It was better to strike first and question Duan Chengxuan. This way, he would be able to dispel the doubts he had towards himself.

On the other side, feigning jealousy would not only allow Duan Chengxuan to connect this matter to the Mirage, but would also make Duan Chengxuan remember him.

"In the end, as long as the vast majority of people think that this poison was administered by Duan Chengxuan, then everything will be fine."

The corner of Gu Daiyan's mouth lifted slightly. In one hand, he held the date mud cake, while in the other, he handed two small paper bags and a letter to the ghost: "Go and secretly send them to the Second Prince's courtyard."

"I was sneaking a peek at you, but I didn't see that the Prince suspected you." The ghost carefully put the item away.

"His personality is suspicious. If I didn't say that this is my poison, then do you believe that Chengshan would have secretly come here to search for my formula? If he were to be found out by then, he might not believe me for eternity." Gu Danyan smiled and even made a bet with ghost to see if Chengshan would come back for the formula tonight.

After settling this issue, Gu Danyan still wanted to go to the Hall of Relief to help, but he found that things had more or less been resolved. The doctors didn't want her to work hard and just told her to go back.

As soon as she sat in the carriage, she instructed the coachman, "Go to the Prime Minister's Estate."

The coachman was troubled. "But the prince said that he wanted to have dinner with you. In the afternoon, he will make a trip to the palace."

When he thought about it carefully, he realized that he had been acting jealous just now and had pretended to misunderstand him when he left. It was probably not good to be overly enthusiastic about the past now.

"I have an even more important matter to discuss with the Prime Minister."

"Yes." The driver stealthily turned his head to peek inside before changing his direction.

Arriving at the Prime Minister's residence, Gu Danyan found Gu Cheng in his study room. Gu Cheng seemed to be worrying about some matters, and his expression didn't look too good when he saw Gu Liuyan.

"I want to go worship my mother." Gu Liuyan cut straight to the point: "But I don't want to know her story, I don't think this request is too much."

After a moment of silence, Gu Cheng waited for his reaction before putting down the things in his hands, "Have you heard of something?"

"They don't seem to talk about it."

"They did the right thing. You don't need to know about this. Your mother is not in the ancestral hall or the ancestral tombs. She is not worthy of being worshipped by a grand Crown Princess like you." Gu Cheng's expression softened.

He suddenly grabbed Gu Daiyan's hand like a good father and pulled her to a chair to the side. "She will only bring you gossip."

Facing Gu Cheng's sudden warmth, Gu Pingyan's expression remained the same, "I've come across quite a bit of gossip. Even if you hadn't told me, I could have found it with the help of the Prince's men."

"Who taught you to threaten your father?" Gu Cheng's expression instantly darkened. Compared to before, it was as if he was a completely different person.

"Of course, I can also tell the prince about the child in the stomach of the Scholar." Gu Danyan laughed lightly: "I have long since stopped treating you as my father. However, you only received eight thousand taels of silver last month and sold off the official position of the government official in Huzhou. Your daughter has already sold off quite a number of official positions for you."

Gu Cheng's expression changed as he became angry, "Someone, bring the Miss to pay her respects to Madam Yun!"

"Thank you, father." Gu Daiyan laughed heartily.

On the outskirts of the city, there was a mountain called Shadow Mountain. At the foot of the mountain, there was a small village.

As for Yun Wan's tombstone, it was located halfway up the mountain, while Gu Cheng's abandoned courtyard was located at the foot of the mountain. It had three to four courtyards and the decorations within were extremely exquisite.

Gu Pingyan dismissed all the servants and carried the ghost up the mountain.

There were no roads on the mountain, so passersby would take a detour.

It is said that there is a ghost lady who climbed out of the water and wandered around the dark mountain. As a result, many poisonous insects and plants grow here and because this ghost lady likes to transform into a young woman to absorb the essence of a man, no one else would dare to come up. All I know is that this place is always foggy and is prone to poisoning. The ghost said in a low voice.

"It's strange that the father has set up his own courtyard here." Gu Danyan was holding the hands of a ghost. Although she had learnt some martial arts, the mountain path of the Shadow Mountain was really strange.

"This is the Soul Suppressing Residence, which is given to the Prime Minister by the late emperor. The meaning is for the Prime Minister to serve the country, watch over the Heaven Flame, and protect the safety of the people. Also, this Soul Suppressing Residence lives and dies with the Prime Minister, and if one day the Prime Minister is disloyal and disloyal, he will send someone to flatten the Soul Suppressing Residence and send the Ghost Wife to seek his life." The ghostly book began to talk, and he pulled Gu Danyan to his side.

"The late emperor was rather interesting." Gu Pingyan was panting. He glanced at the mountain road and asked curiously: "But tell me, how did Father get someone to bring my mother's coffin up here?"

"It should have been lifted by a rope. I'm afraid I didn't want to disturb your mother's peace and quiet, so I found a place like this."

Gu Liuyan sighed and pouted: "Why do I feel like you all think that my father loves my mother so much?"

"Of course, although no one brought it up again in the city, your mother Yun Dian is a famous beauty. She was also like you, holding on to the lifeline of the imperial court at that time, and it was also like that as well. In the end, the Prime Minister had no choice but to lock her up here after she pitied someone and eloped, afraid that she would leak out the secret." The ghost continued to reply.

Gu Liuyan was speechless. She had not expected that Gu Cheng would actually hide things that everyone else knew from her.

Halfway up the mountain, there was a piece of ground that had obviously been dug up by someone. Yun Wan's grave was right here, where the ground had been cleaned up. There were quite a few weeds beside the tombstone.

Gu Danyan helplessly poured two cups of green plum wine he had bought earlier and placed them in front of the tombstone. He then carefully arranged the pastries he liked and gently placed them in front of the tombstone.

The ghost took the knife from his waist and tried to clean up the weeds.

However, Gu Liuyan stopped him: "Don't disturb my mother. This grass looks pretty good."

With that, Gu Liuyan spread a layer of blue cloth on the ground and kowtowed three times before the tombstone. She folded the blue cloth and placed it in front of the tombstone, and said in a low voice: "Daughter likes to drink green plum wine, and also likes to eat date paste cake cloud cake. Daughter's favorite color is water blue jade green, I have been happy for my whole life, but I have disgraced my mother's beauty …"

After chatting for a while, before Gu Tinyan left, she stopped talking and lowered her head to look at the tombstone filled with weeds. She said softly, "If mother sees Bai Mi or the rhinoceros in the underworld, please pass on a message for Yan'Er."

"In your next life, send yourself to a good family. In this life, it's your father who has let you down. Your mother will personally make your father pay."
