One Piece: Seaside System - Chapter 8: Marine Based -

An Ning transmigrated to a parallel universe in the year 1780, initially hoping to use his understanding of history to remain neutral and become a wealthy landlord, seeking neither fame nor recognition in the troubled times.However, it seems that the course of events has somewhat spiraled out of his control.'Respected General, we acknowledge no one but you,' said the young Captain with the surname Bonaparte.

Lin Qing He transmigrated into a novel and became one of its cannon fodders. The novel’s background is non-viable 1960s, a time of want to eat but nothing to eat and want to wear but nothing to wear.

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.
