Versatile Mage: Dual-Element Summoner

It makes sense that I can't figure out why I was reborn, but why did my fair-skinned face in my previous life turn into a head as black as coal? Hey! With the protagonist right beside me, how am I supposed to dig up the Black Vatican's dirt and crush Demon Mo Fan? Reborn as a coal-black-headed Guangu. I won't drop this story, and there's no barrier to entry, so please add it to your collection.
