Xiaoshi Village was massacred by mysterious immortal cultivators overnight. Young Su Twelve was burdened with 234 lives and worshiped the Yunge Sect with the mysterious pill furnace left by his grandfather. As the worst miscellaneous spiritual root, he was assigned to the waste elixir room, but unexpectedly discovered that the alchemy furnace could temper waste elixirs and improve magic weapons. From then on, he relied on prudence and resourcefulness to rise step by step amidst the competition among the immortal sects and the trials of life and death. At the same time, he secretly investigated the real culprit who destroyed the village, and embarked on a path of cultivating immortals that defied heaven and aspired to the top.
