"The Blood Refinement Fiend Sutra again!"
Su Zimo's heart skipped a beat and he narrowed his eyes.
Up till now, he knew that there were close to ten people who cultivated this fiend technique!
He was already shocked that Patriarchs on the Divine Power Ranking cultivated the Blood Refinement Fiend Sutra. To think that even an Emperor cultivated this fiend technique!
Su Zimo had no desire to chase after Di Yu after the latter released Dharmic Blood Escape.
He knew the Blood Escape technique the best.
Unless he was an Emperor, there was no way he could catch up to Di Yu!
At the same time, Su Zimo understood something.
There was a high chance that Di Yu had cultivated the Blood Refinement Fiend Sutra 10,000 years ago.
Back when he descended to the North Region and ambushed the red-headed ghost, he even wanted to kill the latter. It was not because he wanted to save the cultivators of Daming and Fahua Monasteries.
