After Qin Shihuang, the first emperor through the ages, made great efforts to govern for ten years and became the king of Qin, Lv Buwei became more powerful. Moreover, he also won the title of "Guan Zhong". His family is very big, with tens of thousands of children and rich. At the same time, in order to expand his influence, he gathered many people to collect historical materials, and finally compiled Lv Chunqiu. Before being sent to Zi Chu by Lv Buwei, Empress Zhao had a close relationship with her. Now, despite her prominent position, Zi Chu has passed away. After being widowed for a long time, she and Lv Buwei came together again. At this point, Qin Shihuang has grown up, and Lv Buwei is also afraid that his affair with the Queen Mother will be discovered, which will lead to fatal disaster. So he found a body double for Empress Zhao, that is, Laoyi, and asked him to pretend to be a eunuch. When he was clean, Empress Dowager Zhao bribed the executioner and let false eunuch in for Empress Dowager Zhao's pleasure. In this way, beside Qin Shihuang, there are two people who pose a threat to his regime, one is Lv Buwei and the other is Ai. In the eighth year of King Qin, that is, in 239 BC, Qin Shihuang was twenty-one years old. According to the old system of Qin, the coronation ceremony was held in the second year, and then he could lead the government. At this time, however, He Ai demonstrated to him: Lv Buwei publicly concocted The Spring and Autumn Annals of Lu, while Lao Ai relied on his influence to divide the land and seal the marquis. Qin Shihuang remained silent in the face of provocation, but he still held the coronation ceremony as planned, but Lao Ai couldn't wait. He wanted to take the opportunity to rebel and kill Qin Shihuang. As a result, Qin Shihuang, who had long been on guard, calmed him down, caught himself, and finally tortured him and killed the three families. His accomplices killed more than 20 people, involving as many as 4000 people. Two illegitimate children of Empress Zhao and Lao Ai were also killed, while Empress Zhao was placed under house arrest. After being persuaded by ministers, Qin Shihuang personally returned to Xianyang with his mother. In the second year of getting rid of Lao Ai, Qin Shihuang got rid of Lv Buwei's prime minister, drove him out of Xianyang and returned to his fief Luoyang. Two years later, in order to avoid collusion between Lv Buwei and other countries, Qin Shihuang sent someone to send Lv Buwei a suicide note. In his letter, he rebuked Lv Buwei: "What contribution have you made to the State of Qin, but you can seize Luoyang and eat 100,000 yuan? What is your relationship with Qin, but you got the title of Guanzhong? Go to Xishu for me! " Lv Buwei knew that he would die in the end, so he simply took poison and committed suicide. When the threat to his own regime was eliminated, Qin Shihuang began to take military action against the six eastern countries. He inherited the heritage of his ancestors and carried it forward. During the reign of Qin Shihuang, there were a number of talented civil servants and military commanders, such as Reese and Liao Wei, who were good at espionage, and Yao Jia and Dunwei. Military commanders include Meng Tian, Wu Meng, Wang Jian and Wang Ben. Qin Shihuang continued to use the strategic policy of "making friends far away and attacking near", and spent ten years before and after destroying the six countries and unifying China. Korea was the first to be wiped out. In the 14th year of the Qin Dynasty, that is, in 233 BC, South Korea ceded territory to become a vassal, which failed to save the fate of extinction. Three years later, Qin captured the king of South Korea and destroyed South Korea. Then Qin attacked Zhao and captured Zhao Wang. Gong Zijia fled to Dai Jun (now Yuxian County, Hebei Province) and was called Dai Wang. In the twenty-fifth year of the King of Qin, Dai Wang was also captured, and Zhao finally perished. In the twentieth year of the King of Qin, Wang Jianling led the troops to attack Yan. To the west of Yishui, Qin defeated Yan and Dai. Capture Ji Cheng (now Beijing), the capital of Yan State. The prince fled to Liaodong. Later, the prince had to kill Taizi Dan, who sent Jing Ke to assassinate the king of Qin, and dedicated his head to Qin Jun for peace. By the twenty-fifth year of the King of Qin, the last king of the State of Yan, Xi, was captured and the State of Yan perished. At the same time, Wei was destroyed by Qin Jun. In the twenty-third year of the King of Qin, Qin Jun, who attacked Chu, was defeated by the Chu army because he had too few troops. The King of Qin sent veteran Wang Jian to war, followed his advice and gave 600,000 troops. As a result, it took Wang Jian three years to finally win the state of Chu. Qi was finally wiped out. When Qin fought against the other five countries in succession, Qi not only stood by and made an alliance with Qin, but didn't realize that his future was the same as that of the other five countries. Therefore, Qi did not make any preparations for war. When the Five Kingdoms were destroyed in the twenty-sixth year of the King of Qin, Qi sent troops to prepare for resisting Qin and broke off diplomatic relations with Qin, but it was too late. After Wang Ben, the general of the State of Qin, finally destroyed the State of Yan, he led a large-scale army south and captured the King of Qi alive in World War I ... At this point, the State of Qin destroyed six countries in ten years and unified China. After Qin Shihuang pacified the world by force, he carried out a series of reform measures, which played a great role in the unification and development of China's politics, economy and culture. First of all, Qin Shihuang changed the traditional title of emperor. He asked ministers to discuss his title. Some advocate the use of "emperor", while others advocate the use of "emperor", mainly from the ancient legends of Huang Sanhe and Five Emperors. Therefore, Qin Shihuang thought that his contribution was higher than that of Huang Sanhe and Wudi, and finally called the emperor and the emperor "emperors". The emperor mastered the state power of the whole country, instead of enfeoffing governors and managing a place like the Western Zhou Dynasty. As a result, the governors acted in their own way, and the central government could not manage it, which led to chaos in the world. In order to maintain the dignity of the emperor, the name was also stipulated: the emperor claimed to use "I", the emperor's life was called "system" and the order was called "imperial decree". The emperor's seal is made of jade, called the jade seal. Only the emperor's seal can be called a seal. At the same time, the emperor's wife is called "the queen", his father is called "the emperor's father" and his mother is called "the empress dowager".
