Chapter 138: Chapter 135: Yang Caidie Reappears_1

Demonic beasts are after all different from humans. For demonic beasts, their spiritual intelligence is limited, and they don't possess any special cultivation techniques. The enhancement of their strength simply depends on their innate longevity.

Yang Chen is confident that with his help, he can improve the strength of the two silly bears in a short period of time.

This alchemy process took a full half an hour.

Yang Chen's incredible alchemy technique left the Mermaid girl Rainbow staring in amazement.
