"Your Highness, this herb is poisonous. If you take too much, it will affect your body in the future." The voice of an imperial physician called back Gu Danyan.

Gu Liuyan leaned over to take a look, then thought for a moment: "It is indeed not good for the body, but there is a conflict between the Bu Zheng Grass and these two herbs. Gu Liuyan leaned over and looked, then thought for a moment:" It is not good for the body, but there is a conflict between the Bu Zheng Grass and these two herbs.

After the two imperial physicians heard this, they gathered together to discuss in detail how this could be done.

Duan Chengxuan and the empress dowager briefly exchanged a few words before arriving at Gu Liuyan's side. He wanted to bring her back to the estate, so she handed over her prescription to the two imperial physicians, then took away a few books from the Imperial Physician Guild along the way, in order to take a good look at them when she returned.

Seated in the carriage, she impatiently opened the medical book, only to hear Duan Chengxuan say, "To you, medical skills and medical knowledge seem to be more important than anything else."

"It's just that my interest is piqued, just like the soldiers who like to fight, and the scholars seem to enjoy the elegance." Gu Ming didn't even raise his cigarette, but started to carefully read the contents of it after a while.

However, he didn't notice that Duan Chengxuan was constantly watching her side profile.

The two of them had once again gotten married yesterday, but Duan Chengxuan felt that the Gu Pingyan in his eyes seemed to have changed a lot, and was becoming more and more gentle and lovable. He only helped her brush the hair by her ear, but he saw Gu Pingyan's spirit shake as he stared at him for a long time.

"What's wrong?" Duan Chengxuan was slightly stunned, but his fingers were still stuck at her temples.

"I suddenly thought of something." Gu Liuyan finally remembered the few letters from before. He still had to ask this question after all. He thought for a moment and then said in a low voice: "Do you think there's any possibility that the Emperor was the one who did the Yun Family's business?"

"What makes you think that?" Duan Cheng Xuan frowned, then why did she mention what happened in the past?

Gu Danyan naturally had the intention to probe him. After pondering for a while, he passed the medical book in his hand to Duan Chengxuan, "I saw that there were many ancient books and prescriptions in this Imperial Hospital, so I wondered, could it be that the Emperor wanted the Yun clan's secret formula, and later on, because he couldn't find it, he took out the punishment for my Yun clan. What he wanted, was the secret formula?"

The medical manual was densely packed, so how could Duan Chengxuan possibly understand it?

Gu Daiyan carefully sized up Duan Chengxuan's expression, and when she noticed that his expression was normal as usual, she didn't know why, but she heaved a sigh of relief in her heart.

"Is the recipe I gave you still there?" Gu Daiyan lightly touched him.

"Yes, what do you want to do?" Duan Cheng Xuan nodded.

"Go and give this recipe to the Emperor. Jade Dragon Snow and Phoenix Bile are two rare medicinal herbs and very difficult to find." Gu Daiyan winked at him playfully.

Duan Chengxuan nodded in agreement, then returned the medical book in his hands to Gu Daiyan. There wasn't a single flaw on his face.

Gu Danyan was also helpless in his heart. After all this time, she had been the one at a loss for a long time before the wedding.

But unfortunately, when she lowered her head to read the book, she didn't notice the worry on Duan Chengxuan's face.

If Gu Daiyan had known about the slandering of the Yun clan back then, perhaps his love for her today would have been as fleeting as the clouds in the sky.

As the carriage slowly headed towards the prince's mansion, the passersby all glanced at it. They all had a lot of ideas and gossip about this princess of the imperial court.

Amongst the crowd, the beige robed Hua Li pulled down her cloak and softly whispered to the people around her, "Father, just who is this Gu Mingyan? She actually doesn't care about your life at all."

"Don't worry about her. You just need to protect your elder brother." The one who spoke was none other than Gu Cheng.

Gu Cheng watched the Wang Mansion's carriage slowly drive away with a cold gaze, but his eyes remained as cold as ice.

Big brother does not need my protection, it's just that Gu Zixian said that the Jing King seems to have the intention of cooperating, but you have betrayed him before, he needs to meet with you, what should I do? Hua Li continued to ask.

"After three days, just find a random restaurant's private room." Gu Cheng raised his hand with a smile on his face, "Since Third Prince isn't willing to cooperate with me any longer, I'll just cling to the Jing King and let this brat, who doesn't know how high the sky is and how deep the earth is, regret it."

"That's right, father and brother are so smart. The third prince doesn't know what's good for him. Why is it that he doesn't want to act against the fourth prince? He can't be soft-hearted enough to do anything." Hua Li also laughed softly, but very soon, she pulled Gu Cheng into the crowd and disappeared.

After the carriage entered the manor, Duan Chengxuan originally wanted to accompany Gu Danyan properly, but he heard the message from Cheng Shan, "Just now, Prime Minister Gu sent a message inviting you to go to the Hundred Scented Tower's private room to discuss business today. Three days later, we'll arrange for Gu Cheng to meet you."

"Go and prepare a set of clothes." Duan Cheng Xuan nodded.

He held the red jujube that Azi had slipped over and said softly: "He must have started to negotiate conditions to meet you today. Tell me, what other things is in his possession that are worth your cooperation with?"

Duan Chengxuan thought for a moment before smiling. "It's probably his mouth."

"It's possible." "Father actually dares to do such an outrageous thing. Perhaps he might have already thought of something else a long time ago, and since he has no choice now, he has no choice but to escape the wrath of the Emperor, if he wants to come out again in the future to stir up trouble, he must change his dynasty."

"Do you think they would instigate me to kill my royal brother?" Duan Chengxuan frowned. Unless he had no other choice, he would absolutely not do this.

Perhaps the two younger brothers had been provoked into discord, but now, the two of them had thoroughly seen through each other.

"It is better to believe than not. He can even subdue his children, so of course he can let you do whatever he wants for the throne. If he doesn't keep his last line, then he will lose everything." Gu Daiyan quickly waved his hand.

"Of course. Royal brother's informants are all over the Sky Flame. If I really want to do this, he can't hide any information no matter what." Duan Cheng Xuan nodded, then lightly patted Gu Qing Yan's shoulder: "Rest well, I'll be back for dinner."

"Right." Gu Danyan nodded as he held the red date in his arms.

The two of them walked in opposite directions, passing each other. However, everything seemed to have changed.

After returning to her room, she took out the three letters and carefully read through them once more. However, she didn't see any flaws on Duan Chengxuan, causing suspicion to arise in her heart.

And when she saw this letter, the first thing that came to her mind was her mother.

Previously, when he had heard about the battle between the Wind Pavilion and Gu Cheng, he had told them a lot of things regarding ghosts and gods.

That was the reason why she had asked the Third Prince to investigate his mother's matters. There were no ghosts or gods in this world, but there were certain things that created ghosts and gods.

But why was the matter regarding the conspiracy of the Yun clan and Jiang Yan also related to the theory of ghosts and gods? Was it to convince the emperor that the Yun clan had a greater motive for doing so?
