I'm Already at Level 9999, Why Can't I Get Out of Class?

Social animal Lin Xiaofan transforms into the final BOSS "Abyss Demon King" in the online game "God's Domain" and is bound to the [Performance Assessment System] - he must be killed by players at least three times a week, otherwise he will die. In order to survive, he studied player strategies every day, took the initiative to cut armor, cooperated with diving, and even changed the world-destroying ultimate move into a fireworks show. During a rehearsal, his foot slipped, and he rolled into the sealed forbidden area. He sat down and hid the BOSS "Ancient Dragon Emperor", triggering a server-wide announcement, and his level skyrocketed to 9999. From then on, all the heroes hit him were Miss, and he couldn't get off work at all. The mobs under him went on strike to demand benefits, and the Brave Guild asked him to cooperate in performing a "killed stage play" to cheat official rewards. The operations team worked on patches overnight. Lin Xiaofan finally took advantage of a loophole to lower his level, but mistakenly extended his "novice protection period" for a hundred years, causing the entire server to panic. And his greatest wish has always been so simple and heartbreaking: Who will kill me once?
