Uchiha Yi was confident he could temporarily boost the strength of those close to him, much as Hagoromo Otsutsuki would give Naruto and Sasuke cheats in the future. Of course, the two could receive those cheats directly because of Indra's chakra and Asura chakra within them. What Hagoromo Otsutsuki did was mostly awaken the power they already possessed.
After all, what was wrong with a father passing his power on to his sons?
As for Uchiha Mikoto, Hyuga Rinka, and Kushina Uzumaki, they were all descendants of the Sage of Six Paths. Their bloodlines were quite pure, making them standouts within their respective families.
Uchiha Mikoto's inherited talent was actually quite impressive, and her ancestors had awakened the Mangekyō Sharingan before. Both her grandfather and her parents had been quite strong. Among the younger generation of the Uchiha Clan, her bloodline potential could rank in the top five.
Now, with Uchiha Yi's guidance, Uchiha Mikoto was improving rapidly, not falling behind Nawaki in the slightest and even edging ahead of him.
Uchiha Mikoto had also awakened her Sharingan to the three-tomoe stage. Reaching that point at thirteen was already an exceptional achievement.
Had she been any younger, her body might not have been able to keep up.
Hyuga Rinka's talent was among the best in the Hyuga Clan, and she was one of those with the purest bloodlines. Not everyone in the Main Family could be useless. In fact, their bloodlines really were superior, and with the Hyuga Clan's inherited teachings, Hyuga Rinka might well reach Kage level in the future.
As for Kushina Uzumaki, she was practically a little Mito Uzumaki. Even Mito Uzumaki acknowledged that Kushina Uzumaki's talent was no less than her own. As long as Kushina Uzumaki steadily improved her strength, she had a promising future.
