Last night, Gao Pet went to the second uncle's house to take the so-called ancestral secret book, but the second uncle was drunk and unconscious, and the aunt gave a cloth bag to Gao Pet, saying that it was ordered to him by the second uncle. In the bag, there is a hand-copied "Tao Te Ching", a "Huangting Neijing Jade Jing Annotation", a "Gao Family Shooting", a copper plate and annotations engraved with human acupuncture points on both sides, and a very popular name "Taiqing Mixed Yuan One Qi Decision", according to Gao Siji's commentary, he got from a Taoist master, and thus practiced the name of a generation of gun kings, and the king of Kaiping also practiced his strength, so he was invincible. It seems that the real strength of this inner family is indeed something. These books are all made of parchment, written in cinnabar, and the small characters on the rope head are very beautiful.

In the evening, Gao Pet mainly studied "Taiqing Mixed Yuan One Qi Decision", and went to the courtyard to play Yang's Tai Chi several times, and experienced the operation of straight qi in the body. The training and use of internal strength is very different from the training of modern sports strength, which is completely different, and pays more attention to the training of spirit and spirit and the training of illusions. Internal energy cannot be controlled by explicit thinking, but must be controlled by divine thoughts or divine consciousness, which is what is called the subconscious in modern times. It is very difficult to train this divine consciousness, and it is very similar to the cultivation of "Zen, Concentration, and Wisdom" in Buddhism. One night of research, Gao Pet somewhat understood that the internal strength should be based on the spiritual training and hypothetical training of Jinggong, and the internal strength itself does not have much strength, but it can realize the control and protection of the muscles of the whole body as the main function, and the reaction speed is very fast, faster than the human nerve reaction, and the internal true qi can also be used to regulate the physical state. Gao Zhong also understands that the control of this divine consciousness is not an easy task, and time and opportunity are the biggest key. This is in no hurry. In this era of cold weapons, the value of personal force is still a very critical indicator, Gao Pet attaches great importance to it, this internal strength cultivation must be done, and it is also the personality of an intellectual like Gu Tian, a very fascinating thing in modern times, which confirms the existence and possibility of realization, Gao Pet is like a child, very excited. For this reason, we have preliminarily sorted out an idea for future training and cultivation. This night, Gao Pet hastily slept for less than an hour, and it was time for morning exercise. When he arrived at the martial arts training hall, he knew that the second uncle didn't have any experience worth referring to, so Gao Zhong went according to the plan by himself, which made people stand up very strangely, and his mind was too wandering, as if he was sleeping. A morning workout and nothing else was done.

After breakfast, we arrived at the west courtyard, where Fauber was waiting in front of the door, and a wheelbarrow was placed in front of him. Last night, Fu Bo and his son made a big joke when they had dinner, because during the day, Gao Zhong gave a can of wine, and wanted to taste what wine the eldest young master gave during the meal. I tasted a spicy and mellow taste, but Fu Bo is almost fifty years old, I have seen this kind of good thing, the father and son each have a glass, and they will drink it all after a while, this is nearly two catties of high wine, and the amount of alcohol between the two is average, and after drinking, one cries and laughs, and then he gets drunk. The second uncle slept when he was drunk, but this father and son were special, crying and laughing. Gu Tian is a professional manager in modern times, and he has seen scenes of drinking, and there are all kinds of things, but the drunkenness of a calm person like Fu Bo is very exaggerated.

When Fu Bo saw Gao Pet coming, and saw Gao Pet smiling at him, his face, which was still green, turned red, and he spoke with a smell of wine:

"Thank you for the good wine given by the young master, I didn't know the strength of this wine yesterday, and I made a joke. This car is the wheelbarrow that the shipyard has renovated, and the factory asked me to send it over to the eldest young master to see if there is anything that needs to be improved. In addition, the young master asked the things to be done and sent them to the yard. ”

Gao Pet nodded, pulled up the unicycle and walked around, overall good, the axle was a little loud, no lubricating oil, and a small wooden box was added in front of the handlebar to put tools and items. Listening to Fu Bo's introduction, this was suggested by Master Zhang, who was trying the boat, and Gao Zhong didn't paint it at the time, but they made it, and the ancient people were actually very smart.

Fu Bo turned around and gave Master Zhang five yuan of money, saying that this was a reward for an invention and improvement, and that in the future, the shipyard would reward anyone who invented new things, new processes, and new technologies. In addition, for this car, you have people use hemp silk to weave two rings, soak them in oil, and install them on both sides of the axle, which can save effort, reduce wear and tear, and make the sound much smaller. Add a few ropes to the side, which can be used to fix things when pulling, and then weave a braided belt, not a strap made of round rope, so that the shoulder will not hurt when the time comes. ”

In the yard, the second uncle is directing the big pillar to classify and stack the things and materials that were originally made, and the scene that was more chaotic yesterday has been cleaned up, because of the confidentiality relationship, only these few people, of course, the big pillar is the main laborer, the second uncle himself is also himself, the two younger brothers do some small things, but they are all very interested, except for the big pillar, all of them are sons, do these rough work? Hehe, Gao Chongyin smiled, Mao said, "morality, intelligence, and physical development should be all-round", and it is necessary for them to carry out proper labor training.

Because of the threading and drilling, Gao Zhong first assembled the most primitive manual lathe. This is the first mother machine in the modern machinery industry. Although most of them are made of wood, they are still manual, and the accuracy is very poor, but this is the basis of all precision machining.

Seeing Gao Pet loading things, a few people stopped doing anything, and came around to watch, the little brother Gao Fan asked questions and asked questions, and looked like a studious baby. Seeing the second uncle's curious and inquiring eyes, Gao Zhong explained:

"This is a lathe that is used to machine round parts and drill holes."

Gao Pet clamped the parts blank on the lathe, and let the big column shake the handle behind it to make the lathe spin. Due to the limited strength of the big column, Gao Pet adjusted the amount of cutting of the lathe to the minimum, and a set of screws made it for a long time, and there was no power, so he had to use this kind of water grinding effort.

The processed parts are good, Gao Pet installed the first hand crossbow, let them put the other hand crossbows well, although the gourd is still drawn, but also often make mistakes, especially on the pulley to install tension, repeated several times to get it, several people, Gao Yang is the fastest, but the second uncle is the slowest.

These five crossbow bows, there are three specifications, because of the relationship between the material and process of the bow piece, Gao Pet does not know the elasticity and strength, the preliminary design is 4 stone, 3 stone and 2 stone bows, but the specific how to go through the test to know the performance parameters of the entire bow.

This bow is very different from the rhubarb crossbow used in the Southern Song Dynasty. First, a crosshair and ruler are installed to ensure the accuracy of shooting. The second is that the string adopts the labor-saving device of the pulley group, and the third is that the string is not grabbed by hand, but the string puller made of the lever labor-saving principle, the design of the plate machine can avoid the vibration of the string to ensure the stability of the firing, and there is a grip that conforms to the man-machine function, and the foot ring is specially made, which is different from the rhubarb crossbow with both feet on the bow. The string is fast and labor-saving, and the speed of the arrow is fast. Shooting is smooth, accurate and controllable. Soldiers are trained for a short time.

Load the crossbow and adjust the tension of the bowstring. Then everyone worked together to make arrowheads, shafts, and tail wings into crossbow arrows. In order to unify the system, only two specifications of arrows are equipped, one is a standard arrow, about one foot long, with two balanced tails, weighing about 20 grams, of which, the steel arrow weighs about 9 grams, and a short pole arrow is about 6 inches long, each weighing about 15 grams, and each has a hundred pieces. This batch of crossbow arrows, using steel core armor-piercing triangular arrows, reduces the resistance during movement, the shaft of the arrow is made of lightweight cork, the straight warp is about three points, oiled and moisture-proof, the long pole arrow is equipped with two balanced tails to ensure the balance of flight, and the short-rod arrows have no tail. Due to the difference in weight, the muzzle velocity of the long and short rods is different, and therefore, the range is also different.

After everything is ready, put the crossbow and arrows into a box, let people carry them, everyone went to the shooting range, the second uncle emptied the people on the field, set up the arrow target at different distances, and Gao Pet began to adjust the arrows, there are two main adjustments, one is that the sights and rulers should match the arrow path, and the other is that the tension of the string should be adjusted to the appropriate and marked, so that it can be used in one step.

The three long arrows can be projected at an effective distance of 225 steps, 360 steps, and 560 steps, while the short arrows can reach 300 steps, 500 steps, and 750 steps respectively, preparing for the unified system. However, the direct aiming distance, because the maximum design of the mountain is about 10 degrees, so the effective range of course has to be greatly discounted, the effective distance of the long arrow is 85 steps, 140 steps, and 200 steps respectively, and the short arrow can reach 110 steps, 180 steps, and 260 steps respectively.

Long pole arrows have a higher shooting accuracy while short poles shoot farther. Short-game arrows are better suited for projectiles.

Thanks to the steel core, it can penetrate an inch-thick hardwood board within the effective range of direct aiming. The power is pretty good

The upper chord of the three kinds of bows can save four-fifths of the force due to the pulley group and lever structure used in the upper chord, and the force required is about 48 catties to 96 catties, which can be done by ordinary people. Due to the low effort and more advanced aiming mechanism, the rate of fire is much higher than that of traditional crossbow arrows. Gao spoiled a lot of time to adjust the crosshairs, rulers, and tick marks. This debugging was time-consuming, and it was not completed until the afternoon of the next day.

The second uncle's archery level is very high, so he is the main force when adjusting.

The younger brother, who had never shot an arrow, quickly mastered the method of aiming after trying two or three arrows, followed by Arrow Heart, who seemed to have the potential to be a sniper. Even the eldest brother and the big pillar are not as good as him. Maybe Yang Fan changed his habit of hating martial arts, and it is unknown.

"Second uncle, do you want to compare the rate of fire and durability with the bow and arrow?" Gao Pet said deliberately. In fact, in the process of debugging, the second uncle already knew the bottom of various parameters.

"No, if you consider that the rate of fire is about the same, but an archer shoots five or six arrows in a row is quite good, and if you can shoot more than ten arrows in a row, you are a master, and there is so much human strength. But the accuracy rate cannot be compared with this, it is so simple to wear Yang in 100 steps, only one less genius has to practice for more than ten years to do it, and it takes 1 out of 10,000 miles. You said that our Xiao Fan Ke is a super archery genius, and he has only been in contact with archery for a while, and he is better than us. This sight is good. "The second uncle's words, the little alum went back to the mother, but it had to be blown.

"Big brother, the name of that big yellow crossbow is so popular, what is the name of our such powerful crossbow and crossbow arrows" Gao Alum was just encouraged and thought about how to brag to others when the time came. The desire to be recognized is very high. Gao Pet slapped Xiao Alum on the head and said:

"You haven't chosen a name yet, Xiaofan, don't keep thinking about bragging, and forget all the discipline that was set before?"

"I didn't, that's all I said." Xiao Fan argued.

"Darling, our crossbow and arrow really have to have a resounding name, and let people know that the products produced by the Gao family must be high-quality." The second uncle is not simple, and there is brand awareness.

"It's called the ox fork crossbow, our crossbow shoots far, shoots fast, shoots accurately, more ox forks, the name of the cow fork is the best" Gao Alum was very excited, and there was a reason, I heard that they should be named screaming.

"It's called the exterminating crossbow, we can shoot so far with a small amount of strength, so we add a few wheels, which is very mysterious, and it shoots like a divine help." Gao Yang also used his little brain, but the name is very good.

"Well, the exterminator, interesting," the second uncle spoke.

"Since the second uncle thinks it's good, let's call this crossbow the exterminating crossbow, and this arrow is called an armor-piercing arrow." The steel core of the arrow is the key to armor piercing.

"That's it." The second uncle finally made a decision
