I am chasing a rough man in the 80s - Chapter 115: This Life is Too Short, The Next Life is Too Long

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?

“The True Form Of Order is chaos, It is a tale as old as time itself!”Since Dungeons began appearing around the world, things have changed. The world has evolved, letting dungeons alter the genetics of humans, giving some of them abilities and powers that no ordinary person would have.These abilities were called magic, and the ability to use them or even control them was called having mana. Almost 80% of the world’s population has gotten this ability. When a person who awakens their magic is seen, he or she will be taken for evaluation. To see their strength, there were strong and dangerous warriors who had to be used to keep the dungeon at bay and make sure that nothing happened to the world.Amid all this chaos, Darius Winters, a typical loser trying to make sure he would make enough money to pay for his sister's treatment, joins a guild on a raid. When his life is changed, Darius gains a powerful system, and he can get stronger than he was; the system makes him potentially the strongest warrior in the city.But he chooses to hide from the spotlight and take care of his sister. But how long can he keep up with that? when he is thrown in the middle of a brewing war between divine beings
