To complete the task, you must first understand the history of the Anxi Protectorate. There is no need to check the information. Based on Wang Anshi's memory, Chen Long found out the information about the Anxi Protectorate.

In the 14th year of Zhenguan in the Tang Dynasty (640th year), Hou Jun gathered to pacify Gaochang and established the Xizhou Protectorate in its place, with its capital in Xizhou. In September of the same year, Anxi Protectorate was established in Jiaohe City to target the Western Turks. The first Protectorate in Anxi Protectorate was Qiao Shiwang, and later Guo Xiaoke took over. At the beginning, there were only a few thousand troops. In the 22nd year of Zhenguan (648), Guo Xiaoke defeated the Kucha Kingdom and moved the Anxi Protectorate to Kucha.

In November of the second year of Xianqing in Emperor Gaozong of Tang Dynasty (657), Su Dingfang decided on the rebellion of Ashinahelu in the Saiye Shui, thus quelling the Western Turks and moved the Anxi Protectorate to the former land of Gaochang. In May of the third year of Xianqing (658), the Anxi Protectorate was moved to Kucha, and the Anxi Protectorate was upgraded to the Great Protectorate.

Later, the territory under the Anxi Protectorate continued to expand and began to form a tug-of-war with Tubo. During this period, a large number of famous generals such as Pei Xingjian and Wang Xiaojie emerged.

During the Zhide period of Emperor Suzong of Tang Dynasty (756-758), in order to quell the Anshi Rebellion, the Tang government recruited troops in Hexi and Longyou. The Anxi soldiers formed the "Anxi Xingying Camp" to suppress the rebellion and helped to recover the two capitals. However, due to the internal transfer of Anxi, Beiting and Hexi, most of the Longyou garrison troops were transferred to the public, and Tubo took the opportunity to occupy Longyou and Hexi one after another. Therefore, the passage between the Anxi Protectorate and the Tang Dynasty was interrupted, but the remaining troops in the four towns of Anxi were still alone to defend.

In the first year of Shangyuan (760), most of the Longyou Army Towns were captured by Tubo. In the first year of Guangde (763), the Tubo regime took advantage of the decline of the Tang Dynasty to seize the Longyou Road. In the winter of that year, Tubo captured Chang'an, the capital of the Tang Dynasty, and evacuated half a month later.

More than ten years later, Tubo took away Liang, Gan and other prefectures in Hexi. The military operations of Tubo caused many difficulties to the Anxi Protectorate, but there were still old generals Li Yuanzhong guarding Beiting, Guo Xin guarding Anxi Protectorate, the two towns and Shatuo, and the Uighurs depended on each other, and Tubo could not capture it for a long time. In the first year of Jianzhong (780), Li Yuanzhong and Guo Xin sent envoys to report the matter indirectly. Dezong commended him and appointed Li Yuanzhong as the Protectorate of Beiting and Guo Xin as the Protectorate of Anxi. Subsequently, Tubo joined forces with Gelulu, and Shatuo attacked the Tang army, Uighurs, and the Tang Dynasty completely lost contact with the Anxi Protectorate.

"When the three Gelu, Baifu Turks were all attached to the Uighurs, and the Uighurs invaded and plundered them. Tubo was given Gelu, and Baifu people attacked Beiting... In the sixth year of Zhenyuan... Uighur Jiegangas fought against Tubo and was in trouble, and Tubo rushed to attack Beiting. The people of Beiting suffered from the Uighurs' pursuit, and they all surrendered to Tubo with Shatuo Chief Zhu Xie and Zhongzhong... Anxi was then extinct, and no one knew how to survive and perish, but Xizhou was still defended by the Tang Dynasty." Chen Longmo recited the records in "Zizhi Tongjian", which is also the last record of the Anxi Protectorate in the official history.

"Gelu!" Chen Long recited this familiar name. In the tenth year of Tianbao, thirty-nine years before the story, Gao Xianzhi, the general of the Right Yulin and the governor of the four towns of Anxi, led a large army and the Dashi Army to meet in Talas. The Tang army with less than 20,000 people and the Dashi Army with as many as 200,000 people fought fiercely for five days without a chance of winning or losing.

However, at this moment, at an important moment when the two sides were stalemate, the Ge Luolu tribes in the Tang army suddenly rebelled and attacked the Tang army with Dashi. Gao Xianzhi was defeated and fled at night. Due to the obstruction of the road, the Pahan tribe blocked the way in front and blocked the road. Fortunately, the Right Wei Guard General Li Siye raised the stick and opened a bloody road for him, and was able to escape.

If it weren't for Gelu's betrayal, the winner of the Battle of Talas might have been the Tang Dynasty. Chen Long had always felt sorry for this when he was reading history books. If he wanted to help Tang restore glory this time, then Tubo and Gelu were all enemies that must be dealt with? Since that's the case, I'll deal with you together this time.

This is, this task should not be easy, right? The Tang Dynasty had entered a period of decline in 790 AD. Emperor Dezong of Tang spent a huge amount of money to welcome the Buddha's bones, the prince of Langya, Sikong, and the secretary of the Secretariat of the Secretariat, and the governor of Lulong, Youzhou and the governor of Ziqing Li Na in Dizhou.

The Tang Dynasty was overwhelmed, and there was still enough energy to help Guo Xin and Yang Xigu who were trapped in Anxi like Emperor Zhang of Han sent a large army to rescue Geng Gong.

So it seems that he can only fight alone in Anxi, relying on the remnants of the Tang army in Kucha and Xizhou to defeat powerful enemies such as Tubo and Geluo.

Guo Xin and Yang Xigu were facing even more severe than Li Yunlong's original situation. Although the enemies Li Yunlong faced were powerful, they were at least in the Central Plains, and they were surrounded by people who were looking forward to their own people. They could rely on these people to continuously obtain manpower and material supplies, and eventually drag the Japanese down.

Guo Xin and Yang Xigu were in the Western Regions where foreign races lived together. In the Central Plains, when the Anxi Protectorate ruled the Western Regions, they might surrender to the Tang Dynasty, but when the Tang Dynasty began to weaken, they would change their past respect and show their fangs. It would be easier to use the power of these people.

However, it is not completely impossible. Although the mixed family of aliens is not good for the Anxi Army, it is difficult for Tubo, Gelu, and Uighurs to completely rule this land. As long as there are appropriate strategies, it is not impossible for these tribes to surrender again to the Anxi Protectorate.

Since he had decided to enter this world, Chen Long seized the opportunity to start collecting information. Chen Long browsed all the historical materials he could find about this period, and also went to the northwest to find the former site of Kucha and Xizhou for a careful tour, and even went to Yang Xigu's temple for sacrifice.

In addition to these, he also looked for information from the Age of Discovery and studied it. Western colonists repeatedly conquered one alien after another with a very small number of people. It would be impossible to have no real skills. Maybe they could find some strategies worth learning from it.

After completing all the preparations, Chen Long chose to enter the transfer world of "The Last Time in the Demon North of the Tang Dynasty". A white light flashed, and Chen Long came from 2019 to 790 AD.

There was darkness in front of him, his mind was a little dizzy, and the strong smell of blood kept drilling into his storm's nose. He struggled to break his eyes, and saw corpses everywhere, including those wearing Tang army armor like him, and thieves dressed in aliens.

"I've got rich! I've got rich! I've got rich!" Suddenly, a scream of excitement came from my ears. A man with a frosty face was gathering bags of copper coins together, making a clattering sound.

Chen Long's mouth showed a smile. The two survivors of the Anxi Army of the Tang Dynasty, the two protagonists of this story, were finally here.
