On this rainy day, Shi Qing couldn't wait to bring his newly developed glider to Xuanwu Lake, and the good deeds in the city hugged each other, followed to see Shi Qing's "flying sky", and there were thousands of followers, so lively.

After the first two failures, Shi Qing found some tricks from the failures, and this time his confidence was greatly increased.

His glider wingspan is nearly two zhang wide, with multiple layers of silk as the surface, in order to reduce the weight of the glider, but to ensure the strength, in the choice of the skeleton, he can be described as painstaking.

He first used the irons as the skeleton, but the irons were too heavy;

Copper pipes are also used, but they are not strong enough and the price is too expensive.

Next, he tried to use the skeleton of Gangzhu, which is the toughest among all kinds of bamboo, and the old bamboo with yellow skin is cut down and roasted with fire;

First, to roast the water of the bamboo and reduce its weight;

Second, the roasted bamboo will become tougher and plastic, and if it is painted with tung again, it can be insect and antiseptic, and durable.

The result of trying rigid bamboo is that the dead weight of the glider is greatly reduced, but the bamboo is hollow, the wingspan is slightly larger, and it is still relatively easy to break.

Shi Qing improved again, using thinner bamboo, opening up the bamboo joints, and stuffing an iron bar with the thickness of a little finger into it;

In this way, the dead weight will not increase too much, and the strength of the skeleton will be greatly improved.

It's just that it's more cumbersome to make, and the cost has increased a lot.

That day, Shi Qing happened to see Qin Liangyu's car passing by, this strange woman was highly respected by the world, and Emperor Chongzhen even wrote such a poem to praise her: Shu Jinzheng robe is cut by itself, and the peach blossoms will be long immediately. How many strange men are there in the world, who is willing to travel thousands of miles on the battlefield?

Today's Great Qin royal family is so popular with the people, Qin Liangyu, the "imperial sister", has played a great role in it, that is, the Donglin Party who looks down on the generals the most, and also respects her very much.

When Shi Qing saw her car, she suddenly remembered her world-famous white pole soldiers. Then I came up with the idea of using ash rods to make the skeleton of the glider.

The ash rod is as white as jade. Hard but not hard, tough but not broken, the shaft can be bent to 180 degrees without splitting, its flexibility is incomparable to other wood, often used to make spears, can resist sword slashing.

Thinking of this, Shi Qing couldn't help but slap himself twice, why didn't he think of the ash rod in the first place?

The ash rod was easy to find, and Shi Qing was overjoyed, so he immediately went back to use the ash rod as a skeleton. But after making it, it is not ideal, the ash rod has good toughness, but it is too soft, and it is easy to bend after being stressed, so that the glider is deformed as a whole, and it is difficult to get a good lift.

Shi Qing was indomitable, and carefully consulted various books, in the "Arm Record" of the Han Wu Zhen. He found this record: "The gun material is Huizhou cattle tendon wood as the top, and the sword spine wood is secondary, the red edge is strong and straight, and it is fragile." The ash is soft, and the sticks are also. ”

The difference between a stick and a gun is that in addition to the function of a stick, the gun mainly stabs the enemy with the head of the gun. Therefore, it cannot be as soft as a stick, in addition to the toughness of a stick, it must have a certain hardness to be suitable for stabbing the enemy.

From this account. It can be seen that cow tendon wood is the best choice for gun materials, so in addition to its flexibility, its hardness must be stronger than that of ash rod.

Today, the reason why Shi Qing is so confident is because of the latest production of two gliders. One is to use cow tendon wood as the skeleton, whether it is hardness, toughness or weight, it is very ideal. One is based on a rigid bamboo iron core as the skeleton, which has a slightly larger weight but stronger strength.

Shi Qing believes that one of the two must be able to do it.

The wind blows in April, the mountains and rivers by Xuanwu Lake are beautiful, and the water birds are flying. Thousands of people came with Shi Qing at once, making the beautiful Xuanwu Lake lively.

The people around him were gossiping and discussing, and someone joked to Shi Qing: "Shi Dianshi, you should change your surname first, your surname is too heavy to fly." ”

"Yes, yes, change your surname to Mao."

"Mao is not good enough, change your surname to Feng."

"If you want me to say that I should change my surname to Yun."

"According to what you say, can't you just let Concubine Xiang fly directly?"

"How dare you say that?"

"What don't you dare, Concubine Xiang is beautiful and kind, she should fly like a fairy."

"Uh, you sycophant, I'm convinced."

"Hahaha stone pawn, this time you can fly with confidence, and then plant it in the lake, and we will fish you up immediately."

Shi Qing was busy with a dozen assistants, and after listening to the joking voices around him, he couldn't help but reply: "Why should I change my surname?" Just surnamed Shi, fall down and smash you cheap guys. ”

"Shi Dianshi, I'm afraid that you will fall into the lake and sink straight down."

"This time, you wait and see, if I fly, you all change your surname to Shi, do you dare?"

"If you don't dare, just forget it with the stone ceremony, the stone code thing will fly up first, and then talk about it, I'll go find a boat to prepare for the salvage of the stone codex."

"Hahaha"

Today, the east wind is tight, after installing the glider, Shi Qing pulled up against the wind, and immediately felt that the glider was pulled up by the wind, making him almost unable to stand, seeing this situation, he was more confident.

The shore of the lake is three feet above the water, and with the wooden runway, it is about two meters above the water.

The crowd became more and more excited at this time, and all kinds of chatter, strange screams, and laughter filled the ears.

Shi Qing's heartbeat also began to accelerate, but don't plant directly into the lake like the previous two times.

He took a few deep breaths and pushed the glider to run, but he pushed too hard and was carried off the ground by the glider before he could reach the lake

"Ahh Fly, fly! ”

"Oh my God, the stone canons are really flying."

"Yo ho!"

The thousands of people watching the excitement by the lake all widened their eyes, watching Shi Qing fly up, all kinds of silent exclamations, and unnutritious shouts, which suddenly resounded in Xuanwu Lake.

This is the first time to fly, Shi Qing's own excitement is indescribable, but in terms of controlling the glider, he is not very familiar with it, and in the excitement, he also forgot what Qin Mu said, through guò appropriate dive to increase speed and gain lift, as a result, flying out less than ten steps, the speed slowed down, the glider began to fall, and when he wanted to adjust the angle to dive, he had already fallen to the water.

"Ahh

"Oops!"

"It's a pity!"

When the crowd on the shore saw him fall into the water, they immediately let out a wail, and the voices of regret came and went.

Shi Qing's dozen assistants had already prepared, rowing a small boat to work him and the glider together.

Shi Qing was not discouraged, changed his wet clothes in the cabin, and then went ashore, just now he flew the glider with a strong bamboo iron core, the one with a large dead weight, he could fly, this time he wanted to fly with cow tendon wood as the skeleton;

The glider made of the cow-tendon wooden skeleton was lighter, and he didn't even bother to pay attention to the messy mouths on the shore, looked at the wind, took a few deep breaths, and then set off.

With his experience from last time, he didn't run as fast this time and jumped from the jump at an even speed while focusing on the controls.

The crowd on the shore looked at him like a big bird, fluttering across the lake, and the picture was so beautiful that people hardly dared to look at it.

But I couldn't help but look at it with round eyes;

At this moment, there was no sound on the shore, and everyone was about to suffocate.

Some people even unconsciously spread their arms and learned the movements of Shi Qing's flying, as if their armpits were windy and flew with them.

Shi Qing flew out for more than ten feet, his heartstrings tightened, trying to fumble his way to control the glider, he watched the clear lake continue to retreat below him, the feeling was indescribable, and his eyes couldn't help but be soaked with tears

From time to time he swooped down to speed up, and then, like the swallows he usually saw, rose gracefully in the wind, and only then came the sound of cheers from the shore, and the people shouted and jumped as if they were the ones who had flown up.

This time, Shi Qing wanted to rise higher, and the angle of the dive was larger, which suddenly caused a stall and plunged into the lake from a height of more than ten meters.

"Ahh

"What's wrong?"

"What's going on?"

Suddenly there was another screaming and wailing on the shore, as if the most beautiful dream had suddenly been shattered.

Shi Qing, who was planted in the lake, was quickly rescued by the boat, but fortunately he was not seriously injured, as soon as he got on the boat, he couldn't help but scream and jump, and he looked like a madman with excitement.

He knew very well in his heart that this planting had nothing to do with the glider, but his own control error, and he believed that as long as he flew a few more times and continued to explore and sum up experience, he would be able to fly freely in the sky like a bird.

Flying, the ever dream of mankind, has finally come true in itself!

Shi Qing couldn't help but look up to the sky again and shouted and laughed, his excitement was indescribable
