The concept of Heavenly and Earthly Energy was quite vague, and Ye Fan's understanding of it was limited to hearsay and the Breathing Technique Manual given by Divine Doctor Wang. The descriptions of Inner Qi and Qigong were similar, involving the sensation of Qi's existence, expelling impure air, and absorbing Vital Energy to cultivate one's own True Qi. As for the sensation of Qi's existence, Ye Fan indeed had a feeling, but it was very faint.
Now, as his strength increased, Ye Fan's perception became very clear, which made him feel quite surprised. Could it be due to the work of the Clairvoyant Eye? Or was it because of the increase in strength?
Ye Fan hadn't encountered many martial artists, and the strongest he knew were likely Divine Doctor Wang and the Chief Steward, who were not around. So, he turned to Jiang Yue and said, "I feel the Heavenly and Earthly Energy here is much denser than in other places. What do you think?"
