People who hold the first view on Guangzong Dune Platform in Xingtai believe that there are many records about the death of Qin Shihuang in Historical Records, which can be found in Biography of Qin Shihuang, Biography of Li Si and Biography of Meng Tian. The cause of death is clear and beyond doubt. In 2 18 BC, Qin Shihuang was assassinated while touring the east, and an auxiliary car behind him was smashed to pieces by the assassin with a heavy hammer. Subsequently, the meteorite engraved with "the first emperor died and divided the land" and the "immortal" with the words "Zulong died this year" were discovered. Qin Shihuang was superstitious, which made him feel uneasy. In order to take refuge from disasters and find the elixir of life, Qin Shihuang listened to the fortune teller's advice and prepared for the fifth cruise. However, due to fatigue all the way, Qin Shihuang fell ill when he arrived in the plain of Tianjin (now near the Shandong Plain). Zhao Gao was ordered to write a suicide note to Fu Su, the eldest son of Qin Shihuang who was ordered to supervise the army Hetao: "I will be buried with Xianyang." Before the letter was sent, Qin Shihuang died in Dune Palace (now near Guangzong, Xingtai City, Hebei Province).
Some scholars believe that Qin Shihuang was ill since childhood, so his constitution was weak. He is willful and has to decide everything by himself; Reading 120 Jin file every day is extremely hard work; The high temperature in July during the cruise, coupled with the above factors, prompted him to fall ill and die on the way. As for what disease he died of, some people think that he died of epilepsy. Seizures are generally divided into four periods: dizziness, stomach upset, sudden loss of consciousness, diaphragm spasm, blue complexion, dilated pupils, apnea, muscle twitching all over the body, foaming at the mouth, and waking up in the last few minutes. Guo Moruo according to "Historical Records? The chronicle of Qin Shihuang records that "the king of Qin is a bee, with long eyes, a stork is a fake, a jackal is a whistle, a tiger is a wolf, and he is ungrateful ..." It is speculated that Qin Shihuang suffered from rickets when he was young and often suffered from bronchitis, so when he grew up, his chest was like a stork and his voice was like a jackal. Later, due to heavy government affairs, meningitis and epilepsy were caused. Later, when Qin Shihuang crossed the Yellow River, he had a seizure, and the back of his head hit the bronze ice guide, which aggravated the condition of meningitis and made people unconscious. When they arrived at the dunes the next day, Zhao Gao and Reese found that Qin Shihuang had been dead for a long time.
Those who hold the second view read several history books about the death of Qin Shihuang carefully and found some suspicious things. The entourage of this trip mainly includes Zhao Gao, Reese, Hu Hai and Meng Yi. Meng Zhen was Meng Tian's younger brother and Fu Su's confidant, but Qin Shihuang was seriously ill on the way and Meng Zhen was sent back to the border. Judging from the sudden personnel changes, this seems to be the plan of Zhao Gao and others. Because Meng Tian led the troops with 300 thousand soldiers stationed in Shang Jun with Fuxi, Meng Yi was sent away from Qin Shihuang, removing Fuxi's eyes and ears; In addition, Zhao Gao was convicted by Meng Qian and sentenced to death. Later, due to the pardon of Qin Shihuang, Zhao Gaocai was restored to his official position. Zhao Gao hated Meng Zhi's guts and vowed to destroy the Montessori family. Zhao Gao sent Meng Zhi away when Qin Shihuang was seriously ill, which also cleared a stumbling block for the implementation of his later strategy.
After the death of Qin Shihuang, Zhao Gao threatened Reese by persuading Hu Hai. After some intrigue, the three men issued letters by impersonating Qin Shihuang, and Hu Hai succeeded to the throne. At the same time, in the name of Qin Shihuang, Fu Su was accused of being unfilial to his son, and Meng Tian was unfaithful to the minister, telling them to commit suicide and not to disobey. After getting the exact news of Fu Su's suicide, Hu Hai, Zhao Gao and Reese ordered the motorcade to travel day and night and quickly return to Xianyang. In order to continue to deceive the subjects, the team did not dare to take shortcuts back to Xianyang, but assumed the posture of continuing to patrol and detoured back to Xianyang. Due to the high temperature in summer, Qin Shihuang's body has rotted and stinked. In order to hide people's eyes and ears, Hu Hai and his party bought many fish and put them in the car to confuse everyone. After arriving in Xianyang, Hu Hai succeeded Qin Ershi and Zhao Gao, and Reese remained the prime minister, but the imperial power actually fell to Zhao Gao. After Zhao Gao succeeded in his plot, he began to kill people around him. He set a trap and cornered Reese. When Reese discovered Zhao Gao's plot, he wrote to report Zhao Gao. Qin Ershi and Hu Hai not only sided with Zhao Gao, but also convicted Lisi, and finally beheaded Lisi in Xianyang. Zhao Gao was promoted to prime minister. Because he can go in and out of the palace, he is called "Prime Minister".
Zhao Gao's ultimate goal is to be emperor, but he can't dominate the living Qin Shihuang. Qin Shihuang was seriously ill on his fifth patrol, which was a godsend for him. After the death of Qin Shihuang, he was able to falsely pass on the testamentary edict and implement his own strategy step by step. Whether Qin Shihuang died of illness or was killed is still inconclusive. If he was killed, how did Zhao Gao kill Qin Shihuang?
