Zhou Yi was sizing up the Ring Solar Wall that lay before him.
It was difficult to measure its precise height.
The visible area was just the circle around which the red light was congregated. Some form of force obscured the regions farther away, making it hard for Zhou Yi to distinguish between the darkness itself and the black gemstones.
Here, the White Gemstones were the least common.
They floated and moved among the other gemstones, seemingly acting as lubricants to prevent excessively strong reactions between different gemstones.
Zhou Yi also noticed a transparent liquid flowing on this wall, which would sometimes evaporate into a gaseous state and sometimes solidify locally.
It was the body fluid that would be found inside a living Heavenly Person.
If the Ring Solar Wall was ultimately proven to be another form of Heavenly People, Zhou Yi would not be surprised.
