Jin looked at him and spoke,
"Did you not find something great as you look at the symbols on the stone?
The north direction shows the dragon thunder, meaning the energy that this plane masters can belong to and the south showed the energy of yin attribute. The right side showed the yang attribute and the left side showed the darkness.
It means these four pillars that might be related to the experts of this plane and this might be the requirement to activate the key."
Hearing this everyone paused and looked at the stone carefully.
All the four positions of keys are represented by a colour. The top one has a slightly blue colour.
The most below is somewhat white in colour. The left side is pure orange and yellow and the right side is pure black. Everyone also feels that this speculation is correct.
