Synopsis: Tags: [Game-World Crossover] + [Sovereignty Farming] + [Luck Mastery] + [Undead Scourge] + [Inter-Species Conflict] + [Heroic Battles]This is a world where games have invaded reality.Every year, students turning 18 awaken to a job change.One person crossed over and became a Necromancer.Relying on a luck-based talent that made wishes come true and a legacy from Mother Earth, this person rapidly gained power.While others gambled on skill mutations, summoning variations, and the chance with endless resources,he simply needed to shake his talent and use the least resources to obtain everything.With an undead frenzy, he broke through the blockades of the other nations on Blue Star, making his empire great again.With the undead scourge, he wiped out the decayed porcine dynasties within realm territories and became the new Realm Master.In the name of the Dead Spirit Overlord, he waged war on the Battlefield of Ten Thousand Tribes and ascended to the throne of the Demon God.

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?

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?
