On August 29, the seventh year of Zhongxing in the Ming Dynasty, the holy decree of attacking Annan was sent to Zhou Cao, the commander of the Second Army in Yongzhou.

"Okay, hahahaha, this time, it's finally my second army's turn to shoot!" Zhou Cao laughed.

He and Huang Degong, one commander attacked Annam, the other led the attack on Korea, and the two sides, one south and one north, prepared at the same time. However, Huang Degong's side made the first move, so that he and the Second Army had been staring at Yongzhou, Guangxi, looking at each other, and now that North Korea was destroyed, it was finally their turn to send troops to the Second Army.

"Order, assemble the army and set out for Annam!" Zhou Cao ordered in high spirits.

Due to the dense forests, the only place to really develop is the Red River Plain in Hanoi, so the current population of Annam is not large, only more than 3 million, and its national strength is much weaker than that of North Korea.

The Red River Plain is not only the most important granary of Annam, but also the location of Hanoi, the royal city of Annam. This is also why since the Qin Dynasty was included in the Central Plains Dynasty, the Annan Kingdom has been under the direct jurisdiction of the Central Plains Dynasty for more than a thousand years, and it was not until the Song Dynasty that it was able to truly break away from the Central Plains.

In fact, it is also simple to attack the Red River Plain, as long as you capture the old streets on the border of Guangxi, Gaoping and Liangshan, you can enter the Red River Plain, and at that time, the Red River Plain is a flat river, only a city in Hanoi can be regarded as a strong city, and the army can directly attack the city of Hanoi, so the combat process of attacking Annam is relatively simpler than that of Korea.

Because Annan's strength was much weaker than that of North Korea, and it was impossible for a force like the Japanese to intervene in it, Zhu Ciji only sent Zhou Cao's second army and 60,000 ordinary garrisons to attack Annan.

"Boom"

The Second Army carried all the war horses and formed an iron cavalry to attack, and it only took half a day to come to the border of Guangxi, and even the counties occupied by Annan did not directly enter the territory of Annan.

The mountain mouth camp on the border of Annan, where dozens of Annan soldiers guard the mountain pass.

Suddenly, the sound of rumbling horses' hooves was heard, and it was getting closer and closer, and the soldiers of Annan guarding this mountain pass were immediately taken aback and looked frightened.

As the first warhorse rushed into their sight, they saw the knight's garment on horseback.

"It's the Ming Army!" There were Annan soldiers who exclaimed.

"Go back and report to the general, the Ming army has invaded!" With the small leader of the Annan Army who led these dozens of soldiers shouted.

An Annan soldier immediately mounted the only war horse here and was about to run towards the rear, intending to inform the rear barracks and the generals of the Annam army guarding the city.

"Kill!" Zhou Cao ordered indifferently.

The Ming soldiers who rushed to the front raised their rifles and aimed at the dozens of Annan soldiers in front.

"Bang Bang Bang"

A shot was fired, along with the Annan soldier who was riding the only war horse and wanted to report the news.

Zhou Cao led 20,000 soldiers of the Ming Army of the Second Army into the territory of Annan, and the 60,000 garrisons left behind by the Second Army at this moment were still marching dozens of miles away from the border because they had no war horses, and they were afraid that it would take at least a few hours to reach the border.

The reason why Zhou Cao threw down the 60,000 slow-marching garrison and led the second army into the territory of Annan was to capture Laojie, Gaoping, Liangshan and other cities before the Annan army could react, and open the passage to the Red River Plain.

Because the regular army of the Ming army was all iron cavalry, it was extremely mobile, and after entering the territory of Annan from the border, Zhou Cao and the second army approached the city of Lao Cai in less than half an hour.

Because the soldiers of the Annan Army guarding the checkpoint along the way were all killed by the Ming army, the Annan army guards in Lao Cai City did not know the news of the Ming invasion at all.

Annam has been established for hundreds of years, the Central Plains Dynasty has not taken the initiative to attack Annam for more than 300 years since it invaded once in the early Yuan Dynasty, so the Annamite people have no defensive mind at present, and the Annan defenders guarding the gate of Lao Cai even because the afternoon sun is too big, only symbolically let one soldier take turns to collect the entrance fee, and the other Annan soldiers guarding the city gate are resting in a shaded place not far from the city gate.

As for the city wall facing the sun, there are no soldiers of the Annam Army, and it can be said that the entire Lao Cai City is in a defenseless state.

Suddenly, there was a rumbling sound.

"What sound?"

"Is it thundering? Is it going to rain? ”

The soldiers of the Annan Army who were resting in the shade were at a loss and couldn't hear what the sound was, and some even thought it was thunder, and they didn't know that it was the sound of a large number of war horses galloping.

I don't blame these soldiers of the Annan Army, after all, there are few horses in Annan, only high-ranking officials and powerful people and a few horses in some necessary places, and they have heard the sound of tens of thousands of iron horses galloping.

And the soldiers of the Annan Army patted their ears, thinking that they were hallucinating.

The only soldier of the Annam Army who stood in the middle of the city gate to collect the entrance fee looked curiously from a distance, but he heard the direction from which the sound was coming from, and knew that the sound was getting closer and closer, and it was about to appear.

Appeared!

The first thing that came out was a bright yellow five-clawed golden dragon flag!

With the appearance of the five-clawed golden dragon flag, a large number of Ming army iron cavalry rushed out and rushed to the city gate at a very fast speed.

The Annan soldier's eyes widened instantly, and he was stunned on the spot.

"What is it?" The other soldiers defending the city of the Annan Army, who had been resting in the shade, also returned to the city gate to look, however, like the Annan Army soldiers, their mouths opened wide in an instant.

"Yes, yes, that's the army of the Ming Dynasty!" Finally, an Annam Army soldier shouted.

"Oh no, the Ming Dynasty has invaded my Annan Kingdom, close the city gate!"

However, it was too late at this time, and the Ming army iron cavalry had already rushed to a place less than 100 meters away from the city gate, and the Ming soldiers who rushed to the front let go of the reins in their hands, raised the rifles in their hands, and pulled the trigger without hesitation.

"Bang Bang Bang"

A series of gunshots rang out, and the soldiers guarding the city gate of the Annan Army, who were shocked and had not yet fully reacted, were shot through the body by bullets.

"Poof!" The Annan Army soldier in the center was hit with a bloody hole in his forehead, and blood was sprinkled!

"Poof! Burst! Burst! Ah" The Annan soldiers next to him were not spared, and they were all killed on the spot.

"Rush!"

The Ming army's iron cavalry stepped on the corpse of the killed Annan Army soldier and rushed into the city of Lao Cai, and suddenly there was chaos in the city of Lao Cai, and gunfire broke out!

In just half an hour, all the more than 8,000 soldiers of the Annam Army in Lao Cai City were wiped out by the Ming army.
