Instantly killing three Demon Kings and gaining some experience points, for Jiang Liu, was better than nothing.
After effortlessly eliminating the three Demon Kings and looking at the three foxes in their original form, Jiang Liu initially wanted to destroy the corpses to cover up the evidence.
However, after thinking it over, he decided not to, and just let the three bodies lie there.
Nothing happened that night. By the next day, the unconscious prison guards gradually woke up.
