In addition to the spiritual energy of Zero, Ling Mo also Devoured the small amount of spiritual power from Ai Feng.
Under the circumstance where Zero could not even save itself, naturally, it wouldn't care about Ai Feng as a vessel, and during the struggle, it inadvertently caused great damage to his Spirit Light Ball.
This actually saved Ling Mo some trouble, allowing him to easily breach his instinctual barriers.
Now that these energies were damaged and lost the ability to resist, absorbing them turned out to be faster and with less loss compared to one whole entity.
However, after the energy merged into Ling Mo's Spirit Light Ball, it caused his Spirit Light Ball to shrink drastically.
During a bout of severe headache, Ling Mo felt as if his brain was being forcibly compressed.
Memories kept flashing by, even some things he barely remembered were dug out during this process.
Perhaps it was just a short dozen seconds, but to Ling Mo, it felt like several months had passed.
