Let me tell you, when Uchiha Madara was still alive, he already knew Nagato, knew that Nagato had the Reincarnation Eye, and even knew that Nagato would be able to "reincarnate the art of birth" when he grew up.

Uchiha Madara here said: This brat Nagato has grown up a lot... The key text here is: "That kid", which means that the Nagato that Uchiha Madara saw before he died was little Nagato. Another key word is "growth". Growth here should not refer to age, but to the growth of Nagato's reincarnation eye power. Because Madara Uchiha, who had just been summoned, believed that he was resurrected because Nagato used the power of the Samsara Eye - the art of reincarnation.

Since Uchiha Madara initially thought that he was resurrected by the reincarnation technique, I can conclude that Madara, who is currently talking to the second Tsuchikage, has not yet been controlled by Kabuto, so Madara thinks that The ninjutsu he was resurrected was a reincarnation-born jutsu based on the power of the Rinnegan Eye, rather than a filthy earth reincarnation jutsu invented by the Second Hokage. Why do you say that? Because the masked man once said that the reincarnation eye was given by him. And why choose Nagato? Because Nagato, like Naruto, has a sage system, so it is best to use it as a test subject. It's just that Nagato's walking route did not meet the masked man's expectations...

In the 560 comics. That guy is undoubtedly the masked man. Combined with the reincarnation technique he mentioned in the previous chapter, the agreement Madara mentioned was nothing more than the masked man's promise to use that technique to resurrect him. But now the masked man obviously didn't do it, but made his own little calculation. On what favorable terms did Master Madara get the masked man to agree to resurrect him? This makes other people think it is a bit interesting. This man is dead. Why did Madara have the confidence that the masked man would resurrect him as promised? And looking at him now, knowing that he was not resurrected but just exposed from the dirt, he can still be so calm. He is worthy of being a man who stands at the top of Uchiha. What is the identity of the masked man that allows Madara to trust him so much and entrust him with such an important task? I am afraid that this secret will finally be revealed by Madara. Let’s look forward to it together.
