Naruto Shippuden Manga Episode 510: A Shocking Forbidden Technique

Naruto Shippuden Manga Episode 510: A Shocking Forbidden Technique is the continuation of the  Naruto Manga Series with the last episode Naruto Shippuden Manga Episode 509: The Bridge to Peace.

From the last episode... It is between Konan and Madara.  As
Madara falls into Konan's sea of papers he holds his mask and tries to use his space-time but the exploding fuda prevents him from doing so. It appears that in order for Madara to teleport he needs to be materialize first. Konan prepared six hundred billion exploding fuda which will continue to explode for ten minutes and Madara can only slip through materials for only five minutes. As Madara starts to be covered by the papers a flashback came to Konan and as the explosion ends the paper decoration in her hair crumbles a sign that she exhausted her chackra from that last technique. She expects that technique will kill Madara but she was wrong. From behind Madara spoke stab Konan. Madara uses Izanagi a forbidden technique by the Uchiha clan that turns illusion into reality, he claims that only the one who holds the power of the Uchiha and Senju clan can use this Dōjutsu. Konan replied that this is a Rikudō's (Sage of the Six Paths) power. Madara reveals that the truth when he fought Senju Hashirama even the world thinks that he lost to Senju Hashirama but the true victory and defeat come after the battle back then was to gain the person's power. He told Konan that "I am Uchiha Madara who obtained Senju Hashirama's power. The second person to become Rikudō (Sage of the Six Paths), that is my sole existence now. There were a few others who displayed imperfect Izanagi because they couldn't control Hashirama's power, but...". Konan stands up and say that the will of Yahiko and Nagato will not vanish and he believe in Naruto and he will become the bridge of peace and for that she will be the pillar, the sky clears up and the sun appears together with the rainbow. She raises his hands and the paper forms a circle she was grabbed by Madara on the neck and told her that he will make that rainbow bridge together with the seven sparkling colors disappear into the darkness, as the moment this genjutsu end she will end as well. Konan loses consciousness. And it appears that Madara found out where the corpses of Yahiko and Nagato is. The last scene shows that Madara is sitting next to Nagato and saying "You are the third Rikudō'... [Holding] a power so strong, it was even able to turn your red hair, proof of your Uzumaki clan lineage, into white... You turned traitor and yet you still smile...?"

The last dialogue appears to be saying that
Nagato and Naruto are both came from the same clan which is the Uzumaki clan... And the big question here is that if Madara is the second and Nagato is the third is Naruto the forth Rikudō'?
