Konoha should have been one of the safest places in the shinobi world, and within Konoha, Tobirama Senju's laboratory ranked among the most secure.
To prevent experimental accidents or outside interference, Tobirama Senju had personally overseen its structural strength, privacy safeguards, and emergency measures.
Its security was so effective that Sensory Techniques could not probe inside. With so many different facilities and over a dozen entrances alone, Kagami Uchiha had no real option but to search them one by one through a process of elimination.
Along the way, he not only struggled to find them but also had to endure a sudden, searing pain somewhere on his body.
By the time he finally smelled blood and found the right place, Uchiha Ichiro's body had already gone cold.
He rounded the corner and came face-to-face with Black Zetsu. Their eyes met, and in his overwhelming grief, his rage awakened his Mangekyo.
Yet Black Zetsu's suffering was no less than Kagami Uchiha's. If they were comparing sheer agony, he even had a slight edge.
The Rinnegan! My Rinnegan!
My four great big Rinnegan eyes! All four of them! Where did they go?! He gesticulated wildly.
Ah, I see! This time, the Rinnegan disappeared outside Tobirama Senju's laboratory. Last time, the Stone Tablet disappeared inside the Uchiha District. What did they have in common-
They were both in Konoha!
I get it! Konoha is the problem!
Konoha and I just aren't compatible. All I need to do is purge the whole village.
Kill all the adults and leave only the young children who are easy to control!
Then raise them and have them give me twins, triplets, quadruplets!
Then make them slaughter each other! Awaken the Mangekyo! Awaken the Eternal Mangekyō Sharingan! Awaken the Rinnegan!
*My plan! My plan will be realized any
