This is a group portrait of the late Qin Dynasty from the perspective of a time traveler. It has no system and is not a brainless novel. It is more like a late-night chat with historical figures. If you like those magnificent and murderous years, you might as well come in and sit down. I will try to find a balance between humorous comments and serious historical facts, reproduce every major event, and present a flesh-and-blood Liu Ji, Zhang Liang, Xiang Liang and Xiang Yu. If you prefer this style of "talking while deducing the general trend of the world", you are welcome to follow up; if there are any mistakes, please feel free to point them out - after all, Liu Ji, who graduated from three history departments, often has deviations in his script notes.
