The next day, Chu Mu didn't hurry to leave the Nightmare Demon City. As a tenth level city, it could be considered the most prosperous city. Here, there were many things that Chu Mu needed.
During his three years on Prison Island, Chu Mu had gathered many valuable items. Selling all of these to buy Soul Crystals could greatly enhance the strength of his Soul Pets.
However, Soul Crystals couldn't be used continuously for training. After all, Soul Pets had a certain saturation point. If they absorbed too much Soul Crystal energy in a short time, they wouldn't be able to convert it into efficient power. This would not only harm the Soul Pet's body but also waste the extremely valuable Soul Crystals.
Chu Mu's Mo Ye had already reached the Fifth Rank Ninth Stage. To breakthrough to the Sixth Stage relying solely on battle would probably take a long time.
