Modern young man Qin Yu accidentally obtained the space-time bridge system and traveled through the Qin Dynasty. Faced with an unfamiliar time and space, powerful system capabilities, and the changes in the Qin court, he did not choose to claim hegemony alone, but made a decision that subverted the era - handing over the system to the country.
From then on, he became a bridge connecting two eras, using modern knowledge to inject new vitality into the Qin Dynasty, and using the resources of the ancient world to nourish China's scarce items. Under his promotion, he built water conservancy, improved agriculture, strengthened military armaments, and promoted people's livelihood. The trajectory of history was quietly deflected. In the court, he discussed law with Li Si and talked about military affairs with Meng Tian; among the people, he taught people how to read and passed on skills to future generations.
When the power of the system combines with the will of the country, and when modern wisdom collides with ancient civilization, let's see how he assists China and Great Qin in creating an unprecedented prosperous era in the era of magnificent conflicts. This is not only a time-travel legend of one person, but also a civilization relay spanning thousands of years.
