"Master, I suspect that the flow of time within the Mortal Island space may differ from the outside world. While it seemed like one hundred days to us, a much longer time may have passed in the outside world," Lao Hu speculated.
"Even so, I only spent one hundred days inside the Mortal Island, and my primordial soul wasn't outside either; it also experienced just one hundred days."
"Perhaps your soul disk's rate of advancement is calculated according to absolute cosmic time and is unaffected by any local flow of time."
