The emperor immigrated to Shandong.

Qin Shihuang was addicted to immortality.

After the unremitting efforts of six generations of kings since Qin Xiaogong, the national strength of Qin finally surpassed that of other countries in the Warring States period. Ten years later, Qin Shihuang completed the unification of China, which was not easy, because it was an unprecedented feat. How to manage Qin became a problem, so Qin Shihuang adopted emperor system, county system, unified measurement, writing and coins, and built the Great Wall in the north to resist the Huns. Immigrating to the land of Chinese culture in the south led to Qin Shihuang's overwork and physical problems, so Qin Shihuang began to look for ways to live forever.

Xu Fu is a famous alchemist trusted by Qin Shihuang.

Qin Shihuang was bent on immortality in his later years, so he invited many Jianghu alchemists to help Qin Shihuang refine the alchemy, and Xu Fu was the most important thing for Qin Shihuang. Trev has his own unique theory. He thinks there is a Penglai fairy island in the sea east of Qin. There are many immortals living on Xiandao. As long as you find Penglai Fairy Island, you can get the elixir for Qin Shihuang, but you need to take 500 boys and girls as followers to Penglai Fairy Island. So Qin Shihuang believed Wei Xiao's words and helped Wei Xiao prepare ships and virgins to go to sea, but Wei Xiao was gone forever, which led to Qin Shihuang's great anger and killed many alchemists.

Chui fook went to Japan today.

After investigation, the place Xu Fudong crossed should be today's Japan Island, because the historical origin of Japan is probably in the Qin Dynasty in China. After arriving in Japan, Xu Fu found that there were some primitive tribes there, so relying on the grain seeds and various advanced farming tools brought by Qin, Japan's civilization developed rapidly and gradually formed a country. Xu Fu is likely to be regarded as the emperor by the Japanese people, but this is only speculation, and the real situation is unknown now.
