No matter what, Lu Zhe had gone from having nothing to possessing a complete set of primitive tools.
The sharp dinner knife, small round blades, fish spears, stone axes, slingshots, stone mortars and stone knives were extremely arduous to make, but would play a very important role in surviving later on.
Looking up at the sky, it was already afternoon. Lu Zhe hastily ate something, when the system sent him a task, "Find three kinds of advanced natural cleaning supplies! Reward: +6 potential points!"
Advanced natural...hygiene products?
That's right, bamboo leaves can be used as toilet paper! That should work!
He would let Shen Bing continue making mosquito repellent.
He decided to take a stroll through the bamboo grove himself to get some bamboo leaves, and bring back some bamboo to improve the campsite at the same time.
Lu Zhe chopped down seven or eight bamboo poles and a bundle of leaves, tying them together to carry back to the campsite!
Sure enough, he heard the system reward sound.
Just then, he discovered a small creature squatting not far away!
Looking closely, it turned out to be a bamboo rat!
This was delicious game!
It could provide the human body with large amounts of protein and amino acids!
He quietly took down the slingshot and loaded a pellet!
At that moment, the little creature keenly sensed the danger and scurried away in a flash!
Lu Zhe didn't want to give up and quickly chased after it. After chasing it for over thirty meters, the bamboo rat slipped into its burrow in a flash!
Lu Zhe felt a tinge of regret!
But he was more happy than regretful!
The meat reserves were still sufficient for now. It got away this time, but as long as this species existed on the island, it would end up on the menu sooner or later!
He was about to head back!
Just then, a prompt sounded in his mind, "Ding! Important resource discovered, Chinese pistache!"
Looking up, he saw a big red-barked tree not far away!
He was rather curious and walked over.
Lightly touching the Chinese pistache bark, information about it immediately appeared in his mind!
Lu Zhe was overjoyed!
It turned out this tree was the legendary "toothbrush tree"!
This tree had a wide global distribution, and many African and Indian natives used its branches to clean their teeth!
Because the resin contained fluorides, chewing it to make white foam could strengthen and whiten the teeth!
This was also why many black people had such white teeth!
Lu Zhe broke off a branch.
"Ding! Obtained the second kind of advanced hygiene product, +2 potential points!"
He had already found two kinds!
Were there any others?
Lu Zhe searched the vicinity again for a long time, but didn't find a third hygiene product.
Carrying the bamboo and leaves, holding the pistache branch, he returned to camp.
By this time, the other girls at camp were also awake. Seeing Lu Zhe had brought back a large pile of things again, they hurried over to take a look.
"Wow, Lu Zhe, what other good things did you find!"
Lu Zhe put down his things, "I found substitutes for commonly used items in life!"
Shen Bing picked up a bamboo leaf, "I know, bamboo leaves can be used to brew tea, which clears heat and promotes diuresis, treating kidney deficiency!"
Then Shen Bing smiled meaningfully, "But why'd you grab so many, do you need to replenish that much?"
"This is..."
Lu Zhe smiled wryly, "What you said isn't wrong, but I took so many because they have a more important function!"
"What function?"
"We're out of toilet paper, dried bamboo leaves are a relatively safe substitute. They have no irritation to the skin, the downside is they're a bit narrow, the texture is a bit lacking. Before we find a more suitable replacement, we can use them as toilet paper."
Lu Zhe paused and added, "Of course, you can also use them to brew tea if you want."
Shen Bing froze, "I don't have any desire to do that now!"
Tang Xiaoguo picked up a leaf and felt it, "So narrow, your hand would get dirty right?"
Lin Qianqian nodded, "Don't be picky now, Xiaoguo, having something is better than nothing!"
Ning Shu gave a thumbs up, "Practical, I approve!"
Jiang Yao picked one up to look, "I bet the bamboo didn't expect its leaves to be used for this! Oh right, what's this branch, it looks nice."
Lu Zhe took out a pistache branch, "This is our toothbrush!"
"Toothbrush?"
The girls looked at each other, Tang Xiaoguo blinked, "How does it look anything like a toothbrush!"
"It's a pistache branch! Africans and Indians use it to brush their teeth!"
As he spoke, Lu Zhe tore off a piece and chewed the end, turning it into a brush shape!
"What about toothpaste then?"
Lu Zhe picked up a piece of charcoal from next to the fire pit, crushed it into powder with a rock, then smeared the grit on his teeth!
"Charcoal is a natural cleaning agent for teeth!"
Seeing the black froth foaming up in Lu Zhe's mouth, Shen Bing and the girls were shocked!
Shen Bing said, "Even if charcoal has absorbency, is cleaning like this really hygienic?"
"Yeah, it looks really gross!"
"I'm traumatized now!"
"If you keep doing this, I won't share a water bottle with you anymore!"
"It just looks a little dirty! Charcoal that's been through fire doesn't even have microbes or bacteria, it's the most sanitary cleanser. Just don't brush too long each time, it can damage the gums!"
Three minutes later, Lu Zhe had brushed the inside and outside of his teeth thoroughly with the pistache brush. It felt about right!
He drank a sip of coconut water, forcefully puffed his cheeks, swished the water around to rinse off the carbon grit from his teeth, then spat it out!
Now his teeth looked exceptionally clean and white!
Lin Qianqian was amazed, "Wow, it really works!"
"Of course, do you want to try it out?"
As he spoke, Lu Zhe held out the pistache branch to the girls, who all unconsciously shrank back.
"What, you don't want to brush your teeth?"
Ning Shu said, "The effect does seem good, but the charcoal is a bit hard to accept!"
"Of course, you don't have to try it if you don't want to! Even if you don't brush your teeth it won't affect survival, it'll just make your teeth yellow after a few weeks, then grow tartar, and after a few months you'll have teeth like coffee!"
"Ah?" The girls were shocked!
"Oh no, I won't be able to face coffee anymore!"
Still, Shen Bing took the branch first, "I think it's necessary to try it out!"
Following along, she also chewed a section of the pistache branch, then took some charcoal from the fire pit, crushed it and smeared it on her teeth!
Mimicking Lu Zhe, she swished and spit!
As if by magic, her teeth also became exceptionally bright and white!
Simply more effective than real toothpaste.
The other girls were envious!
After all, in the nine days of surviving here, they worried about fresh water and food every day without time to clean their own teeth!
And chewing gum could only temporarily remove debris between teeth, not fixing the root issue, plus they didn't have much left!
It seemed that to maintain a bright set of teeth, they had no choice but to do this!
Seeing the elegant, beautiful lady cop do it, what more was there for them girls to fuss over?
Following the same steps of chewing the branch and smearing charcoal, then rinsing with water!
Finally chewing some mint leaves,
their teeth also became bright and white, their breath fresh and clean!
Look, this is the right way for young girls to shine!
Just then, Lu Zhe discovered the stone mortar he had just made was placed by the fire pit, still holding water.
"What's going on here?"
Tang Xiaoguo smiled bashfully, "Cooking something!"
"This is a stone mortar!"
"I know that! Trying out new ways, seeing if it can work as a pot! But..."
Tang Xiaoguo crouched down, "After boiling for so long, how come the water isn't boiling yet?"
Ning Shu looked at it too, "I knew it wouldn't work. The mouth is too small, can't use too big a fire. The stone walls are too thick, the heat dissipates before it can transfer inside."
"Looks like we still can't drink soup."
Shen Bing smiled gently, "It's not that we can't drink it, I have a way. Like this it will work..."
As she spoke, she used a stick to pick up a small rock from the fire pit and tossed it in.
"Hiss..." The water inside immediately started boiling.
