The small courtyard behind the Imperial City Division was originally Zhao Bai's residence, but now it has been requisitioned by Ning Fu.

There is a black wooden board standing in the living room. There are many names written on the white paper on it. There are lines between the names, and each line has a different label.

Ning Fu took a pen and thought for a moment before highlighting a few names.

What is written on the blackboard are all known clues, mainly the various characters that have emerged, such as the lines of Hu Zhuo and Zhou Quan, and also mixed with a little chamberlain named Huang Ying.

Apart from this line, the most conspicuous line is the other line, that is, Zhai Hong who sent the witchcraft villain to Master Miaojing.

Since Zhai Hong surfaced, Tong Guan also sent people to keep an eye on him quietly.

This Zhai Hong is now working in the palace of Concubine Wu. Concubine Wu is the biological mother of the little princess, who almost died during childbirth.

Originally, the little princess did not live with her mother, but something happened to the little prince before, and Zhao Xu was also worried about her daughter's safety, so he let the little princess live with Concubine Wu.

In other words, as long as Zhai Hong is willing, it is possible to get in touch with the little princess.

After Zhao Xu learned about this situation, he became very nervous and even wanted to arrest Zhai Hong directly.

But they were persuaded by Ning Fu and Tong Guan. After all, the organization behind the scenes was huge. Catching just one Zhai Hong would be of no use at all. Instead, it would make the masterminds vigilant. If they lurked back then, there would be nothing they could do.

Originally, Zhao Xu was unwilling to risk his own children. Even when Zhao Bai proposed it, he directly rejected it.

But the situation is different now. The only son is poisoned and dying, and the brother with whom he has a deep relationship is also dead. The truth cannot even be announced to the outside world. It can only be said that Zhao Bai died of illness. This makes Zhao Xu feel extremely aggrieved.

So in this case, Zhao Xu finally decided to take a risk, and ordered Tong Guan to secretly send someone to keep an eye on Zhai Hong, and at the same time, he also had someone secretly protect the little princess.

Even in order to prevent the news from leaking, even Concubine Wu did not know that there was a danger lurking around her. After all, she was a woman, and if she lost her composure, the mastermind behind the scenes would definitely be aware of it.

The surveillance of Zhai Hong during this period was also quite fruitful, and now there are several more names next to Zhai Hong's name.

Ning Fu stretched out his hand and drew a circle on the name "Wang Hui", and then connected her and Zhai Hong's names together.

Wang Hui was Concubine Wu's personal maid, and according to reports from people monitored by Tong Guan, Zhai Hong and Wang Hui seemed to be very close.

There were even rumors among the palace people that Zhai Hong was pursuing Wang Hui and wanted to marry her.

This method is exactly the same as that used by Hu Zhuo against Shu Yu, so this Wang Hui is probably the key figure targeting the little princess.

Of course, Wang Hui, like Shu Yu, should be just a chess piece of the mastermind behind the scenes, and may be silenced afterwards. Even Zhai Hong is a chess piece that can be discarded at any time.

What Ning Fu is most concerned about now is who is the person behind Zhai Hong?

Originally, Ning Fu and Tong Guan had speculated that the person behind Zhai Hong was probably Zhou Quan, because Zhou Quan not only had a high status in the palace, but was also in the upper echelon of those behind the scenes.

However, during this period of time, Zhai Hong had no contact with Zhou Quan, and even the people around Zhou Quan had no contact with Zhai Hong.

Tong Guan also brought in Zhai Hong's information, but it turned out that the two had no connection whatsoever, which made Ning Fu also begin to suspect that there should be another important figure behind Zhai Hong.

Now Ning Fu is waiting for this figure to surface. If it is really not Zhou Quan, then through him and Zhou Quan, it is possible to find a more important figure.

"Uncle, please have tea!"

Suyin came over with tea at this time.

After Zhao Bai's death, Suyin and Yu'er, as his personal maids, were originally going to plead guilty together. However, Ning Fu used the excuse that they were familiar with the mastermind behind the scenes to ask Zhao Xu to pardon their sins and give them the opportunity to make meritorious deeds.

, now helping Ning Fu organize information from all parties.

"Well, how is the investigation on the relocation of the Cao family going?"

Ning Fu picked up the teacup and took a sip before asking Suyin.

When Ning Fu saw Zhao Bai for the last time, he was investigating three clues about the mastermind behind the scenes. Among them, the clues about Master Miaojing had confirmed that she was indeed quietly communicating with the outside world, but had nothing to do with the mastermind behind the scenes. She just wanted to contact her family.

Get information from the outside world.

As for the other two clues, they were the drug dealer who supplied medicine to the palace, and the sudden relocation of Cao Gui's family, and the Cao family's relocation was assisted by a local wine merchant.

"The news I just sent is that the wine merchant has already hired someone. When the Cao family moved, they were entrusted by a man named Liu Ming, and this Liu Ming is the brother-in-law of Qi Tai, the medicine merchant!"

Suyin replied immediately.

"There is indeed something wrong with Qitai. Is he still in the secret cell now?"

Ning Fu was also shocked when he heard this. Qi Tai, the drug dealer, was one of the clues Zhao Bai investigated. Now the two clues are combined into one, which also confirms that there is something wrong with Qi Tai. Among the medicinal materials he sends to the palace every year

, all have a large number of strychnos, and strychnos is the favorite poison of the mastermind behind the scenes.

"Here, His Highness personally interrogated him, but he was a very hard-boned person. No matter how he was tortured, he just bit him to death. He was just greedy and did not mention his relationship with the mastermind behind the scenes. Now that the evidence is conclusive, he has no choice but to plead not guilty.

.”

Suyin also replied very excitedly.

Since the death of Zhao Bai, Suyin and Yu'er's biggest wish is to avenge Zhao Bai, so the two women have worked very hard during this time and have lost a lot of weight.

"Come on, let's go meet this Qitai. Are his family members still in the capital?"

Ning Fu stood up immediately and asked as he walked.

"Everyone is here. When Qitai was arrested, he was arrested on the basis that the accounts and medicinal materials did not match up. As for his family, His Highness sent people to keep an eye on them and strictly prohibited them from leaving the capital."

Suyin followed Ning Fu to report.

"Very good. Don't alert others for now. Send extra manpower to keep an eye on the Qi family!"

Ning Fu ordered again.

Qi Tai is obviously an important person in the palace who contacts the outside world, so he may have clues about the mastermind behind the scenes.

Ning Fu came to the secret prison quickly, but thinking that the last time he came here, it was because Zhao Bai was here, but now he was alone, which made Ning Fu a little sad.

Then Ning Fu calmed down and ordered Qi Tai to be taken to the interrogation room.

After a while, a bruised Qitai was dragged in. He had lost all appearance. It was obvious that he had suffered a lot during this period.

"Qitai, can you plead guilty?"

Ning Fu asked the others to step back, then looked at them closely and asked.

"The villain pleads guilty. It was me who tampered with the accounts and embezzled funds from the palace!"
