The royal family reads her mind, and the cannon fodder daughter creates the Feihou Mansion

"Madam, there is no need to be so formal with me. Just call me Yunxi."

Madam Zhu followed suit: "Yunxi, I will never forget your life-saving grace."

"This is the blessing that Madam has accumulated through her good deeds. Even if there is no blessing, I will have someone else to help you."

Fortunately, she was able to save Madam Zhu in this life, and Song Yunxi felt sincerely happy.

After instructing Madam Zhu not to reveal any clues and alert the enemy, Song Yunxi left the Taifu Mansion.

After returning to the Imperial Master's Mansion, he went straight into the pharmacy.

Reagents were taken out from the space to test the petals and soil samples brought back, and it turned out that they contained cold poison ingredients.

But Song Yunxi had never seen this kind of cold poison. She looked through all the books in the Imperial Master's Mansion before she learned from an ancient book that this cold poison actually came from a poisonous herb called cold marrow grass that is unique to South Vietnam.

Cold marrow grass only grows in the miasma forests of South Vietnam. It absorbs the damp and cold air of the miasma to grow. As the name suggests, its cold poison can invade the bone marrow and kill people invisibly.

Even the people of Nanyue, who were good at using poison, regarded this poisonous weed as a deadly weed and dared not touch it. Even the miasma forest where it grew was considered a forbidden area. Unexpectedly, it would appear in the inner house of the Taifu Mansion.

The orchid was obviously grown with the venom of the cold marrow grass, so it has a fragrance different from ordinary flowers and plants, and that fragrance is difficult for ordinary people to detect.

But Mrs. Zhu, who has been growing flowers for many years and knows a lot about flowers, can smell it.

Being able to grow orchids with cold marrow grass, Song Yunxi asked himself that he would not be able to do it even if he was reincarnated again. It can be imagined how powerful the person who used the poison must be.

But Madam Zhu was just a woman in the inner court. Even before she got married, she was an ordinary girl. Why did they go to such great lengths to take her life?

Since she couldn't figure it out anyway, Song Yunxi stopped thinking about it for the time being.

I took the ancient books and went to Qin Xubai's yard.

Because Qin Xubai needs long-term recuperation due to health reasons, his courtyard is a unique side courtyard far away from the main courtyard. It is full of bamboos, which is very consistent with his elegant and refined temperament.

In the yard, Qin Xubai and Ji Ziche were playing chess, while Jiang Yanting fell asleep on a rattan chair while holding a ferret.

"Diao'er, come here!"

The snow ferret, which was originally lazily lying in Jiang Yanting's arms, immediately became energetic when it heard Song Yunxi's voice, and jumped into Song Yunxi's arms with full energy.

Stroking its snow-white body, he said, "Diao'er is so good."

Looking at the bright and beautiful girl glittering in the sun, Qin Xu's eyes were doting: "The emperor wants you to enter the palace?"

Song Yunxi looked disgusted: "Who knows what bad ideas he is planning."

If the foolish emperor dared to use her to get his eldest brother, she would ensure that the Ye family would be cuckolded for generations.

Ji Ziche smiled helplessly: "Although my uncle is confused and narrow-minded, he has complete trust in Master. Even if it is for Master, he will definitely not plot against you."

Song Yunxi raised her chin proudly: "It's better to be like this, otherwise I don't mind letting his Ye family change hands."

Qin Xubai leaned over and stroked the ferret in her arms: "If he dares to let you suffer any injustice, just overthrow his harem, don't have to worry about anything."

Even if the truth is revealed, don't we still have the Imperial Master's Mansion and Shengyun Mountain to protect us?

Ji Ziche: “…”

Senior Brother, is it really okay for you to teach her like this?

Although his uncle, the emperor, was a little cheap, he was still a legitimate emperor after all.

Song Yunxi smiled innocently, "Don't worry, big brother. If he dares to set his sights on me, I will fill his harem with men and weld the green hat onto his head!"

Ji Ziche: “…”

Hey, I'm still here! He's my uncle after all, so please stay away from me.

Inside the Chongzheng Hall of the Imperial Palace, Emperor Qinglong couldn't stop sneezing one after another. Sun Huigong worriedly ordered someone to call the imperial physician.

There was frost in Qin Xubai's lowered eyes. He had followed the Qin family's ancestral precepts, and now the sacrifice of the entire Qin family was enough!

His aunt's life was ruined, and his life has been returned to the Ye family. Having escaped death, he will only seek revenge for the rest of his life!

Song Yunxi placed the ferret on his lap and took out the ancient book from his sleeve: "Brother, do you know if there are people in Nanyue... or in our Jin'an Dynasty who are good at using cold marrow grass to poison people?"

When Qin Xu heard about the cold marrow grass, his handsome face turned serious: "Why are you suddenly interested in the cold marrow grass?"

Song Yunxi did not hide anything and told Madam Zhu that she had been infected with a cold poison.

"No wonder I didn't find any signs of poisoning when I took her pulse before. I just thought it was caused by her eating cold food for many years."

The cold poison of the cold marrow grass is no different from the condition of a cold body. If she hadn't discovered the orchid that was cultivated by the venom of the cold marrow grass, even she wouldn't have been able to discover it.

Qin Xubai's expression became more and more solemn: "Although the cold marrow grass grows in South Vietnam, and the people of South Vietnam are also very good at using poison, but there has never been a person in the entire South Vietnam who can control the cold marrow grass."

Song Yunxi frowned slightly, it was just as she thought.

He made a bold guess: "The person who can use the cold marrow grass can't be from our Jin'an, right?"

Although it was a question, she was very sure of her guess.

Qin Xubai nodded: "Indeed, he is from Jin'an."

Who would have thought that the poisonous weeds that even the people of Nanyue could not conquer would be used by the people of Jin'an to harm others.

"Brother, do you know who it is? Could it be them who did it?"

Qin Xubai shook his head with a gloomy expression: "Impossible, the people who knew how to use the cold marrow grass, the entire clan has died."

The last piece between Qin Xu's fingers fell on the chessboard to end the game: "The only people in this world who can use the cold marrow grass are the royal family of the previous dynasty, and they have long been exterminated and slaughtered."

The royal family of the previous dynasty came from the Wei clan on the southwestern border. They were a family of alchemists and were also extremely skilled in the use of poison.

When the world was in chaos, the Wei clan emerged to take advantage of the chaos and wanted to get a piece of the pie.

Having no wealth or military power, they relied on secret drugs to control and manipulate human nature. They used this underhanded method to eliminate various overlords and unify the Central Plains.

But the Wei family knew that they were not strong enough to win the support of the people, and they were also worried that the throne they had obtained through schemes would be unstable, so they became more obsessed with refining and making various secret medicines, using these secret medicines to eliminate dissidents and consolidate the imperial power.

They tested the poison on captured soldiers and civilians displaced by the war, and successfully refined a cold poison from the cold marrow grass.

I didn't expect that the previous dynasty had such a secret. I have no good feelings towards Song Yunxi, a member of the royal family of the Wei family who used dark and despicable means.

Ji Ziche's icy expression also looked solemn: "I have heard my mother talk about the things of the previous dynasty. At that time, Emperor Taizu led his army to fight and was invincible along the way. After conquering the capital, the first thing he did was to kill all the remnants of the previous dynasty to eliminate future troubles."

Ji Ziche was puzzled: "All the members of the Wei family died, why did the cold marrow grass poison appear?"

Song Yunxi murmured lightly: "That doesn't necessarily mean they are all dead."
