On this day, Li Chengqian arranged some matters in the East Palace.

didn't want to, but Wu Zetian came to look for him again.

Li Chengqian thought to himself: Didn't this Wu Zetian go to the queen's bedroom early in the morning, why did he come to my East Palace again after a while? No, she should go to accompany the queen.

I saw Wu Zetian in a hurry.

"I've seen His Royal Highness the Crown Prince!"

Li Chengqian took a closer look, and Wu Zetian's face was a little pale.

"Wu Jue, your face doesn't seem to be good, what's the matter?"

Wu Zetian then said:

"That's right, when I went to the queen's bed this morning, I saw that the queen's face was pale, and I saw many people coming in and out, holding the ashes of plants and trees in their hands, and they didn't know what to do.

I asked Her Royal Highness the Queen, and she didn't say anything, just bed rest, and asked me to go back first, I felt sick, and I was worried that something was wrong with her, so I ......"

"So, you come to the East Palace to find this king! I hope this king can ask and help you solve it? ”

Wu Zetian couldn't stop nodding.

"His Royal Highness the Crown Prince is really very smart, and he guessed what Wu Jue was thinking at a glance."

The grass and trees are gray, and the face is not good......

This is simple, it must be the queen to come to the eldest aunt.

In ancient times, women would use hay or sponges to solve problems during menstruation, because they found that these things were better absorbed, and hay was everywhere and easy to find. But obviously, hay or sponges have a big problem, that is, they are very unhygienic, not to mention that they are easy to breed bacteria, these things themselves carry bacteria, and they have not been sterilized, so they are very unsafe.

With the development of civilization, there are more and more kinds of things in people's hands, so women began to use linen as a sanitary napkin, so that only the linen cloth needs to be cleaned, which is much cleaner and safer than hay. However, in the Tang Dynasty, a more convenient "menstrual belt" was invented.

The menstrual belt is actually a long and narrow belt made of cloth, and then filled with plant ash in the middle. The menstrual belt is carried on the body when the menstrual period comes, so it is much more convenient and easier to clean than using linen directly.

The matter of the eldest aunt is a very painful thing for many girls, compared to now, ancient women are really sinful.

In the feudal era, people thought that the eldest aunt was a very unfortunate thing, even if she was the queen, the eldest grandson queen could only hide in the room and dare not come out. So I excused myself in the room and didn't go to meet Wu Zetian.

This made Wu Zetian think that something had happened to Empress Changsun, so he came to ask for help.

This girl is not bad-hearted, but she also cares about the eldest grandson queen very much.

From this point of view, Empress Eldest Sun really didn't hurt her in vain.

Li Chengqian was thinking in his heart that he was patronizing the invention of other things, and he could forget about this thing.

Women are half the sky, if that thing is invented, it can alleviate the embarrassment of being a woman, and it can make them less invasive of gynecological diseases. And it can be freed from the bed, no matter how you move, it will not be affected. If it is extended to the private sector, it will undoubtedly increase the labor force for society.

Otherwise, half of the people in the entire Datang are women, and it will be a big loss to have a few days every month when they can't work.

So this thing is also a big business opportunity!

Then next, he is going to invent sanitary napkins, which can be said to be a great invention and a great product of the times of caring for women.

"Wu Jue, your chance to make meritorious service has come."

"His Royal Highness the Prince, Wu Jue just came to let you think of a way, why did you give me the opportunity to make meritorious contributions? It's very puzzling! ”

Wu Zetian is still young now, and he doesn't know that there is such a thing as a woman, so naturally he can't understand the pain.

"You wait!"

Li Chengqian then took some cotton and drew a piece of paper for the maids, and asked them to sew it into a cloth bag in the shape of an aunt's towel in later generations.

Wu Zetian was dazzled on the side, and he didn't know why.

In particular, she didn't know what that strange shape was for.

Wu Zetian also knows how to be a female celebrity, she has been watching it for a long time, but she still can't see why.

Many people worked together to quickly complete three strange things.

Li Chengqian didn't pick it up, but directly asked the maid to hand it over to Wu Zetiandao: "These things, if you hand them over to Her Royal Highness the Empress, she will definitely be happy!" ”

Wu Zetian faced these strange things in front of him, and suddenly felt very puzzled.

"But this has nothing to do with Her Royal Highness's illness at all."

"This little girl is really ...... Not easy to explain. ”

And he can't send it over directly, after all, it's something used by women, how can he do such a thing as a prince?

If you really send it over, I'm afraid it will make people laugh.

But Wu Zetian is different, she is a woman, but she can do this.

Such an obvious opportunity to make meritorious contributions, and to improve her status and make her more favored, why not do it?

Speaking of this, Wu Zetian still didn't understand.

"But Her Royal Highness the Queen, she ......"

"Believe me, go!"

Li Chengqian's firm expression directly infected Wu Zetian.

"Okay, I'll give it a try."

Wu Zetian was just about to go out, and then came back.

"Can I really give this thing to Her Highness the Queen? What if she asks? ”

"You say, this thing can replace the effect of plant ash!"

Wu Zetian was ignorant.

"Really?"

"Is it necessary for this king to lie to you?"

Li Chengqian said angrily

"Wu Jue didn't mean that, just curious, does Her Royal Highness really know?"

"Go ahead and do it."

"Yes!"

"Remember, it is said that this thing can relieve the inconvenience, and you thought of it, and you must not say that it was the king's idea. This king can't afford to lose this face. ”

Wu Zetian was said to be stunned, how could he be embarrassed, and he didn't ask anything more specifically, and left the East Palace directly.

This Wu Zetian can be regarded as his own person, even if the invention is in her name, it will be fertile and waterless to outsiders.

"Good! Then she went to try it, hoping it really worked. ”

She was still a little apprehensive in her heart, after all, this kind of thing might not really work well in her opinion.

She walked outside and turned back again.

"If Her Royal Highness the Queen asks, then what is the use of this thing?"

"This thing is called a menstrual belt! After use, it can be cleaned and used repeatedly......"

Since this is the case, then Li Chengqian explained some precautions for this thing.

After listening to it, the ignorant Wu Zetian probably understood what was going on.

"In this way, Jue'er went to find Her Royal Highness, hoping to relieve her some pain."

"Go ahead!"
