Both time-traveled characters ended up as villainous henchmen.

"Wait? You're going to participate in the Chunin Exams?!"

Obito was shocked, and even the Ichiraku Ramen in his mouth fell back into the bowl.

"Didn't you just graduate from the Ninja Academy not long ago?"

Obito hurriedly stood up from his chair, staring directly at Izumi Nen beside him.

"There's nothing we can do about it; being exceptionally talented is just like that."

Izumi calmly picked up a mouthful of ramen and said indifferently.

Obito's face flushed red with anger. He opened his mouth to say something, but couldn't utter a single word.

A moment later, Obito's energy completely dissipated, and he slumped back into his chair, listlessly picking at the noodles in his bowl with his chopsticks.

Ichiraku Ramen no longer appealed to him, and even the fact that he was about to meet the graduation requirements of the Ninja Academy didn't make him happy.

My life suddenly became dark and hopeless.

"Don't worry, Obito. You are a man who carries the name of the Uchiha. Once you awaken your Sharingan, becoming a Chunin will be a piece of cake."

Seeing that Obito seemed to be dying, Izumi Nen offered a word of comfort.

Obito's expression improved slightly upon hearing this, but Izumi's next words almost made him choke.

"Just wait and enjoy my Chunin promotion feast! Don't worry, there'll be plenty of barbecue!"

Obito was speechless, and could only channel his grief and anger into his appetite, swallowing large mouthfuls of Ichiraku Ramen.

As Izumi Nen watched Obito's agitated state, his originally dark pupils gradually turned a deep purple.

Purple Nether Eyes.

From this unique perspective, Izumi Nen could see everything from Obito's blood flow to the neural electrical signals in his body that changed with his emotional state.

Izumi Nen also focused his attention on Obito's eyes and brain area.

As expected, the blood flow and nerve signal transmission in the eyes and brain of the Uchiha clan are very different from those of ordinary people.

The Uchiha clan is greatly affected by emotions. Blood flow and nerve signal transmission are both affected by emotions, and they may even exhibit conditions that are impossible for ordinary people.

In addition to the more subtle chakra flow and deeper chakra nature changes, all these conditions combined are necessary for the Uchiha clan to achieve the Bloodline Limit Awakening.

Despite this observation alone, Izumi Nen was unable to uncover any deeper secrets about the Sharingan of the Uchiha clan from Obito.

However, he still managed to glean some insight into the direction of Obito's eye power usage from these hidden changes in him.

If he has sufficient data records related to the Sharingan, then it wouldn't be difficult for him to directly imitate some of the Sharingan's abilities using the Purple Eye.

Izumi Nen really wanted to go directly into the Uchiha clan's territory with Obito to observe a few Uchiha who had awakened their Sharingan, but he knew that with his still immature Purple Nether Eyes, it was wishful thinking to think he could contend with the mature Sharingan bloodline limit.

There's a very high chance that he'll be discovered by the powerful members of the Uchiha clan as soon as he starts spying.

The consequences of doing so are currently beyond the capacity of Izumi Nen to bear.

Furthermore, this type of eye-based ninjutsu, which can be trained, is not suitable for directly appearing in front of a family with a bloodline limit for eye techniques.

Whether it's the Uchiha or the Hyuga.

Suppressing the jumbled thoughts in his mind, Izumi Nen got up to pay the bill.

Obito didn't say much, only leaving Izumi with a sorrowful and indignant figure, just short of saying "Thirty years have passed, the river flows east."

Izumi Nen paid no attention to Obito and wandered around the commercial district of Konoha Village after leaving Ichiraku Ramen.

At the same time, he secretly activated the Purple Nether Eye, observing the blood flow and nerve signal transmission of civilians and other ninjas on the street, silently accumulating raw data.

He could sense that this recording and analysis of massive amounts of relevant data could also help his Purple Nether Eye evolve further.

However, due to the differences between worlds, this evolutionary effect is not as obvious as it was in the Digital World.

Chakra is the most important thing in the ninja world. For his Purple Nether Eye to evolve further, he also needs a more powerful dojutsu bloodline chakra.

Izumi Nen wandered aimlessly through Konoha Village.

While adapting to his newly evolved Purple Nether Eye, he also used the Purple Nether Eye to collect relevant data on the eye areas of various groups of people in Konoha Village.

Before long, an extremely large source of chakra appeared in Izumi Nen's perception.

Beside this massive source of chakra, there was another chakra aura that he was very familiar with—Minato Namikaze.

In this way, the owner of the massive chakra source next to Minato Namikaze became clear—Kushina Uzumaki.

Izumi Nen raised an eyebrow slightly, never expecting to encounter Minato Namikaze and Kushina Uzumaki today.

Now that he had encountered it, he naturally wouldn't let go of this opportunity to observe the Nine-Tails Jinchuriki and the sealing techniques on his body.

He remembered that the seal on Kushina's body was the Four Symbols Seal.

The Bagua Seal, which Minato later improved and could absorb the chakra of the Tailed Beasts and convert it into his own chakra, was also an improvement on the combination of the Four Symbols Seal.

Although he could not directly see through the specific operation of the Four Symbols seal on the Jinchūriki, he could deduce part of the operating route through blood flow and the transmission of nerve electrical signals.

With a turn of his foot, Izumi Nen headed towards where Minato Namikaze and Kushina Uzumaki were.

A few minutes later, Izumi Nen successfully "bumped into" Minato and Kushina.

"Oh, it's Izumi-kun! Long time no see!"

Minato Namikaze immediately recognized Izumi Nen, who was strolling around in the crowd, and then pulled Kushina Uzumaki over to him.

"Brother Minato, it's been a long time." Izumi Nen greeted Minato Namikaze first, then looked at Kushina Uzumaki standing to the side, paused for a moment, and then said with a look of realization, "Could this be Brother Minato's...?"

Upon hearing this, Minato blushed and quickly interrupted, "This is Kushina Uzumaki, my... good friend."

Seeing Minato Namikaze's awkward expression, Izumi Nen gave him an "I understand" smile, and then politely greeted Kushina Uzumaki, "My name is Izumi Nen, please take care of me, Kushina-neechan."

After saying that, a faint purple light flashed in his eyes.

Kushina was already unhappy that someone had disturbed her and Minato's leisure time, but she didn't show it on her face and responded to Izumi Nen with a smile.

However, just as Izumi Nen activated the Purple Eye at its lowest power, Kushina still noticed something amiss.

She looked at Izumi Nen's faintly purplish eyes with a puzzled expression, and asked curiously, "Izumi-kun, your eyes...?"

"It's a small research project I've been doing with Orochimaru-sensei recently. As for the specifics, I need to keep it a secret." Izumi Nen remained calm and composed.

Minato Namikaze, who was standing to the side, was also drawn to the unusual look in Izumi Nen's eyes. He had heard the Third Hokage mention it, but he didn't know the specifics.

The three of them chatted briefly before parting ways.

However, just as he was leaving, the dark purple light in Izumi Nen's eyes suddenly intensified, and in the next instant, his spiritual will suddenly entered a dark and void space, where he saw a huge fox with orange fur in the darkness.

Nine tails!
