In 221 BC, Ying Zheng defeated the six kingdoms and unified the world. The remnants of the six kingdoms were still running around in secret. Those magical magicians deceived the First Emperor to find the elixir of immortality all day long. The national power of Qin was greatly tortured. In the early winter of 220 BC, the barbarians from Baiyue in the south invaded the territory again. The First Emperor wanted to personally lead his troops to deal with them, but the horse under his crotch was not strong enough and he could only wait for a while. In the Qilin Hall, Ying Zheng announced that he was going to Wujiabao to pick up some war horses today. The affairs of the court were to be handled by Young Master Fusu first, with Zhao Gao assisting him.
