In the original plot, Obito had a single Rinnegan for a while. But he basically never used Rinnegan's abilities. Shinra Tensei, Banshō Ten'in and the like are basically useless.
He mostly uses his Kamui to fight.
Maybe it's because Rinnegan's skills consume too much. Or maybe Obito is not used to using Rinnegan.
The truth about Aoba is unknown. But when Black Zetsu controlled Obito's body, he constantly used Rinnegan to fight.
This also caused the Minato and Kakashi originally prepared for Kamui to be unable to win Black Zetsu for a long time.
But as the battle continued, Minato felt keenly that Black Zetsu on the opposite side seemed to be getting a little impatient. His Rinnegan ability was used less and less, and he even took the time to use Kamui several times to avoid the attacks of the two of them.
However, the time was too short and Kakashi did not find a suitable opportunity to make a move.
But this still gave Minato an extremely obvious signal. For some unknown reason, Black Zetsu seemed to be in some kind of trouble.
Minato guessed that Rinnegan consumed too much. The previous battle, and then the forced escape from the prison, it is impossible that there was no consumption at all.
Obito's body was already riddled with holes. After repeated tossing, he still had to bear the consumption of one Mangekyō and one Rinnegan. The burden was completely exhausted.
If Black Zetsu were in full strength, it should be able to withstand it. However, in the last ambush, Black Zetsu lost part of Clone Technique's body. It itself was also in a state of weakness. In this way, in the face of this kind of consumption, it began to seem more and more powerless.
Black Zetsu knows that he must leave. Although Madara Uchiha is important, it is not absolutely irreplaceable. If it doesn't work, he will go back and continue to wait for the next opportunity.
But if you are caught or killed here, then you are really doomed. I used the trick of golden cicada to escape its shell once before, and it is almost impossible to succeed again.
After synthesizing various information, Black Zetsu no longer tried to join Madara Uchiha, but tried to escape.
This move was immediately captured by Kakashi and Minato Namikaze. As Hokage, one of the two people with the highest ninja ability. They both saw through Black Zetsu's movements almost at the same time.
"He wants to escape." The two exchanged glances to make sure that the other party understood this. Then they accelerated the pace of the attack.
And Black Zetsu also changed his evasive play. Suddenly he became fierce and directly used Hellish Chaos, forcing Kakashi and Minato back.
Minato and Kakashi subconsciously thought that the other party was planning to use Space Vortex to escape. The special trait Flying Thunder God Kunai in their hands was ready and ready to interfere with the other party's departure at any time.
Facing two Flying Thunder God, it is almost impossible for Black Zetsu to escape intact.
But at this time, Black Zetsu made an unexpected move. He suddenly reached out and dug out the Kamui Mangekyō from his right eye. Then, he stuffed another Rinnegan directly into the eye socket.
At this time, Kakashi and Minato knew that their judgment was wrong. Because Black Zetsu's avoidance style from the beginning gave them an illusion. That is, Black Zetsu was eager to escape and did not want to fight with them head-on.
In a sense, their judgment was correct. Unfortunately, when Black Zetsu judged that the cost of continuing to fight was too high and exceeded the Madara Uchiha chess piece, everything changed.
Black Zetsu's body is floating in the air, with his hands stretched out.
"Shinra Tensei."
The Wood Release forest created by Yumi Wood Clone was directly shattered by the violent shock wave. Even a small half of Amegakure was bulldozed.
This is because the Wood Release forest absorbed most of the shock wave. Otherwise, this blow would directly level the entire Amegakure.
Kakashi and Minato tried to use Flying Thunder God to dodge. However, they did not have too many Flying Thunder God Mark in Amegakure. They also suffered damage from the shock wave.
Fortunately, the two of them responded in advance. With sufficient chakra, they put up some resistance. Although they were injured, it was not fatal.
It can only be said that among all the abilities of Rinnegan, Shinra Tensei is really one of the most versatile and useful abilities.
The indiscriminate shock wave can target almost all tactics.
Aoba and Madara Uchiha were also hit by the shock wave. However, they were stronger and basically did not suffer much damage.
But this shock wave interrupted the fight between Aoba and Madara. Both of them guessed what happened.
Aoba did not expect that after so much trouble, Black Zetsu would dare to transplant two Rinnegan into the body of Obito. Madara knew that since Black Zetsu was risking his life, it meant that the battle on his side was coming to an end.
Black Zetsu floating in the sky stretched out his right hand and aimed at Madara Uchiha. It wasn't that he didn't want to strike again and completely eliminate several Konoha ninjas. It was just as Aoba guessed.
After Obito's body had withstood countless tortures, it was almost unable to hold on. At this time, he could only reluctantly use Banshō Ten'in and try to take Madara Uchiha away.
But Aoba and the others would naturally not be able to watch him take away Madara. In that case, this battle would be considered a total loss.
The three Flying Thunder God Kunai shot almost simultaneously. Minato and Kakashi were the first to approach the flight path of Madara Uchiha. The three of them fought in mid-air.
And at this moment, they felt the power of Madara Uchiha. Even in high-speed flight, Madara Uchiha still easily suppressed the two of them. In the short fight, the two could not find any chance to leave Flying Thunder God Mark on Madara's body.
It can only be said that although Madara Uchiha does not know how to Flying Thunder God, he is actually very familiar with this move. The moment the two of them got close, he knew what they wanted to do and easily defused this wave of offensive.
But then, Aoba also appeared behind him.
"Wait a minute, why behind?"
Madara Uchiha was confused. He had played against Aoba twice and knew that the opponent's tactical level was absolutely top-notch. It was impossible for him to make meaningless actions. But using Flying Thunder God to teleport behind him, something was obviously wrong.
Because my body is flying forward. You teleport behind me, and the next second I fly away. What are you doing to stop me?
The previous two Flying Thunder God ninjas were teleported in front of me and intercepted.
But then Aoba's actions made him realize that something was wrong. Because Aoba did not attack him. On the contrary, he was surrounded by a high-speed tornado, supporting him to fly in the air.
He did not attack Madara. Instead, he flew after him.
At this time, the two of them had already approached Black Zetsu. Aoba suddenly pulled out his knife, and Kusanagi Sword stabbed Madara Uchiha. Madara subconsciously twisted his body and avoided the blow by a hair's breadth.
But then Aoba's blade suddenly extended past his body and stabbed into the air.
"Oops, his target is Black Zetsu." Madara understood Aoba's actions. But it was already a little too late.
