"Thank you for your trouble." Qiao Mu nodded, and after she followed the Venerable Master out with her eyes, she stroked the small, pitch-black box.
Feeling the exterior, this small box was as warm as jade. Nothing at all looked abnormal about it.
However, it was only when a burst of dense killing intent, accompanied by the vital spiritual energy of heaven and earth, spurted out after opening it did Qiao Mu realize that this seemingly common box could actually completely lock up the aura of this godly blade within, preventing any of it from leaking out.
Once it was opened, a skyrocketing spiritual glow gushed out. Although this spiritual movement lasted for merely a split second, it was still enough to alarm the surrounding wilderness.
In her surprise, Qiao Mu hastily raised her head before discovering that the entire space above the room had long been sealed by a certain force. This spiritual glow couldn't flow out at all.
