Han Ji's eyelids twitched and he thought that if the old gentleman saw Da Langjun's beloved pet, the word "well-behaved" would probably no longer be used.

Shi Zhengran said calmly: "The Duke is so kind to me that I shouldn't have said goodbye. Da Langjun seems to be a smart boy, but when I left Chang'an, I swore not to serve as an official anymore, so the Duke's trip was in vain.

"

This reason is impeccable.

And the rejection was very thorough, not giving Yang Xuan any room to maneuver.

He Lianyan squinted her eyes, thinking that she would turn around and make people stare at the Shi family, so as to vent her anger on the Duke.

Han Ji coughed dryly and said, "Sir, this is not an official career."

Shi Zhengran was startled.

Yang Xuan smiled and said: "I'm just teaching children."

I didn’t ask you to become an official!

Shi Zhengran was a little confused.

The old gentleman's face gradually turned red, and He Lianyan and Han Ji knew that this man probably wanted to refuse forcefully.

Yang Xuan suddenly asked: "I heard that Mr. Shi once said that the earth is round and the sky is not round?"

Shi Zhengran nodded subconsciously, "The theory of a round sky and a square place is ridiculous. If it is a place, why has no one seen the end for so many years? What will happen to those rivers when they reach the turning point of the place? Do they drop all the way?"

Then there were words that made Han Ji and He Lianyan confused.

Yang Xuan listened with great interest.

Shi Zhengran suddenly asked: "Does the Duke understand this?"

Yang Xuan nodded, "On the sea, if the visibility is good, and a ship approaches, the first thing you see will definitely be the sail."

"Wonderful!" Shi Zhengran asked, "Has the Duke of the State seen it before?" He slapped his thigh, "I'm wrong, has the Duke of the State ever seen the sea?"

"I heard it from the fishermen." Yang Xuan remembered that the scroll said that he saw the sail first, which was a lie, but he deceived Shi Zhengran first.

Shi Zhengran smiled and said: "I will definitely go and take a look."

I am doing something wrong!

Yang Xuan thought that the old gentleman was almost fifty, and in this era he was almost considered a birthday boy when he went to sea. He might not be able to come back.

He quickly changed the topic, "Mr. Shi, does he have any research on the moon?"

He was testing, if this person was an astronomy fan, it would be simple.

"Of course." Shi Zhengran smiled and stroked his beard, "I observed the waxing and waning of the moon and discovered the pattern."

Then came another terminology.

Han Ji and He Lianrong became fools again, but they saw that the Duke of Qin was listening with great interest, and they thought, could the Duke of Qin really know about astronomy?

In this era, when people were praised for being knowledgeable, the most commonly used words were astronomy and geography, indicating that they knew everything.

But it is so difficult to achieve this. Astronomy is so vague that it is difficult to learn geography by yourself. Maps in this era are strategic materials and are not allowed to be owned by private individuals.

Then you can only use your feet to measure.

Your Majesty, it seems that you haven’t traveled much!

Yang Xuan and Shi Zhengran chatted for a long time and suddenly asked: "Has Mr. Shi ever studied why the moon shines?"

Shi Zhengran said: "Just like the sun, the moon will naturally shine."

In this era, many natural phenomena do not need explanation, just one sentence: it is natural.

The sun shines because of nuclear fusion!

Yang Xuan said: "Didn't Mr. Shi notice? The sun is scorching hot, but the moonlight is cold."

"The sun is yang and the moon is yin."

"The sun rises and sets, and the sun sets. It does not disappear, but shines on the other side of the big ball under our feet. Please look at it, Mr. Shi."

The sunlight shines under the steps and reflects in, illuminating half of the room.

"Huh?" Shi Zhengran was puzzled.

"This is the reflection of the sun shining on the steps. What about when the sun shines on the moon?"

Yang Xuan stood up and said, "Goodbye."

He went over to hold A Liang and left immediately.

Behind him, Shi Zhengran stood up and wanted to send him off, but when his body was covered by the reflected light, he couldn't help but reach out to touch her.

Yang Xuan returned to the Jiedushi Mansion.

"Didn't it work?" Luo Cai asked.

Yang Xuan said: "Look!"

Liu Qing said: "The current situation in the world is chaotic, so those great talents will cherish their feathers and wait and see before making plans. Otherwise, find an emergency first, and then hire another one after the general situation is settled."

Luo Cai said: "If I were not so busy, I could still teach Da Langjun."

Yang Xuan said: "Let's take a look again."

This time he had finally figured out the thoughts of those great talents, who were all stubborn people who cherished feathers.

Yang Xuan then went home.

Liu Qing said: "Shi Zhengran is a rare talent in Northern Xinjiang. Not only his literary talent, but also his astronomy and geography are unparalleled in Northern Xinjiang. In addition, he also knows the calendar, which is rare.

It’s a pity that we didn’t ask for help.”

The Duke of Qin invited Shi Zhengran to come out for the little Duke but failed!

As soon as Yang Xuan left the east side of the city, the bad guys spread the news throughout the city.

Cao Bo smiled and said: "I'm just saying, who would take the risk to come out of the mountain at this time? In this case, I still have a chance."

Shi family.

"You can see clearly even where the sun doesn't shine. This is reflection. What if it shines on the moon? How wonderful!"

Shi Zhengran sat cross-legged in the reflected sunlight, his family members lined up outside the door, worried that he would twitch again.

Every once in a while, when Shi Zhengran's research reaches a bottleneck or finds a new goal, he always goes crazy.

"Wonderful!"

Shi Zhengran raised his head and said ecstatically: "Where is the Duke?"

The old wife said: "Didn't he leave?"

"What?" Shi Zhengran stood up suddenly, "Who let the Duke leave?"

"Isn't it you?" The old wife sighed, "You're crazy again, get ready!"

The whole family nodded in unison.

call out!

Before he finished speaking, Shi Zhengran disappeared.

The great talent of Northern Xinjiang, Shi Zhengran, went crazy.

He ran out of his house disheveled.

"Is that Mr. Shi?"

Pedestrians on the street couldn't help but be stunned when they saw Shi Zhengran running wildly.

Shi Zhengran ran all the way to the outside of Jiedushi's mansion and rushed in. After being held up by two sergeants, he shouted: "I want to see the Duke, I want to see the Duke!"

"Hold on!" Just when the two sergeants were about to teach the old guy a lesson, Liu Qing, who happened to come out, stopped them.

"You are..." Liu Qing looked carefully. "Shi Gong?"

Yang Xuan discussed with Zhou Ning at home the arrangements for A Liang's follow-up education.

"What I mean about medical skills depends on A Liang's interest. If he is interested, you can teach him more. If he is not interested, you can teach him some common sense and life-saving things!"

Yang Xuan didn't want his son to become a so-called all-rounder or erudite. The price was too high and unnecessary.

"Medical skills are not that important. They can be taught at any time, but enlightenment is more important. If you don't get a famous teacher, it will ruin A Liang's life." Zhou Ning was a little worried, "I have also heard of Shi Zhengran, although he is a bit stubborn.

But he is a man of great talent and good character, so it’s a pity.”

"Let's see, maybe he will come." Yang Xuan thought to himself that if Shi Zhengran truly loved Tianwen, there would be no chance of this happening.

"You don't know the thoughts of such a talented person. Since he refused, he will definitely not come again." Zhou Ning said with a smile: "Otherwise, it will be a slap in the face."

Great talents love face the most!

Hua Hong came in. "My lord, a man has been sent from the Jiedu Envoy's Mansion, saying he wants to enlighten Da Langjun."

Zhou Ning asked, "Who?"

"Shi Zhengran."
