Don't be fooled by the fact that Xiao Xiao's Nine Phoenix Flute martial soul only has seven rings, but among these seven soul rings, aside from the first one which was a Yellow Hundred Year Soul Ring added initially to assist Huo Yuhao and Wang Dong'er, the remaining six are all Ten Thousand Year Soul Rings. Such soul rings made her martial soul's might not inferior to an eight rings Soul Douluo level expert.
The reason she didn't use the Three Lives Soul Suppression Cauldron but employed the Nine Phoenix Flute from the start was because everyone was unfamiliar with it, and the Nine Phoenix Flute possessed formidable control power.
Huo Yuhao's spirit eyes were not purely control-class martial souls, but Xiao Xiao's Nine Phoenix Flute was.
Initially, Elder Xuan told her that to become a true powerhouse, the simplest way was to achieve the extreme in a certain aspect. No matter what it was, as long as one could reach the extreme, the power would be tremendous!
