After inexplicably getting a System and being forcibly bound to it,
the protagonist embarks on a ridiculous life of "selling himself." Not only does he work for free, he also gets saddled with all kinds of dangerous missions.
Protagonist: I'm still a minor! Buddy, you're employing child labor!!! You'll go to jail for this!
System: ? Child labor? When have you ever been paid? If it's voluntary, it's not illegal.
Protagonist: ...
Protagonist: What the hell... f*ck!
So far, the planned worlds are: The King's Avatar, Grandmaster of Demonic Cultivation, Global Examination, and Scum Villain (more will be added later).
[The order is undecided]
Theme: The hard life of an agent
Personally, I feel that the content in it is a bit nonsense, and there is no desire to read it. Of course, this is just a personal feeling, don't mind.
