Behind the Scenes, Helping the First Emperor Rule the World

Protagonist: Long Shiheng (a time-traveler, sly and cunning, with a vicious tongue and a fondness for complaining. He comes with the [Huan Xia Dragon Cauldron] system and hides the secrets of time travel and the system. He claims to be a "lone man from a poor family", but in fact he is the manipulator behind the scenes who eats pigs and eats tigers) Core Line: Instead of following the old path of "crushing the Six Kingdoms by force", the three pillars of "spy network infiltration + technological blockade + popular support to instigate rebellion" are used to assist Ying Zheng. He first disintegrates the foundations of the Six Kingdoms, then unifies them, and then leads the Qin Dynasty across oceans and continents to create a global empire. The monarchs and ministers pit each other on a daily basis, from testing each other to trusting each other in life and death.
