During the Zhanghe period of Dajing, Shen Ye, a traveling doctor on the border, was attacked when he was protecting refugees. He was led to the mysterious Shiguang Inn by the copper pendant left behind by his father. A bowl of soul-forgetting wine brought out the past life bond between him and the plain-clothed woman Su Wan - they were soul-protecting seals in their previous lives, and Su Wan agreed to "pick up the light" to reunite before his soul disappeared.
Chen Jiuzhen, the owner of the inn, revealed that the copper pendant is a fragment of the soul seal, Shen's father is the former head of Xuanhun Sect, and Zhou Yanzhi and Xuanjizi are plotting to seize the soul core and control the remaining soul to destroy the world. Shen Ye, together with Su Wan, Mo Chen and other partners, gathered five soul seal artifacts and used soul seal skills to fight against the villains. With the heart of guardianship across the world, they smashed the conspiracy, protected the peace of the border forever, and revealed the secret of soul seal reincarnation.
