Fall
Liu Bang entered the pass and King of Qin Ziying came out.

The Qin people were originally vassals of Zhou in the west, and Qin Xianggong was classified as a vassal because he escorted King Ping of Zhou to move eastward. During the Warring States period, Qin Duke Xiao appointed Shang Yang to carry out reforms, and the national power ranked first among the seven powers. King of QinYing Zheng inherited the "remnants of the Sixth Generation". Starting from 230 BC, he successively attacked the six kingdoms of Han, Zhao, Wei, Chu, Yan, and Qi in ten years, and established the first unified centralized dynasty in Chinese history in 221 BC.

Ying Zheng claimed to be the "First Emperor" and formed the central government with three ministers and nine ministers. He comprehensively implemented the commandery-and-county system in the local areas and unified writing, weights and measures, currency and railway tracks. Attacking the Xiongnu from the north, building the Great Wall, pacifying Baiyue in the south, and digging the Ling Canal established the basic pattern of China's territory and political system for the next two thousand years. However, he burned books and harassed Confucian scholars, imposed harsh punishments, and built major projects such as Epang Palace and Lishan Mausoleum. The taxes and servitude were heavy and the people were in great hardship.

In 210 BC, Qin Shihuang died of illness in a sand dune during a tour. Zhao Gao and Li Si tampered with the imperial edict, forced the eldest son Fu Su to death, and established the youngest son Hu Hai as the Second Emperor. The following year, Chen Sheng and Wu Guang rose up in Daze Township, and the old nobles of the six countries returned to their countries one after another. In 207 BC, Xiang Yu defeated the main force of the Qin army in Julu. In the same year, Liu Bang led his army into the pass. King of Qin Ziying surrendered and Qin dynasty was destroyed. It was only fourteen years before the unification of the six kingdoms.

After crossing the river, "all the boats sank and the cauldrons and steamers were broken" to show that they were destined to die. He defeated the Qin army in nine battles and captured Wang Li. Soon Zhang Han led more than 200,000 Qin troops to surrender, and the main force of the Qin army was destroyed.
