Cao Zhen sighed and said: "This can only be appeased, you are each optimistic about your own troops, you must inspect the military camp every day, and you must not slack off, in case the soldiers mutiny." ”

"No!" The generals will take the command.

More than ten days passed in a blink of an eye, and Liu Chan had pacified Feng Xu County, led his troops south to Chang'an, and joined Zhuge Liang.

East of Chang'an City, Han military camp.

Since Chang'an City is Tongguan to the east, Zhuge Liang built the camp outside the east gate to prevent Chang'an from having contact with Tongguan.

In the big tent of the Chinese army.

Liu Chan sat in the first place and said with a smile: "I heard that Da Sima scolded the puppet Wei Sangong Wang Lang to death with a few words, but unfortunately I was not present and could not see such a strange thing." ”

Liu Chan was indeed sorry in his heart, Zhuge Liang scolded Wang Lang, which can be called the first wonderful scene of the Three Kingdoms, much more interesting than the Three Heroes Battle of Lu Bu, he actually missed it.

Zhuge Liang said with a smile: "Where is it, when the three generals were in Changbanqiao, Xiahou Jie was scared to death with an angry shout. ”

Zhang Fei waved his hand and said: "That Xiahou Jie is just a small role, Wang Lang is the third duke, and he is still a big Sima." I really don't know what Da Sima said, he can actually scold Wang Lang to death, I have heard that this person is the best at debating. ”

"Alright, let's get down to business." Liu Chan said with a smile: "When I first came, I saw that there were dirt mountains outside Chang'an City, and when the first emperor attacked Chang'an, Cao Cao was so defensive, right?" ”

When Liu Bei led his troops to attack Guanzhong, Liu Chan was still young and did not follow Liu Bei.

Zhuge Liang nodded and said: "Yes, at the beginning, the first emperor relied on the power of the return cannon to kill all the way to Chang'an, and Cao Cao dug into a mountain in order to defend against the return artillery. Now Cao Zhen is following Cao Cao's method of resisting the first emperor. ”

Zhang Fei sighed and said: "After this dirt mountain, the Wei army also deployed back artillery, and the eldest brother failed to conquer Chang'an in a few months. Now that the Wei army is also arranged, if we want to break through Chang'an, it will be difficult to climb to the sky.

I knew that after taking Longshan, I would not collect the city, and it would be good to kill it directly to Chang'an, so that the Wei army would not have time to dig the earth mountain. ”

Fa Zheng shook his head and said with a smile: "Kill directly to Chang'an, the rear convenience is unstable, the Wei army can detour to the rear of our army, and there will be constant riots, so the rebellion continues, and our army will be tired of coping."

And Chang'an City has been strengthened a lot in recent years, a few feet wide, if you want to break Chang'an with the return artillery, it is unlikely that there will be no three or five months, the three generals have forgotten why the first emperor retreated?

Although we can't break through Chang'an now, Chang'an has completely become an isolated city, and when its food is exhausted, Chang'an can naturally be obtained by our army. ”

Zhang Fei shouted: "When he finishes eating the grain and grass, he has to wait until when he goes." ”

"Okay, if you want to hurry, don't be in a hurry, now that the overall situation has been decided, it is only a matter of time before you take Chang'an." Liu Chan waved his hand and said to Zhuge Liang, "How is the situation of the Wei army?" ”

Zhuge Liang replied: "The soldiers and horses of Meixian, Huating, and Chencang have all returned to Chang'an, and Cao Rui still left 20,000 people, and now there are 90,000 soldiers and horses in Chang'an City. In Tongguan, Cao Zhen also sent 20,000 troops to garrison it. ”

Liu Chan groaned: "Our army has 150,000 soldiers and horses, as well as 5,000 cavalry, and in terms of strength, it is far superior to Cao's army. ”

Zhuge Liang sighed: "Even so, Chang'an is not a strong attack." ”

"Qing and the others will go out with me to see Chang'an."

"Your Majesty, please!"

Everyone left the camp and came to the high place outside Chang'an City.

Liu Chan stood at the top of the slope and looked at Chang'an City from afar.

Chang'an City stands in the hope of Weishui, all around, have dug a moat, lead to the water of the Wei River, and its river water through the city, it can be said that even if Chang'an is surrounded, Chang'an is not short of water.

Outside the city, there are all dirt mountains, and there are a large number of return cannons under the earth mountains, and there are soldiers to handle them, and it is impossible to break through Chang'an with manpower.

Liu Chan looked at Chang'an, and after a long time, he said: "The scale of this Chang'an City is a little small, less than half the size of Chengdu. ”

Fa Zhengben is a person from Guanzhong, he explained: "Since the rebellion of Wang Mang of the previous dynasty and the burning of Chang'an by the Red Mei army, Chang'an has lost its former prosperity, although Emperor Guangwu revived the Han Dynasty, but it took Luoyang as the capital, and Chang'an was the western capital, but it was not repaired on a large scale.

Moreover, in the past 100 years, the Qiang people have rebelled repeatedly, and have entered Kou Sanfu many times, threatening Chang'an, so that Guanzhong has no manpower and material resources to repair Chang'an. A few decades ago, Dong Zhuo and Emperor Xiaoshu entered Chang'an, but he only repaired part of the Chang'an Imperial City.

After Li Dao, Guo Yan caused trouble in the palace again, Chang'an became a ruin again, and now Chang'an has this scale, or from Zhong Xuan after sitting in Chang'an, slowly repaired. ”

Liu Chan muttered: "I want to take Chang'an as the capital, but such a scale is not possible, so this Chang'an has to be expanded." ”

Fa Zheng smiled and said: "Your Majesty said that you are laughing, at the moment, Chang'an has not been taken, how to expand?" ”

Liu Chan smiled and said, "How about I only build a city wall?" ”

"Build walls?" Zhuge Liang's eyes lit up: "Your Majesty is saying that a city wall will be built outside Chang'an to enclose Chang'an?" ”

Liu Chan pointed to the land in front of him and said, "Just use this place as the foundation of the city and enclose Chang'an City." ”

The area pointed by Liu Chan is more than 7,000 meters away from Chang'an City, plus the original scale of Chang'an, the side length has been nearly 10,000 meters, such a scale is enough to reach Tang Chang'an City.

Tang Chang'an City is the largest city in the history of the world.

Zhuge Liang was shocked when he saw this: "If this place is used as the base of the city to expand around, the scale of this city should be dozens of times the size of Chengdu, and it is several times larger than Luoyang. ”

"Once the capital of the country, how can you be so petty?" Liu Chan smiled and said: "In the future, the Han Dynasty will definitely come to the dynasty of all countries, and the population of the national capital can reach one million, how can you do it if you don't build a big one?" ”

"Hearing His Majesty say this, Weichen is fascinated!" Zhuge Liang smiled: "It's just that in this way, it will take more time." ”

Zhang Fei was confused when he heard it, and asked, "Your Majesty, military advisor, what are you talking about?" This Chang'an hasn't been taken down yet, why are you discussing building a city? ”

Zhuge Liang said with a smile: "Just build a city wall outside Chang'an City, enclose Chang'an City, and as soon as the city wall is erected, the Wei army will become a turtle in an urn, and there will be no sudden hope."

In this way, the Wei army will be in turmoil, and the soldiers and horses will mutiniate and surrender to Kaicheng. Our army has cement, and it is very fast to build a city wall, so that we can take Chang'an before the Wei army runs out of food.

And the newly built city wall can also be the capital of my Han Kingdom in the future. ”

Liu Chan asked, "How much time does Da Sima estimate it will take to build the city?" ”

Zhuge Liang muttered: "If you collect materials, this is the Wei River, the river sand is inexhaustible, there are also stone mines near Chang'an, and the forest trees are inexhaustible, and it is not troublesome." It's just that it takes some time to burn paper cement.

Moreover, there are 90,000 Wei troops in Chang'an City, and although our army has 150,000 horses, it is necessary to leave some men and horses to guard against the Wei army, so the available manpower is only about 50,000.

In this way, it should take a year to build a wall of this scale. ”

"It's not bad to be able to take Chang'an a year ahead of schedule and build such a big city." Liu Chan nodded with satisfaction: "Let's go back to the camp first and discuss this matter well." ”
