Dumped by his girlfriend for being broke, killed in an accident by a truck, only to get transmigrated into a fantasy world as Lucien Goldveil, noble heir of a rich nobility in the kingdom of Edoria.He should be content since he was now filthy rich, but he couldn't, as this world was a world of magic where money without power was only a curse.What he would face next would only be endless conflict and the hounds looking at his wealth with those hungry gazes.---Ding[Debt Collector System has been successfully bound.][Detected failure to collect debt from target: Alchemist Devan.][Automatically extracting compensation of equivalent value…][Congratulations! You gained: Minor Mana Sensitivity (Passive), +1 Intelligence.]---Fortunately, his system came on time, giving him that glimmer of hope. Now, it all depends on his ability to exchange his vast wealth for power by playing his cards right.With the kingdom teetering on the brink of war and the Godveil family surrounded by hungry wolves, Lucien had no choice but to grow stronger and fast.Not to mention finding those behind the shadows hellbent on killing him, or those trying to kidnap him for his wealth. Wealth without power was a curse, and it was on Lucien to change it into a blessing instead.And those dungeons… Wait a minute—why the heck does this world have so many dungeons?

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?
