He was once the nine-headed demon king who was stained with blood on the battlefield. When his true body was shattered and his soul was about to disperse, the ancient oath awakened from his bloodline - he was originally the son of the water god in charge of killing and protecting.
He was once the young master of Qingqiu who controlled the world. The moment he sensed the mournful cries of heaven and earth, his dust-covered godhead suddenly opened up - he was originally the nine-tailed celestial fox in charge of fertility and contracts.
And she was Wang Ji and a doctor who thought she had experienced the vicissitudes of life, but in the heartbreaking pain, she glimpsed the source of her bloodline - she was the last mountain ghost to maintain the balance of "life" and "kill" in the world.
When the blood moon shines over the North Sea, the vision of three suns shining together once again casts the fate of the three people. The ancient covenant roars in the blood: they must be a trinity, one cannot exist without the other.
From then on, when they stepped out of the hidden realm of gods, they faced not only the eyeing chaos demons and the suspicion and prying eyes of all forces, but also the conflict between each other's divine powers and the turbulent tug of inner emotions.
But, this is just the beginning. When the sleeping will of chaos awakens from the ruins and vows to return all things to nothingness, they must make a choice: follow the ancient destiny and sacrifice one person in exchange for a seal? Or risk everything to find a never-before-seen "return to origin" road for the three of them?
This is a hand in hand that spans life, death and divinity, an eternal love song composed between divinity and humanity. Mountains and seas are my oath, and this heart will never change.
