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.

Infinite System Inheritor Return From The Abyss

The training session finally came to an end. Sui was panting and looked tired, but there was a spark of determination in his eyes.

The system announced, and in an instant, Seojun teleported in front of Sui. He kicked off the nearest Silver-Scale Crocodon, sending it crashing into a tree with a loud thud.

Sui tried to catch his breath, "K-Kyuu… Master! How did I do?" His voice was shaky, and he could barely speak properly after all the training.

"You did great" Seojun encouraged, giving Sui a gentle pat on the head. "Your dodging improved a lot."

"Really?" Sui perked up, a little excited despite his exhaustion. "I-I thought I messed up when I tripped earlier kyuu…"

"Everyone makes mistakes, Sui. What matters is that you kept going and learned from them," Seojun replied, smiling. "You dodged all the attacks."
