One Piece - I Am A Different Luffy! - Chapter 505 - 503 - Prison Project.

The story revolves around Charles Karino, a Levaamu Empire mercenary aerial pilot who mans the twin seater reconnaissance seaplane Santa Cruz. One day, he receives a preposterous assignment: to fly solo over 12,000 kilometers of enemy waters to protect a girl named Fana del Moral. Fana happens to be the next in line to the empire’s throne and a girl possessing beauty “equal to 5,000 beams of light.”

This is a standalone book. There’s another series under the name “To Aru Hikuushi e no Koiuta” (Love Song for a Certain Pilot) set in the same world, but in a completely different place and with different characters.

- Description from Novelupdates

When Alex woke up, he discovered he had transmigrated into the body of the ultimate villain of a cultivation novel, the Saint Lord of the Hale Family.In the original story, he was nothing more than a tragic tool, existing solely to be exploited by an overpowered male protagonist. No matter how fearsome his cultivation or how supreme his authority, his fate was to endlessly hand over treasures, opportunities, and women, until he was finally discarded and destroyed.Among those women was Isolde.She was personally nurtured by Alex from childhood, raised with the vast resources of the Hale Family. Rare heavenly materials, divine techniques, priceless treasures, she lacked nothing. Cherished as the apple of his eye, she owed Alex and the Hale Family a debt beyond repayment.Yet all of that was overturned by a single bowl of plain porridge.Deceived by shallow warmth, Isolde ignored decades of kindness and willingly severed all ties with the Hale Family in order to join the male protagonist’s harem.That was only the beginning.Later in the novel, she personally assisted the male protagonist in killing Alex and participated in the complete annihilation of the Hale Family's elders, disciples, servants, and even newborn infants, none spared.When Alex first transmigrated, it was precisely at the moment this adulterous couple stood before him in open defiance.Emboldened by years of indulgence, Isolde confidently made her demand, certain that Alex would forgive her as he always had, no matter how grave her betrayal.But this time, the ending changed.Alex spoke calmly, decisively and ruthlessly:“You may leave, but leave behind the Seven Orifices Divine Heart your family bestowed upon you.”
