Chaotic Craftsman Worships The Cube - Chapter 50

I became a heroine who dies during the protagonist’s awakening event.

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?

Earth Online – a virtual MMORPG that takes place in the future year of 2190 – a game that everyone will bet their futures on. Set in a map that is ten times the size of real-world Earth, players battle for supremacy in the first game to feature personal adventure, territory construction, and grand warfare. For every death you experience in the game, your level would drop back to zero. Ouyang Shuo, an above average player, suffered the ultimate betrayal. For merely a piece of equipment, his sworn brother betrayed and backstabbed him. This time, after he reincarnated in the game, Ouyang Shuo swore to exact vengeance.
