Yu Chen was just an ordinary student, quietly supporting his mother and younger sister in a world that never stopped demanding more. But everything changed the day the skies darkened, and an unknown planet appeared near Earth.

A devastating infection swept the globe, and one in every three humans became a zombie overnight.

As cities fell and chaos ruled, survivors awakened to strange powers through a mysterious system—a last chance to fight back against extinction.

But Yu Chen was different.

He received a unique class, unlike anything others possessed—granting him the power to create an Internal World, a hidden sanctuary where people could live, grow, and survive. With stats far beyond the average awakened and the ability to copy abilities from others, Yu Chen became humanity’s unexpected hope.

Yet, his goal isn’t fame or power.

His mission is simple: protect his family and build a new future away from this broken world—even if he must face monsters, betrayals, and impossible odds.

In a world where survival is a daily battle, Yu Chen will carve his own path—one built on love, strength, and the will to rewrite destiny.

Yu Chen slowly opened his eyes. His body ached, but he was alive.


"I'm… dead?" he muttered, unsure. But then he saw them.


The two zombies — the ones from before — were lying on the floor, unmoving.


"I'm alive," Yu Chen whispered, almost in disbelief.


He looked down at his wounds… and watched in shock as they began to heal rapidly, as if his body was regenerating on its own.


Then, in front of his eyes, a floating light appeared — a glowing screen of light.


"What is… this?" he said. "The system? I heard that voice before I lost consciousness…"

"Who's saying that?" Yu Chen asked aloud, looking around the empty classroom.

"What?! So a normal person can awaken a class just by killing goblins?" he asked, stunned.

The sound of cracking wood and an angry scream hit Yu Chen's ears. The door shook, and the groan of zombies echoed all around.


"I have to go. I need to save my sister. I don't even know if she's safe in the college…"
