To achieve Round Light, one must pass the Reappear Calamity. Apparently, "Round Light" is at the "Mysterious Level Grade C" tier.
As for "Pure Land," it mentions the "Four Strengths" and the "Four Beasts."
The cultivation technique's reference to the "Four Strengths" and "Four Beasts" with "Four" pertains to the body, soul, dream, and domain...
First, make oneself "Body Strong," "Soul Strong," "Dream Strong," and "Domain Strong."
Then proceed to hone in the "Four Beast Lands."
The Four Beasts refer to "Evil Body," "Evil Soul," "Evil Dream," and "Evil Domain."
Achieving the "Four Strengths" is like a sword blade emerging from the furnace, while the "Four Beasts" are akin to tempering it with icy water...
The "Four Beasts" correspond to "Multiple Ghosts."
The accumulation of Multiple Ghosts creates more complex changes in the Ghost Domain.
This step clearly pointed Song Cheng to his next cultivation method.
