Qin Sui'an obtained the sign-in system, used a dog charm to save the dying First Emperor, and was awarded the title of "King of Qin", with the same power as the emperor. He brought high-yielding crops to the people and signed Tiger Marquis Xu Chu to serve as the imperial city guard. Ying Zheng was convinced, Zhao Gao and Li Si surrendered, and the Yin and Yang family plotted to seize the secret method. He changed the prophecy of the meteorite based on the sign, so that the First Emperor would die regardless of the ground, and the Qin Dynasty would always belong to Qin Sui'an and Zheng Ge.
