Although he knew 013 was a Crow God, there was more than one Crow God.
The uncertainty was still significant.
Lu Heng came up with an idea, saying, "Next time we encounter 013, we can try to discern its spiritual power to confirm if it's the same one, to determine how many Crow Gods there are. The more there are, the more troublesome it will be to deal with them."
Xie Shi'en pondered and said, "Based on my feeling, the 013 I've encountered are all the same one, there have been no fluctuations in spiritual power. It seems that a single Crow God is responsible for this and will continue to be unless this Crow God dies, otherwise they won't switch to another."
Regarding the Crow Gods, Lu Heng had only seen related documents in his past life and had never seen them with his own eyes.
If he had seen them in person, he certainly could have identified them sooner.
