Spiraling

Naruto has a chakra defect, he can only access it by channeling it through objects which leads him to be a Kenjutsu master and a Seal master. He had a high IQ and decided to put himself in the TI department at the tender age of 6 thanks to his Jiji. Now he spends his time decoding messages and creating new tactics for communication between shinobi.

Shikamaru through Tsunade the Godaime met Naruto after a mission provided coded information to be decoded. What happens when these two meet?

No Tailed Beast
