After Ye Zichen cleaned his hands, Gu Danyan also calmed down a bit.

Yun Qingyang brought her back to the inner room and found out that there were tens of thousands of books on the second floor as well. Although they were not expensive, they could be found in a variety of books and all kinds of illnesses were recorded in them.

Yun Qingyang told all of this to Gu Danyan, asking her to study this ancient scroll. She also gave her the Yun Family's identity token, and sent her away in a hurry.

The courtyard quieted down as Yun Qingyang suddenly opened her eyes. Yun Fu, who always had a smile on his face, walked in and said softly, "The young miss has already left. Duke Jing did not hear anything at all."

"That's good." Yun Qingyang let out a few soft laughs before closing her eyes again, ready to take a nap.

At the same time, a black figure silently snuck into the room Duan Cheng Xuan was in.

Even under the clear sky, he was dressed up as he knelt on one knee. "Reporting to Your Highness, there is an expert guarding Yun Qingyang's compound. Your subordinate does not dare to go over."

"This Yun clan …" Duan Cheng Xuan shattered the goblet in her hand with a cold gaze.

In the eyes of the royal family or the officials who climbed up, the Ling Nan Yun family was famous for its mysteriousness. Although they lived in Ling Nan, no one knew where their family was, but for hundreds of years, the descendants of the Ling Nan Yun family had been in contact with the current emperor. Other than the emperor, no one knew whether they were real or fake.

Who would have thought that Yun Qingyang would be able to have experts stand guard in this small Prime Minister's Estate?

Gu Danyan put the Jade Dragon Snow and Phoenix Bile into the pile of herbs and let Yun Fu take care of them. Along the way, he just frowned as he looked at his hands. As soon as he used a bit of strength, his hands would start shaking.

He definitely couldn't use this needle anymore.

The poison did not seem to be in a hurry, as it would take more than ten years to spread throughout her body. She was confident that she could temporarily suppress the poison, so long as she took the medicine before acupuncture, her hands would not tremble.

She lowered her head to look at her hand, but who would have thought that she would run into a wall of flesh.

"Ah!" With a low cry, she staggered a few steps back and covered her head with her hands. When she lifted her head and saw Duan Chengxuan's ice-cold face, she immediately steadied her footing. Rubbing her aching chest, she said in a deep voice, "Prince, it's fine if you just stand here and wait for me. There's no need to be silent, right?"

"Hand over the phoenix gall and Jade Dragon Snow." Duan Cheng Xuan grabbed her wrist.

It would be a waste if she gave them away, so she steeled her heart: "Phoenix gall and Jade Dragon Snow are not weeds on the ground, and these two herbs are still in the Ling Nan Yun Family. If I want to get them, I have to remove the poison from my body and go there myself."

"I think you just don't want to hand it over!" Duan Cheng Xuan raised his hand and strangled her.

Gu Liuyan's breath tightened and her face turned red. She looked at him with her burning eyes: "If you don't believe me! Get Mu Qing to check his pulse for me! "

Duan Chengxuan shook her off. Gu Liuyan fiercely coughed as he held onto the pain on her neck, then he propped himself up using the tree trunk as he climbed. His chest seemed to be hurting even more.

Mu Qing hurriedly rushed over, and under Duan Chengxuan's dangerous gaze, he checked Gu Daiyan's pulse. His brows knitted, and he once again checked his pulse in disbelief. "What kind of poison is this? I've never seen it before."

Duan Chengxuan frowned. Only after seeing Mu Qing seriously checking his pulse a few times did he manage to believe it.

"Now, you should believe it, right?" Gu Danyan's face was pale. He sat on a stool and continued, "Grandfather said that I am a foreigner after all. I will not get the secret recipe until the day I inherit the Yun Family's legacy."

"If that's the case, does that mean I have to help you inherit the Yun Family's legacy!?" Duan Chengxuan's gaze was as terrifying as a vulture's. Mu Qing only lowered his head as he retreated a few steps, his brows tightly knitted together.

"I don't need your help, but you only need to know one thing. The only one who can save your beloved Wan'er right now is this descendant of the Yun Family in front of you. Since I've promised you, I will fulfill my promise. Gu Liuyan held onto her chest, and Mu Qing walked over as if he still wanted to take her pulse, but she swung him away with a light smile. She only looked at Duan Chengxuan with determination for the sake of a guarantee.

After all, he couldn't let this prince bully her every day, right?

The Yun clan was mysterious, and the ones that had appeared in front of him were only Yun Qingyang and Gu Daiyan. If he really lost this recipe that allowed Wan'er to recover completely, then there would be something wrong, not to mention that Wan'er had been sick for a long time, and would have to wait another year to recover.

It was a pity that he couldn't give Wan-Er a name …

"Alright, This King agrees." Duan Cheng Xuan nodded.

I still need to study all kinds of herbs. Although the recipe is not in my hands, Doctor Mu Qing knows about it, so I can try out the effects of the other herbs. I hope that the Prince and Lady Wan-Er will show mercy. She smiled, and her face turned even paler.

Grandfather didn't know that she had been injured in the chest. Now that she had received the poison, the wound in her chest was as painful as if it was on fire.

Seeing her slowly stand up, Duan Cheng Xuan's face was filled with pain. He subconsciously stepped forward to support her. "This poison …"

"I will definitely cure this poison quickly, so as to inherit the Yun clan's legacy. Prince, please don't rush me." Gu Liuyan only thought that it was because he was in a hurry to get rid of the poison and wanted her to go back to inherit his skills, so he grabbed his arm and straightened himself. He felt a little better, and then he gently let go and smiled: "It's about time, Your Highness should take me to say goodbye to Father and Aunt."

Duan Chengxuan felt that his hand still held the warmth of Gu Daiyan's wrist, but he actually didn't want to hurry her up.

"Big Brother Xuan …" A soft voice came from behind.

He only turned his head around to support Su Yu Wan, who was holding onto the weak willow tree, and Su Yu Wan had a smile on her face. However, he clearly saw the actions of Duan Cheng Xuan and Gu Ni Yan, and a trace of gloominess flashed in his eyes as he lightly coughed a few times.

"I'll be right back." Duan Chengxuan's heart ached as he patted her back. He didn't expect that she would become so weak after just one trip out. He ordered, "Mu Qing, take good care of Wan'er."

After handing Su Yuwan over to Mu Qing, he went to the front hall and bid farewell to Gu Daiyan.

Gu Zixian, who was at the side, saw that the two of them had a good relationship, and felt dissatisfied. Taking advantage of the crowded situation, he walked forward, pretended to stagger a few steps, and fiercely crashed into her back.

Gu Ming Yan was already in excruciating pain. When Gu Zixian bumped into her back, he really wanted to knock out her bile. His vision turned black and he fell forward uncontrollably.

A hand caught her steadily.
