At this time, Annam was not stable internally, and there were now two forces in Annam, one was the Northern Dynasty headed by the Zheng clan of Annam, and the other was the Southern Dynasty headed by the Nguyen clan of Annam, and the real emperor of Annam, Zhenzong of the Later Li Dynasty became a puppet in the hands of the Zheng clan.

As for Champong, it was overwhelmed by the Annan Nguyen clan, if it weren't for the threat of the Zheng clan of the Northern Dynasty, it is estimated that the Champa would have been destroyed by the Annam Nguyen clan.

In this case, Annan seems to be a soft persimmon, perhaps, it is better to start with Annan first.

Zhang Bin thought for a while, and then asked, "How is the strength of the Zheng clan and the Ruan clan in Annan?" ”

Zheng Zhilong reported in detail: "The troops under the Zheng clan of Annam and the Nguyen clan are less than 100,000, but they will all cast artillery, especially the Nguyen clan of the Southern Dynasty, they have long set up a cannon foundry with the assistance of Portuguese traders, and there are no less than hundreds of cannons cast over the years. Annan Zheng was forced to have no choice but to ask the Dutch for help, and later, they also set up a cannon foundry with the help of the Dutch, and there were no less than 100 artillery guns cast over the years. ”

When Zhang Bin heard this, he couldn't help frowning: "What kind of cannon are they casting, and what is the range?" ”

Zheng Zhilong then reported: "They cast the most old-fashioned Franc cannon and Hongyi cannon, of which Annam Nguyen cast Franc cannon with a range of about three miles, and Annam Zheng cast Hongyi cannon with a range of about four miles."

This is a bit troublesome, although the artillery cast by Annam Nguyen and Annam Zheng is not as good as the thousand-jin Franc cannon, but it is stronger than the Tiger Squat cannon, if you want to land and fight, you must carry enough thousand-pound Franc cannon, otherwise the infantry will suffer heavy casualties.

After listening to the report, Zhang Bin frowned and pondered, now it seems that the main purpose of conquering Nanyang is to conquer Donghu and Annan, Donghu is strong in troops and few firearms, and Annan is weak in troops and has many firearms, which side to fight first?

Zheng Zhilong saw Zhang Bin frowning and was silent, and couldn't help but suggest: "Shuangquan, why don't we send an envoy to Annan to order him to join the Ming Dynasty, Annan seems to be quite afraid of our Ming Dynasty after being beaten once by our Ming Dynasty during the Yongle period, as long as the envoy is sent forward, they will honestly attach themselves every time." ”

Zhang Bin naturally knew this, and he couldn't help but sigh: "Zhilong, Annan is aggressive, do you know? It doesn't make sense for them to call the ministers Nagong, they have reversed several times in the past 100 years, and each time they have made our southern border of the Ming Dynasty unpeaceful, so this time, we must restore the Jiaozhi Chengxuan Political Envoy Division, and directly put Annan under the rule of the Ming Dynasty, so as to ensure the long-term peace and stability of Nanyang. ”

When Zheng Zhilong heard this, he didn't say anything, this guy, it's a very simple thing to make them bow their heads and shout Da Ming boss, but it's a bit difficult to make everyone listen to you.

Zhang Bin pondered for a while, and finally ordered: "Yuan Kong, send an envoy to inform the Zheng clan of Annan and the Ruan clan of Annan, and let them come to surrender immediately, otherwise, when the king of the Ming Dynasty arrives, it will be when their heads fall to the ground." ”

When Song Yingsheng heard this, he hurriedly arched his hand and said, "The lower official obeys the order." ”

Zhang Bin still decided to try it first, after all, the price of coming to Wu is a bit big, and he doesn't want to let the elites of the Tianxiong Army and the Qin Army eat cannonballs.

Annan is indeed a little afraid of the Ming Dynasty, within a few days, the Zheng clan of Annam and the Annam Ruan clan have sent envoys to follow the clipper of the Nanyang Navy Division to Xingang City, they all expressed their willingness to pay tribute to the Ming Dynasty, as long as the Ming Dynasty gives them a king, the title that the Annam Zheng clan wants is the King of Ping, and the title that the Annam Ruan clan wants is the King of Quang Nam.

These guys, I'm afraid they are deliberately pretending to be confused, what Zhang Bin wants is to restore the Jiaozhi Chengxuan Political Envoy Department and bring Annan directly under the rule of the Ming Dynasty, but they still want to be the King of Freedom and the Emperor of the Soil!

It seemed that it would not work if he didn't do it, so he immediately gathered a hundred Weiyuan battleships, a hundred Zhenyuan cruisers and two hundred light ironclad ships, and took the Tianxiong Army and the Qin Army, as well as the envoys of the Zheng clan and the Ruan clan of Annam, and went straight to Haiphong Port, the largest port in Annam.

At this time, the Zheng clan of Annam and the Ruan clan of Annam were indeed a little afraid of the Ming Dynasty, but they did not want the Ming Dynasty to restore the political envoys of Jiaozhi Chengxuan, because then they would become the courtiers of the Ming Dynasty, rather than the emperor of the soil who dominated one side.

The reason why they all sent envoys to Xingang City to serve was to tell Zhang Bin that we should come according to the old rules and call the ministers a tribute, as for the resumption of Jiaozhi Cheng to announce the political envoy or something, then forget it, we are afraid of you, but it is not that we are too afraid to fight back, you will come.

More than 100 years of experience tells them that it is impossible for the Ming Dynasty to station a large army in Annam for a long time, because the cost is too great, the Ming court simply cannot afford it, so although the Ming Dynasty conquered Annam, but later the Ming Dynasty took the initiative to withdraw the 80,000 troops stationed in Annam, and the Ming Dynasty repeatedly threatened to use troops against Annam, but as long as Annam was willing to pay tribute, the Ming court accepted it.

They thought that the Ming court was coming to threaten them again this time, so they all asked for the title of king, but they were unwilling to restore the political envoy of Jiaozhi Cheng.

Zhang Bin didn't just threaten them, but also carried intimidation behind them, and if the intimidation didn't work, then he would really have to land and fight.

Within a few days, the fleet of the Daming Navy Division came to the largest Haiphong port in Annan, and as soon as the dense giant ships arrived, the defenders of Annan in Haiphong City were so frightened that their faces changed dramatically, joking, they only had a total of a few thousand people, how could they do hundreds of Daming giant ships.

Zhang Bin didn't care about their faces, and directly ordered a hundred Weiyuan battleships to fire five rounds of sideside salvo at Haiphong Port, and then five rounds of sideboard salvo at Haiphong City.

"Boom, boom, boom", with his order, the sea resounded with a terrifying roar of artillery, countless shells smashed like hail towards Haiphong Port, the port wharf and the ships parked in the port were instantly smashed sawdust, the defenders and the people in Haiphong City were frightened and fled in a hurry, and in less than half an hour, Haiphong City became an empty city.

Zhang Bin wanted this effect, he only wanted to intimidate at this time, and he didn't want to go to war, so he ordered the Weiyuan battleship to bombard the port first, scaring away all the defenders and civilians in the city.

The terrifying roar of artillery lasted for nearly half a day, and after ten rounds of broadside volleys, Haiphong Port and Haiphong City were in ruins, at this time, Zhang Bin ordered someone to call the messengers of Annan Zheng and Annan Nguyen to him, pointed to Haiphong Port and Haiphong City, and said: "Go back and tell your Zheng and Ruan Lords, if you don't surrender, this is the end." ”

This really frightened Annan Zheng and Annan Ruan, this Ming is too terrifying, it is ten thousand cannons at every turn, if the Ming Wang Shi really attacks, they will not be bombarded into powder!

They didn't know if the Ming Dynasty could pull tens of thousands of artillery pieces onto land, and if they could, they would be dead, so within a few days, the Zheng clan of Annam and the Ruan clan of Annam came to vote one after another, expressing their willingness to accept the jurisdiction of the Ming Empire and restore the political envoy of the Cheng Xuan of Jiaozhi.
