Wang Xiaofei has been stationed in Li Yuanfang's army for three months, these three months are really a hellish life, in Longmen Town, outside Luoyang City, Wang Xiaofei led 5,000 men and horses stationed here, these 5,000 elite soldiers are the elite of the elite he carefully selected from Li Yuanfang's 200,000 army.

Longmen Town has always been a battleground for soldiers, because it is close to Luoyang Shendu, it is about six kilometers, and it will go directly to Beijing after passing here, so Li Yuanfang's army is stationed not far from Longmen Town, in case of sudden changes!

After three months of devil training, these 5,000 men and horses were trained into steel troops, 2,000 infantry, 1,000 sailors, and 2,000 cavalry. Wang Xiaofei is not good at cavalry special training, but he is a smart person, he has learned lessons from the experience of killing the enemy in battle, and repeatedly studied the actual combat skills of the cavalry.

At that time, it was the era of cold weapons, and Wang Xiaofei was not engaged in weapon manufacturing, so without machinery and equipment, he couldn't develop a gun! But at that time there were bows and arrows, and when there was war, there were strong bows and crossbows. The Tang Dynasty was the heyday of China's feudal dynasty. It has expanded to an unprecedented extent, reaching Siberia in the north, the Pamirs in the west, and the islands of the South Sea in the south. This is naturally inseparable from the combat effectiveness of the Tang Dynasty army. The Tang army was dominated by light infantry and cavalry, emphasizing mobility, and bows and crossbows were used as the main long-range weapons to equip most of the Tang army. According to the Taibai Yin Sutra, the number of the Tang Dynasty army was 12,500, equipped with 12,500 bows (37,500 strings and 3,750,000 arrows) and 2,500 crossbows (7,500 strings and 250,000 arrows), with equipment ratios of 100% and 20% respectively. The armament of bows and crossbows overlapped, and some soldiers were equipped with both bows and crossbows. The bows of the Tang army are divided into four types: longbow, horn bow, slight bow and checkered bow, longbow for infantry, angular bow for cavalry, and slightly bow and checkered bow for the imperial forbidden army or hunting. There are 7 types of crossbows: arm tension crossbow, horn bow crossbow, wooden car crossbow, large wooden car crossbow, bamboo pole crossbow, large bamboo pole crossbow and Fuyuan crossbow. The arm crossbow and the horn bow crossbow belong to the light crossbow, which is used by individual soldiers, and the rest are heavy crossbows, such as the big wooden car crossbow, which needs to be opened with a winch, and the tail feathers of the arrow are made of iron, and when the arrow comes out, "the sound is like thunder". In addition, there is a kind of crossbow that is also set on the winch, which can fire 7 arrows at the same time, which can shoot 700 steps, and all the fortresses in the city can be destroyed. These heavy crossbows are too bulky and slow to fire and are not suitable for field combat, so they are generally only used in siege and defense battles. The bow was not a controlled weapon in the Tang Dynasty, and the crossbow was absolutely forbidden to be owned by the people, in order to prevent the peasant rebels from using it against the imperial court.

Wang Xiaofei has a great interest in this thing, he has played with modern crossbow guns, and the crossbow guns equipped by special forces for special forces can reach a distance of up to 200 meters, but this refers to the distance reached under the condition of no large air resistance, under normal circumstances, it can reach an effective distance of 180 meters.

But in ancient times, in the Great Zhou Dynasty, there were only crossbow arrows, no crossbow guns, and the longest distance was 70 meters, which was a portable weapon equipped with archers, and the big crossbow arrows needless to say, the crossbow arrows used in the siege of the city could also destroy the city wall!

Wang Xiaofei is on the original basis, improved the crossbow arrow, turned into a crossbow gun, using the principle of spring stretching, the side of the early crossbow gun installed a rocker, using the principle of lever to stretch the spring to the maximum, and then shoot out, it can reach about 150 meters! It's amazing!
