The Liu family army's attack has always been launched near the city gate, because only by capturing the city gate can their army continuously drive in and capture the city.

This is basically all the methods of siege.

But what they are attacking now is the world-famous city of Nanjing. This famous city is high and deep, easy to defend but difficult to attack.

In order to build this city, Emperor Taizu Zhu Yuanzhang mobilized millions of people from four provinces to carry out large-scale labor service. It took four years to build this huge city. It was built with the world's first standards and also to build a giant fortress with both offense and defense.

This giant city did not play its role as a military fortress in its 200-year ups and downs. Until more than 260 years later, it finally used its tall city walls to defend foreign invaders and preserve the world of the Ming Dynasty.

But Duke Xu, who was responsible for defending the city, had no joy at all. Although many people in the city praised him and even praised him as the God of War, compared with her ancestor Xu Da, he was not happy. He was in awe of the huge military camps, neat queues, and the daunting red cannons outside the city.

Since ancient times, those who defended the city were able to attack and then defend. Only by both attacking and defending can they defend this city. They can only rely on the tall city walls to resist hard, and they dare not go out of the city to fight the enemy.

When Zhang Xun guarded Suiyang, he went out of the city to attack Linghu Chao's rebels repeatedly, which caused huge casualties to the other party. However, they are just relying on the city to persevere and dare not fight at all.

On the one hand, the soldiers were unwilling to fight. Even if he made a generous reward and asked these soldiers to go out, they said they were unwilling to go out, because they all knew that these soldiers were as powerful as the Tianxiong Army, and they were defeated by Liu's army head-on. There were so many armies in the Ming Dynasty, and even Jiannu were defeated by Liu's army. They would be dead when they fought with Liu's army.

There is another Duke Xu himself who believes that as long as you keep the city of Nanjing now, it is enough to fight easily and easily be caught by the other party. If you go out to fight because of your greed for merit, you will be killed by the other party, which will be a huge loss.

That's why they caused such a situation. They didn't dare to fight at all. Their defense of the city became passive. Duke Xu was worried. This was more difficult than he imagined. The main reason was that the siege had been for ten days. They had not yet arrived at a reinforcement from outside, nor had any grain teams from outside successfully arrived. If someone here successfully transported grain here or reinforcements arrived, they could give them great motivation.

This shows that the other party's blockade is airtight and there will be no chance.

Now, no grain team arrived and no reinforcements arrived, which shows that Liu's blockade was extremely powerful, and the court was unable to send a powerful army to support the place.

Duke Xu was born in a family of generals and was considered a soldier. He knew one thing, that is, the current Liu army besieged in the city, with hundreds of thousands of people. If the court wants to send reinforcements to rescue Nanjing, it has to send a heavy army group.

If it is a small-scale army, not only will it not be able to lift the siege of Nanjing, but to put it bluntly, it is coming to deliver vegetables.

There are not many heavy army groups in the Ming Dynasty now, and there are not many who are able to come to rescue Nanjing. There are only two troops in the south, one of which is the fleet of the Zheng family in Fujian. They advance west along the river and can arrive as fast as possible.

But the worst news came, that was that there was a military coup in the Zheng family. Zheng Zhibao, who supported the Liu family, took power. The Zheng family had completely turned to the Liu family, which left them hopeless.

Another heavy army group is the Southwest Army led by Zhu Xieyuan. The Southwest Army is also a battle-capable force. They have been encircling and suppressing the water-capable soldiers in the deep mountains and forests of Guizhou. They have been in battle for a long time, which shows that they are a battle-capable force.

It is estimated that when the imperial court heard that Nanjing was besieged, they would call them immediately, and they would come soon, but it was impossible to come from the deep mountains and forests of Guizhou to Nanjing, and it was a large army. It was probably not possible to have less than three or four months. In this way, Duke Xu understood that the defense of Nanjing City was a long-term and arduous task, and he had to prepare for long-term combat.

The war was cruel, and there was no doubt about it. At the beginning, Liu Jun just used cannons to attack the city wall. After it didn't work, they used a rush-made catapult to throw a large number of fireballs and oil bombs into the city, causing a raging fire, with the goal of creating panic.

Duke Xu had no good way to deal with this strategy. He just ordered all the houses near the city gate to knock down to avoid causing fires and endangering the city, causing fire everywhere in the city. The battle only took a few days to start, which caused such consequences. Once it continued for a long time, God knew what kind of disastrous consequences would be.

Duke Xu knew that the future would be more difficult, so he made sufficient preparations. He had already provided quota for grain supply in the city, which was to collect all the grain in the city and manage it in a unified manner. Only those who went to defend the city in war could have enough food, and other people could only eat one and a half full.

And there was also a death order. This order is dead and no one is allowed to violate it. This is food as a control product, and only the army allows it to own it. Those who dare to store food privately will be beheaded. No matter who you are, they will be beheaded if they catch it. This allows them to collect a large amount of food in a short period of time.

It would be no problem to get these foods to last for several months.

In order to defend Nanjing City, Duke Xu also thought and used all the methods he could use. He basically stayed on the city wall every day. Since the war began, he had never returned to his Duke's Mansion to live. He always ate and lived with the soldiers. It was because of this that he could make the soldiers willing to work for him.

Duke Xu was thinking that I had done everything I should do. Whether I could defend this city depends on the luck of the Ming Dynasty.

Liu Zhongyong still attaches great importance to Situ's only plan. He ordered his elite soldiers to take advantage of the darkness and the cover of his brothers to quickly bury thousands of kilograms of explosives under this section of the city wall.

Because this is a moat section, they can only use small boats, coffins to load explosives, then transport them with small boats, fix them next to the city wall with small boats, and then ignite the leads to prepare for explosion.

Only a loud bang was heard, and thousands of kilograms of explosives began to detonate. The people near the city gate were deafening and almost unable to stand steadily. With the huge rumbling sound, the entire section of the city wall was blown down.

After the explosion of this section of the city wall, Liu Zhongyong did not order the troops to launch a charge immediately, but ordered the ten red-clothed cannons prepared here to continue shelling the huge gap and continuously bombard the gap, striving to make the gap bigger and wider.

Amid the roar of cannons, they also had some troops who quickly transported the prepared prefabricated parts and assembled them quickly. They were trying to build a pontoon bridge in this moat section so that their troops could pass quickly.

After all, there were many defenders in the city. They patrolled the city day and night. Outside the city wall, so many Liu troops gathered here inevitably alarmed the other party. However, the defenders reacted a little too late. When they determined that this might be one of the main attack directions of Liu's army and dispatched elite troops to intercept, Liu's army had already used explosives to blow up the city wall for a section.

Duke Xu also judged that this place was one of the main attack directions of Liu's army, so he led his most elite servants to defend here.

When the city wall was blown down, he was really stunned, his heart was as cold as iron. He said to the soldiers loudly: "To make achievements, today! Follow me to kill the enemy."

They saw that the city wall was blown up instantly and collapsed instantly. All this was unsustainable, so they ordered their most elite soldiers to prepare to face the possible impact of Liu Jun after the city wall.

They all believe that when the city wall collapses, Oxford is rushing in with all his might, as soon as the city wall collapses, he starts building a pontoon bridge to prepare for a quick attack.

However, when they lined up here, holding shields and wooden boards, ready to welcome Liu Jun's attack, they did not welcome Liu Jun's attack, but came towards them, Liu Jun's rain-like shells.

A large number of shells were smashed into the gap, so that the Ming soldiers who lined up behind the gap in the city wall were blown up one by one. They formed a military formation and were blown up in pieces, with heavy casualties.

These soldiers held shields and wooden boards. These shields and wooden boards still had a certain effect on the Liu family's bows, arrows and projectiles, but if they wanted to deal with the bombardment of the Liu family's cannon, it would be useless.

The Liu family's red-clothed cannons smashed hard and plowed several flesh-and-blood alleys into their formation. With such a dangerous environment and such a fierce scene, even the most ferocious soldiers were all jealous.

This made them face a close collapse in an instant. Duke Xu was standing here on a horse, preparing to lead the soldiers to fight, but saw countless projectiles blowing into their positions like raindrops, which caused them to suffer heavy casualties and very tragic. The army he faced was almost deadly blood.

As the sky was covered with blood, they screamed and fell down in pieces.

Just as he ordered the soldiers to reorganize the team, a large number of Liu's soldiers, holding shields, rushed in through the gap, shouting and rushing towards the positions of the government army.
