In this world that is similar but different from ours, China's ancient brewing techniques hide an amazing secret - a specific group of koji bacteria can store, read and transfer human memories.
Xiang Xing, a talented sommelier with a wine drop-shaped birthmark on his right wrist, took over the family winery after his father's mysterious death, but was accidentally involved in a series of smiling suicide cases. When she accidentally tastes a drop of mysterious wine and falls into a strange memory that is not her own, secrets that have been dusted for thousands of years begin to surface.
The emergence of ancient wine culture scholar Murong Chen is both an opportunity and a crisis. He approached Xiang Xing with the mission of the codebreaker family, but fell into an emotional whirlpool as they got along day and night. When he must choose between his family's thousand-year-old wish and his true feelings, the line between betrayal and redemption becomes blurred.
Police officer Chen Cheng of the Special Investigation Team intervened in the investigation with the obsession of finding the truth about his wife's death. From hostility to trust, from suspicion to protection, this tough guy who lost his index finger gradually uncovered the dark corner of the "Summer Solstice Project" in his confrontation and cooperation with Xiang Xing.
As the "Memory Bank" plan of Huanyu Group CEO Feng Xi is launched, Xiang Xing discovers that his mother's death, his father's research, and the "container body" ability awakened in his body all point to a larger conspiracy - someone is trying to control human memory and reshape reality.
In the thousand-year feud between the guardians and the codebreakers, in the tug-of-war between scientific ambition and ethical bottom line, Xiang Xing must learn to control his own abilities, unlock the ultimate code of Agarwood Ruji, and prevent the memory crisis from sweeping the world.
Purpose: To explore the relationship between memory and identity, the integration of tradition and modernity, and the choice of human nature in the face of technological alienation.
