After all, if you can't even live, how can you think so much.

Now that living conditions are better, and the problems of food, drink, housing and transportation have been solved, we must pay attention to hygiene.

This is also a social problem. If it is not properly improved, it will cause a series of chain reactions.

Yue Qinlan nodded and said, "Then we need to promote toothbrushes and charcoal powder."

Mu Liang thought about it and said, "The cleaning power of charcoal powder is suitable for the simplest cleaning, but not suitable for teeth with diseases. It needs to be improved."

"How to improve?" Yue Qinlan asked curiously.

"This will give Yuffie a headache." Mu Liang smiled.

He wanted to make an ointment that could add herbs to enhance its cleansing power.

Mu Liang has ideas and understands the ancient method of making toothpaste on the earth, but the practice still depends on Yuffie. After all, she knows more about herbs. Yue Qinlan asked softly, "What about toothbrushes, mass-produced as we usually use?"

"That would be too slow for mass production." Mu Liang shook his head again.

The toothbrushes used in the palace are all made of beast hair and colored glass, which are highly similar to the toothbrushes of the earth, and even have better bristles.

If you want to mass-produce toothbrushes, toothbrushes made of glass are obviously not suitable, which requires special cooperation of glass beasts, and the efficiency is too low.

"Then what should I do?" Yue Qinlan wondered.

"Go and ask Xiaolan to find a piece of wood and animal hair." Mu Liang said in a clear voice.

"Okay." Yue Qinlan stood up and left the study.

Not long after, Wei Youlan walked into the study and placed the wood and animal hair found in front of Mu Liang.

"How?" Yue Qinlan blinked her water blue eyes.

"It's very simple. Use sticky spider silk to fix one end of the animal hair, and then fix it on the wood. That's it."

Mu Liang moved while talking, using spider silk to stick the animal hair together, and then fix it on a finger-thick wood.

He snapped off the excess wood and tried to rub the head of the toothbrush with his hands.

The animal hair is very sticky, and the animal hair can only be pulled off by pulling it hard.

"...It's really simple." Yue Qinlan covered her mouth and said gracefully.

"Just do it, remember to degrease the animal hair before using it for mass production." Mu Liang reminded.

Degreasing the animal hair is to soak the animal fur with grass and wood ash water, and remove the oil on it, which can eliminate the fishy smell on the fur.

"I see." Yue Qinlan responded.

765: Mutants with first horns. (3 more)

High in the sky, the oasis is moving at a constant speed.

On the third floor of the oasis, the fox fairy was sitting lazily on the animal skin chair, holding a few cards in her hand.

Opposite her, Hu Xi and Charlotte sat on both sides, holding a few cards in their hands.

The time to rush to the oasis is boring, so the three girls get together to play landlords and kill time.

"Sister Fox Fairy, it's your turn to play the cards." Charlotte said crisply.

The fox fairy raised her eyes to look at the orange-haired girl and the orange-haired girl, her rose-red eyes flashing, recalling what cards the two girls played.

"Three twos." After hesitating for a while, she drew three cards in her hand and threw them on the table.

"Damn, I don't." Hu Xi pursed his pink lips and looked at the orange-haired girl.

"Neither do I." Charlotte showed a helpless look.

"Then I still won this round." The corners of Hu Xian's mouth rose, and she put down the last card in her hand with a charming smile.

"I lost again. Huxi said bitterly.

"Continue." Charlotte refused to admit defeat.

She moves skillfully, packs the cards on the table, and starts to shuffle and deal cards flexibly with both hands.

Knock Knock???

At this moment, the door was knocked.

"Who?" Huxi asked back.

"Captain Huxi, the third elder of the Oasis is here." It was the voice of the highland guard.

"Let her come in." Huxi replied casually.

crunch...

The door was pushed open, and Bellian stepped into the room.

The fox fairy raised her eyes and asked lazily, "Your Excellency Bellian, what's the matter?"

Bellian said softly: "In half an hour, I will arrive at the Ice City, I am here to remind you to prepare.

"That's quite fast." Hu Xian heard the words and sat up.

Ice City is the third big city that Oasis will soon arrive at after leaving Xuanwu City.

The first two big cities received twenty-two people, and each city master brought ten subordinates.

In fact, there is no regulation on how many subordinates the city lord brings.

It's just that the size of Oasis City is limited, and in addition to personnel, there are many goods.

"Your Excellency Bellian, can you tell me what's going on in Bingcheng?" Huxian stood up, and the seven-colored cheongsam skirt on her body did not leave any folds.

"Of course." Bellian nodded.

She recalled for a while, and said slowly: "Bingcheng, the population is about 30,000, the city owner is called Binglake, who is a seventh-order mutant."

Bing Lake, a mutant with horns, is so powerful that he can lift several thousand kilograms of boulders with one hand.

So even if he is only a seventh-order master, it is enough to make many masters stronger than him retreat.

"A seventh-order powerhouse?" Foxxian nodded thoughtfully.

Huxi asked in a crisp voice, "Is there anything else that needs special attention?"

She has never been to Bingcheng, and her knowledge of Bingcheng is very limited. She wants to take the opportunity to learn more.

"Special attention..." Bellian's eyes flashed, as if recalling something.

"By the way, one thing is, after entering the ice city, don't just pick up items from strangers." Bellian said with a serious face.

"What is this taboo?" Hu Xian narrowed her rose-red eyes.

"It's not a taboo, but some people will take this to trick people."

Bellian shook his head and explained, "If you take something from a stranger, it is very likely that a transaction will be forcibly created."

"Forcibly trade with me?" Hu Xian raised his brows.

"

Fox Immortal chuckled: "Of course, if you are strong enough, you don't have to be taboo."

"Hehe, whoever dares to force a deal with me, I will slap him to death." Hu Xi reached out and clenched his fist and waved, looking eager to try.

"Go and put on your armor and prepare to enter the city." Huxian said charmingly.

"Okay." Huxi raised his hand and gave a military salute. He happily ran to the next room, took off the ghost armor and put it on.

Bellian is gone, and she also wants to enter the ice city to meet Bing Lake and explain the matter of the Holy Land Council.

□O

Oasis will only stay in Ice City for one day and leave before dark.

Half an hour passed quickly, and Bingcheng appeared in everyone's sight.

The ice city was built on a plain with flat ground on all sides. For safety, the wall of the ice city was ten meters high and three meters thick.

The oasis hovered in the air a few hundred meters away from the ice city.

A dozen black dots flew out of the camouflaged oasis and flew towards the ground.

tread???

With a pair of feet on the ground, Charlotte folded her wings and reached out to straighten her long orange hair that had been ruffled by the wind.

"Hey!!" Hu Xi got down from Charlotte and tidied up his appearance as well.

"Let's go." The fox fairy walked towards the ice city with a graceful gait.

She came down by the wind of Belle Lin.

The same is true of other highland guards and city defense troops, carrying wooden boxes in their hands, containing fruits, leaflets and other goods.

For this propaganda work, three highland guards and six city defense troops followed.

...for flowers...

Another highland guard and two city defense troops are responsible for staying in the oasis and guarding the remaining supplies.

Oasis sent the third and fourth elders to go with them to persuade Binglake.

Everyone walked towards the ice city, and soon approached the gate of the ice city, without being blocked, they successfully entered the ice city.

As soon as I walked into the ice city, the unpleasant smell hit my face.

"It smells so bad." The fox fairy flicked her tail, covering half of her face, leaving only her rose-red eyes.

With beautiful eyes flowing, the dirty streets are full of rubbish, and many filth can be seen.

"My God, this is the dirtiest big city I've ever seen." Huxi raised his hand to cover his mouth and nose.

She began to miss Xuanwu City. Compared with Xuanwu City, it is one day and one place.

"Forbearance." Huxian frowned and continued to move forward, carefully avoiding the garbage on the ground with every step.

"Go, let's send out the leaflet. Huxi turned his head and gestured to the following city defense troops.

"Yes." The city defense army responded respectfully.

They stopped, opened the wooden box and took out the printed leaflets, followed behind the fox fairy, and began to distribute leaflets to the city residents passing by. The flyers are paper, and in the eyes of Bingcheng citizens, they are considered treasures.

"Xuanwu City, have you heard of it?"

"No, the first time I heard it, I didn't quite believe what was written on it."

"What is it written? I can't read."

The citizens of Bingcheng were talking a lot, and they got together in twos and threes to discuss the truth and the false.

"Just here, clean up." Hu Xian stopped and pointed to the barely clean road.

"Mmmm, leave it to us here, Sister Huxian, let's go to see Bing Lake." Charlotte said crisply.

"Well, pay attention to safety, and contact the resonant bug if you have anything." Hu Xian said charmingly.

"Okay, don't worry." Charlotte nodded.

She and Huxi will stay and will be responsible for distributing leaflets and setting up stalls to promote the goodness of Xuanwu City.

The foxtail woman went to see the ice city master, informed the auction, and reminded the other party to bring more beast spar on the road.

The fox fairy took two city defense troops and followed Bellian and the oasis

U!

The elder continued to move forward.

It's just that they were stopped by a group of people before they went far.

"Beauty, here's water for you!" The man with the pointed mouth and monkey cheeks handed out a jar of water to the fox fairy.
