In other words, the crossbow machine is a bow equipped with organic expansion, although its purpose is the same as the bow, but it does not need to pull the bow manually, and the arrow is ejected with the help of a mechanical trigger, so the range is longer, the lethality is strong, and the hit rate is high. The crossbow machine was produced in the Zhou Dynasty, and it was widely popular in the Warring States Period, and the Qin army, which dominated the world, was famous for its Qin crossbows. Zhuge Liang is good at ingenuity, in addition to inventing the wooden ox and flowing horse to transport grain, he also transformed the crossbow machine of the Qin Dynasty and designed a new type of crossbow machine, called "Yuanrong crossbow", also called "Zhuge crossbow".

Ten iron arrows can be placed in the crossbow trough of "Yuan Rong" at a time, and the arrows are eight inches long. Every time the trigger is pulled, one can be shot, which can be fired ten times in a row, greatly increasing the firing speed of the crossbow machine, which can form a dense arrow array fire covering network for the enemy, and can aim at the target and wait until the need to fire, which is conducive to capturing the timing of shooting, and the hit rate is higher than that of the bow and arrow, which is simply a special weapon of Shu Han. Zhuge Liang also transformed the size of the crossbow machine, including a large repeater machine installed at the head of the city to defend the city, and a light crossbow machine that can be carried by individual soldiers to adapt to different combat conditions.

It's just that the "Yuanrong" is very delicately constructed, and it is especially difficult to make. Only geniuses like Zhuge Liang were able to conceive the drawings, which were then created by Pu Yuan, a famous craftsman in Sichuan. Zhuge Liang ordered Pu Yuan to be brought to Chang'an, recruited a group of skilled craftsmen, plus a thousand sergeants, and began to build repeater machines day and night for future use. The first batch of 300 crossbows were given to Huo Yi Huang Chong, the general of Pujin who had no danger to defend, but he did not expect to show his might in the first battle.

The Wei army camp on the other side of Pujindu

Qin Lang, the general of the cavalry, heard that the Wei army was defeated and the commander Xiahou was killed in battle, he was shocked and angry, and immediately took the case, wanting to lead the troops to attack the key points again. Shaofu Yang Fu on the side hurriedly stopped and said: "General, don't worry, the Shu army is quite strange in this battle. According to the soldiers who fled back, the Shu army used a special bow and crossbow, and our army was caught off guard, so it was defeated. ”

It is said that Yang Fu, whose name is Yishan, is a famous minister of Cao Wei, who once defeated Ma Chao with a trick and gave him the title of Marquis of Guannei. When Emperor Cao Rong of Wei Ming, he served in the imperial court, and he had both ability and political integrity, and was upright. Cao Rui was worried that Qin Lang, the favorite general of the Northern Route Army, was not resourceful enough and had some accidents, so he sent Yang Fu to Qin Lang's army to serve as a member of the army and give advice.

Qin Lang stopped when he heard this, and Yang Fu continued: "The bow and crossbow used by the Shu army are extraordinary. First, its range exceeded 100 paces, which greatly exceeded that of ordinary bows and arrows, so our army thought that it was not within the range and was unprepared and was raided. The second is that it has a fast firing speed, and quickly forms a dense array of arrows, which is incomparable to ordinary bows and arrows. Third, it has a high hit rate, and there are almost no missed shots. Fourth, its lethality is strong, and it can still penetrate shield armor at a distance of 100 steps. ”

Qin Lang was shocked and said, "There is actually such a divine weapon in the world? ”

Yang Fu said gloomily: "I heard that Zhuge Liang is good at ingenuity and is good at invention, in addition to the wooden ox and flowing horse, he once invented a crossbow machine called "Yuan Rong". This kind of crossbow machine not only has a long range, high hit rate and strong lethality, but also can fire ten arrows and crossbows in a row, which is very powerful. Could it be that the Shu army is using this kind of repeater machine today? Yang Fu thought for a moment and sighed: "It must be!" The crossbow machine is the most suitable for defending the city, and the Shu army has been mainly attacking and fighting before, and it has not been used. Now guarding Pujin Pass, there is no danger to follow, and Chang'an behind it is related to Liu Chan, the lord of Shu, according to today's situation, the Shu army must have "Yuan Rong"! ”

Qin Lang didn't pay attention for a while, and he didn't dare to tackle the problem, staring at Yang Fu with blank eyes, and asked eagerly, "How is this good?" Yang joined the army and had to quickly find a way to deal with the "Yuan Rong" of the Shu army! Otherwise, if we fail to tackle the key problems, and lose our troops, Your Majesty will definitely blame! ”

Yang Fu is worthy of being a wise man, and after thinking for a while, he said with a smile: "The art of war is cloudy, avoiding the real is false." The "Yuan Rong" is so powerful that our army cannot attack it by force, and we should try to avoid its threat and make it difficult for it to exert its might. According to my observations, the Pujin Pass is very open, and if our troops quietly move to the open area below the pass at night, quickly disperse, and attack key problems from many places, the threat of "Yuanrong" can be greatly reduced. ”

"What a plan!" Qin Lang clapped his hands and laughed, "Yang Senjun is really resourceful, no wonder even Jin Ma Chao was defeated by your strategy." According to Yang's plan to join the army, he ordered the three armies to immediately return to the camp to eat and rest, and wait until after dark to launch an attack! ”
