Datang: Inheriting the system legacy at the beginning

Li Yin slowly and firmly stated Yang Guang's achievements word by word.

Li Shimin's complexion also became more and more serious.

Changsun Wuji took a look, and the secret path was not good!

Although Li Er in front of him is His Majesty the Emperor of the Tang Dynasty, he is also his brother-in-law who grew up with him.

As for the pride of the emperor, it can be said that no one present understood him.

Just looking at his brother-in-law's face, he knew that he might really be questioned.

But Li Er was out of his own pride, and it was not easy to refute, so it would really appear that the emperor was too stingy.

So Changsun Wuji rolled his eyes, and immediately found the loophole in Li Yin's words, and asked:

"Your Highness Sixth, you say that Yang Guang is the emperor who completed the unification of the north and south of China, so where do you put the first emperor?"

As soon as these words came out, no matter whether they were civil servants, generals, or even princes and noble sons, everyone in the field seemed to have caught something.

"Hey! Little bug, I think your father is right. The First Emperor is the first emperor in China to unify the north and the south!"

Chang Sun Chong: "Get out! You are the little bug."

"Haha! Little six, I'm afraid I'm going to be questioned by the elder grandson!"

"Yo, I didn't expect to be robbed by the elder grandson!"

"That's right! How can he, Yang Guang, be able to unify China?"

……

Seeing that everyone was questioning, Li Yin couldn't help laughing!

His laughter grew louder and louder.

It wasn't until everyone stopped discussing under his laughter that he continued:
"Tomorrow of my Great Tang, my Lord of the Humerus, and even His Majesty the Emperor of my Great Tang are present here! I just want to ask you, do you know what the true meaning of Great Unification is?"

All of a sudden, everyone in the classroom became contemplative.

Li Shimin frowned even more.

According to the theory of great unification proposed by Sima Qian, it should first be the great unification of the territory.

Then there is the great unification above the people's thinking, and finally the great unification of the nation.

After a while, he felt that he understood, and said directly:
"Are you talking about the great unity of the nation? Although the Sui Dynasty managed to recognize the Yanhuang nation together with the Hu and Han, this is not due to him alone, Yang Guang!"

"Yes! The great unification of the nation is the result of the joint efforts of all the emperors of the past dynasties. Why did you put it on your grandfather?" Changsun Wuji's eyes lit up, and he questioned directly.

Li Ji also frowned, thought for a moment and said:
"The unification of the nation was indeed completed in the Sui Dynasty, but this should be the centripetal force condensed by the unified dynasties of the past dynasties. The Sixth Highness, you will be in trouble if you count it on the head of Emperor Sui Yang!"

Li Yin twitched the corner of his mouth lightly, sneered and said:

"Is this the unification that you, the top leaders of the Tang Dynasty, understand?"

"If I'm talking about Sima Qian's theory of great unification, then the system and framework of great unification were basically completed during the period of Emperor Wu of the Han Dynasty. All the kings of later generations only need to implement this system and framework, and they will be able to do it. to the true sense of national unity."

Then he looked at Li Er's face and found that he did not continue to run away, so he continued to stretch out a finger and said:
"Great unification in the true sense is actually regional unification!"

"This is the biggest problem left to future generations by the Qin Emperor and Han Wu. Think about it, since the first emperor unified the Central Plains, have the regional customs, cultural differences, and geographical natural dangers on the land of China caused our entire country to fall into a long-term crisis? In the situation where the north and the south are separated and the east and the west are facing each other."

"It is also the biggest problem on the road to unification that led to the 360-year-long division of the Wei, Jin, Southern and Northern Dynasties!"

Everyone also fell into silence one after another. They can become the top figures of Datang's pyramid, who can be an idiot?
For a moment, the first person to speak was Cheng Yaojin, whom everyone thought was a big boss.

"Whoo~"

"It's exactly as Little Six said! The natural barrier of the Yangtze River is a natural barrier that separates the land of China!"

Li Jing, who has led the army to fight on all sides for a long time, also said with deep emotion:
"Both the north and the south are huge in terms of customs and culture. Only when the people of the two sides agree with each other can they win the hearts of the people."

"At the end of the Eastern Han Dynasty, Cao Cao's military power was clearly enough to destroy Sun and Liu. Why was it so late to complete the unification? Isn't it because of the natural dangers of geography?"

Changsun Wuji also had to admit at this time that he couldn't refute what Li Yin said.

However, Fang Xuanling looked at Li Yin and said doubtfully:

"Could it be that the regional unification you mentioned, the Sixth Highness, means that the forces of all parties can no longer rely on natural dangers to separate one side?"

Li Yin chuckled, glanced at Li Shimin with a deep expression again, and then continued:
"That's right! Regional unification is not about establishing a unified dynasty on our land of China. It's about breaking down the natural barriers between the north and the south, and breaking through the regional barriers.

Today Xiaoliuzi dares to ask you gentlemen, since my grandfather built the Grand Canal, is there anyone who can form a long-term military separatist force in the south or north?
Of course, the role of the Grand Canal is not limited only, it can enable soldiers to quickly pass through natural barriers and reach rebel areas to suppress them.

It can also connect the north and the south, and the food in the south can be supported to the north as quickly as possible, so that the north can survive the disaster year smoothly, and the peasants will not revolt due to the disaster.

What's more, it can also enable the north and the south to communicate in business, trade and culture.

As long as there is profit-driven, the cultures of the North and the South will recognize each other, and as the gap between the cultures and customs of the two sides becomes smaller and smaller, the country will be able to win the hearts of the people.

It is also possible that no one in the Central Plains Dynasty after the Sui Dynasty could rule by rowing the river. "

wow~
As soon as these words came out, all the students present opened their mouths wide and looked at the confident Li Yin.

As if looking up at the gods.

Why are you also entering the Hongwen Museum for the first time to study? Why are you so handsome, the sixth prince?
You gave us a way out!

Not only did he dare to confront Mrs. Xu on the spot, but he was also able to speak so that His Majesty and many uncles were speechless.

It's just that they didn't realize the seriousness of the matter at this time.

All the ministers present were also shocked by Li Yin's explanation.

They are all the founding heroes of the Tang Dynasty, and even these civil servants have followed Li Shimin to conquer the land of China for a long time.

They have personal experience of what Li Yin said, and they are also the people who have the most say in the entire Tang Dynasty about the benefits of the Grand Canal.

While admiring Li Yin, a 7-year-old kid, for his insights, they all focused their attention on their own son.

It was also the first time they entered the Hongwen Museum, and most of them were much older than Li Yin.

But why can't my own cub have this understanding?
If it was my son who was talking here today, how much face would I have to earn in front of these old brothers.

Well now, all the face has been earned by His Majesty!

No!

When I go home tonight, I definitely have to clean up my son, otherwise how can I have the face to look up in front of my old brother from now on!
