After swapping bodies with the princess, this prince slaughtered his way through the court and becam

After Wei Xinyan returned to Hanzhang Palace.

Suddenly, the maid Zhu'er brought over a bowl of hawthorn and brown sugar water.

"Princess, you should drink some hawthorn and brown sugar water."

Ren Jingxing was immediately stunned.

"Hawthorn and brown sugar water? Why would I drink that?"

Pearl was also stunned:

"Princess, have you forgotten?"

Your period is approaching. Drinking hawthorn and brown sugar water before it starts can relieve your abdominal pain.

Ren Jingxing blinked, shocked.

Tiankui? Isn't that just menstruation?

Wei Xinyan's menstrual period occurred when the two souls swapped?

Ren Jingxing suddenly felt a bit of a headache, even though he didn't feel it right now.

"Can drinking this relieve the pain?"

The maid, Zhu'er, nodded:

"Yes, Tiankui drank hawthorn and brown sugar water before, and brown sugar and ginger water when she had her period, and both of these helped relieve the pain!"

Ren Jingxing frowned more and more as he listened.

"Does it hurt a lot when you have your period?"

Pearl nodded vigorously:

"Princess, you're in so much pain! You're always so pale. Pearl is so worried about you!"

hiss……

Ren Jingxing gasped.

So, he not only wants to help Wei Xinyan ascend to the throne as Empress, but also to help her fight menstrual cramps?

Isn't this appropriate?

Ren Jingxing quickly opened the Empress's Training Record, hoping to see if it contained any methods to treat menstrual cramps.

Unfortunately, no changes were observed on the ancient scroll.

It seems he can only rely on himself...

Ren Jingxing couldn't help but mutter.

He does have a way to keep Wei Xinyan safe for ten months.

However, this method is quite difficult, as it requires a face-to-face meeting.

Moreover, the treatment process is somewhat erotic, and the consequences are quite serious.

This future empress, outwardly weak but inwardly somewhat stubborn, may not necessarily agree.

Hey……

Ren Jingxing sighed.

Before he could figure out how to treat his menstrual cramps, he needed to figure out how to get through his period.

"What did I need to do when I came for my period before?"

The little maid, Zhu'er, pouted.

She discovered that when the princess became irritable, her memory also declined significantly.

Perhaps this is a kind of illness, or perhaps it's because the princess suffered too much before.

Pearl felt sorry for her princess and then took Wei Xinyan's menstrual blood bag.

These are two strips of coarse cotton cloth that have been washed until they are faded.

It is one foot long and about three inches wide.

After folding the strip of cloth in half, sew it together on three sides, leaving one side open, to make a flat, long cloth bag.

Following the method suggested by the maid Zhu'er.

Before her period, she would go to the Imperial Kitchen to get dry, fine wood ash from the kitchen.

Then pour the wood ash into the pocket of the menstrual belt and sew it up.

Every half day or after soaking, open the cloth bag and pour out the blood-soaked wood ash.

Wash repeatedly with clean water until the water runs clear, then reuse.

After it dries, refill it with new mortar, sew it up, and set it aside for later use.

A single piece of cloth often takes three to five years to use.

They mended and patched the fabric until it was too tattered to hold any more dust.

Sometimes, due to difficulties or unexpected heavy rain, it was impossible to retrieve the ash from the Imperial Kitchen.

Wei Xinyan would also choose to burn some firewood and collect ashes in the Hanlu Hall.

Or you could simply find some dry soil, sift out the fine particles, and put them into your menstrual pad.

This was the first time Ren Jingxing felt a pang of sadness for Wei Xinyan.

A princess of such high status, yet she is so poor and destitute.

"And you, Pearl? Are you the same way?"

Pearl nodded as if it were the most natural thing in the world.

In fact, all the palace maids at the bottom of the harem of the Great Wei Dynasty came from this background.

In fact, this applies to all women at the bottom of society in the Great Wei Dynasty.

Ren Jingxing patted Zhu'er's head affectionately:

"Don't worry, it won't be that difficult in the future."

The menstrual belt was simply too outrageous; Ren Jingxing couldn't handle it.

He decided to create sanitary napkins.

Perhaps this could even help supplement Wei Xinyan's household expenses in the palace.

"Pearl, take out all the old, worn-out cotton clothes we've worn over the years and take them apart!"

Pearl blinked and asked in confusion:

"Oh, so what should we wear?"

Ren Jingxing flicked Zhu'er on the forehead:

"I've already been given a title, why should I still wear old clothes?"

And those four little maids, bring out all their old clothes, cut them into strips, and put them in new clothes!

Pearl was both excited and heartbroken.

I'm excited to wear new clothes, but heartbroken to have to cut up the old ones.

In fact, sanitary napkins do not necessarily have to be old clothes.

However, old clothes are often washed until they turn white and lose their starch.

This kind of fabric won't chafe your skin when it's close to your skin.

After preparing the close-fitting fabric, the next step is the most important absorbent layer.

Wood ash is indeed useful, and the effect is quite good.

Ren Jingxing planned to continue using wood ash, but not just wood ash.

He wanted to add cotton and straw paper to both sides of the wood ash.

The straw paper was neither the yellow Xuan paper used before death, nor the lowest quality coarse paper.

Instead, it's the slightly more expensive white cotton paper sold in the shop.

Several sheets stacked together have similar absorbency to wood ash, and most importantly, they are clean.

You can throw the whole stack away after you're done using it.

But if all of them were made of this kind of paper, it would be too expensive.

Ren Jingxing planned to use two layers of folded white cotton paper, with wood ash in the innermost layer and cotton in the very middle.

The bottom layer consists of two layers of oil paper, specifically designed to prevent leaks.

After these layers are compressed, its absorbency exceeds that of overnight sanitary napkins.

To prevent it from falling off, Ren Jingxing decided to use a menstrual belt as an aid.

The fabric was secured by sewing straps onto both layers.

Looking at the final product, Ren Jingxing still had some concerns.

The last few months have been alright, but wouldn't it be unbearably hot in the summer?

After the finished product was completed, the little maid Zhu'er looked at the small cloth bag with curiosity and asked in confusion:

"Princess, what is this?"

Ren Jingxing weighed it in his hand and said:

"This is called a sanitary napkin. It's a disposable menstrual pad that's more convenient and comfortable than the old ones."

Pearl blinked, looking surprised.

"So the princess can do this too."

She thought her princess only knew how to study and fight.

The following evening, Ren Jingxing brought his homemade sanitary napkins with him.

On the morning of the third day, Ren Jingxing was woken up by the pain.

"Holy crap..."

Ren Jingxing couldn't help but curse.

He remembered the last time he cursed someone was when he hit Granny Li from the laundry department.

Ren Jingxing had heard that some women experience severe menstrual cramps, but he never expected Wei Xinyan to be in so much pain!

He felt as if his lower abdomen had turned into a wet wad of cotton, sinking heavily downwards.

I also felt as if there was an invisible hand in my abdomen, gripping my internal organs and twisting them incessantly.

The strangest thing is that this pain is not only limited to the lower abdomen, but also spreads downwards.

My lower back felt sore and heavy, as if it were broken, and my thighs were also weak and sore.

He felt that even standing up straight was difficult, and he just wanted to curl up in a ball.

In addition to pain, there is also dizziness, nausea, and cold hands and feet.

"Damn it, this won't do, I have to find a way!"

Ren Jingxing didn't know how Wei Xinyan had managed to hold on, but he knew he couldn't take it anymore.

He remembered the methods he had seen online before he traveled through time.
