Wear It Until the Game Opens [Holographic]

Bertha has become the boss of the new dungeon of the holographic game. Because killing her has a 0.1% Chance of dropping a rare appearance, you can imagine the fate of being abused in the future. It will be some time before we leave the server. Bertha: Let's go out and level up first! She traveled around the world, became brothers with the Demon King of the Abyss, chatted and laughed with the Elf King, stole the holy sword of the human prince, tricked the mermaid priest into landing, released the imprisoned evil dragon, and lured the angel into darkness. And they are all the big bosses of the highest level dungeon in the game. The game server was launched, and the players were all shocked when they saw Bertha with a health bar of 999999, a blue bar of 999999, and a level??? Is this a fucking newbie boss? Intention:1
