This was because he did not want to try it rashly before he understood the profoundness of it. After all, this world was a world where the strong preyed on the weak. No one could guarantee that there would be more secrets hidden in their bodies. If he was not careful, he would be devoured.
Ye Feng had experienced this situation before, so he was very afraid!
However, Ye Feng knew that he had to constantly challenge his limits in order to become stronger and have a chance to break through to the final realm of the heavenly sequence.
And this time, Ye Feng's battle on Earth made him understand a principle -- to become stronger, he had to keep fighting. The more ways he fought, the more he could stimulate his potential, and his potential was endless.
