"Edo Tensei..." Madara chewed on the term.
He could understand Edo Tensei, but saying they were like Edo Tensei was a bit problematic.
'Could it be that there is another organization in this world, one we haven't discovered?'
Madara pondered.
But immediately, he shook his head.
'With the White Zetsu intelligence network, nothing in the world should be able to escape my notice.'
'Unless...'
Madara looked into the distance.
It was the direction of the sea.
Back in the day, Madara and Hashirama had discussed what lay beyond the sea, at the edge of the sky.
They had even planned to cross the sea together to see for themselves.
With their strength, traveling to the unknown ocean shouldn't have been a problem.
Unfortunately, plans couldn't keep up with changes. Konoha's affairs were busy, and after the village's founding, Madara and Hashirama quickly fell out. Ultimately, the plan was shelved.
So Madara was somewhat suspicious: "Could it be a force from beyond the sea, one we couldn't detect?"
As he spoke, he looked at Tobi, his eyes questioning.
Hearing Madara's words, Tobi thought for a moment and shook his head: "Madara-sama, I don't think it's likely. The White Zetsu's intelligence network is always active. If there were an external force, we would have discovered it long ago!"
"True." Hearing Tobi's words, Madara nodded with understanding.
But as he said it, he suddenly reacted.
"Wait!" Madara looked at Tobi: "So that's how it is!"
"So that's how it is?" Hearing Madara's words, Tobi was a bit confused: "'So that's how it is' means it's not like that now?"
"What do you mean, Madara-sama?" Tobi looked at Madara with confusion.
Seeing this, Madara explained: "Have you forgotten, Tobi? Because of a certain person, we've lost our intelligence network within the Land of Water!"
"Oh oh oh oh oh!" Hearing Madara's words, Tobi understood: "Indeed, we cannot monitor the Land of Water, and we only kept a few eyes there."
In that case, if the Land of Water couldn't be monitored, then it was easy to guess where these people came from.
Moreover, the Land of Water is a port nation on the sea.
Tobi looked tentatively at Madara: "Madara-sama, your idea is...?"
"Correct!" Madara nodded satisfied.
"Precisely that!" Madara explained: "It's possible there really is an external force, but we haven't seen them. And that kid Yuki Sora's strength... we've never truly seen its limits."
"If some external force is involved, and Yuki Sora is a person they created, just like I created Obito..."
"Then everything makes sense!"
As he spoke, Madara felt a chill run down his spine. A strong sense of crisis emerged in his heart: 'Damn it, has an external force really entered the Ninja World?'
"Namikaze Minato... it might really be Namikaze Minato! After all..."
Madara didn't continue.
But Tobi knew what he meant.
After all, that Rotting Wood Plague incident with the Uchiha was just too bizarre. Madara himself, including Tobi, and even Black Zetsu, didn't really understand it.
Tobi felt a sense of gravity inwardly, while Black Zetsu, lurking in the shadows, felt the same!
If it really was an external force, how was he supposed to resurrect his mother? How to split the moon and save his mother?
'No, the outsiders must be eliminated!' Black Zetsu decided inwardly.
He conveyed his thoughts to Tobi, instructing him to guide Madara.
At this moment, his thoughts aligned highly with Madara's.
Because in the very next moment, Madara also spoke: "No, the outsiders must be eliminated!"
Madara looked resolutely at Tobi: "I only want the Eye of the Moon Plan, to give everyone a beautiful future."
"But the situation with the external force is unclear. Regarding that Edo Tensei-like Namikaze Minato, and the Uchiha you mentioned, we can't discern what the external people want!"
"Speaking of this, I understand now. Yes, why has Konoha started using Edo Tensei, but they haven't reanimated Namikaze Minato?"
"Obviously, it's because they simply cannot use Edo Tensei Minato on him!"
"Namikaze Minato has already been controlled by the external force from the Land of Water. If that's the case, then that Rotting Wood Plague!"
Recalling the samples of the Rotting Wood Plague he had seen back then, Madara felt a chill in his heart.
He was the great villain of the Ninja World, sure, but that villainy was directed at the Ninja World.
It's like: I can harm the ninja world, but others cannot!
So upon discovering an external enemy, Madara quickly shifted his mindset.
As for the next course of action, Madara soon had an idea.
Madara looked at Tobi: "Call Obito back now, immediately!"
"Also, tell Obito he can go home once."
"Huh?" Hearing Madara's words, Tobi was utterly bewildered.
However, he carried out the order.
