Traveling through ancient times: Savages are hungry for food

Not long after Sang Tian returned to the cave, Lan came with a dozen females and sat around the table.

It's not that Sang Tian didn't want to call others, it's just that this cave is too small to accommodate them...

Sang Tian did have something very important to teach them today, and it was aimed at females.

A woman's menstrual period occurs approximately every 30-40 years of her life, and it's crucial for her health. It's absolutely crucial not to be careless.

Sang Tian: Which little handsome guy is saying why don’t you hold back your period when it comes?!

May I ask?

In fact, after these few days, Sang Tian sometimes noticed that some females' menstrual blood would flow down their inner thighs when they were collecting...

Particularly fastidious females would immediately go to the side and get an animal hide to clean up the mess as soon as they felt it, but most of them would only feel it when the menstrual blood was flowing down their legs, and then they would immediately take out the animal hide to wipe it off...

Sang Tian is a woman like them, she can only empathize with them, not laugh at them!

Whenever Sang Tian accidentally saw this situation, she would usually lower her head and pretend not to see it out of respect.

She didn't look down on them, nor did she laugh at them... Sang Tian only worried deeply about them and felt sorry for them...

If you don't take any precautions during your menstrual period and wait for it to flow out before dealing with it, how much trouble would it be if it happened so many times a day?

Moreover, exposure to the air, especially during the menstrual period, poses a high risk of infection...

Sang Tian would also feel deeply depressed by the low living standards of this era, but at the same time it aroused Sang Tian's will to change this era.

"I've said before that I'm determined to nurture the seeds of humanity in this ancient and barbaric land... This journey probably began on my first day here, and perhaps it will only end on the day I die..."

Although Sang Tian has a bug that allows him to use sanitary napkins infinitely, there are so many females in this tribe, and there will be more in the future. Does Sang Tian have to give them sanitary napkins every time a female has her menstrual period?

This is simply not feasible!

Besides, although sanitary napkins are common necessities in modern life, here... they are probably like alien objects... If you give them away easily, there is no guarantee that someone with ulterior motives will use them to cause trouble for Sang Tian or the Tianlang Tribe.

After all, my bag is so small, where do all those sanitary napkins come from? How can I explain it to myself?

……

Besides, Sang Tian sent the weapons when it was a life-or-death situation, and only about forty people were sent out.

And she won't give them away randomly in the future. She will only give them out as rewards to those who have made great contributions to the tribe...

……

Besides, what Sang Tian wants is to teach them how to live a good life, rather than using modern things to make their lives better.

What Sang Tian wants is the development of primitive civilization, not its mutation...

……

Sang Tian has been keeping this in mind these days, and has been paying attention to the available materials on the way to the collection team.

Sang Tian is not a god, and he cannot make high-polymer water-absorbent sanitary napkins in this ancient wilderness where no one lives.

But the simple version is always okay! Although it is not as good as the modern one, at least it won’t make their menstrual period so messy...

Sang Tian has been keeping an eye out for cotton these days, but unfortunately, he hasn't seen any trace of it...

But Sang Tian found wild cotton.

Wild cotton also has medicinal value, treating injuries from falls, rheumatic joint pain, ascariasis, etc.

Wild cotton begins to produce cotton in the fall. The cotton is beige in color and feels rough and has small particles. However, this does not affect its ability to absorb water.

How could they not be excited when they heard that Sang Tian was going to teach them how to make sunflower belts?

When Lan and others arrived, they had already collected the wild cotton impatiently.

The outermost layer that comes into contact with the skin is naturally animal hide.

However, Sang Tian currently thinks that the only feasible options are deerskin and rabbit fur. These two types of fur are light, thin and soft, and neither stuffy nor hard on the skin.

Sang Tian folded a piece of animal skin in half and used bone scissors to cut out the shape of a modern sanitary napkin.

First, place a layer of compacted wild cotton on a piece of animal skin sanitary napkin, then sprinkle an appropriate amount of plant ash on it. Then place another layer of wild cotton on the plant ash.

The inside of the animal skin wrapping consists of these three layers.

Then put another layer of animal skin on top and sew them together tightly.

……

Wood ash is also the main water-absorbing material besides wild cotton.

Although wood ash looks dirty, it actually does not contain bacteria, etc.

Because wood ash is calcined at high temperature, the entire calcination process is a disinfection process and does not contain bacteria and pests.

Furthermore, wood ash can be used as a disinfectant. For example, applying wood ash to wounds can help inhibit bacterial infection. Sprinkling wood ash around plants not only improves fertility but also kills pests and bacteria.

In the 1920s and 1930s, wood ash was used to make sanitary napkins, and it was even commonly used in ancient times. It can be considered an ancient method.

Of course, sanitary napkins are used on important parts of the body, so carelessness is not an option. Therefore, when calcining, it is important to ensure that the raw materials, calcination ground, and equipment are clean.

In order to prevent the wood ash powder from floating out, Sang Tian specially set up two lines of defense.

The first layer is naturally wild cotton. The wild cotton is all pressed firmly and spread on the wood ash in a full layer, which can also effectively prevent the wood ash powder from flying around.

The second layer is naturally animal hide, with the fat side of the hide located inside the sanitary napkin. It has a high density and small gaps, which can effectively suppress plant ash powder.

When changing sanitary napkins, you open them and throw away the ash and cotton inside. These are all disposable. However, animal skins are reusable. They are washed and exposed to the sun every time they are changed.

When you use it next time, fill it with wood ash and cotton and sew it up again.

So you have to do more at a time; one or two won't do the trick.

……

This will naturally not make it light and thin enough, and the water absorption effect will not even reach medium.

But this is the best Sang Tian can do.

It is indeed troublesome, but at least for them, it is a rare good thing.

It's much better than the previous situation where they had no facilities and just let their menstrual blood flow.

……

If you have sanitary napkins, you naturally need underwear, otherwise what should you do?

Sang Tian drew the shape of the underwear again and asked Duo to make it.

"Wow, San. This shape is quite suitable. And you said that the size can be adjusted according to individual body shapes. At night, it can be made into the shape of the underwear you just drew. This is so convenient!"

"My period is only a few days away, so I'll give it a try then. It's definitely better than nothing at all!"

"That's right, San. What you taught me is really practical. It will make our daily lives more convenient! Thank you so much!"

"Thank you, San..."

The voices echoed in Sang Tian's ears. Sang Tian could only smile shyly and be polite.

……

That concludes today's tutorial.

Lan said that she would then take these dozen people to teach other females.

The group thanked each other politely and left in an orderly manner.

……

It was already late in the evening, and Sang Tian walked out of the cave to get some fresh air and some fresh air.

Only after coming out did I realize that I was too immersed in the teaching just now.

I didn't even notice when the hunting team came back...
