Bai Yishan asked Han Sen to practice Yin Yang Blast often, and told him how to cooperate in the Saint Hall when they came to collect Yin Yang Blast.
Han Sen nodded and went directly to the teleport station after Bai Yishan had left. The creature he was feeding had evolved into a sacred-blood creature.
He was feeding a color shifter this time. It was a primitive creature like a chameleon. The reason he had chosen a color shifter was its beast soul.
Its beast soul was a shapeshifting one. After using the beast soul, one would not only be able to gain better fitness, but could also get protective coloration.
If one stood in the same spot for a while, then the protective coloration would allow one to be integrated into the surroundings, as if one was invisible.
However, when using the beast soul of a primitive color shifter, the color shifting was slow and not really that effective.
