Lu Xingzhou, a down-and-out Lu family disciple at the fourth layer of Qi Refining, accidentally digs out an incomplete, rusted cauldron and discovers it can restore medicinal pills and even waste pills completely back to spiritual grass raw materials. Relying on this heaven-defying secret treasure, he masters alchemy at an extremely low cost, breaks through obstacles all the way from a border town market, vowing to lead the declining family—which has thin spiritual Qi and scarce resources—to counterattack and rise in the cultivation world where strong men stand like trees, stepping on the journey to the peak of the immortal clan.
