In 221 BC, Qin Shihuang unified the six kingdoms and believed that his achievements were greater than those of the Three Sovereigns and Five Emperors. He didn't know that this was only one eleventh of the world's territory.
Chen Zihao, a doctor of materials science, accidentally traveled through time and opened his eyes to Bolangsha, the historical site where Zhang Liang assassinated Qin Shihuang. He rescued Ying Zheng, presented a solar tablet, and opened a complete map of the world. "Your Majesty controls only eleven of the people in the world. The common people are willing to help Your Majesty and take the remaining ninety." From this moment on, history was completely rewritten. Blast furnaces smelted hundreds of steel, black gunpowder blew open city gates, Mo Dao formation crushed Macedonian phalanx, and the Great Qin fleet crossed the Pacific. When the Roman legions encountered this black iron stream on the east coast of the Mediterranean, they did not know that what awaited them would be a dimension-reducing blow spanning two thousand years. This is the hard-core farming of science and engineering men, and it is also the global fantasy of an eternal emperor. Wherever the sun and moon shine, they are all the land of Qin; wherever the rivers and rivers reach, they are all the concubines. When "the sun never sets on the Qin Dynasty" turns from a slogan into a reality, how will the monarch and his ministers face the governance problems caused by the excessive territory? Will that huge empire that started in Xianyang eventually sail to the sea of stars, or will it be destined to prosper and then decline? Open this book and witness a magnificent civilizational expedition.
