Upon hearing this number, Gray, Bone Horse, and Black Cat were all stunned. Vivian and Catherine remained calm.
"Exactly, I'm not particularly sure. After all, new saint spirits might evolve at any time, and the news from Keltos isn't reliable. There are probably over two thousand angels in the Angel Army.

"Saint spirits don't decrease?" Gray asked.
