After transmigrating into the book, I replaced the innocent-looking girl and became the Crown Prince

When Qingwen arrived at Biyunting, Wu Weiwei had not yet returned.

According to the maid, Wu Weiwei seemed to have accompanied the young master to Butterfly Valley.

Qingwen clutched her handkerchief tightly, her heart filled with hatred.

Because of the matter concerning the young lady, the young master has been in a very bad mood these past few days.

Unexpectedly, that vixen Wu Weiwei was able to coax the prince into forgetting his sorrows and keep him company at all times.

She should have told Lady Hou about her search for the iron box earlier.

She shifted the blame for the lady's suspicions onto Wu Weiwei.

It's unclear how Wu Weiwei learned the truth that her cousin was not dead.

Wanqiu watched as Qingwen's face turned from red to white, then from white to green, and wondered if there was something wrong with her health.

So he kindly asked, "Qingwen, you look so pale, are you feeling unwell?"

Reminded by Wanqiu, Qingwen immediately adjusted her mindset.

"I'm fine, I'm just worried that the Lady of the Marquis will blame your concubine."

"Really? But that's what the young master asked for, and our aunt couldn't refuse."

Even so, Wanqiu knew that going to Butterfly Valley was Wu Weiwei's idea.

But she would never tell Qingwen about her aunt's plans.

"is it?"

Qingwen gave her a cold look.

"Well, our aunt is just the prince's concubine. How could she possibly dictate his thoughts?"

Hmph, I doubt she has that ability.

"When your aunt returns, tell her that the Lady of the Marquis is looking for her and asks her to come to Qiushui Pavilion."

"Understood, Sister Qingwen."

Butterfly Valley Manor.

As Wu Weiwei watched Min Wang leave with several young masters, she was thinking about how to find his business expert.

Ling Fu watched as Wu Weiwei gazed longingly at Min Wang's figure.

Concerned, she called out, "Auntie, although the young master is a bit cold and has a bad temper, I can see that he has been very fond of you these days."

As for that Prince Min, I've heard he's a promiscuous prince with an unpredictable temper.

He takes his anger out on women at the drop of a hat, and is a dissolute prince who only knows how to eat, drink, be merry and do bad things.

He's nowhere near as good as our Crown Prince.

Wu Weiwei turned her head and looked at Ling Fu with amusement.

"Lingfu, who said I have feelings for Prince Min?"

Someone like him makes me sick to even look at him.

She was merely going through the motions with Prince Min, secretly hoping to poach one of his capable subordinates.

"Oh, you're not interested in Prince Min?"

Lingfu was embarrassed.

It turns out I was overthinking it.

However, if Aunt Wu doesn't like him, why did she agree to go to his manor the day after tomorrow?

Lingfu couldn't figure it out, but since she couldn't figure it out, she decided not to think about it anymore, as it was a waste of her brainpower.

The two waited for a while.

Finally, I met Liuyun, who had rushed over and was covered in dust.

Liu Yun stepped down from the sedan chair and explained, "The young master just left and sent me to fetch you. I apologize for keeping Aunt Wu waiting."

"leave?"

Wu Weiwei frowned.

"Oh, the young master has received an urgent business trip and may be away for a while."

Liu Yun touched his head, thinking that what the young master was about to do was not something that Aunt Wu should know.

So he hastily made up an excuse to brush her off.

Hehe, it's probably not official business, but rather a trip to Tongzhou to find the female lead!

However, Wu Weiwei did not expose Liu Yun.

The people in the Marquis's mansion will find out about this sooner or later; it's just a matter of time.

With Ling Fu's help, Wu Weiwei got into the sedan chair and pretended to be asleep the whole way back.

Just as they arrived at the entrance of the Marquis's residence, they saw Chen Caiyun about to leave.

"Sister Chen, are you going out?"

"Hello, Aunt Wu. I'm just about to go out and buy some raw materials to make donkey-hide gelatin cakes."

Chen Caiyun was able to get a job in the Marquis's mansion without being harassed, thanks to Wu Weiwei.

Therefore, Chen Caiyun felt grateful to Wu Weiwei.

Donkey-hide gelatin cake?

Sister Chen's donkey-hide gelatin cake is absolutely amazing; it's incredibly nourishing for women.

Wu Weiwei thought for a moment and realized that the noblewomen of the Great Wei Dynasty did not have any concept of health preservation, and there were very few health supplements available.

She remembered that the female lead opened a medicinal cuisine restaurant in the capital with the help of the crown prince.

Although the female lead has medical skills, she mostly relies on Sister Chen for her money-making ideas.

Using Sister Chen's beauty-enhancing and blood-nourishing donkey-hide gelatin cake as a gimmick, she befriended many wealthy women in Beijing, gaining both social connections and making a fortune.

The female protagonist has not yet been tempered by life to the point of being able to see through people's hearts, nor does she possess the business acumen that comes with experience.

Why not take advantage of the fact that she hasn't figured it out yet and win at the starting line?

Speaking of this, she recalled that when she was a flight attendant in modern times, she had the good fortune to meet the son of a pharmaceutical tycoon.

The two chatted happily and passionately throughout the night at the hotel.

As they parted, the second-generation doctor said he had nothing to give her in return, so he told her about a beauty secret from his family.

At the time, she just thought it was a joke.

Later, she jokingly told her younger boyfriend about the secret recipe.

It's worth noting that one of her younger boyfriends is a senior R&D engineer at a small pharmaceutical company.

He studied the secret formula for a long time, but ultimately gave up due to a lack of human and financial support from the company.

However, the younger boyfriend held a positive opinion about the pharmacological effects of this secret recipe.

Could she perhaps give this beauty secret to Sister Chen for her to study?

If she could develop it, wouldn't she be able to profit from it?

Thinking of this, Wu Weiwei said to her, "Sister Chen, after you finish buying the materials, could you please come to Biyunting? I have something to talk to you about."

"No problem, I was just thinking of making some donkey-hide gelatin paste and sending it to you, Auntie."

"Well, then I'll thank you in advance."

Wu Weiwei smiled.

Upon returning to Biyunting, they heard Polly happily say, "Greetings, Auntie! Greetings, Auntie!"

Wu Wei's mother gently tapped Polly's head. "You have such a sweet tongue. Are you thinking about the delicious treats I brought you?"

"Clever aunt, clever aunt..."

Wu Weiwei looked at Lingfu behind her, "What a greedy bird, give it to her!"

Lingfu laughed heartily, unpacked the pastries she had brought back, and took out a shortbread from inside.

"Here, eat!"

"Thank you, Auntie, thank you, dear Fufu!"

Lingfu: "..."

Wan Xin: "..."

Wu Weiwei couldn't help but laugh out loud.

Unexpectedly, Poli has now added Lingfu to the list of people he likes.

“Aunt, Qingwen came by an hour ago and said that the Lady of the Marquis wants you to come over.”

Everyone in the household is saying that their concubine is a stand-in for their cousin. If the cousin were to return, their concubine might…

Wanqiu looked at Wu Weiwei with concern.

"Auntie, is the young lady about to be brought back by the young master?"

Seeing this, Lingfu couldn't help but ask with concern.

Wu Weiwei looked at the lush weeds growing next to the orchids in the yard.

"What are you worried about? She may be an orchid, but I am a resilient weed that never fights back. The one who laughs last is the winner."

"That's right, our aunt is a hundred times prettier than our cousin. What do you mean by 'student double'? How do our aunt and cousin look alike?"

Although Lingfu had never met her cousin, she had heard from the elders of the Marquis's mansion that her cousin was not as beautiful as her aunt.

Wanqiu nodded. As long as their master was open-minded, they had nothing to fear.

Who cares if she's a cousin or not? Her mistress is already a concubine.

If she gives birth to another child for the heir apparent in the future, then her concubine can simply enjoy her life.
