There were quite a few Foundation Establishment Cultivators in the Spirit Control Sect, but Chen Xiao personally came over mainly because Shen Long had attracted Tricolor Divine Thunder.
"Sect Leader, Master, why did I attract Tricolor Divine Thunder? I have consulted our sect's historical records of ancestors' insights into advancing to the Core Formation Stage, and such occurrences are rare!"
Shen Long said, puzzled.
Before attempting Core Formation, he had consulted a great number of records on Foundation Establishment Cultivators advancing to the Core Formation Stage and knew that the strength of Heavenly Tribulation varied among different cultivators. Most Foundation Establishment Cultivators faced ordinary power of thunder and lightning when advancing, a few encountered Dual-Color Divine Thunder, and it was extremely rare for someone to attract Tricolor Divine Thunder while advancing to the Core Formation Stage.
