Since the battle with the Insect Man Army began, Yi Lin kept his abilities, "Follow Like Shadow" and "Shadow Execution," active, closely following Mo Ren Di. Despite Yi Lin's Mental Attribute being on the verge of "Lock Breaker," along with the upper limit enhancement of Psychic Points brought by his Epic title, the consumption required to maintain his skills was almost negligible.
But it was only "almost."
The Psychic Points were still slowly decreasing.
The continuous consumption of skills exceeded the natural recovery rate of Psychic Points; as long as he maintained these two abilities, Yi Lin's Psychic Points were inevitably being used up.
