After The Abyss Dragon Woke Up

Shi An is the last Abyss Dragon in the world. Since he was bored, he decided to go into a deep sleep while hugging his treasures. After fifty thousand years of satisfying slumber, Shi An opened his eyes only to discover that he had become a weak human with short hands and legs.
He glanced down at his mysteriously downsized body and then lifted his head to look around his empty cave. “……” Where is my powerful and majestic body? My big tail? Most importantly, where are my treasures?!
After thousands of years of hard work, sleeping just once has sent me to square one.

In the year 2202, the conflicts between humans and monsters are becoming more and more intense. Although the monsters are strong, the fantastical species that used to rule the continent have all but disappeared.
Shi An, the Shi family’s youngest son, is Mage Academy’s infamous mage who has no magic power. Each student’s magic power is measured at the beginning of the school year. Shi An looked at the three destroyed magic detection equipment and innocently asked, “Eh? Are these equipment’s quality not very good?”
During actual combat training, low-ranked monsters fled before Shi An could get close. Shi An looked at their fleeing figures and innocently exclaimed, “Yay, lucky!”
Everyone else was speechless. “……?” I believe I am dreaming.

Mu Heng——human species’ strongest mage——is the only remaining human who bears the noble dragon slayer bloodline.
He coldly and arrogantly said, “Dragons? Extinction is their best outcome.”
A long time later, Mu Heng turned his head back to look at the dragon cub reclining on the piles of treasure. Mu Heng withdrew his gaze and leisurely asked, “Are there any other jobs? I want a well-paid one.”
Extinction is out of the question now. As a matter of fact, I can only earn more money so that I won’t get kicked out of bed at night.
