High Martial: I Failed the College Entrance Exam, and the System Only Shows Up Now

Jiang Lan is reborn into a high-martial world where people can awaken supernatural abilities. With the memories of his past life, he thought he would be able to thrive. But reality slapped him in the face once again! His mother died when he was three, and his grandparents passed away when he was six! When he was nine, his father came home covered in blood with a girl three years younger than Jiang Lan, entrusted her to him, and then died! At sixteen, Jiang Lan awakened an ordinary ability: [Heart of Passion]. It did nothing but make his heart beat faster and stimulate his body's potential. It had no offensive capabilities whatsoever. Jiang Lan was in tears. He failed the college entrance exam outright. In this world, spiritual qi had revived and monsters ran rampant. Powerful ability users fought on the front lines to repel monster attacks. People like Jiang Lan went straight to factory work after graduation! Luckily, there was still hope. The Lifespan Exchange System had arrived. Spend lifespan to exchange for anything in the System! Jiang Lan wagered 100 years of his life and got an ability upgrade potion! [Heart of Passion] evolved into [Eternal Heart]. Eternal Heart: When the Host kills any living being, they gain life points in return. “Host killed an ant and gained 1 life point.” “Host killed a Tier One monster and gained 10 life points.” “1 life point can be exchanged for one day's lifespan.” When Jiang Lan saw that life points could be converted into lifespan, he let out an excited, cackling laugh! As long as he didn't die, he would eventually become invincible!
