"Master Hou, that beggar came again last time, and he is waiting for you!" Chen Xu returned to the mansion, and the steward Huang Fu hurriedly greeted him.

"Let's go, go and ask him what information he gets!" Chen Xu nodded and took Yu Wuya to a remote room, where Ma Teng, who was still wearing beggar clothes and a hat, was drinking tea and roasting the fire inside.

"Master Hou!" Seeing Chen Xu come in, Ma Teng hurriedly put down the teacup in his hand and stood up and saluted.

"Well, how's it going?" Chen Xu waved his hand and sat down.

"Master Hou, I have already heard the news, Shang Qi and the others have secretly arranged, there should be at least four of them, two stewards, one supervisor and one craftsman, ready to find an opportunity to burn the grass hut where the workers and slaves live in a few days, causing chaos on the construction site......

"Hey, hey, good!" Chen Xu gritted his teeth with a gritted smile on his face.

For the next two days, Chen Xu spent almost all day and night at the construction site as if nothing had happened, but secretly ordered Yingbu to let the forbidden army closely monitor the few people Gao Teng said, and all the people he came into contact with were firmly stared to death.

Two furnaces of steel have been successfully smelted under the command of Gong Lose, one is low-carbon steel, that is, wrought iron with a relatively low impurity content, which is mainly used to make horseshoes and knife blanks as sabers, and the other furnace has a higher carbon content, which is poured and cooled into strip-shaped steel billets, which are used to make heavy weapons such as spears and knives.

During the Spring and Autumn Period, whether it was China or Rome in the West, ordinary weapons were swords, and the general scribe accessories were mainly one-handed swords, which were very light in weight, about two feet long, mainly for decoration, and could also be used as a simple self-defense.

The swords used by folk samurai are generally three feet long, the blade is narrow, and the weight is three to five catties, which is also one kilogram.

The army is generally equipped with a big sword, the hilt is one foot long, plus the blade is four to five feet long, the sword body is thick, generally more than ten catties, and it can be held with both hands in battle, and because of the low content of lead, plus the appropriate proportion of copper and tin, the toughness and hardness are very good, so the lethality is huge.

According to the analysis of the bronze sword unearthed from the Qin tomb in later generations, because the bronze weapon was cast using rapid cooling measures such as chromium brine quenching, the different internal and external cooling rates led to different content of tin inside and outside the weapon, and the slow cooling rate inside led to the overflow of tin at high temperature, so that the internal tin content is low, and the outside cooling speed is fast, so the tin content is high, so the bronze sword has a certain toughness, not easy to break, and the hardness is also very good, so although China still used bronze weapons in the Qin and Han dynasties, it is much stronger than the sword forged by Roman pig iron. In other words, although Rome used iron swords, it may not be as good as the bronze swords of the Qin Dynasty.

At the same time, the iron sword of the Roman period also has one of the main shortcomings, that is, the swords are very short, because the Roman infantry all have shields, can only hold a shield in one hand and a sword in the other, the length of the sword is generally not more than two feet, that is, about forty centimeters, far shorter than the bronze sword of the Qin Dynasty, at most equivalent to the short sword used by the literati, so the lethality is very limited.

Of course, the soldier swords of the Qin Dynasty were mainly used for self-defense, and the array attack was generally a bow and arrow covering strike first, and then the pikemen rushed into battle.

Since Chen Xu is preparing to develop long weapons for horse warfare, he is naturally ready to install heavy weapons, that is, no matter the spear and sword, they are all prepared to be made of steel, so that with the help of the impact of the war horse in the impact, a strong horse pawn swings a ten-kilogram broadsword, and there may be hundreds of kilograms of impact power.

Legend has it that Guan Yu's Qinglong Yanyue knife weighs seventy pounds, converted into the weight of the next generation is almost eighteen kilograms, plus Guan Yu's people are tall and powerful, and all those who fight with Guan Yu generally die quickly, after five passes and six generals, almost all of them are solved with one or two knives, without him, it is the impact plus the strength, and even people and horses can be split into two pieces with a knife, and the development of heavy weapons to the Tang Dynasty, there is a professional hoplite Mo knife team, the Mo knife is seven feet long, weighs fifteen pounds, can be called the enemy cavalry meat grinder, Moreover, it is extremely time-consuming and expensive to make a Mo knife, so the Tang Dynasty decree stipulates that Mo knives are not allowed to be used as funeral objects.

(Note: a pound of 660 grams in the Tang Dynasty, so a Mo knife also has about ten kilograms, as an infantry can not borrow the state of dancing or need great waist and arm strength, this weight can refer to the shot put, the men's shot put generally weighs 7.5 kilograms, when I was in physical education class, I can feel the weight, very heavy, boys with little strength are estimated to be able to throw two or three meters away, and it is possible to smash feet with less strength.) ）

The main method of the Qin Dynasty to deal with the enemy's cavalry was the spear, which was somewhat similar to the Macedonian spear phalanx, and as for the hand-to-hand combat, it was cut with a sword.

The sword is a weapon with blades on both sides, so it is easy to kill and injure the enemy, but it has great disadvantages, it can only be chopped, and it requires a lot of strength, so after the Han Dynasty, the sword has slowly withdrawn from the armed sequence, becoming a decoration that represents identity, and is replaced by a knife.

Although the knife only has a single edge, it can be used flexibly, both chopping and cutting, as well as stabbing and cutting and other ancillary effects, it is easy to cause trauma to the enemy, so the knife has become the main weapon of the army, in the late Han Dynasty after the steel smelting technology has matured has begun to be equipped in large quantities, but at that time it was mainly the ring head knife, a straight blade and straight back shape, this shape of the knife developed to the peak in the Three Kingdoms period, Liu Bei and other warlord groups are tens of thousands of pieces.

In the Sui and Tang dynasties, the steel irrigation method appeared, and the hundred refining methods of repeated forging were slowly replaced, and the sword has replaced the sword as the main weapon, and even the etiquette has no sword.

In the Song Dynasty, the sword was completely reduced to an ornament or a weapon for martial arts masters, and the scribe with the sword was used as an identity and symbol of respect for the ancient rites, and the Jianghu chivalrous with the sword...... Well, they are generally masters, a little red for thousands of miles, a sword without blood, Dugu Jiujian is synonymous with masters, only the disciples of the big sect use swords, commonly known as swordsmen, and what five tigers break the door knife, the divine knife door, and the golden knife village are all secular sects in the rivers and lakes, walking in the rivers and lakes are commonly known as swordsmen, and the beard and open chest are the most common images.

In the Ming Dynasty, the knife was developed to the extreme, there are dozens of types of knives alone, the sword was completely abandoned, and it was replaced by the Yanling knife, the waist knife, the Japanese knife, the seven-star knife, the ox ear knife, etc., the most famous of which is the embroidered spring knife equipped with the brocade guard.

Before there were no hot weapons, whether on the battlefield or among the people, the knife was the absolute king.

Therefore, among the weapons designed by Chen Xu this time, he directly abandoned the sword, which is suspicious of pretending.

Riding on a horse to fight, in addition to the long weapon, the most convenient is a saber with an arc, a wide back and a thin blade, a slender blade, a bent handle, weighing six catties, not light or heavy, as long as it is waved on the horse, plus the impact of the war horse, the Huns and Donghu, who have no iron armor and are now fighting with wooden sticks and cow bones, are definitely a scum.

And the Great Qin horse pawn also has a sharp weapon, that is, the light horse, it is said that the range can reach eighty zhang, but Chen Xu has tested, it can't reach this far, the farthest is seventy or eighty meters, the effective killing distance is only about thirty meters, the power is almost equivalent to the pistol of later generations, the role of the light horse is mainly to cooperate with the horse pawn to attack and harass the enemy, the lethality is not great, and even in Chen Xu's opinion, it is a bit chicken, because the horse pawn impact speed is fast, seventy or eighty meters rush over in a few seconds, and a photo can only shoot once at most, And because in the high-speed bumpy movement, the blind head, just like riding on a war horse and shooting with a pistol, the psychological intimidation of the enemy accounts for the majority, because once the bow and crossbow are raised, the enemy will subconsciously dodge no matter what state, if thousands of horsemen attack at the same time, there is still a great threat, dense arrows past, there are always some unlucky eggs who are shot and fall, and then cause chaos in the local troops.

Therefore, this time Chen Xu asked Liu Erwa's two apprentices to design and modify the first Takahashi saddle he brought, and took a few recruited carpenters and cobblers to hide in a separate laboratory of the Academy of Sciences After more than half a month of manufacturing, three kinds of saddles have been made, one is for generals with high force value, because it is equipped with heavy weapons, so the saddle is designed to be very strong, with a very strong hook on the side to hang weapons, and the second is a saddle for horses, with hooks on both sides to hang sabers and light horses, The third type is the ordinary saddle, which is relatively simple and lightweight, and has a blanket at the back, which is mainly used to promote civilian use.

The blacksmith shop tinkled and there was a constant sound of banging.

As the chief master of weapon production, he has now summoned more than ten of the best copper and blacksmiths in Xianyang City to be his subordinates, and there are nearly a hundred helpers to assist, so the blacksmith shop is overcrowded.

The bellows were pulled and whirred, the four coal stoves were lined up, a large amount of peat was constantly added to the earthen stove, and the strip-shaped steel billets were sent into the coal furnace to burn red, and then clamped out and placed on the anvil of pig iron casting to knock sparks in all directions.

The hemp pole kept walking around the shed to check the building process of the blacksmiths, stopping from time to time to demonstrate in person, with an extremely serious face, and after the finished weapon was quenched, it was quickly sent to a closed wooden shed next to it, where dozens of helpers were grinding with gravel, and there was a workshop not far away, in which there were carpenters and leathermen who were recruited to make scabbards, handles and other supporting equipment according to the shape of the weapon.

This situation has not stopped for two days and two nights, and no matter day or night, hundreds of craftsmen and helpers take turns to work and rest to build it.

And Chen Xu's design of the standard saber, three-edged gun blade, broadsword machete and other eighteen kinds of weapons based on the drawing of almost all of the created have been created, although in Chen Xu's eyes is very rough and ugly, but can't help but these are real steel weapons, killing people must be as sharp as chopping melons and vegetables.

Because time is short, it is no longer important to look good, the most important thing is practicality, so size and weight are the most important.

Chen Xu carefully inspected the side between several sheds of the blacksmith shop, took out all the weapons that had been polished and assembled, and looked at them carefully, and finally picked out a long-handled machete, a spear, and a saber, and asked the helper to take it and walk out of the blacksmith shop to a special training ground in the construction site.
