its about a physics introvert student isekai'd into a Cultivation world where everyone practices doa.

but still physics formulas are very powerful and mysterious in that cultivation world because already 10000 years ago

a earthling already reincarnated in that world and made cultivation teachings by psychics formulas.. after he gone..

everyone forgets about this techniques because it's hard to learn for them except One mysterious powerful Sect those who followed 1st reincarnated person..

after 2nd guy isekai'd he find out psychics teachings are very powerful and by saying Pressure Formula P=F/A Everyone around him felt immerse aura pressure..

by saying Speed Formula S = d/t he can Move like light.

but since he's an introvert and reserved everyone thinks he's soo mysterious and powerful but nobody can feel any cultivation power within him because in reality he can't even Cultivate anything in that cultivation world except relay on earth psychics formulas of earth.
