During the Qingli period of the Northern Song Dynasty, Lu Mingyuan, the son of a tea merchant, was involved in a murderous situation for throwing in a dragon jade, and embarked on a treasure hunt with Shen Qingli, the daughter of an escort. From the development of the medicinal solution to the resonance of the bronze, the two discovered that the jade was actually the golden key to the royal family of the Southern Tang Dynasty. When Shen Qingli's silver hairpin and Master Huiming's bell tongue combined into a "double key", and the moment the Caishiji Stone Chamber was opened, what awaited them was not only gold and jade, but also the obsession of Sun Huan, the third leader of the Cao Gang, to protect it with his life - it turned out that this batch of hidden gold was the last "national memorial sacrifice" before the fall of the Southern Tang Dynasty. Faced with the choice between wealth and history, Lu and Shen finally returned the jade to the Yangtze River, taking only half of the remaining book with them. Three years later, the signboard of "Jin Bizhai" was raised in Bianliang, Tokyo, and those legends about the Dragon Throwing Sacrifice finally became a past event among the fish and fire in Jiang Feng.
