After transmigrating into the world of immortal cultivation, Ling Tian awakens a portable space where one year in the outside world equals a hundred years inside. With a space that accelerates time a hundredfold, Ling Tian fills his fields with ninth-grade divine herbs, yet all he wants is to live an ordinary life. While others fight tooth and nail over a single pill, Ling Tian stir-fries thousand-year-old spirit herbs like ordinary radishes. While others desperately search for long-lost magical plants, Ling Tian pulls them out of his garden like weeds. Accompanied by his loyal dog, Wangcai, he travels through the mortal world, hoping to keep a low profile until the end of time. But everything changes when he accidentally enters an ancient tomb and solves an advanced mathematics problem written on its wall, shattering the established conventions of the immortal cultivation world.
