Zhou Tai's incident is not an isolated case.

In the fourth year of Chuping, Kong Rong, the prime minister of Beihai, was very surprised when he heard about Taishici's past, so he sent people to ask about Taishici's mother several times and gave gifts to him.

The Yellow Turban surrounded the city, and the mother sent Taishi Ci to help.

After the work was over, his mother was revelated, and she said, "I like you to repay Kong Beihai."

Repay what kind of kindness is to be done.

Liu Bei remembered the incident of Banyan, so he told several coaches.

Shanman Qu Shuai smiled and said: What's the difficulty? It's just a solid wooden board. When charging into battle, he raises a shield in front of him and advances like a wall. He just blocks the soldiers' bows, arrows, swords and guns.

Liu Bei asked again: Can a clan form a squad?

Zhongqusang nodded happily: Now!

The Banyan Barbarian Banyan is made of hard wood. The outer Mongolian animal skin is painted and painted. It is as colorful as a ghost, so the Qiang people are afraid of it. It is called the "Divine Weapon". It is also called "the generation of people who are born in the world, and do not travel south again."

The copper and iron shield is too heavy. The wooden shield is covered with leather and painted, which is strong enough. During the Warring States Period, double-arc square shields suitable for melee battles were prevalent. The longitudinal axis raised is conducive to decomposing the power of the spikes. During wartime, you can use a belt to tie the shield to your arm or hold its handle. It is also hung behind the back when marching.

The large shield of the squid has been improved. There is a cross-shaped corner support (stent pole) behind the shield. There are handles on both sides of the corner support. Usually, the corner support is held in the groove. When moving, the shield is raised with both hands. After stopping, the corner support can be pulled out, pressed against the ground, and arranged into a shield wall.

This setting is good, but Shaojunhou has improved.

Since you can crucify the corner support, why not replace the corner support with a crossbow?

The crossbow handle is lengthened to serve as a corner support. In wartime, you can walk with both hands on the crossbow. When standing, you can support the ground with the crossbow handle. Isn’t it a good attack and defense?

Yes!

Returning from Du Kang City, Liu Bei then went to the Jiangzhuan and told Xia Fu and Su Bo what he thought was.

After listening to Liu Bei's statement, Xia Fu nodded slightly and asked back: "Young Master, can you tell me that the 'shot and launch the crossbow'."

Liu Bei naturally knew about the concurrent crossbow, but this was the first time he heard of the "concurrent crossbow". However, it is not difficult to understand from the literal form. The concurrent crossbow refers to shooting two arrows at a time. The continuous shooting... Can it be continuously fired?!

Xia Fu took out a long-standing scroll and slowly opened it.

Liu Bei saw the ancient version of the pistol in a trance!

"This crossbow was already available during the Spring and Autumn Period and the Warring States Period." As he said that, Xia Fu took out the real object from his sleeve.

I saw this continuous-firing crossbow, which was painted black lacquered, one foot and two inches long (27.8 cm), two inches wide and three minutes (5.4 cm), and seven and a half inches high (17.2 cm). It is not large in size and is suitable for handheld. The whole body can be divided into two parts: the arrow box and the body. The body also includes four parts: the crossbow arm, the movable wooden arm, the arrow box, the crossbow bow, and the special crossbow arrow. The arrow box on the right side of the continuous-firing crossbow arrow box is stored in the arrow box, the arrow box and the arrow box on the left side, and one in the horizontal groove, a total of twenty crossbow arrows.

The bow string is made of ribs, and a small chord rod is tied in the middle of the string. When the crossbow arrow is inserted from the inlet, it will fall into the horizontal groove of the arrow box by itself. Just tilt the hand of the crossbow to the left or right, and the crossbow arrow will roll into the left and right gutters. The left and right gutters can be equipped with up to twenty crossbow arrows, ten in each groove. After installation, the two bottoms fall on the left and right launch surfaces to press the gutter.

The entire process of continuous firing and slow firing includes three stages: string pulling, firing, and hooking.

When firing, pull the movable wooden arm backward, and the tooth in front of the movable wooden arm hooks the chord and runs backward. When the chord runs to the tail end of the crossbow arrow, the crossbow arrow will break off the chord and land on the launch surface. The movable wooden arm continues to run. When the tail end of the hanging knife touches the starter copper bolt, the tail end is lifted, and the coracoid process at the front end will leave the concave of the machine teeth and sink to the bottom. Under the action of the tension of the chord, the chord falls forward, and the chord breaks out from the tooth mouth. The elastic force of the chord moves forward quickly, driving the two crossbow arrows on the launch surface to shoot out and complete the launch.

After shooting, the chord runs to the front end of the crossbow arm and is pressed by the two crossbow arrows falling from the veil storage box. At this time, push the movable wooden arm forward. When the prop behind the machine teeth touches the chord, the collision causes the tooth mouth to rise and the front support to hook the chord. At the same time, the front end of the hanging knife takes off the bottom, pressing against the concave of the bottom, and the rear end automatically falls into the machine groove, and everything returns to the state before launch.

The entire launch process may be complicated, but the actual operation is only a pull and push, which is very simple.

If the crossbow arm is used as a metaphor for modern rifles, it is equivalent to the gun rod and the buttstock. Its shape is long, with a concave front end, and a support projection that supports the crossbow bow extends from the lower part, and a curved handle is placed at the bottom. The rear section is chiseled through holes, which are equipped with a copper pivot. The upper plane of the crossbow arm is slightly higher, and there are two semicircular launch holes at the front end. A rectangular groove with a rear end opening is chiseled in the middle of the upper plane, and the movable wooden arm (or machine profile) is installed in the groove. The left and right sides of the groove are smooth, which is the launch surface of the crossbow arrow.

The movable wooden arm is flat, made of hardwood, with the front end chiseling through the bottom machine groove, and copper hanging knife and machine teeth are installed in the groove. The shape of this movable teeth is obviously different from the tooth of an ordinary crossbow. It looks like a bird's head. The two protruding protruding front and back are like open bird beaks, short in front and long in the back, and there is a concave at the bottom of the movable teeth. The movable knife is like a broken chime. The movable teeth are in front and the hanger is at the back, and are fixed at the front end of the movable wooden arm by a copper pivot. The movable wooden arm is installed in the groove of the crossbow arm, which is the key to firing and its function is equivalent to the firing device of a modern rifle.

The veil storage box is installed above the crossbow arm, which is equivalent to the bullet casing and gun barrel of a modern rifle. It is rectangular, with a square end folded at the front, and there are two semicircular holes at the bottom. These two holes are closely linked to the semicircular holes on the crossbow arm to form a circular hole, which is set for launching the crossbow arrow. The rear section is engraved as a tiger's head shape, and a rectangular veil hole is opened in the middle of the tiger's forehead. A rectangular horizontal horizontal groove is set at the upper part of the box, and the rear end of the groove is connected to the veil hole. Below the horizontal groove, there are two deeper vertical grooves on the left and right sides, for the purpose of veil storage. In the middle of the bottom of the veil storage box, there is also a longitudinal machine groove extending into the tiger's head at the rear end. When the veil storage box is installed with the crossbow arm, this groove allows the movable wooden arm to move forward and backward.

The crossbow is very small, only three inches (7 cm) long, and is also made of hardwood. The inner arc is closely linked to the arch of the crossbow arm, and there is a small round hole at each end for the purpose of tying the bow string.

Crossbow arrows have copper heads and iron tails. Iron tail jackets with bamboo squids and inlaid tail feathers. The length is only six inches and two centimeters (14.3 cm), which is much shorter than commonly used crossbow arrows. It is specially made for continuous crossbows.

Because it is small in size and has a short range, it can only be used as a self-defense weapon and is not suitable for military combat. However, if the body is increased, the movable wooden arm is improved, and then the powerful bowstring is replaced, it can be used as a long-range magic weapon!

The crossbow soldiers were formed into a Banyan, and the generals were prepared for attack and defense.

Zhuge Kongming once created a profit and loss crossbow. It must be the re-creation of the Mohist "shot and fire crossbow".
