Heavenly Spirit Continent.

Qingyuan Village.

When Mo Mo waited for the earth time to reach the early morning, he traveled to the other world again, and at this time, Qingyuan Village was early in the morning.

The last time he transferred goods to the other world was during the second medicinal bath, and it had been more than ten days since today, and he had instructed Shi Wu to sell out the goods he had moved over last time and take a break for a while.

Mo Mo came to the village and soon met Shi Wu, and the two went back to the house to talk.

It has been two days since Shi Wu came back from a long trip, and he told Mo Mo about the situation of the goods transaction, and the two long journeys sold a total of nearly 2,000 gold coins, plus the two hundred gold saved before, a total of 2,200 gold coins, according to Mo Mo, he did not purchase the array spirit stone for the time being.

Recently, there have been some changes in Qingyuan Village.

Mo Mo first gave Shi Wu two hundred gold coins for labor services, and asked him to purchase the materials needed by the whole village first. The purchase cost of 25 white horses and weapons was included in Mo Mo's head, and the team grew to 20 people.

What makes Mo Mo distressed is that otherworldly steel is nearly ten times more expensive than the earth, half of the price of copper, it is estimated that it is related to smelting technology, and the smelting temperature of steel cannot be reached, after all, the melting point of steel is more than 1500 degrees Celsius, which is more than 400 degrees Celsius higher than pure copper, and it is difficult to smelt higher. This situation is similar to the development of smelting in ancient times on Earth, but the demand for steel in the other world is greater, resulting in extremely high steel prices.

That is, their ironmaking process is still at the level of block ironmaking (ironmaking uses charcoal as fuel, with less heat, plus the furnace body is small, and the blast equipment is poor, so the furnace temperature is relatively low, and the smelting temperature of iron cannot be reached, and it is called block ironmaking, which is relatively soft in texture and contains many impurities, and is forged into wrought iron with a carbon content of less than 0.02%)

The best steel in the other world is 100 steel, that is, in the process of forging block iron and wrought iron, it needs to be heated repeatedly, and the iron absorbs the carbon in the charcoal, improves the carbon content, and reduces the inclusions to become steel. A piece of steel often needs to be burned, and repeated many times, or even hundreds of times, so it is called 100 steelmaking.

The normal market price of a ton of steel in the other world costs 7 gold coins for a block of iron, 8 gold coins for wrought iron, 9 gold coins for general steel, and 10 gold coins for 100 steel smelting.

With such a high price, Mo Mo speculated that there was no steel frying process in the other world, not to mention the more advanced technology of steel filling (which was common in the 16th century on the earth), the sugang method, and even the blast furnace ironmaking of the earth's modern technology (which appeared at the end of the 19th century on the earth), and open-hearth converter electric furnace steelmaking.

In short, a 30-kilogram ordinary steel knife, plus the manual production cost, will require 2,000 copper coins, which is 1,000 yuan. It costs 2,500 steel coins to exchange for a 100-steel knife of the same weight, which is an increase in the cost of the worker, after all, the less impurities in the material, the more expensive it is.

In exchange for the earth, it is only more than 3,000 yuan a ton of ordinary steel (the ex-factory price of general tool steel), if it is to make knives, plus labor costs, it is estimated that 30 pounds of ordinary steel knives are better than 100 steel knives in the other world, and they are less than 100 yuan.

Therefore, Mo Mo has the idea of finding a mine to make steel and iron, perhaps it is safer and more assured than selling the earth's goods, after all, there are many people who use iron in the other world, such as kitchen knives, pears and other agricultural tools, construction nails, axes, knives and guns and other weapons, saws and chisels and other wooden tools、...... There are some in every household.

Besides, he purchased a large number of watches and steel knives on the earth, and the amount was large, and he was really afraid that it would cause people to investigate it deeply.

Of course, for Mo Mo, steelmaking and ironmaking are too far away at present, and he should settle down before thinking about it.

"Recently, there have been Qingyu soldiers who have come to the village to search twice, and the portrait looks very similar to you, and it just so happened that our people met them, and they were all more clever, and they all said they hadn't seen it. Shi Wu said with some concern, it is not a good thing for officers and soldiers to find people, and it is also a Qingyu army with a combat strength of more than 300.

Fortunately, the officers and soldiers did not ask other villagers, and left in a hurry, if the faces of the villagers who answered changed, even if they said that they did not know, it was estimated that it would arouse the suspicion of the Qingyu army.

Mo Mo was frightened, his face changed slightly, and at the same time, he was full of doubts, and asked, "Uncle Wu, it's impossible for the bandits to invite officers and soldiers, right?"

"The bandits are not in a hurry to come to the Qingyu Army, and I can't figure out why they are looking for you. ”

"I'm also very strange, I haven't offended anyone!" Mo Mo couldn't figure it out, he was confused for a while, and an ominous premonition surrounded him.

He didn't stay in the Heavenly Spirit Continent for a long time, and he went to Qingzhou City once, and he didn't seem to offend anyone there.

"Uncle Wu, stop going out for the time being, I'm afraid that there will be a shocking change in the village. ”

The officers and soldiers went directly to the village to search twice, and Mo Mo suddenly felt the importance of improving his force, and he didn't know why there were officers and soldiers to search for him, or the Qingyu Army. If the Qingyu Army really wanted to destroy Qingyuan Village, the whole village would have no ability to resist at all, and let others eat and drink.

As soon as Mo Mo thought that Qingyuan Village might be slaughtered, his palms suddenly sweated, and his whole body became cold. He has feelings for Qingyuan Village, and the Shiwu family treats him as family, and other villagers treat him very kindly.

Blindly trying to make money attracts the greed of others, and he does not have enough strength to protect his money, so he can only make a dowry for others in the end.

Mo Mo asked bluntly: "Uncle Wu, I saw your big bow last time, do you have any more advanced bows and arrows?"

During this time, Mo Mo learned about some of Earth's traditional weapons, such as bows and crossbows.

There are many types of earth bows, which are mainly divided into three categories: traditional bows, modern recurve bows, and modern compound bows.

Traditional bows and recurve bows are difficult to learn, have a fast rate of fire, and are suitable for continuous charges;

The compound bow is easy to learn and the fastest, powerful, and high-precision, suitable for hunting and sniping, but the structure is complex, the rate of fire is slow, and the requirements for arrows are high.

Each of the three bows has its own advantages.

Shi Wu took off his big bow from his back, Mo Mo carefully examined it, this kind of bow is similar to the shape of the earth's traditional horn bow, which is composed of three parts: wood, horn and tendon, but Shi Wu's bow body material is different, thicker and larger, the arrow shaft is also thicker, and the bowstring is made of beast tendons.

Shi Wu explained: "The materials used in the bows are similar, and the bow body is mostly made of birch wood with a dense texture, smooth and elastic, and the good ones are made of hard gold wood, which takes a longer time to make, but the tension is different."

This bow is a hunting bow bought in the city, the accuracy and range are average, suitable for strength and combat effectiveness between 60 and 100, 2000 copper coins, in fact, it is similar to the bow made by yourself, that is, the bow making cycle is too long, and the wood should be put for a year or two, but I am afraid that it will be too dry and easy to break, and it will be too wet and the strength is not enough.

Unless I use an expensive iron tire bow, the greater the strength (pounds), the more expensive it is, but the iron pieces are also easy to break, and they are all bows of more than ten stones, and I can't pull them. ”

The strength and combat effectiveness are 60 to 100, and the clean and jerk strength is 180 kg to 300 kg, while the men's 56 kg world clean and jerk record on earth is 168 kg, and the 105 kg world clean and jerk record is only 263 kg.

In this way, Shi Wu's big bow is really unusable for earthlings, let alone the iron tire bow.

A normal person pulls a 50-pound (45-pound) compound bow and is exhausted after several pulls. It is estimated that Shi Wu's bow, if calculated according to the number of tenacities, is between one or two hundred pounds, and the earthlings have to step on the bow body with their feet and pull the bowstring with both hands to pull it.

The greater the tension of the bow, the stricter the rigidity requirements for the arrow shaft, otherwise it is easy to explode arrows and hurt people.

Mo Mo picked up an arrow and weighed it, feeling heavy, weighing one or two hundred grams, and the wood was also very hard.

As for the iron tire bow, ten stones is 600 kilograms, and Shi Wu really can't pull it.

"Uncle Wu, how far is the effective range of the big bow?" Mo Mo asked.

"It's about 120 steps, and if it's about the lethality of wild beasts, it's estimated that it's only seventy or eighty steps. Shi Wu explained.

"120 steps, this is only sixty meters away!" Mo Mo felt a little unconvinced, thinking that there should be hundreds of meters.

The system explains: "Host, a large pull force does not mean that the arrow has a long range, it mainly depends on the kinetic energy E = 1/2 mv2 caused by the pull force, the greater the muzzle velocity, the farther it is, the greater the weight of the arrow, the lower the muzzle velocity." At the same time, as the shaft of the arrow becomes thicker, the greater the air resistance, and the decrease in speed increases dramatically. If the rigidity of the shaft is poor, it will vibrate and the speed will drop dramatically during flight. ”

The system also told Mo Mo that if it was a 50-pound compound bow, with a 400-gram arrow shaft (26 grams), a steel arrow, and a hardwood 60-meter-away shot depth of up to 4 centimeters, which was twice the killing range of the Otherworldly Great Bow.

Blindly reducing the weight of the arrow, failing to meet the deflection requirements (poor rigidity), when the bow is drawn, the arrow shaft will be crushed and broken by the huge thrust of the bowstring before it can be shot out (exploding arrow), and the broken arrow shaft will most likely be directly inserted into the bow bearer.

If you are not careful, you may even get it into your eye.

Playing with a compound bow is not so safe.

"Uncle Wu, if there is a bow that says it shoots farther, has more destructive power, and is easier to pull, what do you think?" Mo Mo asked, seeing how he answered.
