My History of Traveling Through Time and Becoming Stronger

I am from Earth, an ordinary college student named Wang Junci. One night, I met a system, but this system is a little different from other systems. Other systems all lead the protagonist to do all kinds of tricks to pick up girls and show off their skills. "As for mine, my head hurts just thinking about it." In this way, Wang Junci started his journey of becoming stronger in various novels and comics worlds because of the system. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
