The user will need to concentrate small bits of Yang chakra to cover their vital areas which are the necessary organs and the skin. When done, those organs will no longer age and will experience a placebo-immortality as they won’t age but can still die from vital strikes. Though the Yang chakra won’t stay forever and will normally last for 25 years and when that time would be used up, the user will instantly age which can possibly kill them on the spot making this technique a dangerous time if they were to let the Yang chakra get old.
