Both time-traveled characters ended up as villainous henchmen.

Naruto World.

Izumi Nian opened his eyes, looked at the familiar desk and room, and felt the abundant power within his body. He couldn't help but let out a long breath.

"Thank goodness, it wasn't a dream."

He glanced at the clock on the table; only a fleeting moment had passed since he fell into a deep sleep and entered the black mist space.

"It's a pity I can't cultivate in this space, otherwise this would be an extremely powerful cheat."

After sighing, Izumi Nen got up to wash his face, and then sat cross-legged on the bed.

Besides testing the increased strength he gained from sharing his own abilities, he also wanted to see if the Qi cultivation techniques from his one-person world could work in the Naruto world.

With the help of He Nian's meditation skills, he quickly controlled his emotions and adjusted his state to its best.

First, he tried refining his chakra and found that his current chakra was far superior to his previous chakra in both quality and quantity.

Chakra is refined and synthesized from the physical and mental energy of a ninja. After sharing the power of the two worlds, Izumi Nen experienced significant growth in both his physical and mental abilities, and the change in the quality of his chakra was also evident.

Moreover, he also sensed that his own chakra seemed to be undergoing some kind of special change, but he had not yet found a way to bring out these changes.

"What He Nian, the pirate, said is also correct. The shared power will undergo new changes after being transformed by the world's rules!"

The changes in my chakra now should be a manifestation of chakra nature, but I don't know what attribute it is. Looks like I need to buy some chakra test strips.

Izumi Nen murmured to himself, suddenly filled with even greater anticipation for his future ninja career.

After calming the surging chakra within him, he began the main event of the night: an experiment with the One-Man World Qi Refining Technique.

Although the Taoist sect from which He Nian came has declined, its lineage is authentic and not a side sect.

The practice he uses is a Qi-refining technique called "Yuan Shui Jue," which is neutral and peaceful in nature, making it most suitable for disciples to build a foundation.

Although it's not a famous technique in one's own world, for Izumi Nen at the moment, simple and basic is the most suitable.

After reviewing the instructions in his memory three or four times and confirming that there were no more problems, Izumi Nen slowly began to try the simplest breathing exercises.

For his first attempt, he did not follow the entire recipe exactly. Instead, he carefully selected the parts of the exercise that only involved physical movements and began to experiment with them.

He knew very well that the human anatomy in the Naruto world was completely different from that in the One Piece world, and directly applying it would likely cause problems.

He Nian, the pirate, didn't care about practicing blindly because he had no sense of Qi and no energy-based cultivation system.

But he is different. Chakra and natural energy do exist in the Naruto world, and absorbing natural energy is extremely dangerous. If you are not careful, you may be petrified and die.

When it comes to your own life, you can never be too careful.

As time passed, Izumi Nen continued to breathe slowly and deliberately, and he did not feel anything unusual in his body. He also did not sense any natural energy around him, so he gradually relaxed and began to try to cultivate more deeply.

Following the instructions of the cultivation method, he silently sensed the presence of the primordial Qi within his body.

In the Naruto world, this isn't the case; only chakra matters. But Izumi Nen did as instructed, because he was afraid that rashly using the Qi Refining Technique to activate chakra would bring danger.

Time passed second by second, and Izumi Nen thought he would be like the pirate He Nen, completely unable to sense the existence of his own innate Qi.

But just as he was about to give up and prepare to try to use the Qi Refining Technique to activate chakra in a small area, a special power originating from the depths of his body began to slowly emerge.

This sudden, peculiar power was neither chakra nor any kind of natural energy.

Judging from Izumi Nen's feelings alone, it is actually similar to the innate Qi of the One-Man World!

Could it be that a concept similar to primordial Qi exists in the Naruto world?!

Izumi Nen steadied himself, remaining calm and not disturbing the slowly emerging power within his body.

His intuition told him that waiting patiently was the best approach.

Soon, this power was fully manifested and completely integrated into Izumi Nen's limbs and bones, penetrating deep into every cell.

At the same time, a feeling of complete transformation arises spontaneously.

"Could it be that the power I shared is only now being fully transformed by the world's rules...?"

Izumi Nen broke free of his cultivation state and began to wander around the room, sensing the subtle changes in his body.

Unlike when he first returned from the Black Mist Space, his physical attributes and chakra quality have now seen another significant improvement.

Even the changes in chakra nature that were not very noticeable before have been completely confirmed.

It is water-style chakra, but unlike ordinary water-style chakra, his chakra also possesses a powerful life force and faintly conveys a sense of origin from the source of all waters.

"It's somewhat like the primordial water described in the 'Primordial Water Secret'!"

Izumi Nen couldn't help but exclaim in surprise. If his guess was correct, wouldn't he have directly skipped the ordinary chakra nature transformation and touched the bloodline limit stage of mixing two or more chakra natures?

So, a bloodline ninja has been created?!

"According to the ninja world's understanding, my Water Release technique should be a fusion of Water and Yang Release chakra transformations. The Yang Release is most likely related to the pirates, and that sense of origin..."

Izumi Nen continuously refined his own chakra and transformed it into a special water attribute, silently familiarizing himself with the changes and trying to explore the origin of that sense of origin.

Just then, he seemed to sense a special energy around him.

In an instant, he guessed that this energy was natural energy.

"I can easily sense the natural energy of my surroundings without even meditating or entering a state of tranquility. Does that mean I can enter immortal mode at any time...?"

Izumi Nen muttered to himself, "I'm currently in a constant state of activity. I remember very clearly that when Naruto was training in Sage Mode in the original work, he had to enter a meditative state. To enter it during battle, he could only rely on Shadow Clones."

Even Jiraiya needed the assistance of the two toad sages of Mount Myōboku.

Just as Izumi was recalling the details of cultivating immortal arts from the original work, a sudden change occurred.

The sparse natural energy surrounding his residence spontaneously surged into his body, beyond his control!

Before Izumi could react, it had already completely merged into his body!

Oh no, we're doomed!

Izumi was anxious, but she did not feel any discomfort in her body. On the contrary, she felt a sense of satisfaction and comfort after being nourished by food.

Moreover, once this sense of satisfaction arises, the natural energy around him stops flowing and no longer rushes into his body.

"It absorbs natural energy on its own, without the risk of petrification?!"

Izumi Nen gasped, as if he had discovered a change in himself that was even greater than the nature of his chakra.

He remembered that this innate ability to absorb natural energy was possessed only by the immortals of the three holy lands and the Jugo clan in the original work.

After absorbing natural energy, he showed no signs of losing control, clearly indicating that his physique was that of a holy immortal!

"I have a celestial body! And it's the kind from a sacred celestial realm!"

Now there's hope for immortality!
