Was reading 1 second invicibility in the game novel : https://www.novelupdates.com/series/1-second-invincibility-in-the-game/ then i remembered that i read something similar before where an mc was supposedly transmgriated to a game/novel where he was in a ship(with prisoners?) and he has a similar power where is immune for 1 sec or 1 attack cant seem to remember the name besides that
he has tp not invulnerability and the first chapters are not on a ship, might be remembering wrong about the ship part but its def not that
Sounds similar to I Fell into the Game with Instant Kill — MC wakes up in a game he was playing, where he's on a ship with other prisoners making their way to a prison—like the title suggests, he has the power of Instant Kill though, not invulnerability...?
