Both time-traveled characters ended up as villainous henchmen.

Day two.

Izumi Nen did not continue his training, but instead went out to meet Obito.

Last time, in order to obtain Obito's blood for research purposes, he gave Obito a secret method for mental training.

The secret technique was a small discovery he made while researching the connection between illusion, Yin Release, and the chakra meridian system; it can be considered a kind of self-hypnosis-like auxiliary secret technique.

This secret technique was not only for Obito's benefit, but also for his preparation for the next stage of the experiment.

Now that more than a week has passed, Obito should have made some progress, so it's time to reap the rewards.

On the familiar training ground in the forest, Obito, wearing goggles, arrived as promised.

Izumi Nen was somewhat surprised to see this. This guy wasn't late this time. Last time he asked Obito to come out, he waited for two whole hours.

It seems that the little gadgets he made were very much to Obito's liking.

"Izumi Nen!" Obito was idly picking at the grass on the ground when he saw a familiar figure slowly walking towards him.

"Can't you walk a little faster? Do you know how long I've been waiting for you?"

"have no idea."

Izumi Nen casually interrupted Obito's subsequent complaints, saying, "How's your training going? I'm here to check on your progress."

If it doesn't work, you'd better stop training. After all, not every ninja can endure this kind of pain.

"How could that be? This little bit of pain can't stop my determination to become stronger. Besides, I've already become stronger. The secret technique is very effective."

Obito retorted with great confidence, his face full of self-assurance.

Izumi Nen was also able to sense the improvement in the quality of Obito's chakra.

The results seem to be quite good.

"In that case..." Izumi Nen laughed, raised his hand to summon the familiar blood-drawing equipment, and continued to Obito, "Then let's draw blood again."

"Huh! Why?!"

Obito quickly retreated, moving away from Izumi Nen who was holding the syringe, his face clearly showing fear.

Seeing that he could no longer easily fool Obito, Izumi Nen didn't hide anything and revealed the purpose of his blood draw.

"experiment?"

"Yes, an experiment to explore the extent to which spiritual energy affects chakra enhancement."

Since the experimental data is based solely on my own blood, it's inevitable that the results will be inaccurate, which is why I'm asking for your help.

Okay, stop looking so gloomy. After the blood draw, I'll treat you to dinner. How about Ichiraku Ramen?

By the way, let me teach you some dating tips. Just three words are all you need to warm her heart all day.

Izumi Nen deliberately lowered his voice and whispered the last sentence into Obito's ear.

Obito, with a serious expression, nodded and pondered for a moment before agreeing.

Soon, the two who had finished having their blood drawn arrived at Ichiraku Ramen, a famous tourist attraction in Konoha.

"Boss, two bowls of tonkotsu ramen, with extra meat and egg!"

"Okay, no problem."

After ordering, Obito sat down with satisfaction. Then, remembering the last thing Izumi Nen had said to him, he suddenly felt an irresistible urge to eat.

Just as Obito was about to question Izumi Nen beside him, a sunny-looking blond young man walked into Ichiraku Ramen and sat down next to him.

This sudden change made Obito too embarrassed to voice his true feelings.

On the other side, Izumi Nen suddenly became wary after spotting the blond-haired youth.

Minato Namikaze... what a coincidence that we ran into each other? Or...?

Izumi Nen remained calm, showing no sign of panic. Instead, he greeted Namikaze Minato first: "Jonin Minato, you're here for ramen too?"

"Oh, it's Izumi-kun. That's right, this ramen is really good!" Minato Namikaze replied with a smile.

"Of course!" the busy hand-tying uncle replied happily.

Izumi Nen had met Namikaze Minato, of course, when he was with Orochimaru. At the time, the two were only briefly introduced by Orochimaru and did not have much interaction.

Although Izumi Nen was very envious of the Uzumaki clan's sealing techniques mastered by Minato Namikaze.

"This must be Izumi-kun's classmate. He's from the Uchiha clan, so he must be a pretty good ninja." Minato Namikaze changed the subject and looked at Obito Uchiha beside him.

"No, Obito hasn't graduated from the Ninja Academy yet."

Obito was initially in a great mood after hearing Minato Namikaze's praise, but Izumi Nen quickly exposed his true colors.

"Izumi Nen, you bastard..."

"Haha, don't worry, I feel that with Obito's current strength, he should be able to graduate soon."

Minato laughed heartily, his demeanor remaining as approachable as ever.

Obito also laughed smugly.

"Of course, thanks to the secret technique scroll I gave him, Obito has been able to make such progress." Izumi Nen did not hide or cover up, but directly pointed out his recent actions.

"Oh, a secret technique scroll?" Minato Namikaze paused, a hint of surprise flickering in his azure eyes.

"Speaking of which, I was inspired by Lord Orochimaru. I recently had some ideas, so I thought I'd try to make them first, and then take them out to see if there's any room for improvement when Lord Orochimaru comes back."

Izumi Nen spoke eloquently, his words overflowing with admiration for Orochimaru. At the same time, he took out another copy of the secret technique scroll from his pocket and handed it to Namikaze Minato.

"I just happened to run into Jonin Minato today, so I'd like to ask Jonin Minato to take a look and see if my crude ideas are wrong."

After a slight hesitation, Minato Namikaze accepted the scroll handed to him by Izumi Nen.

Obito, standing to the side, stared in disbelief. Just as he was about to ask a question, the old man placed a full bowl of ramen in front of him.

"Please use it."

At that moment, Izumi's ramen was ready.

Seeing this, Minato Namikaze stopped worrying and said simply, "I'll take a look for you when I get back. Let's meet here again tomorrow afternoon, and I'll give you some advice then."

"Then thank you very much, Jonin Minato."

After that, the three of them stopped paying attention to the topic and simply chatted about everyday things. After finishing their ramen, they said goodbye and left.

After leaving the street where Ichiraku Ramen was located, Minato Namikaze quickly used the Body Flicker Technique to head towards the Hokage Building.

Although Izumi Nen did not see where Minato Namikaze went, he already had some guesses in his mind.

Moreover, he never intended to hide the fact that he was drawing blood from the soil for his experiments.

The appearance of his new bloodline limit must have a reason, and this is a good opportunity to reveal some of it.

……

Hokage Building.

"That is the reason why Izumi Nen extracted Obito Uchiha's blood."

Minato Namikaze respectfully reported to Hiruzen Sarutobi.

"Are we doing an experiment...?"

Hiruzen Sarutobi looked at Izumi Nen's ideas and speculations in the scroll, and a look of surprise appeared on his face.

Orochimaru really found a good disciple...

The content recorded in the scroll is not particularly profound; it is simply a method that uses the special flow of chakra within the body to induce various illusions, such as accelerated fatigue or a feeling of heaviness in the body, thereby assisting ninjas in their taijutsu training.

It can be considered a variant application of illusion.

What truly surprised Hiruzen Sarutobi was that the chakra flow routes Izumi Nen presented were quite different from typical genjutsu interference routes.

Its flow path overlaps only slightly with that of traditional genjutsu chakra; most of it is a redesign.

In other words, everything recorded in the scroll was developed by Izumi Nen alone!
