There were 36 states in the land of Shenzhou in the Tang Dynasty, and one Pujiang and one Luo River run through the entire 36 states. The source of the Luo River water system comes from the Yaochi Tianshui on the edge of Kunlun Tianshan Mountain. Kunlun Tianshui and Yaochi Tianshui are both located in the Four Desolate Kingdoms. The capital of the Four Desolate Kingdoms is Dunhuang City. On the tenth day of the month of birth, Shen Jimiao brought his baby boy Li Taibai to the Four Desolate Kingdoms and settled in the Thousand Buddha Caves on the edge of Xizhao City. Shen Jimiao only does one thing every day, which is to carefully raise and cultivate Li Taibai.

There are two seas in the land of Shenzhou in the Tang Dynasty, the East China Sea and the South China Sea. There are nine fairy mountains above the East China Sea, namely Penglai, Yingzhou, Qiyun, Fanjing, Yunmeng, Yunding, Putuo, Yangming, and Xueyu.

There are sixteen islands above the South China Sea: Crescent Island, Coral, Ryukyu, Fishing Rain, Zhoushan, Penghu, Miyako, Wang'an, Huayang, Jiulong, Nansha, Yongshu, Taiping, Jinlan, Huangyan, and Lindao. Among the sixteen islands, Crescent Island and Coral Island have the largest area, which is so large that it can build a city on it. Lindao is the smallest area, so small that only a small piece of basalt rock extends out of the sea.

The eight islands near the east of the South China Sea are called the East China Island Country. The eight islands in the middle of the South China Sea are called the South China Island Country. The eight islands in the East China Island Country are: Coral, Ryukyu, Fishing Rain, Zhoushan, Penghu, Miyako, Wang'an, and Huayang. The eight islands in the South China Island Country are: Crescent, Kowloon, Nansha, Yongshu, Taiping, Jinlan, Huangyan, and Lin Island.

There is a large island in the South China Sea island country called Crescent Island. There is a city called Shangdu City. The South China Sea island country governs the eight islands in the middle of the South China Sea, and Shangdu City is the capital of the South China Sea island country. The city lord of Shangdu City is Nangong Chenyu.

There is also a large island in the East China Island Country, called Coral Island. There is a city on the Coral Island. The East China Island Country governs the eight islands east of the South China Sea in China. Shangjing is the capital of the East China Island Country. The city lord of Shangjing was originally Dongfang Yuandao, which had been appointed and removed for a short time. Later, Dongfang Yuandao was promoted to the prime minister of the Tang Dynasty because of his deep love from Emperor Tang Li Yu. The position of the city lord in Shangjing was vacant. Under the operation of the new prime minister Dongfang Yuandao, his son Dongfang Yanguang, who was seventeen years old, replaced him as the lord of Shangjing.

It was the eventful autumn of the Tang Dynasty. After the Huang Chaoge Wuyue Uprising, Wang Jianzhi, the lord of the Northern Kingdom City, wanted to take this opportunity to avenge his former blood-sea hatred for his grandfather An Lushan. So he went south with the 500,000 Tingce army, which was originally guarding the border of the Great Wall in the North, touring the south. Later, Wang Jianzhi was caught by Huang Chaoge's plan, and most of the 500,000 Tingce army died in the Junlin Mountains in the northwest of Chang'an City. He himself was cut in half by Huang Chaoge's Yanyue, and died in a different place. After that, the northern territory of the Tang Dynasty was empty.

After the rebellion of Fengyue Huang Chaoge was just quelled in the second year, the tribes of the grassland north of the Great Wall gradually united into a Mengdan Kingdom. Khan Yelu Deguang of the Mengdan Kingdom saw that it was Mu Yue at this time. The war horses on the grassland were dangerous in spring, strong in summer, fat in autumn, and thin in winter. Mu Yue was in summer. It was the time when the war horses on the grassland were strong. There were only tens of thousands of defeated soldiers of the Tingce army who fled back from the Junlin Mountains in the Great Wall in the northern border of the Tang Dynasty.

So in the early months of the second year, Khan Yelu Deguang of the Mengdan Kingdom led 200,000 Iron Feather Cavalry from various tribes of the grassland to the foot of the Great Wall in the North. Iron Feather Cavalry, a pair of arms made of feathers inserted behind the grassland cavalry can increase the speed of the horse's running and increase the combat lethality.

As Yelu Deguang expected, the tens of thousands of Tingce troops who guarded the Great Wall of the North were defeated and defeated in one battle. Then, Yelu Deguang easily crossed the Great Wall of the North and directly occupied the three northwestern states Yongzhou, Tingzhou and Xiongzhou. Zhu Yitian's mother Wang Rong, cousin Liu, cousin Wang Kangping, and Yun Huixian, from Yunyan Village, the northern border, all fled to the mansion of the Young Marshal Zhenguo in Chang'an City.

Since Emperor Tang Li Yu returned to Chang'an from Nanyue Kingdom, all the wealth accumulated by Nanyue Kingdom in decades was brought back to Chang'an City by Li Yu. Therefore, the city lord of Haizhou City, Nanyue Kingdom lost the support of the wealth accumulated by decades and was unable to recruit soldiers to protect Nanyue Kingdom.

In the middle of Mu Yue, Liu Huaiyin and Liu Zhiyuan brothers found out that there were no soldiers in the Haizhou City of Nanyue Kingdom in Yizhou, one of the six prefectures in the East China Sea. So they led the 300,000 Yiwu troops in Yizhou to Haizhou City in Nanyue Kingdom. They took only one day to defend the empty Haizhou City, and controlled the entire territory of Nanyue Kingdom a few days later. Liu Huaiyin and Liu Zhiyuan brothers called themselves the King of Han in Nanyue Kingdom.

On the middle of the month of Mu Yue, the Tang Dynasty was facing internal and external troubles, and all civil and military officials quarreled and chattered in the Hall of Supreme Harmony. The east and the far east proposed that the internal stability must be settled before fighting foreign countries, first ceding land to seek peace, and seek peace from the Mengdan Kingdom in summer and autumn. After all, the iron-feathered cavalry of the Mengdan Kingdom in summer and autumn were fierce in summer and autumn. In the period of summer and autumn, after quelling the rebellion of the Yiwu Army in the south, then gathering all the superior forces of the Tang Dynasty to counterattack the Iron-feathered cavalry of the Mengdan Kingdom in winter. In winter, the war horses in the north were thin and their combat power were greatly damaged, so they could definitely win in one battle. Now the Sixteen Prefectures of Youyun are controlled by Shi Jingfeng, and Shi Jingfeng did not obey the orders of the court. It would be better to ced the Sixteen Prefectures of Youyun to the Khan Yelu Deguang of Mengdan Kingdom, and use Yelu Deguang's 200,000 Iron-feathered cavalry to weaken Shi Jingfeng's military strength.

Emperor Tang Li Yu was so anxious that he and the ant on the hot pan had to stand up to the common people and agreed to the strategy of resolute foreign policy in the east to fight against foreign countries. He ignored the advice of the court officials and ordered people to cut off the territory of the Sixteen State of Youyun on the territory of the thirty-six State of China. He also personally stamped the seal of the imperial seal on the territory of the Sixteen State of Youyun on the territory of the Sixteen State of Youyun on the territory of the Sixty-six State of Youyun on the seal and wrote a letter of peace to Yelu Deguang.

After obtaining the territory of the Sixteen Prefectures of Youyun, which covered the jade seal, Yelu Deguang replied to Emperor Tang Li Yu to agree to seek peace. Then, Yelu Deguang took the territory of the Sixteen Prefectures of Youyun to Youzhou City. Shi Jingfeng, who was already the king of Youyun, did something unexpected to everyone. He opened the city and surrendered, and knelt down at the feet of Yelu Deguan, who was a teenager younger than himself, and called Yelu Deguan the adoptive father. Emperor Tang Li Yu originally wanted to use Yelu Deguan's 200,000 iron feather cavalry to weaken Shi Jingfeng's military strength, but he never expected that people's hearts would be selfish. From the perspective of maximizing his own interests, Shi Jingfeng preserved his military strength, trapped the people of the Sixteen Prefectures of Youyun in the water and fire, and wanted to let the people of the Sixteen Prefectures of Youyun be trampled and ravaged by the 200,000 iron feather cavalry of the northern grassland nation.

Since Yelu Deguang led 200,000 Tieyu cavalry to Youyun Sixteen Prefectures, enjoying the comfortable reception of Shi Jingfeng, his godson in Youzhou. It turned out that the three northwest prefectures he had captured had no time to take care of. Emperor Tang Li Yu took the opportunity to pick up the bargain and immediately ordered Wang Jianzhi's son Wang Kangping and Wang Jianzhi's wife Liu to return to Tingzhou Prefecture and then govern the northern country.

A few days later, Zhu Yitian, the young commander of the country, ordered Zhu Yitian to select some civil and military generals from the court to Tingzhou to rebuild the Tingce Army to protect the Northern Great Wall. The group of high-level officials with outstanding abilities selected by Zhu Yitian were unwilling to go to the Northern Kingdom with him to risk their lives. He had no choice but to select from the lowest-level officials. In the end, there were only more than 30 young officials who had just joined the court, willing to go to the Northern Kingdom with full enthusiasm to rebuild the Tingce Army to guard the Great Wall to fight against the Mengdan Kingdom.

The next day, Zhu Yiwu and Yun Huixian led more than 30 young Tang Dynasty officials and more than 60 personal followers to the northern country. After arriving in Tingzhou, they temporarily lived in Tingzhou Prefecture. At the beginning, their cousin Liu family treated Zhu Yiwu, Yun Huixian and his group with great respect, and were very concerned and supported them in rebuilding the Tingce army to guard the Great Wall.

In the last few days of Mu Yue, Yun Huixian vaguely felt that Liu suddenly changed his attitude towards the reconstruction of the Tingce Army and became indifferent. He also said cold water to some guards in Tingzhou Prefecture from time to time. Yun Huixian estimated that there must be a reason for this, so he said to Zhu Yiwu at night: "Didn't you realize that your cousin's attitude towards the reconstruction of the Tingce Army recently became indifferent? It must be that Meng Dan's country sent an envoy here, which made Liu undecided. I wonder if he would continue to support us."

Zhu Yitian, who was busy with military affairs for a day, was lying on the bed and was about to sleep. When he heard Yun Huixian's statement, he was indifferent to sleep for a moment and thought for a while and said, "It shouldn't be. Tingce Army was the lifelong hard work of his cousin Wang Jianzhi. He was defeated by Huang Chaosong before. Now we are going to rebuild this army. Isn't it not to continue my cousin's will? My cousin's wife should not collude with the envoy of Meng Dan."

Yun Huixian said: "Now that the Iron Feather Cavalry in the Mengdan Kingdom is powerful, I believe my cousin's wife was scared by the previous Iron Feather Army invasion of the Northern Territory. Now she has done such a confused thing. You are a clear-headed person and should be able to foresee what has not happened in advance, not to mention that all kinds of signs are obvious now!"

So the next day, Zhu Yitian called several guards around his cousin Liu and asked them unexpectedly: "I know that the envoys of Mengdan Kingdom have been here for many days. Where are they now?" The guards felt unexpected and could not answer in a hurry. The guards did not discuss the unified response words in advance. They said their own words in a while, and there were many loopholes. Finally, under the majesty of Zhu Yitian pulling out the spirit-cutting sword, he had to stammer and tell the truth.

Zhu Yitian secretly detained the guards to prevent the leak of the news. Then, he immediately summoned his subordinates from more than 100 people brought from Chang'an City and sang. When he was drunk, Zhu Yitian deliberately angered everyone and said, "You and I are both in the northern border countries, and they all want to make achievements by establishing the Tingce Army. But now that the envoys of the Mengdan Kingdom have only been here for a few days, the Liu family is tired of establishing the Tingce Army. If Liu informs the envoys of the Mengdan Kingdom about all the military affairs details of our Tingce Army, wouldn't we all become foods from jackals? What do you think of this?"

Everyone said in unison: "We are in a dangerous situation now. Whether we are alive or dead is up to you, the general."

Zhu Yitian said: "If you don't enter the tiger's den, how can you get a tiger's son? The current method is to pretend to be the guards of Tingzhou Prefecture, kill the envoys of Mengdan Kingdom at night, and destroy all of them. After destroying them, they will publicize them as the guards of Tingzhou Prefecture, so that the Khan Yelu Deguang of Mengdan Kingdom believes that this is what Liu's family does, so that Liu can wholeheartedly support us in establishing the Tingce Army."

Someone said: "This matter should be discussed with Wang Kangping, the lord of Tingzhou City." Zhu Yitian was furious and said: "The success or failure of the establishment of the Tingce Army depends on this matter. Wang Kangping is a man who only obeys his mother's orders. When he hears this, he will definitely inform Liu, so we cannot do this." All the subordinates unanimously said yes.

Just as it was dark every day, Zhu Yitian led a hundred men to the base of Mengdan envoys in Tingzhou City. The wind blew that day, and more than a dozen people hid behind the enemy's base with drums. When they agreed to see the fire, they would beat the war drums and shout loudly, pretending to be like thousands of troops. They ordered others to ambush the door with swords, guns, bows and crossbows. After the arrangement, Zhu Yitian set fire with the wind, and for a while, the hundred men clamored for a long time, and the momentum was noisy. A thousand envoys from Mengdan were in chaos. He heard that they were surrounded by large troops outside the base, and they all fled, but they were not familiar with the terrain and had no way to escape. Zhu Yitian personally killed nearly a hundred Mengdan envoys, and his subordinates also killed nearly a hundred Mengdan envoys, and the remaining hundreds of Mengdan envoys were buried in the sea of ​​fire.

After dawn, Zhu Yitian ordered everyone to wear the clothes of the Tingzhou Prefecture guards and hype them up in the streets and alleys of Tingzhou that Tingzhou Prefecture and Mengdan Kingdom are incompatible. If Mengdan Kingdom sends envoys to come, the outcome will be exactly the same as today. The number of envoys from Mengdan Kingdom will kill as many people as they come.

Afterwards, when the lord of Tingzhou City Wang Kangping and his mother Liu learned about this, they were both shocked. Liu took a sip of tea and suppressed the horror in his heart. After thinking for a while, he immediately sent his son Wang Kangping to find his cousin Zhu Yitian and swore to express his full support for the reconstruction of the Tingce Army in the future.
