Lin Mo, a modern engineer, accidentally traveled through time and returned to the border of Zhao State at the end of the Warring States Period, where he became a fallen scholar. Just on the eve of Qin Jian's sweep across Liuhe, wars broke out and people died of hunger everywhere. When he was about to die, he activated the "Cornerstone of Civilization" system - no physical gifts, only scientific and technological knowledge spanning thousands of years, and advanced technology caused civilization to backlash, and the road to change was startling every step of the way.
In order to survive, he made water purification devices, improved farm tools, gathered refugees to build a technical commune, and used compost rotation to solve the problem of food and clothing. With the help of simple gunpowder and lever ingenuity, he emerged in troubled times, and was eventually called to Xianyang by the Qin Dynasty.
Since then, he has used technology as an edge to break down traditional barriers; based on knowledge, he has built a blueprint for a prosperous age. Improve Qin's crossbows, innovate water conservancy, build craftsmen's schools to educate technocrats; promote standardized production, create a battlefield medical system, and help the Qin cavalry sweep across the six countries and dominate the world.
In the court, he dealt with the debate between Confucianism and Legalism; in the palace, he used cowpox prevention and health monitoring techniques to rewrite the fate of the First Emperor. From blast furnace steel-making to paper-making and sending letters, from the prototype of steam to the sprout of the telegraph, Lin Mo worked step by step to lead Chinese civilization to break free from the shackles of history.
When the Xianyang Bell Tower rings a new bell, and when the experimental railway extends into the distance, this guide from the future will eventually carve an immortal monument to the advancement of civilization on the land of Great Qin.
