Jin Wan, the vice captain of the local criminal police was responsible for assisting with Zhao Yu's investigation. He was about 10 years older than Zhao Yu and looked very vigorous and fierce.
After staying with him for a short while, Zhao Yu found that this man was not at all what he first appeared to be. Instead, he was careful, delicate, and experienced, a police officer who had worked for a long time and had solved many cases.
Currently, it was very early in the morning as Jin Wan turned to to Zhao Yu in the police car and said, "We have four groups of police forces from each branch office to assist you in your investigation. They will all be under your command and at your service at any time. If there is any need beyond that number, we can increase our forces at any time."
