Liu Cong continued, "This dynasty began to renovate Chang'an City, making it as strong as an iron barrel. They also changed the name of Chang'an City and called it Xi'an.

The Ming Dynasty first built its capital near the current Jianye. Later, after the founding emperor of the Ming Dynasty died, his son and grandson fought for the throne and fought fiercely. Finally, his son who led troops to guard the border in the north defeated his grandson, and then took the capital. After moving to the north, it is now south of Yanshan, and the capital is called Beijing."

When Liu Cong said this, Wei Yan, Xu Shu, Zhou Cang, Guan Ping and others were all fascinated.

Liu Cong took a quick look and saw that they were all stretching their necks like a group of stupid ducks to listen to his story. He immediately woke up and said to himself: "What can I do if I tell these things to these few people? They won't go to college. Damn it." Hu Lielie”

So he stopped talking and said: "Where did this go? It's too far off. Haha, it's too far off.

Everyone thinks how Cao Cao will plan his way out at this time."

Xu Shu then said: "My lord said that he wanted to tell us about the geographical situation of Chang'an. We are all waiting to hear it. My lord has already talked about history. Don't ask Cao Cao how he will plan for himself at this time." Now that we have a way out, let’s finish explaining the geographical situation of Chang’an to us first.

Haha, we haven’t been to Chang’an yet, so we just want to hear some insights.”

When Xu Shu reminded Liu Cong, he remembered it and said with a smile: "By the way, I was going to talk about the geographical situation of Chang'an, but Wei Yan interrupted me. Okay, I'll start from the beginning. Don't interrupt me." That’s it.” Everyone agreed [

Liu Cong said that Chang'an City is really built in a good place. It should be said that there is no better place in the world to build a capital than here. It covers almost the entire Weihe River Basin of 800 miles of Qinchuan. Everyone knows it”

How do you know that they are all people who took advantage of the chaos in the world to leave their hometowns and come out to live a casual life? Except for Xu Shu, they are all farm men who do not read books or newspapers. Who cares about the Eight Hundred Miles of Qinchuan? What kind of ghost place is this?

Even Xu Shu only knew the historical conditions of Chang'an and did not necessarily know the geographical conditions here.

So Xu Shu said: "Who knows what the meaning of Eight Hundred Miles of Qinchuan is? Only a god like my lord who knows astronomy and geography knows it. Just talk to me. I also know some of the history of Chang'an from "Historical Records", but I don't know. know the geography

What about the Wei River Basin? I only know about the Yangtze River and the Yellow River. Where do I know about the Wei River?"

Now Liu Cong found the speaker and ordered Xu Shu: "Hahahahahahahahahaha, sir, please tell me the history of Chang'an."

As Liu Cong spoke, he picked up the tea cup and took a sip to moisten his throat and urged Xu Shu: "Speak, Mr. Xu."

Xu Shu said: "I just know some things from history books, which may not be correct."

"You can just tell me, this is not an exam room."

Xu Shu said that he started from the Yellow Emperor and then mentioned the Yellow Emperor's Mausoleum, "It's just in the north, about five hundred miles north of Chang'an."

Next, we will talk about the Xia Dynasty, Shang Dynasty and Zhou Dynasty, and then talk about King Zhou Ping moving east to Luoyang. Luoyang was called Luoyi before. "The reason why the Zhou Dynasty was divided into the Western Zhou Dynasty and the Eastern Zhou Dynasty is because the capital of the Western Zhou Dynasty was in Fengyi and Gaoyi, and the Eastern Zhou Dynasty moved to Luoyi."

I don’t know if what Xu Shu said is right or not. Anyway, he was talking eloquently at this time, and everyone was fascinated by it.

Xu Shu descended from the Spring and Autumn Period to the Warring States Period, and then began to talk about the Pre-Qin Dynasty, starting from the ancestors of Qin Shihuang and continuing to the unification of the Six Kingdoms and the Three Generations, which were overthrown by Chen Sheng, Wu Guang, Liu Bang, Xiang Yu and a bunch of other bastards. When Xu Shu talked about this, Liu Cong took the lead. The palm said: "The exciting part is here, everyone, listen carefully and listen to how Han Gaozu was enfeoffed to Shu as a thief, how he openly built plank roads and secretly led Chen Cang to fight out of Hanzhong and compete with the Chu Overlord for the world."

Xu Shu really followed Liu Cong's thinking and talked about the establishment of the Western Han Dynasty before clearing his throat and saying: "I don't know if there is any confusion in what I said. Anyway, the general historical situation is like this."

Liu Cong smiled and said: "Very good, very good. After all, he is indeed an old scholar full of knowledge. Haha, don't you want to hear Cao Cao's plan at this time? I will understand it as soon as I remind you." [

Liu Cong said: "At this time, even though Cao Cao is not at the end of his rope, he will correctly understand his situation.

He will definitely realize that he no longer has the strength to compete with us in the Central Plains. But as we said before, Cao Cao is a person who is unwilling to give up easily.

He won't admit defeat now because he still has hope and capital.

Cao "Cao" has these capital, more than 100,000 Xiliang troops, 800 miles of Qinchuan's nurturing land, starting from Chang'an all the way to the northwest through the Hexi Corridor and entering the vast area of ​​​​the Western Regions. These are enough to support Cao "Cao" to defend Tongguan and then in Guanzhong. Dominate the land and compete with the Luoyang court

Once Cao Cao took control of the above ground, the important people and people in this place wanted food and food. With Cao Cao's ability and talent, he could go south to occupy Hanzhong and Yizhou and form a separatist situation with the imperial court, which would become a huge obstacle to the unification of the country.

Do you think my analysis like this is correct?"

After hearing this, everyone sighed and nodded in agreement as if they were just waking up from a dream.

Liu Cong continued: "The military advisor before us introduced the process of Qin Shihuang's unification of the six countries. In fact, the two countries fought and fought based on the strength of both sides. The Qin State relied on the food and soldiers provided by the eight hundred miles of Qinchuan in the Guanzhong Plain and was eliminated step by step. The six kingdoms gradually unified the world

Haha, everyone knows that Emperor Gaozu of the Han Dynasty was sealed in the land of Shu. When Gaozu entered Shu, he burned the plank road while walking. The purpose was to show the Overlord of Chu that he would live in seclusion in the middle of Shu, the land of abundance. He would never come out to the Overlord of Chu if he lived there honestly. In the world of struggle

But after waiting for a few years, the military advisor Gaozu lived in Shu for a few years, and then secretly built a plank road in Chencang. He came out of the Chencang ancient road and started a fight with the Chu Overlord. Finally, he defeated the Chu Overlord and established the Han Empire."

I don’t know what Xu Shu muttered. Anyway, Liu Cong made a summary after saying this: "Some people in later generations wrote poems and said, 'It is better to keep the courage to chase the poor bandits, but not to sell the famous scholars to the overlords.' Today we are dealing with Cao Cao and we must carry forward the pursuit of the poor bandits." His spirit must not be like that of the Overlord of Chu who easily let Gaozu go to Shu and was killed by Gaozu out of Shu, forcing him to commit suicide in Wujiang River."

Liu Cong made this analysis and made a decision. Of course, everyone agreed, so they all geared up to fight: "My lord, tell me how to fight Cao Cao in a decisive battle. We will fight wherever you point us."

Liu Cong smiled and said: "Very good, very good. Now let me analyze the situation and let's look at the map."

When all the generals gathered around to watch, Liu Cong pointed at Tongguan and said: "Now that the news of Cao Zhang's defeat has reached Cao Cao's ears, Cao Cao will definitely not pretend to attack Hangu Pass. We will not send letters for the time being. Cao Cao will definitely withdraw his troops back to Tongguan if he marches into Guguan.

Everyone knows that Hangu Pass and Tongguan are two dangerous passes. The mountains are high and the valleys are deep. The roads are narrow and most places can only be passed by one person and one horse. If we attack Tongguan from Hangu Pass, we must overcome many difficulties.

I thought about it for a while and planned to win by surprise. All I need is this, hehehehe."

When the generals heard this, they clapped their hands and applauded together.

Liu Cong said: "But we have never been on this road before and are really not familiar with it. I'm afraid there are not even roads in many places. Where can we find a few guides?"

Wei Yan blinked and suggested, "Just order Cao Zhang to lead the way. He has led troops in Bingzhou and Youzhou for many years. How can he not be familiar with the road from here to Chang'an?"

Liu Cong thought for a moment and said, "It's not appropriate. Isn't it too unkind? I ordered my son to lead troops to kill his father. Hahahaha. Forget it. Most of our prisoners are Cao Zhang's subordinates. Since Cao Zhang knows the way, How could his subordinates not know that something great has happened?"

[On August 27, the 15th year of Jian'an, Liu Cong handed over major events in Hebei to Huang Zhong, Zhang Liao and Xu Shu, and then led three thousand Jingzhou cavalry all the way north to Shangdang County.

Before setting off from Yecheng, Wei Yan and others suggested asking Liu Cong to arrange more horses to carry grain and grass.

Liu Cong said: "The key to the army's surprise tactics is to come and go quickly. How can we consider everything comprehensively? As long as we are almost ready, we can act."

Looking at Wei Yan's confused look, Liu Cong smiled and said: "After years of melee fighting in this place in Yecheng, the bones have been exposed in the wild and the chickens crow thousands of miles away." Well, this is a poem written by Cao Cao, which says that this place is thousands of miles away. The crowing of the cock is a bit exaggerated, but there are really not many people. Since there are no personnel to recruit horses, we have to do this. As for the baggage, grain and grass, I have sent scouts to send letters to the Shangdang, Pingyang, and the Yamen of Hedong counties. Each Yamen has its own preparations."

It turns out that Liu Cong used surprise tactics when he marched into Chang'an. The path he chose was to march from Yecheng, pass through Shangdang, go all the way west via Pingyang County, Hedong County, pass Hukou Falls, and take Chang'an by surprise from the north.

After leaving Shangdang and crossing the Fenhe River and leaving Pingyang, we crossed the Yellow River and marched all the way to Beidi County.

Liu Cong originally designed the marching route when he was looking at the map in Yecheng. Only then did he realize that it was not realistic.

It turns out that the road out of Yecheng to Shangdang County is correct. But when we passed Shangdang County and headed towards Pingyang County, the guides said that it seemed wrong. They said that the map I saw at home was not accurate. I saw Pingyang based on the road I took on site. If you go further southwest from the county, you can reach Hukou Waterfall. However, crossing the Yellow River from Hukou Waterfall is not only difficult, but also the march to the east of Chang'an is the same as marching from Luoyang. Tongguan 016 is easy to defend but difficult to attack.
