The flames in Feng Xiyun's hand were indeed not the Heaven Burning Flames, but they were bona fide heaven-grade flames.
Furthermore, if these flames were cultivated and nurtured, they would be able to reach the level of the true Heaven Burning Flames.
After seeing Feng Xiyun's charming appearance, Li Hong swooned. He swept his lecherous gaze up and down, before saying, "This girl is really beautiful. However, she is not my woman. What a pity…"
As soon as he finished speaking, the black saber in his hand flashed as he attacked, trying to catch her off guard.
Feng Xiyun's expression remained calm as she stretched out her hand and slapped the back of the black saber, easily diverting it.
Then, she hurled the ball of flames in her hand at him, when released terrifying waves of energy, forcing him to dodge and step back.
