Annam, the capital of Thang Long (Hanoi).

In the palace, in Gaochang City, in the palace, the slightly tired Qing King Zheng Jie was discussing things with his subordinate ministers.

After Zheng Zhu drove the Mo Dynasty out of Yuebei from his ancestors, he welcomed Emperor Li into Thang Long, and the Li Dynasty was able to prosper, but Zheng Zhu Zhongxing Li Dynasty rebuilt the hero himself, arrogant and arrogant even more than before, and repeatedly abolished several generations of emperors.

Lord Zheng not only blurred the six ministries set up by the emperor of the Li Dynasty, but also incorporated the six ministries into the "six times" in the Zheng Dynasty's mansion, forming a system of "if you don't take the country, you will seize the country, and if you don't call the emperor, you will be like the emperor".

The current Zheng Zhu, Zheng Jie, sits side by side with Emperor Li directly on the left side of the palace throne, and the etiquette of his subordinates such as entering the court and worshipping and playing names has long ceased to exist.

In the face of Daming's summons, the dying Zheng Jie was indignant, and secretly said I am almost eighty years old, how can I go on a long journey to Nanjing to ask for guilt?

Didn't the Ming Emperor want to kill me? Don't go, say nothing and don't go!

Looking at his father's expressionless old face, Zheng Zheng, the young master of the Zheng family, said cautiously: "Father, according to our report, the Ming army has sworn from Yunnan and is coming to my Annan. ”

Zheng Zheng had a worried look on his face and continued: "Although there are not many people from the Ming Dynasty this time, the Ming army has outstanding combat strength, and we are probably not their opponents......

Zheng Jian smiled and said: "Wang'er, don't worry so much, Emperor Zhu Ming is just scaring us, he is doing it for their people!" ”

The old thing coughed a few times, and his face was filled with a slight smile: "When Chongzhen was fifteen years old, my father went to Beijing to see the Ming Dynasty, but didn't you see it, their so-called rich Gyeonggi Shandong area, the city is depressed, how sparsely populated, and there are thieves and soldiers everywhere!" ”

Zheng Zheng was stunned, and couldn't help reminding: "Father, it's been twelve years of Tianwu, and Daming has already recovered its strength!" ”

Zheng Jie waved his hand and said: "It's only more than ten years, what kind of development can they become, besides, the Ming Kingdom has been fighting for many years, fighting the Qing Dynasty, sweeping Mongolia, and also expeditioning to the Western Regions, and a few years ago they crossed the sea to fight Japan, their national strength is consumed too quickly, even if they don't die, how can they still invade my Annan on a large scale?" ”

Zheng Zheng was speechless, and suddenly felt that his old father was demented......

He looked at the ministers of the court, and immediately someone understood, and stood up and persuaded: "King, there is a folk song circulating in Thang Long these days: Annan soldiers and horses are like frost and snow, Han soldiers and horses are like the sun and moon, the sun and the moon shine on the frost and snow, look back and destroy the ......"

This folk song was sung widely throughout Annan, which made the people of Annan panic for a while, and Rao is officials sent people to find out who the three nursery rhymes were, but nothing was found.

Hearing this, Zheng Jie only raised his head slightly, and did not speak, he knew that it must be the Jinyi guard of the Ming Kingdom who was stealing rumors and breaking the hearts of the people of Annan.

Seeing that he didn't react, the minister hesitated for a moment and said: "Your Majesty, Emperor Ming said in the edict that as long as the King repents and asks the Ming Court for his guilt, Emperor Ming will not blame the past, and for the sake of the millions of people in Annan, you have to think twice......."

"Presumptuous!"

Zheng Jie was furious and shouted, "Do you want me to die?" In that case, then you should die first! ”

Zheng Jie roared: "Come on, punish this rebel to death!" ”

Pity this iron-clad minister of Annan, who spoke for the country, was trampled to death by an elephant......

The prince Zheng Zheng couldn't figure it out, the Ming army was about to hit the doorstep, why was his father still so confident?

For the sake of the Zheng family, Zheng Zheng decided to admonish to the end: "Father, my Annan population is only a few million, the soldiers are only 100,000, and the financial resources are not comparable to a province of the Ming Dynasty, how can I fight against the Ming Dynasty!"

Li Weiqi, the Li Emperor on the side, raised his head slightly when he heard this, and then lowered his head again, as if dozing off.

Zheng Jie stood up with the throne, pointed to the prince and said: "I have 100,000 soldiers, and the Ming army is only a few thousand, what can I do?" ”

Zheng Zheng saw that his father was still like this, he was anxious, but he had nothing to do, so he had to repeatedly state the pros and cons in front of Zheng Jie.

The old man is still very healthy, Zheng Jie laughed three times, and said: "I have the two passes of Kuaiyi and Jiling in the north and south of An, and there are four rivers of Xuan, Tao, Cang and Fuliang as risks, my army has set up fences along the north and south banks of the river, the ships are concentrated in the river, and the city gate bridge ships are connected up to 900 miles, and our army is stuck to the danger, that is, the Ming army has millions of people, and they cannot be overcome, and they are tired and return!" ”

Zheng Jie raised his hand at four points as he spoke, quite the courage to point out the country when he was young.

Finished!

After watching his father's on-the-spot performance, Zheng Zheng's heart suddenly cooled down.

He likes to read newspapers, and he deeply feels the strength of the Ming Dynasty and the strength of the Ming army, even if Annan has 100,000 armor, it is not necessarily the opponent of thousands of Ming troops.

He did not know what the Ming army would look like when Annam arrived, when the people were in ruins, and the city of Thang Long and other cities, which had become increasingly prosperous, might be in ruins.......

On 13 May, Li Dingguo commanded his troops, marched from Pingxiang, crossed the Polei Pass, and paid homage to Langshan Mountain in Annam, and issued a list of 18 charges against Zheng Jie.

Since ancient times, Lang Son has not only been a transportation hub in northern Vietnam, but also a barrier gateway to Hanoi, the capital of Vietnam.

Surrounded by a series of high grounds, the terrain is very steep, and if you want to use troops in the north of Vietnam, Lang Son is the key to it.

Since ancient times, the Central Plains Dynasty took Jiaozhi in the south, and here is the place where it must pass, and then it can be determined.

Defend Lang Son to block the enemy in the mountains of northern Vietnam; Take Lang Son, you can take Hanoi directly!

Obviously, Annan's army did not have such skills.

Li Dingguo led the army to easily connect the two passes of Ke Kuai and Jiling, took the Qinzhan station, shot away the ambush soldiers of Annan, and drove straight to Xinfu.

At this time, the Mo army who came to rush to the field also came from Gaoping and camped in Baihe, hoping to drink soup.

Li Dingguo ignored the Mo army and ordered to move from Xinfu to Sandaizhou to obtain ships from Guangxi.

As Zheng Zhu Zheng Jie, said, there are many rivers in Annan, and the Annan army can be deployed along the river, and the Ming army can be fatigued and eventually dragged down by the Ming army!

Obviously, Li Dingguo did not accept this set, and after obtaining the ships, he advanced the army to the north of the Fuliang River and camped, and sent Mu Tianbo, the Duke of Qianguo, to send troops to the Jialin River to break the enemy army, pretending to march elsewhere to paralyze the Annan army.

On 18 May, Li Dingguo personally led a large army across the Fuliang River, broke through the villages of Choojiang, Trapmei, Wanjiao, and Pulai, demolished their wooden fences along the river, and captured and beheaded countless Annan troops.

What slaps him in the face is that Zheng Zhu confidently said that "the 900-mile four-river defense line that the Ming army can't conquer even a million people" was broken through by the Ming army in only three days!

In this battle, the Ming army killed three Zheng generals and beheaded more than 28,000 Annan troops!

On May 20, the Ming army then conquered Dongchao, Langjiang and other prefectures, and defeated the naval division of the Annan army at the Mumaru River, beheaded 13,000 ranks, captured more than 120 generals, and drowned countless Annan troops.

Li Dingguo ordered Mo Jingyu to appease the officials and the people and the followers, and he continued to lead the Ming army south, pointing at Shenglong, the capital of Annan!

The Mo Dynasty ruled in Annam for decades, and it still has a bit of a background, and after Mo Jingyu's careful wooing and strong publicity, tens of thousands of Annan people came to return to Shun every day.

From the southern border of the Ming Dynasty to the capital of Annan Shenglong, but the distance of 300 miles, Li Dingguo led 5,000 Ming troops like a bamboo, and it took only ten days to advance more than 200 miles, killing tens of thousands of Annan troops all the way, so that the enemy was terrified, and no one dared to engage in battle!
