The Wu'an Army and the sects within the Nine Nether Domain have been crossing swords for over two hundred years, both sides frequently planting spies in each other's ranks.
For instance, in the past within the Ciyun World, the Venerable Tian Jue had sacrificed an undercover operative at the Third-Rank of the Divine Passage Realm, paying with his life to assassinate Shen Zhui.
If the Sect Alliance could resort to such methods, so could the Wu'an Army.
Previously, Shen Zhui's status was insufficient to access such confidential matters, but now he was capable of perusing most of the archives.
There were spies stealthily gathering information within the Sect Alliance and assassins set on eliminating significant figures in the sect realm.
However, the fewer people aware of a cover operation, the better. The longer the infiltration, the greater its importance and confidentiality!
