반로환동인 줄 알았다
A man who attempted to destroy a 40-year-old prisoner awakens in the body of a 20-something. He believed he had mastered Banrohwandong, but it was actually possession. His internal energy, cultivated over a lifetime, is gone, and his new host is weak, nicknamed "MuMu." Kang Daesan, the lone heir of the Mugeuk School, now young but stripped of his power, must regain his martial arts. Yu Seok, the frail second son of the Changcheon Confucian School, begins a new path.
