Le Yu himself had also discovered that the identity of "Yin Yinyin" had far too many flaws.
A white-haired assassin capable of infiltrating high society alone to gather intelligence was abnormal to begin with. There was a reason Yin Yinyin had chosen to hide in the slums and coordinate communications: because of his hair color, the chances of him being exposed were far too high, and no one could possibly believe in a short-lived white-haired assassin.
White Night's arrangement had been quite sensible. Having Yin Yinyin handle logistics, assassinations, and support had indeed allowed him to display all his talents, and he had performed excellently.
Although everyone acknowledged Yin Yinyin's ability to gather intelligence, they did not think he was doing the work of an "outfield intelligence operative," such as a socialite, a spy, or a shopkeeper. In jobs that required showing one's face, Yin Yinyin would have to shave his head completely. Otherwise, the moment he appeared, everyone would mark him as a "wild Sword Hider (low light)"—the kind that dropped equipment and gold when killed.
Don't assume Profound Candle Prefecture would be friendly toward Sword Hiders. Don't forget why Le Yu had been kidnapped. The white-haired fetishists among the merchants had even wanted to violate an assassin.

So which organization had Yin Yinyin infiltrated?
The answer was almost self-evident. The intelligence Yin Yinyin had provided included the Shi family's factory
