"Witch, it's appeared, it's appeared! It's an ice cube!"
"There are really ice cubes!"
"Wu, you are so awesome!"
…
Everyone cheered when they saw the thin pieces of ice in the bamboo bowl.
Yang Cheng also had deep joy on his face. He had originally thought of just giving it a try, thinking that it would be fine anyway, so it didn't matter if he gave it a try.
I'm not really sure how to get the ice cubes out. After all, it's difficult to make ice with boiling water. Without a sealed environment and poor air pressure control, it's very difficult to succeed.
But unexpectedly, when the first well was opened, ice cubes appeared.
Immediately, the excited people shared the bowl of ice water and drank it.
In an instant, everyone's heart was so clear that they felt extremely happy.
Everyone was hooked, but they felt that the water in a bamboo bowl was still a little short of enough to drink.
Yang Cheng didn't waste any time and gave the remaining water to the giant panda and let it drink.
Then he touched the head of the giant panda that was so happy that it rolled on the ground, and then led the other people who couldn't wait to walk towards the next well.
Still doing the same thing.
First, the manhole cover was removed, then the windlass was turned, and the bamboo bucket containing the pottery was lifted up.
The pottery contained in this bamboo bucket is much larger than the previous one, almost twice the size.
Everyone watched Yang Cheng open it with anticipation. If there was ice in this pottery, the water in the pottery would be enough for the dozen or so people present to drink happily.
It is disappointing.
There were no ice cubes in the water poured out this time, only a little bit of ice slag.
However, everyone still had a good time drinking.
Although there are no ice cubes in this pottery, the water is cold, much colder than the usual well water, which is still good for relieving the heat.
Next, there are several pottery vessels.
Coincidentally, ice cubes were produced in water contained in small pottery vessels, while ice cubes were rarely produced in water contained in large pottery vessels.
Yang Cheng figured it out after thinking about it.
For the same material, large pottery requires more clay and has poor sealing properties, so the air pressure does not achieve the expected effect, resulting in no ice cubes being produced.
In this case, Yang Cheng doesn't have a particularly good solution.
Use copper to make a sealed container. Not to mention how to make it, just bake it at high temperature. Will the copper liquid melt with water and heavy metals appear, so Yang Cheng stayed away from it.
If there is no solution, then there is no solution.
Anyway, the ice cubes Yang Cheng is pursuing are used to cool down. Although the water has not completely turned into ice cubes, it is enough for cooling.
Just look at the happy faces of Yanhu and the others.
In the days that followed, Yang Cheng asked Lulu to build more containers to determine the best choice.
For this reason, Yang Cheng also requisitioned all the wells in all tribes.
The river is nearby and flows through the tribe. Everyone's domestic water and drinking water can be provided in the river.
Yang Cheng clearly divided the river from upstream to downstream. The upstream was used for drinking water, the middle stream was used for the canteen, and the downstream was used for washing clothes and treating wastewater.
Yang Cheng doesn't consider the issue of wastewater discharge. There are no environmental protection organizations in the world, and no one comes to ask him about the problem of wastewater discharge.
As the saying goes, you have to go to Long to see Shu.
Now that we have ice water, we just need to think about how to change the taste of the water.
Forget about drinks like Coke. The recipe was written on the Coke bottle. Yang Chengdu didn't remember it and couldn't even remember it.
Not to mention, making Coke is something that is simply impossible in the original world.
To be realistic, Yang Cheng felt that there were only two types of drinks that could be made in primitive society: one was tea and the other was juice.
In ancient China, there were various theories about the origin of tea.
Some think it started in ancient times, some think it started in the Zhou Dynasty, and there are also theories that it started in the Qin and Han Dynasties, the Three Kingdoms, the Northern and Southern Dynasties, and the Tang Dynasty. The main reason for the divergent opinions is that before the Tang Dynasty, there was no word for "tea", but only "tea". It was not until Lu Yu, the author of the Book of Tea, that the word "tea" was reduced by one stroke and written as "tea". Therefore, it is said that tea originated in the Tang Dynasty.
There are other theories that it originated from Shennong, Qin and Han Dynasties, etc.
But no matter what, in this world, there is only one origin - the tea found by the shaman of the Qingque tribe.
For this, Yang Cheng is ready.
As long as he finds tea, let Mu Qing record this great historical moment.
The role of tea is really important!
Tea has a strong health care effect!
It can reduce the risk of cardiovascular and cerebrovascular morbidity and death, lower cholesterol and blood pressure, and can also help reduce the risk of diabetes, among other effects in inhibiting the occurrence of diseases.
Not to mention, it can also improve immunity, have a slimming effect, help prevent and treat Alzheimer's disease... there are so many effects that I can't even count at once.
Especially for the Qingque tribe, which eats barbecue and boiled meat for many years, and eats meat three meals a day, its role is even more important.
In the past, everyone was fine when they were hungry and full, and they didn't eat much meat from ferocious beasts.
However, in the past six months, Yang Cheng has obviously discovered that the bodies of his tribe have gained a lot of weight, and an unhealthy white color has appeared on their faces.
Many people become drowsy and prefer to drink more water.
Such symptoms are very similar to vitamin deficiency, but this does not mean that the Qingque Tribe is lacking vitamins.
The Qingque tribe lives in the forest. There are many edible plants in the forest, such as wild onions, wild leeks, bitter herbs, sage, willow sprouts, mushrooms, etc. These are all that Yang Cheng spent a lot of effort to find for the tribe. , the bamboo shoots that Yang Cheng got for the tribesmen before are also one of them.
The reason why the tribesmen are like this is because they eat too much meat, milk and other hot, greasy, and difficult-to-digest foods from various ferocious beasts.
Tea is rich in vitamins, tannic acid, theophylline, etc. Tannic acid has antibacterial and sterilizing effects. Tea is rich in vitamins B1, B2 and vitamin C, which are extremely important to the Qingque tribe.
For tribesmen who often eat fat from beasts, the large amount of aromatic oil contained in tea can not only dissolve fat, but also lower cholesterol and strengthen the toughness of blood vessel walls, which can just make up for the shortcomings of the Qingque tribe's dietary structure.
In addition to the effects of reducing fat and refreshing people, tea can also neutralize various odors. Even because the people of the Qingque tribe often come into contact with the bodies of fettered beasts or vicious beasts, they will inevitably be infected with bacteria, and tea has the effect of sterilization and disinfection. , it became a good medicine for the people of the tribe.
To sum up, finding tea trees is something that cannot be ignored.
But where to find it?
Yang Cheng frowned deeply and became worried.
