We all know that Zhang Yi is a good policeman in a police station. He solved many cases, including the water lily case he took over. It is because he took over the case that he has a certain relationship with Karry. In this case, we can see that police officer Zhang is the savior. If police officer Zhang hadn't started from Zhang Yi, he might have gone astray, because many things have happened in this case. Karry is on the side of the murderer. He is independent. He doesn't listen to the police. It is precisely because Zhang Yi's police officer Zhang trusted him and taught him well that he did not go astray. I also told him many things in the middle.
Zhang Yi is the savior of Karry. Whenever wandering between light and darkness, Zhang, a police officer from Zhangye, comes to persuade and tell him the pros and cons of things. Although some of them reprimanded Karry, it was for his own good. Without the help of police officer Zhang, you may go astray. Standing between light and darkness, he may formally stand on the side of darkness. Not only can he find out why his father is the murderer, but he can't. So, we are lucky that Karry met such a good policeman. It was because of Zhang that he finally not only found out the cause of his father's death, but also made him formally move towards the bright side.
Officer Zhang is the savior. It is because of him that we can see him.
