It could be said that everything Supreme Evil Daoist had done had ultimately been making a wedding dress for him.
Added to the materials he had plundered from the Black Demon Clan, the two sides together made up nearly everything he needed.
Now, only one material called Blood Transformation Grass was missing.
Yang Chen had heard a little about this Blood Transformation Grass. It was an extremely sinister spirit herb. If someone whose cultivation was insufficient touched it, it would immediately suck that person's blood dry. Even experts at the Spirit Disk Stage, Golden Venerate Stage, or Demigod Stage could die on the spot.
Only those who had reached the True God Stage, with sufficiently formidable divine power, could pick this herb.
The Blood Transformation Grass contained astonishingly potent blood essence, making it perfectly suited as a medicinal catalyst for pill refinement.
Speaking of which, Yang Chen had to admit that the materials needed to refine the Nine Nether Immortal Pill were all wicked objects. Even if they were not as sinister as the Blood Transformation Grass, they were not far behind.
No wonder Supreme Evil Daoist had gathered so many of them. As an evil cultivator, plundering such utterly wicked materials could not have been easier for him.
Yet the Blood Transformation Grass was clearly hard to find. Yang Chen had only heard of it because of how rare it was.
He had originally been eager to begin refining the pill, but now he could only temporarily suppress that thought...
"I wonder when I'll be able to find Blood Transformation Grass. Still, there is no need to rush the refinement of the Nine Nether Immortal Pill..." Yang Chen murmured to himself.
After Yekun left, Yang Chen also chose to enter seclusion at the Northern Territory Sect for a time.
