In 256 BC, King zhou yun (n·m·4n) listened to King Chukolia and called six countries to send troops to attack the State of Qin in the name of the son of heaven, but failed because the six countries did not cooperate. In 246 BC, Ying Zheng, king of Qin, acceded to the throne.
He appointed Liao Wei, Reese and others to speed up the pace of reunification, bribed the ministers of the six countries with money, disrupted the deployment of the six countries, and sent troops to the East year after year. After years of war, from the Qin Dynasty's destruction of Korea in 230 BC to the demise of Qi in 22 1 BC, the six eastern countries successively unified Qin and established a centralized state.
