Uchiha Yi felt he might now be on par with Hagoromo Otsutsuki in the past—not Hagoromo at his strongest, but Hagoromo when he fought Kaguya Ōtsutsuki.
As for how strong Hagoromo was now, Uchiha Yi had no idea. He suspected Hagoromo might be even stronger than he had been as the Ten-Tails Jinchuriki.
When Kaguya Ōtsutsuki broke free of her seal, Hagoromo had not even needed to act himself. He only had to help Sasuke Uchiha and Naruto Uzumaki awaken the Asura Chakra and Indra's Chakra within them, then give them some of his own Six Paths Yin-Yang Chakra.
Of course, Obito Uchiha had been able to lend his power to Kakashi Hatake, and it was entirely possible Hagoromo had helped from behind the scenes. Compared with Kaguya, Hagoromo seemed more like the true mastermind.
Hagoromo had shared the seeds of Chakra with the people of the Shinobi World, giving them a path to power. After they died, their souls went to the Pure Land. What kind of place was it, and was Hagoromo arranging something there? Uchiha Yi did not know. He would have to keep exploring this world to find out.
Fortunately, he had the Battle Space. Whether it was the Sage of Six Paths or Kaguya Ōtsutsuki, Uchiha Yi believed catching up to them was only a matter of time. After all, he was still just a twelve-year-old boy.
He had plenty of time left to grow!
After that, Uchiha Yi dealt with masked Obito just as easily. Kamui was troublesome, but Uchiha Yi was cheating: he used Limbo: Border Jail to strike from the shadows.
Besides, Uchiha Yi had Yomotsu Hirasaka himself. If he wanted to, he could enter the Kamui Dimension through it at any time and kill Obito Uchiha by force.
