Chen Shuo traveled through time and became a death-row alchemist, facing immediate execution. He used modern knowledge to create a "miracle" (using simple chemical knowledge to create colorful smoke), which gained the first attention of Qin Shihuang. Immediately afterwards, Qin Shihuang was attacked by assassins in the spring at the foot of Mount Li. Chen Shuo used modern security thinking to set up defenses and fought tooth and nail to rescue him. He completely won his trust, was named a permanent official, and was qualified to participate in state affairs. Chen Shuo then used the system to initially build a team, saw through the assassination plot of the old nobles of the Six Kingdoms, accurately cracked the loopholes in Qin's laws, and began to participate in formulating a specific plan to unify weights, measures, and writing. His master-disciple/monarch-subordinate relationship line with Qin Shihuang is gradually established in this volume.
