Any veteran cultivator above the Innate level could easily enter into a meditative state through cultivation under normal circumstances.
However, when it comes to traversing the Great Void, it is universally acknowledged that few can achieve it.
Typically, it's only possible to achieve such a state of communion between heaven and man and enter it relatively easily after reaching the Heavenly level.
To advance to this state once is considered a significant breakthrough, serving as a golden opportunity that is to be found rather than sought.
Despite Zhuang Weiran being a Heavenly level cultivator, since his ascent to this height, he has only managed to enter this state of traversing the Great Void thrice by now.
Each time upon awakening from this state, his strength would take a leap forward.
The enemies he previously could not defeat, the opponents on par with him, would be left in his wake.
