The eunuch Haitao was the eunuch of the Sili Prison. As early as the current emperor was the prince of the King of Yan, Haitao went to the prince's house, and most of the eunuchs in the palace knew him.

Haitao took the emperor's handwritten imperial edict and entered the door guarded by two eunuchs; Xue Yan, Haitao, and Tan Qing all walked into a room and then saw Concubine Guo.

"Wow..." A sound of iron chain dragging came! When Guo Fei heard someone coming in, she seemed to have taken two steps, and she was wearing shackles on her feet!

Xue Yan didn't expect that Concubine Guo, who gave birth to a prince, would be treated like this! Perhaps, with her identity, she could only end up in such a way if she was involved in murdering the late emperor?

It can be seen that the emperor and those who know the inside story all very much suspect that Concubine Guo is the murderer; she is currently the most suspected person.

Concubine Guo must have met Xue Yan on some occasions. As early as when Wuding Marquis Guo Ying was alive, Xue Yan had a good relationship with the Guo family. Later, Xue Yan served as a matchmaker for the Guo family and helped the Guo family marry the late emperor family, and often went in and out of the Guo family.

"This is hell." Concubine Guo's eyes emerged from her messy hair, staring at Xue Yan alone. It seemed that she did know Xue Yan, and she did not go crazy.

Xue Yan calmed down and bowed and said, "Sei Guan Dali Temple Minister Xue Yan greeted him."

Xue Yan neglected a detail in advance, and suddenly didn't know what to call her. Her husband was already the emperor, but he did not give her a title.

Haitao and Tan Qing also clasped their fists and held their rituals one after another.

"I'm wronged, why do you treat me like this?!" Concubine Guo stared at Xue Yan and said.

Xue Yan said: "If what you said is true, the lower officials are here to clear your grievances."

Concubine Guo suddenly sneered: "Cleaning the wrong? Humph! I understand that from beginning to end, it was a deliberate plot against the stolen matter! They were preparing for it for a long time, how to wash it? Whose person are you?"

After hearing this, Xue Yan thought for a while and replied, "The lower official is the priest. The lower official is the minister of the Dali Temple in the Ming Dynasty. He only asks about the right and wrong of the world, and does not ask about other things."

Concubine Guo said: "They are bold and reckless, and they dare to take action even the emperor's flesh and blood. First, they conspired to cause me to miscarriage! Later, they knew that I was resentful and found evidence. They silenced the palace maid Luoer in the matter, and threatened me, asking me not to consider myself, but to accumulate virtue for the sake of the eyes!

At first I thought they were going to attack Zhan'an again, but I didn't think so... I still underestimated their boldness."

Xue Yan smelled something useful, immediately took out a dense scroll and a brush from his arms, dipped it in his tongue a few times, and started writing.

Seeing this, eunuch Haitao said, "General Tan is watching here, our family asks someone to find Mo for Xue Siqing."

"Who are they?" Xue Yan asked.

Concubine Guo sneered, "Who else can it be? The person sitting on the throne of the queen now and her fellow disciples! Isn't this eunuch around Xue Siqing too? There is also the person called "General Tan" who is from the Tan family? His son Tan Yuan killed someone, who saved his life?"

Haitao and Tan Qing's faces suddenly turned dark.

Xue Yan wrote down calmly and asked again: "You just said that you are determined and prepared for a long time. What does this mean?"

Concubine Guo sat down on a stool, thought for a while, and spoke: "Didn't the imperial doctor say that the late emperor died because he was stabbed by the poisonous needle of the silver ring snake? Before the incident, our Guo family had something to do with the silver ring snake!

At that time, Zhan Yi suffered from convulsions in children, but there was no prescription for the imperial doctor to prescribe a silver ring snake to make wine. Humph! My father happened to meet a pilgrim who was from unknown origin and offered the silver ring snake medicine wine. Then my father sent it to the East Palace.

After soaking in wine, the silver ring snake is of course not poisonous. The imperial doctor also said that it can indeed cure convulsions in children. However, our Guo family has a silver ring snake, and the death of the late emperor is related to the venom of the silver ring snake, how can the Guo family explain it clearly?

I realized it later. It took a few days to wake up. How could it be so coincidental? This was all planned in advance! From the beginning, they wanted to frame the Guo family!

But Xue Siqing thought about it, if I wanted to use the venom of the silver ring snake to murder the late emperor, or Zhan Ji, I must be afraid of being involved in the silver ring snake, so how could I be unprepared?"

It makes sense!

Although Xue Yan didn't say anything, he gently tapped his head. At this time, the inkstone with ink was taken over. He dipped the pen twice and continued to write quickly on the dense scroll.

After asking what Concubine Guo knew, Xue Yan said goodbye.

Concubine Guo was still crying and scolding in the room, and was furious for a while, and felt extremely guilty for thinking that she had harmed the entire Guo family.

After walking out of the yard, the eunuch Haitao immediately said, "Xue Siqing cannot believe her words, she is crazy! The Empress was already the Crown Princess at that time and had the eldest son. How could she take the risk of doing that? What's more, the Empress has always been generous and kind..."

Xue Yan said: "Let's investigate the big case. Even if the empress dowager is unparalleled in the world, I think there are some problems with Concubine Guo's accusations. How did that poison needle be put in the mud?"

Haitao was stunned for a moment.

Xue Yan glanced at Haitao and said, "At present, there are only two ways to put poison needles in the mud: either put them in advance, or Wang Gou'er did it.

If we just assume that this is the command of the queen. First, let it be put in advance; the eldest prince often plays there, isn’t the queen afraid of not hurting the eldest prince? Second, Wang Gou'er is released; then Wang Gou'er should be the queen's confidant."

Haitao hurriedly said, "When the late emperor was still in the Yan Palace, Wang Gou'er was the confidant eunuch around the late emperor. How could it be related to the current Empress? Before the late emperor passed away, Wang Gou'er was in charge of the imperial chef. The late emperor was wise and powerful, so how could he use the Queen's men to manage the imperial chef?"

Xue Yan said calmly: "So, things cannot be easily concluded."

...The group walked out of the palace, out of Chengtian Gate, and to the Wulong Bridge.

At this moment, I suddenly heard the rapid sound of horse hooves, and then a loud "boom" sound of falling down. Xue Yan turned his head and saw a knight falling next to the right gate of Chang'an. The horse fell to the ground and twitched, and the knight was screaming in pain.

When running a horse in the imperial city, a serious urgent matter must be done.

The knight shouted to the defenders at the right gate of Chang'an: "Eight hundred miles in a hurry! Brothers help me, I'm going to Tongzhengsi."

Xue Yan looked around for a while, turned to the people around him and said, "I'm afraid there is news of rebels on the front line."

Haitao and Tan Qing both nodded.

The three of them were in a heavy mood. They silently crossed the Wulong Bridge, then walked to the left gate of Chang'an, went east to the Imperial Hospital. Xue Yan greeted the officials on duty at the Imperial Hospital, and then walked straight into a study room inside and invited the Medical Officer Li he knew to meet.

Xue Yan took out the secret scroll and prepared the cost of the study. When Medical Officer Li came to salute, Xue Yan said nothing more than a word, holding his fists back and saying directly: "Please talk about the venom of the silver ring snake."

Medical Officer Li bowed carefully and said, "The venom of silver ring snake is highly venomous. It is extremely small and invisible to the eyes. It can kill people!

Those who are bitten by the silver ring snake first have symptoms of paralysis, such as drowsy, diffuse pupils, difficulty speaking, or vomiting and nausea; their pulse is weak, and it is difficult to exhale and inhale until they die.

The poisoned person has no cure! He soon fell into a coma and pretended to die. After being bitten by a snake for several hours, he might have died completely."

Xue Yan nodded while writing quickly.

Medical Officer Li continued: "However, although the silver ring snake is poisonous, its life is mostly bitten by living snakes; and the silver ring snake is more docile and will not bite people on its own initiative, so it is not common for the silver ring snake to kill people.

It is because the venom of the silver ring snake is extremely restricted. First, if the oral administration is ineffective, blood must be used to cause poisoning. Second, after the snake venom is taken out of the snake's mouth, the toxicity is extremely easy to decay until it is non-toxic."

The poisoning of the late emperor was caused by poisonous needles, and of course it was not bitten by a living snake. Therefore, Xue Yan asked: "How long can it be stored after taking out the snake mouth?"

Medical Officer Li said: "One day and one night... However, the Imperial Hospital has conducted an experiment. If the silver ring snake venom is taken out of the snake's mouth and stored in ice, it can remain toxic for up to half a month."

Xue Yan nodded slightly, held the pen and thought for a while. Based on Medical Officer Li's description, he made a hypothetical speculation...

There are no silver ring snakes in the capital city. The mastermind must first catch live snakes in Zhili, Zhejiang or other provinces, raise them and try to transport them into the capital city; then take venom outside the imperial city, store ice in the ice cellar, and then try to send them into the palace.

Because the searches for entering and leaving the palace are very strict, it is impossible for a live snake to enter the palace! The amount of venom is small, and by ordinary means, even if the population tries, it will definitely not be found to be venom... So Xue Yan's speculation is that it is more likely to directly transport venom into the palace.

The frozen venom is kept in the palace for fifteen days. If the murderer does not find a chance, he will transport venom from outside to the palace; or he will transport snake venom once every ten days, so that the murderer in the palace can always have venom!

According to many people who witnessed the poisonous needle, the poisonous needle was rusted.

The iron needle rusts, of course, it is not rusted because they are buried beside the pond; snake venom cannot be stored in the mud for so long. There is only one possibility. The iron needle is originally a rust needle; because the rust absorbs water, after soaking in the venom, more venom can be stained on it, making it easier to succeed in the slaughter!

The wet mud that can be made into clay is of course not a thin mud, it should be relatively dry and it is difficult to dilute the venom; so it is impossible to rule out that the poison needle has been put in advance, and it has been a few hours.

Xue Yan now judged that it is possible for the murderer to kill the regicide with the silver ring snake venom!

"It's a blessing for Medical Officer Li." Xue Yan put down his brush and bowed his hands.

Medical Officer Li hurriedly bowed and said, "This is the duty of the lower-ranking officials, and the lower-ranking officials say goodbye."

After saying that, Medical Officer Li glanced at the eunuch of the Silijian and the commander of the Jinyiwei, and left without asking for a second without asking any extra words.
