The immortal king goes against time and space for love, but his lover turns into an old enemy. Thousands of years of reincarnation and cause and effect are chaotic, and I ask about my original intention in front of the Yulin Spring.
Buddha, the Immortal Lord of the Heavenly Realm, returned from all the calamities, and was shocked to realize that he had forgotten a deep-seated love - three lives and three lives ago, he was Ye Dingzhi in the human world, and he was deeply in love with Baili Dongjun, the sword immortal in white. In order to find his lost fate, he violated the rules of heaven and forced his way through the long river of time and space. However, due to the turbulence, he fell into the chaotic world of humans and monsters thousands of years ago.
In this era when demons rule and humans are insignificant, Fo Rong meets young Hong Ye: ragged and scarred, but with unyielding fire burning in his eyes. Even though his face was immature and his memory was completely lost, the Buddha's face was still recognizable at a glance - that was Baili Dongjun's previous life, and he was also the king of demons who would unify the demon world in the future.
At this time, Hongye was just a human boy abandoned by his tribe on the east coast, struggling under the oppression of the demon tribe. Fo Rong conceals his identity and accompanies him, using the secrets of the fairy world to help him practice, vowing to reverse his tragic fate of becoming a demon king and becoming an enemy of the human race. However, the wheel of history is extremely heavy: rumors of the imminent emergence of the Jade Spirit Spring stirred the world, demon tribes are gearing up, secret "awakened ones" among the human race are quietly surging, and the mystery of Hong Ye's life experience involves a taboo past that crosses races.
Fo Rong gradually discovered that his intervention in history was causing shocks in time and space, and the current and past lives of his former lover were tugging at each other in Hong Ye's body. When the Yulin Spring, which symbolizes the "ultimate realization of desire", is truly opened, everyone will face the most cruel test: to choose omnipotent power, or to protect the purest obsession in the heart?
