Sihanbu Cheonjaega Saranamneun Beop

Gifted by the heavens yet cursed by fate, Yeonshin was born with unimaginable talent in martial arts. But this very gift condemned him to a life that would end before adulthood. With the right opportunities, he had the potential to become a legendary hero, or the reincarnation of the Heavenly Demon. Yet fate cast him into the third-rate Jeong Clan, a family of no particular renown. Now, with time slipping through his fingers, Yeonshin must find a way to defy his doomed destiny.
