A Mortal's Record of Cultivating Immortality in Another World

Reborn in another world as a sacrifice to the Mountain God, Xu Fan is about to become food for this eerie being when he unexpectedly obtains a heaven-defying spatial treasure. With time flowing ten times faster inside, he begins growing spirit herbs.

A cultivator guesses that Xu Fan possesses a priceless treasure, but Xu Fan kills him and obtains the basics of Qi Refining, setting him on the path of cultivation.

Using his modern chemistry knowledge, he develops grafting techniques and pesticides, earning the favor of the sect's higher-ups and rising from servant to outer disciple.

Only then does he truly encounter the strange yet fascinating otherworld.

Rebirth + mortal cultivation + eerie demonic beasts + all kinds of Five Elements spells + slow burn.
