"Ting Zhu, all of the recent royal grandson's medicine was brewed by you, right?" Originally, this was something that she was very sure of, but Shen Kouqing felt that it was still necessary to confirm once again, whether it was so or not.

"That's not it Esteemed Empress, for the past half a month, Ting Zhu saw that you were not in the mood to eat or drink, and looked extremely worried. Ting Zhu was very worried, and worked hard on your diet, and last time there was a servant girl, Qing Yan, who said that she was an expert in brewing medicine, so I gave her the task of brewing medicine." As Ting Zhu spoke, she felt that something was amiss. She became quieter as she spoke, and did not dare to continue speaking.

"Your Highness, please forgive me!" It was all because of this servant's negligence that he handed over such an important matter over to someone else. If it wasn't for Ting Zhu's momentary negligence, this emperor elder Sun wouldn't have ended up like this! " Ting Zhu knelt down with a thump, feeling exceptionally anxious. She knew that she had been negligent this time, and that's why she caused Song Yichen to be poisoned. That's why her own mother had been slapped by the crown prince's wife.

For a dignified Royal granddaughter consort to be slapped and humiliated in front of so many people, it was simply a great humiliation! And the reason why Shen Kouqing was humiliated today was entirely because of Ting Zhu herself!

"Get up! This matter is not something that you can anticipate. After all, you are still young and do not know that the people of this world are sinister. " Shen Kouqing sighed helplessly. Facing Ting Zhu who was kneeling in front of her, she was really unable to get angry.

She firmly remembered the kindness Ting Zhu had shown her in her past life. In this life, she had been heartless to her all along, and had even punished her? Shen Kouqing questioned herself; she simply could not do it.

"According to what Miss Ting Zhu said, the person who poisoned the poison was most likely that servant named Qing Yan?" The butler asked with a slow but calm voice.

"Yes, very likely." Shen Kouqing nodded and replied.

"However, our current thoughts are only our own guesses. If we want to prove it or not, we still need to conduct a further investigation." Shen Kouqing's eyes seemed to be staring at something, but her thoughts were moving, as she spoke to the butler and Ting Zhu.

"Investigation?" How should he investigate? Empress, Qing Yan's methods are really too high, even you are unable to find out what kind of poison it is. " At this time, Ting Zhu was actually a little worried. After all, investigating a matter was not an easy task.

If there was any particularly obvious poisonous substance, they could still be searched. But now, there was not a single clue.

"You can investigate, Ting Zhu. Today, I will let you concoct the medicine for His Highness, so we can wait and see." Shen Kouqing was scheming in her heart, and told Ting Zhu, who was at her side, to do it.

If it was really Qing Yan's doing, she would definitely increase the dosage when Song Yichen activated the poison, to have the effect of causing Song Yichen's sudden death. But Shen Kouqing had Ting Zhu to be responsible for brewing the medicine, and if Qing Yan wanted to make a move, she would have to do something to push Ting Zhu away, and that would be the best evidence!

was extremely serious during these four hours, and he did not dare to relax even for a moment, as he waited for the murderer to come and throw himself into his trap.

"What's the situation?" Shen Kouqing walked in front of Ting Zhu and asked seriously.

Ting Zhu's expression was very serious, as she shook her head.

"Qing Yan did not make her move?" Shen Kouqing continued to ask.

"Reporting to the Empress, this servant, Qing Yan, has never touched a medicine jar during this period of time. Therefore, this servant feels that this matter, might not have been done by her …." In her heart, Ting Zhu had already thought that perhaps the poison wasn't administered by Qing Yan at all.

Shen Kouqing frowned slightly, as if there was something wrong with this matter.

No! This matter was definitely not as simple as it looked on the surface. Song Yichen being poisoned was definitely not because there was something wrong with his medicine. From the looks of it, there could only be one possibility, and that was that someone else had tried to poison him.

However, she had made this plan today. The most suspicious person didn't have any way to suspect her. The whole matter had indeed become more troublesome to deal with.

"Ting Zhu, bring the medicine over." Shen Kouqing was still unwilling to give up, and said to Ting Zhu.

Ting Zhu obediently carried the medicine that was placed at the side over and placed in front of Shen Kouqing.

Shen Kouqing took the soup, placed it under her nose and took a whiff, as expected!

"There's still something wrong with this medicine!" Shen Kouqing said with certainty.

"Empress!" "Not a servant, definitely not a servant!" Hearing Shen Kouqing's words, Ting Zhu was immediately dumbfounded, she was worried that Shen Kouqing might think that she was the one who did it, hence she quickly kneeled down and said anxiously.

"Alright Ting Zhu, get up. I know that you definitely did not do this." Shen Kouqing faintly smiled at Ting Zhu.

In her heart, she was very clear that Ting Zhu would definitely not do such a thing.

"Thank you for your trust in Ting Zhu, that... Next, I... What should we do? That assassin's methods are so subtle, and this servant has been keeping an eye on him the entire time. He was even able to poison me. This … "" What? "" " Ting Zhu was a little flustered, she had a kind of unexplainable fear towards the "killer", and asked Shen Kouqing in a somewhat flustered tone.

"She is indeed very skilled. However … It was impossible to do it without anyone knowing. There must be something fishy going on, but... What is it? " Shen Kouqing was also a little confused. Her mind was spinning as she muttered to herself, and also seemed to be talking to Ting Zhu.

He had never approached the medicine pot, but he was able to poison it, unless … The poison itself was in the medicine, but his own medicine wasn't a problem at all. Could it be …

Thinking about that, Shen Kouqing's eyes turned towards the medicine pot, and suddenly, as if she remembered something, she walked towards it.

"Empress, did you discover something?" Ting Zhu followed Shen Kouqing and asked curiously.

But Shen Kouqing did not answer, she was only doing her own thing, after all her guess had not been confirmed, it would be better to not say it out loud first.

Shen Kouqing picked up the medicine jar, observing it carefully, both inside and outside, and suddenly realized that the color inside the jar didn't seem to be right.

She stretched out her hand and dug around. As expected!

She dug out some black dregs.

"This is?" Ting Zhu looked at the black dregs, her eyes were wide open as she asked in shock.

"This should be the problem, right?" Shen Kouqing said.
