In front of the open space of the temple, the adults of the Dragon Tribe gathered here again, and Su Yan and the five patriarchs stood at the forefront.

Last year, in order to mine copper ore, Su Yan and several patriarchs divided most of the labor force of the Dragon Tribe into three teams, each team of 180 people, and rotated every ten days to mine copper ore, this year it is still three teams, but the number of people in each team has increased from 180 last year to 200 this year, of which each team has 80 male clansmen and 120 female clansmen.

A very helpless thing, the number of female labor force in the dragon tribe is always increasing faster than that of male labor, and the dragon tribe itself is fine, the proportion of adult men and women is not much different every year, but there are more women than men brought back from foreign wars.

I am afraid that it is because the tribes mainly use hunting as a means of obtaining food, especially in the cold winter, so that the male tribe has a higher chance of death than the female tribe.

On the third day after the team, Zhi took Team A to the mining area, walked on the road opened up, and walked to the copper mine in only half a morning.

Looking at Team A, who was walking far northwest, Su Yan pondered whether this road should be repaired and leveled, not only to speed up people's walking, but also to make a car to transport food and copper ore back and forth.

The plan was feasible, and Su Yan found Song, who was leading his people to burn bricks and build a tiled house.

"Song, I give you a task, take a hundred tribesmen to repair the road from the tribe to the copper mine, fill in all the pits, bulldoze all the soil bags, and finally lay a layer of small stones on it."

Listening to Su Yan's words, Song thought for a while, and after a few breaths, Song honestly touched his head with his hand and asked Su Yan: "Wang, where to find the pebble." ”

"Uh......"

Song's question stumped Su Yan, where to find the pebble? Pregnant!

"There are pebbles by the river, you go to the river to look for them, you can't find them by the river, you can look at the shallow water area in the river, you should be able to find the pebbles, and then you can directly use the small pebbles in a sack to carry them over to pave the way."

"Wang, I know, I will take my people to build roads." After Song finished speaking, he told Su Yan to retreat and gather a hundred clansmen to build roads.

After Song left with a hundred people, Su Yan handed over the task of burning bricks and building a house to Jian, and then Su Yan went around the smelting area again.

The construction of the new model of copper smelting furnace has begun after the spring festival, and five of them have been built in a row, all equipped with hydraulic bellows, and the three old models of copper smelting furnaces have all been demolished, and the dismantled adobe bricks have been used to build the new type of earth blast furnace, and several more brick kilns for burning charcoal have been built.

The new model of copper smelting furnace can smelt 600 catties of copper ore at a time, a furnace produces about 13 catties of blister copper, and five new models of copper smelting furnaces can consume 3,000 catties of copper ore a day, with a daily output of 65 catties of blister copper.

Only these five new models of copper smelting furnaces, if they can ensure the supply of copper ore and charcoal, the Dragon Tribe will be able to smelt more than 20,000 catties of blister copper in a year.

However, the real situation is that the three months of winter are too cold to open the furnace to smelt copper, and the summer is rainy, and it is impossible to open the furnace to smelt copper for nearly half of the time, and then subtract the rainy time in spring and autumn, there are only about 200 days in a year to open the furnace to smelt copper, and it is estimated that 13,000 catties of blister copper can be smelted.

A farm tool needs a maximum of one pound of blister copper, and 13,000 catties of blister copper can completely cast 13,000 farm tools, but the dragon tribe is only more than 2,000 people, and adults are just over a thousand people, so they don't need so many farm tools at all.

For the time being, the five new models of copper smelting furnaces are enough for the Dragon Tribe, and the Dragon Tribe's labor force is so much, so it is impossible to send too many laborers to the copper mine to mine copper ore at once, but fortunately, the blister copper smelted by the five new models of copper smelting furnaces is enough for the Dragon Tribe to consume.

Looking at the sweat on the upper bodies of the clansmen who were busy next to the copper furnace, and at the animal skins on their bodies that had faded to the bottom, Su Yan felt that he should put aside the idea of building wooden boats and wooden rafts for the time being, and it was better to make Mai first.

As we enter the first month of spring, the weather is getting warmer and warmer, and the tribesmen are wrapped in animal skins, and they will sweat profusely when they exercise vigorously or are busy in hot places such as copper smelting furnaces, brick kilns, and pottery kilns.

In winter, it is very uncomfortable to wear animal skins to keep warm, and now it is not suitable to change into clothes made of plant leaves, so the tribesmen can only endure it.

It just so happened that last year, the dragon tribe had already spun a fairly fine linen, and a year had passed, and those burlaps had to be made into sacks, and these fine linen cloths were more labor-intensive, and after they were temporarily put away and stored, it was estimated that the stocked linen cloth could also make hundreds of sets of linen.

Thinking of Mai, Su Yan remembered another thing he needed to do, the speed of spinning linen was still too slow, and the spinning wheel and loom should be manufactured.

The structure of the spinning wheel is simple and should be able to be manufactured, but the structure of the loom is very complex and cannot be manufactured in a short time.

Su Yan drew the matter of making spinning wheels and looms in his mind, and waited for the matter of Mai to be solved and then put together with the matter of making wooden rafts and wooden boats.

Back in the residence, Su Yan sent a few tribesmen to gather most of the female tribesmen who were unable to do heavy work because they were pregnant to the square in front of the temple, and sent a few tribesmen to fetch sackcloth, while Su Yan walked to the house where he lived.

If you want to quickly gather the clansmen, there is an easiest way, Su Yan casts a few gongs with a casting mold, and if you take the gong and strike it a few times, the clansmen will not be able to gather, yes, it is all the clansmen, and now Su Yan only wants the pregnant female clansmen to gather over, there is no need to use the gong.

Not long after, Su Yan took out another set of animal skin clothes from the house, a total of three, namely a top, pants, and shorts.

Su Yan walked towards the square in front of the temple with his clothes, and the pregnant women who already had slightly bulging bellies next to him came in groups of three or five, and they greeted Su Yan after seeing Su Yan: "Wang." ”

Su Yan nodded in reply.

Soon, the pregnant women gathered, and several men also brought two rolls of linen.

I didn't see Xiaohua Xiaoyue, the two of them should be teaching the children of the Dragon Tribe to learn dragon characters.

The pregnant women gathered in front of Su Yan, without any noise, they looked at Su Yan, did not dare to look at Su Yan's eyes, at most they put their eyes on Su Yan's upper body.

"Ahem, there's one thing I want everyone to do......"
