The Mightiest Little Master of Metaphysics - Chapter 9: Taken to the Hospital for a Brain Examination

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?

Life is often full of curveballs. It likes to keep you on your toes.But what can a regular guy do when he gets booted to a world full of gods, dragons, devils, angels, yokai vampires and everything in between with only the clothes on his back and a reality-bending gacha behind him?His best apparently.

In a world without gods, where the laws of magic are written by the mages themselves, balance is fragile, and darkness reigns. Multiple dimensions surround it, watched by beings with dark and greedy intentions. This is a magical universe, unstable, marked by constant changes, betrayals, and bloodshed. At the center of it all, an ordinary man emerges, carrying a biochip capable of deep analysis and data recording. With it, he embarks on a relentless journey of genetic enhancement, seeking to ascend beyond the limits of existence. Without divine protection, without charms to shield him or overwhelming powers, he must survive in a world where threats are ever-present, and the fight for survival is relentless. Here, the only rule is to conquer or be consumed. A dark fantasy filled with dangers, evolution, and the relentless pursuit of supremacy.

He was supposed to transmigrate to a magic world, but due to an accident, he ended up trapped in a massive library. The system assigned him a task: for every book he read, he would be rewarded with mana stones, until he finished reading all the books. A trillion years later, Daniel finally finished the last book! [Ding, detecting that the host has finished the final book. Calculating system rewards.] [Ding, reward calculation complete. Dispatching rewards. The total number of mana stones the host has accumulated: 99999999...9999.] “Damn, am I that rich now?” [Ding, detecting that the host has completed the task. Loading world...] ... Goddess of Fate: “Daniel, my divine realm needs expansion. Could you sponsor me with some mana stones?” God of Storm: “Daniel, the divine punishment is about to descend. Could you lend me some power to help me get through it?”
