Poyang King Xiao Fan confronted Wang Li, and Wang Li insisted that Xiao Fan kidnapped his nephew to threaten him to poison the imperial chickens.

Xiao Fan promised that afterwards, even if Wang Li committed suicide to keep it secret, he would give his brother a lot of money and allow his father and son to spend the rest of his life in peace.

Other details that Xiao Fan questioned, such as when the two met, Wang Li said one by one, and the time when they met was indeed Xiao Fan in the palace.

As for the poison used for poisoning, Wang Li said that it was a small bottle given by Xiao Fan, and the bottle contained poison like water.

The way to poison is to use Wang Li to apply the poison to the thumb of his right hand before testing the poison. When testing the poison, after drinking the sweet soup, he held the bowl's right hand and quietly put his thumb into the bowl to make the poison into the soup.

In this way, Wang Li is fine, but the emperor will die of poison after eating sweet soup.

As for the poison bottle, after applying poison to the thumb today, it was crushed without leaving any trace.

This method of poisoning made the Queen Mother and the ministers feel cold on their backs after hearing this: Indeed, if someone else doesn’t pay attention to it and doesn’t see Wang Li’s little movements on his thumb, he will not notice that the sweet soup has been poisoned.

When Xiao Fan heard this, he stopped entangling with Wang Li. He had the consent of the empress dowager and asked the prince of Nan County Xiao Dalian, and asked the other party how he "heard the wind" and judged that someone was going to poison today?

Seeing Xiao Fan struggling desperately, Xiao Dalian tried to pull him into the water and admitted frankly: He had bribed the eunuch in the palace before.

Foreign ministers colluded with eunuchs, and even if they were just asking for information from the palace, they would have committed a big taboo.

Xiao Dalian knew that he would suffer certain consequences after his spies were exposed in the palace, but he didn't care as long as he could defeat Xiao Fan, a traitor with ulterior motives.

"Wang Li has been distracted all the time, and it seems that he has something to do in his heart. I remembered that my brother was harmed by others in the palace before..." Xiao Dalian's voice was a little choked when he said this.

He did not answer Xiao Fan, but made a statement to the Empress Dowager.

"I don't want to give you a chance to do evil in the palace anymore, so I know that I have violated the ban, but I still bribed several palace ladies and asked them to be more careful on weekdays. Once they find something wrong, they will inform you immediately."

"I learned that Wang Li seemed to be inappropriate, so I secretly observed his family. He had a brother and a nephew."

"As expected, his nephew has not seen each other for many days, and something seems to have happened."

"Wang Li was an eunuch and tested the poison for the imperial meals on a daily basis. The empress thought about it and felt uneasy, so..."

"I am making friends with eunuchs and peeping into the ban. I am willing to be punished. Please follow the law to punish the crime! And instruct the eunuchs who poison and act as a traitor, the queen mother! I will definitely punish him with the right principles!"

The Empress Dowager looked at Prince Nan and looked at King Poyang again: "King Poyang, what else do you have to say?"

Xiao Fan replied: "I think that Wang Li said that even if this method succeeds, it will be extremely toxic and will not kill the dog."

"He chose to poison sweet soup, because the poison must be bitter or has a strange smell. If the poison is added to other dishes, it is likely to be exposed because of the strange taste, so it needs to be covered with sweet taste, then it must be..."

"Weichen, I have figured out a way to prove my innocence."

Xiao Fan said slowly, his originally frowning brows relaxed: "I ask the Queen Mother to allow it. I ordered someone to take something from the mansion to prove my innocence."

The Poyang Palace has been surrounded, and the Empress Dowager has just confirmed it.

It was of great importance, so she decided to figure out the poisoning matter and look at the important officials. Seeing that everyone agreed, she allowed Xiao Fan to summon a follower and return to the palace to get an item.

Of course, you must have the imperial guards to accompany you so that the followers can travel smoothly.

It took time to go back and forth. At Xiao Fan's request, the Empress Dowager asked someone to prepare nine bowls of sugar water.

When Xiao Dalian saw him, he felt strange: What do you want to do?

But he was sure that Xiao Fan could not escape this time because the poisoner Wang Li had already proved that Xiao Fan was the mastermind.

Unless there is clear evidence to prove that this identification is a lie, it will be useless to let Xiao Fan defend himself.

You should know that last year, the rescued Princess Xiangdong accused the princess of Xiangdong's concubine of the mastermind, and the reason was that when he was imprisoned, he heard that the thief was wrong and mentioned a person.

The man was Wang Xun, the concubine of King Xiangdong. At that time, the Wang brothers and sisters were unable to defend themselves and went to the company to surrender and wait for the deceased.

If it weren't for the real murderer who caught the real murderer afterwards and confirmed that the "slip error" that the Princess Xiangdong heard was deliberately done by the thief, then the Wang brother and sister would have been finished long ago.

He was thinking, but he heard Xiao Fan say, "If you want sweet soup, you have to use sugar."

Xiao Dalian thought this was nonsense, so Xiao Fan continued: "How many kinds of sugar are: honey, malt sugar, oyster sugar, sucrose, etc."

Next to him, Wang Bao looked at Xiao Fan, feeling complicated. He really hoped that Xiao Fan was not the mastermind of poisoning, but if Xiao Fan was not the real murderer, who would be the real murderer?

If the real murderer can be found as soon as possible, it would be fine. If it cannot be found, things will be in trouble.

Just imagine, if someone can poison the food and food in the palace at any time but cannot find it out, then will the Empress Dowager and the Emperor dare to live in the palace?

If you move out of the palace and go back to the East Palace to live, what is this? If you don’t move out, the emperor has a few shortcomings, so what should you do?

Wang Bao was confused, but he heard Xiao Fan continue: "If you use these sugars in the diet, it is not impossible to distinguish them, but it is very difficult."

"For example, malt sugar and sucrose have similar sweetness. It is extremely difficult to distinguish them by tasting and eating."

"But, Weichen has a way to distinguish it in a simple and straightforward way, at least, he can distinguish sucrose and other sugars."

When the empress dowager heard this, she looked at the bowls of sugar water that had been arranged and felt inexplicably.

Xiao Dalian also felt inexplicable, but he believed that Xiao Fan could not prove his innocence, so he wanted to see how the other party wanted to make a judgment.

After a while, the entourage had already taken back the items that Xiao Fan wanted, but it was handed over to Xiao Fan by someone else, to prevent the entourage from secretly sending news to Xiao Fan.

After inspection by the guards, the item was found to be a small jar containing blue liquid.

Xiao Fan asked the Queen Mother: "The things in the jar are color-producing potions. The ones I received by me will scoop a spoon each and put them in each bowl of sugar water, which will dye the sugar water blue."

"After a while, the color turns dark red, and the sugar water is made of malt sugar or honey."

"If it is still blue, this sugar water is sucrose water."

"In other words, using the stuff in the jar, you can distinguish whether the sugar water is sucrose water, which is a color development method."

The empress dowager looked at the ministers and saw that no one had any objections, so she asked an eunuch to conduct "experiment" according to Xiao Fan's request.

After pouring some blue liquid into the nine bowls, the originally basically colorless sugar water turns into light blue.

After a while, the six bowls of sugar water changed from light blue to light red. Although the color was light, it could still be seen as red.

The other three bowls of sugar water are still light blue.

In advance, Xiao Fan asked the Empress Dowager to order people to prepare three bowls of malt sugar water, three bowls of sugar water made of honey, and three bowls of sugar water. They used bowls of the same pattern, without any markings, and arranged after the order was disrupted.

Now, the Queen Mother ordered people to pick up the sugar water and turn it into a light red bowl, look at the bottom of the bowl, and sure enough, these six bowls contain sugar water made from malt sugar water and honey.

The three bowls of sugar water that have not turned red are all sucrose water.

Xiao Fan asked again to "develop" the bowl of toxic sweet soup to see if the color will turn from blue (dyed by color-developing potion) to brick red.

As physical evidence, the sweet soup has been proven to be poisonous. The Empress Dowager agreed to Xiao Fan's request and asked the eunuch to scoop a spoonful of "color-producing potion" into the bowl.

After a while, the color of the sweet soup did not change.

At the same time, the bowl of sweet soup was prepared at the same time, and another bowl of sweet soup that was used for use was also brought over.

The Queen Mother could confirm that the few bowls of sweet soup had not moved after the incident, and it was covered with it, and no one came into contact with it directly.

Now I started to test the poison. The dog used to test the poison took some sweet soup. After waiting for a while, there was no sign of poisoning.

Then, the sweet soup was "experimented" and the blue color-making potion was added, and it slowly turned into a light red.

The results of the experiment surprised the empress dowager and several ministers: In other words, the sweet soup the emperor ate was tampered with and replaced!

Xiao Fan said: "It is obvious that the bowl of sweet soup that Your Majesty is about to eat is probably not only poison, but also sugar."

"However, I have asked carefully just now and confirmed that when the sweet soup used by Your Majesty is made, the last one is malt sugar."

It's a bit confusing, but it's easy to figure it out.

I tried poison before leaving the imperial kitchen, and it was fine.

The meal was brought to the emperor, and there was a person supervising the whole process, and there was a lid covering the food and soup. There was no possibility of replacement or poisoning.

After the incident, the Empress Dowager repeatedly verified this point and confirmed it correctly.

The sweet soup should be non-toxic when it comes to the poison test eunuch Wang Li.

Even if you dip your thumb into the venom and then put your thumb into the bowl while holding it to poison it, it is impossible to turn the malt sugar in the sweet soup into sugar.

So the question is: When did the non-toxic sweet soup in the bowl (sweetened with malt sugar) become a toxic sweet soup that is sweetened with sucrose?

"This is impossible..." The empress dowager blurted out. She thought carefully that when the incident happened, it was impossible for anyone to replace the sweet soup with the entire bowl.

It is impossible for someone to replace the sweet soup in the bowl.

Because when Prince Nan said that the diet was poisonous, she ordered people to keep an eye on all the food, pastries, and soup, and no one was allowed to approach it easily.

According to the current "test results", the thief must have replaced all the sweet soup in the bowl, but how did the other party poison it later?

She looked at Wang Li. The poisoning method mentioned by the other party had been overturned by the experiment of King Poyang, so it can be seen that this person was lying.

Wang Li couldn't hold his head down, his body trembled like a sieve, and Xiao Fan said again:

"I can probably guess how the traitor should poison it, but there is no evidence, so I specially brought this color-producing potion."

"Sure enough, Weichen's guess is right. The problem of sweet soup is not ordinary. So, next, another experiment may be explained."

After Xiao Fan finished speaking, he asked for another bowl of backed sweet soup to be tested.

An eunuch grabbed a handful of sugar in his hand and put it into a bowl.

Sucrose is a granular solid that quickly melts into the soup, and there is no clue.

After that, I conducted another experiment. This bowl of sweet soup was added with color-making potion, and it did not turn red after it was dyed blue.

Xiao Fan expressed his opinion: "Sugar will melt quickly when it is put into water. If the amount is used too much, it will cover up the sweetness of malt sugar, so it can cause the color-producing potion to fail. Now it seems that Wei Chen's idea is correct."
