My Second Self Cultivates All My Skills

Chen Chuan's life hit rock bottom. Fresh out of high school in a class-ridden city, his uncle gave him two months to fend for himself, deeming him too old and untrained for any real future in the coveted martial arts academies. But what no one knew was the phantom twin, his 'second self,' that had appeared with his transmigration. This ghostly doppelganger could absorb all his pain and, when merged, grant him unimaginable strength, speed, and endurance. His first test at the elite Wuyi University was supposed to be a brutal wake-up call, but when a vicious senior attacked, Chen Chuan's 'second self' took the blow, then merged, unleashing a counter-kick that shattered expectations. Now, with a path to power finally open, Chen Chuan must master this bizarre connection, for the very act of overcoming foes strengthens his phantom twin. But who killed his predecessor, and what terrifying secrets does this 'second self' truly hide?
