Island sanitary Napkin

That material certainly won't work!

Compared to sparrow sister, he now has better quality material: sponge!

With it as the main material, plus charcoal and cotton cloth, it might work to try it!

Just have to wait until the sponge is completely dead before using it, living sponges wriggle, and the feeling of those little bugs crawling around and about would surely drive the girls crazy?!

Even if they don't go crazy, Lu Zhe himself wouldn't allow it!

That's a sacred inviolable place!

Except for himself, he absolutely won't allow any living creatures to get near it!

Uh...

Went off topic!

In fact, sponges fished out will quickly die!

Then become dry and hard.

After soaking in water they become soft again.

So its properties are the opposite of a certain spongy substance.

If it maintains a certain humidity, it will stay soft and supple.

Before finding a better alternative, it's perfectly fine to try using it!

But using it directly, there would still be bacteria and microorganisms, easily disrupting the pH balance down there for the girls!

Once the steady pH balance is disrupted, the delicate aroma of a maiden could disappear, giving off the smell of a middle-aged woman.

Just imagining a few girls as beautiful as flowers giving off the smell of middle-aged women, Lu Zhe felt his whole body go wrong!

No, the microorganisms and bacteria must be gotten rid of!

So what specifically should be done?

The simplest method is boiling water?

No, that won't work either!

Although high temperatures can kill bacteria and microorganisms, at the same time it would also destroy the internal structure of the sponge, boiling it to mush.

Lu Zhe has already thought of a way!

That is the famous "pasteurization"!

Sounds very high-end, but the actual principle is very simple!

The specific method is to maintain a temperature between 50 and 60 degrees Celsius for thirty minutes, which can kill 99% of bacteria in food, without destroying the original nutrition and texture of the food.

Sterilized eggs and milk usually use this method for disinfecting.

The effect is really nice!

So what should be used to maintain a fixed temperature?

That's right, it's the stone mortar!

This is the third way Lu Zhe thought of to open the stone mortar — pasteurization!

Lu Zhe started working on it.

First make a small grill, control the flame size, then put the stone mortar on and boil coconut water, the low heat is insufficient to fully penetrate the thick stone mortar walls, but can keep the water inside the mortar at a constant temperature for a long time!

After boiling for a while, Lu Zhe tested the water temperature with his hand, feeling it slightly scalding, but not hot enough to burn his mouth when sipping some.

That's right, this is about 60 degrees Celsius!

After waiting a bit longer, testing again, still the same temperature!

This is it!

Next, put some sponges into the stone mortar, set a timer on his watch, 30 minutes.

At this time, also don't be idle, he started looking for other materials.

There were several old clothes picked up in his backpack.

One cartoon tank top, pure cotton, with some damage in one place.

Judging by the size it should be a young girl's, maybe the mother threw it away because it was damaged.

It can be used to wrap around the sponge and charcoal.

The small clothing is not afraid of high temperatures, boil it in boiled water from a can and sun dry it thoroughly.

After thirty minutes, take out the sponges.

By now the sponges were already long dead, and the bacteria and microorganisms had also been eliminated for the most part.

Although it would be more effective to rapidly cool after disinfecting, there was no way to do that now, so this would have to do.

Squeezing them, still very elastic!

However sponges that are too soft placed between the legs definitely wouldn't feel very comfortable, in order to give the girls the most perfect experience, they need to be made a little thinner!

But cutting them into thin slices would also affect their absorbency!

No problem!

Lu Zhe got some charcoal. Put between two slices of sponge, to enhance the absorbency!

Then cut the little girl's clothes into strips about 20cm long, tightly wrapping the sponge and charcoal inside!

This can ensure absorbency, and not be too thick to wear comfortably.

Put inside briefs, it can perfectly play its role!

Lu Zhe made five sets!

Should be enough for now.

At the same time, neither Jiang Yao nor Tang Xiaoguo had used the last sanitary pad.

From the initial disagreement, to later concession, to now brainstorming together, they were all exploring one question:

How to get by in the days without sanitary pads!

Some said use dry grass, some said use cloth, some said wash with seawater each time, and some said just leaving them unwashed wasn't a big deal.

But on careful thought, none of those were reliable!

And just then, Lu Zhe returned to camp.

Seeing Lu Zhe arrive, they lowered their heads and didn't speak.

After all, it was still very embarrassing for guys to know about girls' troubles.

But they underestimated Lu Zhe's directness:

"What's wrong, because you're running out of sanitary pads?"

Both girls' faces turned red.

Lin Qianqian sighed, "Although that may be so, still feels a little strange being asked directly by a guy."

"No problem, it's resolved."

"How did you resolve it?"

Lu Zhe presented his masterpiece: "Use this!"

Ning Shu blinked her eyes: "This is... what exactly?"

"Lu Zhe's proprietary secret recipe, island version sanitary pads!"

Ning Shu was petrified, then yelled out loud: "Why... would you make something like this!"

The other girls also widened their eyes: "Yeah, too weird!"

"It's for you guys!"

Lu Zhe said proudly: "After all girls have more trouble, as the only guy on the team it's my duty to help you solve your current problems, you should be happy about it!"

The four girls looked at each other speechlessly!

Happy about what, their whole bodies felt wrong!

Shen Bing awkwardly took it and squeezed it: "Oh, it does seem kind of like the real thing, what did you make it from?"

"Disinfected sponge, charcoal, materials with very strong absorbency, plus disinfected pure cotton underwear, can effectively absorb water, and won't have bad effects on delicate skin down there. More importantly, the cloth acts as briefs that can be disinfected each time, reused, only needing to replace the sponge and charcoal inside. Clean and hygienic, comfortable during daytime activities, doesn't leak when turning at night, definitely thoughtful and intimate protection for you!"

After he finished talking, the girls' jaws dropped, all rendered utterly speechless.

Tang Xiaoguo said: "Little Lu Zhe, are you serious?"

"Of course!"

Ning Shu gaped in astonishment: "Lu Zhe, don't tell me you learned this from The Why as well!"

"This..." Lu Zhe wanted to make up another reason again, but really couldn't think of one, so he nodded:

"Yes!"

"Tell me which version of The Why would teach stuff like this?"

"That's not important! The key is it really can resolve the problems you'll face in the future. Even if we had ten packs, it'd quickly run out right."

"You're... not wrong..."

"But having a guy explain this kind of thing to us, makes a girl feel totally wrong."

"Forget it, Lu Zhe isn't an outsider!"

Shen Bing was a bit resigned, but she also understood, if they stayed on the deserted island for long, these were issues they would inevitably have to face sooner or later.

She squeezed it again, feeling the softness and comfort weren't bad!

A thought arose in her heart, looks simple but this thing might really be able to resolve their big problem coming up!
