I'm Invincible at Cultivating Immortality with Mathematical Laws

Modern mathematician Lin Yi accidentally transmigrates into the Xuanlü Realm, where he discovers that the "Heavenly Dao" of this cultivation world is no perfect truth, but an outdated rule System that makes mistakes, monopolizes knowledge, and erases heretics. Starting out as a lowly survivor condemned to have a ruined spiritual root, he gradually uses mathematics to prove the laws of cultivation. Together with Mu Xingyao and three business partners, he breaks the sects' monopoly on knowledge and ultimately rewrites the Heavenly Dao's underlying rules.
