There are many ways to divide time, such as year, month, day, and four seasons. Among these many ways to divide time, Han Cheng feels that the best way to divide time is night and day.
It is used for working during the day and resting at night. The distribution is very reasonable.
Until people invented electricity, and the guy who persisted in inventing a durable electric light despite more than a thousand failures appeared, this reasonable division was increasingly undermined.
Driven by capital and other interests, the days are getting longer, the nights are getting shorter, and the time to sleep is getting shorter and shorter...
From this point of view, Han Cheng, who lived in a primitive society and had no access to electricity or electric lights, could indeed complain about things that were as bright as day.
Of course, it is unclear whether the sour ingredients in this complaint about not being able to eat grapes are contained in it.
As night fell again, Han Cheng abandoned copper smelting and many other matters with peace of mind. He lay half on the kang, hugging his picked-up daughter-in-law, feeling the increasingly powerful life in her belly, with a smile on his face.
Yingying.
Ever since he learned that Bai Xuemei was pregnant, this kind of thing had become a necessary homework for Han Cheng every night.
The happiness in this is not enough to describe to outsiders...
"Stop sitting and weaving, go pick some mulberry leaves for the silkworms and come back, and move around more."
The next day, Bai Xuemei was going to weave, but Han Cheng stopped her and asked her to pick mulberry leaves.
For people who are about to give birth, it is best not to sleep or sit for long periods of time, but to stand up more often, so that the time is conducive to giving birth and you will suffer less when giving birth.
Giving birth to a child is like going through hell for a woman, especially in primitive times and it is her first child.
Han Cheng didn't want to think that anything bad would happen to Bai Xuemei and his own children, so he paid great attention to these things.
Use your little knowledge about giving birth to children and try your best to reduce the risk factor.
Bai Xuemei obediently picked up a commonly used bamboo basket and went to pick mulberry leaves. Han Cheng thought for a while, then followed, and reached out to take the bamboo basket from Bai Xuemei's hand and let him hold it.
Of course, you have to take care of your wife and children by yourself. As for the matter of copper smelting, you can push it back a little. Anyway, it can't be done in a short time, so there is no need to rush it and compete for it in this day and night.
Looking at Bai Xuemei who was so happy that she was with him and wanted to jump up, Han Cheng felt that his decision was very correct.
At this time, the mulberries are almost ripe. The small, lumpy fruit is a little red on the side that is exposed to the sun, and is also white underneath.
The mulberries at this time are not very tasty yet. They taste sour and astringent with a bit of green flavor in your mouth. There is a big difference compared to the ripe, sour and sweet mulberries.
Han Cheng couldn't keep his mouth shut after eating two pills, but Bai Xuemei had no intention of shutting up and put one pill after another into his mouth. He was so happy to eat that Han Cheng couldn't help but look at it.
Live to produce saliva.
Not greedy, but sour.
Sure enough, a pregnant woman cannot judge it with common sense.
Bai Xuemei likes to eat sour food, which is not so unique.
The scary thing is those people whose tastes change because of pregnancy.
Some people like the smell of gasoline, and some like the smell of old houses...
For example, the daughter-in-law of a colleague of Han Cheng's later generations always liked to go to other people's pig pens during pregnancy, and then couldn't help but swallow her saliva while looking at the pigs in other people's pig pens.
At first, the colleague thought his wife was craving for pork, so he hurriedly bought it home and cooked it carefully. He found that his wife only ate two small pieces and stopped using her chopsticks.
After asking again and again, I found out that what I was craving for was not pork, but pig food...
After the bamboo basket was full of mulberry leaves, all the mulberries on one tree were gone. The white snow girl was still looking longingly at the other trees, as if she didn't want to leave.
What Han Cheng couldn't stand the most was her look, so he had to pick a lot more, find a big tree to wrap in leaves, and handed it to Bai Xuemei.
Han Cheng walked in front carrying a bamboo basket, and Bai Xuemei followed behind with mulberries to eat, so beautiful that her nose bubbled.
Han Cheng, who swallowed for a long time, felt that it would be difficult for the tribe to eat ripe mulberries this year.
After returning to the tribe and helping Bai Xuemei feed the silkworms and arranging the 'housework', Han Cheng found Hei Wa and worked with him on the new copper smelting furnace.
The copper smelting vat must be specially made, and a hole must be left at the bottom of the vat to allow the molten metal to flow out of the vat.
Of course, the lower the opening is, the better, because the lower the opening, the cleaner the copper juice inside will flow.
According to this standard, it is most suitable to open it on the bottom of the tank.
But of course this didn't work. After thinking about it, I made the opening on the tank wall as close to the bottom of the tank as possible.
As for the slag, after thinking about it, I came up with an idea, which is to take advantage of the fact that slag is not as heavy as molten copper.
Of course, don't scoop it out bit by bit with a spoon. This is too slow and dangerous, and it may not be able to get it clean.
The solution Han Cheng thought of was actually very simple, that is, to make a hole on the other side of the pottery jar. The position of the hole should be higher than this, so that the slag floating on the upper layer could be drained out.
All that's left is molten copper.
And with these two outlets, the large vat for refining liquid copper can be reused, instead of having to smash one at a time like yesterday.
As for the stove for burning the fire, it can be easily solved. Just replace the bricks with yellow mud and clay.
These two items are extremely resistant to burning and will not be burned like bricks.
After some discussion and sketching on the ground, the two finally decided on the shape of the special pottery jar.
Then the rest is Heiwa's performance alone.
After specializing in one thing for several years, Hei Wa's skills became more and more proficient, and he had already left Han Cheng, the man who brought Tao into the tribe, far behind.
Now watching Heiwa make pottery is simply a visual enjoyment.
The reconciled mud was as if it were alive in his hands. It was very obedient. Following his movements, it quickly became what he expected.
The whole process can be described as flowing like a flowing cloud and a commanding arm.
Before it got dark, a special clay vat with a height of more than 1.5 meters and a bottom diameter of more than 60 centimeters appeared in front of Han Cheng.
This pottery vat is also different from ordinary pottery vats. The difference is that the middle and upper part of the pottery vat is a little thinner than the two ends. It looks a bit like a vase for flower arrangement.
The reason why it has such a unique shape is that when designing, Han Cheng suddenly remembered the brick-built chimney of a steel factory that he had seen from a distance, with white smoke rising from time to time.
something.
Although I don’t know what its purpose is for the time being, since it was built like this in later generations, it obviously made sense, so Han Chenggong honestly used it.
