Zhou Cao captured Liangshan and other cities with lightning speed, and after opening the gate of the Red River Plain, he was not in a hurry to attack, rested in Liangshan City, and waited for the garrison behind to arrive to take over the defense, this time may take two days, and Zhou Cao will lead the army into the Red River Plain two days later, and the troops will be under the city of Hanoi.

When the Ming army was resting in Liangshan City, the king of Annam, who was in Hanoi, finally received the news of the invasion of the Ming army, and learned that the Ming army had captured Liangshan City, the door of Hanoi was wide open, and the heavy troops of the Ming army could appear under the city of Hanoi at any time, and he was suddenly frightened stupid by this terrible news.

"How is that possible! How is this possible! King Annan was furious.

He couldn't believe it at all, how could the Ming army suddenly enter the country of Annan without warning?

He knew the strength of the Ming Dynasty, and it was when the Ming Mansion was about to fall, the king was in trouble, the new emperor was not established, and there was chaos, he dared to send troops to capture several small county towns in the Ming Dynasty, but as soon as the new emperor of the Ming Dynasty was established, he immediately retreated in fear.

There is no way, he has a small population in Annan, and even if the Ming Dynasty is about to collapse, there are still several provinces in the south of the Yangtze River, with a population of tens of millions, and the national strength is still much stronger than his Annan.

From Qin Shi Huang to the Song Dynasty, for more than 1,000 years, the Annan Kingdom was under the direct jurisdiction of the Central Plains Dynasty, even if the Song Dynasty became self-reliant, it was also a subject country of the Central Plains Dynasty for all dynasties, and the reverence for the Central Plains Dynasty was deeply rooted in the bone marrow.

King Annan is an ambitious person, the Central Plains is prosperous, the land is vast, he dreams of a piece of the pie, which is why he sent troops to take advantage of the fire to rob whenever he has the opportunity.

He only occupied a few inconsequential small counties of the Ming Dynasty on the spot, and the Ming Dynasty set up a new emperor and regained the court, in order to prevent the Ming from diverting attention to his Annan Kingdom, he immediately stopped the attack and withdrew most of his troops.

He knew very well that unless the Ming Dynasty was in chaos again, he would have a chance in Annan, so after he withdrew his troops, he planned to sit on the mountain and watch the tiger fight, and when the Ming Dynasty was chaotic again and had no time to look south, he would send troops to capture several cities of the Ming Dynasty and expand the territory of Annan.

It's just that what makes him extremely regrettable is that after the new emperor of the Ming Dynasty was re-established, he gradually became stable and strong, first won the first decisive battle with the Manchu Tartars in Xuzhou, and further stabilized the political situation of the Ming Dynasty in the south of the Yangtze River, and then less than four years, the Ming Dynasty successively pacified Li Zicheng, Zhang Xianzhong and other civil strife, and then the Northern Expedition, drove away the Manchu Tartars, and the Ming Dynasty regained unification.

Although the king of Annan was unwilling, he also knew that it was impossible, so he did not pay attention to the Ming Dynasty again, but he never had the intention of returning the county towns of the Ming Dynasty.

According to his thoughts, Daming has a lot of resources and many cities, and he definitely doesn't care about those few inconsequential small counties, maybe Daming has just ended decades of war, and if he wants to recuperate, he will give up those inconsequential small counties in order to appease him Annanguo, even if Daming does not intend to appease him Annanguo, he will at least issue an order to blame him first, and let him Annanguo take the initiative to return, instead of directly using swords.

More than two months ago, it was not that there were no Ming officials who secretly sent a letter to warn King Yu Annan, hoping that he could take the initiative to return those small county towns, but he did not take it to heart, and only insisted that Daming did not issue an order to reproach and order, and it would be fine.

Even if he heard about the Ming Dynasty's dispatch of troops to North Korea, he didn't care much about it, and he still thought about it.

After all, he thinks that the Ming is attacking North Korea, the Ming is strong, but defeating North Korea is not an overnight thing, even if the Ming Dynasty defeats North Korea in the end, but the Ming Dynasty has experienced decades of war, and the loss of attacking North Korea is bound to be not a vegetarian, and he is not a vegetarian in Annan, there are still hundreds of thousands of troops, and under the full conscription, 300,000 troops are not a problem, he still firmly believes that the Ming Dynasty will not easily move troops against his Annan country, and refuses to spit out what has been eaten in his mouth.

However, what he didn't expect was that the Ming Dynasty sent troops without warning, and in just one day, he captured Lao Cai, Gao Ping, Liangshan and other important towns in the north, breaking the road to attack Hanoi in one fell swoop.

One day, even if the gates of the three important towns were wide open, and the Ming army kept running, the Ming army would not be able to run such a long distance on its two legs.

Although according to the report of the spies, the Ming army carried a large number of war horses, and it was likely that they formed an iron cavalry, but Laojie, Liangshan and other important northern towns together had more than 30,000 troops to defend them, and the Ming army was not allowed to attack unless 200,000 cavalry came to attack, but even so, it should not break the three cities so quickly, this is too amazing, too unbelievable, this is the main reason for his fear.

"Da Ming dared to fight on two fronts, and without warning, he sent troops to my Annan country, damn it!" An Nanguo's face was extremely ugly and he gritted his teeth.

Annam is located in a remote area, and the news of the destruction of Korea has not yet reached here, so the king of Annam does not know the news that Korea has been destroyed, so he thinks that the Ming army is fighting on two fronts.

The enemy situation was unknown, and the king of Annam could not predict how powerful the Ming army would be.

"No matter what, I can't sit still!" King Annan said with a hideous face.

Immediately, Annan took advantage of the Ming army's rest in Liangshan City, and quickly gathered almost the entire elite army of Annam to deploy on the front line of Hanoi, preparing to fight the Ming army under Hanoi City!

Attacking Annan, the Ming Dynasty did not leave enough time for Annan to recruit strong men from all over the country, so the king of Annan could gather less than 140,000 troops.

Nearly 140,000 troops, among which there is the pride of Annan, the vine armor soldiers! This is also a big force, so King Annan is not without the confidence to repel the Ming army.

On September 1, the 60,000 garrison of the Ming Dynasty also arrived in Liangshan City.

Because it was a garrison army and was directly under the command of Zhou Cao, there was no army commander, and a division commander surnamed Wu assisted in command.

"Master Wu, the protection of Liangshan and other cities will be taught to you!" Zhou Cao said with a smile to the commander of the garrison, Wu.

"Please rest assured, Commander Zhou, my garrison will ensure that the rear is foolproof!" Master Wu said.

Zhou Cao nodded and didn't say anything more.

After the garrison fully took over the protection of Laojie, Liangshan and other cities captured by the Second Army, Zhou Cao gathered 20,000 troops of the Second Army and attacked Hanoi, the capital of Annan, in a fierce manner, preparing to destroy Annan in one fell swoop.

"Drive!"

"Boom"

Although the iron cavalry did not gallop at full speed, but in the end it was four legs, much faster than two legs, just one day, the next morning, 20,000 Ming Army Second Army Iron Cavalry under the command of the commander Zhou Cao under the command of the army commander Zhou Cao under the city of Hanoi!

A decisive battle that will determine the survival of the kingdom of Annam is about to begin!
