The reason Xu Mu chose to use a skill, rather than unleash a weapon for attack, was not that he didn't have an attack weapon; instead, he simply didn't need one.
He possessed the Void Pearl, granting him spiritual power tens of times that of other cultivators at the same level. All his skills and Divine Skills had reached the Transcendent level, with an attack power incomparably stronger than any weapon of the same level.
With both of these, he could easily crush other cultivators of the same level. Unless faced with powerful weapons such as the Sky-splitting Halberd or God Refining Tripod, there was no need for him to use a weapon.
Boom boom boom!
The sword of Fire-controlling Skill unleashed by Xu Mu exploded the moment it neared the Seventh Princess. A massive continuous explosion ensued, with the scorching shockwave swamping everything within hundreds of meters, including the Seventh Princess herself. The entire void trembled.
