In the early years of the Republic of China, a young man named Lu Zhan, who was looking for his missing father, broke into Shanghai and was accidentally involved in the trial of the Daomen. From then on, he embarked on the road of protecting the treasures of China, carrying the same heavy burden as his father. The Wu Ding bronze jug, the Yaobian Tianmu lamp, the Dunhuang treasure... the treasures that carry Chinese civilization have become the targets of foreigners one by one, and there are also international brokers, comprador organizations, illegal businessmen, and warlord forces involved in reselling national treasures. Even within the Daomen, there are undercurrents and constant disputes. Before Lu Zhan arrived, the predecessors of the Daomen were almost wiped out in pursuit of the twelve zodiac animal heads. The trial of the Daomen is actually the birth of a new "Eight Generals of the Daomen" to pass on the way of protecting treasures.
