Tingyulou's gold medal killer blade holds a meteorite black sword in his hand. He has used the sword forty-nine times in ten years. The order of the building is like a mountain, collecting money and asking for life. He abides by the iron law of killers, regardless of right and wrong, regardless of grievances. He allows the black knife to drink all the blood in the world, and the blade is always dull. In the past, he was just a killing weapon that followed orders and had no ego.
A secret order sent him to Dali to assassinate the censor Zhongcheng Zhang Shi'an. Stepping into the city of Taihe, the mist and rain on the mountains, the fireworks on the Erhai Lake, and the peaceful appearance of the people in the city tore through the illusion of his past cognition. He witnessed loyal officials sacrificing their lives to serve the country, glimpsed the treasonous collusion within Lin'an and Dali, and learned that the Mongolian mediator plan was about to sweep across the southwest, and the mountains and rivers of Song Dynasty and Dali were already hanging on a knife's edge.
The stabbing knife was hanging in the air, but he couldn't drop it after all. The mind-asking Gu enters the meridians and distinguishes the good and evil in people's hearts; the natal Gu is connected with each other to share the joys and sorrows of life and death. The former killer saw the suffering in the world beyond the sword. He tore up the rules of Tingyulou, disobeyed the order to kill the rebels, and worked side by side with Duan Shuihui, Ayue, and Yingqi to snatch the leaked defense plans, cut off the enemy's food routes, and guard the Longshou Pass defense line.
Since then, the black sword has changed its direction. It is no longer unsheathed for gold and silver rewards, but only to protect the people and the country. On the one hand, there is the pursuit and suppression of the old master, on the other hand, there are the open guns and secret arrows of the traitors. The huge conspiracy behind the scenes in Lin'an slowly emerges. The old blood feud of the entire Zhang family is closely intertwined with this crisis of the family and the country.
The sword can kill enemies and bandits; it can also guard mountains and rivers. When the sleeping silver pattern on the black knife lights up again, the blade abandons its destiny as a killer and uses its lone blade to block the flames of the beacon fire under the Cangshan Mountain, guarding this side of the Yanhuoshan River with its flesh and blood.
