From the night of genocide, marching towards the strongest.

Upon hearing this, Obito's face darkened. He knew what Nagato wanted to ask, but he did not answer Nagato's question immediately.

Instead, as usual, he naturally intended to sit on the sofa in the room, and just as he was about to sit down...

Obito felt a chill run down his spine, and a certain indescribable place was throbbing with pain. He subconsciously tightened his buttocks.

He looked rather strange.

Nagato and Konan didn't notice anything wrong with Obito either, or rather, their minds weren't on him at all. Seeing that he didn't speak, they continued to ask, "How is he? What about Yahiko's body?"

Obito pondered for a moment, then shook his head and said in a deep voice in Madara Uchiha's tone, "I'm sorry, Nagato, I was unable to stop Sasuke Uchiha."

"Now that Uchiha Sasuke has gained momentum, even I, in my prime, would have to put in some effort to defeat him. And now, my injuries from the battle with the First Hokage have not yet fully healed."

As he spoke, Obito's face flushed red, and he also felt a slight pain.

However, with the mask concealing his identity, neither Nagato nor Konan noticed anything amiss with him.

"Thank you for your help, Mr. Madara!"

A flicker of pain crossed Nagato's face, then he took a deep breath and said with chilling killing intent, "Use our intelligence network and Zetsu's clones to find them!"

"Find Uchiha Sasuke, no matter where he is hiding in the ninja world, even if we have to turn the entire ninja world upside down, we must find him!"

“Alright!” Obito nodded, his tone equally cold, and said, “This time, we’ll join forces to find him!”

...........

As Obito Uchiha returned to his base, Zetsu's figure emerged from the room.

"Obito, it seems you've lost this time."

"He lost to Uchiha Sasuke!"

Upon hearing Sasuke's name, Obito Uchiha felt a throbbing pain in that area again. He took a deep breath and said in a low voice, "This time it was just carelessness. Next time it won't be so easy."

"I think it's more than just carelessness, isn't it?"

Black Zetsu said in a heavy tone, "You used Izanagi, which means you have lost completely this time!"

Upon hearing this, Obito's face immediately darkened.

"Were you spying on me?"

At this moment, Obito felt a little panicked. Could he have seen his disheveled appearance from before?

Black Zetsu shook his head and said calmly, "I didn't know the details of your battle with Uchiha Sasuke, but I noticed that one Sharingan was missing from the Sharingan storage cabinet."

"As for surveillance?"

Black Zetsu's tone remained indifferent: "I was originally created by Madara to supervise you in carrying out the Eye of the Moon Plan. There's no question of surveillance or not. I think you should understand that, right?"

Obito frowned slightly, turned to look at Zetsu, and said in a deep voice, "So, what do you want to say?"

"Summon Madara!" Black Zetsu said directly.

"impossible!"

Without a second thought, Obito coldly rejected him.

"Uchiha Sasuke is just a negligible variable. Everything is still under my control. There's no need for Madara to get involved!"

"Heh, Obito, I know you have other thoughts in your mind, but..." Black Zetsu chuckled sinisterly.

"Now that Sasuke Uchiha has gained the upper hand, even if Nagato himself were to take action, he might not be able to kill him. In order to ensure that the plan does not encounter any unexpected problems, we have no choice but to summon Madara!"

"As long as he makes a move, even though Sasuke Uchiha is strong now, he's nothing compared to Madara's strength!"

"no!"

Obito rejected Black Zetsu's suggestion again, looking directly into Black Zetsu's eyes, and Black Zetsu met his gaze without flinching.

The atmosphere instantly became tense and frozen.

Realizing that there was a change in the status quo of this generation of Indra, Black Zetsu decided to completely eliminate this variable.

Only Ashura can fight against Indra, but the difference in strength between Indra and Ashura in this generation seems to be quite large.

If Asura doesn't work, then we'll use the previous generation's Indra.

"Give me a little more time." Obito breathed a sigh of relief and lowered his stance a bit.

"It will take more than two years for the Three-Tails to revive, and Madara's Rinnegan also needs Nagato to continue nurturing it. The Gedo Mazo is only in its initial stage of awakening."

"Even if we summon Madara, we will still need to wait two more years to complete the Eye of the Moon plan."

"Two years. Give me two years. If I still can't defeat Uchiha Sasuke by then, then I'll summon Madara again!"

Upon hearing this, Black Zetsu gave Obito a deep look and said in a deep voice, "I will decide based on the situation."

Black Zetsu neither agreed nor refused.

The implication is that when he feels Obito is unable to control the situation, he will summon Madara in advance.

Obito naturally understood, and remained silent for a while.

"Go and bring me Madara's weapon, and while you're at it, wake up Tobi."

Madara Uchiha's weapons are named the Death Scythe and the Flame Fan.

Only Black Zetsu knew the location of Madara Uchiha's body. When Madara died, the two divine weapons were buried with him.

Only Black Zetsu can obtain it.

The Death Scythe and the Flame Fan are divine weapons passed down through generations of the Uchiha clan head; they are physical weapons!

The Totsuka Blade and the Yata Mirror are spiritual weapons, illusory objects!

These four weapons are the four sacred treasures of the Uchiha clan!

If we add the Fire Armor that Sasuke currently possesses, then the Uchiha clan will have five divine weapons.

"Okay! I'll bring these things to you later."

After saying that, Black Zetsu's figure gradually disappeared into the earth.

"Wait a moment!"

Obito Uchiha suddenly called out to Black Zetsu, who was about to leave.

"what's up?"

After pondering for a moment, Obito Uchiha asked, "Where's Itachi?"

"He's with Xiao Nan."

Black Zetsu chuckled sinisterly, "However, his current condition is not ideal. He remains unconscious. Although Konan has sent the best medical ninja from Amegakure to treat him, he is unlikely to wake up unless something unexpected happens."

"So that means he's going to die?"

Obito Uchiha murmured to himself, sounding somewhat anxious.

"Hmm!" Black Zetsu nodded and said in a deep voice, "His life is hanging by a thread now. At most, he will die silently in his hospital bed in six months, or even less."

"I see."

"hehe...."

Black Zetsu glanced at Obito and slowly said, "Obito, I think it's time for you to give up all your bonds and take back what's rightfully yours."

After leaving behind those words, Black Zetsu completely disappeared from the room.

Only Obito remained silent.

Chapter 231: The Feasibility of Reverse Deduction of the Rinnegan?

One day later, at night.

The night was gloomy, and darkness enveloped the silent night sky. Only a crescent moon hung alone high in the sky, occasionally disappearing into the clouds, revealing only a few specks of light.

In the underground base of the Sound Village.

"Naruto's cells have been injected!"

Sasuke slowly rose from the nutrient tank, clenched his fist, and after sensing his body's condition, murmured, "My strength and recovery have increased a little, and I can also feel that with the injection of Naruto cells, the rate at which my redifferentiated Sage Body cells have accelerated by at least 20%!"

The Uzumaki and Senju clans are distant relatives, both tracing their origins back to the Otsutsuki Ashura.

Both Naruto Uzumaki and Hashirama Senju are reincarnations of Ashura's chakra.

The fusion of the two cells proceeded incredibly smoothly without any rejection.

It could even be said that the two are essentially one entity.

They only differ in their outward characteristics, but they share the same origin!

After receiving Naruto's cells, Sasuke could clearly feel that his bone marrow stem cells were producing blood much faster.

Sasuke originally estimated that without the support of Naruto's cells, it would take him at least 7-8 years to completely transform his entire body into new Sage Mode cells.

But now that timeframe has been reduced by half, to 3-4 years.

"If the Hagoromo clan is also a descendant of the Sage of Six Paths..."

Thinking of this, Sasuke's eyes flickered slightly, and he murmured, "At this rate, I only need two years, or even less!"

After calming himself down, Sasuke extended his right hand and gathered chakra, and clusters of sharp, invisible energy appeared in his palm.

"The time it took to awaken the wind attribute chakra this time was also much faster than before."

After the last injection of Hashirama's cells, it took Sasuke about three days before he was able to use water and earth chakra to a basic level.

And now, Sasuke has only spent one day!

"call....."

Sasuke breathed a sigh of relief, put on his clothes, instructed his shadow clones to clean up the place, and then walked out of the laboratory and headed towards another laboratory.

He gained a lot this time, but there is still a lot to do.

Now is not the time to rest.

............

Three days later!

In another laboratory.
