One Piece: Madness of Regret - Chapter 31: Rain, Storm and Whales. Again!(4)

William and his college class are ripped from Earth and thrown into Aethel, a world on the brink of collapse. Everyone gains incredible magical powers – except William. Mocked and underestimated, he’s an outcast among heroes. But William has a secret: an SSS-ranked skill that lets him travel to Aethel’s past. Learning lost magic from ancient masters, he’ll surpass his classmates and become the true savior Aethel needs. But can he overcome the dangers of the past and present to forge his own destiny? While others studied about the first mage, William could go back in time and see the first mage himself! While others dreamed of seeing a dragon, William could go back in time, hatch a legendary dragon egg and turn it into his puppy. While others used common materials to craft their items, William could go back in time and mine materials that weren’t find anywhere in Aethel anymore. Is it unfair? Perhaps, but William was not the type of person to not use the powers the universe gave him.

This is a world dominated by beastmasters.

The swaying star dragon bird above the nine heavens.

A lightning elf wielding a long whip in a thundercloud.

The giant whales of the vast seas are entrenched in the mountains and seas in the depths of the ocean.

The ghost of the flame shadow jumping in the unquenchable candle.

Ji Feng flipped through the Book of Starry Sky in his hand and created one myth after another in this vast world of beasts.

Embark on a path that is unique to its own creator.
