In April of the twentieth year of the emperor's reign (600), Bujia Khan (Datou Khan, who fled in the nineteenth year of the emperor's reign) led his troops to invade the Sui border after rectifying the Turks. The border pass was urgent, Emperor Wen of Sui ordered Yang Guang, the king of Jin, and Yang Su, the right servant of Shangshu, to send troops to Lingzhou (Zhihuile, now southwest of Lingwu, Ningxia), and Yang Liang, the king of Han, and Shi Wansui sent troops to Shuozhou (Zhishanyang, now Shuo County, Shanxi) to attack Bujia Khan. Shi Wansui led Zhang Dinghe, the generals Li Duan, and Yang Yichen out of the fortress, and the army went to Dajin Mountain (now Daqingshan, Inner Mongolia), and Bujia determined that the commander of the Sui army was Shi Wansui who was the mighty Dunhuang in that year, and hurriedly led the army to retreat. Shi Wansui waved his horse to pursue more than 100 miles, broke the Turkic army, and killed thousands.

In October of the same year, because of the extravagance of the crown prince Yang Yong, and the false accusation of traitors, Emperor Wen of Sui disregarded the opposition of the ministers, and made up his mind to choose a new prince, he derogated the people of the East Palace, drove the palace of the king, and promoted the people around him, under the instruction of Emperor Wen, from Xuanwu Gate to Zhide Gate, Yang Yong's big and small affairs were all supervised, as for the guards of the East Palace, Yongmeng was all transferred, and the official Ji Wei around him was bought by Yang Guang, Emperor Wen also asked the warlock to look at all his sons to see which one can inherit the throne in the future, all of this makes people realize that the wind direction of the empire has changed。

In November of the same year, Shi Wansui returned triumphantly, and his right servant Yang Su was jealous of his merits, and said to Shi Wansui in front of Emperor Wen of Sui, saying: "The Turks have surrendered, and besides, they are not originally in the Kou, but just grazing." Therefore, the credit for his work was concealed, and no credit was given. Shi Wansui stated several times that Emperor Wen of Sui had not yet woken up.

At this time, Emperor Wen of Sui returned to Beijing from the beginning of Renshou Palace, and had just abolished the crown prince Yang Yong, so he strictly prevented the East Palace from forming a party and plotting a mutiny. Emperor Wen of Sui asked Shi Wansui where he was, and Shi Wansui was in the court at that time, but Yang Su saw that Emperor Wen of Sui was angry, so he deliberately said: "Long live to visit the East Palace." "To provoke Emperor Wen of Sui. Emperor Wen of Sui really believed it and immediately ordered to summon Shi Wansui. At that time, hundreds of soldiers went out to claim grievances in the court, and Shi Wansui said to everyone: "I will state your merits to the emperor with all my might, and the matter will be resolved." After Shi Wansui saw Emperor Wen of Sui, he said: "The soldiers are meritorious, but they are suppressed by the imperial court!" His tone was fierce and indignant, and he was not obedient to Emperor Wen of Sui.

Emperor Wen of Sui became more and more furious, and on the ninth day of the tenth month of the lunar calendar (that is, November 20, 600 AD), he ordered the warriors to violently kill Shi Wansui in the court. After Shi Wansui's death, Emperor Wen of Sui regretted it, but for the sake of dignity, he still issued an edict listing many crimes, raided the general's mansion, and exiled the Shi family to his family, but no one noticed that Shi Wansui's daughter Shi Hanshuang had disappeared for a long time.

After the news came out, Gao Xi sat in the study and pondered for a long time, as if he had made some important decision, and then, one after another, instructions were sent to all directions through the flying pigeon, and Gao Fu, who had been silent for a long time, also moved like a new life.

It was night, in the middle of Gaofu's study, Gao Xi looked at the six people kneeling in front of him, and said slowly: " Qingli, you and Xuanji and Rakshasa will leave Jingshi early tomorrow morning, go west to Zhangye County, after settling down, the flying pigeon will pass the book to Di Ting, as for Di Ting, after receiving the information, quickly inform the old man, at the right time, you and Yu Gu and Jizo with Wen Cheng and I prepared for you also quickly left Jingshi, go to Zhangye County and Qingli to reconcile, I will write the follow-up things in a letter, and then open it after arriving in Zhangye County, and I left a letter for Wen Cheng, and when Wen Cheng has the ability to achieve a career, you will hand it over to him。 ”

One of the six people said to a big man with a tiger's back and a bear's waist: "My lord, if something goes wrong, with the martial arts and power of the six people under him, he can also ensure the safe exit of the mansion from Chang'an, why did you arrange it like this?" Gao Xi said angrily: "Everything is carried out according to the old man's orders, I have made up my mind, and it is also a precaution." "Obey the order, and the subordinates retire. Then the six disappeared into the study.

In the fourth year of Renshou (604), Emperor Wen of Sui died. After Yang Guang ascended the throne, he was known as Emperor Yang of Sui in history, and he was too often to worship Gao Gong. Yang Guang issued an edict to collect the music workers of the Northern Zhou Dynasty and the Northern Qi Dynasty and the scattered music of the world, and Gao Gong played to stop it, and Emperor Yang of Sui was greatly displeased, and rejected Gao Xi's excerpts several times.

In the autumn of the same year, a firm named 'Wencheng' opened in Beijing, and on the opening day, Taichang Gao Xi personally wrote the inscription "Fortune and Prosperity" to congratulate, and there were rumors that the owner behind the Yun Wencheng firm was the Changsha Song family, and there was also a precursor to the Changsha Song family's business expansion from the south to the north.

On the second day of opening, the owner of Wencheng firm announced that he had reached a cooperation with a merchant surnamed Chu in the Western Regions, and the merchant of the Western Regions invested 300,000 taels of silver in Wencheng firm.

At the same time, Wencheng firm specializes in selling a kind of fine wine from Zhangye County, according to the Gao Tai Chang Gao who has drunk this wine, with Mr. Wuliu's "Drinking" poem No. 7 in the "Pan this forget the worries, far away from my world; although a tendon is still in, although a look is still in, the cup is full of self-pouring" to describe the most appropriate, in a moment, Zhangye County drunk in Chang'an doubled in value, and gradually became a symbol of elevated status among the wealthy.

In the third year of the Great Cause (607 AD), Emperor Yang of Sui ordered the northern tour of the Turks, in order to cooperate with the northern tour of Emperor Yang of Sui, Yu Wenkai, a skilled craftsman at that time, also built a palace that could walk for Emperor Yang of Sui, which could accommodate hundreds of guards, and was equipped with "Xingcheng" guards on both sides of the palace, the so-called "Xingcheng", which was recorded to be as long as 2,000 steps, and could be driven forward by the wheel axle. In June, Emperor Yang of the Sui Dynasty and his entourage were stationed in Yulin County (southwest of present-day Tuoketuo, Inner Mongolia).

Emperor Yang wanted to go out of the Great Wall to Saibei to show off his military might, and he wanted to go directly through the Turks to reach Zhuo County, fearing that the Qimin Khan would be disturbed and frightened, so he first sent Sun Sheng, the general of Wuwei, to announce the emperor's holy decree. Qimin Khan was ordered by the edict, so he summoned dozens of chiefs of the various states to gather together to wait for the Great Sui Emperor.

After receiving the Qimin Khan's table, Emperor Yang of Sui summoned the Qimin Khan and rewarded him with 200,000 silk horses, and rewarded his subordinates with their own differences. He also gave the Qimin Khan chariots (the chariots used by the ancient princes), horses, drum music, flags, and the privilege of worshipping the Son of Heaven without his name, and his status was above that of the princes and kings.

Emperor Yang's favor and courtesy to the Qimin Khan were too excessive, causing many ministers in the court to oppose it, Gao Gong said to He Chou, the secretary of the Taifu: "This Hu man knows the truth of the Central Plains, the mountains and rivers are dangerous and easy, I am afraid that he will become a disaster for future generations." Then he said: "The old man has fought with the Hu people several times in his life, and the Hu people and wolves will blindly give grace, but it will backfire." ”

At the beginning of summer (early June) of the same year, Emperor Yang of the Sui Dynasty sent more than 100,000 men to build the Great Wall, west from Yulin, east to the Purple River, although this section of the Great Wall from Inner Mongolia to Shanxi is not long, but Emperor Yang of the Sui Dynasty ordered the completion of the repair within the month, due to the tight construction period, resulting in countless people who died on the spot, and the people complained about it all over the field for a time. Gao Cheng was very worried when he learned about it, and said to Taichang Cheng Li Yi: "The Zhou Dynasty perished because of good pleasure, Yin Jian is not far away, how can it be like this?" Taichang Cheng Li Yi said: "Your Majesty is at this time to make great progress, if I wait for the performance to stop the fear of criticism, and Your Majesty is dissatisfied." ”

In July of the third year of the Great Cause, Emperor Yang of Sui was slandered by villains, and in order to eradicate the remnants of the party of the abolished prince Yang Yong, he issued an edict to kill Gao Xi, He Ruobi, Yu Wenbi and others for the crime of "slandering the imperial court", and the families of the criminalized officials were all relocated and exiled, and their property was confiscated.

At this point, Emperor Yang Guang of the Sui Dynasty began to build a large number of buildings, extravagance became a trend, and years of conquest led to the boiling of public resentment, and the Sui Dynasty gradually began to come to an end......
