My Name Is "Kite"

In his past life, Izuna was a terrible student, but he was quite interested in history.

Throughout the history of warfare, there were countless examples of enemy alliances being dissolved through schemes of sowing discord.

For instance, during the Sengoku period, Qin fought against the six other states, and in the Three Kingdoms period, Cao Cao faced an alliance between Ma Chao and Han Sui. Both instances saw the enemy alliances dissolved through schemes of sowing discord, leading to victory.

According to Sora Uchiha's description, clans like Fuma and Saito had their fair share of minor skirmishes in the past over grain resources.

The other four clans were merely united temporarily under Masashige Hagoromo's leadership, coveting the Uchiha's fertile lands.

Izuna was confident that he could find an opportunity to break their alliance.

Currently, the Ino-Shika-Cho alliance had no plans to advance from their territories, so for the time being, they could rest easy.

However, less than three weeks after the first battle, the five allied clans had grown bolder again.

They launched successive attacks, but all were repelled by the Uchiha.

Among them, although Kōkawa Yokōichi was killed by Izuna, the Onigawa Clan did not withdraw from the allied forces. Instead, they nominated Kōkawa Yokōichi's younger brother, Kenji Kōkawa, to take over as the new clan head.

In today's battle, even the alliance leader, Masashige Hagoromo, personally intervened. Although he appeared late in the latter half of the war, his strength was undeniably at the Kage level.

Izuna, without using his Mangekyo, did not manage to kill his opponent.

Before the end of today's battle, as Izuna and Masashige Hagoromo's final exchange concluded.

Izuna clearly heard the old man Masashige Hagoromo say to him in a teasing tone, "That power of yours... it seems you can't use it continuously."

The drawback of the Mangekyo had been seen through. Although Izuna had expected it, he couldn't help but feel annoyed.

"The enemy's attacks will become more frequent from now on, so everyone be careful."

After returning to camp to rest, Izuna ordered Sora Uchiha.

"Yes."

Sora Uchiha nodded in response, dragging his blood-stained body away.

Izuna opened the system skill tree:

[Current Skill Points: 86]

Enough!

What Izuna had been waiting for during this time was the Flying Thunder God Technique.

With a thought, the semi-transparent text on the light screen quickly changed. The "86" in the skill points column rapidly decreased to "6."

Simultaneously, the previously dim line for Flying Thunder God became bright at the very front.

[Flying Thunder God Technique (B-rank): Learned] → [Flying Thunder God - Second Stage (A-rank): Unlocked, Required Skill Points: 40] → [Flying Thunder God - Third Stage (S-rank): Unlocked, Required Skill Points: ??]

The A-rank Flying Thunder God only required 40 points?

Izuna blinked, but then quickly understood. The learning condition for the Flying Thunder God - Second Stage, in addition to skill points, required having already learned the basic Flying Thunder God Technique.

This meant that the total cost would be 120 points.

Knock knock knock~~

After mastering the Flying Thunder God, a knock sounded at the door shortly after.

"Come in."

Creak~~

The old wooden door opened with a teeth-grinding sound.

Ise Uchiha entered, holding a small wooden box, and said in a low voice, "Vice-clan leader, the items you requested."

"Thank you for your trouble. Put the items down, and you can go rest."

Izuna, with his back to him, was fiddling with the Flying Thunder God Kunai he had just taken from the system space.

"Vice-clan leader, you need these items..."

Before Ise Uchiha could finish speaking, he suddenly felt the temperature in the room drop significantly. He quickly said sheepishly, "S-subordinate will take my leave, subordinate will take my leave!"

Thud!

The wooden door was closed again.

Izuna lifted the lid of the wooden box. Inside lay an orange spiral mask with a single eyehole, and a pure black robe.

After putting them on, Izuna looked at his reflection in the window.

Yes, this was exactly how Uchiha Obito, under the alias "Tobi," dressed in later generations.

Bang!

He formed a cross-hand seal, and as a cloud of smoke billowed beside him, another Izuna appeared in the room.

Shadow Clone Technique!

Although the possibility of using it was slim, it was good to have one just in case.

Whoosh!

The next second, Izuna opened the window and fiercely threw the Flying Thunder God Kunai in his hand towards the sky ahead, a distance of at least a li.

Vanishing from his original spot for no reason, almost at the same time, Izuna reappeared a hundred meters in the air where the Flying Thunder God Kunai was.

Enduring the strong wind from above, Izuna grinned excitedly, grabbed the kunai in mid-air, and threw it forward again.

Disappear, reappear, disappear, reappear!

In just a few seconds, he had completely distanced himself from the Uchiha camp.

Even for Jonin-level ninjas, it would take at least three days to get here from the Uchiha's northwestern stone city.

With the enhancement of the Flying Thunder God, Izuna arrived by dusk on the second day.

Looking out from the cliff, the flags hanging at the edge of the canyon bore two different clan emblems, one on the left and one on the right.

The Sarutobi Clan and the Shimura Clan!

The reason their clan emblems appeared on the same flag was simple: like the Ino-Shika-Cho trio, their clans were allied.

Moreover, their alliance had a long and strong history, even going so far as to place their clan emblems on the same flag to demonstrate the two clans' unity.

The combined strength of these two clans could even rival the Hyuga Clan, who were second only to the Uchiha and Senju powerhouses in the Sengoku period.

Or perhaps, it was not impossible for them to surpass them.

So, was the marriage alliance between Hiruzen Sarutobi and Shimura Danzō forged back in the Sengoku period?

Izuna, wearing Obito's mask, let out a sneer internally, tossed a Flying Thunder God Kunai into the air, and vanished from his spot again.

At this time, in the territory of the Sarutobi-Shimura Alliance.

Furukawa Sarutobi and Keizou Shimura, the leaders of their respective clans, sat opposite each other, enjoying dinner.

"Furukawa, currently, with the Hagoromo Clan leading the charge, five clans are jointly attacking the Uchiha's northwestern border, and the Senju in the east could attack at any moment. Why don't our two clans take this opportunity to also..."

Keizou Shimura poured a cup of wine for his old friend, his eyes gleaming.

His intention was clear: to seize an opportunity and gain something for themselves!

However, perhaps it was fate, but Furukawa Sarutobi and Keizou Shimura, the grandfathers of Hiruzen Sarutobi and Shimura Danzō respectively, had a relationship very similar to theirs.

Although they belonged to the same alliance, Furukawa Sarutobi belonged to the cautious faction, maintaining a neutral stance towards the Uchiha and Senju, unwilling to offend either.

Keizou Shimura, on the other hand, belonged to the radical faction, always hoping for the Sarutobi and Shimura clans to replace the Senju and Uchiha and become the two strongest clans in the Sengoku period.

"Don't underestimate the Uchiha, Keizou."

Furukawa Sarutobi took a sip of wine and said, "It's still uncertain whether the Senju and Uchiha will fight. They just signed a truce agreement less than half a year ago..."

Keizou Shimura snorted, "That's just a piece of paper. How could the Senju, the sworn enemy of the Uchiha, let such a golden opportunity pass them by?"

BOOM!

The moment Keizou Shimura finished speaking, a loud noise erupted from the roof.

As the wooden pillars supporting the roof cracked and collapsed, a kunai embedded itself in the center of the tatami mat in the main hall.

The instant the kunai hit the floor, a dark shadow appeared.

"Who's there?!"

More than twenty ninjas from the Sarutobi and Shimura clans guarding the entrance to the main hall rushed in.

Furukawa Sarutobi and Keizou Shimura also immediately drew their weapons and assumed combat stances.

"My name is... Kite."
