The Han dynasty of the Central Plains almost had an almost crazy attachment to the Great Wall, like the Egyptians worshipped the pyramids, and the Mayans were crazy about the temples.

This is an attachment that is integrated into the bloodline, and it has not changed since the Qin Dynasty.

At the beginning, Zhao Zhen simply thought that the Great Wall was a passive defense, and after having the Great Wall, he could sit back and relax, and he could rely on man-made natural dangers to attack the attacking enemy.

But Pang Ji told him that this was not the case, that everything was not what it seemed, that the Great Wall was not just a high wall, not just a place of defense.

Today's feast is not only full of classics Yang Xiu, but also Pang Ji, who is familiar with political affairs, he sits quietly in the master's position, and behind him is the portrait of Confucius, the old man sits quietly, as if he should have been sitting there, Zhao Zhen feels that this Confucian natural temperament.

This Confucian appearance has to be convincing, isn't it?

After taking a sip of tea to moisten his throat, Pang Ji slightly tidied up his sleeves that were not messy and said, "Why is Your Majesty unwilling to build the Great Wall?" This is a matter of benefiting the country, the Qin Emperor and the Han Dynasty have all stopped, and the Great Song Dynasty has seized Yanyun in the north to seize the vital land, there is the danger of the Great Wall, and the enemy who can resist the attack. ”

Zhao Zhen frowned, he didn't know why when he raised his opposition to the construction of the Great Wall, why the civil and military officials in the court vigorously opposed it, and the military generals' opposition was understandable, because this was their defensive offensive, which could make the soldiers on the border more safe and comfortable.

But the opposition of the civil officials made him a little confused, didn't the civil officials resist this kind of bad government? The construction of the Great Wall will not have a good reputation, Qin Shi Huang's head has a connection with the Great Wall, and the Great Wall of the Han Dynasty is the ironclad evidence of the tyranny of Emperor Wu of the Han Dynasty.

Of course, it is clear that some of them were slandered by later generations for some purpose, but it is undeniable that his prestige was affected.

Zhao Zhen thought about it and replied to Pang Ji in the simplest and easiest words to persuade Wenchen: "Because the Great Wall is hard and money, after my Great Song Dynasty recovered the northwest, the territory is vast, if the Great Wall is built, the cost is huge, and I am preparing to wave my troops to the Northern Expedition again, what is the point of building the Great Wall?" ”

Pang Ji and Yang Xiu glanced at each other, and the two sides showed mysterious smiles, which made Zhao Zhen inexplicable, Pang Ji finally said when Zhao Zhen was about to go berserk: "Your Majesty thinks that this Great Wall is only used for defense?" ”

Zhao Zhen said a little strangely: "Since ancient times, it has been to build a city to defend against the enemy, and the construction of the Great Wall is just to frame the Great Song Dynasty in a city, relying on the advantages of the high wall to attack the enemy, what is the use of this?" ”

"This is the use of the pass, the Great Wall restricts not only the soldiers and horses, but also the common people and merchants...... What do you say, Your Majesty? ”

Zhao Zhen frowned and thought for a while before he suddenly realized, and the conclusion he came to made him dumbfounded, this ...... This is really incredible, it turns out that the role of the Great Wall is not only to defend against foreign enemies, but also to play the role of the country!

Suddenly, Zhao Zhen felt that he was impressed by the wisdom of the Chinese ancestors, how many years has this kind of reverse thinking deceived the grassland people? I'm afraid that when I knew that the Qing Dynasty ruled the Central Plains, I could understand the truth, right?

Not to mention the grassland people, even Zhao Zhen himself, a descendant of the world, was stunned by this conclusion, of course, maybe he himself did not study, and even carefully observed the majestic and immovable miracle that towered on the land of China.

The Great Wall not only plays this military role, but also a kind of blockade, an economic blockade! Zhao Zhen suddenly realized, this makes sense, no wonder the mountains and mountains, no wonder the Great Wall has been built on the Gobi, the horses can't go up at all, and the Gobi is difficult to hold if it is a large-scale breakthrough.

In that case, what is the significance of the Great Wall?

Pang Ji's words are like opening a window for Zhao Zhen, blockade, the blockade of the Great Wall sometimes exceeds its military role, it is undeniable that the military value of the Great Wall is immeasurable, but the economic role has been underestimated by successive dynasties.

Although the Great Song Dynasty did not have the Great Wall, it did not affect the study of the Great Wall, the Qin and Han dynasties had the Great Wall, and the Great Wall was strengthened in all dynasties, although the Great Wall was not overhauled in the Sui and Tang dynasties, but the strengthening of it never stopped.

The Great Wall of the Han Dynasty, which is nearly 10,000 kilometers long from the Dawan Ershi City in the west to the north bank of the Yalu River in the east, has been built quite perfectly, but the Great Song Dynasty cannot use it, because the Great Wall of the Han Dynasty is almost all in the territory of the Liao Dynasty, so the courtiers of the Great Song Dynasty proposed to build their own Great Wall.

Once the Great Wall was built, the trade between the Great Song Dynasty and the Liao Dynasty was completely settled by the Great Song Dynasty, and it can be said that since the day the Great Wall was completed, the merchants of the Great Song Dynasty entered and exited the Great Song Dynasty by the imperial emperor, and if the trade was to be closed, the easiest way was to prohibit the merchants from going to the Liao Dynasty.

This is a kind of complete prohibition without a trace of negotiation, the Great Wall not only blocked the merchants of the Liao Dynasty, but also made the merchants of the Great Song Dynasty unable to move forward, and could only trade through the passes opened by the imperial court, which was a kind of monopoly of convenience.

Of course, the role of the Great Wall is not only like this, it is a large and complex system, and when Di Qing arrived, Zhao Zhen knew that there was a certain agreement between the civil and military officials, and it was necessary to promote the construction of the Great Wall.

Zhao Zhen never denied its military value, he remembered that later generations had seen a documentary, eleven kilometers away, the time to transmit the news with the beacon tower was only a short seven minutes, and the car took nine minutes, and this was still in the case of the beacon tower after thousands of years of corrosion.

As long as a beacon tower at the border pass is lit, this long chain of information will not be broken, and it will spread all the way to the city of Beijing, much faster than the flying pigeon to pass on the book.

The Great Song Dynasty also has the strongest means of defense, and the role of the Great Wall has been the biggest obstacle to the nomads since ancient times, so what is the use of you having 100,000 iron horsemen?

What about under the endless city walls? Have the ability to ride a horse over? Not to mention the Great Wall, even the three-meter-high earthen wall can become a fatal obstacle for cavalry!

Seeing Di Qing coming, Pang Ji showed a long-lost smile, he had a very high impression of this privy envoy, Di Qing is not only a military general, but also has a unique Confucian demeanor.

Clearing his throat, Pang Ji said to Zhao Zhen: "Official, the old minister is not familiar with military affairs, but he knows that the construction of the Great Wall can be used to block transactions, and it can also be used to quickly spread the news and block the country, so it can be prevented!" General Di is well versed in military affairs, and His Majesty is the holy monarch of the imperial expedition, and the military ministers are not good at getting axes. ”

Zhao Zhen smiled and pointed at Pang Ji, and then pointed at Di Qing: "I'm afraid that the two of you have already discussed, and today's banquet has also become your lobbyist, and the construction of the Great Wall is very troublesome, and the court will discuss it again tomorrow." ”

Pang Ji and Di Qing breathed a long sigh of relief, Zhao Zhen could even hear the sound in Di Qing's throat, these two people were too nervous, Di Qing was understandably nervous, why was Pang Ji so nervous............
