Everyone: I Became the Villain Boss

My name is Zhang Yi, and I have traveled to a world where games have come to reality. Monsters are rampant here and there are countless copies. Humans can upgrade by changing jobs and killing monsters. Therefore, I also became an adventurer and received a simple task of finding objects from the NPC. However, what I never expected was that the thing turned out to be in the dragon's cave... ... My name is Caesar, the ultimate boss. He likes to take naps on treasures, kidnap princesses for fun, and spend his days playing tricks on adventurers. The greatest pleasure is watching more and more treasures you conquer. I woke up today and chatted with the breakfast delivered to my door. I unexpectedly discovered that the world actually has mechanisms such as levels, tasks, and explosion rates. I decided to change my profession and not be a boss. After all, who would bother hunting monsters for free when there are extra rewards? Then the world went haywire... Adventurers: "Evil dragon? Is he the boss of this level?" Evil Dragon: "No, no, no, you are the boss, I am the adventurer." This novel and its characters are purely fictitious.
