One must understand, Jing Yan already possesses profound comprehension of the Space-Time path; the highest level Space-time Laws existing in the Heavenly Domain are almost incapable of perplexing him.
Of course Jing Yan does not dare claim that he has mastered all Space-Time Dao Techniques, but even for those he has yet to fully comprehend, he is certainly not unfamiliar.
Yet what exists upon this Beast Skin letter is something that even makes Jing Yan feel a sense of unfamiliarity.
Merely this faint Dao Rhythm Law is enough to move Jing Yan.
The content of the letter is very simple, only one sentence: Tianbei Sect's Lan Zan invites City Lord Jing Yan to come to the Sect for a talk.
This name Lan Zan, Jing Yan is quite familiar with; this person is precisely the Great Sect Master of Tianbei Sect. Tianbei Sect can be counted as the most low-profile Superpower in Kunling Heaven, and Grandmaster Lan Zan is exactly the leader of this most low-profile Superpower.
