The Tyrant's Max-Level Dragon Bride

Aurora is the last true dragon of the Abyss—and its most ferocious world-destroyer.
After an unexpected transmigration, she finds herself in the body of a supposedly useless bride sent as a substitute to marry the empire’s unhinged tyrant, Alexander. Armed with a body that grants her absolute immunity to physical harm, Aurora plans to keep a low profile and live a carefree life in the imperial harem.
However, Alexander is afflicted with an exceptionally vicious curse known as the “Death God’s Curse,” and he spends every day devising new ways to uncover her hidden identities.
Thus begins a fated bond forged by one inescapable truth:
I am your one and only salvation.
