Manchu civil and military bow down

The reason was that Gu Xihuan shot a wild goose and was about to shoot it down.But when the bow was drawn too weakly, the arrow hit the goose's body and bounced back.He became a fat ball in anger, threw his bows on the ground, and shouted, "I want to change my bow! This bow is not suitable for me!"

Xu He stood not far from him and rolled his eyes.

What bow is right for you?Just like you, only children's slingshots are suitable.

He stretched out his arms to draw the bow and let go of the arrow.

call out--

The arrow flew straight.

But this time, Xu He was like Gu Xihuan, because of lack of strength, the arrow barely brushed past the fur of a wild goose.

Missed.

Not strong enough?

Xu He looked ahead, thoughtful.

The sound of arrows piercing the air came from afar.

Xu He turned his head to the side, and it was the arrow shot by Bu Jinglan, which was as fast as the wind, and pierced the throat of the wild goose in an instant.

The wild goose wailed and fell to the ground.

The archer's expression was cold and boring.

popping.

"Good!" The master who taught archery came slowly, applauded, and looked at Bu Jinglan with admiration: "Very good. "

The disgust on Bu Jinglan's face was fleeting, as fast as Xu He's illusion, and replaced with a shy smile, restrained and gentle, "Teacher is too praised."

Being strong and docile, the instructor admired Bu Jinglan more and more, and told everyone about his actions as a standard again.

Before leaving get out of class, I explained some things.

Xu He didn't listen the whole time, and only vaguely caught the last bit of information. Five days later, everyone in the National Academy will hold a hunt in the forest of the imperial palace, which can be regarded as a quiz.

But he didn't care much about this, a word that was turning around in his mind... Tension.

After returning, he sat in front of his small desk and looked up a lot of information in his brain with the golden finger given by the system.

His idea is to borrow elastic force to make a hidden weapon with great tension, long range and strong damage.

Xu He picked up a self-made charcoal pencil, borrowed from the famous hidden weapons in ancient times, such as "blood droplet", "sleeve arrow", "blowgun" and so on, and drew while rubbing on the paper, intermittently, drawing A square diagram of the mechanism was drawn up.

He lowered his eyes, just below the painting, calculating the data.

He filled a sheet of paper, first calculated the length of the spring that can be gathered when the capacity of the wooden block is used to the maximum, and then estimated the friction force and other data to obtain the final tension that can be achieved.

He was a little taken aback when he figured out the answer.

Four hundred times? ?

The range is about 500 meters.

Damn, Xu He propped his chin and tapped with a pen: "If you put some poison on the needle, it will be a sharp weapon for killing people."

He looked up and glanced out the window, the sky was foggy, and it was already the dawn of the second day.Xu He didn't sleep all night, but Xu He was very excited.He didn't need to change his clothes anymore. He went out early in the morning and found a lot of smooth wooden blocks. He carried them in his arms, took a small knife, and slowly carved and polished them, finishing the small parts one by one.

For the force transmission part in the middle, he needs to use iron. For this reason, after class, he found Jiancheng and begged him to send someone to find him some iron pieces from the blacksmith outside the imperial city. .

Originally, Jiancheng didn't agree to it even if he died, so he told him not to mess around with the children.Xu He had no choice but to use his unique rights at this age to act coquettishly and shamelessly to persuade Jiancheng.

Jian Cheng's face darkened: "...Okay, I agree."

Xu He couldn't close his mouth with a smile: "Thank you."

On the way back, he took his sketches and pored over them to see if there was anything that needed to be revised.

Passing the promenade of the academy, the green vines are entwined, and the light and shadow are disillusioned.

He raised the picture in his hand, faced the sun, squinted his eyes, and said, "I'm such a genius."

To Xue Chengyu, Xu He was so well-behaved these two days that he seemed like a different person.

But cleverness is cleverness, but people are still stupid.Holding a pile of wood, holding a small knife, lowering his head and lowering his eyes, he was sharpening it there.The sawdust flew to the nose, but I didn't notice it.

Even when I was eating, I felt as if I was possessed. I scratched the table with my chopsticks and wrote strings of ghostly symbols.

Xue Chengyu's hand holding the chopsticks paused slightly, and there was some doubt in his cold eyes, but he still chose not to disturb.

Put down the chopsticks and watch quietly.

The light outside the window cast a shadow on the boy's fair side face.

The eyelashes are very long, and the lips are as red as if dyed with flower juice.

Xue Chengyu thought casually, he is still cuter when he is quiet.

"call!"

The moon and stars are thin outside the window, and the oil lamps in the room are like beans.After three days and three nights, Xu He finally got his little box out.While letting out a long sigh of relief, a great sense of accomplishment and pride welled up spontaneously.He jumped up from the stool, without shoes on, opened the door and went to find Xue Chengyu.I just want to share this joy with my friends.Yes, now he unilaterally thinks that Xue Chengyu is his best buddy.

"Xue Chengyu, Xue Chengyu—" Excited, Brother Xue didn't even want to shout.

Xue Chengyu pushed open the door, and the first thing he saw was Xu He's bare feet. His ankles were very thin, and his skin was almost transparent under the moonlight.

He froze for a moment, quickly moved his eyes away, and looked at the young man who was full of joy, as if he had been planted by a star.

Holding his wooden box, Xu He tried his best to suppress his pride and joy, but the smile on his lips still couldn't hide: "I succeeded!"

This kind of smile is too contagious.Joy is overwhelming, floating in every inch of air.

Xue Chengyu paused, and said, "Yes." Congratulations.

Xu He was so complacent that he almost had "I'm a genius" engraved on his forehead, and he looked at Xue Chengyu eagerly.

Xue Chengyu's mind is extremely clear, and he is as good as he is: "What did you do?"

Although he is not very curious.

Xu He was overjoyed: "Murder and plotting, robbing wealth and sex must use divine weapons!"

"..."

Xue Chengyu stared at him for a long time, then smiled coldly.

Xu He noticed that the air pressure was getting low, and immediately put away that playful smile.

Pulling Xue Chengyu's sleeve, "Go, go, let's go into the room and say, I came out without shoes on, I'm about to freeze to death."

into the house.

Xu He almost regards himself as the master of this place now.He poured himself a glass of water in a happy mood, and then poured Xue Chengyu a glass of water courteously.

Xue Chengyu lowered his eyes, moved the tea cover with his slender fingers, and waited.

Xu He took a sip of tea, cleared his throat, and put the cube box on the table: "That's it, don't look at it looks like a square box, it's actually very powerful. Look here, this groove, as long as one Press it, from this side," he turned over, "from this opposite side, a needle can be shot out."

There was a sharp light flashing in the depths of Xue Chengyu's eyes, but the drooping eyelashes covered the emotional fluctuations, and he said calmly, "Continue talking."

"What are you talking about!" Xu He stood up, walked around the room barefoot, then walked to the window, and saw a row of birds perched on the eaves at a glance.

His eyes lit up, and he waved to Xue Chengyu.

Xue Chengyu didn't drink that cup of tea, got up and stood beside Xu He.

Xu He handed him the boxy box, "You shoot them."

Xue Chengyu gave him a cold look, and took it with his fingers. The moonlight shone through the sparse flowers and plants. The young man in white lifted up a wooden box, his gaze was as sharp as a knife, and the clicking sound was small but crisp.

Almost as soon as the sound sounded, a bird on the wall fell silently to the ground, while the rest of the birds were startled and flew away with flapping wings.

Xu He patted the window excitedly, "It's amazing."

Xue Chengyu's eyesight is so good that he can even see that the silver needle directly passed through the bird's body, and flew forward a long way before disappearing at the end of his sight.

The bird died in an instant, without even spilling blood.

The wind is blowing.

No surprise or praise.

"???" The silly and happy Xu He was a little dazed, his excitement slowly subsided, and Xu He looked at Xue Chengyu who looked indifferent with a little doubt.

...Why are you so serious? ?

I don't really think he was used to kill people.

Fuck it, don't.

Xu He had black lines on his face, and wanted to explain: "I didn't invent it to kill people."

"Xu He."

Xue Chengyu turned his head before he finished speaking.

When he called out, Xu He was stunned.

Xue Chengyu's brows were cold, his head was half down, his eyes were deep and distant, staring at him for a long time, Xu He thought he would say something, but in the end Xue Chengyu's eyes narrowed slightly, and he just said, "Don't let too many people know about this matter. .”

"……what???"

Xue Chengyu then said: "You are still too young."

"...???"

Xu He was still at a loss until he walked out of Xue Chengyu's room.

What the hell?

However, Xue Chengyu has been taking care of him these days. Although he doesn't understand, he is willing to listen to him.

It’s okay to play secretly by yourself, anyway, he still has a long time to make other things in the future, and this one is not bad.

Xu He left.

Xue Chengyu sat back at the table with a dignified expression. He was in a hurry, holding a brush in his hand, and based on his memory, he vaguely drew a rough figure on the rice paper.He tried to fill it in, his thoughts swirled, he tried many kinds, mental calculations and deduction, and finally settled on a basic one.

If Xu He saw it, he would be shocked. This is infinitely close to the original drawing he drew.

Xue Chengyu stared at the drawing indifferently for a long time.

Then roll it up and let the candle burn slowly.

The candlelight reflected in his eyes, the young man's eyes were dark, without any emotion.

It is not a good thing to show your sharpness too early.

What his father told him so earnestly back then, he now tells another person in a different way.
