Although both of these ocular techniques were genjutsu, with neither being a ninjutsu for direct attack or defense, Nawaki was extremely satisfied with them.
Nawaki had never lacked means of attack or defense; genjutsu had always been his greatest weakness. To be honest, before awakening the Mangekyo, he had been even more wary of the two juniors, Itachi and Shisui, than Black Zetsu, Madara, and Obito.

He had even considered preventing Hikari and Fugaku from having children. Fortunately, after awakening the Mangekyo, he had obtained Pure Land, a heaven-defying ocular technique immune to all genjutsu. That allowed him to rest easy and let Uchiha's two geniuses be born. Shisui had now successfully graduated from the Ninja Academy, while Itachi was still a three-year-old child. Nawaki had already decided to take both of them as his disciples, partly to prevent them from reenacting the tragedies of the original story.

If it had been anyone else, being unable to act for ten whole days would have made them an easy target for sabotage.
Moreover, while Pure Land
