If you want to suppress this Heart Demon King, once it triggers a counterattack from the Heart Demon King, even for the ancient emperors, being drawn into a heart demon is an extremely troublesome matter.
Suppressing the Heart Demon King is definitely a mutually damaging affair.
Moreover, this Heart Demon King has only affected Xin Hen Peak.
This is why it has been delayed all along.
However, for Chu Fengmian, something that is immensely troublesome to others is actually a good thing.
Chu Fengmian had once heard that the Heart Demon True Emperor, when he first stepped into the Emperor's realm, was just a small figure with some minor fame.
It's indeed rare for an emperor to ascend by the heart demon, but later the Heart Demon True Emperor became famous for facing off with an ancient emperor shortly after becoming a First Tribulation True Emperor.
