After Zhang Fan arrived in Jing County, he did not immediately start a war with Zu Lang, but the whole army was stationed in Jing County, and craftsmen were gathered in an orderly manner to start making siege ordnance day and night. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

If you want to do a good job, you must first sharpen your tools.

Science and technology are the primary productive forces, and Zhang Fan's biggest advantage is the knowledge that is more than 1,000 years ahead of the times.

As the attacking side, and the situation that the number of people is at an obvious disadvantage, the reason why Zhang Fan resolutely launched an offensive against Zu Lang is of course not because he is blindly confident that all of his subordinates can be a thousand, but because the first victory battalion itself occupies a huge advantage in weapons and equipment, which will infinitely narrow the gap in numbers.

The armor and weapons of the Shanyue soldiers are all produced by themselves, the materials are poor, the technology is backward, and the craftsmanship is rough, not to mention that compared with the soldiers of the Shousheng Battalion, it is simply the gap between millet rifles and cannons. Even compared to the average large bandit, it is much inferior.

Zhang Fan not only has a solid family background, after all, his business cooperation with Zhen's family has allowed him to accumulate a lot of wealth. And he never picks the door, and is willing to use all the good steel on the blade. From weapons to armor, whether it is workmanship or material selection, even if you look at the entire Jiangdong and even the whole territory of the Han Dynasty, it is one of the best.

Since Zhang Fan came to power, he sent people to visit skilled craftsmen all over Jiangdong. Then the strategy of using money to open the way, the policy of sticks and carrots, recruited thousands of skilled craftsmen, and secretly developed a variety of new weapons and equipment in the back mountains of Huanglongzhai.

Although Zhang Fan himself does not know how to make, there are many mechanical, instrumental, engineering mechanics, civil engineering, surveying and mapping, chemical industry, and pharmaceutical among the sailors...... and other high-end compound talents in various related industries, they are also happy to help Zhang Fan invent and transform various weapons and siege equipment, and this sense of participation also makes them happy.

With the assistance of the sailors, Zhang Fan and the craftsmen worked together to come up with a lot of good things, in addition to the wheel bow and the super trebuchet that exerted their power last time, there were also a few good things that might help Zhang Fan change the tide of the battle.

The first is the Divine Arm Crossbow, with a bow body length of three feet and a string length of two feet five, and a range of more than 340 paces, which is claimed to be beyond the reach of other instruments.

Shenzong was introduced to the Northern Song Dynasty and became one of the standard weapons of the crossbowmen of the Song army. The Divine Arm Crossbow is equipped with a mechanism, but it can be fired by one person, has a range of up to 400 meters, and can penetrate heavy armor, which makes the Jin army fearful.

The god arm crossbow uses tough mountain mulberry wood as the crossbow bow, and uses solid sandalwood as the crossbow body, hemp is the string, light and strong, the history books record - the god arm crossbow takes the mountain mulberry as the body, the sandalwood is the bow, the iron is the gun chamber, the steel is the machine, the hemp rope is the string, and the silk is the string. The effective range is more than 240 paces, or more than 372 meters.

Crossbows have four advantages over ordinary bows and arrows. First, the firing range is long. A crossbow requires more force than a bow when it opens its strings, so it has a longer range than a bow.

Second, the hit rate is high. A crossbow is actually a strengthened bow and arrow, which can be aimed at the target and waited until it is needed before firing, which is conducive to capturing the timing of the shot, and the hit rate is higher than that of the bow.

Third, it can fire several or even dozens of arrows at the same time, and the combat power is strong. So, a crossbow is more practical than a bow.

The last point is that the crossbow is more lethal. The armor-piercing effect is significant.

In fact, why did some generals in ancient times still kill all sides like hedgehogs with arrows stuck in their bodies on the battlefield? That is, arrows cannot break the armor, and generally important generals do not only wear a layer of armor, but also inner armor in addition to the outer armor. It is possible that the arrow only gouged through the outer armor and got stuck, so it did not cause effective damage.

Of course, the disadvantages of crossbows are also obvious, the first point is that the crossbow machine is very bulky, not as easy to carry as a bow and arrow, and is generally made into a car crossbow and a bed crossbow. The second point is that the production process is complex, the production cycle is long, and the cost is high.

For these two reasons, archers are the standard in the army, and crossbowmen are generally a rare and special type of military.

Of course, these two points are not a big problem for Zhang Fan, first of all, he is not short of money, and the technology ahead of the times can greatly reduce the production cost and cycle. In particular, the Divine Arm Crossbow made without affecting the performance, greatly reducing the size and weight, making it easy to carry and can be used for individual combat.

In addition to the divine arm crossbow, Zhang Fan led the craftsmen to develop another magical crossbow - Zhuge Repeater.

Zhuge repeater is a kind of crossbow made by Zhuge Liang during the Three Kingdoms period, also known as the Yuanrong crossbow, which can fire ten arrows at a time, and the firepower is very strong, but the volume and weight are too large to be used by individual soldiers, and it is mainly used to defend cities and camps.

Ma Jun, a great inventor at the end of the Han Dynasty, wanted to improve it and make it a kind of fifty-arrow crossbow, which was more powerful, but because the production was very complicated and the arrows used had to be specially made, it was not produced in large quantities and was later lost.

Yuanrong crossbow is the earliest name of Zhuge repeater. According to the record: "The profit and loss crossbow, called the Yuan Rong, uses iron as the arrow, the arrow is eight inches long, and one and ten arrows are fired."

This kind of crossbow is an improved crossbow based on the original repeater by subtracting unnecessary and useful ones, and after the transformation is completed, it is awarded the name "Yuan Rong", that is, the meaning of marshal.

Zhuge Repeater is a copper crossbow machine, and the same as the general crossbow machine, with an outline, a hanging knife, a cow, a pivot, a lookout mountain and teeth, but its size is much larger, the copper profile of the crossbow machine is thirty-nine centimeters long, and the total length of the hanging knife is nearly twenty centimeters.

The length of the wooden crossbow arm on which this large crossbow machine is mounted is at least about 180 to 226 centimeters, while the length of the crossbow used is nearly 430 to 540 centimeters.

It seems that such a huge crossbow can only be opened by installing it on the bed and can be opened by means of a winch, which is called a "divine crossbow".

Zhang Fan was satisfied with the power after copying the Zhuge Repeater, but the huge size was the flaw. Since the original plane could be modified into a single weapon, of course he had to try.

With the unremitting efforts of the Tea Division, a month ago, the intelligence officer of the Tea Division finally found the person who was very critical to the improvement of the Zhuge Repeater in Fufeng County - Ma Jun.

Ma Jun, whose name is Deheng and Fufengren, is one of the most prestigious mechanical inventors in the history of ancient Chinese science and technology.

Ma Jun's family was poor when he was young, and he had a stuttering problem, so he was not good at talking but was good at ingenuity, and later held an official position in the Wei State. After the guide car was made, he was edicted to make a hundred puppet plays, called "water turns a hundred plays". Then Ma Jun transformed the weaving machine to improve the work efficiency by four or five times. Ma Jun also improved the keel waterwheel (overturner), a tool used for agricultural irrigation, and after that, Ma Jun also reformed the Zhuge crossbow, which contributed to the development of science and technological progress.

For this kind of technical nerd, Zhang Fan only used a few design drawings of the Zhuge Repeater, and successfully pried him to Huanglongzhai and successfully joined his own camp.
