How did his cultivation base suddenly go from the Foundation Establishment Realm to the Core Formation Realm? Did he perhaps use an artifact similar to those two servant girls…?
Not understanding how the young master of the Hollow Thunder Family had suddenly managed to improve his cultivation base from the earlier stages of the Foundation Establishment Realm all the way up to the Core Formation Realm within the short period of a few minutes since he had entered the large estate, the only reason Xuan Hao could come up with was that the young master had used some sort of artifact to hide his cultivation base.
Even then, Xuan Hao could not help feeling that there was some other reason for the change in the young master's cultivation base. After all, the chances of the Hollow Thunder Family having an artifact that had the ability to fool someone who was in the Peak of the Domain Lord Realm should not be that high.
