Your Highness, please stop chasing me.

Upon hearing this, Mu Xue finally remembered who this Prince Jing'an was.

She remembered that at the time, Granny Kang had proudly mentioned this person: Su Jianan, the Prince of Jing'an of Dongli Kingdom, was the most capable person to inherit the throne of Dongli Kingdom back then.

This person was also the fiancé of his mother, Princess Shen Wan.

If he hadn't died suddenly, Shen Wan would have already married into the Dongli Kingdom.

It was also because of him that Shen Wan was past the age of marriage and no young master from any prominent family dared to propose to her.

After listening to Ye Yi and Mu Qinghe's words, something suddenly flashed through Mu Xue's mind. She asked thoughtfully, "How were you able to determine back then that the corpse belonged to this Prince Jing'an?"

"This," Mu Qinghe and Ye Yi exchanged a glance, and Ye Yi shook her head to indicate that she did not know.

Mu Qinghe recalled carefully before speaking: "I remember that at that time I had already escorted Wanwan to the capital of Dongli Kingdom, but when we were almost at the border, I suddenly received news that Prince Jing'an had been assassinated. I was not sure if the news was true or false, so I stayed put and sent people to Dongli Kingdom to investigate."

Then he called out to the door, "Mu An, come in."

Mu An strode in, looking at the people present with a puzzled expression. "Master?" he asked, confused.

Mu Xue and Ye Yi also looked at Mu An who had just walked in.

“I remember, the person I sent out to gather information back then was Mu An,” Mu Qinghe explained.

He then said to Mu An, "When the news of Prince Jing'an's death came out, tell Doctor Gu and Lord Ye what you found out."

"Oh, okay." Mu An thought for a moment before beginning to speak: "I remember, when Master was escorting Madam to Dongli Kingdom for a marriage alliance, news of Prince Jing'an's assassination arrived before they even reached the border. Master sent me to Dongli Kingdom to gather information. I remember that the border guards of Dongli Kingdom were extremely tight at the time, and I could only travel through several small villages and finally bypass the Eastern Ridge to reach the border city of Dongli Kingdom..."

He paused here, and Mu Xue and the other two were not in a hurry. This matter had happened a long time ago and needed to be recalled slowly.

Soon, Mu An continued, "When I entered the city, I heard everyone on the streets, young and old, discussing the assassination of Prince Jing'an. I wandered the streets and alleys of the city, lying in wait for a day and a night, before I could find out the truth. It was Consort Yun herself who identified Prince Jing'an's body."

Mu Xue asked, "Who is Consort Yun?"

Mu Qinghe replied, "Consort Yun was the favorite concubine of the King of Dongli at the time, and the birth mother of Prince Jing'an."

Yoruichi continued, "After the Prince of Jing'an was buried, Consort Yun was so heartbroken that she also passed away."

Upon hearing Ye Yi's words, Mu Xue raised an eyebrow and said, "The death of Consort Yun is very suspicious!"

"Yes, when the Prince found out about this, he also felt that Consort Yun's death was very suspicious, but when we tried to investigate Consort Yun's background, we found nothing," Ye Yi continued.

He thought for a moment about how to describe it, and Mu Xue said it for him: "It's as if this Consort Yun appeared out of thin air. Isn't that right?"

“Yes, the Ancient Physician is right. We can’t find out when this person appeared in Dongli Kingdom at all,” Ye Yi nodded hurriedly.

"So you didn't infiltrate the Dongli Imperial Palace to investigate?" Mu Xue asked.

At this moment, Mu Qinghe said, "Master Gu, you may not know this, but the Dongli Imperial Palace was built according to the Five Elements and Eight Trigrams, and all the people inside are assassins of the Dongli Kingdom."

Mu Xue asked in surprise, "So ruthless??"

The palace was filled with assassins; they were practically invincible.

Mu An then said, "When I was in the border town, I heard a rumor."

Mu Xue asked curiously, "What rumor?"

"Back then, in order to find out about Prince Jing'an, I listened to everything that was said about him. I remember that many people were saying that Consort Yun was someone the old Emperor Dongli met when he was in Nan Yue Kingdom. It is said that Consort Yun has not changed her appearance for more than ten years, which is why she has always been deeply favored by the old emperor." Mu An told Mu Xue and the others the rumors she had heard back then.

Mu Xue suddenly asked Mu Qinghe curiously, "Did General Mu ever see Consort Yun back then?"

Mu Qinghe pondered for a long time, then shook his head hesitantly and said, "I was fortunate enough to attend a four-nation conference. I was standing behind the late emperor at the time, but it was really strange who came. Even the unfavored concubines attended the banquet, but the favored Consort Yun never showed up."

Mu Xue glanced at Ye Yi, who understood and made a note of it. She planned to send a message to Ye San when she got back so that he could investigate. After all, there were many people and things going on at the Four Nations Conference, and there were bound to be some oversights.

Mu Xue asked, "General Mu, of these people we've been talking about, who do you think is the most suspicious?"

Very well, the issue of offending people has been relayed back to Mu Qinghe.

"This, Doctor Gu, it's definitely impossible for the Prince. The Prince of Jing'an of Dongli Kingdom has been dead for over twenty years. Isn't that also unlikely? As for the Prince of Lingxi of Nanyue Kingdom, I had a conflict with her a couple of years ago, but I've met her before. Judging from her character, she's straightforward and will settle a score on the spot. I really don't know anything about her!" Mu Qinghe said with difficulty.

Mu Xue found it amusing to see Mu Qinghe scratching his head and racking his brains.

She sat up straight, interrupting Mu Qinghe's thoughts, and said, "Since we can't be sure who is behind this poison, I think it's best not to remove the poison from Young Master Mu's body for now."

"Won't this cause any harm to Feng'er's body?" Mu Qinghe asked.

“Of course not, but if we remove the Gu worms now, it will cause great harm to the young master’s body. The other party will notice immediately, and then they will have a backup plan that we won’t be able to detect easily,” Mu Xue said.

Yoruichi agreed with Muyuki's statement, and Ye Shangyuan had also analyzed the same point with him.

Ye Yi spoke up, "The old physician is right, and the prince thinks so too. The prince said that the person who used the Gu poison must have spies planted around the general, and not just the eldest son."

Remembering what Ye Yi had said earlier, Mu Qinghe asked, "Your Highness said you found out who used the Gu poison. Who is it?"

He clenched his fists as he said this, his heart filled with anger.

Mu Xue poured a bucket of cold water on him: "General, even if you really know who it is, you can't take action. Why add to your troubles?"

Mu Qinghe slumped into a chair, covering her face with her hands.

At this moment, Mu An asked, "Master Doctor Gu, since the person who cast the Gu poison is right next to our young master, can't we control him and find out who's behind it?"

“They’ve all been cursed, so we can’t get anything out of them,” Yoruichi replied.

The assassin he captured earlier was in the same situation.

This is also a method to prevent leaks.
