Greetings, Ninth Uncle - Chapter 109: Miscarriage (III)

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? Or will he succumb into a conspiracy lurking within the country's borders?

It always starts with an accident.That’s how all these stories go. One moment, you’re minding your own business, and the next, you wake up in someone else’s body. For Caspian, his accident started earlier than he even knew.Maybe it began when his sister got him into romance novels? Or when he started really sympathizing with the villains at the ends of books? He’d never know. It was too late to worry about it now.For now, he had to find a way to fix this nightmare, or rehabilitate his image, all while trying to free himself from the fate set out for him. All because of the damn “gods” who he'd cut a deal with.These were the only two options he had available, and he wasn’t sure he could succeed at either. The man he had taken over for had been…a true piece of work. And the secret villain of the book he had been reading before he passed.It had been a harem novel. A reverse harem novel.He was trapped in a huge ass CASTLE with a bunch of men who hated him because he was taking affection and time away from their shared wife. All Cass wanted to do was be a good person, not mess around with this poor woman and her far too handsome husbands.But why would no one leave him alone? Was he too suspicious? And why, after going out of his way to avoid them like they had asked, did they keep pestering him?And where did the heroine go?How was he going to manage three, handsome men without the heroine?

For the crimes he commited, Theo was executed by the exile to the outlands, beyond the limits of human civilization, where the S-rank monsters reigned supreme.Yet, rather than feeling despair, guilt or anything else... Theo was excited.He had no memory of comitting any of the crimes he was sentenced for. Or, to be more precise, he had no memory of doing anything in this world other than sitting in the prison-coach as it drove to the edge of the civilization.And how could he not, with the system prompt hanging out in the corner of his vision, promising to activate only once he set foot in the outlands?Turn the world into blocks... and mine them out. Craft whatever your heart desire. Construct, automate, explore and exploit!But when you hear the boss music kick in...Do you run, or do you stand your ground and fight?!And what if, while you play minecraft... Others play game of thrones?

Whenever our ship encounters a tenth-level storm, my comrades-in-arms will not have the slightest worry, because they know that I still have me on board.
