The Heavenly Blade Sword Master seemed completely unaware of his own transformation, and even Tie Dan, facing him, hardly noticed at first.
After all, both of them were fully focused on the sword fighting and magic, with their attention highly concentrated. Besides keeping an eye on the opponent's deadly moves and transformations, they also had to be aware of the slightest changes in the surroundings, leaving them really blind to the moment this change occurred.
But if Tie Dan remembered correctly, until the Heavenly Blade Sword Master used the first move of the Blood Talisman Divine Sword, he still appeared normal and humanoid. However, when he subsequently used the two swords, Jia Shen Sui Lei and Jia Shen Xuan Quan, his appearance became somewhat indistinct and indescribable.
