Agul, even when sealed by the Curse Power, was able to fight a Sacred Beast as powerful as Azure to a standstill, let alone now that Beiting Huang had contracted with him and the Seal Power had vanished, greatly boosting his strength. Just how many trump cards he still had was something that Beiting Huang had no idea whatsoever.
The process was somewhat lengthy. Throughout the taming process, Beiting Huang did not skimp on the Chaos Divine Source, using a large amount of it mixed with a bit of the Nine-Colored Nirvana Fire, passing it through their meridians once. As expected by Beiting Huang, their bloodlines were severely eroded by both the Curse Power and Evil Energy.
Azi's condition was the most serious, perhaps related to her giving birth in the Cursed Land; even her divine senses had been slightly affected. Fortunately, whether it was the Chaos Divine Source or the Nirvana Fire, both were treasures of the world and were incredibly effective in restoring their bloodlines.
