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.

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?

Of all the characters in this story, it had to be the son of a bitch!?Thanks to the courtesy of Truck-kun, I was transmigrated into the famous yet garbage novel, [Hero's Apocalypse].The character I possessed was a third-rate extra who had the [Talent] to 'plunder' other talents. Yet, as overpowered as it might sound, the conditions to fulfill a successful plundering were extreme, making this character truly befitting a third-rate trash.But that's not what's important right now—it's the fact that this man's role in the original story was his very death, and I opened my eyes after the original body just finished killing himself.“Fuck! Why did you attempt to sexually assault the Imperial Princess?!”Feeling livid, I strongly punched the mirror in front of me, knowing that as soon as I gained a new life through mysterious means, others would inevitably come to take it because of this bastard's unforgivable sin.But I wanted to survive...Motherfucker, can I do it?!

“On that day, Zach Harper died-” Or at least that was how it was supposed to be. I died. But there was good news, and bad news. The good news; I was reincarnated! Transmigrated into the World of Aethoria! Holy fuck, miracles do happen! But the bad news was, “Huh? What’s this?” ... [DING!] A New Quest has been issued:- Type:- SURVIVAL Name:- Quest To Becoming Stronger: Description: The {Great Calamity} is coming...Get stronger and survive. Duration-: ... Reward:- ... Penalty:- Death, ??? ] ... I had to survive.
