Song Ruilong put the bowl on the table, waited for a while, and then asked Su Xianrong to try it again with the silver hairpin.

When Su Xianrong put the silver hairpin into that bowl, the tip of the silver hairpin turned black.

Su Xianrong said in surprise: "There is poison in the bowl."

Su Xianrong took out the silver hairpin, wiped off the poison on the silver hairpin with a cloth, inserted the silver hairpin back into his head, looked at Song Ruilong, and said, "Brother Song, what is going on?" Why is it that when we put water in this bowl for the first time, the water is not poisonous, but when we put boiling water in it, the bowl is poisonous? ”

Song Ruilong asked Su Xianrong to look at the water, and Su Xianrong said in surprise: "Where did this oil come from?" What we poured in was water. ”

Song Ruilong asked Su Xianrong to look at the bottom of the bowl, Su Xianrong found that at the bottom of the bowl underwater, there was a hole that was slowly getting bigger, and the last hole was about the size of a sesame seed, and it would no longer get bigger in the future, Su Xianrong said excitedly: "I understand the murderer's killing method." The killer first hollowed out the bottom of the porcelain bowl, leaving only a hole the size of a sesame seed. Through that hole, the murderer can put the poison at the bottom of the bowl, and then he seals the bottom of the bowl with white wax, so that Guo Meiqi will not find anything wrong with the bowl. Even if this bowl poisoned Guo Meiqi, no one else could find out who poisoned it. ”

Song Ruilong nodded and said, "Your analysis is very reasonable. I think we can find out who the murderer is from this pair of mandarin duck porcelain bowls. ”

Su Xianrong said a little strangely: "Do you know who poisoned the bowl?"

Song Ruilong nodded and said, "This method of poisoning is not clever, and the object to be poisoned is not precise, because he doesn't know who will use that poisonous bowl." And that person, that is, the suspect, he chose this method, which shows that he knows the situation of Guo Meiqi's family very well. He made a pair of mandarin duck bowls, the purpose of which was to poison Guo Meiqi and Ding Chaotai. Now Guo Meiqi is dead, and Ding Chaotai is still alive. This shows that the murderer's purpose has not been achieved, and he is likely to kill Ding Chaotai again. ”

Su Xianrong's heart tightened, and said: "There is this possibility, so we must find Ding Chaotai before the murderer, maybe he can help us find the real murderer."

Song Ruilong said: "We only need to think about these two mandarin duck bowls to find out the murderer."

Su Xianrong stared at the big eyes and said, "What do you say?"

Song Ruilong thought for a moment and said: "Think about it, this pair of mandarin duck bowls are hollowed out at the bottom, it is not easy to make such two bowls, but if it is a person who can fire porcelain to make it, it must be easy, therefore, I conclude that these two bowls were not bought by Guo Meiqi on the street, but someone specially gave them to her."

Su Xianrong said: "Brother Song is reasonable. But who gave this bowl? When it was delivered, I'm afraid it's hard to check. ”

Song Ruilong didn't think so, he shook his head lightly, and said, "No, the time when this person delivered the bowl is very easy to calculate." It should have been delivered after lunch yesterday at noon and before dinner was lit. ”

Su Xianrong looked at Song Ruilong in surprise and said, "You are not an immortal, how can you calculate so accurately?"

Song Ruilong smiled and said, "This kind of thing, mortals just need to think about it. You think, if this wax-sealed poison bowl was delivered before lunch, then Guo Meiqi might have used that bowl to serve rice at noon, if she ate it at noon, then she shouldn't have died this morning. Looking at the wax seal in this bowl, we have only scratched it until now, which shows that the poison in the wax seal has not worked. It may be that another bowl worked, so Guo Meiqi was poisoned. Whether or not the person who gave Guo Meiqi the poisoned bowl killed Guo Meiqi, we must find out that person first. ”

Liu Tianxiong and Wei Bixiao wore civilian clothes, asked around, and finally found Ding Chaotai at the home of Ding Chaotai's sister Ding Chunhua.

After Liu Tianxiong sat down in the room where Ding Chaotai lived, he looked at Ding Chaotai with an expressionless face and said, "Ding Chaotai, this mission asks you, when did you arrive home yesterday?"

Wei Bixi felt that this Ding Chaotai was full of flesh and did not look like a good person, so he didn't have a good impression of Ding Chaotai at all.

Wei Bixiao had a calm face and said, "Ding Chaotai, you have to recruit from the truth, otherwise, you know the consequences."

Ding Chaotai looked innocent and said, "The two sent people, I don't know what crime Xiaomin has committed, why do you want to talk to Xiaomin like this?"

Wei Bixiao had already identified Ding Chaotai as the murderer, and she said viciously: "What are you doing with so much nonsense? Now we ask you something, and you answer honestly. If you don't feel comfortable talking here, we can also change places. ”

Ding Chaotai heard the meaning of these words, and knew that he was likely to be involved in a very important case, so his tone of voice softened, and said, "Xiaomin said." Xiaomin is a good citizen, he has never been short of money in business, and he often lends money to his friends. Xiaomin didn't get home until last night, probably after dinner. At home, before Xiaomin entered the house, he heard someone talking in the house, and he was still talking unpleasantly. As soon as Xiaomin heard this, he knew that his wife must be fooling around with other men, so he picked up a stick, kicked the door open, and rushed in. ”

When Xiaomin rushed to Guo Meiqi, she was getting dressed on the bed, and she was still saying, yo, why didn't you come back and tell the slave family? Xiao Min looked at the open window and the footprints on the window, and knew that the adulterer must have fled. Xiaomin chased to the window to take a look, only to see a black back disappear into the night. Xiaomin asked who the adulterer was, but Guo Meiqi didn't say whether he was alive or dead. Xiaomin lit the candle and saw a bowl on the table in the bedroom, and there was a mandarin duck on the bowl, so he broke the bowl with a stick. Guo Meiqi ran out of the bedroom angrily. Xiaomin didn't chase either. ”

Liu Tianxiong's eyes rolled and said, "Then what about after that?" That is, from the time Guo Meiqi left to today's fifth watch, where were you? ”

Ding Chaotai thought for a while and said, "Xiao Min came to Xiao Min's sister's house and slept in this room for a night. If you don't believe me, you can ask Xiaomin's sister. ”

Wei Bixi said: "Master, this murder case is not child's play, Ding Chaotai is Guo Meiqi's husband, he should go back to see his wife." ”

Ding Chaotai was very surprised and said, "Who?" Who do you say is dead? ”

Ding Chaotai didn't seem to know that his wife was dead, and he looked very shocked.
