A gentle breeze blew by, causing the navy coats worn by Senga and Zephyr to flutter loudly.
Zephyr's tense body suddenly relaxed. He looked at Senga opposite him and said with a smile,
"Senga, your strength has far exceeded your teacher's expectations. To be honest, the position of Marine Admiral is a bit of a waste for you."
Senga hung his arms at his waist and responded with a smile.
"On the contrary, I think that Professor Zephyr is in a state where he could easily serve as Marine Admiral again."
After saying that, the two of them laughed at the same time, as if they hadn't been the ones exchanging punches so wildly just now.
After laughing for a while, Zephyr shook his neck, grabbed his navy coat and threw it away, then began to slowly unbutton his shirt underneath.
Zephyr said as he unbuttoned his shirt.
"I've had enough of that seat. I'll leave it for you young people. Now, all I want is for you to show your true abilities, Senga."
After unbuttoning the last button, Zephyr took off his shirt, revealing a well-defined physique that exuded power.
Seeing Zephyr's actions, Senga also threw off his navy coat and unbuttoned his shirt just like Zephyr. He knew that Zephyr was about to use his full strength.
Once ready, Zephyr let out a loud shout, and his muscles began to swell at a visible speed, with even the bulging blood vessels becoming visible.
Gradually, dense black fur grew on Zephyr's body, covering it completely, and a pair of gray horns grew on his head, with black patterns on the horns similar to those of Devil Fruit.
A thick layer of bone armor had appeared on his shoulders, shimmering with a milky white luster in the sunlight.
This is the power of the Ox-King Fruit; Zephyr has now entered Zoan transformation state.
Two streams of white gas shot out from Zephyr's nose, which had become almost like a bull's. He grinned at Senga with a black face, revealing two rows of white teeth.
Zephyr said in an extremely deep voice,
"Sorry to keep you waiting, Senga. So this is the effect of your Ox-King Fruit. How does it look?"
Senga raised an eyebrow. To be honest, Zephyr's current posture definitely looked incredibly Haki, but his face was just... indescribable.
Imagine what it would be like if a normal person's face suddenly turned black and grew a cow's nose; it would definitely not be good-looking.
However, out of consideration for her status as a student, Senga reluctantly gave Zephyr a thumbs-up and praised him.
"He looks really handsome!"
"Nonsense!"
"?"
A big question mark appeared above Senga's head, wondering if there was something wrong with her assessment.
Zephyr pouted and said irritably,
"I've looked in the mirror before, what does this cow-face have to do with being handsome? You better be honest with your teacher!"
"..."
Senga was inwardly fuming. She should have just told the truth; she had really shot herself in the foot.
Feeling somewhat aggrieved, Senga didn't waste any words and directly used the power of the Asura Fruit, expanding his size to be similar to that of Zephyr.
Zephyr nodded after seeing this and said,
"So this is the power of that Asura Fruit, isn't it? Not bad. Come on! Let me see what kind of boost this fruit can give you!"
As soon as he finished speaking, Zephyr stomped his large foot heavily on the ground, and a terrifying crack instantly spread towards Senga's location.
Of course, this kind of attack had no effect on Senga, who could fly. He used the power of the Heavenly Path to fly directly into the air, and his four arms behind him transformed into four cannons, firing wave after wave of lasers at Zephyr on the ground.
Faced with this dense laser attack, Zephyr frowned, because this move reminded him of a certain ape.
What he didn't know was that Kaido was thinking exactly the same thing as him when facing Senga's laser.
Zephyr pressed his arms to the ground, and a thick earthen wall suddenly appeared in front of him, covered with a spiral black pattern, just like the one on his bull horns.
The laser struck the earthen wall, raising a cloud of yellow dust. Zephyr, standing behind the wall, looked serious; he sensed that the wall was about to collapse.
He was once again impressed by Senga's skill; after all, this was no ordinary earthen wall.
Controlling earth element is an inherent effect of the Mythical Zoan Ox-King Fruit, and the earth element he controls is enhanced, with a hardness far exceeding that of steel.
Even with such defense, Senga's attack still couldn't be stopped, which shows just how powerful Senga had become.
The laser beams from the sky continued to bombard the earthen wall summoned by Zephyr. Finally, the earthen wall could no longer hold on and collapsed into a pile of Kitsuchi that splattered everywhere.
At the moment the earthen wall collapsed, a fluid composed of Kitsuchi spread from the ground along Zephyr's arms and throughout his body, then hardened to form a layer of Kitsuchi armor.
Zephyr pulled his arms off the ground and crossed them to protect his head, using his body to receive the subsequent laser attack. Dense lasers bombarded Zephyr and the ground beside him, raising a thick cloud of smoke.
After a long while, the smoke dissipated, revealing Zephyr inside, still maintaining a defensive posture.
You can see that Zephyr's Kitsuchi armor has crumbled into pieces and slid off, leaving behind dazzling specks of light on his body.
Senga landed on the ground and looked at the points of light on Zephyr's body. His lips twitched involuntarily. Why did the scene before him seem so familiar?
Did I end up doing what Kizaru was supposed to do? Honestly, he had no intention of killing Zephyr!
Senga couldn't help but start to worry about Zephyr's current physical condition, wondering if she should hurry up and give her teacher an Ishichikahime.
Fortunately, Zephyr didn't keep Senga worried for long. He slowly lowered his arms and then suddenly bent over and lay on all fours.
His body began to swell again, and within moments he transformed into a gigantic black bull with a thick layer of bone armor on his back.
Clearly, Zephyr had fully entered the Zoan transformation form of the Ox-King Fruit. He was aware of the gap in strength between himself and Senga, so he didn't want to continue like this. He prepared to use his strongest attack to end the battle.
The patterned bull horns on Zephyr's head had now turned pure black, a result of him injecting all his Armament Haki into them.
At this moment, Black Arm Zephyr has completed its transformation into Black Bull Zephyr.
Several plumes of steaming hot air shot out from his nostrils again. Zephyr locked onto Senga with his huge bull eyes, stomped one hoof on the ground a few times, and then his whole body transformed into a black Inazuma, rushing towards Senga.
Senga understood Zephyr's meaning. Destructive Armament gleaming with a purplish-black light appeared on his right hand, and he unleashed a powerful attack on Zephyr, who was coming towards him.
A deafening roar resounded throughout the entire Marine Headquarters.
Sengoku was sipping hot tea in his office, was startled by the sudden loud noise, causing his hand to tremble and spill scalding tea all over himself.
Sengoku looked down at the large water stain on his pants, and after a while he came to his senses. He rushed out of the headquarters building and looked in the direction from which the sound came.
What the Sengoku period saw was only a huge mushroom cloud.
