As Lann and Black Conical Hat Li stepped out of Hirata Manor, the situation regarding Immortal Peak Temple had already started spreading among the populace.
The matter of Yamai Diansan's broken leg could not be concealed at all. As the Iwami General responsible for the manor's defense, he couldn't remain unseen for long periods.
As a leader, his health was not only his private affair but also a public matter for which he must be accountable to his subordinates and superiors.
An injury must have a reason, and under the deliberate care of Iwami Yixin, Yuzi Jiu Lang, and others, the news that "Immortal Peak Temple has fallen into heresy and become a Demon Cave" spread like wildfire.
This was the reason why Lann made a special trip back to the Hirate family.
After learning from Black Conical Hat Li about the collaboration between Immortal Peak Temple and Iwami, he knew it was impossible to borrow people from Iwami to purge Immortal Peak Temple.
