"What's the problem?" Ting Zhu did not understand, but she guessed that this black thing should be some kind of poison, but she could not be sure.
"Yes, this is a medicinal ingredient that only contains a very small amount of medicinal ingredients. Qing Yan is very smart, and knows where the problem lies from the first look at the medicinal dregs, so she refined this medicinal ingredient into a large amount of essence and smeared it on the inner wall of the medicine jar. When the medicinal ingredients are fried, the high temperature will melt the medicinal ingredients on the inner wall of the medicine jar and fuse with the original soup. Shen Kouqing revealed the whole thing, while talking, she couldn't help but sigh at Qing Yan's brilliant techniques.
Actually, it was too rare for her to be able to be this flawless without anyone noticing. If she was in the right position, she would definitely be a talent.
"So that's how it is! Esteemed Empress, this servant remembers, the medicine jars in our house were always cleaned by Qing Yan, she was sent by the Crown Princess to do whatever she wanted, we could not say anything, and could only try to kill her. " Ting Zhu seemed to have thought of something as she said this.
"Qing Yan was sent by the princess consort?" Shen Kouqing didn't seem to know the origins of this person and was a little doubtful.
Since it was someone sent by the princess consort, why would they make a move against Song Yichen? Since the tiger poison was poisonous and did not kill him, could the Crown Prince's wife be trying to punish him? Was Song Yichen's life just a joke?
It was impossible that the Crown Princess was so anxious. She wasn't pretending. No matter how she pretended, it was impossible for her to be so real. After all, a mother's care for a son was something normal people couldn't understand.
Therefore, there was only one possibility left, and that was that Qing Yan had already been bribed by someone.
Perhaps he had long since been someone else's chess piece. After sneaking into the Crown Prince's Palace and becoming the Crown Prince's consort, he could come to the Palace of the Great Emperor and hide for a period of time before finally taking action.
Qing Yan could be considered a person who hid her abilities well. In such a long time, Shen Kouqing had not noticed the existence of such a person in her village, and even he did not know her background.
"That's right!" Originally, this servant didn't know that when she said she was responsible for the medicinal herbs, she personally told this servant to take good care of His Highness' safety. When this servant heard this, she didn't stop her. Ting Zhu said, his face still had a look of remorse, as she lowered her head.
So it turned out that Qing Yan had come prepared.
"It's nothing. Today, the Japanese palace is going to drag her out and deliver her to the Crown Princess. The Crown Princess is going to personally take care of the people she sent." Shen Kouqing's eyes became sharp.
Although she still showed some courtesy when facing her elders, she definitely wouldn't be slandered or insulted so casually.
Shen Kouqing was not the Shen Kouqing of his previous life. In this life, she would not compromise, and would take back all the justice for him, step by step, pressing him down. She would disappoint her in his previous life, hurt him, and face off against the people who tried to kill her in this life, cleaning up all of them so that they had no room to regret.
Yes, she was no longer weak. After all, this was a world where the strong preyed on the weak.
Actually, at this moment, in Shen Kouqing's heart, he was extremely disdainful towards his princess consort. She didn't know how she would feel when she found out that the person she had sent over had actually murdered her son.
That would be if Qing Yan was one of the people she sent over. If one thought carefully, one would not know how she would act in the future.
"Butler!" Shen Kouqing called out in a low voice, and the butler immediately came in. Just now, the butler had followed Shen Kouqing here.
"What orders does the Empress have?" Hearing Shen Kouqing's call, the butler immediately walked in.
"Go and call Qing Yan to the great hall. I want to interrogate him myself! What exactly is the reason for the murder of the emperor's eldest grandson?! " Shen Kouqing's words were very sharp and her tone was filled with power. As she spoke, she flung her sleeves and walked towards the direction of the great hall.
The butler hurried to Qing Yan's room and stood at the door, watching as it closed.
Although Qing Yan was only a slave, she had still been sent by the Crown Prince Concubine. Naturally, her position was relatively high, so she lived alone, perhaps because of this, no one would be able to see what she had done, and no one would have evidence to prove that she was the one who had done it.
"Miss Qing Yan, Miss Qing Yan? Royal granddaughter consort will pass on this message to you. " The butler was very polite and called Qing Yan "Miss".
Due to her status, everyone in the mansion respected her.
Just like how they called Ting Zhu "Miss Ting Zhu", it was a principle. After all, they were the subordinates of powerful people, they could not afford to neglect them.
After calling out to him for a while, Qing Yan still did not have any reaction. This made the butler feel unhappy, but he was still suspicious.
From the moment Shen Kouqing told Ting Zhu to boil the medicine, she had sent people to keep an eye on him and did not do anything abnormal. She should not have left the house by now, but, if she was in the room and did not answer, was that not a little too polite, or perhaps it was a little too excessive?
The butler thought about it and steeled his heart. He reached for the door and pushed it open.
Originally, he still had a little bit of resentment, but when he pushed open the door and saw the scene inside the room, he was shocked and forgot what he was thinking about.
"Someone, come!" The butler shouted and the mansion's hidden guards came out, seeing Qing Yan lying in a pool of blood.
In the lobby, Shen Kouqing was drinking tea. On the surface, she looked very calm, but in reality, her heart was thumping. When Qing Yan came, how would she ask?
Normally, those who carried out missions would clench their teeth tightly, they would not be able to pry anything out. Shen Kouqing did not have any confidence in her ability to interrogate any criminals.
"Empress, you don't have to worry. As long as Qing Yan comes over, there will definitely be a way to find out who the mastermind is. This matter can be easily resolved!" Ting Zhu seemed to have noticed the worry in Shen Kouqing's heart, and she opened her mouth to console her.
Ting Zhu nodded, she did not know what to say, after all, she was just a small servant and could not help, she could only be a spectator.
