In addition to the prosperity of business and the prosperity of the people, Emperor Xuanzong of Tang Dynasty was also reflected in the use of foreign troops.

Emperor Xuanzong of Tang was very happy with merits. Although he was tired of politics, he always paid attention to border wars and praised victory. He almost never compromised with the countries that dared to provoke the Tang Dynasty. He could only go to war, and even multi-line wars.

Because Emperor Xuanzong of Tang was warlike, the governors on the frontier of the Tang Dynasty tried to cater to Emperor Xuanzong of Tang and gain fame for their own future, so they repeatedly made excuses to go to war with neighboring countries.

In the sixth year of Tianbao, the princess of Tubo married King Xiaobolu as his wife, so that the Xiaobolu and more than 20 surrounding countries collectively rebeled into the Tang Dynasty and defected to Tubo.

The Tang Dynasty and Tubo were old enemies. After Emperor Taizong of Tang Dynasty, Princess Wencheng, entered Tibet, the Tubo Kingdom was in vain for fifty years.

However, Tubo was also in the most powerful period in its history. How could he be willing to return to the Tang Dynasty? He has been competing with the Tang Dynasty since the Wu Zetian period, and never gave up even if it failed repeatedly. This incident of Xiaobolu Kingdom was another attempt by Tubo Kingdom to compete for hegemony between the Tang Dynasty.

For a powerful emperor like Emperor Xuanzong of Tang, any betrayal cannot be tolerated, because of the incident of Xiaobolu Kingdom, the first war against the Tubo Kingdom began after the Tang Dynasty entered the Tianbao Year.

Under the order of Emperor Xuanzong of Tang, Gao Xianzhi, deputy governor of the four towns of Anxi, led more than 10,000 troops to conquer the Xiaobo country in the seventh year of Tianbao, and fought against the Tubo and Xiaobo country coalition forces at the Yulianyunbao.

In the first battle, the Tang army killed Tubo, and the Xiaobolu coalition army was 5,000 heads, and more than a thousand were captured.

After two months of war, Gao Xianzhi defeated Xiao Bolu Kingdom and captured King Xiao Bolu and Princess Tubo.

With his military achievements, Gao Xianzhi was promoted to the governor of the Four Towns of Anxi.

The governor of the Tang Dynasty had great power, so he could mobilize the troops under his jurisdiction without using military power. He also had the right to conscription and tax on his own, and he could also judge the war against the surrounding countries on his own.

In the battle of Xiaobolu Kingdom, the Tubo Kingdom was defeated in a crushing defeat. Even the princess who married was captured by the Tang Dynasty. The request failed. The emperor of the Tubo Kingdom was very angry. How could he give up? Since the end of the seventh year of Tianbao, he has repeatedly provoked the Tang Dynasty.

Emperor Xuanzong of Tang was furious. In order to teach the arrogance of the Tubo Kingdom, in the eighth year of Tianbao, he ordered the Longyou Jiedushi Geshuhan as the commander, to command Longyou, Hexi, Tuju Abus' army, Shuofang and Hedong, to fight back against Tubo, and started the second battle with the Tubo Kingdom after the Tianbao year.

The scale of this battle was much larger than that of the Battle of Xiaobolu Kingdom. Both sides dispatched tens of thousands of troops, fighting fiercely for months, winning and losing each other. The main reason was that the Tang Dynasty had the upper hand and the Tubo Kingdom was passively defending.

Geshuhan led the Tang army to fight against the Tubo Kingdom fiercely. Gao Xianzhi, who had just become the governor of the four towns of Anxi, was not willing to be lonely.

In the ninth year of Tianbao, Gao Xianzhi pretended to be in trouble with the hostile Shi Kingdom on his face, lowered the Shi Kingdom's vigilance, but secretly plotted to lead his army to attack Shi Kingdom.

The Shi Kingdom is located southwest of Balgashi Lake and more than 400 miles south of Henglus. Its national strength is only stronger than that of Xiaobolu Kingdom. It was originally suppressed and beaten by Anxi Si. When he relaxed his vigilance, he was sneak attacked by Gao Xianzhi. How could he resist it?

Under Gao Xianzhi's leadership, the Tang army broke through in one fell swoop. The king of Shi Kingdom was captured, the prince of Shi Kingdom fled, and fiercely resisted the Tang army with the remnants of Shi Kingdom. However, facing Gao Xianzhi's Tang army's attack, it was sooner or later that the country was destroyed.

Fierce battles in Longyou in the Middle East, and the Nanzhao Kingdom in the southwest are of course not at peace.

Since Xianyu Zhongtong bullied Nanzhao and made the King of Nanzhao unwilling to be humiliated and turned against the Tang Dynasty, Nanzhao has repeatedly provoked the Tang Dynasty on the border. At that time, Li Linfu used this matter to force Yang Guozhong to leave Chang'an City and go to Jiannan to deal with the dispute with Nanzhao.

Yang Guozhong is a slim person. When the Nanzhao Kingdom caused trouble, he was really scared by Li Linfu's design. Now Yang Guozhong has become the prime minister and has greater power. In addition, he still serves as the governor of Jiannan, and at the same time he wants to achieve some military achievements and further consolidate the position of prime minister. At this time, Nanzhao Kingdom dares to cause trouble, so how could Yang Guozhong let it go?

Although Xian Yu Zhongtong resigned as the governor of Jiannan, he still served as deputy envoy.

In August of the tenth year of Tianbao, Yang Guozhong instructed Xian Yu Zhongtong, who was still the deputy envoy of the Jiedushi, led the 80,000 Tang troops in Jiannan to attack Nanzhao, intending to teach Nanzhao a lesson.

The Nanzhao Kingdom was small and weak, and the 80,000 Tang troops could scare the Nanzhao Kingdom to death. The Nanzhao king originally wanted to pick some disputes and exclaimed his anger. He didn't expect to start a war with the Tang Dynasty, but he backfired and almost fell ill.

Fortunately, some ministers offered suggestions, and the Tubo State was fighting fiercely with the Tang Dynasty, so they could ask for reinforcements from the Tubo State.

Xiao Bolu Kingdom was defeated in the battle and the princess was captured. The Emperor of Tubo felt ashamed. In addition, the Tang army in Longyou attacked Tubo, and the Tubo army retreated step by step and passive defense. He was holding his breath. When he heard that Nanzhao Kingdom asked for help, he sent 40,000 Tubo troops to rescue Nanzhao Kingdom without saying a word.

Xianyu Zhongtong is not a powerful general who was fought by Gao Xianzhi and Ge Shuhan, so his ability to command troops was limited, and he didn't know that the Tubo reinforcements arrived.

Eighty thousand Tang troops were attacked by Nanzhao and Tubo coalition forces in the Xier River area, and were defeated miserably, losing 60,000 soldiers. The water of the Xier River was dyed red and filled with corpses.

After all, Xian Yu Zhongtong had a very good relationship with Yang Guozhong. He was kind to Yang Guozhong and attacked Nanzhao under the instruction of Yang Guozhong. In order to avoid this crushing defeat, Yang Guozhong concealed the news of Xian Yu Zhongtong's crushing defeat. What he presented to Emperor Xuanzong of Tang was a small defeat, and the number of losses was reduced several times. However, Emperor Xuanzong of Tang was still furious and revoked Xian Yu Zhongtong's position as deputy governor. Although he lost his official position, Xian Yu Zhongtong's life was saved. He was very grateful to Yang Guozhong.

After defeating the Tang army, Nanzhao Kingdom knew that the Tang Dynasty would not give up, so he simply surrendered to Tubo directly and accepted the title of Tubo emperor, known as the "Eastern Emperor".

I don’t know if it was the Emperor of Tubo who did it on purpose or something. In short, his actions violated Emperor Xuanzong of Tang.

Xiao Nanzhao dared to be the emperor? Emperor Xuanzong of Tang was furious and only felt that the Nanzhao Kingdom betrayed the Tang Dynasty and was extremely humiliated.

The Tang Dynasty was in the Western Regions and Longyou won one after another, and the Tubo was defeated step by step. How could he endure the crushing defeat in the direction of Nanzhao? How could he betray the Tang Dynasty? How could he watch it freely?

In a furious manner, Emperor Xuanzong of Tang issued an order to summon troops from Henan and Hebei to conquer the Nanzhao Kingdom again.

Although the Nanzhao Kingdom was small, its terrain was unique and its jungle was closed. With the Tubo Kingdom as its support, the Tang Dynasty was powerful, but after all, it was defeated by a new defeat and it was not easy to defeat the Nanzhao Kingdom for a while. The battle with the Nanzhao Kingdom would also be a war that lasted for several years.

After all, Yang Guozhong also served as the governor of Jiannan. The battle between Jiannan and Nanzhao Kingdom was defeated. Although the major incident was reduced and Xian Yu Zhongtong was punished, if the situation was not restored, where would he, the governor of Jiannan and the prime minister, be put to the face of him?

Therefore, not only Emperor Xuanzong of Tang attached great importance to the battle against Nanzhao, but Yang Guozhong also attached great importance to it.

Because of planning the Battle of Nanzhao and helping Emperor Xuanzong of Tang handle many government affairs and the affairs of the prime minister himself, Yang Guozhong was so busy that he had no time to cause trouble for Li Fei and Li Bai, which made Li Fei and Li Bai free for a while.

Li Bai was very proud of his spring breeze and was often summoned by Emperor Xuanzong of Tang. He was so happy with the wine and food.

Li Fei was much quieter. Yang Guozhong did not cause trouble for him. He was even more lazy to provoke Yang Guozhong. He went to court every day to go to Jingzhao Yin to investigate the case, fiddled with some gadgets at home, teased his son Li Rui, and discussed with his two wives about "creating people". His life was very comfortable.

The Western Regions, Longyou and Nanzhao Kingdom fought so hard. How could An Lushan, one of the protagonists of the late Xuanzong of Tang Dynasty, not have his own actions? His ambitions are greater than anyone else.
