I, Lin Yi, the nation's chief scientist, spent my whole life burning myself out in laboratories and over blueprints.
On the day I died, I had done right by my country and its people, but not by my parents.
I closed my eyes with a heart full of regret, then opened them again to find myself the third prince of a medieval empire.
Royal blood ran through my veins, and beside me lay the freshly approved document naming me heir to the throne.
I worked myself to death in my previous life. This time, I'm done pushing myself.
I immediately drew up a retirement plan: hand the throne to my younger brother, and choose a fief as far away as possible.
From then on, I'd farm a little, invent a little, and enjoy a quiet life.
Until I discovered...
My fiancée is a little girl with silver hair and violet eyes?
Wait, she's an adult? And one of fewer than five advanced mages in the whole country?
I absolutely have to marry her!
But trouble came one thing after another as soon as I reached my fief:
The nobles rebelled, and my little brother couldn't handle it.
The Church held unchecked power and even sent a holy knight to "purify" me.
The neighboring Orc Empire took advantage of the chaos, sending a hundred thousand troops to war at a moment's notice.
I only wanted to retire. Why am I even busier than in my previous life?
Still, maybe that's not so bad...
You have magic? I have physics.
You have the Church? I'll teach the common people to read and write.
You have swords? I have a complete blueprint for the Industrial Revolution.
By the time I came to my senses, steam engines were chugging, railways were running, and electric lights were shining.
I only wanted to live a lazy life, so how did I accidentally lead the world into the Age of Electricity?
