The copper branch has 600 people, 200 soldiers guarding the town, 100 refined civilians, 100 transportation slaves, and 200 mining slaves, and can mine 600 catties of ore every day, refining more than 100 catties of pure copper.

Copper mining and copper smelting is like building salt mining, rain, snow, wind and frost, heat and cold, may affect mining and refining, even so, there is an annual output of nearly 10,000 catties, and the tin needed to refine bronze is also a lot of money.

The tribe adds tin coins, and there are only 10,000 catties, which is definitely not enough for the need for bronze, and next to the headquarters of the wood tribe, there is a lead mine, but the lead mine is very toxic, and it is a little risky to mine it.

However, when Mu Wu made a second inspection, he inspected those green areas and found several ore veins, two tin ore and three lead ore, which were less than the output of the copper division, but they were enough to be used for a long time.

And the distance is not far, a tin mine is near the salt mine, only a few miles apart, handed over to the fire branch for mining, and a lead mine is around the copper mine, a distance of more than ten miles, and the copper branch sends people to mine.

In the past, the tribe only had tin, no lead, and the earliest bronzes were all copper tin, and with the available lead, the wood witch also improved the recipe, and the bronze that fused with lead was harder and sharper, and the weight could also be increased.

Ordinary tribesmen have the strength of 100 catties, and after becoming a warrior, they can lift 300 catties of weight, and the flesh and blood warriors can move 500 catties, and the peak of the flesh and blood warriors have the strength of nearly 1,000 catties.

And the clansmen of the wood tribe, who have eaten the spirit plant for a long time, have better strength than normal people, and the weapons of a few catties and more than ten catties are naturally not satisfied.

The bronze halberd of the heaviest old leader is only fifty catties of specifications, and now that the tribe has financial resources, of course, it is necessary to make the clansmen satisfied, and the new bronze of the three alloys is also time to come out.

At the same time, Muwu minted copper, silver, and gold coins, and recycled tin coins from the tribe, one tin coin was equal to one copper coin, one hundred copper coins was equal to one silver coin, and one hundred silver coins was equal to one gold coin, and the monetary system was thoroughly formulated.

And introduced the corresponding law, involving trade and currency, emphasizing that it is not allowed to steal other people's currency, not to mint currency without permission, not to destroy currency at will, and in serious cases, even demeaning status.

Some of them are far away~ To get back to the point, in the tense and busy days, the wood tribe encountered a threat again, and the threat came from the forest department, but not the forest department itself, but the mountain tribe under the command of the forest department.

There are eleven subordinate tribes like the Fire Tribe and the Wood Tribe, and the weakest ones are also those with a population of more than 1,000, and there are warriors and witches with abilities, the Wood Tribe is the weaker kind, and the Mountain Tribe is the strongest one.

The population of the mountain tribe is 4,000, the warriors are close to 2,000, and there are five special warriors, and Wu is also a flesh and blood warrior, owning thousands of slaves, and the influence range is nearly 1,000 miles, which is the strongest under the command of the Lin Hou Department.

Every year, a large number of warriors, clansmen, and slaves were recruited, which in turn affected the subordinate races, and they were on the same page with each other, often setting off wars.

Next to the wood tribe, there is the mountain tribe, the mountain tribe is on the edge of the jungle, there is a big salt mine on the edge, and there are also tribes on the side of the salt mine.

The Great Salt Mine was constantly being transferred between the two tribes, and in a recent battle, the Mountain Tribe was ambushed and suffered heavy losses, losing not only the salt mines, but also a Warrior with Abilities, unable to compete with each other anymore.

The population of the tribe is too large, and the daily consumption of salt is also a huge problem, and there must be no salt, and the transaction costs too many materials, so the mountain tribe put the idea on the wood tribe.

If the Fire Tribe is still there, the Mountain Tribe may consider it, after all, the division is unknown, and the Fire Tribe has two ability warriors, and the strength is not weak and underestimated, but I heard that it was replaced by the Wood Tribe, and there is only one ability warrior.

In the sixty-third year of the Wood Tribe, the Mountain Tribe gathered a thousand warriors, led by three warriors, declared war in the name of revenge against the Fire Tribe, and launched an attack on the Wood Tribe.

When the Mu tribe received the news, they immediately mobilized 600 teams, 100 medical rescue teams, and 100 supply transport teams.

Compared with other tribes, the people of the mountain tribes are significantly different, their bodies are stronger, their average height is a foot, their skin and flesh are as hard as rocks, and their strength is huge, and they can defeat one against two, but the speed is relatively slow.

The cavalry, which has always been invincible, lost in the war for the first time, and could not break through the ranks of the mountain tribes, unable to form an effective cut, and the cattle cavalry was in a slightly better situation, after all, the strength was strong, but the horse cavalry became chicken ribs.

Although the warriors of the Wood Tribe are well-trained, it is still difficult to resist the attacks of the Mountain Tribe, and the high-level strength is not as good as the other party, the Mountain Tribe has three ability warriors, and the Wood Tribe has only two, and Yu has just awakened.

One can control the soil, make the rocks bulge and dent, make the ground crack and close, one can petrify, make the body invulnerable, and make others petrified, and the warriors of the mountain tribes are like that.

The last person can escape freely, when lurking underground, no one can detect it, very good at sneak attacks, originally lurking underground, Yu and Yu did not find out, was successfully attacked by this person, and took the lead in severely injuring Yu.

The war between the two tribes lasted for five years, and finally ended in the defeat of the Mu tribe, the 600 warbands were reduced to less than 400 people, the cavalry lost more than half, and the 20 peak flesh and blood warriors lost more than half.

Mu Wu and Mountain Wu negotiated for a long time, agreed to the mountain tribe's request, paid tribute to the mountain tribe every ten years, and handed over 10,000 catties of salt and 100 pottery.

Originally, the Mountain Witch wanted more, such as the sharp blackstone weapon, such as the kind of bow and arrow that shot far away, such as the freely controlled war horse and war ox, but was sternly rejected by the Wood Witch, and he refused to compromise at all.

At the right time, Yu Ye successfully awakened, and after consolidating his strength, he immediately rushed to the battlefield, and Yu Awakening's ability was not wood, but wind, he could master the air current, and he could set off a strong storm and destroy things in a large area.

Or extract the air, suffocate people, and condense the cyclone under your feet, so as to achieve the true meaning of flight, the moment it falls from the sky, it really shocked countless people on the battlefield and made the two tribes stunned.

The mountain witch felt that the threat of Yu was far greater than that of Yu and Zhang, because he could run, and if he flew, the warriors of the tribe could not do anything about him at all, and they could fight and flee if they wanted, which was definitely the most troublesome trouble.

Originally, the strength shown by the Wood tribe exceeded their expectations, and the mountain tribe also suffered casualties, and if they really wanted to force a war with the wood tribe, even if they could win in the end, the mountain tribe would definitely suffer heavy losses.

To be able to get a fixed rock salt offering, has reached the expectations of the mountain tribe, ten thousand catties, it is definitely not enough, but there is no need to dig it yourself, and there is pottery, you can take it outside to exchange salt.

Seeing that the Mu tribe was resolute, there was no need to think about other things, and it was worth the trip to get salt and pottery, and the mountain witch agreed to the matter after a little thought, and asked the wood witch to prepare immediately and hand over the first year's offering.

10,000 catties of salt and 100 pottery were quickly delivered, and the mountain witches who were enshrined returned triumphantly with the warriors, leaving only the gloomy wooden tribe, not only lost a large number of resources, but also lost more than 200 warriors.

The following year, the angry Mu Wu, taking advantage of the time to pay tribute, informed Lin Hou of the matter, and denounced the atrocities of the mountain tribe of "their own people" beating "their own people", hoping that Lin Hou would give the Mu tribe the decision and let the mountain tribe give an explanation.

However, Lin Hou's reply to Mu Wu was only: The threat of external falls, Lin Hou will settle it for you, as for the contradictions between internal falls, you can solve them yourself, Lin Hou will not interfere, this is the rule!

Yes, the mountain tribe is the henchman of the forest Hou department, and the wood tribe is just a "usurper", how can people help you as an outsider and teach your siblings a lesson? Does the wood tribe have this qualification?

Mu Wu returned to the tribe in discouragement, and did not tell the clansmen about it, only to annoy them, and soon arrived at the seventy years of the Mu tribe's great sacrifice, today's sacrifice is a little deserted, mainly because he is absent-minded.

There are only 200 slaves and 100 civilians in the salt mine, and the annual production is about 20,000 catties, and the consumption of the tribes is more than 10,000 catties, plus the trade of the surrounding tribes, the rest can have more than 2,000 catties, which is barely enough for the two tribes to worship.

The population of the tribe is growing, and the need for salt is also increasing, and with the current production, it must not be able to keep up, and the two stone roads connecting the copper branch have been paved, and the fire branch has drawn two hundred slaves to the salt mines.

Since the beginning of the 70th year, Muwu has accelerated the process of exploration, basically cleaned up the remaining green areas, obtained a lot of medicinal materials, and discovered a lot of ore veins, tin ore, lead ore, aluminum ore, zinc ore......

Tin ore and lead ore can be used to refine bronze, and bauxite zinc ore can be used to make utensils, some of which are near the three branches and can be used at any time, and some are far away, and some of them are mined in the fire branch for backup.

There were even two silver mines and one gold mine, and even three new copper mines, and most importantly, he found five mines, the nearest open-pit mine, right next to the fire branch, only fifty miles away.

Copper smelting, pottery making, cooking, heating...... The tribe's demand for fuel grew, and when a lot of people were invested in cutting down trees and burning charcoal, coal became important, more resistant to burning, and hotter.

After paving the stone road, the clansmen of the fire branch began to dig coal mines, and the mining of underground coal mines may be a little troublesome, and they must pay attention to poisonous gas and collapse, but the open-pit coal mine will not have so much trouble.

There were not enough slaves in the fire branch, so they transferred a hundred from the copper branch, a total of two hundred slaves, one hundred civilians, and one hundred warriors, and threw them into coal mining.

The output of the copper branch will definitely be affected, and the output of bronzes will decline, but it will be enough for the tribe to use, and the bronze will not be used in the tribe, and it will not be taken out and traded with anyone.

As coal mining entered the right road, a steady stream of coal was transported to various ministries, completely replacing charcoal, liberating a large number of manpower, and the higher calorific value of coal, but also accelerated the process of copper smelting and salt boiling.

After the coal mine, Tao Zheng also made a breakthrough, the clay liquefied at high temperatures, forming a colorful glaze, which is stronger, lighter, and more beautiful, and is deeply loved by the tribesmen.

In terms of the headquarters, they began to try to expand outward, and the main direction of expansion was the grassland, the main reason was that there was not enough land in the tribe, and the land for living was more than enough, and the key was that there was no land for cultivation.

The fertile land on the original wasteland has been reclaimed into 1,000 acres of fertile land, which is an important source of food for the tribe, but the population of the tribe has expanded rapidly, and the output of the land has gradually failed to keep up with the consumption of the tribesmen.

500 acres of wheat, the mu production capacity of 1,000 catties, can be cultivated three times a year, the annual harvest of 1.5 million catties, plus potatoes, sweet potatoes, soybeans and other grains, can have more than 2 million catties of harvest, is really expensive.

However, the population of the tribe is also large, the food of the tribe is very large, adults are two catties a day, soldiers are five catties a day, the annual consumption of the tribe is nearly 10,000 catties, in recent years, they are relying on the surplus grain in the warehouse to survive.

It is still the spiritual plant energy in the headquarters, and if it is replaced by other wild plants, the number may increase several times, and if the tribe wants to continue to develop, the problem of food must be solved, and the reclamation of farmland is imperative.

After years of clearing and killing, the fierce beasts on the grassland have dropped significantly, especially in the area close to the tribe, the security has increased a lot, and the tribe is ready to build a city wall for ten miles on this side of the grassland.

It is ten miles long, ten miles wide, and there is a high wall of three zhang high and one zhang wide on the side, and the ten miles in the middle is the outer city of the tribe, half of which is used to raise and train cattle and horses, and half is used to reclaim farmland.
