Everyone Wants It

"What do you think of this Uchiha clan compound? I could give you all of... no, I can give you half of the clan compound."

"Is my name going on the property deed?"

Naruto Uzumaki looked at him with a strange expression and said, "Forget it, I don't want your clan compound. Give me two hundred thousand ryo, cooperate with me on an experiment, and then I might consider helping you with your training."

Uchiha clan compound.

Sasuke's house.

In the living room, Sasuke placed his hands on Naruto Uzumaki's shoulders, continuously channeling his Chakra into Naruto Uzumaki's body.

A few minutes later, Sasuke's internal Chakra was completely exhausted. He lowered his hands and looked at Naruto Uzumaki, who was sitting with his eyes closed in deep thought.

This guy... is getting weirder and weirder.

He had demanded a Chakra transfer for no apparent reason, and Sasuke had no idea what the point of it was.

This shouldn't be right. There hasn't been a single change in my ocular power. So much for the theory that Indra plus Asura equals the Rinnegan...

Even after the Chakra Sasuke had channeled into him dissipated completely, Naruto Uzumaki's Rinnegan showed no signs of change.

He opened his eyes, frowned in contemplation, and after a long while, looked up at Sasuke.

"Now it's my turn to channel Chakra into you."

Ten minutes later.

"Why... is your Chakra able to increase my ocular power?!"

Sasuke touched his own eyes, his expression filled with deep confusion.

Ocular power didn't grow like this. Wasn't it supposed to be developed slowly through training or grow naturally over time? Why could it be increased by receiving someone else's Chakra?

This defied all logic of ninjutsu!

Naruto Uzumaki didn't explain, instead saying, "Let's go to the kitchen."

It took half an hour for Naruto Uzumaki to convince his parents, who were barely able to tolerate his bizarre behavior.

Under Sasuke's slightly terrified gaze, Naruto Uzumaki pinched his nose and drank half a bowl of fresh blood that had flowed from a cut on Sasuke's wrist.

After waiting for a long time, Naruto Uzumaki finally felt a change in his ocular power.

"My ocular power... increased by a tiny bit."

It was very little, almost negligible, but that didn't matter; the significance was profound.

It meant that Naruto Uzumaki's line of reasoning was correct. He could upgrade his Rinnegan by collecting Indra's Chakra or through other similar methods.

Three Tomoe, Six Tomoe, or even Nine Tomoe... they were no longer just dreams.

"You drink a bowl of my blood, too."

Naruto Uzumaki gritted his teeth and cut his wrist, filling half a bowl with blood before handing it to Sasuke.

"I'm not drinking that. I'm not a pervert; how could I possibly drink human blood?"

Sasuke shook his head repeatedly, stepping back with clear resistance.

"I'm not a pervert either!"

Naruto Uzumaki darkened his face and shoved the bowl at Sasuke. "If you want to gain the strength to take your revenge, then drink it... Of course, if you don't want to, just pretend I never said anything."

Sasuke naturally wanted revenge, but drinking blood...

Sasuke hesitated. "Will it increase my ocular power like the Chakra transfer did before?"

"Maybe it will even help you awaken the Two Tomoe."

Even Naruto Uzumaki didn't believe his own words. Sasuke had only just awakened the Single Tomoe; how could he possibly...

What the hell!!! This isn't right!!!

"You actually awakened it!!!"

Naruto Uzumaki widened his eyes, staring at the Two Tomoe in Sasuke's right eye. He thought the effect was far too significant—it was like night and day compared to his own results.

He became increasingly certain of his hypothesis—

His own Asura Chakra had a certain degree of stimulating power, which was why both his Chakra and his blood could affect Sasuke.

Meanwhile, Sasuke's Indra Chakra was hidden deep within his body, which was why Sasuke's Chakra was useless to him, but Sasuke's blood was effective.

Does this mean I have to drink Sasuke's blood every day?

No way!

That's too disgusting. I'd rather not upgrade my Rinnegan.

I have to find another way. I could ask the Sage of Six Paths for a cheat, ask the Tailed Beasts for Chakra, or help Sasuke improve his Sharingan to increase the development of his Indra Chakra...

Looking at his reflection in the mirror, with a Single Tomoe in his left eye and a Two Tomoe in his right, Sasuke—whose nerves had been taut ever since the destruction of his clan—showed a relaxed smile for the first time.

He clearly felt that his dream could come true.

It was not just a final shred of stubbornness born from despair.

"Itachi Uchiha, I will soon obtain power equal to yours... no, power that surpasses yours, and then... I will kill you!!!"

Suppressing the boiling killing intent in his heart, Sasuke turned to make a request of Naruto Uzumaki.

Blood, Chakra, soul energy...

Sasuke wanted all these things that could enhance his strength.

But Naruto Uzumaki only gave him Chakra and soul energy; he refused to give blood, citing that it was too disgusting.

After tossing and turning until evening, Sasuke failed to fulfill his wish of becoming a full two-tomoe user.

The two agreed to continue later.

Over the next few days, Naruto Uzumaki gave Sasuke whatever he asked for, even slapping his own face by providing several bowls of blood, all so that Sasuke could awaken the power of Indra as quickly as possible to be of help to him.

However, one cannot pull up a seedling to help it grow.

The evolution of the Sharingan required intense mental stimulation; Naruto Uzumaki's blood, Chakra, and soul energy could only act as catalysts to reduce the difficulty, not fully replace the process.

Should he intentionally provoke Sasuke?

Under the ear-tugging education of Kushina, Naruto Uzumaki dismissed this idea of provocation.

Subsequently, Naruto Uzumaki said to Sasuke, "Let's pause the experiments. From now on, I won't give you my blood. I'll give you Chakra once a day, and soul energy and Life Energy once a week... In exchange, you will also channel Chakra to me once a day. Any problems?"

"None!"

Sasuke nodded in agreement. He was well aware that he was the one benefiting from this arrangement.

A dark night with a high wind is the perfect time for murder and arson.

Konoha was shrouded in the veil of night.

A spatial vortex twisted, and Obito stepped out from it, appearing outside an ordinary apartment building.

"Tell me the recent situation of the Nine-Tails Jinchuriki."

A White Zetsu emerged from the ground and replied, "As usual, other than attending school, the Nine-Tails Jinchuriki spends his time training with Sasuke Uchiha."

"The Jinchuriki is actually training with an Uchiha. It seems Itachi's efforts were not in vain; his younger brother has already gained the recognition of Konoha..."

With a mocking laugh, Obito asked, "Have you noticed anything unusual? Any abnormal actions or suspicious people?"

The White Zetsu said decisively, "No!"

"Useless trash!"

Waving his hand to dismiss the White Zetsu, Obito looked up at the apartment building, a red light flashing in his eyes before his figure vanished.

In the dim bedroom, a young boy lay on the bed, fast asleep, looking as though he wouldn't wake up easily.

The spatial vortex twisted, and Obito appeared at the edge of the bed. Looking at Naruto Uzumaki with neither joy nor sorrow, he drew the Katana tucked at his waist.

Swish!

A cold glint flashed as he cruelly slashed at Naruto Uzumaki's neck.

"Not good!!"

The moment the blade struck the neck, Obito felt that something was wrong and immediately attempted to activate Kamui to shift into his intangible state.

But it was too slow!

A Rasengan slammed into Obito's back.

Boom!

His body was pierced through, the floorboards were shattered, and a massive sound echoed in all directions, breaking the silence of the deep night.

"Enemy attack!!!"
