After making the mold, Wang Lang picked up some ore and threw it into the fire to calcinate, after the ore melted, the silvery-white liquid flowed on the ground, flashing with a unique metallic light, Wang Lang extinguished the fire and let the solution cool naturally.

Time passed in a hurry, until after breakfast had been eaten, the solution had solidified into lumps, and Wang Lang knocked the metal off the stone with a stone.

Stripped of the ash and rock debris above, the glittering silvery-white tin block caught everyone's eye.

People have never seen anything like it, and they all come up to touch this stone that is special in their eyes, and a cold, hard touch comes from their fingertips, and it is a very special experience.

Wang Lang looked at the stone and smirked, and the others also giggled with Wang Lang, although they didn't know why they laughed, but their intuition told them that it was a good thing.

Wang Lang put these tin pieces into the clay pot, set it on the fire and calcined, the melting point of the tin was very low, Wang Lang remembered that it was about 200 degrees Celsius, as the clay pot became hotter and hotter, the tin slowly melted.

Wang Lang held the branch and kept stirring it to make it dissolve more fully.

The other people who had nothing to do gathered around Wang Lang to watch this magic-like phenomenon, and everyone seemed to have a pious expression on their faces.

After the tin block was fully melted, Wang Lang asked people to bring the mold they had made before, and in order to prevent people from being burned, Wang Lang asked the dark cloud holding the mold to wrap his hands in animal skin.

Since the mold was not very flat, Wang Lang used mud to seal the connection between the two clay tablets.

"Be careful, don't move your hands! This thing is hot and dangerous! Wang Lang said to the dark clouds.

Wuyun nodded solemnly, took a deep breath and said, "Come on, I'm ready!" ”

Wang Lang nodded, holding the clay pot in both hands, and carefully poured the hot solution into it slowly along the entrance.

The silver-white solution was poured into the groove, and Wang Lang asked the dark clouds to carefully place this thing in the shade of the cave.

"Lang, what's next?" Dark Cloud asked.

"What to do! Just wait, I don't know if I can make it. Wang Lang shrugged his shoulders and said.

After a long and boring wait, the tin solution finally cooled and solidified, Wang Lang couldn't wait to open the mold, and a tridiamond-shaped arrow appeared in front of everyone.

However, due to the gap in the mold, there was a thin layer of tin on the edge of the arrow, and Wang Lang used a stone knife to cut off the extra tin piece on the edge of the arrow.

I found a smooth stone, sprinkled some water on it, put the arrow on it and polished it, and it didn't take long for an arrow with a sharp edge to be processed.

Wang Lang took an arrow shaft and put it on the arrow, but the sleeve part of the arrow was a little small, and Wang Lang had to rest the arrow shaft with a stone knife, and this time the arrow was firmly fixed on the arrow shaft.

This is the tribe's first metal weapon, this invention is absolutely epoch-making, Wang Lang decided that we must not forget this special day, and when the tribe has a written word, we must record this great thing in the history books.

"In a certain year, in a certain month, the king passed through a barren mountain, the evil demons of heaven and earth in order to stop the king, caused a catastrophe in heaven and earth, at the right time, the flood was monstrous, countless living beings died, but the king had the protection of the gods, all the evil demons could not hurt him in the slightest, the king had the guidance of the gods, found the mysterious ore outside the sky, made a divine arrow between heaven and earth, the day the arrow was completed, the evil demons retreated, the flood dissipated, thousands of living beings were saved by the king, and they were placed at the feet of the king."

Just as Wang Langmei was fantasizing about this mythical and legendary story, the arrow in his hand was taken away.

Wang Lang was stunned for a moment, and couldn't help but be a little annoyed, who dared to disturb his dreams so boldly, and when he saw Jianya gently stroking the arrow, and the corners of his mouth were about to grin to the root of his ears, Wang Lang couldn't help but smile.

"What are you smirking at, don't you try the power of this arrow."

Wang Lang's sudden voice startled Jian Yan, and after reacting, he thought of the excitement he had just cared about, patted his head, and hurriedly took off the bow on his back, and skillfully opened the bow and arrows.

"Lang, what should I shoot?" Solid Tooth asked.

Wang Lang touched his chin and thought about it and said, "Just shoot the big tree in front of you!" ”

"Good!" Tough Tooth howled excitedly.

Everyone came to the cave to see the power of the new arrowhead.

Jianya held his breath and aimed at the big tree five or six meters in front of him, and the fingers pulling the bowstring were released, and the arrow off the string flew out in the blink of an eye.

"Wow!"

After a muffled sound, the arrow was firmly nailed to the trunk of the tree, and the shaft of the arrow continued to tremble due to the great inertia.

Jianya hurriedly ran over to check the effect, only to see that the conical part of the tin arrow had completely submerged into the trunk of the tree, seeing that the arrow made of this melting stone was so sharp, Jianya trembled with excitement, what a warrior needed most was not a woman, nor food, but a well-made weapon.

As the saying goes, pink is given to a beautiful woman, and a sword is given to a hero, for a guy with developed limbs like Jianya, this kind of weapon is tailor-made for him.

"Hey! Jianya, what are you doing there, how is the effect of this arrow? The clouds yelled at the fangs.

Jianya came back to his senses and shouted excitedly: "What a sharp arrow, it pierced the trunk of the tree in one fell swoop." ”

Hearing the words of Jianya, people were very surprised, I didn't expect this beautiful stone to be so sharp, the stone arrowhead used before, not to mention the trouble of polishing, although it can also pierce the trunk, but the arrow in order to pursue sharpness, often use very thin stone chips to make, which leads to the arrow is easy to break, has no effect on hard things.

As long as this stone is melted, poured into a good mold, cooled, and then polished casually, it can be used, I don't know how many times easier than making stone arrowheads, and the men stared at the solidified tin in the clay pot, and their eyes almost lit up.

The arrow nailed to the tree was pulled out with great difficulty, and due to the soft texture of the metal tin, the arrow was slightly deformed due to such a violent impact.

Wang Lang looked at the twisted arrow, and felt a little regretful in his heart, although this metal is easy to process, there is no record of using tin as a weapon in history, which shows that this thing has great limitations.

Fortunately, the tin is easy to machine, and the dull arrowhead becomes extremely sharp after grinding in stone.
