"What exactly is this 'Superior Miracle' thing, above and below?"
Within Avalon Castle, Bailuo called his uncle to specifically inquire about this miracle.
"It's a very powerful miracle. I've seen it mentioned in the books left by the Ancestor of Yadun," he said.
Afterward, his uncle carefully explained to Bailuo just how formidable this miracle was.
In addition, Empress Cain mentioned the true names of many other Masters of Miracles, and Bailuo inquired about each one.
It must be said, Bailuo did not lose out in this exchange.
The mutual sharing of information on upper-tier miracles provided Bailuo and Empress Cain with the opportunity to establish an initial trust. After that, all it would take is for Hailbo to be sent on a diplomatic mission to draw Holy Blood Nation into Bailuo's alliance.
Moreover, Empress Cain, on the surface, was not inferior to King of Aolai. If she truly revealed the power of the Superior Miracle World, she would likely be stronger than King of Aolai.
