I’m Studying Creation in Another World, Not Trying to Destroy the City

[Urban + Transmigration Between Worlds + Some Feel-Good Power Fantasy]

His arm was once severed, and he spent years down on his luck. Then, by chance, he gained the ability to transmigrate to another world at will. From then on, his body grew stronger and his severed arm regrew...

Watch as he bides his time, then overwhelms modern technology with nothing but his physical strength, and summons an army of the undead to conquer the global federation...

So what if the federation's crown prince is arrogant beyond measure? I will repay the old grudge over my severed arm and my family's blood feud a hundredfold.

Even the federation's empress will have to kneel and sing my praises when she sees me...

Note: This is not a reborn story, and it has no cumbersome stat screens, making it easier to enjoy as an audiobook...
