From the Start, Ranking the Four Great Inventions for Qin Shi Huang

[The novel From the Start: A Historical Review for Qin Shi Huang and Emperor Wu of Han is now underway.] [A different kind of content and perspective.] Recently, one line about Qin Shi Huang has been trending on D Station: My handsome, heroic ancestor, standing 1.98 meters tall! What's wrong with giving him an elixir of immortality! There may be no elixir of immortality, but the Four Great Inventions are on the table. Jian Banxi had a deep interest in history and often wondered what might happen if she could change the past. So she made a special video titled What If Qin Shi Huang Had the Four Great Inventions? The video was bound to the sky screen System and began playing throughout the dynasties. Thus, as the currents of history flowed onward, branches full of infinite possibilities began to unfold. Episode One: A Closer Look at the Unification of Writing, Paper, and Printing [This inevitably brings us to the achievements of our eternal First Emperor's great empire...] Ying Zheng: "Keep going. I like what I'm hearing." Liu Che: "Hah." Li Shimin: "I wonder how future history books will describe me." [...Unfortunately, the Qin dynasty fell in the hands of its second emperor.] Ying Zheng: "..." Liu Che: "Pfft." Li Shimin: "Still, Qin Shi Huang left a lasting mark on history." Episode Two: A Closer Look at Gunpowder, One of the Four Great Inventions [First, we have to thank all those emperors who sought immortality, took elixirs, and ended up killing themselves. In particular, Qin Shi Huang Ying Zheng, Emperor Wu of Han Liu Che, and Emperor Taizong of Tang Li Shimin.] Ying Zheng: "..." Liu Che: "..." Li Shimin: "..." Zhu Yuanzhang: "Hahahahahaha." Episode Three: The Compass, One of the Four Great Inventions [If Zheng He had taken not only a compass but also a world map on his voyages to the Western Ocean, he wouldn't have had to worry about missing the crops of North America. Then the Yongle Emperor Zhu Di could have accomplished even more.] Zhu Yuanzhang: "...The Yongle Emperor, Zhu Di?" Zhu Di: "...The sky screen has done me in!" Jian Banxi never expected the video she had uploaded on a whim to become popular. Her fans even left comments under all kinds of historical titles, acting just like the people they were role-playing and getting into character to argue with each other. It was so much fun. ●●● Notes: The planned topics include inventions, agricultural crops, the evolution of weapons, border defenses, Silk Road routes and sea lanes, and people's livelihoods and labor. Each topic will also branch into many related subjects. The videos will influence infrastructure in different dynasties indirectly, through immersion. Related topics will also be woven in, each with its own central theme, so this won't be a simple historical rundown. P.S. All dynasties are parallel timelines. ●●●●●● Theme: Advancing social development
