Outside the courtyard.
"Family Head Xie, please come in!" a voice emerged from thin air beside Xie Zhengtian's ear.
He was immediately shaken to the core.
Sound Transmission into Secret Skill!
His heart grew even heavier.
Knowing of this technique as the Family Head of the Xie family was natural.
It was often a method that could only be mastered by someone in the realm of Fifth Grade Internal Strength.
One needed to have mastery of Inner Breath and mould spiritual power from the intangible to tangible, reaching the level of leaving the body, before one could utilize the Sound Transmission into Secret Skill.
For this reason, the Sound Transmission into Secret Skill was often something only a strong practitioner in the Fifth Grade Internal Strength Realm could grasp.
"I dare not offend!"
Xie Zhengtian sighed inwardly.
After that, he stepped into the courtyard of the avenue where Jiang Ning was located.
