Guo Zilu was drinking, and Cao Xuanxuan came to see Guo Zilu with He Chuner.Because he didn't like Cao Xuanxuan, Guo Zilu had a cold expression, but Cao Xuanxuan didn't care and sent He Chuner and Guo Zilu's servants out.He wanted to discuss with Guo Zilu how to find clues, but Guo Zilu claimed that he had caught the person who cursed his father that day. Cao Xuanxuan certainly did not believe that a curse could kill people, but Guo Zilu insisted. Cao Xuanxuan knew that Guo Zilu did not want to find out the murderer at all, so she said moreTo no avail, he decided to investigate by himself. After coming out, he was going to take He Chun'er to the woodshed to find the cursed girl, Ruohui, but Ruohui had already run away.

He Chun'er checked the injuries on Mr. Guo's body. The fatal injury was only on the waist, which was caused by a dagger. Cao Xuanxuan was confused because Er Niang was poisoned to death, but Mr. Guo was injured by a dagger. The causes of death of the two were different.The clues were also confusing, so Cao Xuanxuan decided to go to Mr. Guan's room to check for clues and called Sun Weiyan over.Cao Xuanxuan also suspected that Mr. Guo was the same as the previous cases. According to the measurement of secret room murder, it was an assassination.

Du Juan and Zhang Yuan secretly agreed on a location and advised each other to leave quickly, because Cao Xuanxuan had already started investigating the case, and Du Juan was afraid of being found out.Zhang Yuan comforted Du Juan that nothing would happen. After sending Du Juan away, he took the initiative to find Cao Xuanxuan and took all the responsibilities on himself. However, all the reasons he gave were not believed by others, and he could not tell the poison.Where he came from, Cao Xuan knew that Zhang Yuan was taking the blame, but Zhang Yuan refused to say anything.

Cao Xuan asked the housekeeper who the two ladies had enmity with in the house, and learned that Du Juan and Guo Zilu had met each other and had a grudge. Cao Xuanxuan concluded that Zhang Yuan must have taken the blame for Du Juan, but in order not to alert the snake, she asked the housekeeperDon't expose it yet.Du Juan had been worried about the death of his second wife, so he hurriedly found Guo Zilu, but was caught by Cao Xuanxuan, and also got the poison in Du Juan's room. Guo Zilu saw that the community had been exposed, so he took the initiative to distance himself from the relationship.Du Juan left directly, but Du Juan explained to Cao Xuanxuan that Zhang Yuan had nothing to do with the case. He did not poison the second lady. He asked Zhang Yuan to buy the poison, but he did not poison him. He did not know why the second lady was poisoned.poison.Why did Guo Zilu come in at this moment? He didn't give Du Juan a chance to explain, and insisted on putting Du Juan into prison and directly executing him.

Cao Xuanxuan felt that something was fishy, ​​so she did not rush to deal with it. She just pressed the person up first, and then took the medicine to the pharmacy where she bought it to inquire. The owner of the pharmacy told Cao Xuanxuan that the medicine she bought had not been used.When Ruohui was eating, she heard that Mr. Guo was really dead. She thought it was the magic that Zhang Daxian taught her that was efficacious, so she went to find Zhang Daxian. However, because Guo Jia died two people at once, Ruohui thought it was a mistake.After Zhang Daxian heard about it, he used it to extort money from Ruohui.Sun Weiyan and He Chun found Ruohui and brought them back to the Guo Mansion together. They also found the poison Cao Xuanxuan was looking for.

Cao Xuanxuan deduced the real cause of Er Niang's death by analyzing the scene that night. In fact, the poison was poured into the well that night. Because of its high density, the poison would sink to the bottom. As the head of the family, Er Niang would definitely be the last one to be poured wine.Naturally, it was the poison that Er Niang drank.Du Juan and Zhang Yuan were also kicked out of Guo Mansion.Ruohui was brought to Cao Xuanxuan, and Ruohui would really hate Mr. Guo.It turns out that Ruohui's father and Mr. Guo were good friends when they met the bandits together. Ruohui's father gave up the chance of escape to Mr. Guo and the housekeeper because of his inconvenience. However, no matter how he explained it, Ruohui was still Mr. Guo.'s fault.Mr. Cao learned that there was a magic stick behind Ruohui, Zhang Daxian, and wanted to find out what the connection was between Zhang Daxian and Mr. Guo. He used a trick of play hard to get, deliberately letting Ruohui leave, and gave him a lot of money.money.
