Liu Mang, an antique dealer with a net worth of over 100 million, woke up to become the down-and-out shopkeeper of Panjiayuan store in a parallel time and space. The fog of travel has not yet cleared, and a blood-stained silk book from the Han Dynasty is quietly delivered to you. Deciphering the text on it, he was shocked to realize that it was a secret record about another time traveler - Wang Mang, pointing to an ancient machine that could transcend time and space.
Go home! The obsession to return to his wife on the sickbed overwhelmed everything else. However, the journey back was buried deep under thousands of years of loess. His family used to be giant thieves who robbed the tombs of princes, and blood and curses have long been part of their bloodline. Now, he must retravel the "ghost path" of his ancestors and go deep into the forgotten dark tombs: the gloomy tomb in the late Eastern Han Dynasty, the secret palace in the troubled times of Cao Wei, the luxurious Quicksand Golden Valley in the Western Jin Dynasty... And even the legendary lost ancient ruins.
Accompanying him are Li Mo, a culturally protected young man who has shouldered the crime of robbing his ancestors' tombs, and Wang Chuang, a rough, cunning and talented Fa Xiao. Behind him, there are more mysterious forces that covet the "secret", and the cold legal network of cultural protection is also quietly tightened. There are many mechanisms, surrounded by strange things, and the greed and protection of people's hearts are intertwined.
When the ultimate secret Wang Mang left behind in the cracks of time and space is revealed, Liu Mang will face the cruelest choice: activate the "Tongtian Jishu" that may destroy everything, and gamble on the slim road home? Or should we cut off our obsessions, carry eternal thoughts and secrets, and stay in this misplaced time and space?
