On the carriage back, An Ying shook his drowsy head and said, "My head wants to blow up." ”

Mrs. Shen smiled and said, "You are young, but you are not afraid. ”

"Where. I always feel that there is something wrong with this, and I can't remember. An Ying couldn't help but beat his head with his hand.

Mrs. Shen hurriedly grabbed her and said, "Hey, don't smash your head." This is not to be done. ”

The carriage soon arrived at the entrance of Dipu Street, and An Ying entered the courtyard in a daze, only to see a man standing in the courtyard with his hands behind his back, looking at a few lotus plants raised in the water tank in the yard.

When the person turned around, An Ying reacted and said confusedly: "Why did Master Su arrive home earlier than me?" This? ”

Su Huangzhe said with a smile: "I came directly from the back street of Yuanwailang's mansion, which is much faster than you and Mrs. Shen taking a carriage from Qianmen Street. ”

"Then why did Lord Su come to me?" An Ying was a little confused.

"Just now in the house of that foreign man, I felt that you were right, I thought so at the time, and I always felt that there was a reason." Su Huangzhe smiled and shook his head, "But the rest of the Criminal Prison Division thinks the same as Guo Langzhong. ”

At this time, Yayu came out and saw An Ying saluting and said, "Miss An, this adult said that he came to you for something important. I decided to stay. I set up tables and chairs in the back yard, and if it is inconvenient, I can go to the back yard to talk. ”

Su Huangzhe said with a smile: "This girl of yours is clever. Then he followed the rain through the hall.

"That Guo Langzhong makes sense. But there is one point, it is not easy to poison fifty catties of tea cakes. Even if you use these tea cakes that are half poisoned, is it more likely that Concubine Su will die of poisoning? An Ying took a sip of the sweet tea brought by Ya Yu and said, "I still want to ask about the poison again." I see that Mrs. Shen and they are very nervous, is this poison very special? ”

"This poison is famous." Su Huangzhe said slowly, took a sip of sweet tea, and stirred the bottom of the bowl with the silver spoon of apricot leaves.

"Famous? How come I've never heard of it? I still have some research on medicinal materials, and I originally thought that I would have money to open a medicinal herb shop and a bead shop, so I deliberately read books for a few years, and I also studied seriously with the pharmacists of Chongdetang. An Ying was a little strange, "That's because the drug was ordered to be removed from the pharmacopoeia." Su Huangzhe said: "This poison was developed by the famous doctor Cai Xiaoting during the Yongkang period. When Yongkang was three years old, Xie used this medicine to poison three imperial heirs, shocking the government and the opposition. Emperor Zhaode burned this poison recipe, and no classics were allowed to record it. ”

"I see. So I don't know, and Mrs. Shen and Mrs. Yuanwailang were so surprised when they suddenly heard about it. Hey, by the way, what does this poison look like? How did this poison get into that tea, and how did this poison be judged, that is, a faint almond flavor? An Ying asked.

"No one knows how this poison was placed. The people who were involved in the poison were killed, the people who participated in the judgment of the case were killed, and the missing people disappeared. The old prison department happened to be a student of the Criminal Prison Department during the Xie case, and it was the first case he had brought to the Criminal Prison Division, so he still remembered the symptoms of this poison back then. I checked the dossier, and the poison was placed in the milk snacks used by several imperial heirs every day, and it was the almond smell that allowed the current saint to escape the catastrophe. The Holy One happens to dislike almonds. Su Huangzhe said in a low voice

"It's not strange that there is an almond flavor in the milk confectionery, but it is very strange that there is an almond flavor in the tea cake. Could it be that the palace maid and eunuch in the tea room don't know that tea cakes can't smell? "Anying is very strange.

Su Huangzhe tapped his head with his fingers, looked at the little girl, and said, "Eh, it seems that I didn't make it clear." The prison temple put the tea cake on the fire and roasted it slowly, so that the faint almond flavor overflowed. On weekdays, it is the normal tea fragrance, and there is no smell at all. Listen to the prison temple said, this poison is extremely difficult to find, the temperature of roasted tea should not be too high or too low, if it is too high, the tea fragrance will come out violently, and the almond flavor will soon be suppressed. If it is too low, it will not emit toxicity at all, and there will be no trace of taste. ”

Hearing this, An Ying fell into deep thought, Su Huangzhe raised his head from the sweet tea bowl without hearing the sound for a long time, and waited for An Ying to continue, but he didn't expect An Ying to just sit quietly, looking at the tea bowl in a daze.

The two sat quietly in the garden, and it was already dark. Yayu came over to ask about dinner, and An Ying came back to her senses and said, "I see that I've been thinking about things, and I'm distracted." Why don't you have dinner together? ”

Su Huangzhe knocked on the tea bowl with his hand, smiled and said, "This sweet tea is authentic, and the craftsmanship is good." How about trying again? ”

When the rain subsided, An Ying said to Su Huangzhe: "I probably know how to poison it." ”

Su Huangzhe nodded knowingly and motioned for her to continue.

"At first, I thought that if I just sprinkled poison on the tea cakes, how could I make it tasteless on weekdays and only have a taste when baking? I always thought that this poison was colorless and odorless, and then when I heated it, it gave off a smell. But how do you poison tea cakes? If the poison is watery, then the tea cake will inevitably be damp, and the tribute tea will be discarded at all. If it is powdery, the tea cake is contaminated with foreign matter, which is also easy to distinguish. Later, when you talked about baking, the almond flavor appeared, and I thought that only when the tea leaves were baked in the mold, adding this poison completely solved all the problems. ”

"Roasting in the mold?" Su Huangzhe suddenly said: "It makes sense, poisoning at this time, as long as the amount is accurately mastered, the problems you mentioned earlier can be solved." I didn't think about it when I was making tea before, because I thought that there were so many tea households involved, and it was too difficult to poison it uniformly. ”

"Actually, you don't need a tea household to poison it." An Ying looked up and said.

"Oh? You were silent just now because you thought that it might be your father's poison? Now you have thought of how to solve this problem? Su Huangzhe picked up the new tea soup and took a sip gently, but in the smoke of the tea soup, his handsome face was serious.

An Ying shook his head and said, "It's hard to make sense that the tea households want to be poisoned uniformly. But there is one thing that can unify the tea households. ”

"Mold." Su Huangzhe reacted suddenly.

"Yes. It's the mold. If the poison is in the mold, all the problems have a reasonable explanation. Why are all the small phoenix groups poisonous, if it is to please Concubine Su, it is okay for the big phoenix group to be poisoned. Why are 50 catties of tea cakes poisonous, there are three tea households involved, and if there are hundreds of people involved in tea making, how to unify these people to poison? Why is the amount of poison so light, and why the tea cake can disperse the poison after being tasteless and baked on weekdays, it is precisely because of this poisoning method. ”

Thinking of this, An Ying hurriedly shouted, "Uncle Zhou, Uncle Zhou!" ”

Uncle Zhou ran out of the kitchen in a panic and said, "Miss, what's wrong." ”

"Uncle Zhou, where is the mold of the little phoenix group?"

Uncle Zhou wondered: "It's in the firewood room behind us, and I always carry it with me." ”

"Where did you get that mold from?" Su Huangzhe asked.

"The mold is from Mindi. Oh yes, I remembered. When the old man came back that day, he brought back a bag of molds, saying that it was brought by Zheng Ping, the manager of the tea shop, and the old man Zheng. ”

Su Huangzhe got up and walked outside the courtyard, and some people from the government came to the door at some point, An Ying hurriedly followed Su Huangzhe together. Su Huangzhe said to Xiao Yi on the side as he walked: "Xiao Yi, give her a horse and let her follow." You take a team of people to escort Zheng Ping to the prison of the Criminal Department, and tell Chen Dong to take people to the capital government. ”
