Since Obito Uchiha had both considered and acted on the idea of using the Sharingan, he would certainly have stored the Sharingan he obtained.
Perhaps a few Sharingan had lost their viability for various reasons and been discarded by Obito.
But he must still have a large number of Sharingan stored somewhere.
Sasuke Uchiha was certain of that.
Sakura glanced at Naruto, then turned to Sasuke. "Since Sasuke says so, let's search some other places."
"We might really find something."
"What do you think, Naruto?"
Naruto did not argue. He simply nodded. "I'm with you, Sasuke!"
The reason he had suggested giving up on the mission earlier was that he genuinely thought Obito was unlikely to have any more Sharingan.
But since Sasuke insisted on continuing the search for the Sharingan, he had no objections.
Besides, Sasuke was the focus of this mission to begin with.
Since he had made his decision, Naruto and Sakura were willing to see the mission through with him.
Most importantly, Naruto and Sakura both understood Sasuke's fixation on the Uchiha Clan.
Now that the Uchiha Clan had been wiped out, any Sharingan that might still exist were Sasuke's only remaining solace.
Neither of them wanted to hold Sasuke back in this matter.
Still, this kind of search mission without a precise target really was even harder than they had imagined.
Of course, they had not come away entirely empty-handed.
At one secluded hideout, the three of them had found quite a few traces of Obito's past activities, and even some clues related to the Akatsuki.
But none of those places had shown any signs of Sharingan.
Only at the base the three of them had just searched had they found any Sharingan, but all of them had lost their viability and were completely useless.
