Both time-traveled characters ended up as villainous henchmen.

"By the way, aren't you a student at the True Spiritual Arts Academy? You don't seem to fit the role of a villainous henchman at all."

One of them, He Nian, put his arm around the shoulder of Death He Nian and said in a teasing tone.

"Did he really switch allegiance to Aizen later?"

After a series of therapeutic talks by He Nian, Death God He Nian completely recovered from his manic state. Now, thinking back, he felt a little embarrassed.

Upon first encountering Aizen, he was thrown into a state of mental turmoil, and then he got stuck in a rut, unable to process things properly, which led to many embarrassing situations.

Even if the Black Mist Space hadn't come, he would have figured it out himself after a while, but the current situation is even better.

Death God He Nian awkwardly scratched his head and guessed:

"Of course, you can't tell what kind of villain he is now. But once you wait until the Traveler's Triumph arc, when the main characters enter Soul Society, I, a student of the Shinigami Academy, will probably become the villain who stops the main characters."

Death God He Nian was very open-minded and didn't care much about the villainous grunt role that He Nian was concerned about.

As for joining Aizen, what a joke! He has an iron will and would never willingly be subservient to anyone!

"Don't panic, everyone. I'll just use my Bankai next time to take you all flying!"

Death God He Nian made a bold statement to the rest of the crowd.

"Forget it, let's talk after you've released your initial release."

He Nian didn't quite believe the rest. Putting aside the fact that He Nian, the Shinigami, couldn't even achieve Shikai yet, even if he did manage to master Bankai after returning, his Zanpakuto couldn't appear in other worlds.

It's highly likely that each person will have to go back and put in a lot of effort to understand and transform things according to the rules of their own world, and there's no guarantee they'll succeed.

"You'd be better off focusing on mastering the four areas of 'slashing fist' and 'walking ghost'."

Pirate He Nian suggested that he currently has a great need for swordsmanship, as the martial arts and sword techniques he provided are not very useful in the world of One Piece.

"That works too." Death God He Nian readily agreed, but then remembered something else and said to Hokage He Nian, "Why don't you go and get a Sharingan and put it in, and study genjutsu in more depth? That way, I'll have a better chance of defeating Aizen."

Upon hearing this, Hokage He Nian nodded: "That's possible, but with my current strength, I probably can't get a really good Sharingan."

He Nian, the Naruto, originally didn't want to go down the path of creating various genetically synthesized bio-engineered monsters, but considering that the Sharingan is a plug-and-play device, it seems like having a few spares wouldn't be a bad idea.

With the self-healing power brought by his Yin Release technique, he can directly hot-swap with his skin even without medical ninjutsu.

In that case, we can also work on Hashirama cells and then compare and study how the Sharingan and Hashirama cells fuse, which might provide some inspiration for his Yin-Yang Release fusion.

The more Naruto He Nian thought about it, the more reasonable it seemed. So, after briefly explaining it to the others, he was the first to log off.

Seeing this, the others didn't linger. After chatting for a while, they waved goodbye with their respective goals in mind.

As the black mist space fluctuated again, the dense black mist surged towards everyone in the space once more, and the next moment, a familiar sense of spatial traversal came.

When they opened their eyes again, everyone had returned to their own world.

One Piece world.

On the vast, boundless sea, a pirate ship flying a blindfolded skull and crossbones flag sails steadily under the starry night.

On the bow deck, He Nian slowly rose from his cross-legged meditation position.

He gazed at the calm sea reflecting the starry night sky under the clear night sky, and his heart was filled with peace.

"It's like a timely help coming to my door. I was worried about how to improve my cultivation technique, but now..."

He Nian's face, bathed in moonlight, was filled with a confident smile.

The Taoist scriptures that He Nian shared this time perfectly filled in the gaps in his understanding of meditation and visualization techniques, which he hadn't been very familiar with before.

He had a premonition that by dawn, he would be able to successfully master the new mental cultivation technique that he had been studying for nearly a month!

Since sharing He Nian's special self-healing ability with Demon Slayer last time, He Nian has noticed some changes in his body.

Humans in the One Piece world have a strong advantage in physical strength and injury recovery. However, He Nian's self-healing ability does not recover by consuming his own life force, but by absorbing the life force of others to replenish himself, thereby gaining an abnormally high-speed regeneration ability. The two self-healing abilities are fundamentally different.

When these two different recovery and self-healing abilities are combined and transformed by the rules of the One Piece world, He Nian directly enters a realm similar to the return of life.

In the world of One Piece, the ability to return life is achieved by infusing consciousness into the body, thereby gaining control over various parts of the body. This allows the user to quickly digest food, change their body shape, and enhance their combat abilities.

But He Nian's life was returned in a different way.

Besides the basic functions of rapidly digesting food, changing body shape, and increasing combat power, he can also quickly heal his injuries through life return, at the cost of the food he had previously eaten and his own stamina.

Moreover, unlike Luffy and his crew in the original work who need to eat a large amount of food before activating this ability, He Nian can select a portion of food during his daily meals for this conversion and storage, and then consume it when needed.

Of course, due to body size and the limits of physical endurance, the amount stored will not be too large.

He Nian tested it, and his current storage limit can probably support him to recover from severe injuries about three times. If the injuries are more serious or he is on the verge of death, the number of times and the degree of recovery will be reduced.

Furthermore, he is able to achieve a more subtle level of control over his body through consciousness.

In other words, He Nian has a closer connection between consciousness and body.

It was this discovery that led He Nian to abandon his attempt to emulate the energy circulation techniques of the Naruto series, and he considered another direction for cultivation.

Cultivating both body and spirit, uniting the soul and flesh, and achieving harmony between form and spirit.

Having experienced the powerful awakening earlier, He Nian has realized that the connection between individual will and body in the One Piece world is far stronger than in the Naruto world.

Furthermore, the return of his life provided him with the foundation for the unity of body and soul.

He didn't seem to need to bother with any domineering qi cultivation techniques; he only needed to vigorously train his body and temper his spirit, and his domineering aura would continue to rise.

If he can take a further step in the unity of spirit and body, and the harmony of form and spirit, then his future body tempering will be the same as spirit tempering, and spirit tempering will be the same as body tempering. There will be no need to use those complicated and fancy methods.

Pure, it seems to fit the tone of the One Piece world even better.

Following this line of thought, He Nian decisively abandoned the creation of meridian-based cultivation techniques. As for body tempering, the simple weight-bearing training was already quite effective, so he focused on mental cultivation techniques.

After leaving the island of Irit, he once again embarked on a journey of wandering at sea.

After more than a month of exposure to wind, sun, and turbulent waves, he has gradually grasped the direction of creating spiritual mystic arts, but due to a lack of experience, he has been unable to move on to the next step.

Now, the Black Mist Space has filled that gap for him.

He Nian sat down cross-legged again, bathed in the cool moonlight under the starry night, gazing at the mirror-like calm sea, touching the illusory boundary between the mirrored moon and the real moon.

In an instant, a cool and calm aura quietly spread from He Nian and quickly spread throughout the entire pirate ship.

Tonight, the wind and waves are calm.
