Immortality? Sorry, I Only Know How to Kill People

Guan Lin, a five-element useless spirit root servant at the bottom of the Qinglan Sect, was bullied and had no hope of everlasting life. Until the bloody blade of the exterminating evil cultivator hung on his neck. Remaining life span: 81 years, 4 months and 12 days - the price is clearly stated, so you can be honest! Three years of life, in exchange for the peak power of Qi refining, gray hair appears, and he can fight against powerful enemies! Five days of longevity? Exchange life-saving charms, save people from ruins, and survive in danger! Five years of longevity! He changed his body to the threshold of Foundation Establishment, with his white hair stained with blood, and beat down the Foundation Establishment Demon, just to hold on to a glimmer of life in the sea of ​​​​blood and corpses! What is burned is life, what is exchanged is a bright moment! When the ancestor's golden light broke out and turned the tide, Guan Lin, with a body covered in blood, gray and withered, with "great damage to his origin", was unexpectedly promoted to a cabinet disciple because of his "loyalty, bravery and heroism"! Resource? Status? At your fingertips! But the ancestor's warning sounded like thunder: "If you overdraw your source, you will destroy your path!" Only Guan Lin himself knows Becoming a cabinet disciple is just stepping into a more dangerous whirlpool. Suspicion among fellow students, competition for resources, and dangers... Every desperate situation means making a deal with the God of Death. While the entire world of cultivation is struggling for immortality, Guan Lin holds the "Prodigal" system and repeatedly jumps on the edge of madness in squandering life in exchange for power. "Immortality? Sorry, that thing is too luxurious!" I only know how to survive!
