My Multiverse System: Naruto's Apex Beginner

Ten years old, a bullied orphan in the brutal world of Naruto, Xia Muyang is destined to be cannon fodder. He's desperate for a \"golden finger.\" Ding! Myriad Realms Mission System activated! Instant mastery, system synthesis of bloodlines, forbidden jutsu, and even powerful weapons from other worlds. But with ultimate power comes an ultimate price: fulfill the quests across the multiverse, or be erased. His first task? Humiliate the Uchiha bully who just trampled his life... by making him publicly declare himself a pig. But what happens when the next challenge is a Sharingan user, and the system's \"rewards\" include skills far darker than he imagined?
