Bai Xiaowen knew exactly how powerful a so-called "Lesser Demon King"—a demon with a High King Tier Template—could be.
In a plane of low to moderate difficulty, a King-tier Template was enough to make someone the final boss of the entire world. The Black Heaven Cult's leader and Temüjin in the Shaoding Plane were examples.

Where to place the Resonant Teleportation Formation was another question.
