Chu Qingyun's most powerful killing move is the Heavenly Chu Thirteen Swords.

His strongest defensive martial skill, however, is his self-created Transplanting Flowers and Trees.

Thus, Chu Qingyun held his sword horizontally in front of him and fully unleashed the Heaven Devouring Art, executing the ultimate skill Transplanting Flowers and Trees.
