After summoning Chen Xun using the secret technique, Yin Ji handed him a note, saying, "I received a message that there may be remnants of the Wu State here, and they seem to be at the Primordial Spirit Realm.
You must immediately summon all the spies from the thirty-six northern prefectures of Jiangnan Prefecture here, so they can verify this message."
If there truly are remnants of the Wu State at the Primordial Spirit Realm, inform Lord Gu Donglai immediately."
Although Jiang Heliu had suggested Yin Ji to mobilize the spies from all of Jiangnan Province, Yin Ji did not act upon such extreme measures.
Jiang Heliu was not part of the Six Gates and didn't know much about their inner workings.
Even if the criminal investigation secret agents were incredibly efficient, it was impossible to gather them from all around Jiangnan Prefecture in a single day.
