In the past, the people of the sea exploration sect did not have the conditions to cultivate The Fiend sect's cultivation techniques. But now, they did not have to worry about anything. With the blood Lake and soul beads, they did not have to worry about cultivating The Fiend sect's cultivation techniques.
Every year, the sea exploration sect had to kill a lot of demonic beasts to eat their meat. These demonic beasts did not have spiritual intelligence, so they did not have any psychological burden. Then, they would collect the beast blood and beast souls. The beast blood would be poured into the blood Lake, the beast souls would be sealed, and put into the soul ball. This way, the two most important materials for fiendish cultivators 'cultivation would be complete.
