Without a doubt, this pair of Mangekyo belonged to his grandmother, Chiri Uchiha!
This blood connection was very easy to identify. When Shinji activated 'Susanoo Lamp' to control this pair of Mangekyo, he encountered almost no rejection. It was far easier than controlling Fugaku's pair of Mangekyo before.
"Found them!"
Shinji was overjoyed!
Not only had he found his grandmother Chiri Uchiha's Mangekyo, but he also discovered that this pair had been preserved far better than the previous two.
This further confirmed his theory.
The condition of the Mangekyo itself also affected the degree of corruption.
The owners of the previous two pairs had clearly consumed a great deal of their Mangekyo's Dojutsu while alive, whereas Chiri Uchiha's pair had suffered much less depletion, so it had been preserved in better condition.
After calming the joy in his heart, Shinji began to ponder.
Three pairs of Mangekyo had come out of ten jars. Although one pair had already decayed beyond use, the haul still far exceeded his expectations.
But now, a new problem had emerged!
Both usable pairs of Mangekyo had used Forbidden Jutsu and permanently lost the Dojutsu in one eye.
They were incomplete.
Shinji had sensed it with 'Susanoo Lamp.' Even his grandmother Chiri Uchiha's pair of Mangekyo could not be fused directly because its Dojutsu was incomplete.
"How can I restore these two pairs of Mangekyo?"
Shinji rubbed his chin.
Restoring permanently blinded Mangekyo was not actually impossible. Madara Uchiha had accomplished it in the original timeline.
His world-shaking battle with the First Hokage had ended with him using 'Izanagi' to fake his death.
Afterward, he studied the First Hokage cells and combined Yin Release with Yang Release. Before his death, he finally drew forth the 'Power of All Things,' where Yin and Yang became one. Not
