Learning Martial Skills

Tang Yin had thought long and hard before deciding to Devour several tens of billions of Low-grade Spirit Stones and a billion Mid-grade Spirit Stones which were all of the Low-grade and Mid-grade Spirit Stones that he owned.

The main reason for this was the new innate ability of the Heaven Devouring Abyss Physique, Passive Regeneration.

The Passive Regeneration would require Abyss Qi to passively regenerate Tang Yin's body.

Even though there was a colossal amount of Abyss Qi stored away inside the Heaven Devouring Abyss, Tang Yin still felt uneasy.

If he ran out of Abyss Qi during a critical battle which determined his life and death, Passive Regeneration would stop functioning. This meant that he would not heal and would continue to accumulate injuries until he died. His focus would also be distracted since he would have to pay attention to his injuries which would only further speed up his death. It was simply too huge of a risk.
