The Black Ball was a byproduct generated when Feng Xue failed to create a Phantom Transformation using his Golden Finger. It was a special substance that could only be sustained in the environment of Infinite City. Although it had the characteristic of evaporating in the real world like a Pseudo Artifact, it couldn't maintain its existence in reality through observation and cognition like a Pseudo Artifact.
The reason for this lay in the fact that Infinite City itself was an environment rich in free-floating Identity.
This was also why surviving in Infinite City required only a ten-thousandth of the Identity needed in the real world.
To make an analogy, it's like the solute will not dissolve in a supersaturated solution.
Yet at this moment, these Black Balls were not evaporating directly as they would under normal circumstances. Instead, they were spreading out gradually, like greasy fried chicken falling on oil-absorbing paper.
