Transmigrated into a farmer's lucky charm, all the villains in the family panicked.

Yun Shengsheng is now the Princess of Jinrong County, and the Emperor has bestowed upon her a multitude of rewards.

Furthermore, the entire Yun family knew about the 100,000 taels she had dug up from the estate herself, making Yun Shengsheng the wealthiest person in the family.

The family members were all happy, not jealous.

No one would think she was too young to help her keep it safe or use it.

Even her mother, Gan Yuwan, only reminded her to keep the money safe.

Gan Yuwan thought that if her little girl needed anything, she would help her with that.

Yun Shengsheng found the silver troublesome, so she handed it all over to Yan Shijin and asked him to exchange it for silver notes of different denominations, which she then threw into her spatial storage.

She also threw in the jewelry, headdresses, and other precious items that the emperor had bestowed upon her.

Anyway, one cubic meter of space is equivalent to three large suitcases side by side. If they are stacked neatly, they can hold quite a lot of things.

After that, Yun Shengsheng started to act spoiled and ask for leave in front of Yan Shijin again.

As the saying goes, "He who takes a man's money is bound to do his bidding," and Yan Shijin, having benefited from Yun Shengsheng's generosity, also earned 100,000 taels of silver, so naturally he couldn't refuse.

"But Sheng Sheng, you can't keep skipping school forever, can you?"

Actually, he didn't want to go, but as long as Sheng Sheng was there, he felt it wouldn't hurt to go.

"How could that be!"

Yun Shengsheng rolled her eyes inwardly.

I'd like to stay away from it forever, but is it really my decision? Sigh, I'm just a pitiful ordinary citizen; how can I possibly fight against the powerful?

Yan Shijin's lips twitched, and he remained silent in his heart.

Has the little girl forgotten that she is now a county princess of the second rank? Even the noble ladies of first-rank officials have to bow to her.

Yun Shengsheng had no idea what he was thinking. She grabbed his arm and started acting cute.

"Brother Shi Jin, Brother Shi Jin, you're the best, please approve my leave request."

"See, I'm not slacking off; I have important things to do."

"Think about it, I'm going to open a printing factory, specializing in printing books. Think about how expensive books are these days. A poor student has to save up for half a year to buy one book. But isn't it true that the more books the better? So buying one a year is practically useless."

"But if we print our own books and lower the prices, wouldn't everyone in the world be able to afford them?"

Yan Shijin naturally understood this principle.

But I still think the little girl is going to great lengths to avoid going to the academy.

He knew beforehand that she was going to open a printing factory, but the plan was that it wouldn't open for several months.

But now it's happened earlier than expected.

It's easy to imagine that he wouldn't want to go to the academy even for a single day.

Jin hesitated when she saw the banquet.

Yun Shengsheng simply plopped down next to him.

Mo Ning watched from the side, her eyes immediately widening.

Ugh, I really want to pick this little girl up and throw her out.

You've squeezed into our master's space, don't you know that?

Has the concept of hierarchy been lost?

Looking at his master's pathetic state, instead of telling the little girl to get out of the way, he blushed and quickly moved to the side.

Mourning sulked, panting, and finally turned away.

Yun Shengsheng ignored Mo Ning's erratic behavior and continued to hold onto Yan Shijin's sleeve, swaying and shaking it in various ways.

"Brother Shi Jin, think about it. Which is more important: me studying alone, or all the poor students in the world being able to study?"

"Isn't it more important for everyone in the world to study?"

"Besides, I'm still young, and I'm especially smart, so it won't hurt to focus on my studies for a while!"

"Actually, I'm not suited to going to the academy to study every day; I'm suited to the credit system."

Yan Shijin raised an eyebrow: "What is a credit system?"

Hooked.

Yun Shengsheng was secretly delighted, but put on a serious expression.

"It means setting up credits for all the required courses."

"For example, if each course is worth 100 points, I can stop studying once I get 100 points."

"You don't need to worry about how long it took me, right?"

"A less intelligent student might need a year to learn to get 100 points, but if I can learn it in three months, then I only need to study for three months. The rest of the time is my own, and I can allocate it as I please."

"This is how you learn efficiently."

"Instead of keeping people confined in the academy every day, forcing them to learn when they can't, it's a waste of time."

"Also, just take the exam when it's time. If the exam results are all fine, there's really no need to confine the exceptionally smart people."

Yan Shijin remained silent.

It wasn't because her words were particularly eloquent, but because what she said actually made sense.

He recalled that he had died at the age of sixteen in his previous life, but he hadn't missed out on anything he was supposed to learn.

Now that he has been reborn, many of the things he is learning at the academy are things he already mastered in his previous life.

Sitting in class every day listening to content that you already know by heart is indeed repetitive and meaningless.

However, the academic subjects he truly needed time to study and the layouts he needed to plan were squeezed out by the academy's schedule.

Perhaps it's not just Yun Shengsheng who needs this "credit system," he needs it too.

Yan Shijin had an idea in mind, but he didn't want the little girl to get too cocky.

"So, how long does Sheng Sheng plan to take leave this time?"

As soon as Yun Shengsheng saw that things were loosening, she immediately raised a finger.

Yan Shijin raised an eyebrow, his tone clearly teasing: "A month?"

Yun Shengsheng coughed lightly: "Um... is a year possible?"

Yan Shijin narrowed his eyes.

Yun Shengsheng immediately realized something was wrong and quickly tried to fix it.

"Brother Shi Jin, do you know why book prices keep going down? It's simply because paper is too expensive."

"With paper production costs remaining high, the paper that booksellers get is already ridiculously expensive. When they then have it written into books, the price naturally can't come down."

"So it's not enough for me to simply set up a printing plant; I also have to remake the paper. I need to use a new process to make paper that is both cheap and good."

"First, reduce the cost of paper, and then add printing technology, so that book prices can be reduced to a level that anyone who can afford to eat can afford to buy books."

She paused, her tone shifting from the calmness of a business plan to a quiet, private conversation.

"Moreover, once the new paper is made, it can not only be used to print books. It can also be used... um... to replace bamboo mats for wiping your bottom!"

Yan Shijin froze for a moment.

He looked at Yun Shengsheng with a complex expression.

Of course he knew that this girl had been secretly wiping her bottom with toilet paper for the past two years.

The entire Yun family knew, but no one said it out loud.

It was as if, in a silent way, her habit, which transcended time, was being indulged.

Yun Shengsheng herself was actually quite guilty, because paper was expensive and hard, and it was also uncomfortable to sit on.

She felt like she was rubbing her buttocks with gold every day.

But she had no choice; she couldn't just refuse to poop...
