The short video shows the ancient times, and the emperors cried with envy!

Chapter 451 Geographical Determinism! Agricultural Civilization Line?! The Economic Value of the Great Wall Stunned the Ancients!

"Why?"

In Huisong, Princess Roufu looked at her father innocently.

Zhao Ji closed his eyes in pain. The Great Wall! The Great Wall! If the Great Wall was there, his family would not be in the Five Kingdoms City.

"Because the Great Wall defense line blocked almost all the small groups of Huns!"

Dahan, Mobei grassland, Huo Qubing's eyes sparkled, he looked at the distant sky and shouted loudly.

"My men, the Great Wall is behind us, we will fight to the death!"

"Fight to the death and never retreat!"

Thousands of soldiers behind him shouted along with him, because they saw Wolf Mountain!

At the end of the Northern Dynasty, the handsome Gao Huan, wearing a scarlet robe, stood in the ranks of Erzhu Rong's army, watching his officers and soldiers slaughter the brothers of the Six Garrisons, and muttered:

"How can the Great Wall be useless? It's a natural barrier!"

If there had not been the Great Wall pass blocking their large cavalry force, they would have long since fled into the deep mountains and forests of the Taihang Mountains and headed south all the way to Luoyang.

As if to echo their words, a tragic scene was played on the video above the sky.

[No matter when, the nomadic tribes in the north always avoid large-scale combat, because they are best at long-distance raids and wild wolf tactics. ]

[It is better to tire out the enemy and take your time to defeat them than to confront the tin-canned soldiers of the South head-on.]

[But the Great Wall changed all that! This fortress defense line standing on the northern border has the most advanced communication and mobilization capabilities. ]

[Five out of ten small-scale invasions by the northern grassland peoples were discovered in advance, and three of them failed.]

[Perhaps there were two more times when they succeeded by chance, but when they finished the looting and wanted to return by the same route, they found that the pass was blocked and a large number of troops were waiting for them to fall into the trap.]

[It is precisely because of the existence of the Great Wall that the nomadic peoples were forced to form a large army and were able to go south to herd horses! ]

[And this possibility may not happen once in a hundred years! ]

"How hateful! The Great Wall has been played around by these southern barbarians. If Li Keyong hadn't had the support of the Cloud Great Wall, it would have been hard to say who would have won!"

In Khitan Kingdom, Yelu Abaoji slapped his thigh hard, feeling as if he was empathizing with the video.

Of course, every powerful ruler on the grassland has a fear shadow dominated by the Great Wall, such as the Genghis Khan who is peeking at the screen.

Temujin, who had not spoken for a long time, could no longer hold back and said sadly:
"It's hateful. The southerners' walls are indeed strong. If it weren't for Mu Huali in the battle of Yehu Ridge, I'm afraid we would have turned into bones in the Onon River by now!"

In the Battle of Yehuling, the Jin Kingdom had the Great Wall at its back and sent out its best troops, including the Iron Pagoda that once dominated the world. In that battle, the Mongols lost half of their loved ones.

"Therefore, we must not allow them the opportunity to build city walls on the Han people's territory!"

Temujin looked at the many heroes in the big tent, many of whom were Han Chinese, and made a secret decision in his heart.

Needless to say, the psychological activities of these grassland heroes were reflected in the video showing the great role of the Great Wall defense line.

His Majesty the First Emperor of China, the patent owner of the Great Wall and the builder of the wonder, was even more excited.

"Where is Meng Tian?"

"Chen is here!"

Meng Tian stood up and bowed to Ying Zheng's gaze.

"Since the heavens say that my tyrannical Qin built the Great Wall, stretching thousands of miles and setting a precedent for all ages, I would like to ask you, do you dare to go north for me and build this Great Wall?"

"But Your Majesty, didn't it say in the sky that the Great Wall would be a waste of manpower and even endanger the foundation of our Great Qin?"

Upon hearing that Ying Zheng was still going to build the Great Wall, Li Si quickly stepped forward and asked.

"Since it is necessary, why not repair it? The Huns in the north are eyeing us covetously, how can we stop them just because of one sentence? Besides, the merits and demerits of my actions will be judged by future generations!"

Ying Zheng waved his sleeves and said no more. Li Si and Meng Tian looked at each other and nodded in agreement.

Above the sky, the camera suddenly zoomed up to the sky, overlooking the entire Chinese land. Along with the magnificent scene, a voice-over suddenly sounded:

[As for the second question, a thousand years can be a cause for regret for the change of dynasties, and a hundred years can be a cause for the change of seasons. It is people who determine whether the passes and the Great Wall can play their role.]

[Emperor Wu of Han pursued the enemy to the north and, based on the Great Wall of Qin, achieved the achievement of engraving the Yanran Stone; Zhu Di of the Ming Dynasty also made five expeditions to the northern desert and destroyed the Mongolian tribes. ]

[Also during the Han Dynasty, countless Han generals colluded with the Xiongnu to plunder the Central Plains. During the Chenghua period of the Ming Dynasty, the Mongols once again moved south and burned the Great Wall. Therefore, the city wall ultimately relies on people to protect it.]

[Reality is a symbiotic whole, just as no one would believe that Wu Sangui, who guarded the natural barrier of Shanhaiguan, would betray the Ming Dynasty and surrender to the Qing Dynasty.]

【It is so irresponsible to attribute all the problems to a wall without any warmth.】

The words in the video made everyone in front of the screen lower their heads. Zhu Yuanzhang, who was high-spirited and confident before, was now a little hesitant.

"Sister, do you think that if we don't build the Great Wall and rely solely on our sons and the garrison soldiers, can we safely protect the people of the North? If we can't stop them, then wouldn't we be sinners?"

"Zhongba, no matter what you do, we support you!"

Seeing the confusion and embarrassment in her husband's heart, Queen Ma supported him as always, held his hand and whispered.

"But who is Wu Sangui mentioned by that voice just now? How dare he betray our Ming Dynasty?"

Zhu Yuanzhang quickly calmed down and focused his attention on Wu Sangui, who had just spoken in the off-screen voice.

"Maybe it will be hundreds of years later? There is no such person among the generals in the court, and the current commander of Shanhaiguan is still under the command of General Lan Yu."

Li Shanchang replied quickly.

Not only Zhu Yuanzhang was investigating, but Zhu Di, the fourth eldest son of the Ming Dynasty in another time and space, was also furious.

Before he even moved the capital to Dadu, he learned that a future defender of Shanhaiguan had rebelled?
Where is Shanhaiguan? It’s right at my doorstep!

"It's really a rebellion! Dad, the two pacification offices of the Jinyiwei are ready. As long as you give the order, all those with the surname Wu in the army will die!"

At this moment, Zhu Gaosui was quite active. He was holding the Yanlin knife and shouting at Zhu Di.

"Get lost! You ignorant fellow, am I the cruel one? Just go down and investigate secretly, it's not worth killing them all."

Zhu Di put his hands on his hips, kicked Zhu Gaosui, and spoke unhappily.

"Yes, sir!" A cruel smile flashed across Zhu Gaosui's face. Anyone who dared to touch his Zhu family's kingdom would die!

As luck would have it, an emperor who had been peeping at the screen for a long time was staring with wide eyes at this moment, and asked the old eunuch beside him in disbelief:
"Wang Banban, Wu Sangui, do you know who he is?"

"Your Majesty, he should be a member of the Guanning Army. I have the impression that he is a relative of my ancestors!"

"Great! Zu Dashou's surrender once is not enough, he really has the will to destroy the Ming Dynasty!"

The young Emperor Chongzhen, with gray hair on his temples, slammed the table heavily. His eyes were red as he looked at the sky through the dome of the hall that had been in disrepair for a long time.

"Your Majesty, I will order Sun Chuanting and Hong Chengchou to bring you the head of Wu Sangui!" Wang Chengen shuddered and spoke quickly.

"No rush. Killing Yuan Chonghuan has already shocked the government and the public. There is no rush now."

Emperor Chongzhen sat steadily on the throne, holding a wooden ball in his hand, and looked up mysteriously. With the help of Tianmu Xianji, he no longer had any fear.

The video continues——

【Third, we need to know that building the Great Wall was indeed a tough job. It was not just a matter of the government spending money and labor and the common people enduring hardships. It was a project that had to be done.】

[Let me give you a detailed example. During the Chenghua period of the Ming Dynasty, the Oirat invaded and the nine frontiers were in danger. The Chenghua Emperor wanted to attack from the north, but the then Minister of War made a calculation for him.]

[If we were to attack, the mobilization of the army plus the loss of food would cost at least two million taels of silver, of which at most half would be lost! And the war would drag on, and it was unknown how long it would last.]

[But if we build the Great Wall in the damaged areas and open up trade, we only need a few hundred thousand taels to complete the task, and it will be done once and for all.]

[If it were given to you, what would you choose? ]

"Of course I will go out and destroy the northern barbarians. Why would I hesitate? I will not be at peace until the bandits are eliminated!"

Tang Dynasty, Cheng Yaojin still said stubbornly.

"Haha, Zhijie, don't be angry. You know that you should be patient when you need to be patient. Don't act on impulse until the last moment!"

Li Shimin listened to the examples in the video and had already made up his mind. Sometimes one does not fight not because one cannot win, but because the gain does not outweigh the loss.

He has done this kind of thing before. The Weishui Alliance with Jili Khan was even more humiliating. As long as you don't indulge in temporary peace, your enemies will eventually dance at your feet!
Ming Dynasty, Zhu Yuanzhang clapped his hands, although he didn’t know who this Emperor Chenghua was.

However, he was very happy that his descendants did not act on their own but were able to weigh the pros and cons.

"Haha, mutual trade? And they went south to plunder, giving them face?"

But on the other hand, Emperor Liu Che of the Han Dynasty had a different opinion. His ancestors had dealt with the Huns in this way before, and even adopted a strategy of marriage.

Now that we have finally waited for the Han Dynasty to become a powerful military, if you dare to stretch out your claws, I will chop off your claws!
"If the enemy can go there, I can go there too!"

Liu Che snorted. He didn't care about the Great Wall or not. As long as it was useful, he would use it. If it was useless, he would use tactics. Just like what the voice-over said -

It all depends on human effort!

[So, the role of the Great Wall is not as some people say, that it is the Maginot Line of the East, which is useless, but it is not an omnipotent firewall either.]

[Its role is nothing more than a bridgehead for countless Chinese dynasties and empires to march northwards for thousands of years.]

[If a dynasty does not even have the old land within the Great Wall, how can it have the face to call itself a unified dynasty? Then it will definitely lack a top-down spirit! ]

[This spirit of being invincible and defending the country is what makes the Great Wall so precious! ]

"Yes! The Great Wall is really something that makes people yearn for it!"

In the Song Dynasty, Zhao Kuangyin wielded the Panlong Stick in his hand. He was invincible on the battlefield when he was young, but he became more and more tired as he grew older and could no longer use this old friend.

The words just now from the sky gave him great encouragement, and he even felt a sense of grandeur that he had when he was young!

"Your Majesty! The Northern Han is provoking us again. Should we respond?"

Pan Mei, who was opposite him, had sweat on his forehead, not because he was sweating from the beating from Zhao Kuangyin, but because he was thinking about how to hold back.

"Northern Han? Haha, the Khitans can no longer sit still. I have made up my mind. When the rulers of Southern Han and Wuyue come to Dongjing City, I will lead the army in person!"

"understand!"

Pan Mei didn't know why Zhao Kuangyin, who always advocated taking things slowly when urgent, would make such a change, but for a warrior who wanted to achieve fame and fortune immediately, such a change was not bad!
"The Song Dynasty cannot become a dynasty that is not worthy of its name. Apart from anything else, the Sixteen Prefectures of Yanyun south of the Great Wall must be taken back!"

Zhao Kuangyin looked up and murmured in a voice that only he could hear.

Ming, Zhu Yuanzhang clapped his hands, and after listening to the words above the sky, he felt that his mind was suddenly enlightened, and his whole body was unblocked:

"That's right! The former Song Dynasty lost not only Yanyun but also its integrity because it lacked the Great Wall. Our Ming Dynasty cannot be like this!"

"Okay, okay, you are right. I don't know who the worried face was just now."

Queen Ma would not flatter him, so she spoke directly.

"Hahaha, sister, can't you just say something in agreement with me? The ministers are watching us."

Zhu Yuanzhang shook his head and pointed at the ministers below the stage.

"Don't! My eyes are blurry and I can't see clearly or hear clearly." Old man Song Lian was smart and turned his back.

Lan Yu and Li Wenzhong huddled together, arm in arm, while Li Shanchang, Liu Bowen and Hu Weiyong made a circle, the three of them leaning their heads against each other, not even looking at the emperor above them.

"Hahaha, you bunch of old guys!"

Zhu Yuanzhang laughed heartily, holding back the laughter in his throat, and said angrily: "Everyone will be fined one year's salary!"

Compared with the prosperous Ming Dynasty, the Sui Dynasty seemed a bit miserable.

There was no other reason, Yang Guang killed someone again.

The voice-over above the sky seemed to have pricked his sensitive nerves, and a minister stood up to persuade him not to march eastward to Goguryeo and to conserve the people's strength.

But he suddenly jumped up and chopped him through with a long sword. It was as if Yang Guang, the King of Jin who had personally led the southern expedition to the State of Chen, was possessed at this moment.

"Yu Wenzhi!" Yang Guang threw down the sword in his hand with a "clang", not caring about the blood on his body at all, and roared at the ministers.

"I'm here!" Yu Wenzhi walked out slowly at this moment and said with great discretion.

Yang Guang grabbed his hair, pointed his bloody sword at Yu Wenzhi and said:

"The Great Wall! The Great Wall! This damn curtain says that I am a tyrant because I have wasted money and manpower building the Great Wall, and it has brought disaster to the country and the people!
But when that damn Ming Emperor Chenghua built the Great Wall, was he weighing the pros and cons and doing it for the country and the people? Haha! In my opinion, it’s nothing more than that! "

"Your Majesty, what you said is absolutely right!" At this time, Yu Wenzhi did not want to anger Yang Guang, so he could only agree with him.

But it was obvious that the Emperor in front of him was not very satisfied.

"Forget it, forget it. There's nothing to say to a yes-man like you. Pass on my order! Since the sky says that repairing the Great Wall is a good idea, then continue to build it!"

"Your Majesty, should we continue the eastern expedition to Goguryeo?" Pei Ji stepped forward at this time and asked carefully.

"Go on! Of course I will!" Yang Guang showed a happy smile on his face and opened his arms, as if he wanted to grasp the entire Sui Dynasty in his hands:

"Not only the Great Wall, but also the Yongji Canal needs to be repaired, as well as Panyu City and Jinling City in Lingnan! I want them all!

Don’t those lowly people still have the energy to make trouble for me? I think they still have too little work to do! I pity them, and the government pays for them to live on!”

"This……"

All the ministers gasped and turned pale. It was all over. It seemed that the Sui Dynasty was doomed!
