(Recommend the legend of brocade, the book of my friend Hu family's eldest young master, although the number of words is not much, but the writing is more fine, if you are interested, you can take a look!) )

As early as the beginning of his reign, he had the idea of making peace with the Central Plains Empire.

However, at that time, the forces of Tubo were still fighting in the valley of the Brahmaputra River south of the Tanggula Mountains, fighting with small tribes such as Subi all day long.

Although the current Nangri Zanzanzan, he is still only a remote and small country Zampu, but he thinks very highly of himself, and the envoys sent by Tubo made it clear to the Sui Empire's monarchs and ministers at the beginning that he Zampu is not going to marry a civilian woman who is named a princess, but a real princess of the royal family.

When Yang Guang heard that the Tibetan envoy proposed to marry his own daughter to them, he was really angry.

He only has two daughters in his life, the eldest daughter Princess Nanyang has already married Yu Wenhua's younger brother Yu Wenshi in the nineteenth year of the emperor, and the second daughter is still relatively young, and in the original history, she will be married by Yang Guangxu to his cousin Li Yuan's second son Li Shimin.

is Li Shimin's Concubine Yang, and Li Ke is her and Li Shimin's child.

At this time, Yang Guang heard that a barbaric chieftain who was nearly forty years old actually asked him to marry his ten-year-old daughter to him, which made Yang Guang very angry, he could not be a good emperor, but to his wife

, my daughter is still very maintained.

Soon the arrogant and impudent Tibetan envoys were expelled from Chang'an City by the angry Yang Guang, although some ministers suggested that even if they did not agree to the requests of the Tibetans, they should entertain the Tibetan envoys, but Yang Guang did not take these people's advice.

This news was quickly spread to the Xia State by the spies arranged by Wang Ze beside Yang Guang, and Wang Ze sighed that it was not unreasonable for Tubo to be strong in the next hundred years, and with such a long-term vision, a country and power would be greatly developed.

Knowing that Emperor Sui was furious and the envoy was rudely expelled, Nang Ri Praise was not discouraged by the rejection, after all, he also knew how the daughter of the Emperor of Heaven in the Central Plains of the Sui Empire could easily marry him? What's more, I only knew that the emperor's eldest daughter had been married, and the girl who was not married was only ten years old.

Next, on the one hand, he sent other envoys to Yang Guang again to ask Yang Guang to marry other clan girls, and on the other hand, he took advantage of the gap between the Xia army and the Sui army to mobilize a large army to threaten Lintao and Jincheng counties from the area of Caohan County, one of the four counties of Tuyuhun.

The two counties of Lintao and Jincheng are the key gateways to defend the land of Guanzhong, and once the county of Longxi is lost, it will all be presented in front of the Tubo army, so that the Tubo army can even march east along the Weishui, sweeping the entire Guanzhong land, and even threatening Chang'an City.

Even if Yang Guang is currently stationed in Luoyang, the eastern capital, Chang'an City is the capital of the Great Sui Empire after all, and once it falls, the consequences are unimaginable, which makes the entire Sui Empire nervous again, after all, most of the newly established recruits of the Sui army are far less effective than the veterans of the Tubo army.

Seeing that the Tubo people suddenly overwhelmed the border, there was a momentum that the Sui Empire would join forces with the Xia State to attack the Sui Empire if he did not agree to make peace, so that Yang Yichen, the general manager of the Longyou marching army stationed in Jincheng and Lintao, had to urgently transfer troops to defend, and at the same time constantly sent urgent reports to Yang Guang.

Faced with such a situation, Yang Guang had to hesitate, facing the simultaneous threat of Xia and Tubo, it seemed that it was the right solution to agree to Tubo's request to unite with Tubo to deal with Xia State.

Soon, the Sui Empire clan finally found a good-looking concubine daughter, so that a large number of craftsmen and wealth as dowries could solve this big problem.

However, things are often full of variables, and just after the threat of Tubo was solved, there was a big problem in the direction of Hebei.

In the past two months, Yu Zhongwen has led hundreds of thousands of troops to constantly serve as sparring partners for the Xia army on the opposite side, and it seems that the fight is also very powerful, and by the way, the people of the Sui Empire, who do not know the truth, have gradually restored a little confidence in their country.

However, both Yu Zhongwen and Yang Guang knew what was going on, but they could only continue to expand the army while exercising the combat effectiveness of the army.

If this continued, the Sui Empire could barely hold on, but at this time, Yang Xuangan, who was originally in charge of the logistics of nearly one million Sui troops, suddenly rebelled in Wei County (Yecheng).

Since Yang Su's death, the Yang family has been constantly suppressed by Yang Guang, Yang Xuangan, as Yang Su's eldest son, of course, has suffered a lot, so he has long been dissatisfied, after Wei County raised troops, he occupied a large number of Sui Empire ordnance and baggage stored in the city, and then quickly surrendered the Sui army around Wei County and Dong County based on 20,000 people in the headquarters.

Based on Yang Xuangan's bravery, Yang Su's remnants, and even the encouragement of other forces in the Longxianbei military group, the Sui troops near Wei County actually joined one after another, and in just ten days, he actually had more than 100,000 troops.

In the process of Yang Xuangan's rebellion, there is a person whose role cannot be ignored, that is, Li Mi, the Duke of Pushan in the Sui Empire, to a large extent, Li Mi played the role of Yang Xuangan's military advisor, and Yang Xuangan was able to finally make up his mind to rebel was also encouraged by him.

After Yang Xuangan raised troops and occupied the very important Wei County, Li Mi's first suggestion to him was to immediately go north to attack the back of Yu Zhongwen's army, while recruiting hundreds of thousands of Sui troops to expand their strength, and on the other hand, to proclaim vassal to Xia and obtain the support of Xia.

Li Mi suggested to Yang Xuangan that after recruiting the hundreds of thousands of Sui troops, he could support the army and occupy the north of the river, while seeking development and at the same time contacting the forces dissatisfied with Yang Guang in Guanzhong, and then attack the eastern capital Luoyang with hundreds of thousands of people, so that the emperor's hegemony could be achieved.

However, Yang Xuan felt that everything else was easy to say, but he was unwilling to listen to this one, because he had been aggrieved by Yang Guang too much over the years, so he only adopted the second strategy given to him by Li Mi, that is, to wave his army to Luoyang and capture Yang Guang.

For Yang Xuangan, as long as Yang Guang is taken down, he can coerce the Son of Heaven to order the princes, and there are a large number of ordnance and weapons in the eastern capital Luoyang, and the grain stored in more than a dozen large granaries such as Changping and Luokou warehouses here is enough to feed hundreds of thousands of troops for more than ten years.

On the one hand, Yang Xuangan continued to garrison Wei County with his younger brother Yang Jishan led more than 20,000 troops and cut off the back road of Yu Zhongwen's army, while he himself led 120,000 troops along the Yellow River to Luoyang, the eastern capital.

The news that a large number of officials had defected to Yang Xuangan made Yang Guang very angry, but it made him even more worried, because at this time, the entire Eastern Capital was only defended by an army of 80,000 troops, and it was full of Yang Su's old protégés before his death, and once Yang Xuangan attacked, it was difficult to guarantee that these armies would not rebel.

At this moment, except for a few generals such as Yu Wenhua and a few other generals around Yang Guang, he couldn't spare any manpower to oppose Yang Xuangan.

What made Yang Guang feel even more aggrieved was that although he suppressed the Yang Su family to a large extent because he was afraid of Yang Su's influence after Yang Su's death, Yang Guang consciously made sufficient compensation in terms of money and materials.

Even if it was normal for others to rebel first, but he never expected that it would be Yang Xuangan who would rebel at this juncture, Yang Guang ordered Wei Meng to defend Xingyang to defend this gateway city of Luoyang, and at the same time recruit soldiers around the river in Luoyang City with a lot of money.

Although another 100,000 soldiers were recruited in just a few days, these troops composed of hawkers, coolies, dock workers, and homeless people could not immediately form a fighting force, and Yang Guang needed more time to train these people into a working army.

Seeing that Yang Xuangan's army was getting closer and closer, fortunately, at the critical moment, Zhang Xutuo, who was originally the Taishou of Liang County, actually led more than 10,000 county soldiers to rush to the aid of Xingyang County, which was very important, and united with Wei Meng's more than 10,000 defenders here to desperately block the 120,000 army led by Yang Xuangan.

After all, Yang Xuangan's army has more than 100,000 people, and the soldiers brought by Zhang Xutuo and the original army in the city add up to only more than 20,000 people, so after desperately holding on to it for three days, the city has gradually become undefensible.

Fortunately, at this time, Yang Guang's two sons Yang Yu and Yue Wang Yang Tong urgently led their troops back to help, and at the moment when Yang Xuangan was about to break through the city, they launched an offensive from behind.

Yang Xuangan never expected that the two of them would be able to come to the rescue so quickly, Yang Xuangan's army had been fighting fiercely for several days before, and then he was hit hard in the back and had to flee in defeat.

Yang Guang was particularly angry about Yang Xuangan's betrayal, and sent a large army to chase and kill, especially Wang Shichong, the general of the forbidden army, who was the most brave, and finally defeated Yang Jishan who came to rescue Yang Xuangan in Liyang County, and forced Yang Xuangan to death in a reed swing by the Yellow River, and Yang Jishan was captured.

With the death of Yang Xuangan, the threat of the eastern capital Luoyang was finally fully lifted, but this sudden rebellion was a fatal blow to the Sui Empire.

Originally, the Xia army of Shanggu County still had the heart to accompany Yu Zhongwen's troops to fight in rotation and constantly train their army's combat effectiveness, but when Yu Zhongwen's troops rebelled because of Yang Xuangan's rebellion, Xia Jun no longer had the heart to accompany Sui Jun to exercise.

Although the Xia army did not move south, it still captured more than 300,000 prisoners of war, only tens of thousands of people were killed, and the other more than 100,000 people were scattered, and even the general Zhongwen was nowhere to be found in the chaos.

Because of the rout of Yu Zhongwen's department, the Sui Empire's military strength in Hebei was completely dispersed, even if the Xia army did not take advantage of the situation to move south, Yang Guang must quickly replenish the military strength here.

But at this time, because of the previous series of forced conscriptions, the people of the Sui Empire were full of disgust for joining the army, and in the face of endless conscriptions, someone finally took the lead and held the anti-flag.

This person is no one else, or Zhishilang Wang Bo.
