Zhu Youxiao naturally knew that the Jiaozhi Political Envoy was now Vietnam, which was abandoned by the Ming Dynasty during the Xuande period, but later in the Jiajing period, the Mo regime that was in charge of Annam at the time was attached to the Annam Metropolitan Envoy Division, but in fact it was not under the actual control of the Ming Dynasty, and could only be regarded as a fetter area.

However, today's Annan State is not dominated by the Mo clan, but is divided into three regimes that nominally exist at the same time: the Mo Dynasty, the Later Li Dynasty, and the Champa Dynasty, but in fact, the Later Li Dynasty is divided into the north and the south, Ruan Zhao and an independent Wu clan, a total of three secession regimes.

In short, the current Annan is in a state of fragmentation, and it is also the best time for the Ming Dynasty to rule Annan again.

Now, with the development of Daming's maritime trade, especially the development of the South China Sea, the geographical location of Annan has become particularly important, not to mention that there are also rich mineral resources in Annan.

Therefore, the reform of Annan and the return of the land, the eradication of the local separatist regime, and the re-establishment of the Jiaozhi Political Envoy Department are of extraordinary significance to the Ming Dynasty.

In addition, now that the Ming army, especially the army, has been dormant for a long time, it is time to try a knife to promote the further improvement of the Ming military strength in actual combat.

In addition, some newly developed guns and other unconventional weapons also need to be experienced in actual combat.

The note submitted by the Ministry of War clarified these contents and also made an estimate of military spending, but Zhu Youxiao did not immediately approve it directly, but said to Lu Xiangsheng: "What is the specific situation of Annan now, does Aiqing know?" ”

"Back to Your Majesty, since the abandonment of the Jiaozhi Bu Zheng Division, Annan was originally ruled by the Li Dynasty, but later the Mo family became bigger, Mo Dengyong forced the Li family to establish the Mo Dynasty, I Dynasty Jiajing period before the Li Dynasty general Zheng rebelled, from the new restoration of the Li Dynasty, the Mo family retreated to Gaoping, but the Zheng Ruan clan in the Later Li Dynasty did not agree, plus the former general Wu also supported the army and self-respect, thus causing the current situation of fragmentation."

After Lu Xiangsheng got up and answered, Zhu Youxiao nodded and said: "This is better, but it is not appropriate for my Ming Dynasty to directly move troops, one is that Annan is still the commander of my Ming capital, and the other is that once I am under pressure from the Ming Dynasty, it will inevitably make the regimes at all levels in Annan abandon their previous suspicions and work together to resist our Ming Dynasty; Although the Wu clan, Ruan Zhao and others are full of contradictions, they are all subordinate to the Later Li Dynasty as vassals, and the Mo clan is also willing to pay tribute to the Later Li Dynasty, which illustrates this point, so we have to think of a perfect strategy, that is, to control Annam, and not to let these separatist regimes unite against our Ming Dynasty. ”

"According to Weichen, since the Mo clan has attached to my Ming dynasty, my Ming dynasty should not recognize the power of the Li Dynasty, and send an order to the Mo clan to force it to quell the rebellion, and at the same time assist the Mo clan to destroy Li on the grounds that the Li Dynasty does not belong to my Ming Dynasty, so as to achieve the effect of helping the weak to win, and when the Zheng and Ruan clans of the Li Dynasty are wiped out, it is only easy to destroy the Wu clan and the Mo clan", Yang Sichang replied at this time.

Colonel Zhu You nodded, and replied: "That's it, send an order to the Ministry of War, immediately mobilize troops to the south, in the name of the exercise, Chen Bing, Liangguang and the area, the main force of the South China Sea Fleet returned to Hainan, and also entered the Beibu Gulf in the name of participating in this joint exercise, and transferred Yang Tinglin, the governor of Fusang, as the governor of Liangguang, and ordered him to command the exercise in the name of the left servant of the military department and the governor of Liangguang. ”

Zhu Youxiao gave this order, and the cabinet and the military department of the Ministry of Officials immediately began to operate.

However, at this time, the separatist regimes in various parts of Annam did not realize the imminent danger.

Just when the Zheng clan of the Later Li Dynasty was planning how to defeat the Ruan clan and then destroy the remnants of the Mo clan and the Wu clan, the Lu Jiayu division of the Fourth Army mobilized by the Ming army to attack the 100,000 army had already taken a large steam locomotive from the Huguang training site along the Xiangwu (from Xiangyang to Wuzhou) road south, and directly arrived in Wuzhou within half a month, and Chen Bingzhen Nanguan a month later.

At the same time, the South China Sea Fleet, which had been in Java and Sumatra, and even went to Australia to plunder the aborigines and establish colonies, was also concentrating on the Gulf of Tonkin one after another.

By the time Yang Tinglin was appointed governor of Liangguang, more than 120,000 people on land and sea had already been assembled.

At this time, Mo had also received the will of the Ming Dynasty to pacify the Li family, and before the Mo family could respond, Yang Tinglin, the governor of Liangguang, directly ordered Lu Jiayu's Fourth Army to go out of the town of Nanguan to attack An Shi on the grounds that the Mo family had sued the Li family for betraying the Ming Dynasty.

At the same time, the South China Sea Fleet directly bombarded Ha Tinh, the southernmost city in the area controlled by the Zheng clan of the Later Li Dynasty.

The Fourth Army was an ace unit in mountain warfare, and after entering the territory of Annan, it was not hindered by the miasma of Annan, and it took just three days to quickly penetrate the Laoling Pass in the important town of Anshi in the north.

At this time, Zheng Jie, the actual ruler of the Li Dynasty, also knew the news of the Ming Dynasty's large-scale attack, and hurriedly transferred his 50,000 imperial forest troops to guard Anshi Laoling Pass.

Zheng Jie, who originally intended to accumulate strength to conquer the Ruan regime in the south, had not experienced the defeat of Changde at this time, and he was considered to be a strong soldier, so in the face of the Ming Dynasty's attack, he did not surrender directly, but directly resisted.

The 1st Battalion of the 3rd Brigade of the vanguard of the Fourth Army was also not polite, and directly put 100 battalion artillery pieces away, and after two rounds of shells were fired, the entire Laoling Pass was turned into ruins in an instant.

And this Zheng Jie's 50,000 Imperial Forest Army was also directly stunned, tens of thousands of people died directly in the artillery fire, and then the Ming army rushed directly over, and the muskets in their hands crackled like cutting wheat grass to kill these Annan soldiers to the ground.

In less than half an hour, in front of the Ming army of only 3,000 people, the 50,000 imperial forest army completely collapsed, and the Ming easily entered and occupied Laoling Pass.

Then, the Fourth Army directly divided its troops to the south and occupied the cities of Yezhou, Western Capital, Chi Hoa, and Cao Binh, while at the same time, the Nguyen Thi also took the opportunity to fall into the well and directly occupy Changde.

In less than a month, Zheng Jie committed suicide by jumping directly into the lake, and at the same time, the Nguyen army occupying Changde was completely annihilated by the marines of the Daming South China Sea Fleet before they could withdraw.

The Fourth Army of the Ming Army directly occupied the southern part of Annam controlled by the Ruan clan with lightning speed, and when the Ming Dynasty was ready to wave troops to seize the power of the Wu clan, the Wu clan saw that the general trend had gone and surrendered directly, and the Mo clan also took the initiative to give up the privilege of Yongzhen Annam.

At the same time, the South China Sea Fleet directly bombarded the city and occupied the entire territory of the city in two days.

The army of Annan was completely unable to pose any challenge to the Ming army, and the only challenge was these remnants of the guerrilla forces.

However, under the temptation of artillery, incendiary bombs, poison gas bombs, money, and land division, these guerrilla forces did not pose much challenge to the Ming rule of Annam.

In total, it took more than three months, and the Ming Dynasty directly pacified Annan, and reinstated the Jiaozhi Political Division, which had been abandoned for a hundred years.

Lu Jiayu was transferred from the governor of Guangdong to the governor of Jiaozhi and supervised the military affairs of Jiaozhi, while Zhang Huangyan was transferred from the north to the south to be the political envoy of Jiaozhi Zuobu, responsible for the civil affairs of the Jiaozhi Buzheng Division.
