Zhou Tian's idea is correct from any aspect. If he can actually gather a group powerful enough to pose a deadly threat to the headless knight, a Saint-level Undead, then there wouldn't be any issues with breaking the confines of the Undead Domain.
However, Zhou Tian, although willing to find help, didn't anticipate that he would have failed to find the sought-after Saint-level Monsters, but instead stumbled upon Hellfire.
Hellfire could also be considered a member of the Saint-level Monsters, and in fact, Hellfire's combat power is above most Saint-level Monsters. Supposedly, if there is no accident, even with Hellfire's combat power alone, Zhou Tian could be a substantial threat to a target like the Headless Knight.
However, while Zhou Tian highly acknowledges the strength of Hellfire, he also has to admit that Hellfire has a very troublesome character.
