Synthesis Ninja system

Shizune was still in shock, while Shiro quickly ran off into the distance, diverting Manda's attention.

"Good! Since you want to die, don't blame me for what's coming!" 

"Orochimaru, when did you become so weak that you needed me to handle a kid? But even if it's just a kid, I won't accept less than a hundred sacrifices!"

"Fine! Kill him quickly!" Orochimaru growled through gritted teeth.

Seeing Manda move, Shiro frowned. 

Although Orochimaru was no longer able to fight, Manda's strength was still on par with half a Kage level, not to be underestimated!

"Earth Style! Mud Wall!"

Suddenly, the ground beneath Manda turned into a swamp, and Manda's massive body sank into it.

However, Manda was just too big. Shiro couldn't create a pit deep enough to fully trap the enormous snake. He could only rely on the mud to limit Manda's movements!

"Damn it! Is this kid really a kid? How can he use such powerful ninjutsu!" Manda roared, glaring at Orochimaru.

"As long as you kill this brat, I'll give you 200 sacrifices!"

"You better keep your word!" Manda's cold voice carried a hint of joy. "I'll devour this brat first!"

Manda twisted its body with astonishing speed, surrounding Shiro in an instant. With a sinister grin, it lunged at him with its massive jaws!

"Ninjutsu! Multi-Size Technique!"

*Boom!* 

A puff of smoke erupted, and Shiro's body instantly enlarged, growing to several times his original size, towering over the battlefield like a mountain. At this moment, Shiro was even taller than Manda! With both hands, he grabbed Manda's upper and lower jaws, holding back the beast's gaping maw with sheer force.

"Orochimaru! Who is this kid?"

"I want to know that myself!"

Summoning all his strength, Shiro hurled Manda away! 

However, right after tossing the giant snake, Shiro realized something was wrong. Although the Multi-Size Technique always consumed a lot of chakra, this time, the chakra drain was far beyond normal!

"It seems that the Akimichi clan must have special ways to manage their chakra when using the Multi-Size Technique, or else they'd be completely drained after just a few steps!" 

Shiro scoffed. Now wasn't the time to hesitate—he had to take down Orochimaru before his chakra ran out completely!

"Hmm, if I get over there, Granny Tsunade won't be in danger anymore."

With that thought, Shiro grinned and leaped high into the air, aiming a powerful punch at Manda!

With the Multi-Size Technique, Shiro's weight was astronomical. Adding to that the force of his jump and the impact of his punch, the ground shook violently the moment he landed! A shockwave blasted out, uprooting the surrounding trees, and a massive crater appeared as if struck by a meteor!

Fortunately, he was far enough away from Tsunade and the others; otherwise, the shockwave alone would have been enough to cause serious harm.

Manda narrowly avoided the direct hit, but with its body so close to the ground, the vibrations from the impact traveled through its body.

"Damn you, Orochimaru! I'll remember this grudge!" Manda roared in frustration before disappearing in a cloud of smoke.

Shiro, however, was in bad shape. He bent over, hands on his knees, gasping for air, his body trembling. What he thought would be an easy strike had drained all his chakra in an instant. Still, the power was terrifying! No wonder the Akimichi clan rarely used other ninjutsu after using the Multi-Size Technique—they probably couldn't afford to. 

With a puff of smoke, Shiro returned to his original size. His chakra was almost completely depleted; he could barely move. He lay on the ground in the shape of a star.

"Hehe, didn't expect to see you in this state," came Orochimaru's cold laugh as he walked over to Shiro, his eyes gleaming with desire.

"This body of yours is about to be mine!"

Orochimaru's neck stretched out as he lowered his head toward Shiro's face. But just as Shiro's face showed fear, a faint smile appeared on his lips.

"Orochimaru, have you forgotten about Uchiha Itachi?"

Orochimaru paused for a moment, then grinned wickedly. "I don't know how you know about that, but it's too late now! You'll soon be part of me!"

Orochimaru lunged at Shiro to bite him, but suddenly, Shiro turned into Uchiha Itachi!

Startled, Orochimaru jumped back several steps. 

"Impossible! No, it's a genjutsu! Damn kid!" Orochimaru roared, turning his gaze back to Shiro. But the Shiro that had been lying on the ground was gone, replaced by countless Uchiha Itachis, all staring down at Orochimaru with their Sharingan.

In reality, Shiro was still lying on the ground, his chakra too depleted to cast any ninjutsu. But fortunately, the day before, he had set up a pre-cast genjutsu on Orochimaru. All it needed was a glimpse of the Sharingan to activate, trapping Orochimaru in an illusion where he saw multiple Itachis!

With Orochimaru trapped, Shiro had just enough time to activate the Creation Rebirth technique. The technique only required a tiny bit of chakra, and after about thirty seconds of resting, Shiro had just enough to use it!

The Creation Rebirth technique allowed him to access his stored chakra reserves. Although Shiro hadn't stored much chakra, it was better than nothing. Black marks disappeared from his forehead, replaced by dark lines that spread across his face. With the extra chakra, Shiro was finally able to stand again.

But before long, Kabuto appeared, clutching a wound and rushing toward them. 

Upon seeing Orochimaru, Kabuto frowned.

"Genjutsu?"

Kabuto immediately lowered his gaze, careful not to meet Shiro's eyes, and quickly threw a kunai at Orochimaru.

The sharp pain snapped Orochimaru out of the illusion.

"Orochimaru-sama, Jiraiya is coming! We have to go now!" 

Orochimaru shot Shiro a venomous look, full of unwillingness.

"Let's go!"

With Orochimaru's escape, the mission was successfully completed! However, just as Shiro was about to rejoin the others, he stopped. Tsunade's fear of blood was only cured when she treated Naruto Uzumaki. In her current state, it might be impossible for her to recover from it!

With such a major weakness, she could easily be exploited in the future.

Thinking this, Shiro pulled out a kunai and made a cut on his hand, smearing blood over himself.

"What are you doing?" 

Playing dead! I won't get up until you give me a vote!
