The powerful aura surging from John's body was undoubtedly the Supreme Battle Art. While it was slightly different than the aura Mark emanated, there was no mistaking it.
Mark's cold eyes stared straight at John, and his previously playful attitude was no more.
"How did you get your hands on our battle art?" Mark asked in a cold tone.
Outsiders were not permitted to cultivate this battle art, and doing so was a grave offense in the eyes of the Supreme Battle Sect.
"My father obtained it for me," John replied back. It was the truth, as his father had gotten it for him, however, he didn't know exactly how his father had managed to obtain such a secretive and powerful battle art.
"Then how did he obtain it?" Mark asked once more.
John frowned at these constant questions, and also did not like the cold tone coming from Mark.
"I don't know, and I really don't care either. If you have a problem with me using this technique, then just come at me with all your power," John replied.
