Han Seojun was a loser, frail and barely more than skin and bones from a life of poverty, was raised by his hardworking mother with no knowledge of his father. At 18, he inherits the Ancient Infinite System, a power passed down for generations from Goddess Zyraena, The Former Echidna (Goddess of Monsters).

The system transforms his weak body and improves their lives. Just as Seojun is about to take his dream veterinary exam, he's suddenly summoned to the Abyss Realm, a brutal world where only the strong survive.

After 500 years of battle (About 69 Chapters) Seojun finally took back the Realm and returned to Earth.

But the world had changed. Dungeons and monsters are rampant, and people now possess skills and classes granted by a system called global system Where Earth transformed A Game into Reality.

People granted is known as the Awakeners and Seojun, protected by his Infinite system, rejected the global system. 

With the world so different, Seojun then took a role of a professor to live peacefully but instead obtain a hidden profession.

Infinite System Inheritor Return From The Abyss

"You've earned my respect, Seojun. Your strength and resilience… It shows you're worthy of standing among the greatest in this realm."

Seojun nodded, still a bit surprised by the compliment. "Thank you. I'm glad to have your respect."

Nerathiel gave a rare smile and placed his arm over Seojun's shoulder in a friendly gesture. "I look forward to our next fight. This time, I'll go all out."

Seojun smirked, meeting his gaze. "And I won't lose, Nerathiel."

Nerathiel chuckled, "Good. When I fell into the Abyss, some of my power was sealed, but once I've recovered everything, we'll see what you're really made of. I look forward to that day."

Seojun smiled back. "Me too. It'll be a fight worth remembering."

The conversation was a peaceful break for Seojun. It was unexpected to see Nerathiel being so polite, but it made Seojun feel more at ease.
