Yan Yu felt increasingly unwell.
Firstly, he occasionally felt somewhat fatigued.
A Golden Core Cultivator's body is in a state of perfect balance, generally should be energetic at all times, and fatigue is a typical symptom of energy depletion.
Secondly, his stamina was also shortening.
Yan Yu had to start considering a question: was he really under a curse?
Although Anna firmly denied it, Yan Yu was more unwilling to believe that his perfectly honed body would start declining due to too much fighting—it must be this treacherous blond secretly cursing me!
The demons of the Northern Border were not hard to deal with. First, the number of blood sacrifices was severely insufficient, making the average strength of the demons extremely weak; second, both Yan Yu and Anna were in the Golden Core Realm, so eliminating them wasn't very difficult.
