In Chang’an, my public persona is that of a kept man: uneducated, despised by the princess, and a useless prince consort.
In secret, I’m Yang Guang’s imperial grandson, Li Shimin’s secret weapon, and the only person capable of bringing two great empires together.
But my real identity is... a modern office worker who just wants to lie flat!
Unfortunately, my “System” won’t allow it!
To earn a little money from writing, I used the rewarded [papermaking] technique to print a few novels.
The result: the powerful clans fought tooth and nail to get the rights to distribute the paper.
Scholars across the land: “Young Master Yang ushered in a golden age of culture single-handedly. He should be our teacher!”
To get a new cooking pot, I used the rewarded [steelmaking] technique to smelt a little iron.
The result: the divine steel I made alarmed the Ministry of War, and I was appointed head of the Imperial Armory.
The Tang military: “With the prince consort on our side, conquering the lands of the Xiongnu is just around the corner!”
Yang Fan (in tears): “Wait, I only wanted to make life a little better. How did you fast-forward me to founding a golden age?!”
Li Er/Yang Guang (exchanging pleased looks): “My son/grandson has certainly lived up to our expectations!”
I just like your nonsensical and pure pleasure. Although the timeline does not match the official history, you said earlier that parallel time and space are different from the official history, so I will forgive you.
