When the Ultimate Dungeon's Final Boss Becomes a Player

Yu Xian has been the final boss of the survival game's ultimate instance for 10,086 years. In all that time, only one person has ever cleared every game and become one of the game's administrators.

Since Yu Xian has only seen a single player make it to the final stage in all the time she has been conscious, one of the game administrators proposed scrapping that stage and making the earlier levels easier, so that more players could take part in the final round of selection.

If the ultimate instance is scrapped, its game boss will be sent to other game instances to serve as an NPC.

Although Yu Xian has no idea how she became a game boss, she can't stand the lofty airs of those game administrators. How can they ruin her laid-back life of 10,086 years with a single word? If her game instance is scrapped, won't that mean a demotion and a job in someone else's instance? It's hard to go from luxury to austerity, and she won't let them destroy her game instance! She'll prove with her own strength that the humans selected to take part in the game are simply incompetent. They can't lower the game's difficulty just to cater to lowly creatures! That would only ruin the entire survival game's ecosystem!

To save her instance, Yu Xian enters the game as a player.
