sleep, he fights alone for years in a rain of blood, finally defeating their commander. But when he regains consciousness, he discovers that he has spent 10 years in this struggle, and his body has shrunk to the size of a 15-16-year-old hyena. When he meets his old friends (Hero Eric and Warrior Goran), they realize that Luck has long since died and they have made him the greatest hero of all time. Luck no longer wants to get into any trouble and simply wants to live a peaceful, laid-back life. So he changes his name to "Lock" and starts his journey from scratch as a novice adventurer with new friends.
