章 391: The Challenge

Xu Qing's expression didn't change. After he withdrew everything, he sat cross-legged and meditated for more than an hour.

On one hand, he had to show that he was not able to form the fourth ball of life fire.

On the other hand, he could sense the transformation in his body after the fourth ball of life fire formed.

His combat strength had improved by leaps and bounds.

Other than that, Xu Qing also sensed that 120 magic apertures wasn't the limit. He vaguely felt that his body wasn't perfect and he was missing a magic aperture.

"What I lack is the 121st magic aperture that Master mentioned. It's also the last magic aperture that all four fires cultivators yearn to open."

Xu Qing mumbled inwardly.

"Only between life and death can I open the 121st magic aperture?" Xu Qing tried to sense it but to no avail. He thought of Old Master Seventh's words and fell into deep thought, but he wasn't in a hurry to open the last aperture.
