Since she bumped into Su Yue'er's villain, Su's mother has taken more strict care of Su Yue'er, and she will not let any outsiders see Su Yue'er.

In case Su Yue'er shouted that she was going to kill the prince, she didn't know what the consequences would be.

But this news can't be hidden from Qin Boyong.

Every day, someone will quietly pass on Su Yue'er's daily trace behavior, according to the spies in the prefect's mansion, Su Yue'er's madness is getting worse day by day, except for her parents, she almost doesn't know anyone else, and sometimes she laughs inexplicably, sometimes she cries inexplicably, everyone else who looks like this is very scared, of course, the most she does every day is to sit in one place and keep cursing Qin Boyong.

Lu Yuan followed Qin Boyong's side, and after learning about Su Yue'er's current situation, he was a little suspicious of her state.

"Isn't she going crazy?"

Lu Yuan frowned, "I don't think it's right. ”

Qin Boyong raised his head slightly and asked, "Do you think she is pretending to be crazy and stupid?" But what good can it do her? ”

Lu Yuan shook his head, "I don't know, it's just that I've known Su Yue'er for so long, and with what I know about her, I won't be crazy like this just because you beat her up." ”

His fingers gently groped his chin, revealing a thoughtful look, "I'm afraid it's a bit of a problem." ”

Qin Boyong smiled, "Anyway, now you can free your hands from Gu Muzhi, if you are really suspicious, then find a time to go to the Su family, just say that I am thinking of Su Yue'er's body, you can go and treat her." ”

Lu Yuan came back to his senses, bowed to Qin Boyong, and laughed teasingly: "The prince sacrificed his reputation for his subordinates, and his subordinates are very grateful. ”

The smile on Qin Boyong's face stopped abruptly, and then he raised his head and glared at Lu Yuan.

Lu Yuan laughed twice and retreated from the study.

The next day, Lu Yuan visited the prefect with a medicine box on his back.

The prefect looked at Lu Yuan, who had a sincere face in front of him, and was a little embarrassed for a while.

In fact, he had seen Lu Yuan a few times and knew that he was a very important person beside the prince, so for the prince to send him to Su Yue'er for treatment, the prefect couldn't help but have a subtle hope in his heart.

But on the other hand, he didn't want Lu Yuan to see the current Su Yue'er.

Because, her madness is really a bit powerful, if cursing the prince is heard by Lu Yuan, what if Qin Boyong comes to find trouble again? After thinking about it, he still stopped Lu Yuan.

"Mr. Lu, Yue'er's current state is really not suitable for seeing outsiders, I know that you and the prince are kind, but I'm afraid that she will hurt Mr."

Lu Yuan said lightly: "Don't worry, I'm the doctor." ”

"Yue'er, she can't describe it now, I'm mainly afraid."

"It's fine." Lu Yuan's tone was calm but unquestionable, "Doesn't the prefect believe in my medical skills?" Or do you not believe in the prince? ”

"It's-"

The prefect choked suddenly, and finally had to nod helplessly, and said in a pleading tone: "Then trouble Mr. Lu, it's just that Yue'er has serious hysteria, don't take what she said to heart." ”

Lu Yuan nodded, "That's nature, I'm a doctor." ”

A few minutes later, under the introduction of the prefect, Lu Yuan finally met Su Yue'er.

But even if he had already known Su Yue'er's recent situation before, the moment he saw her, Lu Yuan couldn't help but be surprised.

Her hair was scattered, her eyes were blue and black, and her eyes were blank, even if someone came, she was like she couldn't see it, she just squatted on the ground and kept sticking to the floor with a branch, and kept muttering in her mouth, listening carefully, she could hear Qin Boyong's name.

An hour later, Lu Yuan returned to the palace.

"Is it pretended?"

Qin Boyong asked.

Lu Yuan's face was a little unsightly, and just when Qin Boyong thought that Su Yue'er really had a problem, he shook his head and said in a deep voice: "Lord Wang, Su Yue'er was drugged. Although she did suffer a little bit of a blow herself, it was mainly the drugs that caused her mental problems. ”

At this time, Qin Boyong's face was also a little solemn.

"Could it be that there are other women in the backyard framing her? Or is there a spy? ”

Lu Yuan said: "I'm afraid it's the latter." ”

Qin Boyong nodded, and then ordered the secret guards to start secretly investigating the people Su Yue'er had come into contact with during this time, as well as those who might have drugged her food.

The most important thing is that the **** used by Su Yue'er is very likely to be given to her by that person.

In order not to startle the snake, the secret guard did not find the target until the third day, and finally locked on a target after excluding some old people in the courtyard and miscellaneous servants who did not have the opportunity to do anything to Su Yue'er's diet.

It was a middle-aged man who only entered the mansion half a month ago, this man has been helping in the kitchen of the mansion since he entered the mansion, and then Su Yue'er was seized power, he has been secretly taking care of Su Yue'er on the surface, and he can always get some slightly better meals from the kitchen to send to Su Yue'er, and he is also the one who delivers Su Yue'er's food.

Because he sent delicious food to Lingxi Pavilion privately, the people in Lingxi Pavilion had a good impression of him.

After determining the target, the palace guards quickly attacked and blocked the person directly in the kitchen.

Seeing that he was exposed, this man no longer hid his clumsiness, and injured several secret guards in a row and tried to escape, but in the end he was captured and sent to the dungeon.

Inside the dungeon, the man was tied to a cross-shaped wooden shelf, and Qin Boyong walked in from outside the dungeon and looked the man up and down a few times.

If Gu Muzhi was here, she would definitely be surprised.

Because not long ago, this man had seen her and asked her if she needed the help of her master. After Gu Muzhi refused, he thought that this person had already left the palace, but he never expected that this person not only did not leave, but also mixed into the palace.

"Tell me, who sent you, and what is the purpose of infiltrating the palace?" Qin Boyong sat on a chair with a calm face.

The guard quickly removed the cloth from his mouth, but the man did not speak, but moved his mouth, and at the moment he moved, the guard suddenly moved, and his hand twisted his chin suddenly, and only a click was heard, and his jaw bone was removed.

Generally, there will be poison in the teeth of this kind of spy, and the palace guards have already taken precautions, and their movements are faster than the action of him biting the poison.

The man's jaw dropped instantly, an extremely painful expression appeared on his face, and saliva flowed uncontrollably from his mouth.

Ouyang Qian's cell was not far from the interrogation room, she heard the movement and looked out, just in time to see the scene of the dungeon guards who had always been calm in the past removing the man's chin, and immediately stared at him in fright, and her heart was a little worried.

Qin Boyong shouldn't do the same to himself in the future!
