When home is a universe away,
when civilization has been lost and shattered,
an ordinary college student transmigrates to a world of lost civilization, accompanied by a drifting iron coffin and a bewildered heart.
The transmigrator, the pioneer, the loyal AI, and the basic principles together define what it means to be "human."
The miracles wrought on a grand scale by unknown magic, the chasms formed by time and technology, the enemies lurking in the dark, and the barriers between civilizations.
When the fires of civilization are rekindled, they become a calamity that sweeps across the cosmos.

In short, this is an original sci-fi story about drifting in a derelict ship and mining in peace (?) .
