Xuanmen Xiaoguo Shi is divination again

Chapter 821
Hey, forget it, what does he care about with this little radish, he has such a little thing, and he doesn't understand how terrible the question that Sister Mu just asked is.

The young man who knew he couldn't understand Li Yunchi, and couldn't take his anger seriously, sighed, and then, as if resigned to his fate, he took the nasty little dough ball and hurried to catch up with Mu Xiyin and the others.

When they arrived at the martial arts arena in the Duke's Mansion, Mu Xiuning and Mo Qingyun had just exchanged martial arts, and they were chatting and resting by the weapon rack.

Following the sound of everyone's footsteps, the two of them turned their heads and couldn't help raising their eyebrows slightly. The moment Mu Xiuning saw the firearm Mu Xiyin was holding in his arms, he rushed forward with a bluff.

"Hey, you guys are so majestic!" The red-clothed boy laughed and raised his long eyebrows. He leaned forward and stretched his head while talking, his eyes were fixed on the firearm. What is this holding?"

"The flintlock gun that was drawn a few years ago," Mu Xiyin said lightly with half-closed eyebrows, "I entrusted this blueprint together with the blueprints of the god arm crossbow and the bed crossbow to the Seventh Highness. I don't want the blacksmiths on His Highness' side to be so powerful, they can make this thing so quickly."

"I originally thought that it would take another year and a half to show up... It's useless not to mention these things, Aning, how many archery and crossbow targets are there in our Duke's mansion? I want to try Try the effect of this gun."

"Well... there are about ten straw targets and twenty wooden targets," Mu Xiuning rubbed his chin and pondered for a while, "In addition, a new batch of human-shaped wooden targets arrived in the mansion yesterday—sister, what do you need? Which kind?"

"Let's move five sets of the same one first. If it's not enough, then send someone to get it." Mu Xiyin ordered in a low voice, and then added bullets to the firearm by herself, "Aci, you Come get a basin of water by the way."

"Understood." Upon hearing this, Master Mu nodded quickly, but Mu Xiuning raised his hand and scratched his head for no reason when he saw this.

He stood on the spot and thought for a while, seeing that he still couldn't figure out what his sister was thinking, he simply shrugged his shoulders, grabbed Mo Junli with one hand, and grabbed Mo Qing who was about to cling to his sister with the other hand Yun, dragging the two of them involuntarily, turned straight to the warehouse of the Martial Art Field: "Let's go, brother-in-law, Your Highness, the three of us will carry the target for Sister and the others~"

The movements of these three people have always been neat, and they rushed back carrying all kinds of targets that Mu Xiyin needed, and Mu Xici also prepared the basin of clear water that Mu Xiyin needed: "Sister, what do you want?" Everything is ready."

"Okay." Mu Xiyin carried the firearm weighing more than ten catties, walked to the end of one side of the martial arts arena expressionlessly, and raised her jaw slightly forward, "A Ning, dispose of a firearm at fifty feet. Put a wooden target, and then place a grass target about four feet behind the wooden target, and adjust the two targets to the same height."

"That's it!" Young Master Mu nodded in response, and quickly found a place with the two targets in hand. Seeing that the two targets had already been set up, everyone hurriedly stepped aside. Mu Xici looked at the one standing behind the wooden target. The straw target four feet away couldn't help frowning deeply.

——When marching and fighting, the distance between the soldiers in the ranks is about two to four feet.

If it is too close, it is easy to be unable to walk, and the soldiers are easy to accidentally injure their comrades with the weapons in their hands and the bags on their backs.

If the team is too far away, it is easy to be dragged too long. If the weather is windy, sandy, rainy, snowy and foggy, it is very easy for people to get separated and fall behind.

In addition, the body length of the current horses in the Qianping Army (I checked the average data of various ancient horses, and note that most ancient horses are not as tall as modern horses) are mostly between four and five feet...

Therefore, when the soldiers marched, most of them would deliberately control the distance within two to four feet.

If the lead|zier still has enough power to drive into the grass target after piercing through the thick wooden target, it means that this new firearm has a great probability that it will enable them to attack the target while the enemy is marching on the road. One shot pierced both of them.

hiss~
The little girl gritted her teeth and gasped softly, then stared nervously at the two targets.

Mu Xiyin finally checked the firearm in her hand, made sure everything was normal, aimed at the bullseye and pulled the trigger.

Everyone only heard a loud "bang" sound behind their ears, and a hole was dug out in the inch-thick wooden board fifty feet away.

"A Ning, take a look, has the gun pierced through it?" Mu Xiyin held the firearm upside down, and raised her hand to rub her shoulders and sore arms that were numb from the huge force.

Although her health has improved a lot in the past few years, she is no match for those who practice martial arts all the year round.

This blow, although it didn't exhaust her strength, it did make half of her body numb for a moment.

The shock absorption is not enough, the momentum of this thing is much greater than she imagined, ordinary people may not be able to play with it without training, and her body still lacks some exercise.

——Tomorrow, I will follow Ah Yun and the others to get up early and go to morning exercises.

Mu Xiyin lowered her head and muttered, but after looking at the target, Mu Xiuning broke out in a cold sweat uncontrollably.

"Punch... pierced, sister, pierced, and hit the bull's-eye!" The boy in red opened his throat in excitement, and his eyes flashed with a strange brilliance that he couldn't tell whether it was joy or fear.

He had also seen the soldiers in the Shenji Battalion use firecrackers before (refer to ancient firecrackers), but that thing was clumsy and heavy, and it took two people to use it clearly, and the accuracy was not ordinary.

Such a two-foot-square wooden target, if it is replaced by the firecracker, let alone hit the target, with such a distance, it is not bad to be able to hit the inner third circle of the target board.

As a result, the firecracker modified by my sister not only hit the bull's-eye, but also pierced the target, even, even...

Mu Xiuning touched the hole and looked back subconsciously, but his eyes suddenly froze the moment he touched the straw target, his eyes widened in disbelief, his mouth froze for a moment, unable to speak.

"Then what about the straw target at the back? Is the straw target worn?" The woman whose arm was recovering from fatigue slowly moved her wrist, and casually asked the second question.

It was within her expectation that the firearm could penetrate the target, and she was more concerned about whether the grass target could penetrate it or not.

"Wear it, put it on." Mu Xiuning stammered and forced out a sentence, but the few simple words made his mouth so dry that he almost lost his voice, "The straw target... the straw target is also worn. "

"Sister, the bullet went through the grass target and still flew a long way, and it will land more than a hundred feet behind the grass target!"

"Okay." Mu Xiyin nodded, and raised her eyebrows a moment later to command Mu Xiuning.

"Ah Ning, move these two targets fifty feet back and place them at a hundred feet away."

(Note: The above data are all estimated by the author. It is found that the upper limit of the ancient flint||hair|| gun is about 500-600j, the muzzle velocity is about 350m/s, and it takes about 25j to wear a 78mm red pine board. My sister’s gun is weak In the later stage, the grass target is ideally equal to the wooden target. The thickness of the wooden target is 33mm, and the height of the bullseye is about 1.5m. The taken is about 300m/s and 400j. The air resistance and wind resistance are estimated, g=9.8, and the trajectory is fitted Three-segment parabola, the manual estimation error is large, but the separation spectrum is fine, just look at it)

　I wrote the first [-] characters very happily, but after writing the grass target, I suddenly felt that the data was wrong.

　　Then I started frantically looking for data to check kinetic energy.

　　It’s just a matter of fucking simulating the quality of the projectile used by my sister ==
　　Fortunately, the almighty Du Niang let me find the kinetic energy of the flint|hair|gun in the corner and saved my dog's life.

　　However, this calculation is still very numb, because the wind resistance and air resistance of the day are unknown, and it is not clear whether there will be additional loss after wearing the board, so the estimation based on the data pulled to the extreme value is definitely not accurate, just make do with it.

　　In a purely ideal state, after wearing a 66mm wooden board, you can still fly about 90m, but I lost more than half of it cruelly. After all, when wearing the second board, the initial speed is already diagonally downward.

　　I never thought that writing essays would one day return to the embrace of big physics problems. I have graduated for many years! !
