Too Late to Mourn, the One Who Rushed to the Battlefield Was...

"I thought I had already adapted to this world. Now I realize just how powerless a person can be."

"Hokage? A hot-blooded series? An inspirational series? Heh."

Uchiha Yuan felt his blood turn icy, unable to sense even a trace of warmth from the outside. The Mangekyō Sharingan spun in his eyes, and the crimson-black lines of its pattern finally bloomed with colors that belonged solely to it.

Walking out of the room, the sounds of slaughter still echoed outside. After so long, Uchiha Yuan finally began forming hand seals himself once more.

"Yin Seal... release."

The Chakra stored over less than two or three days still caused the amount of Chakra in his body to surge. A crystalline blue radiance even glimmered across his skin.

"Rain Tiger at Will Technique!"

The Rain Tiger at Will Technique had originally been a unique sensory ninjutsu created by Nagato in Naruto, using the Land of Rain's distinctive environment to infuse Chakra into the rainwater.

What Uchiha Yuan used now was his own version of the Rain Tiger technique. Because his technique consumed even more Chakra and could not yet be refined enough to sustain continuously, it could only be used as a one-time ninjutsu.

Rumble!

An enormous, invisible mass of Water Release Chakra rose into the sky, slowly condensing water vapor. Dark clouds gathered, and rain began pouring down.

The rain came suddenly, but in the midst of battle, no one noticed anything unusual about it. Yet when the raindrops fell upon those shinobi...

Whoosh!

Uchiha Yuan's figure instantly appeared behind an enemy shinobi somewhere within the clan grounds. One hand pierced directly through the man's chest.

"Pfft! Wh-when did...?"

He pulled back his hand, and the corpse collapsed. Uchiha Yuan hauled up a nearby clansman still reeling in shock. Without stopping, he used the Body Flicker Technique again and rushed toward the next location.

In the blink of an eye, the sounds of fighting throughout the Uchiha Clan Grounds rapidly turned into screams. More and more Uchiha Clan shinobi gathered, forming groups of three or five. Their disadvantage was immediately reversed, and they began actively purging the clan grounds.

"The clan head is still with us! Pull yourselves together!"

"Kill these bastards!"

"Guard the shrine! Everyone else, charge with me!"

Rumble!

Thunder and lightning tore through the night sky. At this moment, the tide of battle began to turn.

When the heavy rain began, some rejoiced while others despaired. When the clan grounds had first been breached, the Uchiha clansmen had felt as if a layer of gloom covered their hearts. But when Uchiha Yuan's conspicuous Divine Robe appeared, that gloom was torn apart, allowing dawn's light to spill through.

At Naka Shrine, only a little over a hundred Uchiha shinobi remained on guard. Everyone else had charged into the clan grounds to fight. The elderly and young clansmen within the shrine, who had originally been trembling with fear, gradually calmed down because that man was still there.

In their hearts, as long as Uchiha Yuan was present, every difficulty would be resolved. That was their clan head, the clan head who had changed the Uchiha.

It took Uchiha Yuan less than ten minutes to eliminate the rebels within the clan. He killed a total of 596 unidentified shinobi, whose clothing came from at least six shinobi clans.

"What a bizarre conspiracy... Have we been used?"

Uchiha Yuan knew he had never encroached upon the interests of these shinobi clans. Some of them he had never even heard of. Even if he had encroached on their interests, that had merely been the norm during the Warring States Period. Looking at the two battlefields outside the clan grounds, it seemed as though every shinobi clan in the Land of Fire had come.

"No, I remember this Fūma Clan is from the Land of Wind. That means shinobi clans from the surrounding countries have joined in as well. Are they kicking us while we're down? Or fishing in troubled waters?"

Standing atop a roof in the rain, Uchiha Yuan remained still. Another ten minutes slowly passed, and more and more clansmen gathered behind him.

"Have the wounded been settled?"

"Everything has been arranged, Clan Head!"

"Good! Then I'll have to trouble you all to continue singing the war song with me!"

"Yes!"

"Yes!!"

At this moment, Uchiha Yuan's Shadow Clone wore a bitter expression. He had discovered that the unrest within the clan grounds had already subsided. There was no need to say it—Little Kuro had successfully brought the original body over.

Sigh... This shouldn't be my fault. After all, I'm only a Shadow Clone...

Smack!

The Shadow Clone struck again, slapping an Akimichi Clan fatty to death. The spreading shadows behind him could not come within three meters of him, and the Yamanaka Clan's secret techniques had no effect on him whatsoever.

Watching these shinobi clans still desperately trying to stop him, the Shadow Clone curled his lip and muttered:

"Well~ while the original body is on his way, I'll use up more Chakra. He can deal with it afterward."

And Uchiha Yuan was indeed rushing over. The number of clansmen behind him had not decreased but increased instead. Looking carefully at those trailing behind, every one of them was wounded.

Uchiha Yuan's expression was numb as he took the lead and charged directly into the nearest battlefield. The Mangekyō Sharingan no longer spared its ocular power. After instantly controlling the enemy's five senses, he killed them with a single blow.

Killing people was much faster than fighting. There was no elaborate exchange of techniques—he used whatever was most sinister and whatever was most efficient. At this moment, life was especially cheap.

Whoosh! Whoosh! Whoosh!

A huge scroll was thrown into the sky and unfurled. Thousands of kunai scattered from it. Before they could even hit the ground, white light flashed past, followed only afterward by delayed screams.

Uchiha Yuan was like a reaper of life. Whether Jōnin or Genin, none could withstand even a single attack before him. Electric arcs crackled around his wrist, yet not a drop of blood stained him.

For some reason, the Shadow Clone exploded. The returning memories made Uchiha Yuan pause for a moment, then his gaze darkened further, and his Mangekyō Sharingan became even redder.

"Yamanaka Clan, Nara Clan, Akimichi Clan... Even those three clans came? Good!"

Those three clans, which had always remained neutral, had joined in as well. That made it even more likely that everyone had come.

At that thought, his heartbeat grew faster and faster, as though an emperor's engine had started roaring within his chest.

Half an hour later, Uchiha Yuan arrived at the third battlefield.

Looking at the conspicuous Susanoo giant and Wood Dragon giant, this force should have been led by the Senju.

Yet a massive barrier surrounded the area. The more Uchiha Yuan looked at it, the more familiar it seemed. It was clearly the Four Red Yang Formation.

"The Uzumaki Clan joined in as well... How did my Uchiha become the enemy of the entire Shinobi World?"

Uchiha Yuan was exceptionally skilled in Sealing Arts. After locating the four cardinal positions, he used the Body Flicker Technique to move over, casually dealt with the Uzumaki shinobi, and immediately led his group charging inside.

The moment Uchiha Yuan approached, he felt someone trying to seize control of his body. Such crude Yin Release manipulation was nothing before his Mangekyō Sharingan. The rebounding spiritual energy directly turned the brain of the hidden Yamanaka shinobi into mush, leaving him an idiot.

"Spread out. Stay as far away from the central battlefield as possible."

After issuing the order, he immediately rushed toward the great lake. His second brother was still fighting Tobirama there. The instant his gaze caught Tobirama's figure in the distance...

"Lightning Release Chakra Mode! Lightning Flash!"

Crackle! Sshh!!

A white line ignited across the water's surface, and the sound of tearing air exploded. Across a distance of more than a thousand meters, Uchiha Yuan was practically eye to eye with Tobirama in a blink.

His cells had been nourished by Chakra for a long time, and he had later fused with other genes. The speed he unleashed now surpassed the speed of light.

Tobirama only caught a glimpse of white light, confusion and incomprehension flashing across his face at once.

"What is that?"

Bang!

His body had no time to react. Before he could even raise his hands, he was sent flying by a punch.

"Third Brother!"

"Why are you out here?!"

Uchiha Yuan had no time to explain. Now was the perfect chance to kill Tobirama, and he had no intention of wasting it. As for the plot... to hell with it.

Lightning erupted in his hand, and a Chakra sphere containing a storm condensed into shape. It held terrifying destructive power within it.

"Die!"

The Rasengan containing a portion of Natural Energy flew out, its flashing electric arcs resembling a tiny sun in the darkness.

Rumble rumble rumble!!

A hurricane swept through. Izuna forcefully suppressed the questions in his heart and raised his hand in defense. His hair was blown straight back strand by strand. It took a full five or six seconds before the gale subsided. When he looked up again, Tobirama's position had become a massive crater.

The Storm Rasengan's destructive force had pulverized every substance within fifty or sixty meters into particles. At the center of this Rasengan was even a magnetic field that blocked energy. Pure Chakra could not defend against it at all.

Seeing such destructive force, Izuna felt that even Susanoo might not be able to block it. He could not help stammering.

"Th-third brother, is Tobirama dead?"

"No. He was rescued."

"Huh?"

Izuna was stunned. Someone had been able to rescue a person beneath a ninjutsu of that power? What kind of expert was that?

Uchiha Izuna stood dumbfounded, suddenly feeling that the Shinobi World before him had become unfamiliar.
