A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

The pessimistic and negative daughter of a concubine living in the ancient times thought – since life is so difficult, why should one invest serious effort in struggling to live?

The life of an ancient noble woman is often determined and controlled by her family. Moreover, one’s actions often implicate one’s entire family – thus, it is fairly common to see an unexpected calamity result in suffering borne by one’s whole family. Managing to live a good and successful life while retaining one’s dignity is simply too difficult to achieve.

Ah, living in the ancient times is simply too dangerous – we should all just sleep till we die.

In a world of magic and monsters, I carved out my own empire. Hellfire Studios - my brainchild, my legacy.It all started with “The Demonfather” - a blatant copy from my past life, sure, but this world had never seen anything like it. Humans, elves, dwarves - they all fell in love with it. Critics raved, audiences cheered, and suddenly, I was on top.But the world thought I was a one-hit wonder. They had no idea what was coming.I unleashed “The Lord of the Rings” upon them. The result? Critics were left speechless, fumbling for words to describe what they'd witnessedBut why stop at movies? This world was stuck in the past, so I dragged it into the future. I created computers, birthed video games, and watched as everyone from imps to elf elders became addicted to pixels and polygons.Still not satisfied, I turned to music. I crafted stars, produced hits, and soon had the entire realm dancing to my tunes.But even that wasn't enough. Comics, manga, cartoons, anime, novels - I introduced them all. I flooded this world with stories and art forms they'd never dreamed of.Before long, people weren't just consuming my creations - they begun worshipping me. They started calling me “The Lord of Entertainment.”
