Qi Xiaojin naturally had ways to track down the Sheepskin Demon's location to pursue and kill it.
But the Sheepskin Demon didn't.
It... evolved!
Or rather, the Sheepskin Demon started adapting to the modern human world and had begun learning to achieve its goals using modern human methods.
Initially, it likely threatened the life of a driver's family, forcing him to kill his loved ones.
That way, the Sheepskin Demon would leave no trace, with no clue for anyone to investigate.
One could only investigate through human means, tracing back to the origin.
By the time anyone got this far, the Sheepskin Demon would have already escaped.
Evidently, the Sheepskin Demon wasn't skilled at this operation yet, hence it left some flaws.
That driver's daughter must have been the second human skin for the Sheepskin Demon.
It figured it out!
If it kept using this method, even for myself, it would be quite troublesome.
A fierce light flashed in Qi Xiaojin's eyes.
Ding-dong.
