The function of lime was recognized by everyone, and the last doubts about the casting of the fence were dispelled.

For brick-making and tree cutting, this kind of high-intensity manual labor also recognizes its necessity from the bottom of my heart.

In fact, before this, the life of the Tianlong tribe was hard, more just referring to the collection of food and the poor living environment, and the previous production activities such as fishing, hunting and gathering were basically sheep herding, lazy and inefficient.

The Chinese nation's hard-working quality should have been formed after settling down and attaching to the land.

It was Wang Tian who gave them a taste of hard work in advance. The common high-intensity labor further strengthens the emotional dependence between the tribesmen and the sense of identity and belonging to the group.

It was not until after the emergence of the state that human beings began purposeful city-building and spontaneous large-scale long-term population gathering.

Until then, all of humanity's energy had been spent on obtaining food and plundering territory and population.

This is in line with the hierarchy of needs theory proposed by the American psychologist Abraham Maslow in his book "Human Motivation Theory" in 1943. The book divides human needs into five levels from lowest to highest, namely: physiological needs, safety needs, social needs, respect needs, and self-actualization needs.

That is, Wang Tian, a traverser, does not play cards according to the laws of history.

He also seemed to be aware of this problem, and at the beginning of the crossing, the concern for safety made him mobilize almost all the forces of the tribe to build the city.

In his study of resource allocation, Marx used the story of Robinson, who survived on an island, as an example: "No matter how simple he was born, he always had to meet all kinds of needs, so he had to do all kinds of useful labor, such as making tools, making furniture, raising alpacas, fishing, hunting, and so on." Although his productive functions were different, he knew that they were only different forms of activity of the same Robinson, and therefore only different ways of human labor. The need itself compels him to allocate precisely the time he spends performing various functions. The weight of this or that function in all his activities depends on the difficulty he has to overcome in order to achieve the desired results. ”

And Wang Tian did his best to build the city, which in itself is unscientific.

This is not in line with the hierarchy of needs theory, but also contrary to the "boiling tea theory" in overall statistics.

After Wang Tian realized this problem, he decided to adjust the current production arrangement.

The increase in productivity depends on the improvement of the means of production, and making a net that can be used for fishing at this stage is not in conflict with building a city.

There is no food left before the first hunt, except for the food that has been dried and smoked.

He decided to harvest the two schools of fish that had not been caught before.

After making up their minds, everyone called it off, and it was almost noon, and it was time for lunch.

Leaving people to take care of the four pottery kilns, and adding a handful of firewood to the stove where the scales were fired, Wang Tian led the people to the fishing place.

Use a stone hoe to dig up the previously reserved water retention position, and the downstream is blocked by a fence, and the water falls out after the upstream is blocked. Due to the proximity to the estuary, the harvest was more than the previous two.

Wang Tian selected five fish that he estimated to be about one catty and two catties, and threaded them with rattan sticks and brought them back to the tribe by him.

The rest of the fish were put into baskets and baskets, and taken directly to the pond to be killed and cleaned.

The fire is the second to see the tribe come back. Start boiling water on the stove. Looking at the hot water in the soup pot that was about to boil, everyone clearly felt the secretion of saliva in their mouths, and consciously looked for wild vegetables nearby.

They found that the wild vegetables cooked in the soup pot were so smooth and delicious. It is a completely different texture from raw food.

Wang Tian collects two different weights of fish in order to confirm the standard unit of weight. For this unquantifiable unit, it is up to the human senses to make the standard, and each person will be quite different.

The solution to this problem is through democratic voting. Choose one or two of the most acceptable weights as the standard scale.

And now there is no salt in boiled food, and anyone who cooks cabbage in water is the same taste. Wang Tianke had little interest in getting involved.

The scales are ready to be made. The standard of the scale is waiting for everyone to decide, and now it is time to start making the scale.

Whether a pole scale is standard is closely related to the material and processing of the rod.

The material needs to be selected with small shrinkage, straight and not easy to produce deformation of wood, uniform density of walnut with fine material is the best product, and birch is more common.

At this stage, Wang Tian didn't have to choose, so he could only follow his feelings. He selected two pieces of wood with a thickness of three centimeters, which were about one meter long. The whole body is straight without knots and scars, and the weight is also relatively pressing.

Judging by the ease of breaking and peeling, it should have been dried for a long time.

The question of material selection arises again, how to cut?

Without tools, you can only use stupid methods.

Wang Tian took out the saw on the knife, sawed out a one-meter length on the selected weighing rod material, and then divided the whole rod into four sections and drew three circles as a mark.

First use the saw to gently see half a shallow mark at 1/4, then do the same at 2/4 and 3/4, but the depth of the sawing increases sequentially.

Finally, on the tail section, measure the length of six millimeters on a circular plane that is the same as the three half-circles sawed in front and mark it, and draw an elliptical pattern tangent to the top half of the scale rod with charcoal.

According to later generations, the shape of the scale rod resembles the shape of a fish. The head is large and the tail is small, the top of the scale rod is straight like the back of the fish, the side of the scale rod is oval like the belly of the fish, and the bottom gradually shrinks to call the tail of the rod.

Wang Tian's design is that the head of the scale bar is three centimeters in diameter, and then gradually shrinks from 1/4 to two centimeters at the tail.

Starting at 1/4 of the way, he gradually deepened the depth of the saws at the three phase limits of the semicircle. The change is greatest at the bottom.

Once you have made the mark, you can only use a knife to gradually cut off the excess wood.

In the bottom section of the weighing rod, the reason why only a depth of 6 mm was selected was that it was worried that the material would be scrapped due to excessive force.

It doesn't matter if the cutting is not in place, just come a few more times. And once it is scrapped, everything that was done before is in vain.

Wang Tian felt uncomfortable thinking about the work he had done that day. With his quick-tempered temperament, he is really not suitable for such meticulous work.

But the current situation is that there is no choice but to catch the ducks on the shelves. Wang Tian suddenly found that he had unconsciously persevered all the way. And it's not bad.

Man, sometimes the potential is forced out!

Life is sometimes like a general, the emphasis is on a balance, and the balance of talent is long-lasting.

And the process of moving the scale is also like the pace of moving forward on the road of life.

If you move too fast, you may lose your balance and hit the ground with a bang, and you will either be hit by the scale, or you will be injured by the sudden lifting of the weighing rod......
