Mingye gave it some thought, then nodded, rose to his feet, and spoke to Orochimaru again.
"I need to help him deal with some document-related matters. I was the one who established that code system in the first place, and it seems I'm the only person he can trust now. All right, you two keep making a fuss here. I have work to do!"
"Big Brother, can I come with you?"
"Forget it. You'd better not get involved with that place."
Orochimaru wanted to go to the Anbu with Mingye, but Mingye was clearly displeased and tried to dissuade him. Orochimaru did not insist, and Mingye turned and headed toward one of Root's bases.
After walking through Konoha's streets for roughly thirty minutes, Mingye arrived at a corner. An Anbu ninja appeared behind him and dropped to one knee.
"My lord, may I ask what brings you here?"
Because Mingye often came here with Shimura Danzō, the Root members knew him. Rather than attacking and capturing him outright, they questioned him. Mingye handed the ninja the written authorization from the letter and explained.
"Shimura Danzō sent me."
After examining the authorization and confirming it was genuine, the Anbu ninja opened a glowing wall in the barrier. Mingye entered alone and soon arrived at a room Shimura Danzō had specially prepared for him. He did not look around too much, since he was under surveillance. In all the years he had helped Shimura Danzō, Mingye had never asked what Danzō had done, nor had he ever questioned the nature of the tasks Danzō gave him. This preserved their friendship, while the occasional subtle reminder or loyal admonition made Shimura Danzō believe Mingye was an utterly rigid and old-fashioned man.
"These documents are merely a cover."
Mingye was carefully decoding the
