The Great Wall built by ancient Chinese people has been criticized by many people in later generations. The Great Wall of Qin is regarded as a symbol of tyranny. In modern times, the Great Wall, which is a world miracle, represents the conservative character of the Chinese in the eyes of many people.

Chinese people like to surround themselves with a wall, and many people say this.

After on-site investigation of the border between Qin and the Huns, Meng Tian truly understood the words of a philosopher: Existence is reasonable.

The ancient Chinese built the Great Wall on the northern border, which had nothing to do with tyranny and character, but under the conditions at that time, they adopted the most economical choice.

China is facing pressure from the invasion of the Hu people in the north, which is far more severe than other parts of the world. The Scandinavia in northern Europe produced vikings, but soon declined.

But ancient China was different. The grasslands in the north ended in Siberia tundra, west to the inland Central Asia, east to the large and small Xing'an Mountains in the northeast. The Xiongnu were Xianbei people, the Xianbei people were Turks, the Turks were Khitans, the Jurchens, and then the Mongolians, Pigtail Tartars.

To deal with these nomadic peoples in the north, they used military means and spent huge amounts of manpower, material resources and financial resources to eliminate one, but as a result, another emerged like a field mouse. It was difficult for all dynasties to maintain strong military capabilities for a long time since their founding.

Even with strong force, the long border in the north, without the Great Wall shielding, no matter how many troops are, they cannot cover everything. When the Americans spend a lot of effort to build the American-Mexico wall, they should be able to experience the helplessness of the ancient Chinese.

"This is the original design of the Great Wall. Will it still be repaired as it is this time?"

Qu Ji found the album of the Great Wall from the county magistrate's library. In his opinion, the project volume was already quite large just to repair the damaged Great Wall.

"The city walls lingering on the mountain can be built as it is, but the gates of the Great Wall need to be redesigned."

Meng Tian decided to improve the original Great Wall system.

The original Great Wall defense system was too single, and it was difficult to achieve the purpose of defending against the Huns when the Huns army was approaching.

"The gate of the Great Wall needs to be raised and changed to a bastion structure, with a place for a scattered machine reserved on it, and a shooting hole for a crossbow cart is installed. If the Huns attack again, I will make the Huns run wild!"

Meng Tian dipped in ink and outlined his idea on silk cloth: "On the pass, facing the grassland, two frontier fortresses are built to form a corner to support each other."

The best defense is always an offense, which will lead the war to the land of the Huns.

"Within the pass, choose a place with a steep terrain, and then set up a second line of defense, and build Tunbao in various villages......"

According to Meng Tian's plan, three lines of defense were blocking the Huns, and even if the Huns' Khan raised troops to attack, they would be as solid as a rock.

"Can the people of Shangjun cope with such a heavy project?"

Qu Ji wiped the sweat from his forehead and muttered in his heart that the more he could fight, the less kind he was. Otherwise, why would he say that kindness would not command the army?

"Not only the people of Shangjun, but also the soldiers under my command, will participate in the construction of the Great Wall!"

He lifted his sword to serve as a soldier, and putting down his sword to be a first-class construction worker. Meng Tian had such confidence in his soldiers. When he was stationed in Nanyang, the Nanyang Corps built a camp and helped Shi Lu build a water conservancy project, and accumulated rich experience.

"The construction of the Great Wall will be unified and dispatched by Feng Wuzhe, the general of the engineering battalion of our army. I hope the county magistrate will mobilize the county craftsmen to participate, improve tools, and save manpower with good tools."

Meng Tian put down his pen and comforted Qu Ji with a smile: "Technology is productivity. As long as you have advanced production tools, you can easily build the Great Wall!"

The next day, Feng Wuze, the commander-in-chief of the Great Wall Engineering Command, set up a large wooden sign at the camp gate of the engineering camp, which read: Tools liberate human resources.

The weather gradually became colder and the autumn harvest had been completed. All the soldiers and civilians of Shangjun joined the Great Wall Construction Corps in full swing.

Unlike previous years' corvee labor, this year's corvee seems to have a lot of joy.

The art troupe organized often cheers and shouts at various construction sites. When they are resting at night, there are special repertoires and singing and dancing, which makes people forget their fatigue without realizing it.

The Nanyang Corps led by Meng Tian has now officially begun to transform into the Great Wall Garrison Corps and takes turns to the Great Wall construction site.

As the main general, Meng Tian also went to the construction site in person to participate in the construction of a section of the city wall. Until many years later, the section of the city wall built by Meng Tian was still in the hearts of the military and civilians of Shangjun, and the reputation of "General Wall" was circulated.

"General, I didn't expect that this small pulley and this inconspicuous lever can save so much manpower!"

The craftsman saw a lot of supplies, and easily transported them to the top of the mountain under the pulley, and was so excited that he danced with joy.

Only when tools free human powers, Sen truly understood Meng Tian’s words now.

Meng Tian gave Sen a blank look, as if he thought he was making a fuss. Aristotle in the West once said boldly, giving him a fulcrum, and he could leverage the earth. The ancient Chinese, especially the Qin people, did not lack engineering wisdom, but few people left shocking works.

The Qin people did not lack experience or technology, but they just lacked the discussion of theory. The book Mozi in the Warring States Period had records of simple geometry and physics, but after Mozi, the people of the Mo family seemed to have no breakthroughs.

Do I want to write a book on mathematics and will it win Mengzi's reputation? Thinking about two thousand years later, when the math teacher was in class, a serious introduction to the book "Mengzi" from the pre-Qin period, Meng Tian couldn't help but feel that it would be very interesting.

"Sen, you must keep this truth in mind. Advanced technology produces advanced tools. Advanced tools are an important magic weapon for our army to be invincible!"

When Meng Tian thought of the scimitar in Nu Chi's hand, he felt more and more urgently the development of high-quality iron weapons.

"This time, there was a scimitar used by the Huns' leaders, which was forged with iron. It was extremely sharp. If the Huns used it on a large scale, our army would suffer a loss!"

The Hanquan sword that had been following Meng Tian for many years, even had rifts on the sword, so Meng Tian couldn't help but not be alert.

"Thanks to the general who killed many Huns this time and seized several scimitars, which are similar to the iron swords I have seen before. Don't worry, General, Sen will definitely create an iron sword that is sharper than the Huns' scimitars!"

Sen patted his chest and sweared to the death. He had almost studied the Huns' scimitar thoroughly. As long as he built the workshop, he could start building it.

"There is no need to create an iron sword, create such a knife for me."

Meng Tian shook his head and denied Sen's proposal to build an iron sword. Instead, he squatted down and drew a prop on the fragrant grass. It was longer than the Huns' scimitar, and a circle was inlaid at the end of the hilt, which was the most famous ring-headed sword in the Han Dynasty.

If you want to do a good job, you must first sharpen your weapons. This is especially true in the military. Sometimes, the invention of a new weapon will often change the strategy and tactics of war, and even the situation of war.

"A knife is the most suitable weapon for cavalry to chop on horseback!"
