When the arrow pierces the body, the barbs of the two wings will firmly hook the closed wound and be difficult to pull out, and the blood groove will be like a vampire bat to draw out the enemy's blood. By the time of the Warring States, the new three-edged wing style made it more difficult for arrows to heal even when they were pulled out, and the corresponding blood grooves increased to six.

Qin arrowheads increased their poisoning lead levels, and like some Qin swords, the surface chromium oxide technology of the Flyover era made some arrowheads enduring.

However, copper is relatively rare, and the Qin Dynasty has tried to make arrow collars with iron, and with the development of the steelmaking industry in the Western Han Dynasty, all-iron arrowheads have also come out.

In the early days, iron arrowheads were cast, apparently reluctant to resist the viciousness of the copper arrow style, but soon found that they were not as sharp as the latter, so they had to switch to forging.

The disadvantage of forging is that the intricate shape of the cast must be discarded in favor of the four-edged blade of an iron sword, but the advantage is more significant, forging will make it much tougher than its predecessors. The bronze arrow exited the stage, and its beginning and end were in the Eastern Han Dynasty.

The first type of forged iron arrow established the basic characteristics of iron arrows before the Song Dynasty - flat quadrangular shape, which was a style conducive to forging. From the Wei and Jin dynasties to the Sui and Tang dynasties, the classification of iron arrows was simple, and the route of development was to make them harder and longer enough to penetrate the increasingly sophisticated iron armor and tear the muscles and bones of the enemy.

The refinement of the types of iron arrows began in the Song Dynasty, which was really an interesting era, while the military and government were weak, military technology was developing by leaps and bounds. The Song Dynasty had an admirable patience to meticulously craft each weapon, and the style of arrows was also refined, such as iron spine arrows, cone arrows, etc., the shapes have been detached from the monotony of flat quadrangular shapes, and have become more professional.

The Southern Song Dynasty opened the curtain of the era of firearms, and the continuous wars against the Jin and Yuan quickly matured firearms and became the force that dominated the fate of the battlefield. However, with the rate of fire and hit rate of firearms still only suitable for firepower coverage, the growth of the arrow sequence continued into the Ming Dynasty, and continued to create more dazzling types and shapes.

Archery was one of the 'six arts' of the Zhou Dynasty and one of the most powerful means of attack in ancient times. In the early days, if a boy was born in the family, the nobles would shoot six arrows to the four directions of heaven and earth to show the world that the man wanted to conquer, which showed his status in people's hearts. During the Eastern Zhou Dynasty, the popularization of composite technology greatly increased the potential energy that could be stored in the bow body, so that people could convert more power into the bow body within the pull range allowed by the physiological structure, and shoot faster and farther arrows.

The extraordinary strength of the ancients is astonishing, and the elite archer can pull a 70-kilogram strong bow, and it is estimated that the effective range should be between 5070 meters, and the longest range is several times more.

Of course, this is also inseparable from the credit of the wrench that began in the Shang Dynasty.

The humble invention of the wrench, however, made it feasible to pull a strong bow and crossbow without the pain slowing down the rate of fire or even cutting the finger. The significance of the wrench to the archer was so great that the princes and nobles of the Qing Dynasty, who started as a horse archer, eventually turned it into a kind of jewelry.

The bow is characterized by its lightness and speed, which made it always occupy the main position of the cavalry long-range weapon sequence until the middle of the Qing Dynasty, and when the development of firearms eliminated the strong crossbow, the bow was still able to play its own strength and be equal to firearms for 400 years.

The development of crossbows in the military field benefited from the invention of composite bows and copper crossbow machines, otherwise with their shorter pull, they could not compete with the lethality of the bow. The crossbow is characterized by being far and accurate, and there is time to aim calmly, but winding is more laborious and time-consuming.

Based on these characteristics, crossbows are often used for defense and ambushes, and the continuity of firing depends on the rotation of several groups of shooters.

However, there are exceptions, such as the wheel tactics of the Tang Dynasty cavalry. During the Warring States period, the crossbow became a major problem for the chariot, and the powerful lethality of long-range strikes overshadowed the chariot's sturdy shield armor.

However, strong was not the only direction of development of crossbows at that time, and crossbows that were light enough had another advantage in simplifying the firing steps to increase the rate of fire, so a mini-repeater with an arrow magazine and movable arm appeared, which can be regarded as the predecessor of the Zhuge crossbow.

The Western Han Dynasty had a profound influence on the development of strong crossbows. Not only on the basis of increasing the Wangshan in the Qin Dynasty, but also adding a scale, so that the crossbow has a stable ballistic reference, and with the replacement of the wooden crossbow profile with the copper crossbow profile, the crossbow body's bearing capacity to tension has also been greatly enhanced.

The maximum pulling force of the rowing machine-like waist crossbow can reach 370 kg, which is simply incredible, and the effective range is more than 500 meters, but unfortunately it is rarely used after the Han Dynasty because it is not as practical as the arm and pedal tension.

In the Three Kingdoms period, Zhuge Liang made the Yuan Rong commonly known as the Zhuge crossbow in order to fight against the powerful cavalry of the Wei State, and the name of Yuan Rong came from a kind of main general chariot in the Spring and Autumn Period, and the descendants referred to the meaning of the general.

The most alluring thing about Yuan Rong is that it is clever rather than practical, although it is short-lived, but the ingenious design of the wind arm to shoot 10 poison arrows quickly has become an ancient legend talked about by contemporary people.

The woods are actually not far from the avenue, as long as you run fast enough and timely enough, you can say that you can escape into it in an instant. But He Qi is the one who won't let go even in an instant.

"Da-da-da... Da Da... Da-da-da..."

He Qi's M16A4 appropriately spat out a long string of tongues of fire, which contained bullets that could kill people.

All the bullets landed on one of the enemies, allowing him to successfully contribute his own box. And because Lao Hei shot in advance, he still let another person escape into the woods.

"Oh..."

He Qi didn't think about it this time, but threw the shoe directly at Lao Hei, and when he saw He Qi throwing shoes at Lao Hei, the pony also threw a shoe at Lao Hei with hatred.

"Oh, you two are not good descendants, but your wings are stiff and yellow, right? Lao Tzu, you dare to throw it? And it's still throwing shoes! ”

"Shut the fuck, look at the good things you did, originally He Qi took nine out of ten double kills, and let you let one go." Before He Qi could speak, the pony first scolded Lao Hei for He Qi.

Lao Hei also knew that he was wrong, and he stopped talking after muttering twice.

"Shhh

He Qi made a silencing gesture and pulled them all back to the battle situation that they should be paying attention to.

There was a soft sound of metal bottoming out, followed by a long "Boom...", followed by a thick cloud of smoke between the woods and the building where He Qi and the three of them were.

The corners of He Qi's mouth rose slightly, and he put on his usual evil smile, looked at the smoke, and said to himself: "Hmph, it's a little interesting." ”

Why did He Qi laugh at the other party so much, it was because the other party actually played He Qi and played the rest.
