I remember reading it before it is also available on dragon - tea, bad man system:)

Novel is fine it's just uploaded source has issue and 1/3rd of text is repeated.

Its good story unit 150+ it becomes team and I hate female lead she was too much, she has having everything for free because he always exchange things for unequals things, it turn worse after 150+ 5 trains tracks combines and his teammates enjoy everything for free without helping and getting anything also they called japanese and wanted to lend his weapons for his chinese people (what a businessman)

I didn't expect it to shounen-ai, when finding this novel i maked sure there no cp but it's seems it's still escaped from net :((((
