In Chiang Mai, Thailand, where supernatural legends and modern tourism intertwine, Lin Yan, a cultural relic restorer, just wants to live a stable life. An ordinary restoration of ancient artifacts accidentally awakened his past life memory as a disciple of the last mage of the Ayutthaya Dynasty, and bound him to a mysterious "Eye of Contract" system. System prompts can help him avoid danger, but they also drag him step by step into the whirlpool: an ancient village where spirits coexist, the cursed spiritual guardian girl Nalin, and the mysterious organization "Pure World" that claims to "purify the world" but actually seizes the power of thousand-year-old spiritual veins. The leader of the organization was actually his fellow senior who should have died in a coup in his previous life. On one side was the "steady development" warning from the reminder system, and on the other side was the countdown to the imminent collapse of the contract. Lin Yan discovered that the secret of his survival for thousands of years and the truth about the survival of this land were actually entangled in the same misunderstood oath. He must make a choice: follow the lessons and systematic guidance of his previous life to protect himself wisely, or break the thousand-year cycle and find a truly equal path of symbiosis for humans and spirits.
