His Majesty is a sick beauty

=====================

After Wang Gonggong got the order, he snorted and brought over a large box in person. Su Xun thought that Wang Gonggong was too slow, so he went out in person, grabbed the box in his hand, and walked to the table in three steps. , and threw it on the table with a bang.

Conan frowned when he watched the little emperor roll up his sleeves boldly, and then lowered his head again. The blueprint that was boasted just now that it could change the national power of the Yu Dynasty was half suppressed under the box.

Conan:  …

He saw that Su Xun took out a half-burned candle with a dragon pattern on it, which was obviously found in the bedroom, and a wooden board that was obviously left over from something, and there was a small crooked hole on it. An iron ruler, the only thing that fits the status of the little emperor is a palm-sized crystal triangular pyramid, with no decorations on it.

Conan:  …

Su Xun looked at the pile of things in front of him and clapped his hands proudly.You must know that most of these things were prepared by him, the candles were pulled out by him himself, and the wooden boards were the scraps left over from making the hand crossbow before, and he picked them up and drilled the holes himself.

It seems that I have not been corrupted by the extravagant style of being served by people in everything in ancient times. My hands-on ability is still very strong!

Ignoring Conan's indescribable expression, Su Xun recalled the knowledge he learned in junior high school while placing the equipment in front of him.

That's right, he wants to show Conan the scenic spot in the classic optical experiment - pinhole imaging!

One of the inevitable experiments in physics class that has tortured countless junior high school students, it intuitively shows the important law that light travels in straight lines!

Su Xun ordered Wang Gonggong to cover the windows with wooden boards, and in an instant, the whole room was dark.Su Xun lit the candle, and set the wooden plank that had been dug before on the table.

"Wang Gonggong, help me get this piece of silk."

The internal construction department can only make small pieces of flower paper now, and how to make large pieces of white paper is still in the experiment, so this time Su Xun still used silk as the projection screen.

Conan's eyes widened, and as the little emperor moved the position of the candle, a clear reflection of the candle flame suddenly appeared on the paper in the prince's hand!

"This...this is?"

Conan looked at the impact of the fallen candle, feeling a little numb all over.

"Sir, do you know why all things have shadows under the sun?" Su Xun took out a piece of parchment and drew the principle diagram of the small hole imaging, "It's all because light travels in a straight line, please see, sir, as a candle When the light from the candlelight passes through the small hole, the light from the upper half of the candlelight passes through the small hole and shines on the lower half of the silk, and the light from the upper half of the candlelight passes through the small hole and shines on the lower half of the silk.”

"In this way, an inverted image is formed on the silk."

"So the shadow is formed because the object blocks the light that travels in a straight line?"

Su Xun nodded. As expected of the person recommended by the national teacher, his comprehension ability is super strong.

He added: "There is also the rainbow after the rain that I told my husband before, please look here, sir."

Su Xun took out a transparent triangular pyramid. There was no glass at this time. This triangular pyramid was made entirely of large crystals, which made the poor emperor feel distressed.But when I thought that once the person in front of me was recovered, maybe I would soon have a high-temperature furnace, and then I would have as much glass and steel as I wanted, so I was relieved.

Su Xun ordered Wang Gonggong to remove a piece of wood that had previously blocked the window. Su Xun deliberately chose a west-facing window, which happened to have direct sunlight shining into the room at this time.

He put the triangular prism in front of the beam of sunlight, and turned it slightly, and a shocking scene appeared. After passing through the prism, the original warm yellow sunlight turned into seven bands of light from red to purple!

"The rainbow dragon has appeared!" The moment Wang Gonggong saw the seven-color light belt hit the ground, he knelt on the ground, and his body couldn't stop shaking, as if he saw some extremely terrifying creature generally.

Although Conan was not as reactive as Wang Gonggong, his face was pale and his sweat was dripping down.

Su Xun didn't expect that just a light dispersion experiment would have such a big impact on ancient people. He quickly put away the triangular pyramid, for fear of frightening the chemist he was optimistic about.

Conan hesitated for a while, then said with trembling lips: "This is, this is the truth of the rainbow dragon's appearance after the rain?"

The little emperor nodded.

Conan glanced at the prince who was kneeling and shaking on the ground, stretched out his sleeve to wipe the sweat from his forehead, and said with a wry smile: "Next time your majesty does this again, it's best to say hello to others first."

Summoning Honglong at the slightest disagreement, this was done by the little emperor, if someone else did it, he might be beheaded if he found out.

Su Xun did not expect superstition to be so serious in this era, and even Conan, who had begun to doubt the existence of the rainbow dragon, could not accept this experiment.

At this time, the prince had already recovered, he knelt on the ground and rubbed against Su Xun's feet, grabbed the hem of his clothes and cried: "Your Majesty, Your Majesty is really the Son of Heaven, Your Majesty, how could Your Majesty summon the rainbow?" Long, this is the blessing of my Great Yu, Your Majesty! Your Majesty really is where the fate lies and where the hearts of the people lie!"

Su Xun was shocked by Wang Gonggong's superstitious and nasty compliment. He looked at Wang Gonggong who was so excited that his face was full of tears, and quickly asked someone to help him up.

The young ladies heard the sound and walked in, and they were stunned when they saw the prince who was crying so much that his tears and nose were all smeared in one place.

"Hurry up and wash the prince's face and let him drink some hot tea."

Wang Gonggong also knew that his current appearance was not suitable for continuing to serve in front of the imperial court, so he hurriedly left after apologizing.

Su Xun still reassuredly warned from behind: "Don't say anything about this matter!"

After Wang Gonggong's trip, Conan also slowed down.

He thought for a while: "So, in fact, there are seven colors of light, and these seven colors blend into one body to become colorless and odorless light. After the rain and in front of the waterfall, because of the transparent water droplets floating in the air, it is just like your majesty before. Like a triangular crystal, it scattered the mixed light?"

Boss, the ability to summarize is really strong!

Su Xun nodded in admiration: "Exactly."

Conan's eyes lit up again: "Your Majesty, why do people see things in the water from the shore?"

"As I said before, light travels in a straight line, but in different media... oh, the situation of propagation in different transmission objects will change slightly. People see things in water, and light travels from air to water, so it will naturally A deflection occurred."

Su Xun's physics in junior high school has been useless for a long time, and most of them have been returned to the teacher. At this time, he can only explain vaguely.

However, Conan was obviously very fascinated by it. Hearing the little emperor's words, he felt like he had found a treasure, and he seemed to be eager to experiment in the next second. What happened when the light entered the water from the air.

Su Xun looked at Conan, whose appetite had already been whetted by him, and felt that the time was ripe, so he said, "Then, sir, are you interested in becoming a doctor?"

"PhD……"

Conan had a premonition that this would be a decision that could change his life, just like when the white-haired boy with cold eyes stood in front of him ten years ago and invited him to enter Taoism and become his junior.

He only saw the handsome young man in front of him nodding his majesty, his eyes were sincere and clear, and he never showed any hint of ridicule because of his ugly face from the beginning to the end.

He said: "I want to build a Ge Museum, recruit talents like Mr., study the principles of all things, record them in a book, and pass them on to future generations."

"I hope that when I am in power, I can get a machine that can weave cloth for one person, farm tools that can cultivate several acres of farmland with a few people, and even cattle and sheep that can be slaughtered in a year, and a mu of grain that can produce a thousand catties."

"I hope that when I am in power, the sea will be clear and the rivers will be clear, the world will no longer suffer from cold and starvation, those who work will not worry about food, and those who are eager to learn can get the books of the world."

"Sir, would you like to create this prosperous world with me?"

Conan knelt down, put his hands on the ground, and knocked his head deeply on the ground: "Minister, command."

Su Xun breathed a sigh of relief. Just now, in order to strengthen his momentum, he braced his shoulders tightly and even used the standard military posture during military training. At this time, when the force was relieved, the muscles of the entire back trembled a little. .Moreover, he stayed in the field for a while this afternoon. Although he was neither sun-drenched nor tired, it still took some energy after all.

He picked up the teacup in front of him, but saw that the water in the cup was trembling slightly.

"His Majesty?"

Conan raised his head, looked at the little emperor's pale face, and frowned tightly.

"I'm fine, I'm sick."

Conan thought that Qinghe had to attack the little emperor every day for consultation, so he couldn't help but said: "Your Majesty should pay attention to your body. I was lying before. Your Majesty is really not suitable for nourishing kidney qi at this time."

Su Xun didn't expect that Conan hadn't given up yet, so he smiled. Although his face was pale, those dark eyes became brighter and brighter.That gaze seemed to cast a kindling in his heart, rekindling his withered heart.

Su Xun took a sip of hot tea, took it easy, and continued, "I'm going to grant you a special part of the money. You can help me think about how to improve the smelting technology. I need cheaper and harder steel to equip. army."

At this time, there is already a bellows, and the furnace temperature of the steel furnace can reach more than 1200 degrees.From the past, there has been a steelmaking process, through repeated heating, folding and forging of iron blocks, to keep the carbon content in the steel at a more appropriate ratio, and the steel produced in this way has a dense structure and uniform thickness .But such a knife would take months, or even years, to be made, and only small leaders of the army were eligible to use it.

If Su Xun wants to obtain cheaper steel products to equip the army, or even manufacture bed ballista crossbows, he needs to improve the existing steelmaking process.

He probably had the impression that in addition to hundred steelmaking, there were actually fried steel and converter steelmaking methods in the later period, but Su Xun had only heard of its name and didn't know how to operate it.

"You can find a few masters of forging knives and observe how they make precious knives. I only know that the charcoal in the iron, that is, some impurities, should be removed by high temperature, but what kind of temperature is required? To what extent is it removed? You need to study it.” Su Xun glanced at Conan with a bitter face, “Don’t worry, you first make a list for me, what do you need, money, helpers, etc. Once it is done, it will be a great thing that will benefit the country and the people.”

Today's knife forging skills are all secrets, not to mention him as an outsider, even the second son in the family sometimes won't tell it, and will only pass it on to the eldest son.Conan's enthusiasm made Su Xun's request cool down for the most part.

"Don't worry, I didn't ask you to get out a hundred or eighty treasured swords at once. As long as there is a little change to make it easier to obtain steel, it is all thanks to you."

Su Xun blinked, and unceremoniously made a big deal for his employees: "At that time, I will make a decision and let the historian do a separate biography for Mr.

The little emperor's flatbread looks pretty, but it's really hard to eat.

Conan smiled wryly and asked, "I have the courage to ask Your Majesty, who else is in this museum besides me, so I might as well pay a visit in advance."

Su Xun: ...the department that just popped up in my mind half an hour ago, how can there be anyone else.

Suddenly realizing that although he was appointed a high-ranking official, he was a polished commander, Su Xun smiled a little embarrassedly: "I would like to be a pawn for you, sir."

Invent this, I am willing to be your little brother~

Conan:  …

Your Majesty, the cake is not painted like this!
