After reaching the Fourth Order, Ye Feng gradually felt as if there were invisible shackles on him in this world.
With the World Tree's ability to control heaven and earth, he could perceive the essence of this world more clearly and deduced that, at present, one could at most cultivate to the peak realm of Fourth Order.
If he wanted to continue advancing, there probably were only two methods: one was to leave this world, and the other was to wait for the further resurgence of spiritual energy.
At the moment, the concentration of spiritual energy was still increasing.
Ye Feng could feel that as the concentration of spiritual energy increased, the shackles on him weakened bit by bit.
"If I'm not mistaken, once this resurgence of spiritual energy ends, this world's limit should be able to reach the early stage of the Fifth Order," Ye Feng estimated.
