My name is Lu Qingan. Having lived in the cultivation world for over ten thousand years, I awakened an ability to gain lifespan by destroying vitality. Originally living in seclusion and surviving in the mortal realm, I was abducted by immortals to Panlong City in the Immortal Realm. The immortal world treats ascensionists from the lower realms as 'lifespan springs,' implanting gu poison to harvest their lifespans, and has established a lifespan exchange tower to trade lifespan for supreme treasures. I did not take the gu poison pill, secretly and frantically accumulating lifespan instead. I protect my friend Zhen Yongfu, whose fortune defies the heavens, rope in Xu Qingying, who possesses a treasure vase, and maneuver among major forces. Relying on alchemy and reselling treasures to build capital, I exchange for high-tier magical treasures, surviving step by step in the perilous immortal world.
