She remembered clearly where every medicinal herb in the house was placed, because Shen Hezhi needed her to detoxify, so no one else could come in this room where the medicinal herbs were placed except her.

But at this moment, the nearest medicinal herb in front of Yan Hecheng was placed in the wrong position, and it was reversed from the medicinal herb next to it.

This phenomenon made Yan Heru think about it, she took out a special silver needle, most of the silver needles are not able to test the poison, but she is different, her silver needle is also made according to the method recorded in the "medical book".

Thinking of that "medical book", Yan Heru recalled it vigorously, and she vaguely remembered that the name of the book was "Poison Doctor".

Putting aside the messy thoughts in his mind, Yan Heru picked up this special silver needle and put it on the medicinal herb to try it, and found that this medicinal herb was actually tampered with.

Yan Heru rolled her eyes, put away the silver needle, she walked to the other table and picked up a medicinal herb.

There were many tables in the whole room, and on each table, different medicinal herbs were placed.

After she picked up the herb, she went to another table, looked for it, and picked up another herb.

Eventually, she returned to the doorway and picked up the herb that had been tested to be poisonous.

This medicinal material is a necessary medicinal material for the treatment of cold poison, and the number is extremely rare, and there is only such a medicinal material at present.

Therefore, the person who poisoned this medicinal herb must not want the Nine Princes to recover, and must be extremely familiar with the structure inside the Nine Princes' Mansion.

Because it was only a matter of one night and one morning from Yan Heru leaving the palace to coming back now, this time is not long, but if it is not clear, it is absolutely impossible for the people of the palace to find this medicinal material accurately.

But it doesn't matter if she is poisoned, Yan Heru can be called the "Holy Hand Poison Doctor" in modern times because she knows more about poison.

I just found a few other medicinal herbs, just to alleviate the poison in this bead of medicinal herbs.

Yan Heru took these medicinal herbs to the center of the room, and there was a small stove in the center of the room that specialized in boiling medicine.

During this time, she did not leave the stove for a single step, but she clearly felt that someone was watching her outside the door, which made the corners of her mouth smile.

Do you want to see if I haven't used this poisoned herb, heh, as you wish.

Yan Heru decocted the medicine, cleaned up the house, and went to Shen Hezhi with the medicine she had decocted, before she left, she found that someone had poked a hole in the door, thinking that this should be the person who had been observing her just now.

Yan Heru smiled, pretended to be as usual, and walked to Shen Hezhi's room.

"Lord Wang." Yan Heru called softly.

"Come in."

Yan He pushed the door in, she felt that the sight behind her had been watching her enter the house before leaving, presumably to go to the room where the medicinal herbs were placed, to check whether the medicinal herbs had been used.

Yan Heru closed the door, put the medicine on the table, hid behind the door and looked, and sure enough, he saw a figure flashing not far away.

Shen Hezhi saw Yan Heru's strange behavior, put down the pen in his hand, and asked, "What's wrong?" ”

"There must be a lot of people in your palace who have bad intentions for you." Yan Heru replied.

Shen Hezhi frowned and said, "Why do you think so?" ”

"This essential medicinal herb of yours, but someone has tampered with it, the room where I put the medicinal herbs, but no one can enter it except me, do you think it was someone who accidentally broke in?" Yan Heru replied lightly.

While answering, he put the medicine he brought into a bowl, and then brought it to Shen Hezhi, Shen Hezhi didn't ask much, took it directly, and drank it.

His actions made Yan Heru frown, and asked, "I just said that your essential medicinal herbs have been tampered with, don't you just ask if there is a problem in this bowl of medicine?" ”

"This bowl of medicine was made by you yourself, so I believe in you." Shen Hezhi smiled softly.

His smile made Yan He lose his mind for a moment, there was once such a gentle man who believed in her so much.

Yan Heru felt a pain in his heart.

Shen Hezhi found that Yan Heru's expression was a little strange, put down the medicine bowl in his hand, and looked at her worriedly, "Are you okay?" Not feeling well? ”

"I'm fine..."Yan Heru was pulled back to his thoughts by Shen Hezhi's words, "Lord Wang, let's take a good look at the people in your palace, this time I have a way to solve it, but it doesn't mean that every time I am passive, I can find the medicinal materials in my hands and feet, and I can solve it." ”

Yan Heru's words are not false, although she can solve a lot of poisons, but the world is so big that there are no surprises, she doesn't think she can understand all the poisons in this world.

"Okay, I will."

"The person who did it this time should be extremely familiar with the structure in the palace, and it may be the closest person around the prince, or the closest person, who accidentally revealed some news." Yan Heru continued to analyze.

She was very attentive when she analyzed, so she didn't notice the appreciation in Shen Hezhi's eyes.

"And there's more." Shen Hezhi echoed.

"First of all, not many people know about the cold poison of the prince, so since this person destroys the medicinal materials, he doesn't want the cold poison of the prince to be cured, which means that this person knows very clearly that the prince has cold poison on his body."

"Maybe this person has something to do with the cold poison in the prince's body at that time, um..." Speaking of this, Yan Heru suddenly raised his head and looked at Shen Hezhi, "I don't know, Lord Wang, do you know who gave the cold poison... If the prince already knew about this matter, then there was no need to listen to my random analysis here. ”

"I don't know who ordered it, but your analysis is very reasonable, I thought that this palace had been cleaned up by me enough, but I didn't expect that there were still fish that slipped through the net, thank you madam." Shen Hezhi smiled softly again.

Although Shen Hezhi often shows this kind of charming smile, Yan Heru still feels moved when he sees it, not because of any feelings, but simply because of Shen Hezhi's "beauty".

Thinking of Shen Hezhi's "beauty", Yan Heru suddenly remembered that there was a historical figure in his world, and because he was so beautiful, he had to wear a mask when fighting.

If Shen He is on the battlefield, I'm afraid it will be like this...

"Ma'am? Are you deceived by your husband's beauty? Shen Hezhi said with a smile.

Yan Heru swallowed his saliva in embarrassment, and was about to pack up his things and leave, but at this moment, someone suddenly knocked on the door.
