Even if she died, she didn't want anyone to know.

Gu Danyan carried the book and walked out, while Duan Chengxuan stopped her before she boarded the carriage.

"What's the matter, King Jing?" Gu Daiyan tidied up the veil covering his face, his expression calm.

"Let's talk." Duan Chengxuan's tone carried a sense of coercion that couldn't be refused, and he even raised his hand in an attempt to grab her wrist.

"There's nothing more to talk about between us." She leaned into his embrace and whispered into his ear: "The friendship between you and Su Yu Wan for more than ten years is something I can't compare with. You can kill me for her, but you can't kill her for me in the end."

"You may have suggested this. You should know that I also want a truth." Duan Chengxuan could vaguely smell the scent of the medicinal plants on her body. Before she left, a hand lightly pressed onto the back of her neck as he continued, "I only need you to give me some time."

Gu Danyan had always understood the general situation and knew when to advance and when to retreat.

He thought that Gu Mingyan would give him time to continue investigating. When the war ended and Jiang Yan calmed down and things went back on track, he would personally bring Su Yuwan to give her an explanation.

"You think I'm going to give you time to sympathize?" Gu Liuyan couldn't help but sneer. She leaned into his arms and laughed: "Back in the King's Manor, did you ever give me a chance to breathe?"

Duan Cheng Xuan vaguely felt that Gu Xuan had changed.

This kind of feeling made him extremely impatient. He could only pull her into his embrace. "In the end, she is still my junior sister …"

Gu Danyan's eyes flashed with a trace of disappointment, before it was immediately replaced by a brimming smile.

After struggling free from Duan Chengxuan's embrace, she took a few steps back with a chuckle. "I regret reminding you of the truth. I should have followed Su Yu Wan's example and hid it from you."

"You can still take revenge …"

"Is it really different, Duan Chengxuan?" He looked over his shoulder at Su Yu Wan who had just jumped down from the carriage. A faint smile appeared on his face as he said: "She is still Crown Prince Jing, so I can't touch her. But in a few days, I will destroy her."

Even if she only had a few years left in her life, she wouldn't let Su Yu Wan still live in this world.

Duan Chengxuan frowned. However, Gu Daiyan had already walked quickly towards the inn, making the soldiers of Er Dan follow closely behind her, not moving an inch away from her.

As soon as he returned to the inn, Gu Daiyan took the excuse that the boat was too heavy to see anyone.

Only by carefully inspecting the ancient scripture in the room did she realize that the phoenix gall had already been added into the death-like medicine. Although phoenix gall is hard to find, the roots underneath it are not all that difficult to find. After all, not all of them can grow phoenix gall. At most, the phoenix flower would bloom.

However, this medicinal herb was the root that gave birth to the phoenix gallbladder. It was extremely poisonous and colorless when it entered the water, there was no smell to it.

She had never heard of this before, so she naturally did not know anything about it. However, when she thought about it again, even if she had not faked her death to leave that day, Su Yuwan should have brought out this trump card to put her to death.

"There is no solution." Gu Liuyan closed the ancient book with a heavy heart, feeling very upset.

Indeed, phoenix gall is rarely seen, and since the phoenix gall stem is a highly toxic poison, it naturally wouldn't be known by the world. Even if people knew, it would only be used for use, and very few people would be able to find a way to cure this kind of poison.

According to her own calculations, if she could find a way to prolong her life, perhaps the medicinal wine that she had soaked in Jade Dragon Snow could give her a way to extend it. However, without such a method, her heart would not be able to withstand the poison for at least two years.

After some thought, she still wrote down a list and sent someone to buy a large amount of medicinal ingredients.

"I don't want to die." Gu Danyan mumbled to himself.

Rather than sit still and wait for death, she wanted to develop the antidote for herself.

The test subject was only her life.

Duan Chengxuan didn't find it strange when he found out that a large amount of medicinal materials were sent to the inn.

Gu Liuyan always helped He Jin solve some difficult problems. He was already used to hoarding large amounts of medicinal herbs.

"Cheng Shan, send someone to investigate what happened that year and find the Zhu siblings. Perhaps they will know more." As he gave his orders, his ice-cold gaze landed on Su Yu Wan's head. "I hope that what you have said is all true."

"Master and mistress treated me so well, how could Wan'er bear to do it!"

Tears fell down from Su Yuwan's eyes. Her fingertips tangled up with the material on her clothes. "I am willing to apologize for what I did. As long as Big Brother Xuan …"

"If you really want to apologize, you might as well stab yourself in the heart."

Su Yu Wan's body trembled, but she didn't dare reply. She could only curse at Gu Pingyan in her heart before raising her head shakily, "Big Brother Xuan, I was pretending to be sick to protect myself at that time. I only did everything after that because I hoped you could drive her out …"

With this, he hoped that Duan Chengxuan would be more lenient towards her.

"In the future, you will only have the false name of Crown Princess Jing. Don't force me to kill you." Duan Cheng Xuan interrupted her, and her icy cold gaze was already ignited with killing intent. "Do you know how many people were harmed by the things you did in the past?"

Su Yu Wan bit her lower lip and raised her head unwillingly: "Big brother Xuan, aren't we the same?"

"You once said that I would do anything for me, but now, you are only doing it for Gu Lianyan. You don't care about human life, you are just trying to please her, that's why you are a good person. Why are you holding yourself back for a woman who doesn't love you?"

The Duan Chengxuan in her impression of killing was decisive, putting life on the scales to weigh it.

But now, Duan Chengxuan was willing to give up the throne that was easily obtainable for the sake of Gu Liuyan, and he even had to endure it for this reason.

What kind of bewitching soup did Gu Liuyan give you?

"We were different to begin with." Duan Chengxuan slowly stood up and looked down at her from above. "Even though I am ruthless and cruel, I am Navy Tide's imperial family member from the beginning to end. Even if I regard my life as worthless, the responsibility of the imperial family still rests on my shoulders."

In the end, Su Yuwan's expression changed and she looked at him in disbelief, "Big Brother Xuan, have you forgotten what the emperor and empress dowager did in the past? They took away the throne that should have belonged to you, and also took away your freedom, so they imposed these responsibilities on you.

The man in front of him halted his steps, a bloodthirsty smile on his face.

Cheng Shan, who was at the entrance, lowered his head even lower. Su Yu Wan only felt a black shadow flash before her eyes. Duan Chengxuan's hand had already fiercely grabbed her chin and nearly crushed it.

"You will only make me remember hatred, but Yan'Er is different."

"She taught me how to do my duty, how to love someone."
