It can be said that the Supreme Evil Daoist did so much, completely making a wedding dress for Yang Chen.
In addition to the materials he had collected from the Black Demon Clan, the two sides combined made it just about enough.
Now, the only thing missing was a material called Blood-transforming Grass.
Yang Chen had heard of this Blood-transforming Grass, which could be said to be a very sinister Lingcao. If a cultivator with insufficient cultivation touches it, it would immediately suck the blood of the person who touched it. Even powerful ones in the Spirit Plate Stage, Jinzun Stage, or Demigod Stage could die on the spot.
Only when one reaches the True God Realm and has enough divine power can one pick this flower.
Inside this Blood-transforming Grass, there is an incredibly astonishing amount of Essence Blood, so using it as a medicinal guide for alchemy is simply more than appropriate.
