"Indeed, it is the Devil puppets I personally crafted..."
"It seems I can't afford to slack off even for a moment..."
Facing the tight encirclement by Tyrant, Toshogun, and Michael in front of him, Yu's lips revealed a hint of satisfaction.
Yes, he was currently using the Parasitic Threads Manipulation to spar with these three Devil Puppets, simulating the effects of practical combat training.
Rainfall Spear!!
Muttering to himself, Yu's movements did not pause at all. The power of Thread Fruit erupted within him. He extended his hand forward, and countless threads shot out from his body like sharp arrows, attacking the three Devil Puppets in front of him.
"Bang! Bang! Bang!!"
The sounds of countless impacts and explosions echoed. The lines thrown out at high speed, like bullets, resembled a sudden downpour, riddling everything in front of him with holes.
The enormous Iron Sand triangular cones manipulated by Michael using Magnet Release Chakra were finally completely scattered, transforming into numerous fine and toxic Iron Sand particles that floated back into the air.
Barrier Arc!!
At the same time, Michael's index and middle fingers intertwined in front of him, activating the power of the Barrier Fruit.
Instantly, he created a massive and transparent Protective Barrier resembling a fortress, arcing in front of him. It intercepted the countless lines that were assaulting thzm from all directions like a torrential downpour, shielding himself, Tyrant, and Toshogun.
Compared to a regular Protective Barrier, this arched shield not only had a larger surface area but also, with its curved structure, effectively defended against attacks from all directions - front, back, left, and right.
After three years of training, Yu's Thread Fruit ability had reached the pinnacle of the Seven Warlords' realm, nearly stepping into the level of an Admiral.
Similarly, the Devil Law power within Michael and the other Devil Puppets had undergone qualitative and quantitative changes, becoming even more formidable.
"Alright, that's enough..."
"Let's call it a day for today's training."
Seeing the three Devil Puppets in front of him withstand his attacks unscathed, Yu nodded in satisfaction.
Dispersing the Chakra maintaining the Ninjutsu barrier around, he looked at the chaotic gorge before him. Yu reached down and picked up a black Ninja uniform lying on the ground, putting it on.
Three years had passed, during which Yu not only fully consolidated his Kage-level strength but also enhanced the purity and strength of his Chakra and Thread Fruit abilities, showing significant progress compared to the past.
His pale, moon-like disheveled hair had grown a bit longer, and his sharp and handsome facial features had matured. At the age of twelve, Yu's height had reached one meter and sixty-six centimeters, surpassing Naruto and Sasuke of the same age in the anime by about half a head.

"Observation Haki and Armament Haki have also improved significantly..."
"Unfortunately, it's still not quite enough, couldn't break through to the next stage."
After dressing, feeling the considerable enhancement in himself, but still unable to break through the bottleneck to enter the next stage of Observation Haki and Armament Haki, Yu couldn't help but feel a bit dissatisfied.
According to what the Devil said, entering the second stage of Observation Haki not only enhances sensory abilities but also significantly expands the sensory range. It can even enable communication and telepathy with others. As for the second stage of Armament Haki, it can fully cover the entire body for overall reinforcement. This way, Yu wouldn't need to worry too much about the physical strain after activating Shunko.
"Forget it, no use dwelling on it. Rome wasn't built in a day."
"Today is an important celebration in Konoha; those guys from Hidden Cloud should be arriving soon."
Understanding that training requires a gradual approach, after tidying up his emotions, Yu's gaze fell upon the motionless Third Raikage human puppet standing nearby.
Air Door!!
As Yu's thoughts shifted, the Third Raikage human puppet next to him instantly walked over. The fan-like large hand pushed through the seemingly empty air in front of Yu, creating a circular gateway in the once calm atmosphere.
Though the scene inside the space appeared identical to the real world where Yu currently resided, it exhibited a strange, inky green hue, as if leading to an unknown abyss.
Indeed, the ability bestowed upon the Third Raikage human puppet by the Devil was none other than the Door Door Fruit ability, belonging to Bruno, one of the members of CP9 in "One Piece."
Simultaneously, the Door Door Fruit ability stood out as one of the most potent but underutilized spatial Devil Fruit powers in "One Piece," without rival.
Air, flames, the ground, walls, and even the human body, no matter how solid or lacking in physical form, the Door Door Fruit could create doors.
The essence of the Door Door Fruit lay in its ability to create doors of different types, sizes, and shapes according to the user's intention, such as sliding doors, swinging doors, or even revolving doors. The user could even transform themselves into a door.
The key feature of the Door Door Fruit was its freedom of movement within space. By opening a door, it could create a space with an inky green hue. Besides the user, anyone else could enter this distinct space for spatial movement.
The alternate space created by the Door Door Fruit can serve not only as an emergency refuge but also as a means to evade enemy attacks during battles. After closing the created door, the opened portion returns to its original state, leaving no traces behind.
If Bruno from "One Piece" were using the Door Door Fruit's ability, reaching the target location would require moving within the alternate space to the designated spot before creating another gate.
However, given Yu's current development, which is close to the level of an Admiral, as long as the target location has been seen and recorded by Kaio, he can directly open the door to reach his destination.
In other words, with the Door Door Fruit's ability, Yu can seamlessly transition from a life-and-death battle with enemies one moment to a leisurely stroll on a country road the next.
Even when compared to the world's most formidable Space-Time abilities—such as Uchiha Obito's Kamui, Otsutsuki Kaguya's Yomotsu Hirasaka, and Minato Namikaze and Senju Tobirama's Flying Thunder God Jutsu—the Door Door Fruit's ability stands equal and shows no signs of inferiority.
Given the Third Raikage's puppet, with its ability to freely traverse alternate spaces using the Door Door Fruit, Yu aptly named it "Kaio."
Swoosh!
Gazing at the circular door Kaio opened in the air, Yu hesitated for no moment and stepped right in.
Upon entering the mysterious inky green alternate space, simultaneously, at the bustling center of Konoha, on the rooftop of a building, the once calm air abruptly opened a circular door.
"It's really convenient..."
"If Kaio's ability had appeared a few years earlier, perhaps the Great Ninja War might have ended sooner."
The next moment, when the figures of Yu and Kaio reappeared, they had traversed countless distances and stood on the rooftop at the bustling center of Konoha.
Gazing at the crowded streets below, Yu couldn't help but sigh. The air door behind him closed completely, and everything returned to calm.
