The saber-toothed tigers were powerless against the main forces of the Riverlands, or rather, the elite hunters of humanity, unable to break through the spear-forming line, and behind this line were javelin axes rained down, and even more terrifyingly, a weapon they had never seen before was used in hunting and killing.

Bow and arrow.

The Greywood tribe's bow-making skills are very reliable, and Yang Li has trained five archers to arrange them to be behind the side of the spear formation to concentrate fire on the saber-toothed tigers.

Under the cross-type three-dimensional blow, the saber-toothed tigers were injured one after another, and Yang Li recognized that this group of tigers was the group that fought with him the day before yesterday.

Perhaps this kind of tiger ambush incident would be devastating if it happened to another tribe, but they were wrong because they chose the wrong opponent.

This group of humans is far more fierce than they remember, advancing and retreating in an orderly manner, and several of them even have the combat power of a single saber-toothed tiger, and as for the giant with three scars on his forehead, he can completely abuse several saber-toothed tigers.

When the tiger group was more than half dead and wounded, the giant tiger finally realized that the hunt had been a complete failure, but they had lost the opportunity to break through, and Hayabusa led a group of hunters, and at some point completed the siege.

In the spear and feather arrows, the tiger group was completely annihilated, and Yang Li ordered that the most outstanding hunters could get saber-toothed tiger skins.

At the end of the battle, the road construction team suffered heavy casualties, and instead of successfully escaping, the slaves who fled for their lives paid the price of seven lives; Two of the resisting clansmen were killed in the battle, and the remaining two were slightly wounded.

Yulia's face was covered in blood, and she took revenge by stabbing her spear into the tiger's heart during the siege, in fact, her sniper had recovered a bullet at this time, but she obviously wouldn't usually take it with her.

There were seven saber-toothed tigers, six of which were killed on the spot, and the last one was wounded by an arrow, and was chased out of twenty miles by Xue Pijiang with a bow and spear, and ran to death.

The largest tiger skin was given to Yulia, who used it to make a new mattress, and the other tiger bones and tiger claws could be used to polish and make bone needles and other tools, but Yang Li suggested that everyone keep the tiger bones as a souvenir.

Because the Riverlands will soon have new tools, and this kind of tools will lead the race into a new era.

The new personnel were assigned to the road construction team, and the Falcon Wing was really sent to be a road guard, and a few days ago because of his meritorious work in prospecting, this guy was awarded the title of commander of the Hewan Land Reconnaissance Battalion.

The little tiger quickly got mixed up with Zhen Mi, Yang Li was a little helpless, and glanced at Mao Mei tentatively, and found that the latter was also waiting for his decision.

Well...... Is this little guy really a relative?

But Yang Li and Yulia tried to touch the little tiger respectively, but they were both resisted.

"Then let them stay for a while?" I really don't know what to do, the little tiger is not aggressive before it is an adult, maybe when it is the season to find a girlfriend, it will leave on its own.

Yulia shrugged: "I'm okay with that. ”

As a result, there is another cat jumping up and down in the settlement, occasionally making a cameo appearance to catch mice, but only as a leisure time for fun.

Yang Li had already taken over the pottery industry, collected tons of azurite and tin ore, and the slaves who served as helpers were also called together to participate in the cause of bronze casting.

Smelting bronze is developed on the basis of smelting pure copper, which is a process from low to high, step by step, but the difficulty of smelting pure copper in azurite ore is low, and red copper can be obtained by burning it with a flame, so Yang Li skipped this step.

The most primitive bronze smelting method is to smelt copper ore and tin ore together, and the composition of the bronze obtained in this way is not easy to control, so it is also directly excluded by Yang Jiao.

Later, copper was smelted first, and then tin or lead ore was smelted together, which was an improvement, but it still did not solve the problem fundamentally.

If it weren't for the fact that the temperature of the kiln could not meet the requirements of ironmaking, the leader of Yang Da would not have considered the bronze tools, and directly entered the Iron Age, holding steel knives and hanging steel armor to hang and beat the stone natives, and it would be very pleasant to think about it.

However, the Great Leap Forward should not be carried out until the technology is reached.

Yang Li set up the notebook, and the evolved notebook automatically retrieved the previously stored information and presented it to Yang Li in a three-dimensional holographic mode.

According to the information screened by the mutation notebook, mature bronzes should be smelted in this way.

When smelting copper, malachite and charcoal are placed in the pottery, the charcoal is burned in the furnace, and the air is sent to it with a leather blower device to produce high-temperature melted ore, and the carbon monoxide produced at the same time absorbs the copper.

Well, it is also specifically marked that the ore needs to be replaced to avoid carbon monoxide poisoning.

Before melting, the first to make the fan, this fan, is the pottery, and the ordinary container is different, this kind of pottery has a certain strength, air permeability and heat resistance is also better, in order to make the surface of the utensils smooth better, the inner wall of the pottery fan has to be painted with a layer of paint.

This kind of pottery fan can generally only be used once.

This is why before climbing the bronze technology, we must point out the technology of pottery production, otherwise the bronze water flowing out of the furnace will be filled with what to fill and shape.

Several of Zhen's potters participated in the bronze casting operation, and they built a furnace, put charcoal, and burned the fire, and the metal copper and metal tin prepared in advance were thrown into the furnace, gradually changing from solid to liquid melting.

Two slaves manipulated their skins and puffed up the air next to the hot furnace, and the trumpet of labor sounded in the riverbend settlement.

Different copper-tin ratios produce different bronze textures, and Yang Jiao uses a ratio of 85% copper and 15% tin.

According to the famous pre-Qin ancient book "Examination of the Gongji", this is the proportion of bronze swords, according to 85% copper smelted bronze, taking into account both hardness and toughness, is the strongest weapon material in this era.

The fire illuminates the heavens and the earth, and the red stars are chaotic with purple smoke.

In the cheers of everyone, the bronze water flowed out, entered the pottery fan, cooled and formed, crushed pottery, and the first bronze ware in the river bay was born!

It's a yellowish spearhead.

Some online materials in later generations will describe the bronze as a brilliant color like gold, but in fact, it is only half right.

Bronze, depending on the copper content, the color transitions from golden yellow to grayish white - yes, the kind of bronze tripod used for sacrifice is golden yellow, but the bronze weapon with a slightly higher tin content does not have the special effect of brightening the eyes of a blind dog.

As for why the first bronze is the spearhead, because in terms of meritorious deeds, after Yang Li and Yulia came to the riverbend, the person with the greatest credit must be Falcon Wing. The most commonly used weapon of the falcon wing is the spear.

He is not the best one in martial arts, nor the most powerful, not the most killed, but with his help, Yang Li took on the heavy responsibility of the patriarch, mastered the surrounding terrain, and got first-hand information.

He also brought back cattle for cattle and found tin mines.

Those who have made brilliant achievements in war can be seen by everyone. However, the merits of the people who resettle the people's livelihood and build the settlements are not easy to be counted or noticed.

Yang Jiao wants to show with actions and rewards that we are not a nation that is reckless in military force, we attach importance to production and development, and we grasp both the sword and the plow, and we cannot leave anything behind.

The people of the entire riverbend were gathered together, curious to see what the big leader was doing.

Like the rest of the group, Hayabusa was drawn to the movement in the settlement, to see the cheers around the furnace, and to see the leader pick up the cooled pale yellow spearhead.

That expression was as if he was holding a rare treasure in his hand.

"Hayabusa!" Yang Li shouted.

Suddenly called by his name, Falcon Wing was a little inexplicable, he looked around, pointed to his nose, and scratched his head before he scratched his head and stepped forward after confirming that it was correct: "You called me?" ”

Yang Li took a piece of ash wood and put the spearhead on it, the spearhead was about three inches long, shaped like a willow leaf, the two sides were slightly sharp, the spear tip was extremely sharp, flashing pale yellow in the sun, and the murderous spirit was soaring.

The spear was handed to Hayabusa, who took it with both hands.

"Great Chief, this, this is for me?"

"You deserve it, the ore we collect now can produce at most one of these weapons, and there will be more in the future."

Falcon Wing's hands trembled slightly, nodded heavily, and after a little thought, he asked again: "Since the Great Leader gave me this thing, I want to test how powerful it is." ”

"Someone, get the leather armor!" Yang Jiao has this intention, his leather industry is preliminary, and he can't wait to experiment with the following.

The armor piece of ordinary pigskin tanning was fastened to an upright plank, and Hayabusa first had his men use flint spears to stab twice, and then he used the stone spear himself to stab and stab twice.

You must know that Hayabusa is the strongest spear in the settlement.

Yang Jiao wanted this effect, he motioned for the falcon wing to replace it with a bronze spear, and sneered: "Commander of the reconnaissance battalion, are you not full of breakfast?" ”

There was a burst of laughter from the crowd.

"How is it possible, can a piece of pigskin stump me?" Hayabusa was upset.

The old armor piece, which had been opened with two holes in the stone spear, was replaced, and a new piece of armor was hung up.

The falcon took a step forward and slashed his spear lightly, the sharp bronze tip like a hot knife cutting through butter, making an unhindered cut in the armor.

The scene was silent, everyone saw the performance of the stone spear just now, what kind of concept is this, one more block the spear assassination, it is one more life.

I thought that in the future, I would put on leather armor to fight, and a warrior in our river bay could top two other tribes, but as soon as the bronze spear appeared, it was over, and it was a dead ball, and it was two holes when it was stabbed, one on the leather armor and one on the chest, and it was not saved!

Yang Jiao really wanted to open everyone's eyes again, we finally used a big killer weapon like a mutant computer, how to do it for a while, and immediately waved his hand: "Add another layer!" ”

Two layers of pigskin armor are stacked.

The falcon wing is still pierced by a spear!

The entire tribe finally turned from exclamation to cheer, and they could already foresee the invincible scene of the warriors of the Riverbend in the future, with leather armor and bronze divine soldiers, it was also a one-sided slaughter without suspense against three times the number of Stone Age warriors!

It wasn't until Yang Jiao had people add three layers of leather armor that the bronze spear couldn't be pierced at once, but judging from the lethality it has shown so far, it is enough.

Hayabusa bowed to the spear given by the leader, then raised the spear with one hand and scurried in front of his people, raising his arms and shouting as he went.

Yulia approached and helped Yang Li wipe the sweat from her forehead, and gave her an encouraging kiss by the way.

Just today, Yang Li opened the prelude to the Heluo civilization entering the Bronze Age.
