Perhaps he no longer counted as Uchiha Yi. Perhaps he was Ōtsutsuki Yi now.
And he was only ten. If he were a few years older, he might truly be invincible in the Shinobi World as it stood.
A Complete Body Susanoo was already formidable. Before, Uchiha Yi's young body had struggled to keep up with his Sharingan, holding back its development. But after merging with Asura's physique, he discovered for the first time that his eyes could not keep up with his body. After all, the physique he had gained belonged to Asura at fifteen or sixteen, while he still had to develop his Sharingan himself.
He could develop that physique further, too. By merging with Asura's physique, Uchiha Yi had also gained its future potential.
Another thought soon occurred to him. If he put in the effort, he might even be able to develop Wood Release.
If he, an Uchiha, used the First's Wood Release, who knew how the Senju Clan—or even all of Konoha—would react?
Mito Uzumaki would probably be bewildered when she saw him.
She might even see a trace of Hashirama Senju in him.
Still, even though he could summon a Complete Body Susanoo, his eyes remained Three-Tomoe Sharingan. Uchiha Yi could not help wondering whether he would ever awaken the Mangekyō Sharingan. That hardly seemed fair.
He knew the Mangekyō Sharingan was a special stage that had emerged after the bloodline declined, but he still coveted its unique Dōjutsu!
Mito Uzumaki had said Madara Uchiha's Dōjutsu could multiply the power of Ninjutsu. Sasuke's Amaterasu and Kagutsuchi might not look like much, but they were formidable in practice. Even Kaguya Ōtsutsuki was wary of Amaterasu.
There was Obito Uchiha's Kamui, Shisui's Kotoamatsukami—hailed as the strongest Genjutsu—and Uchiha Hikari's almost absurdly powerful Yachihoko. All were Dōjutsu
