He Yan said he would wait, but Ni Heng couldn't wait.
"You tell me and I'll find it myself!"
Mi Heng was just like a parrot that had just been released into the world. He was thinking about flying well, so how could he go to a tree branch to rest for a while?
He Yan saw that Mi Heng was not the kind of person who could stand his temper, so he decided to find something for him to do first.
Among the seven basic disciplines, mathematics, physics, chemistry, biology, astronomy and earth science are difficult to achieve breakthrough progress because the current theoretical and technical foundations are not very solid. Only "logic" has a very bright future.
It is also the most important basic discipline at present and the easiest to produce results.
Confucianism has the "Six Arts of the Gentleman", and the West also has the "Seven Arts" of ancient Greek civilization.
The so-called "seven arts" are the "three arts" of the Sophists of Athens - rhetoric, grammar and argumentation, plus the "four subjects" proposed by Plato in "The Republic" - arithmetic, geometry, music theory and
astronomy.
Among them, argumentation and geometry both require strong logic, which is also the final soil before the birth of logic.
Mi Heng is famous for his "eloquence". This "eloquence" not only refers to Mi Heng's bad mouth, but also refers to his rigorous logic.
Translation Translation means that Mi Heng can curse people quite well and in a very clear manner.
If you let such a person engage in logic, it would be a perfect fit for someone named Zheng to marry someone named He.
"Since you have this intention, let's discuss it together?"
"Logic" sounds abstract, but that's just because the Chinese sages did not write books specifically on this subject, but integrated this subject into the logic of famous debates.
The most famous among them are the "Three Biao Theory" developed by Mozi and the "Three Confusion Theory" proposed by Xunzi.
In particular, Mozi's "Three Tables Theory" can be said to have directly established the ancient Chinese logic system. The "rational" thinking shining in it was six or seven hundred years earlier than He Yan, the founder of the new school, proposed "rationality".
It's just a pity that after the Qin and Han Dynasties, because the ruling class only respected Confucianism, the development of ancient Chinese logic system was directly restricted by political and ethical thoughts. In its long development, it has basically been within the scope of epistemology and has not been independent from it.
Become a new discipline.
The most terrible thing is that the ancient Chinese logic system was born out of "Mingbian". There is a mixture or confusion in the understanding of logical properties and language attributes, which can easily lead to linguistic ambiguity and logical confusion. This is also the reason why ancient Chinese logic
The important reason why there are no standardized words for learning.
If you want to break away from this framework, you must borrow tools.
Among all tools, the most convenient is undoubtedly "geometry".
The original meaning of "geometry" is "land measurement", and when translated into Chinese, it also means "measuring size", so it is not difficult for He Yan to let Mi Heng understand this.
In addition, the Chinese ancestors have long left gifts for future generations, and the "Pythagorean Theorem" is a good example.
In order to help Mi Heng better understand and explain "logic", He Yan also opened a huge hook for him——
"Do you know what a coordinate system is?"
He Yan looked into Mi Heng's eyes with a smile.
And Mi Heng's eyes had already been ignited with flames.
This is the fire of civilization thirsting for knowledge!

After sending the crazy Mi Heng to a house in Hewu, He Yan rushed back to Sikong Mansion and coaxed Cao Pi like a child.
"Okay! Let's go out and play!"
"How dare he scold me?"
"Then go to the Nulu?"
"How dare he scold me?"
"Take you to make money?"
"He... hmm? What did He Yanqian say he wanted to take me to do?"
Cao Pi was really small-minded. He Yan persuaded him for nearly half an hour before he finally came to his senses.
But after coming back to his senses, Cao Pi became even more angry.
"Growing up, who dared to scold me? Ah? He actually dared to scold me?"
Hearing Cao Pi's words, He Yan stared at Cao Pi with a strange expression.
Cao Pi was a little embarrassed by He Yan, so he had to add: "Who dares to scold me except dad?"
"..."
"And my mother."
"..."
"And Uncle Ren."
"..."
"And you and Cao Jie..."
Thinking of this, Cao Pi became even more sad.
"Okay, you know how bad Mi Heng's mouth is. Dad has been scolded before, let alone you?"
Cao Pi looked at He Yan with hopeful eyes: "Were you also scolded by Mi Heng?"
"That's not true."
"..."
Cao Pi turned his back and hid in the corner alone, drawing circles wildly.
Seeing that Cao Pi seemed to be really traumatized, He Yan sighed: "Let's go, I'll take you to play."
"Nvlu? Not in the mood today?"
He Yan shook his head: "I'm not a nv, I'm taking you to heaven."
Cao Pi turned around and hesitated for a few seconds, then asked with some uncertainty: "Were you scolding me just now?"
"Who scolded you?"
He Yan rolled up his two sleeves and tied them up, as if he was about to do a big project: "It's really God!"
Cao Pi looked at the blue sky and white clouds outside in confusion: "Heaven?"
"Well, God."
He went over and kicked Cao Pi in the butt. He Yan shouted sharply: "Get up and work!"
Cao Pi followed He Yan outside in confusion and started doing handicrafts with He Yan.
First, a huge piece of fine cloth was taken from the Hewu Textile Factory. This fine cloth was more than ten feet long and five feet wide, enough to make dozens of clothes.
Now this huge piece of cloth was thrown into the yard by He Yan. If those people saw it, He Yan would be impeached for the crime of "waste".
After the cloth was spread out, He Yan bought a few barrels of raw lacquer for applying lacquerware. This is natural sap cut from the lacquer tree. It is resistant to moisture and high temperatures, making it an excellent material.
"Cao Pi, apply all these raw lacquers on the cloth."
He Yan's order made Cao Pi doubt his life: "Paint them all?"
"Well, we need to paint both sides."
"He Yan, I know you are rich now, but that's not how money works..."
The price of raw lacquer was extremely expensive, and Cao Pi was afraid that Cao Cao would get angry when he came back after such a waste.
"You don't have to pay!"
Cao Pi then turned around, excitedly picked up a bucket of raw lacquer and smeared it on the fine cloth.
After all, it was He Yan’s money that was spent! Why do you feel distressed?
"La la la la~"
When Cao Pi thought that He Yan's many five-baht coins would disappear every time he applied it, he applied harder with the brush in his hand, applying the raw lacquer thickly and heavily to every place on the fine cloth.
He Yan himself tinkered with the kerosene ignition device.
That's right, He Yan said he wanted to take Cao Pi to the sky, and the thing he used was actually an enlarged version of the Kongming Lantern - a hot air balloon.
The most difficult thing about a hot air balloon is the balloon material and power fuel.
For the former, even He Yan had no choice but to ask Cao Pi to cover the fine cloth with raw lacquer and wait for as long as it lasted.
It's easy to say that power fuel is good. Kerosene was already popular among the aristocracy during the Han Dynasty. Even though the price is still a bit expensive, for He Yan now, is it expensive?
You know, the first hot air balloon in history used straw as fuel...
Without much effort, a kerosene device was completed.
After that, just ask the tailor to cut the fine cloth covered with raw lacquer into a suitable shape, and then put a light bamboo basket underneath, and this simple "hot air balloon" of the Eastern Han Dynasty is ready.
Moving the huge hot air balloon to the field next to Hewu, He Yan specially called Deng Ai, Xun Yu, Chen Qun, Yang Xiu and others over.
Everyone was curious about this behemoth, but they were all a little amused when they heard that He Yan actually wanted this thing to fly.
Only the youngest Deng Ai was looking at the huge balloon of the hot air balloon and thinking about something. His eyes were wandering in his eye sockets, as if he was thinking about the principle.
"ignition."
He Yan did not argue with these people, but directly lit the ignition device between the ball bag and the bamboo basket.
As the air is gradually heated, lighter hot air gradually fills the balloon, and the balloon soon slowly takes on a "flying" posture.
In everyone's shocked eyes, He Yan tied one end of a three-foot-long hemp rope to the bamboo basket, and nailed Xu Hu and Xu Bao to the ground at the other end.
"Remember, you must not let the hemp rope break!"
After repeatedly asking Xu Hu and Xu Bao, He Yan and Cao Pi got into the bamboo basket together.
Cao Pi saw that the previously deflated balloon was filled, and he felt panic and excitement in his heart for no reason: "He Yan, can we really go to heaven?"
"nonsense."
As the balloon gradually became rounder, the bamboo basket He Yan and Cao Pi were on also began to sway.
Cao Pi grasped the edge of the bamboo basket tightly with both hands, squatted in the basket, and stared blankly at the ground only a few feet away from him.
Sudden.
The ground is moving!
Along with this, there were also exclamations from Xun Yu and others nearby.
After a while of jolting, Cao Pi found that his feet were actually light.
When he looked down again, the ground that was only a few feet away from him gradually became distant. Looking blankly to the left and right, he found that there was only a blank space.
"He Yan! He Yan!"
After reacting, Cao Pi grabbed He Yan beside him. When he realized that He Yan was still in the bamboo basket with him, Cao Pi gained some peace of mind.
"Don't shrink your head, stick it out."
Compared to Cao Pi's panic, He Yanxian was much calmer. He stood upright in the basket and looked in the direction of Xuchang.
Cao Pi tremblingly stood up with his trembling legs, but when he finally stood up, the danger of having nowhere to rely on in the space made him squat down again.
"Hiss! Stop shaking!"
Cao Pi's squat made the whole bamboo basket shake crazily, and even He Yan almost lost his balance, and his body fell backwards.
In order to stabilize his center of gravity, He Yan also squatted down, looked at Cao Pi's pale face and asked: "How long are you going to stay here?"
"Squatting here, maybe with a bamboo basket blocking your view, you can fool yourself that you are not in the air."
"But the fact is, you have already ascended to heaven."
He Yan stood up again and continued to look around: "We are already up here anyway. If you don't take a closer look, will you really not regret it?"
In the first half of his short life, Cao Pi was influenced by various things, which made his character full of caution and suspicion.
But no matter how cautious he is, he is still a young man.
And young people are born with great courage.
For example, to women, and to the world.
Cao Pi took a deep breath, grabbed the upper edge of the bamboo basket with both hands again, took a deep breath and strode his horse to move his whole body upward.
At first, he couldn't see anything, and panic was still filling his chest at this time.
After that, familiar trees slowly came into view, and the familiar land returned to sight. Then came Hewu, Xuchang, and the people below who were gradually getting smaller...
The world is still the same world, but Cao Pi sees them from a different perspective.
All the fear, panic, and anxiety slowly subsided the moment Cao Pi stood up.
What replaced it was an unprecedented clarity.
His legs gradually overcame the physical discomfort. Cao Pi gradually straightened his back in the bamboo basket and stood quite stable.
"Oh~~~"
Cao Pi suddenly roared downwards, and the huge sound once again made the hot air balloon a little unstable.
But this time, Cao Pi did not flinch, but instead let out a burst of hearty laughter.
"He Yan! I really went to heaven!"
"Um."
"He Yan! I really went to heaven!"
"I see!"
"He Yan! I really went to heaven!"
"..."
Although it is bound by hemp ropes on the ground, the entire hot air balloon only flies three feet high, which is less than the height of a "stage", but the meaning is completely different.
"Can people really fly?"
Cao Pi smiled, but suddenly started crying again.
With tears in his eyes, he turned to look at He Yan on the other side: "He Yan! People can really fly! They can actually fly!"
Since people can really fly like birds, what else can people do?
Can you run faster than a horse?
Can you live longer than a turtle?
Can it be like that Kunpeng, the water hits three thousand miles and soars up to ninety thousand miles?
Cao Pi didn't know.
But at this time, Cao Pi's world seemed to suddenly have color. He discovered that the road ahead for him did not seem to be just the black and white figures of Cao Cao or Cao Ang, but there were countless roads leading to a colorful future.
The path here is not only limited to the "lessons" mentioned by Jia Xu, but also something more important -
"What a person should have, is also a dream that one can have."
…
"He Yan."
When He Yan's name was called again, Cao Pi's tears had completely flowed out.
"Is this your world?"
Compared with such a world, the world of Cao Pi and almost everyone in this era seems boring and dull.
This has nothing to do with material, wealth, or power.
But the power, freedom, and dreams that have been thrown away and forgotten by everyone.
"Well, that's right."
He Yan looked into the distance: "This is the world that everyone should have."
