Jiang Yuebai left in a hurry.
After she parted ways with Chu Liang, she led the lady to the temporary sanctuary provided by the Tang Family. Because she later learned that Chu Liang had barged into the City Warden Office and been arrested, she immediately rushed back to Shu Mountain that very night.

Now that they had ironclad evidence, what they needed to guard against was the city lord's attempts to suppress this matter with autocratic might. As long as they had the support of their Elders from the Sect, even if the city lord was immensely powerful, he could not interfere with the matters of the Nine Heavens Immortal Sect.
The Nine Heavens and Ten Lands, albeit merely a sect, were capable of sitting down and negotiating terms with the Xia Clan's Royal Family. For these imperial court officials to attempt to intimidate a cult was sheer wishful thinking.
