Shen Zhao is the strangest killer in Linjiang City.
Others kill people based on price, but he kills people based on cause and effect.
If the target has young children, he will not kill him; if the target has elderly parents with no one to take care of him, he will not kill him; if the employer is using a knife to harm others, he will in turn investigate the employer.
Everyone in the world said that he had many rules and would not live long. But many years have passed, and those people who did not follow the rules have died, but Shen Zhao is still alive.
Until one day, he received a commission: to kill a wealthy businessman.
The wealthy businessman is full of evil, but he is also the father of two children. Shen Zhao originally wanted to stop, but after investigation, he found that what this family really needed might not be a father, but a belated relief.
The sword can kill people, and it can also cut off evil.
But Shen Zhao knew that the real difficulty was never the killing, but who would live on behalf of the innocent people after the killing.
