Army of Heaven leaves
Evidently, Israfel, the former Supreme Pontiff and last of the Holy Church, was considered to be the spokesman for the God of Heaven; the Biblical God of the Catholic religion.

Medes only needed to reveal that Bai Zemin had murdered the Supreme Pontiff and the entire Holy Church would immediately turn against him and the Transcendent faction.
"I must say that although what you did is something simple and basic it is still quite effective in preventing me from being able to join the forces of the Holy Church with my faction." Bai Zemin nodded and even gave a thumbs up towards Medes, "Once the Holy Church and its forces belong to me, there will be no force on Earth capable of stopping me. Not virtually, at least."
