The night was uneventful.

When the sky was bright, there was no longer the roar of wild beasts in the distance, only the noisy chirping of birds on the branches, full of morning vitality.

The primitive people who slept soundly also came together.

Feng Jiuli instructed Feng Duyan and the other three primitives to move the two large iron pots to the creek and instructed them to clean them with plant ash.

What is Grass Ash?

That is, the residues of herbaceous plants (weeds) and woody plants (dry firewood) after burning, which have a variety of functions such as fertilizer, medicine, disinfectant, etc., and can also remove oil stains from the pot.

Since drilling wood for fire.

The tribe has accumulated a lot of grass and wood ashes, so Feng Jiuli has people collect them and store them in the shade of the cave, which will be of great use when reclaiming wasteland in the future.

After washing the iron pot.

Feng Jiuli began to prepare to boil water, before because of the limited conditions, there was no way, so he could only drink pure natural stream water, but now there are conditions.

Feng Duyan felt very troublesome: "Chief, what is there to burn this water with firewood, isn't it good to drink it directly, waste dry firewood." And after boiling, the water will become hot and hot, making it impossible to drink at all. ”

"Yes, Ninth Sister, I'm already thirsty and want to drink water."

……

The other primitives nodded in agreement, and even a few little radish heads turned against each other, really disgusted by this extra behavior.

"No way!" Feng Jiu Li Yizheng refused verbally, and looked at everyone with a serious face: "There were no conditions before, so forget it, but now there are conditions, so everyone must drink boiled boiled water, and they are not allowed to drink raw water directly, well, that is, water that has not been boiled." ”

"Why?" The crowd was puzzled.

"Because raw water contains bacteria, viruses and parasites that are harmful to the human body. Drinking raw water can easily cause acute gastroenteritis, viral hepatitis, typhoid, dysentery and parasitic infections. ”

Seeing everyone's confused expressions of not understanding these terms, Feng Jiuli continued to explain in easy-to-understand words: "In short, there are many, many bacteria and insects in this raw water that we can't see with our eyes, just like the wound infection I told you before. ”

"The difference is that the wound is infected, the bacteria and bugs are in your wound, the wound pus is worsening, you can clearly know, well, there are more bacteria and bugs."

"And drinking raw water, you directly eat bacteria and bugs into your stomach, and breed more and more bacteria and bugs in your stomach, isn't it scary?"

"Yes!"

The primitives nodded creepyly.

"It's good to know it's scary, so listen to me! Believe in the ninth sister (Jiu'er), get eternal life. Feng Jiuli looked like a pyramid scheme brainwashed.

Afterwards.

She told them two more real-life examples of people dying because they drank raw water and had parasites in their brains, which scared everyone even more.

Feng Jiuli's daily tasks of popular science boiled water have also been completed, and she can get points rewards, and she also has points for building stoves, driving away tigers, and making bamboo bowls and chopsticks last night. However, the points for daily tasks are settled once every half a month, not counting yesterday and today, she still has to stay up for thirteen days.

It's Feng Shisheng.

The genius he understood a little, and said with curiosity - Alley, since the eyes can't see those bacteria and parasites, how can we see them?

"You need a microscope."

？？？

What's that?

Anyway, it was still early, Feng Jiuli explained what a microscope was, but unfortunately everyone was still dazed and confused when they heard it, and they had a feeling of being resigned to the Arabian Nights, so they had to shake their heads and leave, busy with their work. Only Feng Shisheng listened very seriously and meticulously.

After half ringing.

The water in the iron pot was also boiling, and Feng Jiuli asked Feng Duyan to scoop the boiling water into the bamboo tube with a big iron spoon, and then began to assign tasks again: "Feng Shisheng, Feng Anhuang, Feng Dongpo and Xiao Yi, Xiao Yi, Xiao San, Xiao Si stay, and use the hemp rope I brought back before to start making the door railing." ”

"The rest of the people, all go and cut down the trees! We must strive to make the door railing to keep the beast out of these two days, so that we can sleep peacefully at night! ”

Otherwise, you will have to work hard all night and not talk about it, and you will not be able to sleep steadily.

Seriously.

After last night, unless the people who kept the night vigil were Feng Shisheng and Feng Duyan, the others Feng Jiuli didn't believe it, so they had to put down other work at hand and make the door railing with all their might! Fortunately, yesterday she hunted a sika deer weighing seventy or eighty pounds and came back, which was enough for them to eat, otherwise they would have to waste manpower looking for food.

"Yes!"

The crowd also understood that the doorway was important.

"Feng Duyan, you are responsible for leading the team, leave the scissors, hoes and hemp rope, and you take the rest of the artifacts with you."

"Good!"

"In that case, let's get to work!" After Feng Jiuli gave an order, everyone threw themselves into their busy work.

Looking at the remaining Feng Shisheng and them, Feng Jiuli detailed the task again - the children were responsible for digging pits about fifteen centimeters wide and fifty centimeters deep on the left and right sides of the cave; Together with Feng Shisheng, she carried the wood stacked outside the cave to the entrance of the cave and fixed it with hemp rope.

Feng Duyan's side is also a division of labor, some people are responsible for cutting trees, some people are responsible for moving, and some people are responsible for trimming...... It's a lot of fun.

In order to have the strength to work, at about ten o'clock in the morning, everyone ate a meal; At three o'clock in the afternoon, I ate again, twice a day.

Fortunately.

After a whole day of unity and busyness, everyone's work results are still very impressive, Feng Jiuli's doorrail has been completed more than half, and Feng Duyan's tree cutting task is almost completed.

At night, it was Feng Jiuli and the three of them who were responsible for keeping vigil and taking turns to rest.

Everyone is estimated to be really tired, although there is no weed mat and the ground is hard, but they still sleep very soundly, and snoring is everywhere.

Day after tomorrow.

It took another morning, and the production of the cave door bar was finally completed.

At this time, Feng Jiuli stood in front of the cave, looking at his own

——

The night was uneventful.

When the sky was bright, there was no longer the roar of wild beasts in the distance, only the noisy chirping of birds on the branches, full of morning vitality.

The primitive people who slept soundly also came together.
