Chinese catapults first appeared in the Warring States period, when they were still very rudimentary. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 To put it bluntly, it is to use the elasticity of the wooden pole to insert a long wooden pole into the ground and fix it, and then use human power to pull the top of the wooden pole downward and bend it, and then load stones, poisons, animal carcasses, etc. As soon as everyone let go, the elasticity of the wooden pole itself tosses the heavy object, and the effect of a catapult is achieved.

Later, after development, it evolved into a place far away from the catapult to pull the pins attached to the crossbar (cannon pins, erected on a wooden frame, one end is tied with a rope to hold the leather case containing the stone projectile, and the other end is tied with many ropes to facilitate human pulling) to throw the stone projectile, divided into single and multiple pins. The maximum number of shoots is 13, and a maximum of 500 people are required to cast them.

The thunderbolt car mentioned by Li Fugui is the product of the continuous development of trebuchets since the Warring States period, and was designed and manufactured by Cao Wei during the Three Kingdoms. Specifically, the thunderbolt and the stone machine that Zhang Jun is going to use now are not the same thing, but because the torsion stone machine has not yet been named, it is still called "thunderbolt".

"Squeak ······"

"Squeak ······"

The four-wheeled "thunderbolt" was pushed up by a dozen soldiers, and there was a flat place at the top of the mountain, where it stopped. The sergeant used a boulder to clamp the four wheels to the main one so that the thunderbolt would not shake, and then began to arrange them in an orderly manner.

Zhang Jun and his generals stood not far away, this thing is still a new thing, everyone is very curious, even Zhang Jun himself showed a very interested look.

I saw Li Fugui introduce as if offering a treasure: "Governor, colleagues, the thunderbolt is different from what was produced in China in the past, and its special feature is that it developed from the bow, which is also known as the stone crossbow, that is, the crossbow that fires stone projectiles. It has been widely used in warfare in Daqin, but this one is still the only one in China. “

Seeing the soldiers operating on the side, Li Fugui took the opportunity to continue: "Metropolitan Governor, please see, this new thunderbolt car relies on twisted ropes to generate power ejections. The ejection rod is usually upright, the top of the rod is a "spoon" or leather bullet pouch for the projectile, and the lower end of the rod is inserted in a tightly twisted horizontal rope. When ejecting, the ejection lever is first pulled to a near-horizontal position with a winch, and the projectile is placed in a "spoon" or leather bullet bag. When the winch rope is released, the ejection lever returns to a vertical position to eject the projectile. ”

Zhang Jun nodded, signaling that he understood, but the other generals were still confused.

"Fetch a bow!" Seeing this, Zhang Jun commanded.

A moment later, a longbow was handed over to Zhang Jun by the guard, and he felt that one bowstring was not strong enough, so he asked the guard to take another one and hang it on the bow, so that the bow had two strings. Zhang Jun pulled out a feather arrow, inserted it between the two bowstrings, and then rotated it repeatedly until the two bowstrings were twisted into a twisted shape and could no longer rotate, and then pressed the arrow on the shaft, and then twitched the shaft of the arrow again so that it could be blocked by the bow, and finally suddenly let go.

"Stretch!" With a soft sound, the feather arrow popped out quickly under the action of the torsion of the two bowstrings, and finally shot at a big tree a few feet away, and it turned out to be three points out of the wood!

"Do you understand?"

Zhang Jun casually threw the bow and arrow to the guards, looked at the stunned subordinates with a smile and said: "There is a theorem between all things, it is not the specialty of the Great Qin people, we Chinese people can also do it!" ”

"The Metropolitan Governor is mighty!" Li Fugui knelt on the ground and shouted loudly.

Although the others were not ashamed of this big fat man's behavior of slapping his ass, they all crossed their hands and bowed convincingly: "The Metropolitan Governor is mighty!" ”

Hu Shuo was even more exaggerated, and shouted while touching the thunderbolt car: "Mother, this is a baby!" ”

Seeing that his move had interfered with the work of the soldiers, Zhang Jun couldn't help laughing and scolding: "You fool, you won't come back yet!" ”

"Metropolitan Governor, this thing is indeed a militaristic weapon!" Wang Meng also roared, and his face was full of ecstatic expressions, as if he had seen the scene of countless Hun iron horsemen being smashed into meat cakes by countless stones falling from the sky.

He couldn't help but say: "If there are thousands of such sharp weapons, the last general is willing to be the forerunner and recover the two capitals!" “

Zhang Jun smiled and said unknowably: "Don't be too happy too early, what is the range and rate of fire of this thing, it remains to be observed, let you come here today, just let everyone see." If it's really useful, then the conquest army will be equipped with it in the future. ”

Let's not talk about how calm and relaxed Zhang Jun is outside, on the other hand, inside the courtyard, there is already a scene of chickens flying and dogs jumping······

Xin Jing, as the steward, didn't care about fooling around with the maid after learning the news, hurriedly put on his cloth shoes and rushed to the front yard, grabbed Charin and asked, "Sect leader, what's the situation?" ”

Charin was already dissatisfied with this so-called steward, and when he saw him in horror like this, he was even more disdainful in his heart, and when he shook off Xin Jing's hand, he said in a deep voice: "Outside is the government army and the conquest army of Guangwu County, there are about two thousand people. ”

Observing the number of enemy troops is a technical task, if it is not for the experienced scout scouts, it will never be able to see, if it is really a number, then I am afraid that after the battle, how many people on the opposite side still do not know.

When Xin Jing heard that there were 2,000 people outside, his legs and stomach suddenly turned, and he shouted in panic: "Prepare the horse, check the head of the sect, quickly prepare a horse for me!" ”

His shout attracted everyone's attention, and everyone was still the same enemy, but now when they saw that the steward had to run first, half of their morale was immediately discouraged.

Charing was furious, rounded his arms, and opened his bow left and right, "Smack!" Syllable! It was two big slaps, which made Xin Jing's face swollen and his nose bloody.

Xin Jing was beaten, he covered his face, pointed at Charin and said in a trembling voice: "I understand, you are a spy, come on, he is a spy, take it down for me!" ”

Charing's anger surged, and without saying a word, he directly drew out his knife and flew Xin Jing's head out of the air. He looked at the group of subordinates who were at a loss and shouted, "Steward Xin has shaken the morale of the army and has been killed. If you don't fight to the death, this will be his fate! ”

The nurses were already under Charin's orders, and besides, Xin Jing was dead, who would care about him. At the moment, they all received the order and decided to break the net with the government army outside.

But at this moment, a strange "Woo! The sound of the earth suddenly came from the sky, and the nurses in the courtyard couldn't help but look up, only to see a stone the size of a cold melon falling from the sky. No one took refuge, because the big stone fell on the ground more than a dozen paces away in front of the main gate of the courtyard, and after tumbling for a long distance, it slammed into the gate with a thud.

"Li Fugui!"

Outside, Han Hu said angrily when he saw this: "How did you do it, you can't beat such a big yard?" ”

Zhang Jun waved away Han Hu, stepped forward in person, and said to Li Fugui: "You stand aside and watch!" ”

With that, he stretched out his thumb and raised his right arm horizontally, with his thumb straight up and his upper arm perpendicular to his body. Then close your left eye and aim (occlude) the object with your thumb by rotating your waist. At this time, the right eye, thumb, and the object are in a line. Immediately afterwards, Zhang Jun closed his right eye again and opened his left eye. At this point, the object is seen to appear on the left side of the thumb, at a lateral distance. Estimate the size of the object to be measured. According to the size of the measured object, the lateral distance from the measured object to the position pointed by the thumb is determined. Multiply this lateral distance by 10 to get the distance of the object from us.

That's right, what Zhang Jun used at this time was a method of estimating distance commonly used by our military in later generations - the eye-jumping method!

When the ranging was over, Zhang Jun instructed the soldiers to adjust the angle of the thunderbolt and wait until he gave the order······

"Bang!" With a bang on the ground, another boulder rose into the air, drawing a perfect parabola, "Boom! "The ground slammed down on the gate of the courtyard two hundred paces away!
