Lu Zheng was not wrong.

He and the dark guard are extraordinary, although he delayed some efforts to find the dark guard before, but he still went to the Star Picking Tower with Huixin.

Hui Xin ran out of breath, and just arrived at the door of the Star Picking Tower, but saw that Lu Zheng had already arrived, and couldn't help but be startled.

But in the end, he was worried about the safety of His Royal Highness the princess, so he didn't scream.

Lu Zheng didn't appease her, and asked directly: "Are you inside?" ”

Hui Xin nodded busily.

Then, I saw Lu Zheng raise his chin towards her and signal her to go in first.

This move is exactly what Huixin wants, and she is afraid that Lu Zheng and the others will scare the fourth princess if they suddenly enter.

Huixin hurriedly pushed the door open, and then whispered inside: "Your Highness, the slave and maid are back, and the general and the imperial doctor have also arrived." ”

Because the lights outside the Star Picking Tower were dim, Huixin didn't see clearly who the person behind Lu Zheng was, and only thought that it must be the imperial doctor.

Seeing that she misunderstood, Lu Zheng naturally couldn't explain, and the dark guard couldn't explain it even more.

Their identities are not allowed to appear in front of people, and tonight is an exception, but fortunately they change their faces every day, and they do not show their true faces, which is convenient now.

As soon as Hui Xin's words fell, Lu Zheng and the dark guard also entered the Star Picking Tower with her.

When I entered, I saw no one.

The candle flame inside had been extinguished, and it was dark that it was impossible to see which was or whether there was anyone.

Of course, this is only for Hui Xin, for Lu Zheng and the dark guard, this little darkness can't completely block their eyesight.

Soon, Lu Zheng and the secret guard found Du Yiheng and the fourth princess in the corner.

Then, the voice of the fourth princess also came, "Huixin, I'm here." ”

Huixin heard the voice and hurriedly stumbled over.

When I got closer, I found that the fourth princess and Du Yiheng were hiding in the corner, the fourth princess was sitting on the ground with her knees crossed, and Du Yiheng was lying unconscious, covered with the cloak of the fourth princess.

Huixin didn't know what to say, the princess treated Du Gongzi very well.

On such a cold day, Her Royal Highness the princess went down to her cloak, and she didn't wear much inside, and she must have been cold after sitting on the ground for so long.

Huixin hurriedly ran over to help the fourth princess up.

As soon as he touched the hand of the fourth princess, it was really cold, and the person shivered slightly, and he knew that it was frozen at a glance.

Huixin was suddenly very distressed, but in front of Lu Zheng and them, she couldn't say anything, so she had to rub the hands of the fourth princess with her own hands, hoping to pass on her body temperature to the fourth princess.

"Wechen has seen Her Royal Highness the Fourth Princess." At this moment, Lu Zheng and the secret guard also arrived, and the two bowed their hands to the four princesses.

The fourth princess said: "General Lu, don't be polite, this is the imperial doctor brought by General Lu, if so, let's take a look at Du Gongzi first?" ”

That's really the most important thing right now.

Du Yiheng is unconscious, there must be something wrong.

Lu Zheng was also worried about Du Yiheng's safety, so he asked the secret guard to hurry up and take a look for Du Yiheng.

As for the fact that the four princesses and their master and servant misunderstood the identity of the secret guard, he didn't plan to explain it.

So he told them to think that it was the Tai Doctor who came.

The secret guard knew Du Yiheng's identity, so he naturally didn't dare to slack off, and when he got Lu Zheng's order, he immediately squatted down to check for Du Yiheng.

They were all well-trained, and even when they saw Du Yiheng wearing a cloak that didn't belong to him at first glance, they didn't show the slightest surprise.

In the interval between the secret guard's diagnosis and treatment of Du Yiheng, Lu Zheng asked the fourth princess: "Dare to ask Her Royal Highness the princess, can you tell me more carefully about the situation you encountered Du Gongzi." ”

The fourth princess knew that Lu Zheng must have suspected that someone had deliberately harmed Du Yiheng, and she was also trying to tell the truth, not planning to hide it, not for anything else, just for Du Yiheng.

Therefore, the fourth princess told Lu Zheng everything she knew.

In fact, the details are not very important, as long as Lu Zheng hears the words of Concubine Rong's palace maid, he will immediately understand the cause and effect of the matter.

Sure enough, as soon as Lu Zheng heard the fourth princess say that the person who helped Du Yiheng to go to the tea room in the side hall where the female dependents rested was the palace maid beside Concubine Rong, he understood the secret.

It seems that at the palace banquet, he felt that Xu Ziqian had been watching Concubine Rong intentionally or unintentionally, which was not an illusion, but a reality.

Xu Ziqian must have helped Concubine Rong deliberately trip herself, so that Concubine Rong could find someone to drug Du Yiheng to buy time, and then facilitate the person to take the woman to the tea room where the dependents rested.

The fourth princess and Hui Xin both said that there was a peculiar smell of incense in the tea room, and Lu Zheng couldn't understand what it was.

It's hard to announce her daughter's family, but Lu Zheng understands.

I'm afraid that the incense must not be a good thing, most of it has an aphrodisiac effect.

Concubine Rong asked Du Yiheng to be sent to the tea room lit with aphrodisiac incense, and next, I'm afraid I will arrange a woman to go, right?

Let him think about who she will arrange for to come over?

There are a lot of official ladies who came to the palace banquet today, but there are not many who are the same age as Du Yiheng.

Lu Zheng recalled carefully, checked the past one by one, and soon, he locked the target.

This is not because he remembers those official ladies very clearly, but because among the women who meet the above conditions, only the father of the second daughter of the Xu family, Xu Ziqian, the secretary of the Ministry of Rites, has strange words and deeds, and deliberately pesters him.

Xu Ziqian is the person of the eldest prince, and it is not surprising to help Concubine Rong do this kind of thing.

However, his sacrifice of his daughter is really not the work of a big husband!

Even if Concubine Rong and the Xu family succeed today? is that the girl of the Xu family really married into the Right Prime Minister's Mansion, how could she be treated well by the Du family?

The Du family is benevolent, but they will not have any pity for the son of an enemy who calculates his own children.

He figured all of this out, but what he didn't understand was, when was Du Yiheng drugged?

It's not easy to do anything about the dishes of the palace banquet, is it wine?

Du Yiheng can drink a lot of wine today, and if he takes medicine from it, it is very possible.

Wait, he seems to have overlooked something.

He remembered!

Du Yiheng later drank the sobering soup, and after drinking the sobering soup, people were sleepy, and it was because of this that he asked the inner attendant to help Du Yiheng go to rest first.

The waiter, yes, the waiter!

"Dare to ask Her Royal Highness the princess, have you ever seen the chamberlain beside Du Gongzi?" Lu Zheng asked.

"Chamberlain?" The fourth princess was stunned when she heard this, then shook her head and said, "I didn't see any maids in this palace, I only saw the two palace maids, General Lu asked, but what's wrong with the waiter?" ”

The fourth princess is not stupid, on the contrary, she is also very smart, so when she heard Lu Zheng ask like this, she also realized the problem.

Naturally, the palace maids are indispensable at the palace banquet, and if there is a problem with the servants serving Du Yiheng, then it makes sense that Du Yiheng was plotted against this time.
