In a corner of the prosperous Canglan City, there is an ancient book shop called "Buyuzhai". The owner, Lin Jingzhe, seems to be a weak and weak young man who has no power to restrain himself. He spends his days with old books and making tea.
However, when night falls, when the city's neon lights cover up the stars, he has another identity - the uncrowned king of the underground world, the sole master of the "Night" organization. He makes the rules and controls life and death. He is a legend that all dark forces respect and fear.
He is used to "hibernating" in the light and "waking up" in the darkness, enjoying the tranquility and excitement of this double-sided life.
Until that day, a mysterious woman named Su Wanqing walked into his bookstore. She comes from another world of martial arts that is above the secular world, with a probing gaze, like a ray of unexpected sunshine, trying to illuminate the shadow he deliberately maintained.
When a bigger storm swept across the sea, and when the dormant dragon could no longer sleep peacefully, Lin Jingzhe knew that his peaceful days were over.
This time the spring thunder suddenly sounded and the dragon raised its head.
