Before dawn, the right waiter He Chou was woken up by his wife in his sleep, and hurried to the Shaofu to listen to the order. When he came to the official office occupied by Yang Tong, he couldn't help but feel stupid.

His Majesty the Emperor was writing and painting at the table, and several palace maids put a plate of side dishes on the table, and then served a bowl of fragrant multigrain porridge for Yang Tong.

The side dishes on the table, some are crystal green, some are red, some are fried in clear oil, some are pickled in fine salt, there are snow-white flatbreads, oil-baked pies, and a large plate of cold pork ears, sauced meat, barbecued meat, animal offal, and a casserole of multigrain porridge...... It looks like it makes people's tongue flutter and appetite soars, but it seems too shabby, right?

He Chou had some insomnia last night because of a topic, and slept late, and was called by Yang Tong early in the morning, so he didn't have breakfast. At this moment, he smelled the smell of fragrant multigrain porridge, and couldn't help swallowing saliva, and his stomach rumbled softly.

In the midst of his thoughts, he stepped forward and saluted, "Weichen He Chou see the saint." ”

"He Shilang is here!" Yang Tong put down the pen in his hand and asked the palace maids to retreat, and then smiled and said: "I have a plan to fly to the sky, and I think only you can make it successful." ”

He Chou can be called the first master of the three dynasties of the Great Sui Dynasty, he built the Liuhe City for Yang Guang is a masterpiece that can not be copied after the Sui Dynasty, this Liuhe City can be disassembled into parts for transportation when marching, and then assembled into a wooden city with a height of four floors when stationed, and the Liuhe City is also installed with an automatic alarm device called "Strike Police", and a bed crossbow that can be turned, which can be automatically aimed and fired.

Yang Guang's Liuhe City has disappeared in the war, Yang Tong found He Hou in Luoyang, and built another one, this new Liuhe City can be called an upgraded version, the wall panel is not only covered with a layer of iron sheet, but also added iron "loose pages", the scene is a wall, assembled faster. However, Yang Tong has not used and moved in, but simply used it as a technical template for skilled craftsmen to learn and improve, so as not to regret the loss of craftsmanship after He Chou.

Although hot air balloons and gliders do not use all kinds of delicate mechanisms, they are after all things that fly hundreds of meters in the air, and if there is a mistake in any link, the ball will be killed, so all aspects must be carefully and accurately calculated to avoid tragedy; And the most important thing for a master like He Chou is patience and carefulness, so Yang Tong plans to let him handle this matter. It's just that I was too excited, and I didn't even have a drawing to come to the Shaofu Prison, so I could only paint and explain on the spot.

"Fly, Flying Plan? People fly to the sky? Like the eldest grandson, He Chou thought that he was old and decrepit, and he was hallucinating, and his eyes were like copper bells.

He understood the value of Yang Tong's every whimsy, and even turned them into facts one by one, but when it came to taking off, he really didn't think about it, he just felt that the absurdity of the world was nothing more than this.

"Yes, it is to use a kind of utensil to pull people into heaven." Yang Tong said with a smile.

"How is that possible?" He Chou believed that he was not hallucinating, but that this strange emperor really had such a crazy plan, and stammered.

"It is precisely because you think that people dare not think and dare to be the first in the world, that you make automatic warning 'alarms', artificial glass, and labor-saving flyships; In the same way, if you haven't tried it, how do you know that the flying artifact can't be made? ”

"That's just as well." He Chou, a master like him, is the most pragmatic, he thought about it carefully, and suddenly became enlightened, and no longer doubted whether the flying plan would work, but said with an excited expression: "Shengshang, can Weichen read the drawings?" ”

"Don't worry, don't worry, eat breakfast first."

"Thank you, Holy Lord." He Chou knew that Yang Dong was different from the 'first emperor' who paid attention to pomp and circumstance, he was a real emperor immediately, believed in the concept of efficiency first, and acted vigorously and resolutely, so he was not polite, so he followed Yang Dong's gobbling up.

After the two had breakfast, Yang Tong handed over a stack of drawings that had been drawn, He Chou was suddenly excited, and took it respectfully with trembling hands.

Nowadays, everyone knows that Yang Tong is invincible in governing the army and invincible in the army, but only a few people know that this emperor who is proficient in civil and military affairs, and has both poetry and calligraphy art, is still a master of tools, if it is not for the emperor is too busy, He Chou can't wait to discuss the study of organ making tools with him every day.

It's just that when he carefully looked through the drawings of various parts in his hand, the more he looked, the more confused he became... It wasn't until I looked at the final assembly drawing and the overall outline that it dawned on me.

It's a big lantern.

"What do you think of this?" After he finished reading, Yang Tong asked.

"This is a huge Kong Ming lantern, the saint doesn't want to fly into the sky with this thing, right?"

"Not bad."

"Absolutely not, Weichen has never heard that Kong Ming Lantern can bring people to the sky, I'm afraid it can't be hundreds of times bigger... Hey... No, it's not right......" He Chou said this, vetoed his previous statement, thought silently for a long time, and said with bright eyes: "Xiao Kongming can fly into the sky with small objects such as candlesticks, oil lamps, and prayer melon and fruit sachets...... According to this reason, the bigger the Kong Ming lantern is... The heavier the object it can carry to the sky, the more powerful the Kong Ming lantern with a load of one pound is magnified ten times, which is ten catties; A few hundred times is a few hundred pounds... A thousand times is a thousand pounds......"

As he spoke, He Chou stopped abruptly, looking at Yang Tong's eyes full of shock, shock, and deep admiration.

From this theory, this huge Kong Ming lantern can really bring people to heaven.

But throughout the ages, no one has ever thought of expanding the Kong Ming Lantern countless times and then carrying people to the sky.

It just made the saint think of it.

If you don't accept it, you can't.

He Chou was convinced: "Saint, everyone says that you are a heavenly immortal, this is not true at all...... Your whimsical ideas are beyond anyone's imagination! ”

Yang Tong's face darkened......

You're not human, and your whole family isn't human.

However, he also knows that the master of 'science' has always been unsophisticated, but this praise is really unbearable, so it is better not to boast.

"What does He Shilang think is the difficulty of this thing?" Yang Tong didn't come to listen to people's praise, so he said things directly.

"It's not difficult to make this huge Kong Ming lantern. It's just that it needs a high fire to wash it up, which also means that the bamboo strips that withstand the high temperature of the fire and moxibustion, as well as the paper and cloth covered on the bamboo strips, need to be tough, fire-resistant, and high-temperature resistant, and the lower the air permeability, the better. ”

When it comes to the field he is familiar with, He Chou has become very smooth, he has thought it through very thoroughly, and expounded his opinion, "The shelf made of bamboo strips is light and flexible, but after long-term high-temperature roasting in a sealed cage, it will become quite fragile, and if it is blown by a strong wind in the sky, there is a danger of breaking inch by inch; The iron frame is not afraid, but it is too heavy to take it; As for the outer skin, it is even more troublesome, it not only has to prevent being burned by fire, high temperature baking, but also rainproof, so the general paper is absolutely not used for a long time, but with cloth, the dense holes can not retain the heat, can not bulge, and the animal skin is too heavy...... There is also the need to consider the problems of rope tearing, ball cracking, human rattan basket cracking, lack of fuel, etc., any one of which arises, it will either not be able to fly, or it will throw people out. ”

"He Shilang's words are all the key." Yang Tong nodded.

A master is a master, and he explains all the most critical issues thoroughly at once. He was looking forward to the master solving these problems one by one.

He Hou pondered for a while and asked, "How much does the Holy Lord have requirements for the carrying capacity of the manned Kong Ming lantern?" ”

"To tell you the truth, I want to use this Kong Ming lantern to deal with the Yizhou dangerous pass, so a Kong Ming lantern must carry at least five soldiers who are fully equipped and have enough forward arrows, and even hold a large number of fire oil cans, so as to be able to condescendingly launch an attack on the Tang army in Guanshang."

"With its own fuel, it has to be about a thousand pounds." He Chou's two thick eyebrows were almost wrinkled in one place.

He was also a person who participated in Yang Guang's battle of Goguryeo, and knew that tactically speaking, Yang Tong's requirements were not excessive, and even pitifully low, just because there were fewer troops, this Kong Ming lantern would not be able to conquer Xiongguan. It's just that for him, this Kong Ming lantern that carries a thousand catties of weight is a huge problem.

"Exactly." Yang Tong also understood his difficulties, and said with a smile: "But I don't ask you to do it steadily all at once, you don't have too much pressure." You can first make a small hole lantern with a load of 100 catties or 200 catties, and then you tie the cattle and sheep to try, because the creeping of living animals will also produce resistance, so cattle and sheep are more realistic than dead things. ”

"Wechen understood."

He Chou nodded, his eyes were attracted by another drawing, and asked, "Holy Lord, what is this big umbrella with many ropes tied?" ”

"It's called a parachute!" Yang Tong said nonsense: "When I was in the West Sea, the strong wind dragged my big drums away, and the whole person almost fell back, so I thought of this thing. The main components of a parachute are a parachute, a guide parachute, paracords, harnesses, etc. It is composed of textile materials such as parachute silk, parachute rope, parachute strap and parachute line, and some metal parts. This item is a supplement to the Kong Ming lantern, and if the Kong Ming lantern accidentally falls, the soldiers above can use this umbrella to land safely to the ground. ”

"Listening to what the saint said, Weichen thought of something." He Chou said excitedly.

"What?"

"Holy." He Chou arched his hand and said: "Sima Qian wrote in his writings: 'Blind Suo still wants to kill him, so that Shun is painted on the top, and Su Su is set on fire from below. Shun Nai went down with two hats, and went, so that he would not die. ’。 The story he recounts is that Shun once went up to the top of the granary, and Shun lit a fire from below, and Shun jumped from above with two hats and was not burned to death. In fact, we hold an umbrella in the rain, sometimes it is pulled back by the strong wind, if the umbrella is not strong and broken, it is estimated that many times even people with umbrellas are blown away, so if the umbrella is bigger and stronger, theoretically it can also land smoothly from the sky like a paper kite. ”

"It's good that you understand, let's start by hanging small objects and falling down." Yang Tong said with a smile.

"Whoa." He Chou saluted, "And what is this glider?" ”

"The principle of this glider is the same as that of a paper kite or a parachute. It seems difficult, but it is actually as simple as Kong Ming lanterns, safe and easy to learn, as long as you run a few steps against the wind on a suitable hillside, you can soar into the sky. Depending on the flight conditions at the time, the flight of the glider can fly to about 200 zhang. ”

According to Yang Tong's memory, the farthest record of the glider is 480 kilometers, and the highest is 6,000 meters, this data has been personally tested by the Federal Aviation Administration, Yang Dong estimates that 200 zhang is about 600 meters, which is already a very conservative estimate, of course, because of the current materials.

Although this is the case, it still makes He Chou stunned, what is the concept of two hundred zhang?

He couldn't even think about it.

However, the saint drew three kinds of flying machines at once, and the key is that all three of them have the possibility of becoming real objects, and the production method is simple, not nonsense.

"Holy Lord, Weichen can't wait." He Chou's eyes bloomed with fire.

"Then start making Kong Ming lanterns, this is the most urgent thing."

"Whoa."

。。。。

At that moment, the two kings and ministers summoned the best craftsmen, carpenters, blacksmiths, and tailors, and ordered people to obtain a lot of materials.

It took a day to select the materials, and then according to the weight of all the materials, the size of the 'Kong Ming lantern' was calculated, and then the craftsmen made a skeleton from flexible and light things such as bamboo chips, sticks of wood, and old rattan, and then let the tailor sew out a large enough sleeve, and add thin cowhide to the sewing place.

This 'Kong Ming Lantern', which came to be tested, not only brought together the best craftsmen from Daxing Kaitian Courtyard and Shaofujian, but also brought together outstanding craftsmen from Luoyang to participate in the holy martial arts car overnight.

Although there were people who were constantly busy and counted day and night, it took seven days to make the first large-scale 'Kong Ming lantern'.

In fact, the scientific and technological content of the 'Kong Ming lantern' is not high, and the requirements for the process are not high, but Yang Tong has repeatedly emphasized safety, which makes the time almost always on the selection of materials, but fortunately, the "Super Kong Ming Lantern" that brings together all kinds of craftsmen in the Great Sui is finally completed.

In the open space of the young eunuch, this behemoth lay there quietly, making Yang Tong feel in a trance through time and space for a moment.

All the royal families and civil and military ministers who knew that Yang Tong was engaged in the 'Feitian Project' gathered over, looking at this huge 'Kong Ming lantern' excitedly, chattering endlessly, but the heat has not been replenished at the moment, so the appearance is relatively ugly, it looks a little deflated, and it is not mellow... However, everyone also knows that Kong Ming Lantern itself is like this, but there is no dislike for it, and the main suggestion is whether this big guy can fly like a small Kong Ming Lantern.

At this time, He Chou, who was too busy to eat and sleep, looked unkempt, and he bowed to Yang Tong, "According to the requirements of the saint, all aspects of this thing are tightly sewn, and there are no gaps, and the bamboo chips, Zhemu strips, old rattans, and wicker used in the skeleton are also oil-soaked things that have been transported from Luoyang for one or two years. Can it be ignited? ”

"Command a rope to hold it down so that it does not run away. Then ignition! "This is the first test flight, Yang Tong naturally will not let people sit on it, in case of falling from a height of more than ten zhang, I am afraid that it will be difficult to escape the catastrophe of broken bones, so the hanging basket is filled with two big fat sheep weighing 100 catties each.

"Whoa!"

He Chou was just about to order someone to light the fire, and Yang Tong said again: "This big guy has condensed my hard work, and the first fire will come from you." ”

"Thank you, Holy Lord."

Under the envious gaze of everyone, He Chou took the torch and walked towards the big guy step by step.

For some reason, after being busy for so many days, he was as steady as Mount Tai, but at this moment he was so nervous that he could barely walk.

Although he walked slowly, the distance was only like that, and there was always a time when he was finished, and when he reached the iron furnace, he was wet with sweat.

Yang Tong looked up at the cotton-wool-like clouds in the clear blue sky, it was a rare good weather, and said categorically: "Ignition!" ”

"Whoa."

He Chou took a deep breath, and with trembling hands, he put the torch in his hand into the stove of the iron furnace, and the big wick inside quickly burned, but the wick flame was not strong enough, and the heat was not enough for this big guy to go to the sky.

As the oil and coal in the iron furnace gradually burned, a large amount of hot gas poured in from below, and the hot gas with nowhere to vent puffed up the ugly sphere.

After a while, this huge Kong Ming lantern shook gently from the initial to the stunned gaze of everyone, slowly floated upward, stretched the rope connected to the hanging basket, and then shook a few times, and then rose with the hanging basket and the two big fat sheep in the hanging basket......

Suddenly, one after another screams rang out!

Since the beginning of slash-and-burn farming, human beings have had the dream of flying, but they have succeeded for countless thousands of years. And this Kong Ming lantern carrying a big fat sheep weighing two hundred pounds, for people in this era, has the impact of subversive cognition, just looking at this load capacity, it is enough to show that the dream of flying is no longer an unattainable dream.

Many craftsmen burst into tears, proud of having created this "flying artifact" with their own hands!

As the two bundles of ropes on the ground were straightened, the Kong Ming lantern did not float away in the end, and hung in the air for about two moments, until only a full of oil and coal in the iron furnace burned out, and then the big guy slowly landed and changed into his previous appearance again.

With the success of the first time, everyone was full of confidence, and the second test directly got on ten hundred pounds of sheep, filled up with fuel, and the result still successfully took off, and the suspense in the sky for two hours before slowly falling.

"Whoop......"

The underground crowd roared with joy!

"Holy Lord, Feitian is so simple and successful? ......" Yang Gongren, the head of the hundred officials, was shocked in disbelief.

"It's that simple."

"Only the saint would think of using Kong Ming lanterns to carry people, and he also successfully carried thousands of catties, Weichen really didn't know what to say." Yang Gongren was convinced.

Yang Tong said: "In fact, many inventions do not require much high technology, as long as a simple idea can be successful, others dare not think, unthinkable ideas, can always enable human beings to take a big step in the field of exploring the mysteries of heaven and earth." ”

"With this thing, the world's heroes are useless!"

"Not necessarily!" Yang Tong shook his head, walked towards He Chou and Jiang Xingben, who couldn't help themselves and burst into tears, and ordered: "Gather all the carpenters, craftsmen, and tailors, and let them give up everything in their hands and do as much as they can!" ”

"Whoa!" Jiang Xingben and He Chou hurriedly saluted.

He Chou said excitedly: "Saint, this thing has jumped out of the scope of Kong Ming lantern, can't it continue to be called like this?" ”

"Everyone, sit down!" Ye Zhao walked to a bluestone and sat down, facing the crowd with excited faces.

"Let's call it the Flying Divine Boat!" Yang Tong looked at the big lantern and fell into contemplation, this is the lamp of human beings to realize the dream of flying, and it has monumental historical significance for this nation... The name of the hot air balloon is completely inconsistent with Chinese civilization.

"Whoa."

"This flying Shenzhou is a success, but it is only the first generation, just like a small fishing boat, it must be developed into a five-tooth warship flying in the sky, in order to fight in the sky, so we can not be satisfied with the status quo, we need to continue to develop and improve." Yang Tong looked at the many craftsmen and said loudly: "And I don't have much energy to study this thing, and in the future, I will need you to develop the second, third, and fourth generations that are lighter, faster and safer, and carry more people...... and even the 10,000th generation of flying Shenzhou. Once this kind of exquisite flying divine boat comes out, it is enough to make you famous in history. ”

"Holy Lord, rest assured, we will definitely strive for perfection and develop a better Flying Divine Boat." A group of craftsmen saluted excitedly.

From ancient times to the present, there are a few craftsmen who have left their names in history, and they are all legends and craftsmen, and they dare not think about it!

But now that they have a successful Flying Divine Boat, if they can improve it again, they may be able to reach the height of the same class and Mo Zhai.

No one will refuse such a good thing that will leave a name in history.

"In addition, according to the characteristics of the Flying Shenzhou, it should be equipped with a batch of repeaters with lighter weight and longer range." Yang Tong said again.

"Holy rest assured, we will do our best not to disappoint the saint!"

"Good work, everyone!" Yang Tong nodded happily and said, "My reward will not be less, but it cannot be shoddy. ”

The best craftsmen of the feudal era were all recruited by the imperial court, and the official handicraft industry has always been dominant, representing the highest level of many crafts. These skilled craftsmen gathered in the workshops set up by the government, and used the raw materials of the imperial court to design various new weapons and equipment. And these craftsmen present are all the most outstanding existences in various fields of the Great Sui Dynasty.

Many of the new weapons in the Great Sui were developed by these people, and as long as they made achievements, Yang Tong always rewarded them heavily.

"I'll do as I was told." Many skilled craftsmen obeyed the order.
