"Let's test it out!"
There was a spirit pearl on the table that was specially used for testing one's cultivation level. This saves Yao Yue the trouble of asking more questions.
The truth to one's cultivation level, that could not be seen by the naked eye, would be quickly revealed with the help of the spirit pearl.
The Innate (Stage) spirit pearl could be used to measure the cultivator's spiritual source to determine all stages of the Innate cultivation level. The spirit pearl would indicate the colours: red, orange, yellow, green, blue, indigo, purple, black, and white which respectively corresponds with the origin court, occupied void, and the start, middle and end stages of the three upper spiritual levels.
Xu Xiaoshou received the spirit pearl.
He had used this thing before in the outer yard of the Spirit Palace, but at that time, he was using the Acquired (Stage) spirit pearl.
