Gregorio has some understanding of anti-magic, its not inconcevable that he could also elevate his state of being like Shang has if he deigns to help him. Shang dislike mana but he still find Gregorio a worthwhile ally. He might decide to invest in him to ensure his further cooperation. If George managed to fuse Shang’s DNA with an abomination at the true path stage, I’m sure an Emperor could figure out a much more comprehensive way, especially with a working template in front of him.
