Shanggu Taishou Geng Fan returned to Beijing to report on his work, which coincided with the illness of Dali Temple, Wang Mang issued an edict in the name of Emperor Ping of Han, and appointed him to temporarily act as the Dali Temple.

Geng Xiaofan's Jing presided over the investigation of his son's murder, and Wang Mang breathed a sigh of relief, he believed that Geng Xiaofan would not let him, or let Wang Jingyan down.

Geng Xiaofan really didn't disappoint the two of them. On the first day of entering Dali Temple, he personally inspected the scene and re-examined Wang Yu's body.

The next day, Wang Mang received a "notice" from Geng Xiaofan, asking him to bring Wang Yu's body back and bury it properly.

Wang Mang was a little incredible, could it be that Geng Xiaofan found out the facts of the case so quickly? He personally rushed to Dali Temple.

Geng Xiaofan was not surprised by Wang Mang's presence at all, but was waiting for him.

"Anhan Gong's Day mourns and changes! Yu'er suffered a disaster, which is distressing. Let's not let him be at peace anymore, let him be buried as soon as possible. Geng Xiaofan politely received Wang Mang.

"Have you checked it all?" Wang Mang was concerned about the cause of his son's death.

"Come with me!" Geng Xiaofan took him to the morgue.

It was a scorching summer, and although the morgue had piled up a lot of ice, Wang Yu's body had already begun to decompose.

"Can you bear to let him lie here again, turned into a pile of rotten bones?" Geng Xiaofan pointed to Wang Yu's corpse.

After his son's death, Wang Mang once came to see him, and it had been more than ten days, he didn't expect his son's body to decompose so quickly, and he couldn't help crying.

"The cause of his death is clear, arsenic poisoning." Geng Xiaofan said calmly, and when he saw Wang Mang's thoughts about "things", he was secretly sad, and led him to the physical evidence room next to him.

"The murderer is very cunning, but it is certain that there are people close to Yu'er, at least people he trusts very much." Geng Xiaofan said, picked up a bronze wine jug, and handed it to Wang Mang, "I don't know if you've seen this jug." ”

Wang Mang took a closer look, only to see that the copper kettle had a round belly and a narrow mouth, and it was well-made, and the body of the pot was carved with a pattern that resembled a dragon and tiger. Although there is no gilt and no gemstones, the texture is solid, giving people an indescribable sense of "heaviness".

It should be said that this is a good copper kettle, but the shape and material are relatively common, which is not unusual for Wang Mang.

Geng Xiaofan saw Wang Mang carefully and knew that he must have never seen this pot, so he explained, "This pot was designed by Mrs. Zun herself, and it was cast by Yu'er herself, just look at the bottom of the pot." ”

Wang Mang flipped the body of the pot, and a stopper-like lid made a crisp "clang" sound, and then Wang Mang discovered the uniqueness of this pot. In general, a flask is without a lid, and this jug is designed with a clever lid, or rather a stopper.

The cork shook twice, but it didn't fall. Geng Xiaofan stepped forward, rotated slightly, and removed the pot stopper lightly.

Wang Mang found that the stopper was also very unique, with a small bulge at the bottom, which matched with a groove in the spout, like a "lock" locked on the spout. The stopper can only be removed by rotating to the groove.

This design is very common on modern teapots and wine jugs, but it was still very "advanced" in the Han Dynasty. It's normal that Wang Mang hasn't seen it.

Wang Mang quickly understood the design of the stopper, and didn't say anything, raised the copper kettle to check the bottom of the pot, and there was a delicate "Yu" character on it. Needless to say, this is the work of the son.

"You figured out how the poison got here?" Wang Mang doesn't care about the pot, he cares about the case.

"Look here." Geng Xiaofan handed the kettle stopper to Wang Mang and pointed to the inside of the kettle stopper.

The inside of the pot stopper is a deep groove, and Wang Mang can vaguely see some white marks. was about to touch it with his hand, but was stopped by Geng Xiaofan.

"That's arsenic, do you want to taste it?"

"Ahh Wang Mang was so frightened that his hands trembled and he almost threw the kettle stopper.

"The murderer was cunning, he mixed arsenic with water into a paste and stuck it inside the stopper. When the carriage was bumping, the solidified arsenic fell into the flask, and the wine turned into poison. ”

Geng Xiaofan explained, and picked up a small pottery dish from the table next to him, which contained some white powder. "This is what remains of the cork, and I scraped it off myself. Experienced, it's arsenic. ”

"This woman is so vicious! So thoughtful! Wang Mang's hands trembled with hatred.

"You mean Wei Wan!" Geng Xiaofan took the copper kettle in Wang Mang's hand, carefully put it away, and took Wang Mang to wash his hands in the copper basin.

"Who else but her?"

"She is indeed the most suspected, but the available evidence does not prove that she is the murderer. There is also a question of motivation, why did she kill her husband? Geng Xiaofan asked rhetorically.

"It's not at the behest of the Wei family! She came to our house to control Yu'er! ”

"That's a reason. But a couple of anomalies. First of all, she has been married into the Wang family for two years, and she has already had a child with Yu'er. People often say that a husband and wife have a hundred days of grace, and there is no deep hatred or necessity, who will do such a rebellious thing? ”

Secondly, although Yu'er had an accident, she left home immediately. But that's my biggest doubt. According to common sense, she committed the crime very skillfully, and even Dali Temple didn't suspect her, why was she in a hurry to escape? Isn't this obviously telling everyone that she is a thief? ”

"Besides, I heard that she left home alone, not even a one-year-old child. Can there be such a ruthless mother in the world? ”

Geng Xiaofan said three reasons in a row, which made Wang Mang hesitate.

"Let's go! Let's take Yu'er home and talk about it! Geng Xiaofan patted Wang Mang on the shoulder and led him out of the morgue.

The two arranged for their entourage to return Wang Yu's body to the palace.

The palace suddenly mourned in unison, and after crying bitterly, Wang Jingyan opened up the funeral for her son and began to decorate the mourning hall.

After Geng Xiaofan's ceremonial worship, he began his own survey work.

First of all, it must be the kitchen. Geng Xiaofan carefully investigated inside and out, and questioned the people present that day one by one. The most crucial person is, of course, the guy who takes care of the drinks.

The little guy is not very old, fifteen or sixteen years old, and he has been "tortured" many times these days, and when he saw Geng Xiaofan asking, he couldn't help but get nervous again.

"They beat you?" Geng Xiaofan saw that there were still scars on the little girl's face, so he couldn't help but step forward and stroke it gently.

The little guy subconsciously dodged, and kowtowed resignedly.

"Get up! I won't be hard for you, I just want to ask you a few words. Geng Xiaofan saw that he was still a child, and couldn't help but feel a little distressed, and personally stepped forward to help him up.

The little guy was still a little trembling, and Geng Xiaofan pulled him to sit down on the threshold of the wine cellar.

"Master, you ......" The little guy was a little flattered and nervous.

"I also have a wine cellar at home, and the person in charge of the warehouse is about your age, but he is not as good as you, and you are cleaner and tidy here. Another day, I'll have to let him learn from you. His name is Dog, what's your name? ”

Geng Xiaofan started from homely cooking, first relieving the tension of the little guy.
