After making his decision, Pei Xuanjing did not delay any further.
He contacted siblings Xue Hanyi and brought them with him outside the border to the army camp.
According to Tao Rong, during the years Xue Hanyi and his sibling secluded themselves, they lived peacefully without causing any trouble. It was even Xue Hanyi who actively proposed the speculation that the wolf pack the army encountered may be from the Demon Race.
Pei Xuanjing had interacted with the two before his seclusion. Apart from their initial condescending attitude, Xue Hanyi hadn't really done anything bad. Of course, there could also be the fact that they were deterred by Pei Xuanjing's strength.
Anyway, based on Pei Xuanjing's observation over these years, at least they had the sense of current affairs. They weren't the straight-laced kind who wouldn't cooperate or adapt. This led Pei Xuanjing to decide to not take action against them for the time being.
