Chapter 111 Why didn't you tell me earlier that a beautiful lady was coming?

When Wang Jing called him, Li Mo stood up happily, puffed out his chest, and answered seriously, "The teacher once said that everything in the world has three forms, solid, liquid, and gas."

Little Black Charcoal Head originally had no name. His father was from Luoyang and was an old soldier of the Tunqi Battalion who had followed Wang Jing. During the rebellion in Hedong, he unfortunately died in the battle of offering sacrifices to the golden man to heaven to punish Yu Furuo.

The little guy just turned nine this year and is now raised by his mother. Thanks to the pension issued by the army and his mother's job on a veterans' farm, the family lives a decent life. He was even selected as one of the first students to attend the college.

Wang Jing naturally had to take good care of such a military martyr's family, so after learning about the situation, he personally named the little black charcoal-headed boy "Mo" and placed high hopes on him.

Li Mo did not disappoint Wang Jing and his mother's expectations. He was active and studied hard in the academy. Although he was not the smartest child, he was the most active and hardworking one.

Wang Jing was very satisfied with Li Mo, nodded and smiled: "Well said, then can you give a specific example to illustrate the changes between these three states?"

As if responding to Wang Jing's praise and expectation, Li Mo's eyes instantly became brighter, and he raised his head and continued, "Sir, you used water as an example before, saying that at low temperatures, water will freeze, which is the process of changing from liquid to solid. If you boil water with firewood, it will turn into steam, which is the process of changing from liquid to gas."

Wang Jing was very happy that Li Mo really remembered his words very well.

Outside the classroom, the three girls also heard the answer. The simple and easy-to-understand truth made them understand it immediately.

"Oh, it's so simple, why didn't I think of it?"

Huang Xin was a little unconvinced. After all, she was a lady from a prominent family. Even if she wasn't knowledgeable, she was at least well-educated and well-mannered. But now she actually lost to a little brat who looked like charcoal?
It’s so shocking!
Although in Wang Jing's eyes, this thirteen-year-old loli is not much older than Li Mo, they are both little kids who have not grown up.

Cai Yan, on the other hand, was not surprised. She covered her mouth and chuckled. She just felt it was novel and interesting, and developed a strong curiosity about the "truth of the great way" that Wang Jing talked about.

In fact, she often talked with Wang Jing before, so she had been exposed to a lot of scientific viewpoints and knew more than Huang Xin and Yuan Ying. At this moment, she said to Huang Xin: "Sister Xin'er, the answer to this question seems simple and easy to understand, but in fact, if you want to summarize it, you must go through long-term observation and thinking. It's normal that you can't answer it."

Yuan Ying was very curious: "Why is this Mohism different from what I imagined?"

Her grandfather was Taifu Yuan Wei and her father was Yuan Yin, so she received a complete Confucian education since childhood. She is serious about heaven and earth and has her own logic.

Yuan Ying had read many classics handed down from the Middle Ages at home, and was not completely ignorant of the various schools of thought. However, after all, Mohism was no longer a popular school of thought in the Central Plains at that time. Therefore, Yuan Ying's understanding of Mohism was only about some superficial concepts such as "universal love" and "non-aggression", but she knew very little about the study of things.

After listening to this, Cai Yan was also puzzled: "Although studying these things is also very interesting, what is the point?"

With doubts and confusion in mind, she and her sisters continued to eavesdrop.

In the classroom, Wang Jing brought out a wooden basin filled with water. In addition, there were three other things, namely wood chips, stones and a small iron boat.

"Today I'm going to teach you something new, specifically about the existence of buoyancy."

Wang Jing smiled and asked, "Do you know why boats can float on the river, but stones will sink to the bottom when they enter the water?"

This question obviously stumped everyone.

Even Cai Yan and the other three people outside the window frowned in deep thought and began to scratch their hair in distress.

Wang Jing did not let everyone ponder for too long, but instead conducted the same buoyancy experiment as Archimedes, and then took this opportunity to explain that buoyancy is related to the density of matter.

The children suddenly realized: "So that's how it is, the teacher is really smart!"

Wang Jing smiled and shook his head: "This has nothing to do with being smart or not. The key is that if we want to explore the mysteries of heaven and earth, we must have a heart that seeks truth from facts. If you want to gain knowledge, you can't just search in the piles of old papers left by your ancestors, you must think and verify it yourself, so that you can embark on the road to truth."

This sentence was too profound, and the children only half understood it. Wang Jing did not force them to do so. He just hoped to plant a seed of pursuit of science in their hearts, waiting for it to blossom and bear fruit one day.

"So, does anyone have any questions about buoyancy?"

Wang Jing looked around, but no child raised his hand.

On the contrary, outside the window, Cai Yan couldn't help but ask: "I have a question!"

Wang Jing smiled and greeted, "Zhao Ji, long time no see."

"Meet Lord Qi."

Because it was a public occasion, Cai Yan bowed and addressed Wang Jing by his title.

Today, she wore a light pink silk floral dress, and she was beautiful. Although she was not as stunningly beautiful as Diao Chan, she had pure literary talent, and was elegant, refined, and graceful, which made her stand out among the crowd.

It is like a bell flower that symbolizes talent, beautiful and elegant, making people unforgettable upon seeing it.

"Why do you and I have to be so formal? Just call me by my courtesy name as before."

Upon hearing this, Huang Xin and Yuan Ying looked at Cai Yan angrily. Their fierce eyes seemed to be questioning why she didn't tell them about her acquaintance with Wang Jing earlier!

Wang Jing would naturally not refuse Cai Yan's request for advice, so he looked at her with a friendly expression and said, "What does Zhao Ji want to ask?"

Beside Cai Yan, the two little girls clenched their fists and seemed to be even more nervous and excited than she was.

As for Cai Yan herself, she was not under any pressure and asked the question in her mind in a relaxed tone: "Yuan Xu, you just said that fluids have buoyancy. This can explain why wood can float in water. It should be that the density of wood is lower than that of water. For the same volume, it is not as heavy as water, right?"

"Well, that's a valid point, what's the problem with that?"

Wang Jing smiled and nodded. With his gentle temperament, handsome appearance, and the interference and influence of the Destiny Emperor Star on his thoughts and energy, Wang Jing's smile seemed to glow, which was extremely attractive to women.

Yuan Ying and Huang Xin had weaker spiritual cultivation and were instantly obsessed with Wang Jing's "beauty".

This is because Wang Jing has completed six refinements of "Nine Refinements of True Yang". His whole body is in place from the inside out, becoming increasingly close to perfection, and he has a fatal attraction to the opposite sex.

After all, humans are still animals. Their bodies are affected by pheromones such as hormones, and they instinctively want to pass on stronger genes.

At this time, Wang Jing was getting closer and closer to the category of "perfect human being".

The opposite sex with weaker cultivation would feel weak in the legs and dizzy when being looked at by Wang Jing. Their minds would be overwhelmed and their bodies would feel warm, as if there was a hot current in their bodies that wanted to burst out.

Among the three women, only Cai Yan, who had practiced the Phoenix Feather Immortal Sound, had a perfect spirit and could keep her mind clear and unaffected by Wang Jing's charm. She continued to ask calmly, "Then Yuan Xu, can you explain why birds can fly in the sky? Is it because the density of birds is lower than that of air?"

Just now when Wang Jing was explaining the three states of matter, Cai Yan already knew the concept of air, and immediately understood and accepted it. She could even draw inferences from what she had learned and use it to ask Wang Jing questions in return.

It can only be said that Cai Yan is indeed a talented woman. Even though most of her IQ points are in literature and vocal music, her ability to understand science knowledge is far beyond that of children like Li Mo. She asked a rather difficult question as soon as she opened her mouth.

Why can birds fly in the sky?
Before humans understood fluid mechanics, this question was simply impossible for many people to answer.

However, fluid mechanics is a bit beyond the scope of physics beginners who have not yet fully mastered classical mechanics, and it is not easy to explain it clearly.

So Wang Jing smiled and said, "The principle that allows birds to fly into the blue sky belongs to the advanced application of mechanics, which I call fluid mechanics. Only after some of you are admitted to the academy can you come into contact with this subject and learn and master the principles behind it."

"Oh, that's boring!"

Huang Xin, whose curiosity had already been aroused by Wang Jing, pouted in dissatisfaction, looking oddly cute.

Cai Yan also looked at Wang Jing in astonishment, and then asked the question in her heart: "Yuan Xu, you are so evasive, do you not know, or do you simply don't want to say it?"

Wang Jing turned his head, a gentle smile appeared on his handsome face: "Zhao Ji, it's not that I don't want to speak out. In fact, the truth has been written in the mechanics chapter of the Mohist Classic. It's just that if you want to truly understand the content, it's difficult to do so without sufficient basic knowledge."

After hearing Wang Jing's words, the three women couldn't help but show disappointment on their faces.

Li Mo and other students in the Mo Academy were secretly encouraging themselves, determined to study hard, strive to enter the academy as soon as possible, and learn why birds can fly. Seeing that everyone looked disappointed, Wang Jing had an idea.

Haven't I been thinking about how to promote the physical version of Mohism with some added ingredients recently?

In order to achieve the status of the God of Mechanics and the Emperor of Gravity as soon as possible, Wang Jing now feels that conducting a physics experiment that can fly into the sky might be a great idea?
The more he thought about it, the more feasible it became!

After all, humans have had a strong desire to conquer the sky since ancient times. Among the martial arts, Taoist arts and holy words of this world, there are many means that can allow people to stay in the air for a short period of time, such as the body movement martial arts "Six Wings Riding the Wind" practiced by Wang Jing, the Confucian body movement secret art "Rise to the Clouds", and in Taoism, there are even more means of flying.

Even among the various schools of thought, there was Mozi who spent three years making a wooden kite that flew into the sky. There was also Lu Ban, who was knowledgeable and talented, skilled in craftsmanship and production, and he also made a wooden kite that flew for three days and three nights.

The so-called wooden kite is actually a kite. The two of them gained great fame with this unique skill and became prominent spiritual masters.

With such a successful case, how could Wang Jing not be tempted?

Doing a buoyancy experiment is not a difficult thing, but this action shocked the whole Luoyang and set off a trend of studying physics and Mohism.

This deal is really a good deal!
Therefore, Wang Jing had an idea in this regard, and hoped to use the fame of the Cai, Yuan, and Huang families to spread the news for him. Therefore, he smiled and said to the three women: "In fact, if you want to fly, you don't have to be a bird. You can also use other ways to get into the sky."

"Could it be that Lord Qi also knows magic?"

Yuan Ying bravely asked, and even Cai Yan looked at Wang Jing curiously, wanting to know how he would send people to heaven.

Wang Jing walked slowly towards Cai Yan and the other two girls: "It's just flying up to the sky. It's not something that can only be done with magic. In fact, as long as you master the corresponding knowledge, even ordinary people can fly in the sky as they wish."

As Wang Jing walked closer, Cai Yan's eyelids trembled, her heart beat stronger, and it seemed as if all the pores on her body were about to open up from the hot blood.

Wang Jing grinned, revealing two rows of white teeth: "This is a college. Regardless of your title or official position, you can call me Sir, or just call me by my courtesy name Yuanxu."

Huang Xin and Yuan Ying smiled happily and said, "Then we will respectfully obey your command."

Seeing the innocent little girl looking at him with expectation and admiration, Wang Jing felt relieved: "Okay."

Cai Yan didn't care, after all, she had long been accustomed to calling Wang Jing by his courtesy name.

For people in this era who lack basic liberal arts education, it is too troublesome to promote Mohism and preach to them about the great principles, after all, that is the area where Confucianism excels.

Instead of competing with Confucianists in bragging skills, it is better to use interesting physical phenomena to attract young people from wealthy families.

Seeing that Cai Yan and the others seemed very interested in flying, Wang Jing came up with an idea: "In fact, it's not just birds and insects that can fly into the sky. They don't need any magic at all. In fact, as long as the density is lower than that of air, it's not difficult to fly into the sky."

The three girls already knew the concept of density.

That's why they were surprised. Cai Yan even forgot her shyness and asked Wang Jing: "Yuan Xu, as far as I know, air is invisible. Is there anything lighter than air in the world?"

"Of course there are, and there are quite a few."

Wang Jing's answer was confident and calm, his eyes did not shy away, and it was obvious that he had full confidence in himself.

This proud posture immediately made Yuan Ying and Huang Xin's eyes sparkle with stars, and they were fascinated: "Wow! My heart is beating so fast!"

Even Cai Yan was deeply attracted by Wang Jing's confidence and subconsciously agreed with everything he said, but she still felt a little unbelievable in her heart: "Is Yuan Xu serious?"

"Of course, I can prove it."

"How do you prove it?"

"Haha, just give me two days to prepare. The day after tomorrow at 12:00 p.m., I will be outside the Jinyang Gate in the south of the city to prove it in public."

"Then Yan waited patiently for good news."

After an agreement, Cai Yan took Yuan Ying and Huang Xin to leave Mengjin Academy and head to Imperial College.

"Sister Soji, do you think Brother Wonwook can really prove that there is something lighter than air?"

In the carriage, Huang Xin leaned against the window, looking reluctantly at the small academy that was gradually disappearing from his sight.

Cai Yan pinched the hem of her skirt and said absentmindedly, "I don't know either."

The carriage arrived at the Imperial College, and Ma Riti also learned about this from Cai Yan. He immediately lost interest in the Confucian classics in his hand and could not help but frown and think deeply: "Writing a book and a biography, and going to such great lengths to promote it, Qi Hou, what exactly do you want to do?"

Time flies, and two days pass in a flash.

In the south of the city is the Imperial College.

Its architectural form is square outside and round inside. It was the place where the emperor of the imperial dynasty preached the orthodox teachings and spread education. It was also the highest-standard ritual building of the imperial dynasty, and its use rights belonged exclusively to the emperor.

All the emperors of the Yan and Han dynasties preached in this place.

Taixue is also called Mingtang Biyong. As the sky is called bright, it was named Mingtang.

The upper garden imitates the sky, the lower garden imitates the earth, the eight windows imitate the eight solar terms, the four doors imitate the four seasons, the nine rooms imitate the nine states, and the twelve halls imitate the twelve months.

Among the twelve halls, there are four main halls in the southeast, northwest, northeast and southwest. The south is Mingtang, the east is Qingyang, the west is Zongzhang and the north is Xuantang. Among them, Mingtang can only be used by the emperor.

The outermost part is a circular canal called Biyong.

Historical records record that "the design of the Mingtang is surrounded by water" and that the Biyong is "round like a jade disk and filled with water."

Many students gathered in Qingyang Hall today, including young talents from various major families.

"Zhongdao, how about we go to Zuiyue Tower to have a few drinks to relieve our fatigue? I heard that a new wine has been released recently, and its name is Zuihua Niang. The aroma of flowers is contained in the wine, and the fragrance is fragrant. When you drink it until you are slightly tipsy, you will feel like you are sleeping in a sea of ​​flowers. The taste is really wonderful."

"This... going out to drink wine in broad daylight, I'm afraid it's not appropriate, right?"

"Haha, I didn't ask you. I invited Brother Zhongdao!"

Seeing that several classmates were about to argue about drinking, Wei Zhongdao waved his hand gracefully and declined, "Forget it today. I have to go to see the Minister of Rites later."

As a result, his companions couldn't help but tease him, "I see you are not going to see the Taichang, but to see the peerless beauty, right? I heard someone just mentioned that Miss Zhaoji is coming to visit our Imperial Academy again."

"What? It's Miss Zhaoji!"

Upon hearing Cai Yan's name, many students in the Qingyang Hall couldn't help but exclaim in surprise. It was obvious that they were all Cai Yan's die-hard fans.

In fact, this is not surprising.

Cai Yong was, after all, a great scholar of the time with a distinguished reputation. In the past, he was a big figure who could converse with Emperor Ling and his ministers and discuss philosophy with them. Even if he has fallen now, a lean camel is still bigger than a horse.

For many students whose future is uncertain, if they had a father-in-law like this, even if they couldn't have a successful career in the government, they would at least be able to find a way out, right?
Besides, Cai Yan was born with a beautiful face and was proficient in playing the piano, chess, calligraphy and painting. Who wouldn't want to marry such a smart and talented lady and live with her forever?

Therefore, Cai Yan only appeared in the Imperial College a few times with her father Cai Yong, but she successfully left a stunning impression on many young students.

Now that people heard of her arrival, it naturally attracted a lot of onlookers and attention.
