Both time-traveled characters ended up as villainous henchmen.

The rest of the process went smoothly. Although Orochimaru appeared next to the Third Hokage, nothing unexpected happened.

As Izumi Nen had expected, the final match was a duel between him and Kakashi.

The result was predictable: after a thrilling battle, Izumi Nen emerged victorious and earned the title of Chunin.

Kakashi also earned Chunin status due to his exceptional skills displayed in battle.

The Chunin Exams came to a happy end.

After obtaining his Chunin qualification, Izumi Nen's life returned to its previous rhythm.

His daily training was followed by research into Yin Release Eye Techniques and Sealing Techniques.

Because Orochimaru was still by his side, Orochimaru did not conduct extensive research on the White Zetsu in the scroll. Instead, he guided the chakra within the White Zetsu through a sealing technique and then used his own Sage Art Yin-Yang Release chakra to simulate it, attempting to analyze the White Zetsu's chakra abilities and thereby obtain the corresponding abilities related to the Divine Tree.

Unfortunately, progress is slow.

He also took the time to ask Shiori Yamanaka about her feelings after performing the Mind Transfer Technique.

"It was like slamming into a huge wall; I passed out before I could even see anything clearly."

This is how Shiori Yamanaka describes it.

Based on just this one sentence, Izumi Nen couldn't figure out the specific reason. Could it be that his Purple Nether Eyes could form a mental protective barrier?

[At this point, I hope readers will remember our domain name: 20 ...

But reason told him it was impossible; the immature bloodline of the Purple Nether Eye was far from reaching that level.

As for Danzo, Izumi Nen told Orochimaru about his speculations regarding Kenji Uchiha's abnormality. Orochimaru told Izumi Nen not to worry, as he and the Third Hokage would handle it.

As expected, Izumi Nen was not disturbed again afterward, and the problem with Uchiha Kenji was also properly resolved.

The peaceful days continued until the night before Orochimaru was to take him away from the village on a mission.

The black mist space descended once more.

When that feeling of being isolated from the world came over him, Izumi Nen's thoughts instantly became clear. He seemed to have guessed where that special protective shield on his soul came from.

……

Black fog space.

Hokage He Nian did not immediately rush into the gathering of people, but stayed where he was, feeling the powerful sense of security that came from being enveloped by the black mist.

He seemed to have discovered another use for the black fog space.

Protection of the soul.

However, he was still unsure whether this kind of soul protection was something everyone possessed, or whether it needed to be manifested through similar soul abilities within their respective worlds.

Just as Hokage He Nian was in a daze, someone quietly circled around from behind and gently placed their palm on Hokage He Nian's head.

"Holy shit!" "Holy shit!"

After He Nian exclaimed in surprise, it was immediately followed by He Nian's angry shout.

One person exclaimed in surprise because He Nian, the Naruto character, had actually created a Yin-Yang seal in the Naruto world.

The Hokage, He Nian, roared angrily because he had been patted on the head.

However, the two did not play around for long before they were drawn to the lively scene where a crowd had gathered.

Upon closer inspection, they discovered that it was the pirate He Nian demonstrating the martial arts technique he had independently developed to Pika Nian and Yagu Nian.

However, Pikachu and Agu were clearly not interested in the pirate He Nian's techniques; they simply did a good job of being the straight man.

Pirate He Nian was just worried about having no one to brag to when he saw He Nian and Hokage He Nian walking towards him.

"You've come at the right time. Would you like to hear my legend...?"

Pirate He Nian was speaking when Naruto He Nian ambushed him, clapping his hands and completing the sharing of power and memories.

"Why be so formal between us? We're all family."

Although the memories shared by Naruto and He Nian do not provide details about how He Nian, the pirate, created the two techniques.

But once the power is shared, that's about it.

He Nian, being quite accommodating, clapped his hands and then, like Pika Nian and Yagu Nian, sat down next to the pirate He Nian, pretending to listen patiently.

After all this commotion, He Nian, the pirate, lost the desire to recount his experiences and instead shared the relevant memories with everyone.

The three people and two beasts then started chatting on the spot.

Soon, with a ripple in the black mist space, Death God He Nian slowly emerged from the black mist.

Hokage He Nian was as quick as ever, and was the first to complete the sharing of power and memories with Death God He Nian.

"What? Didn't you boast last time that you'd use your Bankai to carry us through the world, and now you're stuck in your Shikai?"

After briefly reviewing He Nian's memories, Naruto exclaimed in surprise.

Death God He Nian shrugged, sat down next to Pirate He Nian, and then began to explain:

"There's no other way. To achieve Shikai, I need to inscribe my soul essence into Asauchi. But after sharing my power with you all, I suddenly don't know what our soul essence is anymore."

Death God He Nian suddenly gained immense power, and the essence of his soul became even more diverse and complex.

As a result, when practicing sword Zen, he was unsure which quality to infuse into his aspatsu.

Choosing just one of them felt somewhat inappropriate, and if he wanted to inject all the traits at once, the shallow strike couldn't handle that many, which led him to quit the sword Zen.

After a while, he got stuck here.

Rather than saying he was stuck, it would be more accurate to say he suffered from decision paralysis, while his greed for controlling all the world's power had not completely faded.

After much thought, he decided to first visit the Black Mist Space and ask his counterparts in other worlds for advice.

After all, he still has plenty of time and there's no need for him to rush to improve his strength.

After figuring things out in the Black Mist Space, he put Aizen's matter out of his mind for the time being, and subsequent events proved that he had been overthinking things.

Aizen never paid any attention to him.

Upon hearing He Nian's confusion, the others fell into deep thought, except for the pirate He Nian, whose eyes lit up and voiced his guess:

"Do you think our true essence might actually be this dark, misty space...?"

As he spoke, he pointed to the endless black fog all around.

Upon hearing this, Hokage He Nian immediately recalled what he had been thinking about after entering the Black Mist Space.

"Will the Black Mist Space also provide us with soul protection?"

One of them, He Nian, exclaimed in surprise, but he quickly remembered that when he first entered the Black Mist Space, he was influenced by Xia He's seductive arts, and it was the Black Mist Space that helped him break free from its control.

In a sense, it is indeed a manifestation of soul protection.

"I think the soul protection provided by the Black Mist Space belongs to the latter category. It will manifest differently depending on the soul abilities of different worlds, but the strength of the protection will not be significantly different."

He Nian, the pirate, responded immediately. He realized that the black mist space power that descended into the pirate world with the help of Conqueror's Haki was the black mist space protecting his soul. It was also because of this special protective power that he was able to divide the desires of Devil Fruits.

"So, is there any special connection between protecting my soul and how I should perform my Shikai?"

Seeing that the topic had gone astray, Death God He Nian immediately spoke up to steer it back on track.

"I don't know, but the fact that you weren't noticed by Aizen might be a manifestation of the protective power of the Black Mist Space." Pirate He Nian shook his head and then offered another hypothesis.

"The Black Mist Space is very likely the true essence of our souls, but if you want to successfully release your soul, it's best not to guide the power of the Black Mist Space into your soul first."

It's highly likely that the world's will and rules in other worlds do not welcome the entry of special forces like the Black Mist Space.
