Difficulty in Cultivation, the Battle Between Yin and Yang!

Ling Yun was in big trouble this time!

Ling Yun had known that the immortal spiritual energy was hidden in his energy center. However, he hadn't been able to use it since the immortal spiritual energy was not under his control. All his efforts would be for naught if it exploded from his energy center and devoured his Yin and Yang energy. He wouldn't be able to cultivate the Yin-Yang harmony balance!

"F*ck, it just had to appear when I least need it. It's obviously playing with me!" A distraught Ling Yun shouted in anger.

The reason for his depression was well-founded. He had reached a critical moment in his cultivation. He was advancing from Physique Tempering Stage Three to Four. It wasn't simply just another breakthrough.

It was an advancement from the beginner stage to the intermediate stage. He wouldn't need to be afraid of the immortal spiritual energy going berserk in his body once he broke through to Physique Tempering Stage Four.
