Divine Desert Island Survival System

Pottery will indeed fail to fire. After all, these pottery clays are not 100% qualified, and there are some impurities in them.

The first piece of pottery that was taken out was cracked, and this large-looking pot was a defective product.

The second pot was perfect with no cracks.

The third, the fourth, the...

Of the 12 pieces of pottery, 8 pieces were successful. The success rate is not bad. Among them, the refractory pot that Zhao Yunxiang admires the most is the most perfect.

This refractory pot was made by an old man who took urine and mud. It is 1 meter high, half a meter in diameter, and 5 cm thick.

The old man's craftsmanship is good, this refractory clay pot can be used to smelt bronze ware.

The clay pot was completely cooled. Xiaoqiang filled the pot with some water and picked it up to drink.

"This is really convenient for drinking water!"

"Really, the boss is really amazing. After the mud is burned, it will become so hard, and the water will not boil at all."

Everyone in the tribe is passing and looking at the pottery. This kind of water storage container is simply a magic weapon!

"Thank you boss!"

"The boss is awesome!"

"I love you to death!"

Almost all the clansmen were grateful, and some even knelt down and began to worship.

For a moment, Zhao Yunxiang felt like he had become a god!

If more savages are recovered, then... Han Qianluo and the others will no longer be troublesome!

When the time comes~~~~hehehe~~!

No longer flirting, Zhao Yunxiang became serious. After all, time is running out now, Karazhan next door will call at some time, and the production of bronze ware is imminent.

"Now I will teach you how to smelt bronze ware." Zhao Yunxiang said seriously.

Everyone's ears perked up when they heard the bronze ware, and the legendary bronze ware was finally about to be made.

After Zhao Yunxiang was silent for three seconds, he discovered sadly that he didn't know how to make bronze wares at all, there was no proportion! ! !

Yes, all qualified bronzes have proportions. Red copper, tin alloy, and lead alloy are fused together in a certain proportion, and finally become bronze with strong hardness and toughness.

It's a pity that Zhao Yunxiang has no lead. The mixture of tin and red copper can only have hardness. This world is fair. God gives you hardness, which will greatly weaken your toughness.

For example, glass and diamonds, both of which are hard, but fragile!

"Boss... How do you make bronze wares?" Xiaoqiang asked Zhao Yunxiang when he saw his serious and embarrassing expression.

"Actually... I only know the simple method, and I have to experiment to find out the specifics." Zhao Yunxiang is a very real person, if he doesn't know, he doesn't know. How do I know the proportion of the bronze ware?

"Boss, you can take us for a try!" Xiaoqiang trusts Zhao Yunxiang very much, the boss is awesome, even if the boss has broken sleeves, I am willing! !

"Okay, then let's experiment!" Zhao Yunxiang held the red copper scepter and the spear blade sharpened by the patriarch, "The purity of red copper is very high, because the tin ore contains many impurities.

We first have to remove the impurities in the tin ore. "

Tin is a metal that often appears in our daily life. It is similar to the motherboard of a computer. Tin is used for soldering on it. The melting point of this metal is extremely low, only 230 degrees.

After violently removing the spear blade of the patriarch, Zhao Yunxiang put it into a refractory clay pot, and then added firewood to fire it. In just a few minutes, the temperature of the kiln reached more than 500 degrees. Obviously, the clay pot The tin has completely melted.

Those that are not melted are impurities, this is just some other ores and stones!

Pick up the residue, put the red copper scepter in, and continue firing. The melting point of red copper will be higher, about 700 degrees. Judging from the current situation, more firewood is needed to melt the red copper. copper.

"Let's wait here quietly now." Zhao Yunxiang thought for a while and asked, "Who among you can carve wood?"

"No..." Xiaoqiang thought for a while, "My uncle is best at making mud."

"Forget it, let me do it." Zhao Yunxiang looked at the kiln, and there were so few red copper and tin ores, it was impossible to fully arm the entire tribe.

If it is made into a spear blade, it can only be made at most a dozen, but if it is made into an arrowhead, it can be made into a hundred or so.

On balance, Zhao Yunxiang still plans to make arrows!

The ancients used the casting method to make bronze ware, which is to use clay, gypsum or the like to make a concave model, and then pour copper water into it. After cooling, the bronze ware is formed.

Zhao Yunxiang found a piece of wood, ground it with a rough stone and sharpened it with a stone spear blade, and finally made it into an arrowhead.

Finally, press the arrow in the mud to make a concave mold. There are at least a dozen molds.

Soon, the red copper in the kiln was completely melted, and the copper water and tin water were mixed together. I don't know if this ratio is correct. Zhao Yunxiang didn't have high requirements, and he only hoped that the bronze ware mixed with it would have hardness.

You must know that copper is rarely used as a weapon, mainly because it has no hardness.

The mixed copper water is scooped into the mold with a ceramic spoon. Zhao Yunxiang is very careful when doing this process. The copper water is scarce and he does not want to waste it.

After more than ten minutes, more than 200 arrows were made out of more than ten catties of copper water. These arrows basically reached the standard, but they still needed to be sharpened.

Time passed quickly. Today I spent most of the day making arrows and wooden bows. When the sun went down, I finally made a large number of arrows.

"This is the bow and arrow!" Zhao Yunxiang drew the bow and arrow, aiming at a tree in the distance, which is more than 40 meters away from here.

The bowstring of the wooden bow is made of slender bark. There are many trees growing in the forest, and the bark of some unknown trees is extremely tough. This is obtained after many tests.

Take aim, take a deep breath, and shoot your arrows fast!

"Whoosh!"

"Peck~!"

The arrow shot out quickly like a thunderbolt, and finally hit the trunk of a big tree accurately. It could be seen that Zhao Yunxiang pulled the bow very hard. When the arrow pierced into the trunk, the entire shaft of the arrow trembled.

"Hiss~!"

The savages had good eyesight and clearly saw the process of the arrow hitting the tree trunk, which shocked everyone.

Arrows appeared in the Neolithic Age 28,000 years ago. At that time, the arrows were made of flint. Zhao Yunxiang intends to let the tribal savages directly cross the Neolithic Age, directly from the bronze wares of the Spring and Autumn and Warring States Periods.

"Okay, you should practice archery now, and remember not to shoot at people." Zhao Yunxiang was very tired after working for a long time, and was planning to go back to the thatched hut for a nap.

People are tired, and they can sleep in any environment. After sleeping for an unknown amount of time, Zhao Yunxiang was awakened by a loud noise.

"People from the Karazhan tribe are attacking!!"
