My Teacher Is The Strongest Human

A time-travel system? A super powerful elixir creator system? Or a high efficiency level up system? You can choose between these, but let me warn you about one thing, there's nothing more powerful than my meritocracy system! ... This is a history about a lone man who traveled to another world! (I know, it's kinda generic). Follow the main protagonist (name will be revealed in chapter 1) in his not so ordinary daily life!
