Chapter 44 Large Excavator
This revenge and annexation operation went smoothly, but Luo Chong did not gain any other benefits except for the population.
Before Luo Chong was not the leader, the Han tribe was very poor, so poor that they were bleeding. Xie Ding's tribe was of course not very good either. In addition to the population, there were only some dried meat and fruits left. There was no stock of animal skins, no salt, and the pottery was exchanged from the Han tribe. It was really poor.
After returning to the Han tribe, the integration of the newcomers was also very smooth. There was the population that the Han tribe had traded from Xie Ding before as a basis. After all, they were all relatives.
Although the Han tribe did not have a pottery pot for each person as Luo Chong said, there were still many pottery bowls. After all, there was no need for so many pots. Several people could use one. The food reserves were indeed a lot. With the seizures this time, there was no problem for 200 people to eat for a whole winter. It was
just that the population carrying capacity of the cave had reached the upper limit. It could be said to be very crowded, but it was warmer to squeeze together. Seeing that winter was coming, no one said anything.
What surprised these people even more was that the Han tribe actually raised wild animals, especially giant monsters like Rourou and Huishan, which gave them a new understanding of the strength of the Han tribe. However, they are also very proud now that they have become a member of the Han tribe.
The women have been twisting ropes these days, and a team has been sent out to continue collecting nuts and fruits. It is estimated that such things will be consumed a lot in the future. After all, eating meat every day will get boring. Of course, only Luo Chong himself thinks so, and other tribesmen can't wait to eat meat every day.
The men continue to cut trees, leaving the trunks as building materials and the branches as firewood. Charcoal is no longer burned. Now the charcoal reserves are enough to refine the ore brought back by Luo Chong. Now the firewood is left for kiln burning.
In total, less than 1,000 kilograms of ore were brought back. It would be good if copper and tin could be refined together to produce 500 to 600 kilograms. Four small earthen furnaces were fired at the same time, and only about 30 to 40 kilograms could be produced every day. At this rate, it will take more than half a month to refine these ores. The refined copper and tin are all cast into gold and silver plates for storage.
Luo Chong has not been idle these days. He made the necessary woodworking tools one by one, and then cast 50 shovels, no, bronze shovels, but the shape is made according to the shovel. Among them, 40 are round-headed, which is convenient for digging soil, and there are 10 flat-headed, which is very convenient for mixing mud. A shovel head uses less than two kilograms of material, and the bronze output for two days is enough.
With the tools for digging soil, Luo Chong’s first phase of the water diversion artificial river project must begin. The work of transforming paddy fields is urgent. After all, time waits for no one, and it will be bad if the spring plowing next year is delayed.
Since it is a project, of course the project site needs to be mapped out first.
Using an extra-long hemp rope woven by women as a ruler, Luo Chong first measured the location of the city in the north of the cave, and then buried a log at the four corners of the city site as a mark to find the best river location.
The location of the river was also marked with a wooden stick, and then the brick kiln was built. Once the river digging project begins, a large amount of soil will be generated, so Luo Chong plans to dig the river and make bricks at the same time, and the brick kiln is located by the river.
The purpose of building the brick kiln by the river is explained, because it is a kiln built for firing blue bricks.
In modern society, most buildings use cement bricks and hollow bricks. Blue bricks have been listed as items that are banned from firing, and later even ordinary red bricks were banned, because firing blue and red bricks requires clay, especially the soil that has been covered by water for a long time in rice fields is the best. This has also led to some private small kilns destroying farmland in order to get soil for firing bricks, and later there was a ban on clay.
Although blue bricks and red bricks are made of the same material, the effects are very different. Modern red bricks have very poor anti-aging ability. The bricks of decades-old houses are all brittle, and you can pick them off with your hands.
This is because red bricks are light in weight, low in density, and have low resistance to oxidation and atmospheric erosion. Therefore, in order to protect the house and extend its service life, people with the conditions will apply a layer of cement on the brick wall as a protective layer, or even stick a layer of ceramic tiles on it to prevent the red bricks from being directly exposed to the air and exposed to wind and rain.
However, blue bricks are different. Most of the ancient buildings that have been preserved from ancient times to the present are built of blue bricks. Moreover, in the absence of a protective layer, blue bricks are directly exposed to the air and can still remain immortal for thousands of years. The anti-aging ability of blue bricks can be seen.
The biggest difference between blue bricks and red bricks lies not in the material, but in the difference in craftsmanship.
Clay contains a high amount of iron. After the brick embryo is made into a high-temperature firing and naturally cooled, the iron element in the brick embryo will turn into iron oxide, so the brick will turn red, and become a red brick.
Use the same clay to make bricks. After high-temperature firing, do not wait for it to cool down naturally. Instead, pour water into the kiln when the temperature in the kiln is the highest. The red-hot bricks will blend with water and fire in the kiln, producing a large amount of water vapor, which will squeeze out all the air.
At this time, the kiln is sealed to keep the kiln in a sealed oxygen-deficient environment with water and steam. The iron element in the brick will turn into ferrous oxide when the temperature drops, so the brick will become a blue brick.
In general, the process of blue and red bricks is that one is air-cooled and the other is water-cooled. They are just different in the final cooling link, and the rest are the same.
However, the density of blue bricks is much greater than that of red bricks. Under the same volume, blue bricks are much heavier than red bricks, and correspondingly more solid. Although they are not as solid as granite, they are not weaker than flint. Therefore, Luo Chong chose to make blue bricks. This is also the reason why the brick kiln was built by the river, because it is convenient to fill with water.
Lame fired a lot of red bricks some time ago, and these bricks were just right for building a kiln. The kiln was located by the river. It was cylindrical, gradually closing up, and made into an arched top with a smoke outlet on top. It was not very big, so it would be easy to seal.
The kiln was a semi-underground structure, with most of it underground and only a small part above the ground. The entire kiln took five days to build, using all the labor of the entire tribe, and most of the time was spent digging the pit.
It took some time to saw the logs into planks and make some brick molds, and the preparatory work was completed.
The giant plow that Luo Chong spent many days to build finally made its debut. It was a two-meter-wide wooden frame with four bronze giant plows installed underneath. As long as this thing was pulled up, it could plow two meters wide of land at a time, and the plowing depth reached 40 centimeters.
Of course, this thing was not used for plowing fields, but was specifically used to dig rivers. As for the power to start this thing, it was of course Rourou and Huishan. These two guys had been eating away at me for so long, so I had to find something for them to do.
Two giant plows were lined up side by side, with Rourou and Huishan in front, pulling the giant plow forward together, turning over the four-meter-wide river channel behind them. In less than an hour, the two of them had loosened the 700-meter-long river channel to a depth of 40 centimeters.
Luo Chong was overjoyed. At this rate, perhaps his city-building plan would not take three years. These two plowed the land once a day, and after 10 days, it was 4 meters deep. This is simply an excavator, and it only eats grass and does not burn oil.
