Memories of past confrontations and frozen feelings emerged before their eyes, and the once sharp conflicts slowly melted away. Shedding his hostility, Hong Hai Er understood the deep protection hidden by his father, and Niu Mo Wang also saw the pure sincerity at the bottom of the youth's heart. Half a lifetime of entanglement, a single morning of reconciliation. Mountains and rivers are vast, the years are gentle. This is a healing myth belonging to an immortal and demonic father and son, telling a redemption story of a defiant youth and a deep fatherly love, healing each other and growing together in both directions.
