In the Imperial City Division, Zhao Bai has been living in the small courtyard behind the Imperial City Division since he took over the investigation of the case of the mastermind behind the palace.

In addition to going to martial arts school during this period, Ning Fu also spent most of his time at Zhao Bai's place.

The two went through the various documents in the palace again, looking for possible clues.

What happened at the imperial mausoleum proves that there is indeed a mastermind in the palace who has been targeting the Zhao royal family for hundreds of years.

Renzong had no children, and many princes and princesses of Zhenzong and Shenzong died in infancy, all related to this mastermind.

"The information about the old palace maid Zhou Xiu's entry into the palace is very concise, without any flaws. Even the people who handled her entry into the palace are no longer alive, so there is no way to check it."

After Ning Fu read the information in his hand, he couldn't help shaking his head and sighing.

"The same goes for the information about Qian Jing. It is said that the palace rarely recruits adult chamberlains into the palace, so if we investigate further about Qian Jing's entry into the palace, we should be able to find some clues. Unfortunately, like Zhou Xiu, none of the people who handled it at the beginning were

Alive."

Zhao Bai also looked helpless. Time can erase everything. No matter how detailed the records in the palace are, they are not as clear as interrogating the person involved in person.

"Zhou Xiu and Qian Jing have been guarding the imperial mausoleum all year round, so there is at least one of their people in the palace. It was this person who was responsible for Concubine Liu being poisoned before!"

Ning Fu affirmed again, but it was too difficult to find out this person.

"The palace has also been interrogating, but there are so many suspects that nothing can be asked at all."

Zhao Bai also had a headache when he said this.

"If it really doesn't work, then there is only one way."

Ning Fu pondered for a moment before speaking.

"What can I do?"

Zhao Bai hurriedly asked.

"Kick all these suspicious people out of the palace to prevent the princes and princesses in the palace from being in danger again."

"this……"

Zhao Bai was also shocked when he heard this. You must know that Liu Guifei's route involved hundreds of people. If so many palace people were driven out of the palace, there might be a shortage of manpower in the palace.

"But this is only treating the symptoms rather than the root cause. The masterminds behind the scenes are always one step ahead of us. They obviously have eyes and ears everywhere, so even if the people who poisoned the palace are driven out of the palace, there may still be people from them in the palace."

Zhao Bai finally analyzed calmly.

"I also know that this is treating the symptoms rather than the root cause, but the other party is completely hidden in the dark. Now we can only use this method to reduce the opponent's power."

Ning Fu also said helplessly.

Although the method of driving people out of the palace on a large scale is stupid, the mastermind behind the scenes is well-organized and must be very careful in training people. Therefore, if the other party's people can be driven out of the palace, it will be difficult for the other party to train replacements in a short time.

Zhao Bai also understood what Ning Fu meant. After he thought for a moment again, he finally nodded and said, "Okay, I will suggest it to the emperor, but I am not sure whether the emperor will agree."

"Guan Jia is a decisive person, I believe he will definitely agree!"

Ning Fu knew Zhao Xu's character very well, so he came up with such a method.

"Also, I have another idea."

Ning Fu lowered his voice when he said this, and said again in front of Zhao Bai.

"The mastermind poisoned Concubine Liu before, but they didn't succeed. Do you think that if Concubine Liu gave birth successfully and gave birth to a prince, how would the mastermind react?"

"If I were the other party, I would definitely not be willing to give in. After all, the emperor's brother has difficulty in having heirs. He has been married for many years and has no heirs. He only had children in the past two years, so they are likely to take action against the newly born prince."

The more Zhao Bai analyzed, the more excited he became.

"That's right, if they can drive the people they directly attacked out of the palace this time, there will definitely be fewer people behind the scenes who have access to the prince. If they really take action, the flaws exposed will be even greater!"

Ning Fu didn't want to use Zhao Xu's son as bait, but the man behind the scenes would definitely not let Zhao Xu's son go, so they could only wait now.

"This is a way, but it is not too passive, and it also takes great risks."

Zhao Bai frowned, he was worried that Zhao Xu would not agree.

"There is no other way. The other party is like a rat hiding underground. Unless they come out and move around on their own, it is impossible for us to catch them!"

Ning Fu said helplessly again, if there were criminal investigation methods in later generations, there would be no need for these. The murderer could be found by just checking fingerprints or the like.

Zhao Bai also knew that Ning Fu was telling the truth. The man behind the scenes was lurking too deep. If the other party didn't expose himself, there would be nothing they could do. They couldn't replace everyone in the palace, right?

"Okay, let's go to Brother Huang together, and I will personally explain the situation to Brother Huang."

Zhao Bai finally nodded.

After returning from the imperial mausoleum, Zhao Bai has been unwilling to search for various information. At the same time, he used Tong Guan to interrogate the suspects in the palace, but still found nothing, which made him realize the reality.

So Zhao Yi and Ning Fu came to Chui Gong Hall and reported the investigation in detail.

"Ning Fu, there's nothing you can do?"

After hearing this, Zhao Xu couldn't help but frown, and then asked Ning Fu.

He has always valued Ning Fu's ability very much, and even Ning Fu can think of solutions to many things that he thinks are unsolvable, but he didn't expect that he would be stumped by this matter.

"I've reported it to the officials, but I really don't have any good solutions to this matter."

It would be better to report truthfully.

Compared with the ancients, Ning Fu's greatest advantage was that he was familiar with history. However, there was no record of the man behind the scenes in the palace, which made Ning Fu's greatest advantage useless.

"Brother Imperial, this matter is not due to the incompetence of Ning Fu and I, but to the fact that the mastermind behind the scenes was too hidden, and what happened back then was too long ago, and many people are no longer alive, so there is no way to investigate even if we want to!"

At this time, Zhao Bai cried out for himself and Ning Fu.

"Well, I also know that you have tried your best, but what should I do with Concubine Liu? You can't just passively wait for the other party to make a move, right?"

When Zhao Xu mentioned Concubine Liu Guifei, he felt a little aggrieved, thinking that he, the emperor of a country, could not even protect his own woman and children.

"If the officials are worried about Concubine Liu's safety, I have a suggestion."

Ning Fu stepped forward again and said that since he dared to suggest to Zhao Xu that he should wait for the mastermind behind the scenes to take action, of course he had also considered how to deal with it.

"What advice?"

Zhao Xu asked immediately.

"You can let Concubine Liu use the art of clones!"

Ning Fu smiled slightly.

"What kind of clone technique?"

Zhao Xu was stunned. Concubine Liu Guifei was not a fairy, so how could she know the art of avatars?

"The officials can spread suspicions, seal off several palaces in the palace, and claim that Concubine Liu is raising her baby in the palace, but not tell which palace it is. If it is true or false, it is like Concubine Liu having a baby.
