Besides,
Su Yu also discovered several jade slips.
One of them contained a demonic technique called Blood Refinement Nine Changes Immortal Sutra.
After Su Yu used his divine sense to understand this demonic technique, he destroyed it immediately.
He simply could not abide by such a thing.
To rely on absorbing the blood essence of other creatures to refine one's own power, requiring endless killing, and yet it's named an Immortal Scripture, was very harmful.
Having cleaned out Luo Bang's Qiankun Bag and destroyed all the demonic objects, Su Yu kept some small things like poisons and anesthetics, which in his opinion, were effective even against the ninth level Foundation Establishment cultivators prepared by Blood Daoist Luo Bang.
These were good items, he must keep them.
Recalling his own formation flags, Su Yu stopped for a moment and sighed: "Taoist Friend Chen, I have avenged you."
"Since I ground him to dust, there's no need to dance on his grave to relieve my hatred."
