In the seventeenth year of Jian'an (212), Dong Zhao and others wanted to persuade Cao Cao to add the title of Duke of the Kingdom, but were blocked by Xun Yu, so Cao Cao was very dissatisfied with Xun Yu, so he was transferred from the Central Labor ~ Army, after Xun Yu's death, Cao Cao was named the Duke of Wei in the following year.

Three years later, in the twenty-first year of Jian'an (216), Emperor Xian of Han further crowned Cao Cao as the king of Wei, with a status above the princes.

【Dong Zhao persuaded to advance】

After Cao Cao became powerful, Dong Zhao, as an old minister who followed him, said to Cao Cao: "We should explore the ancient system to build and divide the fifth-class titles." ”

Cao Cao said: "It is a saint who builds a fifth-class title, and it is not something that can be formulated by a minister, how can I afford it?" ”

Dong Zhao said: "Since ancient times, no one has ever established such a feats as you do today. Even if there is such merit as you, there is no one who has been in the position of a courtier for a long time. Now Ming Gong you are ashamed that you are still defective in virtue and have not reached the state of perfection, and you are happy to be able to keep your reputation and integrity, and there is no greater responsibility, and the beauty of virtue surpasses that of Yi Yin and Zhou Gong, and has reached the ultimate perfection. However, monarchs like Taijia and King Zhou Cheng may not be able to meet again, and now the people are difficult to educate, even more so than the Yin Dynasty and the Zhou Dynasty, in the position of ministers, let others doubt themselves in major matters, and it is really impossible not to rethink it.

Although you have surpassed the previous generations in prestige and virtue, and you know the law, if you can't lay the foundation at this time and consider it for future generations, you still haven't made it home. The foundation lies in the earth and in the people, and should be gradually established in both areas in order to protect and protect oneself. Ming Gong, your loyal discipline has been revealed, and the majesty of the Son of Heaven has also appeared on his face, when Geng Yi said to Emperor Guangwu under the bed, 'The world is extremely important, and it cannot be obtained by people with his surname', Zhu Ying said to Chun Shenjun, 'In an unpredictable era, serving an undesirable master, how can there be no unexpected people', but they can't be heard. Dong Zhao, I have received your favor very unusually, so I dare not tell the truth. ”

Dong Zhao said this, in essence, he was already persuading Cao Cao~, and Cao Cao later became the prince and called the royal capital has a close relationship with this dialogue.

【Xun Yu's Death】

In the first month of the seventeenth year of Jian'an (212), Cao Cao returned to Yecheng. Emperor Xian of the Han Dynasty ordered Cao Cao to praise the salute when worshipping without having to sing by name on the side, and when entering the court, he could not walk briskly like other ministers, and he could wear boots and swords, just like Xiao He, the prime minister of the Western Han Dynasty. In the same year, Cao Cao carved out Dangyin, Chaoge, and Linshu counties in Hanoi County, Weiguo, Dunqiu, Dongwuyang, and Fagan counties in Dong County, Zhutao, Quzhou, and Nanhe counties in Julu County, Rencheng County in Guangping County, and Xiangguo, Handan, and Yiyang counties in Zhao County to expand Wei County.

At that time, Dong Zhao and others believed that Cao Cao should be promoted to the rank of prince and received the highest courtesy from Jiuxi in recognition of his special merits, and they secretly consulted Xun Yu on this matter. Xun Yu believed that Cao Cao had raised troops to correct the imperial court, stabilize the country, and maintain the practical action of retreating with loyalty; A gentleman loves his neighbor because he loves his virtue, and he should not do so. Cao Cao was dissatisfied with him from then on.

According to the record of "Offering the Emperor Spring and Autumn", Zhao and the princes and generals discussed that it was appropriate to enter the prince of the kingdom with the prime minister, and prepare things in nine tin to show the honor; Shu and Xun Yu said: "In the past, Zhou Dan and Lu Wang, when the Ji family was prosperous, because of the cause of the two saints, the auxiliary wings became the young of the king, and the meritorious service was like that, and he was still knighted, and the tin soil opened the universe." In the last days, Tian Dan drove the strong Qi people, repaid the grievances of the weak Yan, collected the city seventy, and welcomed the king of Xiang; King Xiang rewarded Yu Shan, so that the east has the seal of Yeyi, and the west has the danger of being on the top. In the previous life, he recorded his merits, and he was so thick. Today, Cao Gong was overturned by the sea, the temple was burned, the armor was bowed, the expedition was circulating, the wind and rain were bathed, and for 30 years, the group of fierce people were killed, and the Han family was restored, and the Liu family was enshrined. If the mountains and hills are the same, how can they be judged on the same day? Today's disciples and generals are heroes, and Hou a county, how can the world hope for this! ”

In the same year, Cao Cao was just preparing to conquer Sun Quan, so he asked Xun Yu to be sent to Qian County to comfort the army. Cao Cao's army arrived in Weixu, Xun Yu stayed in Yangzhou Shouchun due to illness, and died of depression at the age of fifty. Later, he was posthumously honored as a marquis. The following year, Cao Cao was promoted to Duke of Wei.

According to the "Spring and Autumn Period of Wei", Cao Cao gave food to Xun Yu, Xun Yu opened the food vessel and saw that there was nothing in it, so he was forced to take poison and commit suicide. In the second year of Xianxi (265), Xun Yu was posthumously awarded the title of Tai Lieutenant.

In the eighteenth year of Jian'an (213), shortly after Xun Yu's death, Emperor Xian of the Han Dynasty issued an edict to merge the fourteen states and restore the establishment of Kyushu.

On the tenth day of the fifth month, Emperor Xian of the Han Dynasty sent the imperial historian Xi Xi to Yecheng with the emperor's talismans, and officially enshrined Cao Cao as the Duke of Wei (Note 1), and the territory included Hedong, Hexi, Wei County, Zhao State, Zhongshan, Changshan, Julu, Anping, Ganling, Pingyuan, etc., a total of ten counties and counties, and gave Jiuxi to build the Wei State and set the capital of the country in Yecheng. Later, Cao Cao placed hundreds of officials such as prime ministers, captains, and generals.

In the same year, Emperor Xian of the Han Dynasty married the three daughters of Cao Gong and named them nobles, the youngest of whom temporarily stayed in Wei and entered the palace when he grew up. The following year, Empress Fu was deposed. In the twentieth year of Jian'an (215), Emperor Xian of the Han Dynasty established Cao Cao's second daughter Cao Jie as the queen.

In March of the 19th year of Jian'an (214), Emperor Xian of the Han Dynasty elevated the status of the Duke of Wei above the princes and kings, and awarded him a golden seal, a red ribbon, and a traveling crown (all three of which were the system of the kings of the Eastern Han Dynasty).

In February of the twenty-first year of Jian'an (216), Cao Cao pacified Hanzhong and returned to Yecheng. On the third day of the third month of March, he personally went to his home field to farm. In May, Emperor Xian of the Han Dynasty crowned Duke Cao as the King of Wei. Daijun Karasuma represented Shan Yu Pufulu and his subordinate Hou Wang to meet Emperor Xian of Han. Emperor Xian named the daughter of the King of Wei as a princess, and gave her Tang Mu as a food land. In July, the Xiongnu Nandan Yu Huchuquan led his famous king to congratulate them, and the king of Wei entertained them with courtesy, and kept them in the state of Wei, and let the king of Youxian go to supervise their country. In August, the king of Wei appointed Zhong Xuan of Dali as the minister of state of Wei.

At this time, Cao Cao was already on the throne of the princes and kings, and he was not called a minister, and he was not worshiped by the edict, and he worshipped the world with the crown of the Son of Heaven, the car uniform, the flag, and the suburbs of Lile.

He was only nominally a Hanchen, but in fact he was already the emperor.
