If Not for Immortality, Why Cultivate Immortality?

Wanshou Xuanmo Sect, Shouyuan Slaughterhouse. The higher the talent, the faster you die. From the moment they are branded with the longevity seal, all disciples are just consumables for the senior management to extend their lives. The great calamity is approaching, and the longevity of all living beings in heaven and earth will become the fuel for the longevity of the old heaven. Su Xuan traveled through time, and as soon as he opened his eyes, he was about to be drained of his lifespan and become the most useless consumable. Fortunately, he brings with him a seed of heaven that does not belong to this world: Life expectancy will be automatically increased by 1 year every day, with no upper limit and the way of heaven cannot be checked. If you die, you can go back in time and keep all your memories and cultivation. Shouyuan can be exchanged for all magical powers without any sequelae As a result, the entire Demon Sect gained an inconspicuous waste. Others fought hard for one year of life, but he slept hard every day, and his life span automatically exceeded 10,000. While others struggled to become a genius, he deliberately failed the test for fear of being regarded as high-quality consumables. Others were harvested by the sect on a monthly basis, so he secretly sneaked into the longevity hall and harvested the longevity of the elders for thousands of years. The deacon wanted to use him as a mine slave, so he trapped the deacon into the fatal mine tunnel. The elder wanted to use him as a medicine cauldron, so he refined the elder into a longevity pill. The sect leader wanted to sacrifice him to heaven, so he directly lifted the Holy Fire Cliff and broke the sect's harvesting platform. Until that day, the old heaven sent down the punishment of annihilation to erase this variable that should not exist. Su Xuan raised his head and looked at the sky filled with thunder and calamity, with a sneer on his lips. "If you don't want to live forever, why should you cultivate to become an immortal?" "Since you want to harvest all sentient beings, then I will do it for you!"
