Fox Spirit Matchmaker: Magical Gadgets

The truck of a transmigration godfather sent him to the world of Fox Spirit Matchmaker, where, like other protagonists, he received a System cheat. But his cheat seems a little strange. Come on, System, explain this to me: what's with Nezha's original loincloth from One Hundred Thousand Bad Jokes? And what's with this solar-powered flashlight? Never mind, I can put up with all that. But you promised me three of Sun Wukong's life-saving hairs. Why did you give me three armpit hairs instead? System: Armpit hair is still hair! (Trying to wriggle out of it.) Fine, fine! You win. I'm done with this. (Giving up completely.)
