1 I watched the animation a few days ago. Before U gave it to the crow, his eyes seemed to be in a kaleidoscope state, and the space at that time was very similar to the space state of the moon in Kakashi, but after giving it to the crow, After that, it is the three magatama state, so this crow must be related to the kaleidoscope.
U did not use Tsukuyomi when he fought with Sasuke. The genjutsu that required Sasuke's eyes was definitely not Tsukuyomi. Just compare Kakashi's Tsukiyomi. Kaka was nailed to the cross like Jesus, and The surrounding space is all twisted space. And Sasuke's illusion was still a shadow clone to trap him, and the surrounding environment was not that distorted environment. Moreover, Sasuke's abilities after opening his eyes are all U abilities. They have not increased, but have lost the moon. So I think Yue Yue's ability lies with Naruto.
The illusion of the moon is to make the person who is affected by it be controlled by the person who controls the space, so I guess it is U who gave Naruto his control ability of the moon world. Then the next question is how this monthly world came to be. In the recent comics, Naruto and Sasuke have fought, but this crow did not work, and Sasuke's kaleidoscope has become blind, so it can be determined that this crow is not written against Sasuke. The Rinnegan genjutsu works, and U didn't know what Sasuke's Sharingan Mangekyō looked like when he died, so this crow only works after Sasuke transplants U's Sharingan.
So U’s crow gave Naruto his own ability to control the monthly world. U and Sasuke had no use for the monthly world. It may be because U has lost the ability to control the monthly world, so there is no Use monthly. Moreover, U's attempt to kill Madara by planting Amaterasu in Sasuke's eyes failed. He must have thought that Sasuke would become blind because he frequently used kaleidoscopes for revenge under Madara's bewitchment. He would also transplant the kaleidoscope left by U, so he must have the monthly ability. When Sasuke and Naruto fight, they will definitely use the moon. When Naruto enters the U-month space, the crow comes into play. The control of the moon world is in Naruto's hands, but Sasuke is disadvantaged.
U has seen the path Sasuke will take after his death, so he bets on Naruto. He does not want to see Sasuke and Naruto duel. If this means that Sasuke has been restrained by hatred, this It must be that U doesn't look like the result he saw, and whether to kill or not means that U, the crow, has the absolute ability for Naruto to defeat Sasuke, and in the monthly world, if Naruto controls the world, then Sasuke will really be manipulated by Naruto.
So this crow is when Sasuke used U's Sharingan to fight Naruto out of the moon, allowing Naruto to gain control of the moon space, allowing Naruto to defeat Sasuke in the world of U .
Of course, the above is purely personal speculation, and it depends on how Kishimoto draws it. There are many other speculations on the Internet, you can also take a look.
2 There are the following possibilities:
1 The Mangekyo Sharingan used to suppress Sasuke in the battle with Uchiha Sasuke (it is said in Chapter 488 of the comic that Sasuke has transplanted the one used by Uchiha Mangekyou Sharingan, the power of Uchiha Itachi existing in Naruto may transplant Sasuke's pupil power)
2 The power of Uchiha Itachi's pupil may strengthen the blood-stained boundary "flow pupil" of the Uzumaki clan The power of the (Eye of Uzumaki) may accelerate its eye opening
3 The Mangekyo Sharingan is a cursed eye that can subdue the Nine-Tails. The power of Uchiha Itachi's Eyes existing in Naruto's body will inhibit the leakage of the evil chakra of the nine-tailed demon fox (since the fourth Hokage Namikaze Minato first existed in Naruto's body, Itachi's power (spiritual chakra entity) ) will not appear before the fourth generation’s spiritual body disappears
