Under the city of Hanoi, the five-clawed golden dragon flag fluttered, and although the Ming army only had 20,000 iron horsemen, it had a compelling momentum.

On the city wall, a general of the Annan army observed the situation of the Ming army, and immediately ran down the city wall to report to the king of Annan.

"The Ming army actually sent iron cavalry!"

"Rubbish! It's all rubbish! "King Annan was so angry that his face turned blue!

Although the army did send iron cavalry, the speed of maneuvering was very fast, but the three fortified cities such as Lao Cai and Liangshan in the north guarded the main road, and the iron cavalry was generally not good at attacking the city, but the Ming army actually went down to the three cities in one day, and the king of Annam could not imagine how incompetent the defenders of the three cities were, so he could not even block the Ming army for a day.

"I, Annan, am not a vegetarian either, and I will not perish here!" King Annan gritted his teeth.

There are only 20,000 iron cavalry in the Ming army, even if there is a large army behind, it is expected that there will be more than 100,000 at most, and he has nearly 140,000 Annam elites in Hanoi City, and he will not be without the strength of a battle, so although the king of Annam has some heart palpitations, he is not desperate!

Hanoi is the capital of Annam, leading the river into the city, the moat is wide and deep, it is the strongest city in Annam, for many years for Annam to resist the attack of foreign enemies and rebellions, even if it is compared to Xuzhou in the Central Plains, Nanjing and other fortified cities are just a line worse, the king of Annam wants to rely on this fortified city to let the Ming army hit the head and break the blood, and has no choice but to retreat!

Outside the city, looking at Hanoi surrounded by a moat, Zhou Cao did not plan to attack the city directly.

Although the city of Hanoi is strong, but for the current Ming army, the city wall is no longer enough to resist their attack, even if there is a moat to block, but whether it is to blow up the city wall or blow up the city gate, Zhou Cao has several ways, but at this time, the Annan army in the city has not suffered much blow, and there is still some morale, and there are many houses and buildings in the city, if the Annan army cannot be defeated at the first time, it is easy to have street battles, causing heavy casualties to the Ming army, every soldier of the second army is precious in the eyes of Zhou Cao, and it is not a last resort. Zhou Cao didn't want to sacrifice anyone.

"Order, prepare for the shelling of Hanoi!" Zhou Cao ordered indifferently.

Before the siege, he planned to bombard Hanoi for a period of time, destroying at least some of the buildings inside, and completely crushing the morale of the soldiers of the Annam Army inside.

Soon, all seventy-six field artillery pieces of the Second Army were lined up at a distance of five hundred meters from the city walls.

Cannonballs into the chamber!

"Fire!"

"Boom Boom"

Indiscriminate shelling, whether it is the city walls of Hanoi or the city, or even the palace of Annam, where the king of Annam is located, shells may fall.

Houses and buildings were blown up, soldiers and civilians were killed and wounded, fires began to ignite in some places, and the whole of Hanoi was plunged into a sea of fire, running and shouting, chaos and fear.

Although there were only 76 artillery pieces in the Second Army, because of the fast rate of fire and the huge power of the shells, the threat was no less than that of the 500 red-coated cannons, which were famous siege weapons in the world.

A dozen red-coated cannons are enough to make people fearful, and they can break through a fortified city, and now the Second Army Artillery Battalion, which is equivalent to at least 500 red-coated cannons, can imagine what kind of shock and fear it gave to the Annam army and the people of Annam in Hanoi.

Hanoi is the capital of Annam, and it is also the largest city in Annam, which can accommodate up to 200,000 people, which is the limit, but the king of Annam has mobilized nearly 140,000 elites in the city, and the people in the city and the Annam army are extremely dense.

At every turn, soldiers and civilians of the Annam Army were killed in artillery fire.

"Boom Boom"

After a few more cannon shots, a palace in the palace of Annam was blown up, killing many palace maids and guards.

The king of Annam did not dare to stay in any palace any longer, and under the protection of a group of guards, he hid at the foot of a rather thick wall with a pale face.

"The artillery of the Ming army is so powerful! It's even more powerful than rumored! King Annan's voice trembled.

The rumor that the Ming army has powerful firearms has spread to Annam a few years ago, the king of Annam has not seen the firearms of the Western Hongyi, only thought that the firearms of the Ming Dynasty are at most similar to the Western Hongyi, in order to take advantage of the fire to rob the city and territory of the Ming Dynasty, the king of Annam once gritted his teeth and bought five red-clothed cannons with the Portuguese at a high price, and now they are placed in the city, and he is preparing to find a way to transport them to the city wall to bombard the Ming army outside the city, but at this moment he knows that he is wrong, the cannon of the Ming Dynasty is much more powerful than the Westerners, His five red-coated cannons, which he had purchased at a high price, were blown up by the Ming army's cannonballs before he could even think of a way to transport them to the city wall.

"Boom!"

Under the dust, smoke and firelight, another palace was blown down, and there were few palaces left in the entire royal palace.

King Annan's heart is dripping blood!

"Newspaper"

"King, the Ming army is under fierce artillery fire, and the soldiers and people in the city have suffered heavy casualties!" A general of the Annan Army approached the king of Annan to report.

King Annan's face turned black, his teeth were almost crushed, and at the same time, he became extremely frightened in his heart, the Ming army only came 20,000 iron horsemen outside the city, and it actually brought such a fierce artillery fire, once the main force of the Ming army arrived, wouldn't it be several times more violent! I'm afraid that the whole of Hanoi will be bombed into ruins, and he himself does not know when he will be blown up!

King Annan didn't know that the 20,000 Ming army iron cavalry outside the city was the main force of the Ming army, and he couldn't find out the specific situation, so he could only scare himself.

Some of the Annan officials who followed King Annan were also frightened, and their faces turned pale with fear.

"King, the Ming army is strong and invincible, let's find a way to negotiate peace with the Ming Dynasty! No matter what conditions Da Ming proposes, at least let Da Ming stop shelling first, Da Wang! "Some Annan officials suggested that they were afraid that a shell would explode next to them and kill them at some point.

Looking at the walls of the palace that had not been destroyed in the explosion of the shells and the guards who had been killed, King Annam was full of powerlessness.

"Then negotiate peace, this king will write to the generals of the Ming army outside the city, and ask them to stop the shelling first!" Although the king of Annan was unwilling, he expected that the Ming Dynasty would only return to the occupied small county towns at most, and would not necessarily destroy him Annan country.

In the midst of the fire that exploded in the palace from time to time, King Annam quickly wrote a letter asking for peace.

Watching the guards send the letter of peace to the Ming army outside the city, King Annan sighed weakly, in addition to returning to those counties, the Ming Dynasty may not only want to go back to those counties, but also blame him and order him to abdicate!

The king of Annan is unwilling, the Ming Dynasty has been established for nearly three hundred years, and he should have run out of gas, and he Annan can also take the opportunity to get a piece of the pie, but he didn't expect that the Ming Dynasty would be prosperous again in just a few years, and he would be strong again!

It can be said that stealing chickens is not a counter-erosion of a handful of rice!

Although he may abdicate, as long as he does not destroy the kingdom of Annan, one day he will wait for the Ming Dynasty to decline again.

The king of Annan is very ambitious, and he also fulfilled Zhu Cijiao's words, between countries, there are only interests again, no matter how many years Annan has been a subject of the Ming Dynasty and how much favor he has received from the Ming Dynasty, as long as there is an opportunity, they will also incarnate into white-eyed wolves without hesitation, and bite the Ming Dynasty fiercely.

King Annan didn't know that the purpose of the Ming Dynasty from beginning to end was to destroy the Kingdom of Annan, not just a simple punishment like the previous dynasties, and he didn't know what kind of expression the King of Annan would have after learning that the Ming Dynasty was determined to destroy Annan.
