Obito's Right Eye Kamui did not have the ability to directly tear enemies apart. The main offensive power of his Mangekyō Sharingan was stored in his left eye, but his left eye was in Kakashi's eye socket. Kakashi, who was not a member of the Uchiha Clan, did not have the ability to use the Sharingan proficiently...
However, to make his teammates understand the threat posed by the person before them, that did not stop Yuhara from scaring them with such a claim.
But after Yuhara and Captain Furry had anxiously exchanged a couple of "friendly" words, Kizuna suddenly spoke from the side. "The enemy seems to have disappeared."
Just as Yuhara finally made his teammates understand how powerful the enemy was, Obito had actually "run away"... That was only natural. Obito had not come to Konoha to exchange Ninjutsu with the Anbu.
The fact that he had failed to eliminate Yuhara and the others instantly had been somewhat beyond Obito's expectations. Yuhara's "precise" analytical ability had made him realize that the longer he lingered here, the more information about him would be exposed. However, his own exposure was not entirely bad. Since he could no longer infiltrate secretly, he might as well draw a large number of Anbu ninjas over here and then go do what he wanted.
The mobilization of the Anbu ninjas would help him locate the Jinchuriki.
Then Obito heard another whistle. Immediately afterward, the Anbu ninjas who had been moving suddenly stopped and began standing guard where they were.
"The enemy has disappeared. Reinforcements are canceled. Concentrate on guarding. Protection takes priority."
After Obito disappeared, Yuhara and the others immediately realized what he was trying to do, so they sent out this signal... Don't run around. Protecting the Jinchuriki was the top priority.
In any
