The Lowest Rank Hero Returns to the Academy

[From the author of I'm not a Regressor & The Player who Returned 10,000 Years Later:]
The first time I realized I couldn't die was during a practical training exercise in my third year as a Hero Candidate. A monster had sprung from the bushes, its jaws clamping down on my neck with a sickening crunch.

'I came back to life somehow.'

That's right.

I came back to life.

I wouldn't die, even after hundreds and thousands of years.

I had survived.

I was the only one who survived.

“It all ends… now.”

After wandering for thousands of years, I thought I could finally put a rest to this grueling life...

"Dale! Dale Han! How dare you sleep in my class? You’ve got some nerve, kid!"

"...Huh?"

What awaited my long-lasting life wasn't a curtain call but an encore.
