A wicked mother swaps her son and sucks his blood? The true legitimate daughter is reborn and goes o

The Prince's Mansion, front hall.

Last night, Xie Yunli sent the renowned doctor he had found to Fazong Temple and did not return home overnight.

Upon returning home, he heard that Rou'an had come back. He had been waiting in the front hall. When the brother and sister met, they were both overjoyed and excited.

"You've lost weight." Xie Yunli looked Xie Rouan up and down carefully, feeling both heartache and relief.

Rou'an was pampered since childhood, and her originally fair skin has become a bit darker, but the frankness in her eyes has not diminished, and her eyes are much brighter than before.

"My brother has changed too."

Xie Rouan naturally knew what her brother and the Prince's Mansion had gone through during this time.

The mother and her two sons tacitly avoided mentioning Prince Yu.

"Brother, I went to many places this time. I stopped to paint wherever I went, and I even drew a map." Xie Rouan talked about what she had seen and heard along the way, and instructed a maid to bring a booklet, which she showed to Xie Yunli as if it were a treasure.

The booklet contained a map of the mountains and rivers of Dajing, and every part of it was much more detailed than any existing map.

"I used to only want to paint the landscape of Dajing, but now, brother, I want to finish painting the map of Dajing and present it to Fourth Brother." Xie Rouan's eyes seemed to be shining.

To complete the map of Dajing, one must traverse every corner of Dajing.

The journey must have been arduous, as you can imagine.

Princess Yu hesitated, unable to express the heartache she wanted to convey.

Thinking of the painting from that night, she already had Yunli under her control, so she couldn't keep Rou'an trapped as well.

She supports whatever she wants to do, but her simple nature is a cause for concern.

And that brother and sister...

"Rou'an, whatever you want to do, just do it. Your brother will protect you for life." Xie Yunli's eyes were full of doting affection.

Outside the door, Su Ling only heard this voice and was certain that Xie Yunli was an exceptional person.

Protecting Xie Rou'an for life...

Xie Rouan is truly blessed.

If only I had woken up as Xie Rouan.

And this Xie Rouan...

Su Ling scoffed at her "grand ambitions".

With such a privileged background, she was born into a life of endless wealth and luxury, yet she insisted on "traveling," enduring hardships along the way, all for the sake of drawing those lousy landscapes and maps.

Asking for trouble is extremely foolish.

Su Ling scoffed inwardly, but in an instant, she changed to a self-reproachful and naive demeanor, entered the hall, and knelt on the ground.

"Sister Rou..."

Sobbing followed immediately.

In the hall, the family of three looked over together, and when they saw Su Ling, Princess Yu immediately frowned.

Xie Rouan also frowned, but her expression showed concern.

"Ling'er, what are you doing?" Xie Rouan stepped forward to help her up.

But Su Ling didn't get up. She looked up, her face full of genuine and sincere self-reproach.

"Sister Rou, Ling'er was wrong. Ling'er has been learning medicine from her master on the mountain since she was a child. She doesn't know the rules of the world. She shouldn't have taken it upon herself to go to the palace with you out of curiosity, which made things difficult for you. It's all Ling'er's fault."

Because of their mutual support along the way, Xie Rouan was very tolerant of Su Ling. "I know, and I don't blame you. You don't need to blame yourself. You're new to the capital and don't know the rules. How about this..."

"I'll have your nanny teach you some basic etiquette and manners, so you won't accidentally bump into someone and get hurt when you go out."

Xie Rouan was wholeheartedly thinking of Su Ling.

Su Ling resisted in her heart; she didn't want to learn any etiquette or rules.

But at that moment, the old princess was looking at her, and Prince Li's gaze was also on her. She wanted to make a good impression.

Not only can you not refuse, you also have to act obedient and compliant.

"Really? Ling'er is willing to learn." Su Ling blinked her bright eyes and nodded happily.

With her naive and innocent demeanor, if it weren't for her actions this morning that aroused the Princess Consort of Yu's suspicion, she would have been fooled as well.

This woman is cunning, a good actress, and had helped Rou'an before. She and Rou'an had gone through many hardships together, so it's no wonder that Rou'an was deceived by her.

Princess Consort Yu did not say much.

However, her occasional lapses in vigilance displeased Su Ling, causing her to hesitate to act rashly in front of Xie Yunli.

Xie Rouan gave the two a brief introduction, and Su Ling then returned to her courtyard.

On the way, I overheard the maids talking:

"The old princess is looking for a wife for the prince. In the past few days, she has collected portraits of many daughters of noble families. I wonder which daughter will become our princess."

"Anyone worthy of our prince must be of excellent appearance and upbringing."

"Of course, the old princess attaches great importance to it. I just heard from the head maid that a flower appreciation banquet should be held to invite the young ladies to gather together, so that the prince can choose one that suits his taste."

"Wouldn't that be just like the old princess's birthday celebration before...?"

"Let's not end up like on the old princess's birthday, when she almost got into trouble. Luckily, Consort Song saved her, otherwise..."

The maids' voices faded into the distance.

Su Ling's face immediately paled.

Is the old princess going to choose a princess for Xie Yunli?

This won't do!

Having just seen Xie Yunli in person, with his handsome features and gentle demeanor, she was absolutely the male lead, which made her even more certain that Xie Yunli was the true love that God had arranged for her.

She hadn't even had a chance to use her charms, and the old princess was already choosing a wife for him?!

Su Ling felt even more disgusted with the old princess.

She's destined to be Xie Yunli's princess.

A life of wealth and glory, a life of luxury and privilege, is within reach. She cannot allow an old, aging "future mother-in-law" to become an obstacle in her path.

We need to find a way!

Suddenly, the maid's words, "The old princess almost got into trouble that day, but fortunately Lady Song saved her," popped into my mind.

Su Ling's eyes lit up. "Something's happened, someone's in trouble... If I become that old hag's savior, not only will she thank me, but her son will also look at me with new respect. Wouldn't that be killing two birds with one stone?"

Making that old geezer "get into trouble" would be too easy for her.

The original owner of this body studied medicine for ten years.

Medicine and poison are interconnected; all her skills now belong to her.

Su Ling took a stroll around the backyard and quickly found something ready-made that could cause "trouble" for the old princess.

And the "Empress Song" mentioned by the maid...

Su Ling had heard too much about Song Qingning along the way. Xie Rouan spoke of her with admiration and affection, and others praised her in every way.

She was said to be a female general who protected the country, and that she was both a woman of great literary and military talent, and was deeply loved by the new emperor.

Su Ling didn't take it to heart.

He believed himself to be chosen by fate. He was an ancient person who must have used some means to gain the new emperor's favor and was good at putting on a good image for himself.

She'll have to meet her when she gets the chance, tear off her disguise, and expose her true colors.

Su Ling thought to herself.

Inside Jinhua Palace.

Song Qingning slept until night.

On the soft couch, Song Qingning kept her eyes closed and remained unconscious.

Beside him, Xie Xuanjin looked solemn.

"Her Majesty has not yet woken up?" Xie Xuanjin lowered his voice, sensing something was amiss, but also afraid of disturbing Song Qingning.

Hongling also realized something was amiss. "Your Majesty, Her Highness fell asleep after the banquet and did not even have dinner. I tried to wake her, but I could not."

"Your Highness, what's wrong with her?"

Hongling felt uneasy.
