That's right, Su Jinli is planning to make trouble again!

She herself is idle, and in ancient times, she had no Internet, and she couldn't watch TV series to pass the time.

Su Jinli sat bored for a while, and when she went to solve her personal problems, she suddenly found a very serious problem-

She, she, she...... It's time for a period!

It's embarrassing.

Although there are a lot of hygiene products stored in her space, there is a very real problem in front of her.

Even if she can use it secretly, where will she throw it away after she finishes using it?

Thrown outside the space can't be explained, thrown in the space...... That's disgusting!

Su Jinli had no choice but to call Duofu with a red face and ask Duofu to help her get the "necessary supplies".

Duofu quickly fetched a small strap and a roll of white cloth.

Su Jinli looked at the things in her hand in a daze, and thought about it desperately for a while, and finally found the relevant memory.

She endured it, and used it according to her memory first.

After solving the problem in front of her, she immediately went to the study, took out a pen and paper and began to write.

She had heard that women in old times used a cloth strap that could be tied around their waists, and when they were used, they were padded with toilet paper or plant ash.

Even in the new era, in some particularly poor places, there are still people who use this.

She hasn't had her period since she crossed over, and she actually forgot such an important thing, so she is in a hurry now.

Toilet paper!

Toilet paper must be made!

Su Jinli recalled the papermaking process, and secretly found a reference book from the space and began to refer to it.

The grandfather who adopted her liked to read books and read miscellaneous.

After the old man died, all the books belonged to her.

They are all the brains of the old man, and she is reluctant to throw them away, so they exist in the space.

Now it's where it comes in handy.

Su Jinli thought happily, quickly found the content he needed, and quickly copied it.

After copying, she was about to send someone to call Zhou Pan, but suddenly her mind moved, and she thought of a question: Since she wants to make paper, why don't she solve the bathroom problem together?

Her current bathroom was definitely luxurious in ancient times, but compared to the flush toilet, it was unsightly.

She just crossed over some time ago, and even if she disliked it, she didn't dare to change it immediately, for fear of being found out that she was an impostor.

As a result, I was busy tossing and turning things around, but I forgot about such an important thing as the toilet!

This is absolutely unbearable!

Su Jinli hurriedly found a book and began to draw the toilet.

She bought the book herself because she had to renovate her house and ended up having a hard time choosing which toilet to choose.

She bought a book about various types of toilets, looked at the principles, and saw which one was better.

With books, things are much simpler.

Su Jinli began to draw the structural design of the toilet on paper.

This is just a matter of drawing from the picture in the book.

But after the design was drawn, there was another problem.

In ancient times, there was no running water, so you have to pay attention to the water inlet and drain of this toilet.

If you want to use a flushing toilet, you must have a steady stream of water.

And where should the sewage be discharged?

It's definitely not okay to just disem it indiscriminately, so you have to have a place to dispose of it.

So, there had to be a sewage well, and there had to be a reservoir for water.

The sewage well must be located outdoors in a remote place, or a public toilet should be built and connected to the public toilet.

Usually close it with a lid and open it again when you clean it.

Every day in the city, people come to collect the night incense, so this sewage well can be cleaned once a day.

In this way, there is basically no smell.

However, in order to connect the indoor toilet to the public toilet, it is necessary to install underground sewage pipes.

The tubes can be made of ceramic, and the joints are bonded with an adhesive, such as cement......

Wait, shouldn't she burn the cement out together?

The toilet bowl should also be made of ceramic, and the lid and the middle backing plate can be made of wood.

In this way, it is better for her to buy a ceramic kiln factory.

Su Jinli was suddenly entangled.

Where did she get all that money?

To make toilet paper, you have to have a paper mill.

It all costs money!

Su Jinli suddenly felt that her head was big, so she thought of Chu Yan, the king of Qin.

She has no money, but Chu Yan, as a prince, is always rich, right?

Flush toilet is a fetish, who uses it and who likes.

As long as it is made, there is absolutely no worry about not being able to sell.

And toilet paper, too.

With such two big businesses, if the Su family wants to run it alone, it is easy to attract people's eyes.

Or Laqin King partnership is more safe.

Su Jinli thought about it and decided to ask Chu Yan to borrow money to try it first.

If Chu Yan picks the door and refuses to borrow it, she will kick this goods and find a new partner!

In the Qinzheng Palace, Chu Yan, who was listening to the quarrel between the courtiers, suddenly sneezed loudly.

"Ahh

Suddenly, the entire Qinzheng Hall was quiet.

Everyone looked at Chu Yan in astonishment.

Even Emperor Yong'an was shocked.

He was listening impatiently, who knew that his son actually gave him this play.

As a good father, Emperor Yong'an still cares about his body.

He frowned and looked at Chu Yan worriedly: "Are you infected with wind and cold?" ”

Chu Yan looked confused.

He practiced martial arts all year round, was physically strong, and almost never got sick.

Cold?

Inexistent.

So the question is, since he didn't have a cold, why did he suddenly sneeze just now?

Could it be that someone is scolding him behind his back?

Chu Yan was about to say, "The ministers are fine", when he suddenly saw the courtiers.

So his face changed slightly, and the words he said also became: "Erchen is indeed a little unwell, maybe because he didn't rest well last night, Erchen begged his father to allow Erchen to return to the palace to recuperate." ”

It's really annoying that these people are arguing around, and he might as well go back to the palace to "recuperate".

Emperor Yong'an was about to agree, but when he saw his ruddy face, he suddenly felt cheating.

So he said: "The wind and cold are not a trivial matter, so I will announce the imperial doctor." ”

Chu Yan: "......"

Afraid of revealing his stuff, he hurriedly said: "Father doesn't have to work hard to mobilize the people, the son is just a little unwell, it's not a big problem, go back and sleep and it'll be fine." ”

Emperor Yong'an's face sank: "Since it's not a big deal, you can listen to it here!" ”

I know you bastard wants to be lazy!

Chu Yan: "......"

Ministers: "......"

What does this mean, Your Majesty?

Unexpectedly, King Qin was deliberately left!

Could it be ...... Is His Majesty's favorite person really the King of Qin?

But the crown prince has not made a big mistake, does His Majesty want to abolish the prince?

After some brain fixing, everyone's heads are bigger.

……

After Su Jinli finished drawing the drawings, he quickly wrote a letter to Chu Yan, and then called Ping'an, and specially explained: "Ping'an, you personally go on a trip, hand over the letter to Zhou Pan, and let him pass it on to King Qin." And told him that after the king of Qin read the letter, he would come directly to me. ”

Ping An looked at Su Jinli in surprise, and his eyes widened: "Girl, you ...... You actually wrote a letter directly to King Qin? ”

Is this a private gift?
