With Jiang Wei's order, the command flag waved in the large array of the Shu army, the rumbling war drums sounded to the sky, and all kinds of siege equipment of the Shu army began to operate.

First of all, the 30 thunderbolt carts began to throw huge stones towards the gates and towers of Chang'an City, and this time the thunderbolts were improved, and the huge stones thrown were wrapped in fire oil, ignited and then projected out, drawing long marks in the air formed by billowing smoke.

The boulder thrown by the thunderbolt weighed 300 pounds, and each launch was capable of making a thunderous roar. The violent sound of breaking the air was endless, like a continuous thunderbolt that kept hitting the walls of Chang'an City.

Immediately afterwards, more than 200 bed crossbows were pushed to the front of the formation, each bed crossbow was operated by five soldiers, four of whom were responsible for manipulating the machine, and one was responsible for placing the arrow and aiming, the range of the huge bed crossbow was almost the same as that of the thunderbolt, the average range could reach more than 300 steps, and some high-quality bed crossbows had a range of more than 400 steps.

Two hundred giant bed crossbows were fired at the same time, the sound of the bed crossbow breaking through the air was endless, and the arrows of each giant crossbow could show great power after they missed the city, some directly shot through a long line of Wei troops, and some even smashed the battlements on the city wall, and on the wall of Chang'an City, the Wei soldiers instantly became heavily wounded.

After gaining a firepower advantage over the Wei army, Jiang Wei ordered the siege vehicles to start to move forward, and sixty siege vehicles began to appear from the large array, and under the impetus of the soldiers, they quickly came to the outside of the moat, and then the soldiers pulled the long ladder folded on the siege vehicle, and began to stretch the long ladder to the other side of the moat section by section.

However, at this time, the Shu army had already entered the range of the crossbowmen in Chang'an City, and the Wei army at the head of the city began to frantically shoot arrows at the siege vehicles of the Shu army.

When the five sections of the ladder on the construction vehicle were fully unfolded, the length exceeded the width of the moat, and the soldiers easily crossed the long bridge and began to lay planks on the long ladder.

The ingenuity of this siege vehicle is that it eliminates the extremely dangerous work of filling the moat, and there are holes in the long ladder in advance, and the planks and holes fit together, so that the planks are very strong, like a wooden bridge.

In less than a moment, forty wooden bridges were formed outside the moat of Chang'an City.

Xiahou Nan and Xiahou Xuan at the head of the city glanced at each other, and they both saw surprise and despair in each other's eyes.

originally thought that the moat alone would be enough for the Shu army to drink a pot, but I didn't expect the Shu army to come up with such a thing.

As the wooden bridge crossed the moat, huge siege towers began to emerge in the military formation of the Shu army.

Each siege tower is as high as four zhang, the top of the tower stands with many crossbowmen, the bottom is equipped with wheels, the siege tower is slowly approached by the city wall of Chang'an City driven by the soldiers, the siege tower is divided into several layers, each floor is connected by stairs, once the siege tower is close to the city wall, the highest layer of the siege tower can put down the springboard, connect the city wall, there are Shu soldiers directly rushed to the city.

Seeing the huge siege towers outside the city, Xiahou Nan suddenly panicked in his heart, and sighed to Xiahou Xuan:

"This is obviously not the Shu army's previous tactics, in the past, when Zhuge Liang led the troops, he never liked to attack the city, and always used all kinds of tricks to lure our army out of the city, and then try to defeat our army. Therefore, this general is careful to keep a stable word, and the Shu army has always been helpless. Now this Jiang Wei doesn't need any strategy at all, and directly attacks Chang'an City, which is completely different from Zhuge Liang's approach. ”

Xiahou Xuan said: "Fei Ye, Fei Ye!" This Jiang Wei is also a scheming man, I have studied many Jiang Wei's battle examples, and Jiang Wei also likes to use stratagems to fight. However, in the face of a giant city like Chang'an, there is often no great use for strategy. Besides, the Shu army has as many as 120,000 troops, and the number of troops is far superior to mine, so there is no need to use too many strategies. ”

Xiahou Nan sighed: "Now there are only 50,000 soldiers and horses under my command and 3,000 soldiers and horses under your command in the city, and this bit of soldiers and horses is still overstretched to defend Chang'an, a huge city, I hope Your Majesty can send troops to rescue as soon as possible." ”

Xiahou Xuan said: "Don't worry, Your Majesty has decided to personally conquer, and mobilized several states of soldiers and horses, a total of 200,000 troops, will fight a decisive battle with Jiang Wei in Chang'an, as long as Your Majesty personally leads 200,000 troops to arrive in Chang'an, Jiang Wei will be defeated." ”

"Two hundred thousand troops!" Xiahou Nan was a little surprised, "Your Majesty really looks up to Jiang Wei!" So many troops were mobilized. ”

Xiahou Xuan said: "Princess Dongxiang, there is a high probability that she was captured by Jiang Wei, she is Your Majesty's only sister, do you say Your Majesty can not care?" However, it will take half a month for His Majesty to mobilize 200,000 troops, and then send troops from Luoyang to Chang'an, it will take some time, and when His Majesty's army arrives in Chang'an, it will be at least 20 days later, and we still need to work together to defend these 20 days. ”

When Xiahou heard that the reinforcements would not arrive until twenty days later, a wave of worry surged in his heart. If there was only Wang Ping's army of 60,000, Xiahou Nan was completely sure that he could defend it for several months, but now facing an army of 120,000, he was a little uncertain.

So he said: "Xiahou Xuan, Your Majesty appointed you as the governor, how to fight this battle, you should have an idea." ”

Seeing that Xiahou Xuan finally admitted his identity as the governor, Xiahou Xuan said with some excitement: "This matter has been thinking about this matter for a long time, and in order to win this battle, two things need to be done. ”

"Oh? Which two points? Xiahou Nan asked curiously.

"One is to mobilize the army of Wudu, Wudu has 20,000 troops under Cao Zhi, and 25,000 troops under Deng Ai, the two armies together, there are 45,000 troops, and now Wudu has become an island, they can only desperately go east and attack Jiang Wei's belly and back, so that they can have a trace of life, otherwise they will be trapped by Shu sooner or later."

Xiahou Nan's eyes lit up when he heard this, and he thought in his heart that if Cao Zhi and Deng Ai were willing to take the initiative to abandon Wudu and attack Jiang Wei's rear with all their might, then strategically, Jiang Wei would fall into passivity, and his total strength could rise to about 100,000 at once, and with the strong city defense of Chang'an City, it might be possible to repel Jiang Wei.

Xiahou Xuan continued: "The second is to hold the city, waiting for His Majesty's personal conquest, and when His Majesty's 200,000 troops arrive in Chang'an, the total number of troops invested by our Great Wei in this battle will reach 300,000, three times that of the Shu army, and it will not be easy to defeat Jiang Wei?" ”

Xiahou Nan knew that Xiahou Xuan was familiar with reading military books, and after listening to Xiahou Xuan's words today, he really felt that Xiahou Xuan still had some goods in his stomach, so he asked:

"Will Cao Zhi and Deng Ai choose to abandon Wudu and attack Jiang Wei? If he did this, if Jiang Wei temporarily stopped attacking Chang'an and turned his head to attack Cao Zhi and Deng Ai, then these two people would fall into a place of no return! ”

Xiahou Xuan was a little surprised: "Brother Zilin, what are you talking about?" If Jiang Wei turns around and attacks Cao Zhi Deng Ai, my Chang'an defenders will naturally take the initiative to attack Jiang Wei's abdomen and back, and form a flank attack with Cao Zhi and Deng Ai! ”

Xiahou Nan thought in his heart: "Okay, you Xiahou Xuan, it turns out that your strategy still wants me to get out of the city in the end, phew!" If you want Lao Tzu to lead the army out of Chang'an, there is no door, Lao Tzu has seen too much of the tricks of the Shu army, the best way is to hold Chang'an, and wait for His Majesty's personal army to arrive, why take this big risk? ”

So Xiahou Nan didn't want to answer Xiahou Xuan's words.

Xiahou Xuan, on the other hand, thought that Xiahou Nan had accepted his point of view, and now that he had sent someone to contact Cao Zhi, he believed that as long as Cao Zhi and Deng Ai's Wudu army arrived, Jiang Wei could be forced back.

The worst is that it can also allow the Wei army to hold on until the arrival of Cao Rong's personal army.
