While exploring this new world, he also tried to kill some weaker demon beasts.
After killing them, Su Yang found a milky white bead in their bodies.
When he received this milky white pearl, his interface immediately sent him a message. This milky white pearl could be absorbed by the internal universe and could also be converted into the golden will of all living beings.
Su Yang immediately began to study the bead. Soon, he understood the essence of the bead, or rather, he also studied the essence of the dark crystal.
To put it simply, this bead was a high-level source. The more powerful the demon beast, the higher the level of the source crystal contained in its body.
