In the Fantasy World, I Can Be Invincible As Long As I Sleep

I was actually pushed into the most dangerous abyss in the world by someone who claimed to be a companion, and I almost died?

As a result, he awakened a super super powerful ability that makes him invincible as long as he sleeps?

From then on, you lived a happy life surrounded by beautiful girls, eating and sleeping every day?

Well...if this is a dream, I hope I will never wake up from this beautiful dream...

Snore...
