In the evening, the sky is full of sunset, the air of Daxing City is full of cold, and the discussion of the Great Sui monarchs and ministers is still continuing, but it has come to the military aircraft room from the Liangyi Palace, the huge sand table clearly presents the mountains, fields, rivers, cities, roads, passes, bridges of the Great Sui Territory, the Great Wall of China from Liaodong in the east to the Khan Futu City in the west is like a vigorous dragon, rising to the vast sea, over the towering mountains, through the vast grassland, across the vast desert, undulating on the top of the mountains, It outlines the national line of the Great Sui or curved or straight, and is full of majestic artistic charm.

This is a Great Wall of 10,000 miles longer than the Ming Great Wall from Hushan in Liaoning on the bank of the Yalu River in the east to Jiayuguan in the west, and the territory included in it is even more extensive, which is related to the strong and domineering of the Great Sui and the concept of not much territory in Sisai.

Seeing Yang Tong staring at the Great Wall, Li Jing said with a smile: "In the long history, Yinshan has always been the forefront of the Central Plains and the northern nomads. If the Central Plains Dynasty occupies Yinshan, the nomads will be forced to retreat to Mobei; If the nomads occupy the southern foot of the Yinshan Mountains and have fertile Monan grasslands and Hetao Plains, their strength will be greatly increased, and the Central Plains will lose the barrier and the door will be wide open. Meng Tian of the Qin Dynasty led the army to defeat the Xiongnu, captured the land south of Yinshan, and set up Shuofang, Yunzhong, Jiuyuan and other counties. In the chaotic times at the end of Qin, Chu and Han contended, the Xiongnu took the opportunity to recapture Yinshan, and their strength soared. It was not until Emperor Wu of the Han Dynasty that Yinshan was completely recaptured, and the Hetao Plain at the southern foot of Yinshan was firmly in his hands, and the Xiongnu could only flee, and there was no royal court in Monan (south of Yinshan) from then on. Now the tall and majestic new Great Wall directly envelops Yinshan in the south and becomes the second line of defense in the north. ”

"The Great Wall is good, but we can't treat it as an insurmountable barrier." Yang Tong sighed and said: "The Great Wall of Qin starts from Lintao in the west to Yalu Water in the east, and it is built on the basis of the existing Great Wall of Qin, Zhao Great Wall, and Yan Great Wall. The Han, Wei and Jin dynasties also built the Great Wall, and Qi Zhi Gaoyang also built the Great Wall of Qi second only to the Great Wall of Qin and the Great Wall of the Han Dynasty in order to consolidate the northern border defense and defend the Northern Zhou Dynasty. Emperor Wu of this dynasty also built the Great Wall of the Purple River, and the new Great Wall that I am building now is even more unprecedented. For generations, we built the Great Wall for two purposes, one was to isolate the nomads, and the other was to keep the surrounding enemies out, but we finally found that the Great Wall only had a temporary effect, and would not work forever. ”

"What is the Great Wall of Qi? I thought it was Gao Changgong and Hu Luguang, and they were demolished by Gao Wei; The Shuofang Great Wall and the Zihe Great Wall of my Great Sui are very tall and strong, and as a result, Liang Shidu and Liu Wuzhou demolished them respectively... If my descendants are not virtuous, this Great Wall will be torn down sooner or later... Therefore, it is impossible for the Great Wall of Death to be useful for a long time, and the Ming monarch and the people's hearts are the real Great Wall of steel. ”

"To tell you the truth, before I built this Great Wall, I was already prepared to be demolished." Yang Tong finally said.

"......" The silent crowd invariably showed a wry smile: Everyone agrees with these words, but only Yang Tong dares to say it.

"The original intention of building the Great Wall is to protect the border people, and secondly, I hope that future generations will have the Great Wall as a line of defense and can forge ahead without worries. In addition, there is a deeper purpose. ”

"What's the deeper purpose?" This time, everyone dared to speak and asked out loud.

"Do you think Emperor Wu built the Great Wall of the Purple River to defend against the Turks? Naturally not! Yang Tong continued: "Emperor Wu built the Great Wall for three years, Qimin Khan did not even have the courage to be an enemy of the Great Sui, Emperor Wu not only did not take the Turks in his eyes, but also looked for enemies all over the world. ”

Li Jing, an old minister of the Three Dynasties, thought about it carefully, and nodded in agreement: "When Emperor Wu toured the north, he led countless troops, and it seemed that he did have the intention of attacking the Turks, but the Qimin Khan not only paid tribute to more than 20 million cattle and sheep, but also personally weeded and opened the way. It's so respectful that people are reluctant to fight. ”

"It was also that northern tour, Yu Wenhua and Yu Wenzhihe, who accompanied the driver, violated the ban and took contraband such as pig iron, salt, weapons and armor, raw materials for bows and arrows to trade with the Turks, Emperor Wu was furious when he learned that Princess Nanyang came forward to intercede to exempt the Yuwen brothers from the death penalty. But after this case, Emperor Wu built the Purple River Great Wall in order to prevent unscrupulous merchants from transporting forbidden goods to the north. In the case of the Great Wall, which has a sparse garrison and is not visible, thousands of people only need to storm one place and break it immediately. Therefore, the Great Wall seems to be tall and majestic, but it is actually remarkable that it can defend against unscrupulous traders and small groups of enemies going south. It is more about giving the border people a sense of spiritual security. ”

Everyone was stunned, they always thought that the Great Wall was to resist the nomads' southward iron horses, but they didn't expect Yang Tong to say that the Great Wall was a showcase, and its main role was only to prevent the caravan from selling forbidden goods to go north, which completely subverted their understanding of the Great Wall.

"The words about the Great Wall should be recorded, even the flowers and the like must be remembered, and archived as a core secret, and every generation of emperors in the future must read it, don't think that with the Great Wall, you can get drunk and dream of death." It was also because all the core members present were the core members, otherwise Yang Tong would not dare to say so much.

"Whoa." The crowd responded awe-inspiringly, and this is really no joke.

Nomads, like them, fall into the blind spot of thinking, thinking that the Great Wall is very great, if they know the essence of the strong outside the Great Wall, one day suddenly launch a fierce attack on a certain Great Wall, with the sparse Great Wall defenders, really can't hold for an hour or two, this can be related to the affairs of thousands of generations, can hide for a while is a moment, can never be publicized to the outside world.

"Holy Lord, Weichen has something to say." Jiang Xingben said.

"Please."

"The Ministry of Industry has collected a large number of magnets from Qingzhou and Jizhou, and this kind of stone swings at will, always pointing in the same direction, which is why it can make a compass pointer, in addition to this feature, it can also suck up a small piece of iron, if the magnet stone is installed at the gate of the border city, it will be able to search for pig iron, iron prohibition of the miraculous effect." Jiang Xingben said with a smile.

"You've got a great idea, but can it afford to slash a sword?" Yang Tong is very excited, the magnet is a natural magnet, but its adsorption power does not seem to be enough, and it is impossible to suck away the sword from afar.

Jiang Xingben said: "The sword armor definitely can't absorb it, but the sword armor can suck away small pieces of magnets. If you place a small magnet with a bell on the top and bottom of the gate hole, the bell will make a sound when it is sucked away. ”

"You can give it a try." Yang Tong nodded, and said: "But I think I can still make an article on the suspension bridge, if the two are combined, it will definitely achieve twice the result with half the effort." ”

"Please make it clear to the Holy Lord."

"A cart of pig iron and a cart of fur of the same size, their weight is different, if the other side of the drawbridge is a few inches above the ground, then when they cross the bridge, the drawbridge sinks to a different depth, and the chain buckles used are also different."

"The saint is saying that the suspension bridge is designed as a large scale?" Jiang Xingben's heart moved.

Yang Tong nodded and said, "Exactly." ”

"There is a lot to be done, but Wechen needs to build a city gate and a drawbridge to test."

"Of course."

。。。。。

Just as the Great Sui monarchs and ministers were talking, a team that was a little down, but always maintained a guard of honor, appeared outside Daxing City, which was a little out of place with the crowd coming and going.

"Who are those?" The soldier at the gate pointed to the group coming from the east, these people had light skin and thick beards, they were the opposite of the tall bearded people of the Western Regions, they were very short, and their strange appearance naturally aroused the vigilance of the guards.

"It seems that it's not my people of the Great Sui, nor is it the Hu people of the Western Regions, let the brothers be vigilant!" Although the captain of the city gate did not think that there was a problem with the group of people who had crossed the Tongguan Pass to Daxing, there were more than 200 strange people in this group, and the captain still issued an order in accordance with the regulations to let 300 elite soldiers come down from the city and block the way of this group.

The captain stepped forward and said loudly: "Stop!" ”

The procession, which looked like a victim of the disaster, immediately stopped, and one of them slowly stepped out of the ranks, and said very humbly in jerky Chinese: "We are not enemies!" ”

The captain found that this man was thin and small, but he was wearing the clothes of an adult Han man, which was obviously very loose. That's it, the key is that this is not very old, but he has a full face and beard, which looks extremely strange. He looked at the others again, and found that one or two of them were also strange-looking, looking no different from refugees, and he really couldn't see any danger in these people, so he suddenly became interested, looked around this person, as if he had found a great rare animal, and asked, "Where did you come from?" ”

"We are a group of Ezo envoys from the sea, and we are here to meet the Emperor of the Great Dynasty!" The visitor was furious, and knelt on the ground very humbly, his forehead touching the snow, and his voice carried a sincere meaning.

The lieutenant was stunned. He knew that some foreign envoys would come to Jin to see the emperor one after another, but he really hadn't heard of this thing, this should be an uninvited foreigner, so it was not on the list issued by the imperial court, since the Tongguan garrison had been released, there should be no danger, but this kind of thing, not a captain can decide.

"You guys are waiting here, I'll report it." The lieutenant commanded.

"Okay, okay, the general doesn't have to worry, we can wait......" The person who came nodded and bowed respectfully.

"Hmm." The other party's respect and humility made a sense of pride in the heavenly kingdom spontaneously arise from the captain's heart, and his body straightened up.

"Chief, what are these things?" When the lieutenant returned to the city gates, a brigade commander stepped forward to ask.

"They are not things, they are Ezo envoys who came to worship the saint, claiming to be from the sea, but this Ezo is not on the list, and I can't let them go." Speaking of this, the captain commanded: "You take care of them, I will go to the city to report." ”

"Whoa." The brigade commander agreed.

The school captain galloped into the city, ran straight to the official office of the Ministry of Rites, found Zhang Xuan, the left waiter, and saluted: "Chen Chong, the captain of the East City Gate, see Zhang Shilang." ”

"Excuse me!" Zhang Xuan returned the salute and asked, "What are you looking for me?" ”

"Back to Shilang, a team of Fanbang envoys came from outside Dongcheng, saying that it was a pilgrimage to the saint."

"Fanbang envoy?" Zhang Xuan was surprised: "There are a lot of envoys from Fanbang from the east, have you asked who they are?" ”

"The people who took the lead said that they were from a place called Ezo, and that Ezo was in the sea, and they didn't know the truth or falsehood." Chen Hao said.

"Ezo is a genus of Wakoku, and it is true that it lives in the sea." Zhang Xuan explained to Chen Hao.

"Thank you for your doubts, it's just that this group of people is not on the list, do you want to blow them away?"

"After all, it is the people who come to worship, and the boom must not be blown away." Zhang Xuan shook his head and asked again, "How many people came?" ”

Chen Hao bowed down and replied: "There are more than two hundred here, it looks like a refugee, but it's ......."

Chen Hao wanted to speak and stopped.

Zhang Xuan was surprised: "But what? ”

"These two hundred or so people are short and thin, and they are estimated to be less than our number one hundred people combined."

"It's not surprising that the people of the sea and the people of Ezo are like this." When Zhang Xuan heard this, he angrily and funny ordered: "Take them to the post house to settle down, let the soldiers keep a close watch, and don't let these foreigners make trouble in the city." ”

"Yes."
