Qi Lin had only told her yesterday when he found out Gu Dingyan's identity, and he had even told her many secrets that had been passed down in the palace. For example, the Emperor had once decreed that Duan Chengxuan should succeed the throne.

Hearing these words, Duan Cheng Xuan and Su Yu Wan recalled that time.

If Duan Chengxuan hadn't arrived in time, Su Yuwan would have perished a long time ago. After bringing Su Yuwan to the newly built Wang Mansion, she wouldn't have been able to recover from her illness until now.

Then he quarrelled with the Emperor, who said it was all for his own good.

Within a few days, the Emperor had established the Empress as the eldest son of the Xu Family as Crown Prince. Su Yu Wan was still worried when Duan Cheng Xuan and the Emperor broke off their relationship, and at that time, he was only angry for a moment.

If he could drag the Emperor down from the sky, then he, Duan Chengxuan, would personally be able to enjoy the world. He would not hide like this.

"Crack ~ ~" The cup in his hand shattered and tea spilled onto the table.

Gu Danyan quickly covered the tea on the table with the handkerchief. Su Yuwan held his hand with a worried look and observed with her red eyes: "Brother Xuan, what happened that year is over …"

"This King is excited." Duan Cheng Xuan closed her eyes, filtering out all the hostility and anger within them.

Su Yu Wan wiped his fingertips clean, while the maidservant at the side quickly went to tidy up the table. Only Gu Liu Yan saw everything, and only knew that Duan Cheng Xuan was blind and liked this swindler, so she stuffed a piece of pastry into her mouth and continued: "Royal Highness, don't worry, I know what to do, I just want a guarantee from you."

"You know your limits?" Duan Cheng Xuan obviously didn't believe that she was the one who caused such a huge ruckus in the restaurant.

"Of course. I've found Lady Wan'er's antidote for you, and I've even become your scapegoat. Now, I even have to help you deal with the empress. Don't you think you should promise me that?" Seeing him pick up the cup of tea, she then continued, "I don't need much, as long as you don't hurt me in the future, you can leave me some face so that I don't have to go out and embarrass myself. If you don't even agree to this, I'm willing to leave with you, and we'll be strangers in the future."

"Wan-Er also wants your secret recipe and two herbs." Duan Cheng Xuan smashed the cup onto the table with a bang.

"Then promise me." Gu Danyan's gaze instantly sharpened. With her identity, she should not have cowered. She could only blame the original owner for being too cowardly when facing Duan Chengxuan.

Their gazes met, and the two parties stared at each other.

The first one to look was Su Yuwan.

She quickly pulled Duan Chengxuan's arm and pulled him over. In her heart, she thought that it would be best if she left, but on the surface, she still said in a considerate manner, "Big Brother Xuan, we're still hunting. It wouldn't be good if anyone heard."

"Wan'er is right." When faced with Su Yu Wan, Duan Cheng Xuan became as gentle as water.

Gu Danyan, who hadn't received any guarantees, wasn't in a hurry. He only disliked Su Yu Wan more and more. Since Duan Cheng Xuan had already brought her treasure to this extent, why did she still want to court death?

Jade Dragon Snow and the phoenix gall had yet to peruse the ancient book. After all, she had always firmly believed that one's basics were the most important, so she had been studying the medical books here every day. There were still many types of herbs that had miraculous effects, but the variety was many times more than what she knew.

As soon as she thought of medicine, she took out her medical book. Qing Dai also came back and gave a wooden box to Xiao Hai. She didn't know what was in the wooden box, so she went over to ask Gu ZIyan.

Gu Daiyan only smiled at him: "Some of the soul calming items and some nourishment, some of it can be put into the pillow, and then you can sleep peacefully. If there's no fragrance, you can take it to boil the soup and put it in the tea."

"It's actually this magical?" Xiao Hai opened the wooden box and took a light sniff. It was quite sweet, just a little bit bitter.

"Commander Xiao is too kind. Moreover, I still need to flip through the ancient books left behind by your ancestors. I really don't know how to thank you. Just call me whenever you need any small stuff in the future." Gu Danyan bent over towards him seriously, sitting on the chair and bowing to show his respect.

For a medical family like hers, if they took a fancy to the secret methods of other families, they would even need to purify their bodies and burn incense to show their respect. Although their etiquette was old-fashioned, she and her father and grandfather both believed that this was respect for medical knowledge.

Xiao Hai quickly waved his hand, "Royal Consort, I can't accept this."

"Respecting the ancients is what a generational doctor should do." Gu Liuyan just smiled and waved his hand. He then ordered Qing Dai to prepare some things to deliver to Commander Xiao's residence when she got back.

Duan Chengxuan saw everything and sneered, as he thought that Gu Mingyan would rope him in.

"Sister Gu's popularity is really good. Even 12% are full of praise for her." Su Yuwan said softly at the side.

"It's just toying with the minds of others." He personally picked out the pastries for Su Yu Wan and personally fed them to her. It was really sweet.

Gu Danyan naturally heard what Duan Chengxuan said and continued to take the medical book lightly.

It could be said that he was looking down on others with his dog eyes, and his mind was dirty. Everything he looked at was dirty.

The two of them did not get along well, but a scream came from within the forest. A coachman hurriedly ran out from the forest and knelt on the ground while shouting, "Fourth Prince has fallen off his horse! The wild boar in the enclosure injured the Fourth Prince! "

"What!?" Bring out the fourth prince now! " Even Duan Chengxuan abruptly stood up. The Fourth Prince was the closest of the princes to him, and was good at martial arts. Having grown up with him in the army camp, how could he possibly fall off his horse?!

"Prepare the horses." The Emperor's face was ashen, and the Fourth Prince was the flesh and blood in his heart.

"I'll go with you." Gu Daiyan pushed the medical manual into the arms of Qing Dai and followed closely behind Duan Chengxuan.

"What are you doing!?" "Don't mess around!" Duan Chengxuan swung her away.

However, she continued to chase after him. After Duan Chengxuan mounted the horse, she grabbed onto him without a care in the world, "If he falls down and breaks his bones, you guys can touch him at will. Aren't you afraid that he'll die or lose an arm or a leg in the future!?"

Fortunately, she had a medicine kit on her waist.

Seeing her so persistent, Duan Chengxuan thought of her completely disregarding the injured person. After hesitating for a long time, he still immediately brought her up to the room and said, "If I let Yu'er get away with anything, I won't forgive you!"

"Rather than threatening me, why don't you hurry over!" Gu Danyan stared at him.

"Giddy up!" Duan Cheng Xuan glanced at her in a threatening manner as well.
