Luo Wushuang was shocked. This blade from Qin Mu was extremely sharp. It stabbed through his first heaven without alerting Luo Wushuang of its power.
He was young when he entered the path with the knife. The first move he learned was Opening the Green Sea Clouds. When it was unleashed, it was as if a green sea was shrouded by clouds. When the clouds opened, the knife skill would change as torrenting waves descend from the heavens.
This move was the first move he learned when he entered the path. At that time, he had accumulated little and wasn't so exquisite. Thus, it was normal that it was broken.
Yet, in the next moment and in the next blade, Qin Mu broke his knife path's second heaven, Jade Lock Urgent Snow. This way of entering the path required the use of divine arts. The knife light morphed into flying snow that bombarded the enemy while the mysterious ice formed a jade lock that locked the cold in.
