"Your General Staff is ready to be stationed in the Indochina Peninsula?" Li Xuanqing took the plan handed over by Xu Tianxiang in his hand, looked at it and asked. Because of Li Xuanqing's habitual problems, many later generations of the name of the surrounding areas of the Tang Dynasty began to gradually spread among the Tiance Army, the Indochina Peninsula is one of them, and even Manraka, which has been incorporated into the overseas territory of the empire, has recently been discussing whether to change its name, but Li Xuanqing didn't care about this, after all, unlike other regions, the name Manraka is actually very famous in later generations, basically as long as you say it, you can know it. What really surprised Li Xuanqing was that the general staff's plan for the Indochina Peninsula proposed at this time seemed to be just a loophole in the fact that there was no war in the northwest for the time being, but after thinking about it carefully, I am afraid that it was also an idea of supporting the northwest from the sea. Once the Indochina Peninsula is taken, the entire southern sea will be under the control of the Empire, and a large area of islands and seas will be directly incorporated into the Empire's territory, which is also to reduce the pressure on the northwest from a strategic level, and can concentrate most of the Empire's resources and energy into the northwest. From a tactical point of view, after the Indochina Peninsula is captured, the navy will be able to go all out to pass through the South and Western Oceans, and the Tang fleet and the Western Fleet will be able to follow the road opened up before and directly reach the hinterland of the Great Food Empire, and judging from the current map explored by Xuan Yingwei, many territories of the Great Food Empire can even be included in the range of naval firepower. This is not a major threat to the big cannibals who have already seen the majestic posture of the Tang Dynasty ironclad battleships.

For the problem of how difficult it is to solve the remaining indigenous forces on the Indochina Peninsula, whether it is Li Xuanqing or Xu Tianxiang or Wang Houchun, who is in charge of the war department, does not care, not to mention that these places have been the vassals of the Central Plains Dynasty in the southwest since the time of Emperor Wu, even now the infiltration of these forces has determined that basically as long as there is a corps of troops starting from southern Yunnan and Jiaozhou, all the way to the south and sweeping directly. Therefore, Li Xuanqing directly signed and approved the plan without specifically looking at the general staff, and with Xu Tianxiang's caution, he was not sure enough that he would not report it to him at all.

Li Xuanqing didn't look at it, Xu Tianxiang simply said the deployment, "The General Staff intends to let Tianyi lead the army from southern Yunnan to attack along the road of Chen Yu's attack on Nanzhao from Jiaozhou to the south, all the way to sweep the Queen's Kingdom, Luo Bodi and Banban, and then join the marines in Jiaozhou to attack the Angkor Dynasty and completely wipe out the largest local force in Central and Southern China." As for the Shan and Huren in the southern part of Nanzhao, as well as Bagan and the southern tip of the Huren Kingdom that were scattered by us, and the Bago Kingdom, which had been cleaned up by the marines once before, waited until after the Angkor Dynasty was captured, Tianyi led the main army to move over and take them one by one. The southern end, including the long peninsula connecting Manchuria, would be left to the Marines, who would be within the reach of the navy. ”

Li Xuanqing had no opinion on such a deployment, and after thinking about it, he suddenly asked: "The navy has been reequipped with combat equipment in some tropical rainforest areas since a few years ago, has it used a report to send it to the General Staff Headquarters?" ”

"Yes, not only in terms of weapons and equipment, but also in terms of our soldiers' equipment, including military uniforms, etc., there are reports and suggestions, and even there is a summary of the basic tactics of fighting in the tropical rainforest area, plus the report written by Chen Yu that year, the General Staff has transferred all of them to Tianyi, and they will be equipped with new equipment and special medical personnel and equipment before they go out." Xu Tianxiang nodded and said: "The General Staff Department and the Ministry of National Defense are ready to use the 19th Corps of Tianyi and the Marine Corps as a template on the basis of this battle to form a full-time combat unit in the tropical rainforest, which is the same as the mountain battalion, specializing in tropical operations. ”

"In that case, let's order the preparations." After Li Xuanqing nodded, the General Staff was also rapidly conveying orders, and Li Tianyi's 19th Corps, which was waiting in the vicinity of Guangzhou, also received orders later, as well as a large number of new equipment transported by the logistics department with the ship. It includes specially developed improved rifles, tropical military uniforms, food supplies, and lightweight mountain guns improved in combination with mortar styles, which are convenient for use in areas where tropical redundant roads are inconvenient. In fact, these special equipment are not concepts brought by Li Xuanqing from later generations, but concepts that Guo Chongtao and Chen Yu have come up with before, and after the Marine Corps conquered overseas strongholds, especially Manraka and Nanyang regions, these were gradually transformed into physical objects and formed a system.

After a little refurbishment and adaptation to the new weapons and equipment in his hands, Li Tianyi also received a report from the Marine Corps that had been prepared. The 19th Corps also began to immediately take a train from Guangzhou into southern Yunnan and then began to travel to Wendan City in southern Yunnan, from where it was the first to enter the Queen's border. Although Wendan City is a border city in southern Yunnan, but now after the development of trade with other indigenous forces in central and southern China, this former inconspicuous small city has gradually expanded its scale, although most of them are local indigenous people, but the sinicization of the Han people sometimes does not need so many steps, the power of assimilation is huge, the education of popularizing Chinese characters and Tang dialect in southern Yunnan has gradually opened, and a new generation of children has gradually abandoned the dialect of their ancestors and accepted the advanced civilization that came from the Central Plains. After all, the Ministry of Education and the Ministry of Civil Affairs stuck all the government proclamations and administrative officials who demanded that it was enough for Tang Yan to write Chinese characters, so that all the border tribes began to actively and seriously integrate into the big collective of the Tang Dynasty.

However, after the soldiers of the 19th Corps suddenly drove to Wendan City and then continued south into the border of the Queen's Kingdom, this indigenous force that had been attacked by Nanzhao many times in the past but ended in failure felt the danger of being overpowered by Mount Tai this time, and the reason why the Queen's Kingdom was so called by the Central Plains Dynasty was that its domestic rulers were mainly women. For this reason, this time, the queen ran south from the capital of the country, gathered the army and immediately went north, and at the same time personally sent a letter to Li Tianyi, asking why the Tang Dynasty sent a large army to the south, and whether it was dissatisfied with the queen's state.

Li Tianyi ignored this kind of thing at all, and on the one hand, he led the army to continue to advance and directly rushed to the northern basin of Myanmar to confront the main force of the Queen's State, and on the other hand, he asked the accompanying officials of the Ministry of Foreign Affairs to hand over Li Xuanqing's edict to the envoy of the Queen's State, asking the other party to be ready to return to the Tang Dynasty, and those who dared to resist the edict of the Celestial Empire would be exterminated by force. And Li Xuanqing's edict is even more simple and clear, the tribal forces in the central and southern regions have been the vassals of the Central Plains since the era of Emperor Xiaowu of the Han Dynasty, and all dynasties have the tradition of paying tribute to the Central Plains. If they failed to obey the edicts of the Tang Dynasty, the Tiance army would use force to conquer the vassals and settle the old accounts of the Central and Southern regions that had violated the orders of the Central Plains since the time of Emperor Wu.

This tough edict and the strong actions of the 19th Corps made the strength of the queen kingdom quickly divide, and some of them have always been in awe of the Central Plains culture, and the forces of the queen state who have seen the prosperity of the Central Plains over the years have begun to seriously examine the benefits of Li Xuanqing's edict for the queen kingdom. However, most of the strata were unwilling to give up their centuries-old regime and rule, and called on the people of China to fight against the Tang Dynasty together with the example of several previous victories against the Nanzhao invasion. At the same time, the envoys of the Queen's Kingdom also began to quickly move towards the surrounding powers, hoping to mobilize them to help the Queen's Kingdom.

However, Li Tianyi didn't know this, after replacing the special equipment in the tropical rainforest area and seconding more than 100 staff officers and grassroots generals who were proficient in the tactics of tropical rainforest operations from the Marine Corps, the 19th Corps has been able to deal well with the rugged roads along the way and the rivers and harbors that appear from time to time. With these guarantees, Li Tianyi immediately sent troops to attack the position of the queen after seeing that the queen state ignored the edict issued by the Ministry of Foreign Affairs, and grabbed the entrance to the northern Burma basin with great strength. In this way, the Queen's vain attempt to stop the Tiance army in the northern Burma basin quickly failed, and a major battle ensued near Nanben. The 19th Corps, under the leadership of Li Tianyi, relied on mountain artillery and machine guns to break through the opponent's attack formation, killed the opponent's commander in a battle, and captured the queen who was supervising the battle in front and preparing to repeat the old trick and wanted to shoot the soldiers of the Tiance Army with medicinal arrows. At this point, the defense of the queen kingdom quickly collapsed, and the 19th Corps entered the capital of the queen of Nanben on May 28, the ninth year of the Apocalypse, and captured all the high-ranking officials inside.

After taking the Queen's Kingdom, Li Tian personally sat in Nanben to suppress the local rebellion, and on the other hand, he ordered the forward troops to attack the northern part of the Angkor Dynasty to the east, and fought a major battle near the border with the troops who came to the aid of the Queen. At this time, the Marines also gathered 10,000 men near Yanzhou in Jiaozhou Province, and then crossed Jiaozhou and began to move towards Angkor Thom, the ruling center of the Angkor Dynasty. Compared with the 19th Corps, which had to wait for the National Guard and civil affairs officials in the rear to take over the follow-up government affairs of the Queen's Kingdom, the Marines were blessed with the backing of Jiaozhou Province, not only destroying all the way along the way, but even encountering the opponent's elite troops, War Elephant Cavalry, when they arrived more than 100 miles east of Angkor Thom. The more than 10,000 marines relied on artillery and muskets to break up the opponent's 50,000 war elephants, cavalry and infantry, and those war elephants who were frightened and fled became the best helpers of the marines in the panic. From the very beginning, the war elephants, a heavy force that had been invincible in previous wars in Indochina, suffered a devastating blow. Coincidentally, in early June, after Li Tianyi led the main force and the forward troops to converge, they also encountered the opponent's war elephant troops here in the process of going south. Unlike the Marine Corps, which was not equipped with machine guns, the death blockade composed of mountain artillery and machine guns did not give these behemoths the slightest chance, and more than 10,000 war elephants were almost all killed on the spot during the war, so that the soldiers of the 19th Corps ate meat for more than half a month after the war. The terrifying firepower of the Tiance army in these two battles made the main force of the Angkor Dynasty, which had already become strong and had already revealed the power of a powerful country, be quickly defeated. In the following half a month, neither the Marines who had attacked the vicinity of the royal capital nor the 19th Corps from the north to the south encountered any major battles, and swept all the way, and the two armies merged in Angkor Thom on June 15, the ninth year of the Apocalypse, and the entire Indochina Peninsula had entered the hottest time of the year. In the following days, Jayavarman III of the Angkor Dynasty in the city sent people out of the city to negotiate with Li Tianyi, willing to surrender to the Tang Dynasty and cancel the title of Angkor Dynasty. However, Li Tianyi did not agree to this practice of only surrendering to sincerity and not offering the city, and made it clear that all the lands of the Angkor Dynasty would be included in the territory of the Tang Dynasty from this moment on. Jayavarman III and his family were supposed to travel to Chang'an to meet the Tang Emperor and ask for pardon. This assertive attitude was unacceptable to Jayavarman III, but after the 19th Corps ordered artillery to bombard the city of Angkor Thom, the roaring cannons began to make everyone in the city recognize the great strength of the Celestial Empire. Therefore, on June 21, the ninth year of the Apocalypse, the last forces of the Angkor Dynasty laid down their arms, and Angkor City was immediately occupied by the Tiance Army, and Jayavarman III and all members of his family were subsequently controlled by the 19th Corps and sent to Chang'an. However, Li Tianyi also made it clear to the remaining vassals of the Angkor Dynasty that as long as Jayavarman III did not sin against the Tang Emperor in Chang'an, the Tang Dynasty would not control their freedom in life, and they would be free to travel anywhere in the near future. This statement also made the Angkor Dynasty slightly less hostile to the arrival of the Tiance Army.

The 19th Corps handed over all this place to the marines after a short rest in Angkor Thom, because the Angkor Dynasty bordered Jiaozhou, so this time it could directly mobilize a large number of civil officials and the National Guard from Jiaozhou to station, and the National Guard would not leave this place for a while, so Li Tianyi led the army to set off again at the end of June of the ninth year of the Apocalypse and returned to Shanbu and other places bordering Nanzhao in the west, preparing to take the last obstacle to the reunification of the Indochina Peninsula.

However, at this time, the Tiance army attacked the southern peninsula in these major battles have made all the tribes of the entire peninsula shudder, and the behemoth of the Central Plains has wiped out the two most powerful kingdoms on the entire peninsula at the beginning, which makes the remaining Shan, Huren and Bagan and the former Mino's alien races not know what to do at all. And in addition to Shan, these places are basically more and more affected by the increasingly huge Western trade of Xihai County in Nanzhao, and the backward economic outlook of their own country has no resistance in the face of the strong economy of the Tang Dynasty, and it has been quickly assimilated. Thanks to the advantages of a large number of natural minerals, especially gold and silver mines, although the economy is backward, the people in these places are not poor, so they are more and more dependent on the consumption of Datang commodities. At this time, hearing that the Tang Dynasty was making a big move against the Indochina Peninsula, these local forces were panicking, and at the same time, some people were also thinking about whether they could also benefit from the prosperity brought by the other party's economic development after returning to the Tang Dynasty.

This mentality was shown to the extreme when Li Tianyi's soldiers were in the Shan Tribe, almost at the same time that Li Tianyi was fighting against the harsh natural environment of the Shan Province while sending troops to continuously attack the few armies in the Shan Province, the Huren Kingdom had already begun a coup d'état, and some nobles who fell to the Tang Dynasty quickly overthrew the existing regime with the support of Xuan Yingwei and then surrendered to the Tang Dynasty. In this way, the ordinary Shan tribe did not hesitate after seeing that his neighbor actually surrendered directly, and accepted the edict brought by Li Tianyi before the formation, and handed over the control of the country to the Tiance army. In this way, the entire Indochina Peninsula, which was left with Bagan and Bago alone, had no way to hold back the iron hooves of the 19th Corps. At the end of July of the ninth year of the Apocalypse, when a battalion of the 19th Corps captured the capital of Bago, the entire Southwest Campaign came to an end, and the territory of the huge Indochina Peninsula entered the official territory of the Tang Dynasty.
