Given the capabilities of the Blood Refinement Fiend Emperor and the nature of the Blood Refinement Fiend Sutra, it was only logical for him to control those Emperors.
Some of the Emperors here were once Patriarchs whose lifespans were almost up. If they could not break through, they could only die after expending their lifespans!
At that point of time, a Blood Refinement Fiend Sutra dangled before them. It was a cultivation technique that could increase their lifespans and allow them to break through their cultivation realms—who could resist such temptation?
Even someone as strong as Monk Daming chose to compromise and cultivate the fiend technique to break out of the ancient coffin after being trapped for 40,000 years.
However, Su Zimo still had many questions.
