Unrivaled Sword Art

"You weren't certain I was the real deal? What if I had been an imposter?" Tian Qiyuan asked her out of curiosity.

Hearing this question, Zi Xuan's expression darkened, looking incredibly grim, and she responded in a chilling voice, "If you had dared to impersonate the Exalted Blacksmith, then I would've tortured you until the end of time."

Her gaze exuded real killing intent that sent shivers down Tian Qiyuan's body. 

"Alright, then, let's take a look at your swordsmanship now," he said a moment later.

Zi Xuan nodded her head and said, "Let's go outside."

Before leaving the vault, Zi Xuan took the Spirit-grade sword with her.

Once they were outside, Zi Xuan brought him to the empty field behind the building.

"I will now perform my main sword technique, Unrivaled Sword Arts. It consists of nine stages, each several times stronger than the last."
