Looking at Luo Feng's calm face, wave after wave of shock surged in Li Yun's heart.
A martial arts technique that allows a Sixth Level God Bravery Realm martial artist to release Gang Qi is definitely not simple; it must at least be a top-tier Yellow-level martial arts technique! It might even be a Profound-level martial arts technique! In the entire Cyan Leaf School, not a single Profound-level martial arts technique could be found. There was only one top-tier Yellow-level martial arts technique, which was cherished by the dean of the school like a treasure.
Shocked for a moment, Li Yun gradually composed herself.
To have reached the mid-stage of the Sixth Level God Bravery Realm at the age of fifteen—such talent undoubtedly made him a genius! This kind of genius would definitely be fully cultivated by the academy, so possessing a martial arts technique of that level wasn't so unbelievable.
