Zhou Tai's case is not an isolated case.

In the fourth year of the first peace, Beihai Xiangkong Rong heard about Tai Shi Ci's old affairs, and was very surprised, so he sent people to ask Tai Shi Ci's mother several times, and gave gifts to pay his respects.

The yellow scarf besieged the city, and the loving mother sent Tai Shi Ci to help.

After the event, he also enlightened his mother, and his mother said: "I am happy that you have to repay Kong Beihai." ”

Kindness will be repaid, and righteousness will be desired.

Liu Bei remembered the matter of Ban Yuman, so he told several Qu Shuai.

Shan Manqu Shuai smiled: What's so difficult about this. It's just a solid plank. When charging into battle, raise the shield in front of you, like a wall. Shielding the soldiers from bows, arrows, knives and guns.

Liu Bei asked again: Can the clan form a plate soldier?

Zhong Qu Shuai nodded happily: Huh!

The slabs are made of solid wood. Covered with animal skin, painted with lacquer. Colorful as a ghost, so the Qiang people are afraid. It's called 'Divine Soldiers'. And "pass on the language generation, don't go south".

The brass and iron shield is too heavy. The wooden shield is covered with lacquer and is strong enough. During the Warring States period, double-arc square shields suitable for melee combat prevailed. The longitudinal axis is convex, which facilitates the decomposition of the force of the spines. In wartime, the shield can be worn around the arm with a belt or held on the handle. It also hangs behind its back when marching.

The big shield of the plate is improved again. Behind the shield there is a cross-shaped corner brace (pole). There are handles nailed to the left and right sides of the corner brace. Usually the corner is closed in the slot. Raise your shield in both hands as you march. After stopping, you can pull out the corner brace, press against the ground, and line up to form a shield wall.

That's a good setting. However, the young prince and marquis have improved.

Since it can be crucified. Why not replace the corner brace with a crossbow?

The crossbow handle is lengthened to serve as a corner support. In wartime, you can walk with a crossbow in both hands. Stand on the ground with a crossbow handle. Isn't it both offensive and defensive!

Yes!

After returning from Dukang City, Liu Bei went to the Jiangzuo Pavilion and talked about his thoughts with Xia Fu and Su Bo.

After listening to Liu Bei's statement, Xia Fu nodded lightly and asked rhetorically: "Can the young master know 'parallel fire repeating crossbows'." ”

Liu Bei naturally knew about the concurrent repeating crossbow, but this 'parallel firing continuous crossbow' was the first time he had heard of it. But it's not hard to understand. Parallel shooting refers to shooting two arrows at once. Bursts...... Can it be launched continuously?!

Xia Fu took out an old picture scroll. Slowly open.

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

"This crossbow was already available in the Spring and Autumn Period and the Warring States Period." As he spoke, Xia Fu took out the real thing from his sleeve again.

I saw that this part-time fire repeating crossbow was black and lacquered, one foot two inches (27.8 cm) long, two inches and three minutes wide (5.4 cm), and seven and a half inches (17.2 cm) high. It's not big, and it's perfect for hand-holding. The whole can be divided into two parts: the arrow box and the body. The body includes four parts: crossbow arm, movable wooden arm, arrow storage box, crossbow bow, and special crossbow arrows. There are 10 arrows in the right slot of the repeating crossbow box, 9 arrows in the left slot, and one in the horizontal slot, for a total of 20 crossbow arrows.

The bowstring is made of ribs, with a small chord tied to the middle of the string. When the bolt is loaded from the inlet of the arrow, it will land in the horizontal slot of the receiver. Simply tilt the hand holding the crossbow to the left or right, and the bolt will roll into the left and right reservoir slots. The left and right storage slots can hold up to twenty crossbow arrows, ten in each slot. After installation, the bottom two fall right on the left and right launch surfaces, pressing down on the chords.

The whole process of parallel firing and continuous firing includes three stages: string pulling, launching, and hooking.

When firing, pull the movable wooden arm back, and the teeth in front of the movable wooden arm hook the chord and run backwards. When the chord reaches the tail of the crossbow, the bolt disengages from the chord and lands on the launch surface. The movable wooden arm continues to run, and when the tail end of the suspension knife touches the starting copper bolt, the tail end is lifted, and the coracoid process at the front end will leave the recess of the machine tooth and sink to the bottom of the tooth. Under the action of the chord pull, the machine teeth fall forward, the chord comes out of the tooth mouth, and the elastic force of the string moves forward rapidly, driving the two crossbow arrows on the surface to shoot out and complete the launch.

After firing, the chord runs to the front of the crossbow arm, where it is again held down by two bolts that fall from the receiver. At this time, the movable wooden arm is pushed forward, and when the branch behind the machine tooth touches the chord, due to the collision, the tooth mouth is upward, and the front branch hooks the chord. At the same time, the front end of the suspension knife detached from the bottom of the tooth, resisted the depression of the bottom of the tooth, and the rear end automatically fell into the machine slot, and everything returned to the state before the launch.

The whole launch process is complicated, but the actual operation is only in a pull and push, which is very simple.

A crossbow arm, to use a modern rifle analogy, is equivalent to a gun shaft and a butt. It is in the shape of an elongated strip, with a concave front end, a hook-and-hook branch that protrudes from the lower part supporting the crossbow, and a curved handle below. The rear section is drilled through the hole, and the copper pivot is installed inside. The upper plane of the crossbow arm is slightly higher in front and behind, and there are two semicircular firing holes at the front end. A rectangular groove with a rear end opening is chiseled in the middle of the upper plane, and the groove is equipped with a movable wooden arm (or machine profile), and the left and right sides of the groove are smooth, which is the firing surface of the crossbow arrow.

The movable wooden arm is in the shape of a flat strip, made of hardwood, and the front end is chiseled through the bottom of the machine groove, and the copper hanging knife and machine teeth are installed in the groove. The shape of this tooth is significantly different from that of an ordinary crossbow, resembling a bird's head, with two protrusions at the front and back shaped like open beaks, short in front and long in the back, and a concave at the bottom of the teeth. The hanging knife is shaped like a chime. The teeth are in the front, the hanging knife is in the back, and the copper pivot is fixed at the front end of the movable wooden arm. The movable wooden arm is mounted in the slot of the crossbow arm, which is the key to firing, and is equivalent to the firing mechanism of modern rifles.

The magazine is mounted above the crossbow arm and is equivalent to the magazine and barrel of a modern rifle. Rectangular box-shaped, the front end is squarely folded, and there are two semicircular holes in the lower part, which are closely fastened into a round hole with the semicircular hole that matches the crossbow arm, which is set up for firing crossbow arrows. The back section is carved in the shape of a tiger's head, and there is a rectangular arrow hole in the middle of the tiger's forehead. The upper part of the box is provided with a rectangular horizontal horizontal groove, and the rear end of the groove is connected to the sagittal hole. Below the transverse groove, there are two deep vertical grooves on the left and right sides, which are used for storing arrows. In the middle of the bottom of the storage box, there is also a longitudinal slot that extends under the rear tiger's head. When the receiver and crossbow arm are installed together, this groove is used for the movable wooden arm to move back and forth.

The crossbow is small, only three inches (7 cm) long, and is also made of hardwood. The inner arc is just closely integrated with the crossbow arm bearing bow, and there is a small round hole at each end for wearing the bowstring.

Crossbow bolts with copper heads and iron tails. The iron tail coat is made of bamboo and has inlaid tail feathers. At only six inches and two minutes (14.3 cm) long, it is much shorter than the usual crossbow arrows, and is specially designed for repeating crossbows.

Because of its small size and short range, it can only be used as a self-defense weapon, and is not suitable for military combat. However, if you increase your size, improve your movable wooden arms, and equip a powerful bowstring, you can become a long-range shooter!

Organized into a crossbow soldier with a board and a company, it will be ready for both attack and defense.

Zhuge Kongming once made a profit and loss crossbow. Presumably it is a re-creation of the Mo family's 'parallel fire repeating crossbow'.

Liu Bei ordered Xia Fu and others to try to build a plate crossbow.
