Love History Caused By Willful Negligence - Chapter 83Vol. 2 :

The Prea gods, who saved humanity from living as slaves to other races and established the human empire, passed down their bloodline. Those who inherited their blood were born with magical talent and could become wizards. After thousands of years, the empire fell, and the world became ruled by great masters across different regions.He was a young man who grew up with his mother, never knowing who his father was. Though he possessed tremendous magical abilities, he lived as a shepherd in a rural village. Now he ventures out into the world to discover the secrets of his bloodline.

In the City of Crime, one law stands above them all: Only the strongest can live.

In the Solarian Empire, people were divided by their blood. The nobles enjoyed their life in wealth, with fine wine and amazing food. They reigned supreme over the commoners. The only reason they were able to do this was that they had knowledge of the most powerful force in the world - magic. The nobles controlled their knowledge from easily going to commoners, making it harder for them to learn magic.

Leo, a young orphan in Solaria, had an incredibly powerful affinity for magic. He didn't even know about it because he could never learn magic- he was too poor to try and learn from any magic academies. He was just trying to survive the streets of Solhaven until he found the lost tome of the Arcane Emperor.

"I can beat a 7th Circle Mage."

"Wow! You must have trained for many decades. How old are you?"

"17."
