Compared to the initially tense encounter with the Evil God, Zhang Yu's interactions with Fu Ji had become increasingly calm, and he was gradually getting used to having such an entity close at hand.
Of course, this was partly due to Fu Ji constantly showing vulnerability and aiming to invest in Zhang Yu, demonstrating her value repeatedly.
At this moment, after setting aside the Great Sun Qi Sea for the time being, Zhang Yu asked Fu Ji, "What would you recommend in terms of mental methods?"
Fu Ji was well-prepared for this.
Having observed Zhang Yu closely for so long, she had long contemplated his strengths and suitable future paths for development...
Fu Ji said, "You've practiced the Wild Bull Soul Suppressing Heart Technique before, right?"
"There's an upgraded version of that heart technique, an Expert Level Skill, suitable for practice at the Qi Refining Middle Stage, called the Can Niu Soul Heart Technique."
