Qi Tong traveled through time and was the son of a small official in a border town. He used modern knowledge to solve local problems (improved farm tools, simple epidemic prevention, grassroots organizations), which attracted Meng Yi's attention. Meng Yi visited here on his eastward tour and was attracted by the protagonist's "novel remarks", and the two became allies. The protagonist presented a simplified version of the world map and the concept of the "Great Qin Earth Empire", which attracted the attention of the First Emperor and was transferred to Xianyang.
