PS: I originally wanted to write about the scene of the war in detail, but then I looked at the chapter, and suddenly found that the mythical world had written nearly 200,000 words, so I quickly brushed it off.

The emergency movement of hundreds of thousands of troops is a huge undertaking both in modern and ancient times.

Since the end of the last discussion, it took the army to move for nearly a month before it was urgently transferred from the south and north of Great Qin to the frontier.

This is still thanks to Qin's military mobilization ability and the straight road built by Ying Zheng, otherwise I don't know how long it will take.

When modern people mention the Great Wall, they will inevitably think of Qin Shi Huang's construction of the Great Wall, and even the story of Meng Jiangnu crying on the Great Wall, which is actually some smearing of Yingzheng in later generations.

Ying Zheng did build the Great Wall, but it was not built out of thin air, it just connected all the Great Walls of the original six countries together.

In the era of the Seven Heroes of the Warring States, some countries close to the Xiongnu also built a section of the Great Wall, but it was intermittent due to the large number of countries, and after the unification of the six countries, these Great Walls were all connected together.

And the Great Wall is not used for combat, it is not like in film and television dramas, standing on the Great Wall and fighting to the death with the other party, on the contrary, its role is only for early warning.

At that time, Chen Feng, who heard the role of the Great Wall for the first time, was very surprised by this, and later checked some information to understand the original role of the Great Wall.

"General Meng, you have done a great thing that will go down in the ages."

Chen Feng stood on a section of the Great Wall, looking at the grassland in the distance, and couldn't help but feel a little emotional.

The construction of the Great Wall is indeed a matter of serious casualties, but the role of the Great Wall is especially important for the feudal dynasties that have lasted for more than 2,000 years.

The Great Wall directly separated the two ethnic groups, which in later generations would be unconscionable to experts and scholars, because they would say that it blocked the integration of ethnic groups.

But for the ancient Chinese, the Great Wall was a protective checkpoint, protecting the farmers and herdsmen Chinese from being harassed by nomads.

The nomads of the north were best at cavalry combat, and cavalry was synonymous with rapid mobility in ancient times.

The function of the Great Wall is to delay the attack of the northern nomads, and when the nomads cross the Great Wall, the beacon tower will release the news of the invasion through the beacon, so as to prepare the army to defend against the enemy.

"It's certain that you will leave a name for eternity, but I'm afraid that what you will leave behind is just some notoriety."

Meng Tian shook his head with a wry smile, where was the Great Wall so easy to build.

Others don't know that as one of the main persons in charge of the Great Wall, the death list is stacked on his desk.

The name of three or two words represents a family, how many people are there in the entire Great Qin, and when they built a Great Wall, more than 100,000 people were killed and injured.

Chen Feng also smiled bitterly when he heard Meng Tian's words, although Meng Tian's name was not linked to the Great Wall, and even ordinary people's understanding of Meng Tian came from some film and television dramas.

"The harm is in the contemporary, and the merit is in the future"!

Chen Feng thought about it, and could only say silently, the construction of the Great Wall did kill and injure many people, but his appearance allowed more people in later generations to avoid the invasion of northern nomads.

Stretched out his hand and patted the city wall in front of him, because this place is very flat, the materials used are also some marble, unlike other places, most of them are made of mud.

Looking at the city wall in front of him, Chen Feng suddenly thought of the Beijing-Hangzhou Grand Canal built by Emperor Yang of Sui in later generations, its role seems to be not much different from the Great Wall, and countless people have also died, but it has been used by future generations for thousands of years.

Although the two Central Plains dynasties are separated by thousands of years, they all do the same thing, leaving great achievements, but they also died twice, I really don't know whether it is a coincidence or a definition in the dark.

"But it's a pity, General Meng. After this battle, the northern Xiongnu will inevitably collapse, and the Great Qin will no longer have any worries in the north, and the role of the Great Wall will probably come to an end again."

Seeing that the atmosphere was a little solemn, Chen Feng looked at Meng Tian with a smile on his face and said with a smile.

Chen Feng didn't know whether the Great Wall would play a role in the future, but Chen Feng had already done what Great Qin would do once the Xiongnu were defeated.

That is to build a city on the grassland, and eventually there will be a city like Kannai. It is definitely no longer like the later dynasties, and it has returned to Kannai.

That will only leave a blank area, and after a few decades or hundreds of years, there will be a new group of nomads, re-occupying the grassland, and continuing to threaten the Central Plains Dynasty, and what I have to do is to completely eradicate this threat.

"Alas, it's just that at this time, the words of the wartime together suffered, and it was still the people of my Great Qin, and it was the officers and soldiers who were killed and injured or my Great Qin.

Now, after decades of conquest, my Great Qin has long been exhausted, and I really don't understand why my father wants to attack the Xiongnu in the north."

Chen Feng wanted to pick the atmosphere, but someone poured cold water on Chen Feng, this person was none other than Fusu, who was sent by Yingzheng to the army to be the supervisor of the army.

When Chen Feng, who saw Fusu for the first time, he was also a little amazed, and even a little ashamed of himself, saying that he could not be compared with recovery.

is gentle and elegant, talks generously, and has insight and eyesight, but this character makes Chen Feng a little out of place.

Ying Zheng's character is outgoing, while Fusu's character is introverted, which is completely the character of two people, which makes Chen Feng a little doubtful whether Fusu is Ying Zheng's son. Especially the looks of the two, there are really some big differences.

"Childe, you're only half right.

In the short term, Daqin is naturally the same as what Gongzi said, but if you look at it in the long run, the benefits outweigh the disadvantages."

Because he already regarded Fusu as a dead man, Chen Feng's tone was naturally not too good, and he answered bluntly.

"I naturally know this, but the fact that Great Qin can have the world today is the result of the unremitting efforts of the kings and ministers of the court, and it is the pursuit of countless old Qin people.

Now that Great Qin is unified, the world should let the Qin people who have struggled for hundreds of years take a break, instead of continuing this struggle and letting countless Qin people continue to dedicate."

Fusu took a deep breath, and there was a sneer in his words.

As the eldest son of the emperor, he naturally knew that the plan to attack the Xiongnu in the north this time was bewitched by the person in front of him.

What's more, I don't know why this person always looks at himself unpleasantly, and he is provoking his relationship with General Meng in and out of his words.

For a while, Chen Feng and Fusu were a little-for-tat, Meng Tian stood in the middle, and some were not people inside and out.

"General Meng Yi, you said that I was right or wrong to attack the Xiongnu in the north, remember to speak from a historical point of view."

Chen Feng is an ordinary little person, and his biggest status is that of today's national teacher, and he is also the kind of person who doesn't ask about the world.

Now arguing with Fusu, for a while, there was something that couldn't say Fusu, Chen Feng, who was angry, was itching in his heart, turned his head, and saw Yi Xiaochuan standing behind Fusu, and directly pulled Yi Xiaochuan over.

"For Daqin, it is ...... to recuperate at this time."

Yi Xiaochuan also didn't have a good impression of Chen Feng, so naturally he wouldn't follow Chen Feng's words, but before Yi Xiaochuan's words were finished, he was directly interrupted by Chen Feng.

"I said from a historical point of view, you don't know, or I'll give you a reminder, the siege of Baiden."
