Su Yu knew that something was wrong with him. After reading a detective novel, he realized that when he saw the cruel methods of murder, he could not help but imagine the victim as his father. He could also predict the success rate of the killer's methods and the step that caused the success rate to decrease. In order to verify his prediction of the success rate, he planned an accidental murder. He took into account every factor. In the end, the victim triggered an "accident" and died. Su Yu succeeded.
That day, he saw his father lying in a pool of blood like his mother. The strong smell of blood and the red color in front of him seemed to remind him that blood was a living substance that was hidden in countless tiny blood vessels in the human body. It pierced through all the organs in the body and carried the life of a person. This was also his life.
