Sixteen years ago, Liu Ruyin, the pregnant wife of the martial arts alliance leader, followed her husband into battle against the demon cult—only to face a fateful upheaval on Soul-Severing Cliff. Facing her own flesh and blood, she ultimately could not bring herself to strike the killing blow, sowing the seeds of future peril. Sixteen years later, the youth bearing the Demon Seed begins to show strange signs, and buried secrets resurface. Liu Ruyin devotes herself to protecting her son, unaware that mother and child have long been bound by an eerie power. As the demon seed awakens, family bonds, obsession, and the struggle between good and evil intertwine—and a crisis spanning two generations quietly unfolds across the martial world.
