I'm at Hogwarts, what the heck is this Primordial System?

In the wizarding world, Rhine's magical powers only surged at nearly eleven years old, barely receiving his Hogwarts acceptance letter. He was ready to give up, until...
[Congratulations, host, on joining the Chan Sect! The Primordial Network System is now officially bound to you.]
Rhine: "This is Harry Potter for crying out loud! System, are you out of your mind?"
Main Quest: Build connections, participate in the Investiture of the Gods, and survive.
Rhine: "I'll say it again, this is Harry Potter for crying out loud! How am I supposed to participate in this battle for godhood?"
Before you stands Yuan Hong, the leader of the Seven Monsters of Meishan, a naturally extraordinary being, over eight feet tall, wielding a Water and Fire Cudgel.
Befriending Yuan Hong grants the talent of "Invulnerability to Swords and Spears, Immunity to Fire and Water, and an extended lifespan of a hundred years."
Rhine stared at the half-giant Hagrid before him and fell silent.
"Alright, so this is the primordial wilderness, right?"
"I just want to ask, are you sure this copper-skinned, iron-boned thing is genuine?"
