Tree of Aeons - Heroes and the Final Boss Fight

The story is about a boy entering high school, who answers a strange call from a public phone one night. The caller challenges him to a bet: She’ll remove the birthmark which he sees as the cause of so many problems, and he’ll have fifty days to win the heart of a girl he’d considered far beyond his reach. And with this, a very strange summer begins.

In her previous life, she died of hatred in a gray robe.

The former cannon fodder was reborn, opened the inheritance of the mysterious jade pendant, washed out the top meridians, and rose to the top in red.

Those who persecuted her, hindered her, calculated her, died! !

There is a jade pendant in hand, and countless treasures are detected, all of which are welcome. She frowned and looked at the man in front of her, and said lightly, “I’m sorry, I made a mistake, I took it wrong, and you can go.”

God knows when this man was taken over by her and hurriedly threw it away. “Don’t make trouble, madam, go home, you are the oldest in the family.”

"An accident. She's pregnant. How unlucky. She got pregnant in one shot!

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.
