In the prosperous age of Tianbao, under the prosperous Tang Dynasty, yin and yang were out of balance and evil spirits were rampant.
Shen Tianqing, a young soul connoisseur, possesses the unparalleled [Yin Yang Eyes]. When he first entered Chang'an, he acted like "pretending to be a pig and eating the tiger" and killed the Yin Sijiao protector with one sword, which made him famous in Beijing. He holds the [Soul-Slaying Knife] in his left hand to slay demons, and the [Heavenly Master's Seal] in his right hand commands ghosts and gods to search for the three lost treasures of the Soul-Suppressing Division in the shadows of the prosperous age.
However, God is fair, and what you gain is what you lose. In order to protect the people and his loved ones, he opened his yin and yang eyes again and again, and paid a heavy price: he lost his sense of taste, faded color, and forgot his memory, until his emotions were dulled and he became a rational machine.
The Anshi Rebellion broke out and the prosperous age collapsed. Shen Tianqing, who has lost his memory, instinctively looks for the "person wearing the silver bell" in troubled times - Liu Qingluo, a saint from the Miao border. She used the fervor of "one heart and one fate" to confront his coldness of "sacrifice alone". When the whole world requires heroes to die alone, they choose to use love as a blade to cut off fate.
From the ghost market in Chang'an to Loulan in the Western Regions, from the bloody battle in Suiyang to the ghost gate of the underworld, the two work together to kill the seven guardians and seven demon generals. After going through three calamities and nine difficulties, they finally persuade the King of Hell with the concept of "symbiosis" and rewrite the underlying logic of the book of life and death.
"Is it worth my thirty-five years to trade for this troubled world?" "As long as you are by my side, every second is worth it."
This is a story about "burning life to protect the one you love", and it is also a heaven-defying journey of using short-term affection to fight against eternal numbness. In the afterglow of the end of the prosperous Tang Dynasty, they proved that the best ending is not to live alone and become a saint, but to live and fly together in the same year, the same month and the same day.
