[There is only one chapter for today.] Starting tomorrow, it's a new volume. 】

On this day, outside the Chongzheng Palace, there was a strange atmosphere.

Whether it is a straight class or an inner servant, they have no intention of guarding the palace gate, and they even ignore the rules and whisper to each other.

The story of flying away only appears in legends, and Xu Zhenjun's ascension to the house is the envy of everyone, but they all know that such beautiful things are not their turn. But something strange happened today, and the ordnance supervisor actually sent a basket to the sky. The thing in the basket was funny, it was a pig. But pigs can fly into the sky, and so can people.

In the rumors in the palace in the past, Han Gang was just a young and promising official, and at most he could say that his future was limitless. But at this time, in the eyes of the palace guards and the attendants, the Han She people who stepped into the hall were plated with a thick layer of mystery, which reminded people of the identity of the disciple of the Medicine King that he had always denied.

Han Gang walked into the hall, and they all listened to the movement in the hall with their ears pricked up.

"Han Qing!" Zhao Ji's slightly hurried voice came from the hall, "Is there a ship in the ordnance prison that can fly into the sky?" ”

"This is true, and the minister named it a spaceship." Han Gang replied in the affirmative. But his understatement seemed to be saying that the matter was not worth mentioning, "But I have only tried three or five times before, and I only dare to load livestock, and it is not yet time to carry people into the sky." The minister was going to wait for someone to be sent to heaven, and then he would report to His Majesty. ”

It turned out to be true!

Han Gang's answer was so refreshing, but Zhao Ji didn't know what to say for a while. He was listening to the report of the privy envoy Wu Chong on the reorganization of the Hebei Forbidden Army, but he didn't expect that halfway through, Han Zhen of Kaifeng Mansion hurriedly asked to see him, and when he asked, it turned out that it was the ordnance supervisor who sent a pig to the sky, which caused a big commotion in Beijing.

The pig flew into the sky, which sounds funny at first glance, but when you think about it, it makes people unable to laugh, and even makes Zhao Ji feel a little creepy.

This is flying!

Wu Chong on the side also felt that Han Gang's actions were becoming more and more unorthodox, so he instilled a lot of alarmist words in Zhao Gang just now. As soon as Han Gang admitted, he stood up and asked sharply: "Han Gang, you don't want to build the plate armor that you have so good at." But doing such a strange thing caused an uproar in the capital......"

"Rare and strange. Insects and birds can fly into the sky, and no one is surprised. Han Gang unceremoniously interrupted Wu Chong's accusation, "If you can see the spacecraft in the sky every day for a month, no one will take another look." The lantern festival of the Shangyuan Festival, thousands of empty alleys every year, the audience is dizzy. But if there are lantern festivals in Beijing every day for 360 days a year, will the people of Beijing still be interested? …… After getting used to it, it's just normal. He smiled disdainfully, "Liu Hedong's "Qian Donkey" article, if you want to come to Wu Shumi, you must have heard of it. The tiger fears the donkey because it does not know the donkey. When he knew that the bottom of the donkey was fine, the donkey would become the food in the belly of the tiger. As long as Jingzhong can be seen every day in the future, and the details are clear, there will be no more today's events. ”

Wu Chong's face turned blue with anger, but Zhao Chong didn't care. He asked anxiously, "Han Qing, how did you make the sky on the ship?" ”

Han Gang bowed to the Son of Heaven: "The minister has already explained this in "Buoyancy Tracing the Source", which is the same as the iron ship. As long as the overall density is less than that of water, the iron ship can float on the water. If you want to float in the air, you just need to be lighter than the air. The reason why a spaceship can float in the air is because it is lighter than air as a whole. ”

"Is there a difference in the severity of qi?" Zhao Ji asked.

"Air is formless and qualitative, and it is a thing. It is a thing, and it has its own weight. The heat is light, and the air cold is heavy......"

"Nonsense!" This time it was Wu Chong's turn to interrupt Han Gang's words: "The world is full of fragrant flowers in April, and the peach blossoms in the mountain temple are in full bloom." The higher the place, the colder it is, how have you ever seen a high place hotter than a low place? ”

"It is precisely because the high places are not cold, so the heat will go to the cold places, which is the cycle of heaven, and the principle of yin and yang complementing each other. If not, how could the spaceship fly? Han Gang smiled: "And the heat can be seen when it rises, just because Wu Shumi is a gentleman, so I don't know." ”

Wu Chong knew that Han Gang had no good words, and was about to attack, but Zhao Ji took a step forward and asked curiously: "What does Han Qing mean by this?" ”

"There is a cloud of etiquette: the gentleman is far away from the kitchen. Wu Shumi is a benevolent gentleman, so he doesn't know what to do in the kitchen. And Han Gang Bucai has heard a little. Even the sturdy maid who burns the fire in the kitchen knows that the heat of the road is going up, otherwise why not repair the chimney underground? Han Gang stabbed Wu Chong sarcastically.

Wu Chong didn't expect Han Gang's tongue to be unforgiving, and his face was even more gloomy: "No matter how simple the principle of the spaceship is. But how foolish the world is, there will be demons who will use this as a battle in the future to incite the world. ”

"If you don't know it, the ship will be a little surprising. However, when it comes to its origin, it is only an ordinary thing that can be seen in the pitch. Han Gang only studied the reason, and then extended it. This is the so-called knowledge of things. Everyone knows that as long as the education is effective, there will be no hiding from the fallacy. If Han Gang took out an iron ship today, I don't know if the world would be surprised? ”

Wu Chong was waiting for Han Gang's argument, and immediately pursued: "If you can really educate all directions, the spaceship will spread all over the world." He turned to Zhao Ji: "I'm afraid that in the future, the walls of the world will be useless, and even the imperial city will be allowed to enter and exit." ”

As soon as these words entered his ears, Zhao Ji twisted his body in his seat uncomfortably, if a thief descended from the sky, the city walls would indeed be useless.

Han Gang seemed to have heard a very funny joke: "The privy is saying that someone can jump from a place higher than the iron tower of Kaibao Temple and sneak into the palace?" With this ability, the Wuzhang palace wall is also unstoppable. ”

"Could it be that the spaceship can only go up, not down?"

"The spaceship is as big as a house. Hanging in the air, perhaps overlooked. But if it falls, as long as he is not blind, who will not see? Besides, the spaceship moves with the wind, like a dandelion, without the wind and without moving, but with the current. It's not like a fellow traveler, you can go wherever you want! ”

Han Gang and Wu Chong were fighting, and Zhao Ji was impatient to listen. After talking for a long time, he didn't talk about the things he cared about. The voice interrupted the argument between the two: "Han Qing! Where does this spaceship come from? What is it for? ”

Han Gang first confessed to the previous faux pas, and then replied: "Back to Your Majesty, it is the common Kong Ming lantern in the market. It's just a hundredfold larger, from a lamp that can only carry candles, to a spaceship that can carry people. ”

"Kong Ming lantern?!" Zhao Ji was extremely surprised, but he had watched Kong Ming Lantern light up and take off since he was a child, and he never thought that he could build a manned spaceship from this.

"It is the Kong Ming lantern that can float in the air when the candle is lit, because the air in the lamp is heated." Han Gang glanced at Wu Chong, whose face was dark, "As long as you look at the structure of the spaceship on the spot, you can also see the doorway in it." The same is often true of things in the world, which seem to be unpredictable, but once they are revealed, they are actually worthless. ”

Zhao Ji didn't expect Han Gang to say so lightly: "Han Qing, the iron ship is just floating water, but the spaceship can fly to the sky......"

"I don't know why Your Majesty said this? To talk about the principle, the spaceship is only the application of buoyancy. If you want to talk about the origin, it is just a slightly larger Kong Ming lantern. Speaking of usefulness, all that can be done is to replace the nest car and watch the enemy formation from afar. Far less than the iron ship, it can drive the overall development of the manufacturing level of military and civilian artifacts related to steel. Han Gang paused, "...... The ministers did not dare to deceive His Majesty, and the original intention of building a spaceship was mostly based on the theory of light and atmosphere, and the principle of things. If it weren't for the fact that this spaceship still had a little function that could replace the nest car [Note 1], the minister would not even dare to do it in the name of the Weapons Supervisor. ”

The confusion on Han Gang's face made Zhao Ji ask himself if he was making too much of a fuss. It's just that it can make people fly, so it's not a big deal......

…… How is this possible?!!!

This is a tool that can make people fly into the sky, and Zhao Ji has only fantasized about it in his dreams, and the gods can do it. Now someone is saying in front of himself, this is nothing at all? Why hasn't anyone thought of it for thousands of years!?

Zhao Ji half-narrowed his eyes and said slowly: "Han Qing is too humble. ”

Han Gang shook his head: "This is Gewu Zhizhi!" It's not that the world is not intelligent, it's just that they don't think about it. The wind blows the grass, the leaves fall and the flowers bloom, although it is ordinary, but it has its own reason. As long as you don't take it for granted, take it for granted, and go to the root of it, you will inevitably gain something. ”

"What Han Qing said is indeed reasonable......

The spaceship built by the Ordnance Supervisor caused a sensation in the capital, far above the previous iron ships and plate armor. Even Han Jiang, Feng Jing and others were speechless for a while in shock.

The spaceship base, which was originally located in the reservoir area by the Bianhe River, was also moved to Xingguofang. And the outside world was boiling, but Han Gang didn't do it at all, and under such an attitude, he became unfathomable and profound in the eyes of the world.

Although there was a lot of noise in Shilin's comments, when Han Gang was facing each other in the Imperial Court, he had already clearly said that the spaceship imitated Kong Ming lanterns. Such a simple truth, I don't know how many people have heard about it, and they secretly hate themselves for thinking of nothing.

At the same time, the success of the spacecraft caused many printing rooms to reprint the original manuscript of "Buoyancy Tracing the Source" overnight. And Zhang Zai's Guan Xue, under the strong promotion of Han Gang, finally walked to the stage of the capital. The four sentences of Hengqu were also spread by word of mouth among the scholars in the capital.

Establish a heart for heaven and earth, establish a life for the people, continue to learn for the saints, and open peace for all generations.

The spirit of these four sentences is magnificent, and they have done everything that Confucian children should do. Suddenly, Hengqu Zhang Zai's fame overwhelmed many famous Confucians, and he became one of the most admired people in Shilin.

Of course, at this time, what attracted the most attention of the capital and even the entire Gyeonggi was the spaceship that was fully renovated in Xingguobang.

In mid-February, half a month after the commotion, the 'manned spacecraft' flew into the sky on the bank of Jinming Pond under the watchful eyes of all people. Zhou Quan, a veteran who lost his right hand in Hehuang, also became the first mortal in this world to set foot in the void.

Looking up at the hot air balloon hanging nearly a hundred feet high, blown towards the lake by the unruly breeze. In the midst of the thunderous laughter, Han Gang smiled coldly.

It's just one step closer to his goal.
