General Jiao Long took Byung's current form as his way of protecting his friends despite knowing quite well that should Byung assume this form in front of his friends, they would be killed.
Jiao-Long wanted to test out the current strength of Byung in this partially manifested state, despite it just being a fragment he was on par with Jiao-Long.
Jiao-Long now understood why Xing sent him specifically and that was because Byung would kill anyone else if they met him in this form.
Jiao-Long heard news about his ability to control the key's influence but that ability seemed lacking right now.
Byung was not in control but Jiao-Long did not care as he planned on beating sense into Byung.
The battle waged on and it was in the favour of Jiao-Long because Byung could not even conr close to him without feeling the brute of the flames emitting from his body.
"Thats right kid! You can't touch me,' The Geberwl said proudly, but it was not Byuhg he was fighting.
