The discovery of tin is indeed gratifying, which means that as long as Wang Yang finds any other metal, he can make alloys and enter a new era.

Every time he thinks of this, Wang Yang is excited and high-spirited.

"It's going to rise, it's going to rise...... Ha Lu Ha! ”

When everyone saw that his whole body was trembling and laughing wildly at the sky, they knew that he must have found something good, so they also laughed with Ha Lu Ha Da Lu.

"Huh? What are you laughing at? Wang Yang looked at everyone puzzled, and when everyone saw that he didn't smile, he didn't smile anymore, he looked at each other, more puzzled than him.

"Forget it, let me see if using a metal spearhead will add some power."

He found a stick and carved a groove at the bottom, the bottom of which was large and the opening small, so that when the tin was poured in, it would not fall off.

In this way, it is not possible to make a formed wooden spear, and a template is also needed.

He found a small piece of wood, carved a groove to accommodate the front of the stick, and then carved a diamond-shaped groove at the top of the stick, which was the tip of the spear.

Then this small piece of tin was condensed again, and the tin turned into juice, which was poured into the groove in front of the wooden stick by Wang Yang, only to see the juice pouring into the groove of the wooden stick, and when it was full, it flowed back to the diamond-shaped groove.

After that, he took a large stone and pressed it on a wooden stick and waited quietly for the tin to cool down.

Early the next morning, when the tin had cooled, Wang Yang gently removed the stone, and the wooden stick was warped, and the tip of the spear made of tin shimmered in the sun.

Then Wang Yang polished it carefully and sharpened it into a spear-like tip, which was extremely sharp.

Everyone gathered around to take a look. Touching the tip of the gun, he nodded his head and applauded. It's much simpler than the stone spear tip they made, it just needs to be done. Just pour the juice and cool it, and the spear tip is larger, with a long spear edge like a knife.

Of course, this is the tip of the gun, not the spear.

Wang Yang was excited, this was much sharper than the tip of a spear made of wood and stone.

Although the wooden spear is simpler to make and requires less work, the tip is too blunt. Sharpened too sharply and not hard enough, animals with thick spines are very laborious.

The stone spear is very hard, but the loss is great, because the stone is so brittle that as soon as the tip of the spear is broken, the whole spear is useless.

The tip of the tin spear is much better, similar to the neutralizer of the two, harder than the wooden spear, and tougher than the stone. It also has a larger killing range than the tip of a stone spear, because the tip of a stone spear is extremely difficult to process, and it is very difficult to make a diamond shape with a spear tip.

Of course, due to the small opening of the stick. The groove is so large that the tip of the tin spear will never fall off and pierce the body of the prey. There is no need to worry about pulling it out because it is caught in the bone. Turned into a stick without a spear tip.

And the plasticity of tin is extremely strong, even if it is blunt. As long as you grind it gently, you can use it again.

Compared with the above two materials, there are really many benefits.

"It's a metallic substance, it's just different." Wang Yang laughed, and on a whim, he played with a spear.

"Look at my white crane shining wings! Hey! Ha! What's the matter, does it look like Zhao Yun? ”

Wang Yang posed, his face was full of pride, and everyone didn't react, not understanding what Wang Yang was talking about.

He didn't say anything, he just spoke with the facts, he found a sharp wooden spear and threw it at a spruce, "Boom! With a dull sound, the wooden spear pierced into the rough bark, the tip entered very shallowly, estimated to be only a few millimeters, the tip could not bear the weight of the wooden spear, and slowly bent down, and after a while, the tip of the spear broke, and the wooden spear fell to the ground obliquely.

Then he threw a gun made of tin.

"Boom!" With another sound, the sharp cone diamond-shaped tip instantly pierced at least a centimeter, standing firmly in the air, never falling.

"Woo~!" Everyone finally realized the power of the tin spear, let out a cry of surprise, stepped forward to pluck the tin hair, and watched left and right with love.

The bright and flickering blue front contains a different amount of strength. The chaser waved his hand and excitedly led the others to find a prey to try.

Wang Yang didn't pay attention to them, and found the ore, which was the size of a fist, with a pitted surface, a little gray on the outside, and brown on the inside, which looked similar to ordinary ore, inconspicuous, at least in Wang Yang's eyes.

"This is tin ore?" Wang Yang didn't know anything about it, but since this type of ore contained tin, he collected it.

He summoned his friends and asked them to follow an adult to find this ore, the friends were ignorant, and nodded stunned, they didn't dare not listen to Wang Yang's words, so they should go to play with their hearts.

The crowd soon spread around, looking for it.

Wang Yang was in the forest, and after looking for a whole day, he finally found a piece and brought it back to the stream, and the others also returned here, and it took a day of hard work to find five pieces, which was very inefficient.

But looking at the happy appearance of the exorcist and others coming back from hunting, it seems that the gun is still very easy to use, hip-hop playing, playing.

Wang Yang pulled the crowd over and decided not to migrate for the time being, stopping here to collect tin.

He suspected that there should be a place like tin in the vicinity, and if it could be found, it would naturally be mined in large quantities.

Thinking of the appearance of a large pile of metal being mined and piled up into a mountain, Wang Yang couldn't close his mouth with a smile.

He crossed his fingers there to calculate the power of tin.

"Well...... First improve the wooden spear, then make a knife out to see if it works, and then make an axe out, no, no, the axe may not be able to cut down the tree, it is too soft. Then make a few kettles, boil some boiling water, boil meat and soup, or make a few chests, I heard that tin in later generations was often used to store food. ”

Wang Yang did not forget that many cans in later generations were coated with a layer of pure tin, which had an excellent sealing effect and ensured that other metals would not change.

Perhaps the most impressive role of tin in later generations is tin foil.

Whether it's used for hair, hotel meals, or wrapping items, it's often seen.

However, one thing is clear, the production of tin foil is different from that made by Wang Yang, the tin extracted by Wang Yang is very coarse, and it contains messy ingredients, which should be harder than ordinary pure tin, which is a good thing.

At least for now, that's a good thing.

If you want to further produce and promote the development of the tribe, you have to find other metals, if nothing else, first find some copper, and refine brass and bronze, so that the weapon can be very sharp, it can be hard, and it can complete the leap of rebirth.

But this is a bit far, after all, the melting point of copper is too high, and it is impossible to refine copper like tin, and a good kiln is needed.

And the kiln, you need to find the clay.

He sighed: "It seems that there is still a long way to go, but it should not be far. ”

At noon the next day, the orthopedic surgeon found Wang Yang in a panic and made a new discovery! (To be continued......)
