He was arrogant and taciturn, and was banished to Qinqiu on the border of Qin State. This place is deserted, with Xirong watching outside and no food, grass or soldiers inside. Without the blessing of a golden finger, he only relied on what he had learned in his heart and his iron-blooded skills to dig canals to divert water, open up wasteland, and build cities and fortifications. From a mud house to a majestic city of thousands of feet, from a hundred households of refugees to an army of ten thousand chariots, he used infrastructure as a blade and people's livelihood as a shield to resist the Xirong, contend with Wei and Han, and compete with the princes in the true war of the Warring States Period. The lonely and arrogant person does not seek to join the group, but only seeks to disrupt the chess game in the world with the power of one city, and finally becomes a city-building hero in the chaotic times of the Warring States period that makes the seven nations fear him!
