Game Invasion: Demon Summoner

In the sixth year of the game invasion, the demon race turned reality into hell. Li Mu was not chosen by the system; he was just a 'coordinator' who delivered potions, repaired equipment, and collected corpses for players. His entire family's life depended on him—if he survived for one year, his parents could live in the safe zone forever. On his first day after graduation, he was assigned to a suicide squad of rookies. On their first mission, they encountered a demon mage who shouldn't have appeared in the low-level area. His teammates fled. He lay on the ground, and to survive, he bet his life by drinking the demon mage's blood. When he woke up, a cold mechanical voice sounded in his mind: 'Congratulations on becoming a player. Please open your panel to view your class.'
