I Broke the Space Barrier Myself and Came Out Already Invincible.

Because of a bug in the system, I was trapped in this hellish place for 3,000 years! In the past 3,000 years, I have been fighting those damn monsters all the time, died countless times, and been resurrected countless times. Now, I have finally come out, but only 10 years have passed since the Earth. After 10 years, my attributes have been maxed out, including strength, speed, and combat skills. I feel like a beast that has been locked up for too long, and I can't wait to find a place to release it. Now, the outside world is invaded by monsters, so let me end it all! I'm here to save this world from monsters! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
