Good point, if He is around 60 biological years old now and if he was around 10 a 1000 years ago than by math we can estimate that for an oni and dragon hybrid's 20 years will only be about 1 year in their age standards this means wu is 1200 years old and he should live from 400 to 600 more years.

See doesn't this make sense this is a pretty good way to use math so It makes mathematical sense Wu would still be alive.

This also suggests the lifespan of an Oni and dragon hybrid is around 1600 to 2000 years.

Agree, this makes perfect sense.
