Those two individuals unexpectedly self-destructed their physical bodies and their intrinsic Pure Yang True Treasures just now.
Although their primordial spirits remained, allowing them to continue surviving, the heavy injuries they suffered meant that their future Dao paths were completely severed.
Even their lifespans would greatly diminish.
Under normal circumstances, the lifespan of a Soul Formation Heavenly Lord was approximately around 5,000 years.
If combined with various life-extending treasures, theoretically, it could extend up to 9,999 years.
However, for the current Xiao Shenji and Daoist Shang Tong, their remaining lifespan, at most, wouldn't exceed a thousand years.
Moreover, unless they possessed life-extending treasures specifically designed for primordial spirits, regular life-extending treasures wouldn't have any effect on them.
