Uchiha Obito
As for the method to break the seal, there is only one: the Sharingan! Because this baby was created using Uchiha Meigetsu's cells as the center!
Therefore, the Uchiha Clan bloodline is the most crucial element! Once the Sharingan is awakened, this child's potential will be unleashed! At that time, they will definitely grow very quickly!
However, awakening the Sharingan is not easy. If Indra's reincarnation could awaken the Sharingan with the slightest stimulation, then an ordinary Uchiha Clan genius would awaken it three times faster than that. Another ordinary Uchiha Clan would awaken it five times faster. But this child's awakening is twenty times, or even fifty times, faster than that!
In other words, without experiencing great sorrow and joy, one cannot awaken the Sharingan or break the seal.
At this moment, White Zetsu silently watched Kangetsu.
Kangetsu listened to White Zetsu's words, her eyes filled with joy as she looked at the infant. She then said softly, "Perfect, perfect! This child will be named Uchiha Obito. In a while, send him to the Uchiha Clan of Konoha. Bring a letter from me; I think they'll know what to do! This child is also a descendant of Meigetsu. He's also the successor I've chosen for Izuna!"
At this moment, White Zetsu was somewhat puzzled. He couldn't help but ask, "Lord Kangetsu, why is the successor you've chosen for Izuna? Lord Izuna is alive and well now; in terms of lifespan, he could probably live for another hundred years or more."
Kangetsu shook her head and said, "A hundred years, that's not what I want! Now, the Second World War has begun. Apart from the small ninja villages that have been wiped out, there's also the upcoming Four Villages War. Leaving aside the number of deaths, just consider this: all the second-generation ninjas of each village are dead. So, the newly elected third-generation ninjas are no match for Izuna."
Moreover, due to the deaths of the second-generation leaders of various villages, coupled with the recent great war, this is a period of peace. During this period, apart from our Blood Ninja Village, the remaining villages are simply not worth Izuna to play with!
I estimate that Izuna will be able to fulfill Madara's wish and plan within this timeframe. This is not what I want, because now is not the time for that guy to be resurrected. Therefore, Izuna, I have already arranged three Kage opponents for him. At that time, the combined attacks of the Second Kazekage, the Tsuchikage, and the Raikage will at least severely injure Izuna, if not kill Izuna. By then, Izuna will be like Uchiha Madara, and naturally, he won't be able to carry out his plans during this peaceful period.
Therefore, Uchiha Obito's appearance marks the new beginning of the plan. That will be the time I desire. Therefore, this Uchiha Obito will replace Izuna!
White Zetsu was taken aback for a moment, then said, "Lord Kangetsu, wouldn't it be better to revive the Ten-Tails now?"
"Of course it's not good. I'm not ready yet, and the new generation of Asura and Indra haven't been reincarnated. In addition, I'm not ready with the methods to deal with the Ten-Tails, so this plan has to be delayed. I'm delaying this plan, but Izuna and Madara want to speed it up."
This led to a direct conflict, which is why I had to stop the plan and act according to my wishes. However, the plan cannot be stopped permanently, which is why Obito appeared."Kangetsu said calmly.
