Jiang Haotian traveled to a world where humans and monsters coexisted, and became a soldier guarding the border. He thought he would just guard the border for the rest of his life, but he didn't expect that a big demon would pay attention to him. He punched him three times and activated the system. Killing the enemy will gain the remaining life span of the enemy, and consumption of life span will increase the progress.
