[Starship development + technological civilizations + the Myriad Worlds + interstellar tomb raiding]
In his previous life, he was an immortal king of immense power who conquered the Myriad Worlds. By chance, he is reincarnated in a technology-driven galaxy as a powerless humanities student majoring in archaeology.
At a recruitment station, he has barely stated his major when the recruiter grabs him by the arm.
“We’ve finally found you! Our fleet needs talent like yours!”
He is shoved onto a suicide squad before he can make sense of what is happening. Then an accident awakens the sealed memories of his former life as an immortal king.
A steel hull?
Infuse it with spiritual energy and temper it into a unique bonded magical treasure.
A shipboard AI?
Imprint it with a soul-binding seal and refine it into an intelligent spirit core.
While enemy fleets are still competing over warp engines and the firepower of planet-destroying cannons, his warship has already laid out a Nine Heavens Thunder Array. At a single thought, it can teleport thousands of miles, and its hull can repair and evolve on its own when damaged.
From then on, the whole universe is abuzz with rumors: behind that mysterious starship that appears and disappears without a trace is a captain who has absolutely no regard for the laws of science!
