I Survived in Anbu to Become Super Kage

Root training continued day after day. Yako kept up his facade, acting as a Jonin instructor while silently gathering intel.

Root selected another four-year-old child from the Orphanage to fill the vacancy left by Kato Shizune.

Seven days later, Danzo mastered the Tongue Eradication Seal and branded all twenty children with it.

Curse seals resembling two Yin flames and four Yang flames appeared on their tongues.

Yako thought, 'Danzo, you'd never guess that I have a piece of the Uzumaki Clan on my side.'

'You think the Tongue Eradication Seal is your ultimate trump card, but sooner or later, my little mistress Uzumaki Yuka will crack it.'

'When it comes to Sealing Jutsu, the Uzumaki Clan is the real deal—the master key. You, Danzo, are just a cheap knockoff holding a copy.'

The structure of the Tongue Eradication Seal—Mountain below, Heaven above—mirrored the Retreat hexagram from the I Ching's sixty-four hexagrams.

Among the Uzumaki Clan's sealing arts, the Four Symbols Seal, the Eight Trigrams Seal, and the Tongue Eradication Seal all seemed connected to concepts from his past life: the Two Polarities, the Four Symbols, the Eight Trigrams, and the Sixty-Four Hexagrams.
