Xie Yeqing traveled back in time and returned to the Tang Dynasty on the eve of the Anshi Rebellion. He held a fragment of the scroll and knew the secret but had no soldiers or power. He meets Mu Yao, a lonely and arrogant swordsman. This man is responsible for the secret edict of the previous dynasty and hides the world's worries under his cold blade. The two went from distrusting each other to becoming an alliance based on blood. Xie Yeqing used his power to weave a network, and Mu Yao used his killing to open the way, secretly rewriting the mission of Jiedu, overthrowing the powerful minister and blocking Hu Qi's way south. They are not saviors, but they use their flesh and blood to tear apart the collapsed fate of the prosperous Tang Dynasty. When all the dancing is over and the beacon smoke has not yet risen, only they know that the country has been quietly rewritten.
