A Heart Demon!
After the previous gathering of the Zhou Tian Boundary Officers, Zhou Heng had sought information from the inner circle of the Five Emperors to avoid being at a loss when encountering Demon Entities.
A Heart Demon was one of them.
This type of Demon Entity was intangible and formless, wandering the spiritual world, excelling at constructing various illusions, targeting the weaknesses of the human heart, and then devouring the Divine Souls of those who were beguiled by the illusions.
Zhou Heng had attempted to use his Divine Sense to investigate Yuxiang Town, and immediately alerted the Heart Demon "Huomang" lurking there, which entangled a thread of his Divine Soul and dragged him into an illusion.
However, because Zhou Heng knew from the start that it was an attack from a Heart Demon and had learned some of its mind-bewildering techniques, he wasn't truly fooled.
