"Lianhu, do you know where the mines near Peach Blossom Town are?" asked Wang Xijia as he walked out of the blacksmith shop. Peng Lianhu is also a local, so he may be able to know some information.

"Who doesn't know this? Isn't it just 50 miles away? The iron ore in our village also came from that mountain, don't you know?" Peng Lianhu asked Wang Xika in surprise.

"I don't know, I didn't care about this before. Wang Xijia thought to himself that this information turned out to be known to the locals, and it seemed that his 50 taels of silver had been spent in vain. But he doesn't care - the daughter is gone, and she will come back.

Wang Xijia knew that the gold, silver, copper, iron, various minerals and salt of the Qing Dynasty were all under official control, but no one took care of these resources before Emperor Wu of the Han Dynasty. In this era, it was basically whoever found it was whom, and he thought that the mines near Peach Blossom Town must have been dug up by those who opened private mines, but when he came, he found that there were basically no mines - just some rut marks on the ground. It belongs to an open-pit mine, and ore is everywhere. Because the current era is so old, no one has ever thought of monopolizing minerals.

In the next few days, Wang Xika taught Zach how to beneficiate, how to strip off the floating soil and surrounding rock on the surface of the ore, how to build a simple blast furnace with clay, and how to smelt iron.

Zach learned with relish, Wang Xijia listened to whatever he said, and asked some questions from time to time, like a college student majoring in mineralogy. In fact, Wang Xijia has only seen the knowledge of minerals in textbooks before, and it is inevitable that he will be in a hurry when he practices it for the first time, but fortunately, these primitive processes are not difficult to master, and Wang Xijia has also seen how Liu Blacksmith strikes iron. It didn't take long for everyone to be able to make weapons such as iron axes and hammers that were more skilled than Liu Blacksmith.

Out of his love for the martial arts novel "The Legend of the Condor Heroes", Wang Xijia made a cast iron heavy sword of more than 80 catties out of pig iron and gave it to Zack. The strong Zach loved this gift, danced vigorously, and refused to stop, which was the joy of a primitive man's direct transition from the Stone Age to the Iron Age.

"With this sword, no one can beat me, not even the poor!" Zach said happily.

"Yes, you're basically invincible. Wang Xika is also sincerely happy for Zack.

"Who is more powerful in this sword or atomic bomb?" Zach asked a very innocent question, still vague about the power of the various weapons.

Wang Xika was drinking water, and when he heard this question, he sprayed directly: "That should be the atomic bomb." Not a notch"

"I want to learn how to build an atomic bomb, can you teach me?" Zach had a lofty goal.

"Brother, I want to teach you, but I don't know much about it myself, so I can only tell you some basic principles, and you can figure it out for yourself. The most basic element that makes up matter is the atom, which has a nucleus. The division of one nucleus into two is called nuclear fission, and the fusion of two nuclei into one is called nuclear fusion. The atomic bomb is made of the nuclear nucleus of uranium-235 for fission reaction, and if the nucleus of heavy hydrogen elements such as deuterium and tritium is used for fusion reaction, a fusion nuclear bomb can be created, which is more powerful than the atomic bomb. As for how to turn one atomic nucleus into two, and two atomic nuclei into one, I don't know, you have to rely on yourself to comprehend" Wang Xika taught Zach what little knowledge he had about nuclear physics, just like a martial arts master passed on a set of internal skills to his apprentices that no one knew how to practice.

Zack thought about Wang Xijia's words, and muttered "atoms, nuclei, nuclear fusion, nuclear fission...... as if he was chanting, and waved the sword in his hand vigorously, as if he wanted to split the atomic nucleus in the air.

A strange feeling suddenly surged in Wang Xijia's heart: maybe Zach could really build an atomic bomb. Although it is somewhat inconsistent with objective laws to let a primitive man who has just transitioned from the Stone Age to the Iron Age make nuclear weapons, for safety reasons, Wang Xijia still advised: "The world with atomic bombs is a terrifying world, and I have heard that human beings were finally exterminated because of nuclear war." If possible, try not to build an atomic bomb, in this era, it is enough to be able to master iron tools. ”

Zach looked up, his eyes were particularly bright: "I don't build atomic bombs, but I don't think it's enough to use iron alone." What if this mine is taken over by someone else?"

Wang Xijia said: "Probably not, this is an ownerless mine. Even if someone else is occupied, you can go and find a new mine. There are many mines in this world, including iron ore, copper ore, gold ore, and silver ore. You just have to remember that in this era, as long as you master iron ore and salt mines, you can master the whole world. ”

Zach said gratefully, "Our people used to come to Peach Blossom Town to buy iron and salt, but we never thought of looking for a mine by ourselves, so I really want to thank you." ”

Wang Xika said: "Actually, I don't know much about the terrain survey, in our time, there were many ways to survey minerals. You can use drilling, or even radar remote sensing, and you can see what mines are in the ground at a glance. But now you can only find it yourself. ”

Zack said: "Actually, I learned some ways to find ore from you, such as if you want to find iron ore, you chase the blacksmith shop, and if you want to find a salt mine, just follow the salt seller." ”

Zack is quite good at drawing inferences, Wang Xika is more and more fond of this smart savage, if Zack lives in modern times, he will definitely be admitted to a prestigious university. Wang Xijia said: "In fact, the most valuable mine is not iron ore, but gold ore, diamond ore, jade ore and the like, oil, coal mine is also very valuable. ”

Zack didn't quite understand the nouns Wang Xijia said, and Wang Xika popularized some scientific knowledge that he knew to this primitive man, such as oil, the use of coal mines, and so on. He suddenly remembered the mantra of "Pipes, Counting Pieces", which was about the skills of the Yellow Emperor and his minister Bo Gao on finding mineral veins in this era, so he told Zack: Those who have dansha on the top have gold below. He who has a magnet on top has copper and gold below. There is a mausoleum stone on the top, and lead, tin, and red copper under it. There is ochre on top, and iron below.

Zach silently jotted it down and said, "Is this your modern technology?"

Wang Xijia said: "No, this mantra is a prospecting law invented by your enemy Xuanyuan tribe, if you want to defeat the enemy, you must understand the enemy." ”

Zach was sad: "I didn't expect the craftsmen's skills to be so far ahead of us, and it is really difficult for us to defeat them." ”

Wang Xijia comforted Zack, the technical gap between their Maoren tribe and the craftsman tribe is not so big, as long as they learn the other party's smelting technology and have weapons, they still have to fight.

"But we don't want to learn. You also see the attitude of the ball and the poor. We, a race that does not want to progress, are doomed to failure. Zach didn't know what was going on, and his mood was getting lower and lower.

Wang Xika had no choice but to comfort Zack, there are still people like you who are willing to learn, and they will definitely not be extinct.

According to the physical quality of the Maoists, as long as the craftsmen are close, they will be sent. The key lies in the ranged weapon, the bow and arrow. Wang Xika asked Zack, why do Mao people never use bows and arrows?

Zach scratched his head and said, "We think it's a coward's stuff to shoot arrows far behind." ”

"And what are you going to do when you hit the enemy from afar?"

"We mainly throw spears. ”

"That's not good, in terms of combat efficiency, throwing a spear is much less efficient than a bow and arrow. You must learn to use a bow and arrow!"

Wang Xika took Zack everywhere to buy bows and arrows, but the primitive wooden bows and arrows in Peach Blossom Town were too fragile for Zack, like toys, and they broke when he pulled them. Wang Xijia had no choice but to decide to do it himself, in modern society, he had never made these cold weapons, but fortunately, the basic principles were still known. After some difficult experiments, Wang Xika successfully reproduced the famous anti-horn bow of the Manchurians and the English longbow. It's a pity that these bows are too fragile for Zack, and they will break when they are pulled - Zack's physical fitness can only be regarded as average among hairy people, but it is still much stronger than ordinary people.

Xika made certain improvements to these bows and arrows according to Zack's body type, using repeatedly built wrought iron tires and horns to make a pair of strong bows more than two meters long, and twisted 10 strands of velociraptor tendons into a powerful bowstring - this time it is constantly pulling, to be honest, Wang Xika can't pull this bow at all. Zack used this bow to shoot at a big tree as thick as five people in front of the mountain, and the arrow used was also specially made, as thick as a small tree, and the arrow was made of pig iron, which had to be 10 pounds. As soon as the arrow passed, the tree was shot through a hole the size of a bucket, and the arrow was nailed directly to the mountain, and the boulders on the mountain were shaken everywhere - the force of the landslide was almost as powerful as a mortar.

Zach held a longbow in his hand, and carried the cast-iron heavy sword that Wang Xika had made for him before, and said happily: "With this bow, I can shoot the sun in the sky, and with this sword, I can also split the earth under my feet." Our race will not be extinct!"
