What sort of death you talking about? Tragic: sacrifices self to save the world death. Peaceful: dies of natural causes surrounded by his family death. Pointless: just dies in a ditch somewhere death.
A Monster Who Levels Up MC dies but is not dead even tho the MC died. No ancient times, no cultivation tho. But it is Korean...
The Living and its sequel The Hunted, both by Matt de la Pena. Both are books, not novels though and not in ancient times or cultivation.
Not sure if it's exactly what you're looking for but I Am a Magic Sword ticks most of your boxes. It's a typical Chinese cultivation universe except the MC plays the role of the golden finger for the real protagonists of the story, the wielders. This means that the protagonist that you've gotten used to and invested in can and will just die, sometimes not even in a dramatic way but they just encountered someone beyond their skill level and died.
