I Broke Through the Spatial Barrier Myself and Emerged Invincible

A bug in the System trapped me in this hellhole for a full 3,000 years!

For all those 3,000 years, I fought those damned monsters nonstop. I died countless times and came back to life countless times.

Now I've finally made it out, but only 10 years have passed on Earth.

Ten years! My stats are already maxed out. Strength, speed, and all those combat skills. I feel like a beast that's been locked up for too long, desperate to find somewhere to let loose. Now that monsters are invading the outside world, let me put an end to it all! I'll save this world from the monsters ravaging it!
