One Piece: My Crew is from Other World - Chapter 125: Akatsuki vs. the Seven Warlords of the Sea — Ryuunosuke Strikes Alone!

By the coast, a hundred-meter Star Gate shimmered with flowing light.Beyond the Star Gate, an army forged of steel stretched as far as the eye could see.Above the Sky Dome, squadrons of fighter jets streaked across, weaving an iron curtain.In the distant ocean, scores of aircraft carriers, destroyers, and frigates dotted the seascape, ready for action.All cannons were aimed at the figure who emerged from the Star Gate.“In the name of the Federation Command Center, I order you to stand down, or what awaits you is total war,” said the voice.“War?”Gu Jinlai took a step forward, and his form swelled against the wind, in an instant growing from less than two meters tall to a colossal Chaos Demon God thousands of kilometers high, emitting the brilliance of a white dwarf star from his being, his own gravity causing thunder and lightning, as well as tsunamis and tides within a thousand-mile radius.He looked down...At the war weapons that seemed like toys.He reached out, and a hydrogen bomb fell into his hand.Within him, the electron-degenerate star core released Helium, Helium elements expanded, and the terrifying high temperature instantly caused Deuterium and Tritium, Hydrogen's isotopes, to fuse, the energy bursting forth, forming a blazing white brilliance on the ocean's surface that was like igniting a sun.Before this sun's energy could be released, he clapped his hands together, and the dazzling white, mixed with heat in the billions of degrees, was compressed and sealed within his palms, not a fragment escaping.“I think, you should choose peace.” he suggested.

The figure of the Armada seems to be still riding the wind and waves in the Atlantic Ocean, and the gold of South America still seems to flow in continuously. As Alfonso from the Bourbon family returns to the Royal Palace of Madrid where he was born, the story begins here…

- Description from novelbuddy

Harry Morton was born in an age where magic and mana ruled everything.

He was unable to awaken his affinity and to make things worse he was born with a broken mana core foundation which meant he would never be able to create or develop a mana core. Since he couldn’t create a mana core, he would never be able to draw mana—not even the slightest strand.

He was the first person to be born without a mana core foundation, the only one with the inability to draw mana. Due to this, he was regarded as trash by everyone: his parents, his friends, the society and even the academy he attended.

It was until one day, during a mana beast attack when he almost lost his life.

He saw a strange white line rapidly moving downwards, towards him. Unbeknownst to him, the white streak went into his body.

When he woke up the next day, a strange message appeared in front of him.

DING!!
