Bang!
The moment fists and palms collided, Zhao Xingxuan's body trembled. He felt the terrifying force contained in Gu Chen's punch. If he hadn't reached the Gang Qi Realm's peak, with an immense and solid internal energy, he would have suffered severe internal injuries from this blow.
"Good boy!"
Zhao Xingxuan let out a deep shout and no longer held back. He gathered Gangqi within his body and used the superior martial skill of the Red Flame Demon Sect, slapping his palm towards Gu Chen.
"Purple Sun Hand!"
Feeling the overwhelming force of Zhao Xingxuan's palm, Gu Chen's heart fluttered with a sense of trepidation. He knew that facing a warrior like Zhao Xingxuan, who had perfected the Gang Qi Realm, he could not afford to hold back at all and had to go all out.
