If there's an internal investigation, then the thirty participants in the battle will be the focus of the scrutiny.
Once attention falls on the thirty participants, the identity of Qi Jin, whom Xu Jin has transformed into, will be noticed by the higher-ups of the Blood God Sect immediately.
There's no way around it; Xu Jin's presence as a newcomer is too recent.
Moreover, it's under the command of the current Vice Sect Hierarch.
If someone backtracks from the timeline, they'll discover that since Xu Jin arrived in Blood Moon City, the Blood God Sect has been plagued with incidents—first the special envoy was assassinated, then the Purple Wing King and the special envoy were ambushed and killed, including this event at the Limit Breaking Secret Realm.
Many things don't withstand scrutiny.
Once scrutinized, it's found that Xu Jin's connections are full of coincidences.
