Chapter 393: Turning Stone into Gold
The ancient swords of the Qin Dynasty are recorded in "Ancient and Modern Sword Records" written by Mr. Hua Yang.

Goujian Sword of the King of Yue is recorded in "Jueyue Shu".

There are many folk legends about these two swords, and they are all praised for their sharpness. In particular, the mysterious tempering method that makes the appearance shiny and always new, and hard to attack jade, is praised as a magical skill.

Could it be that these two swords have been tempered by that five-stone forging method?
Qingyun wants to refute, but he has no evidence.Why are these two swords so different if it is not for the use of such legendary magical methods?
If you can't continue chatting, you can only move your hands and feet.

Qingyun and Liu Ying volunteered their labor to backfill the deep smelting pit to prevent smoke and waste from polluting the surrounding environment.

Several people worked all day to restore the surroundings to their original natural appearance.

During the chat, Qingyun knew that the fuselage of the crossbow machine had been basically assembled, and two modes of use had been developed, so he pestered Yuzhi to watch the treasure.

Jizhi looked at Mr. Huayang.

The latter sneered, "Huh? Look at me. You never hide it from your friends, and it's normal for people to be curious."

Kezhi shrugged his shoulders, and sighed at his friends again, "This crossbow is the painstaking effort of the teacher and father, but that's still secondary. The main reason is that once this weapon is born, it may become a real murder weapon. It may completely It is a way to change warfare, so the master did not intend to disclose this invention."

"Is it so 6?" Qingyun, Liu Ying, and Yin Seke looked at each other and expressed their opinions one after another.

"Let's just take a look, and we won't spread it around."

"Yeah, I won't say it."

A few people glanced blankly, as if to say: I believe you ghosts!

However, because of his brother's affection, he went to the room and took out a long box.

The box is about two feet wide and four feet long, so it's really not small.

Under the stares of the three curious little ones, Tiezhi opened the box.

The box is very delicately made, and the internal parts are separated by blocking blocks.

Inside are the main body of a crossbow, a rod-like device like a long-barreled water gun, a small arrow with a base, and a small cylinder. There are also a few vacant grids that should be reserved for future placement. shoot arrows.

Except for the main body of the crossbow, neither Liu Ying nor Yin Se knew each other.

Qingyun was a little stronger than them. He knew that the small cylinder must be an aiming device, and that the small arrow was similar in structure to the weather vane in Guanxing Pavilion in Guangling, but he couldn't figure out the purpose of that water gun for a while.

"Second brother, this scope is made of plaster, right? But what's the use of these weather vanes and water guns?"

"That's not bad, I can understand the general idea." Ji Zhizhang raised his thumb to express his approval, "But this time the lens is not ground with plaster, but with Poly. The transparency and processability of Poly are very good. Much better than plaster."

Jizhi gently took out the scope and handed it to Qingyun, "Take a look, can you see something?"

Qingyun clamped the scope, closed his left eye pretending to be sophisticated, and looked with his right eye.

"Ouch!", he jumped up with a bang, and almost dropped the scope in his hand in shock.

Qing Yun looked into the distance as if he had seen a ghost, and everyone followed his gaze, only to see Miss Mo Chou walking over a hundred paces away.

Just now Qingyun was unprepared, picked up the lens tube, caught off guard, two soft clouds rushed towards his face, which frightened him a lot.

"Be careful!", Di Zhi felt sorry for the scope, and almost snatched it from Qing Yun's hands.

"Wait!", recalling the scene just now, Qingyun quickly raised the scope again, muttering non-stop, "Hey, three inches! There's still more than three inches!"

"What three inches?" Liu Ying asked puzzled.

Qingyun didn't answer, and handed him the scope instead.

Liu Ying took a look and was stunned!Two red lines gradually seeped out from his nostrils, "Three inches, three inches! Damn, fifth brother! You!"

Liu Ying casually handed the scope to Yin Seke, and went after Qingyun.

"I didn't do it on purpose!" Qingyun yelled and dodged.

Yin Seke was puzzled and didn't understand what the two were arguing about.

When she raised the scope, she also let out a cry of surprise, and quickly covered her chest with her left hand, as if to hide her embarrassment.

There is a scale in this scope!

Miss Mochou's most proud curve is infinitely magnified by the scope, and the distance of a hundred steps is as close as breathing, and can be detected visually by a little comparison, and the difference between peaks and valleys is three inches and zero!

Yin Seke tightened his skirt again, trying to make the places that should stand out more obvious.

Looking at Miss Mochou's size, Junior Sister Yin was really afraid that Qingyun, a scumbag with two legs, would look down on her and despise her.

"What the hell are you doing!", for the stalk of Sancun, Li Zhi couldn't touch the veins at all.

It's not because of his low EQ. There is no suspense for Princess Rouran, who is in love with her bitterly, to break through this value. This is something she is used to... It's just that he doesn't know where he is at this moment.

A hundred steps is not a very long distance.As Miss Mo Chou kept approaching, Liu Ying had no choice but to put away her ferocious face, and finally bared her teeth at Qingyun, then met Miss Mo Chou docilely, and took the food basket in her hand.

Qingyun took this opportunity to discuss the scope with Jizhi, "Why do you need to increase the scale?"

"Fifth brother, I'm afraid I forgot. When we discovered the silkworm silk that day, I said that I would use it in the scope. You see." He took out the crossbow machine and put the scope and weathervane on the crossbow on board.

The fuselage of the crossbow has many fine-tuning organs, and the inclination height of the lying bow and the angle with the axis can be adjusted.

"Master and father want to give this crossbow absolute precision, so aiming the sight glass needs to be considered not just aiming, but correction. The crossbow is stronger than the bow, but the range is smaller than the bow, mainly because the bow is a parabola. .We want this crossbow to have a range beyond the bow, so we also need to use parabola. So first, we need to make parabola compensation according to the distance.

If you want to know the distance, visual inspection must be inaccurate. We use the comparison method.Because the length of human faces is mostly about seven and a half inches, we only need to compare the length of the human face in the mirror with these scale lines to know which height the elevation angle of the crouching crossbow should be adjusted to.

After the distance compensation is completed, we also need to consider the compensation of the wind direction.Because the material of the arrow has not been finalized, we have not done quantitative experiments, only the compensation scale is drawn in the scope, and the corresponding left and right inclination gears have not been fixed yet.

Wind direction compensation mainly depends on two aspects, one is to understand the upwind and left and right offset compensation according to the wind vane.However, the wind speed changes in real time. During the aiming process, our line of sight must be concentrated in the scope, so the second confirmation of the wind offset must be carried out through the hairspring in it.The gossamer is made of leaf tone silk, which has excellent toughness, is not easy to break, and is sensitive to left and right wind direction feedback.According to the horizontal scale of the hairspring drift, we can accurately grasp how to slightly adjust the aiming direction at the moment when the trigger of the crossbow is pulled.
