Reborn as Li Yuanxiao, the younger brother of Li Shimin, he wants nothing more than to be a tech-obsessed prince. Unfortunately, his imperial brother is always trying to dump his responsibilities on him:
"Fifth Brother, I'm going to personally lead a campaign against the Turks. You handle the court!"
"No way! Court bickering is exhausting."
"Fifth Brother, I'm heading east to inspect the people's lives. The government affairs are yours!"
"Not doing it! Don't ask me to cover for you while you sightsee."
"Fifth Brother, I'm going to reform the finances. You go clean up the bureaucracy!"
"I'm busy! I haven't finished improving my curved-shaft plow."
Until one day, Li Shimin sighed as he held his empty private-money box:
"Fifth Brother... If we don't find a way to make money, your big brother will have to put his drinks on credit."
Li Yuanxiao finally looked up from his piles of blueprints. "Well... I suppose we can talk about that."
Horseshoes, the steel-casting method, white sugar, colored glass... One cutting-edge invention after another appeared, and the imperial treasury visibly swelled.
Delighted, Li Shimin pressed his luck:
"Fifth Brother, you see how arrogant Goguryeo is, and Japan..."
Before he could finish, Li Yuanxiao sprang to his feet, eyes gleaming:
"Your younger brother accepts the order! I'll go deal with them right away!"
Li Shimin: "???"
I was just going to ask you to cover for me so I could go myself!
[A prince who only wants to develop technology, is forced to become a tycoon, and gets excited whenever he hears about war vs. an emperor brother who just wants to retire]
Overall very good.
It's okay, but there are some details. When answering questions from ministers, you should call yourself the king.
