How did Bao Zheng discover that Ruoshui was the murderer in Young Bao Qingtian 3? How did Ruoshui die?

If water is the guardian of Tianmang, Bao Zheng and others have come to take Tianmang, and the boss and others were killed by Ruoshui because they discovered the secret of Tianmang ... Just because Bao Zheng insisted on finding Tianmang, he killed Ruoshui. When she solved the mystery of Bao Zheng, she asked him if he was thirsty. She took out a plum from her treasure bag and asked him if he wanted to eat it. Bao Zheng said sadly that he was not thirsty. Ruoshui smiled, as if she couldn't think of Brother Bao every time. She ate it all by herself. It is poison. Finally, she stood in front of gossip and said that she was going to do her own thing. Switch to Bao Zheng. He sat, but blood dripped from his head. Looking back, if the water vomited blood in his arms, he finally died in his arms.

As for how to find out that Ruoshui is the murderer, the key is to break Ruoshui's alibi. Bao Zheng said that she actually built a general temple out of paper, and burned it with torch paper after killing the dead, so the door was inserted from the inside, and I didn't see anyone open the door and run out. This situation gives people the illusion of killing people at close range. If water really kills people from a distance with a bow and arrow, ordinary people will always ignore the strong bow she can pull because she is a woman.
