Reached Level 999 in Naruto: Thousand Years of Killing

Traveling to the world of Naruto, the system Gong Yubai awakened turned out to be a Millennium Killing 999 level system! The stronger the enemy you defeat, the higher the experience value you gain, and the stronger your Millennium Killing level and attributes are! Metkai: "My Eight Gate Dunjia can be destroyed with a snap of a finger under his thousand-year killing spree." Kakashi: "This is a recipe I'm familiar with, but it's not a flavor I'm familiar with." Sarutobi Hiruzen: "The Millennium Killer is the strongest ninjutsu in Konoha!" Tsunade: "This man's ninjutsu can actually make me wander in a sea of pain and pleasure!" Orochimaru: "I really want to cut off his fingers and study them!" Kabuto: "Who can tell me why he stabbed my dirty earth reincarnation back into the coffin with one finger?" Uchiha Madara: "I, Uchiha Madara, would like to call you the strongest after a thousand years of killing!" Kaguya was poked by a finger: "???"
