The God Of Power - Chapter 147 - 146:

Once upon a time, a hero had been summoned to a different world in order to defeat the demon king. After the war stretching 3 years ended the commendable hero slew the demon king. And he was forcibly deported back to earth after being dismissed.

Such bullshit!

Elves in addition to beast race, dwarfs and demon race. Even though I wanted to make a harem in the different world I saved! My dream will not come true on earth, where there is no magic at all. Thus, the hero returns on his own. Without the blunder of being extradited to earth this time, he will build a harem of his own in a different world.

“It’s finally here,” said the man with the sword in an echoing whisper.

“The Tower of Choice, the last 100 floors!” the band of five exclaimed in unison.

Angelica came down from the altar with a dull look, seemingly annoying.

Then we looked around.

“I tell you once again, but you’ve had a lot of trouble in the meantime. I couldn’t have climbed to the 100th floor alone without you.”

Thud!

One by one, they fall to the floor.

Angelica’s dagger pierced my neck, and I felt a darkening in front of my eyes with a tumultuous rage. My awareness faded, from my senses, from everything else. After that, everything was eroded by profound darkness.

An ineffable rebirth, taking advantage of a mystical magic cube that was produced from rebirthing to pass through various worlds(anime, novel, movie, games, etc), collecting whatever I want to obtain!
