After Su Ping arrived at the Demigod Burial, he merely waited at the random landing spot for a short while before a god was sent over by Joanna's true self, to escort them to her residence.
As soon as they arrived, Joanna summoned her trusted follower and inquired about Heaven's Test.
The answer was to Su Ping's relief.
It had not started yet.
But that middle-aged god had sensed the summoning and could initiate it at any time.
He was waiting for them to arrive.
That was Joanna's order before she left!
There was something else, another pleasant surprise. During the time that they were away, another two at the peak of the titled rank had sensed that their Heavenly Tribulations were approaching and wanted to go there to pass the test.
