Upon hearing Ma Long's words, Li Hu slightly frowned; he didn't like his friend talking in such a defeatist manner.
Su Tu understood Ma Long's meaning; after the Martial Arts Dao cultivation falls to Falling Leaves, Opening Martial Bone, condensing Martial Intent, the flesh receives Martial Dao augmentation and support.
It can withstand the wash of time, the flesh remaining immortal for three hundred years, but the heart and spirit differ; the flesh being immortal doesn't mean the heart and spirit are undying.
The Suffering Tier Heart Life can reach 150 years, but if before the heart life runs out, one cannot cross the Sea of Suffering to reach the Mortal World, then the heart and spirit will be extinguished.
