The Reason

With that, Hiruzen Sarutobi immediately used the Spirit Communication Technique to summon the Enma.

The moment the Enma came out, before he could say anything, Hiruzen Sarutobi shouted, "The Enma! transform into Adamantine Staff."

Without any hesitation, the Enma immediately transformed into the Adamantine Staff and landed in Hiruzen Sarutobi's hands.

In the next moment, the Adamantine Staff in Hiruzen Sarutobi's hand became bigger and longer, like a pillar that held up the sky, it swept towards Uchiha Tunan.

Wherever the Adamantine Staff passed, the stone pillars summoned by the immortal arts exploded one after another.

Uchiha Tunan slightly raised his eyebrows, and he was slightly surprised in his heart.

Such a simple move was actually more powerful than he had imagined, and it could easily break the stone pillars summoned by the immortal arts.

However, this kind of move might be invincible on the battlefield, but in a one-on-one situation, it was not so powerful.

Just as the Adamantine Staff was about to hit Uchiha Tunan.

Uchiha Tunan activated Thunder God Flash and jumped, avoiding the attack of the Adamantine Staff and quickly forming seals in the air.

Immortal technique - Hao Flame Dragon Technique.

A huge flame dragon shot out from Uchiha Tunan's mouth.

As soon as it appeared, it lit up the entire sky.

After the dragon head appeared, it seemed to roar towards the sky and then quickly circled towards Hiruzen Sarutobi.

Hiruzen Sarutobi was not afraid at all. He secretly used Earth Escape Ninjutsu and also raised a stone pillar under his feet, raising it into the air.

He held the giant Adamantine Staff with both hands and began to spin it quickly.

Adamantine Staff - Fierce Wind.

Boom ---

In an instant, the staff shadows of the Adamantine Staff joined together, and the strong wind was like an air bomb, blowing away everything in front of Hiruzen Sarutobi.

The forest fire that stretched for several miles suddenly became violent, and was blown away by the strong wind.

The broken stone pillars could not withstand the fierce wind, and they were broken into pieces.

Uchiha Tunan's immortal art - bold flame dragon stubbornly endured the strong wind.

He continued to rush towards Hiruzen Sarutobi.

However, the closer they got, the slower the Hao Flame Dragon became, and it gradually became difficult for them to move.

Finally, it reached a critical point. The Hao Flame Dragon opened its dragon mouth and let out an unwilling wail, turning into a sky full of fire that was blown back.

The moment the Hao Flame Dragon dissipated, Hiruzen Sarutobi put away the Adamantine Staff and quickly made a series of hand seals.

"Composite Ninja Technique - Multi-Wind Palm Sword Technique."

In an instant, the flames in the sky combined with the strong wind and turned into many rapidly spinning swords in their hands, attacking Uchiha Tunan who had already fallen to the ground.

Uchiha Tunan stood still and raised his head indifferently, looking at the dense wind and fire swords covering his body.

Boom ---

The glaring fire lit up the nearby area.

"He didn't dodge?"

Hiruzen Sarutobi frowned and said in disbelief.

He immediately made a hand seal and cast a perception ninjutsu, but he did not find the life aura of Uchiha Tunan.

"Impossible, how could he die so easily?"

Hiruzen Sarutobi muttered.

He felt his heart suddenly become empty. He didn't believe it and used perception ninjutsu again, but he still found nothing.

It seemed that he really died.

At this time, Hiruzen Sarutobi found that he didn't have the pleasure of revenge. Instead, he felt that he had lost the most precious thing.

The snow was getting heavier and heavier.

The heavy snow drifted in a dense manner and fell from the sky.

When it touched the forest fire, it melted into a wisp of smoke.

The fire gradually became smaller, and the smoke around became thicker and thicker.

Just like that, Hiruzen Sarutobi stood on the spot in a daze.

Time passed by bit by bit.

The fire was completely extinguished, and the surroundings were completely shrouded in a fog that could not be seen with one's fingers.

The clothes on Hiruzen Sarutobi's body were also gradually soaked in moisture, becoming bone-chilling cold.

Hiruzen Sarutobi only felt that he had never been this confused before, not knowing if he had done the right thing.

Suddenly, Hiruzen Sarutobi felt a fatal danger coming from behind him.

"zzzzzzzzzzzt ---"

When the ear-piercing sound of a bird's cry appeared, it was already within reach.

Hiruzen Sarutobi instinctively turned around and stabbed the Adamantine Staff in his hand towards the lightning in the fog.

"Pu ---"

Blood splattered everywhere and landed on the ground, creating bright blood flowers.

The scene seemed to freeze at this moment.

Hiruzen Sarutobi and Uchiha Tunan looked at each other.

They both had expressions of disbelief on their faces.

The Adamantine Staff pierced through Uchiha Tunan's heart.

The Kusanagi Sword in Uchiha Tunan's hand only cut off a strand of Hiruzen Sarutobi's hair.

Uchiha Tunan opened his eyes wide, and a bitter look appeared on his face.

"Ho ho ho... you really want to kill me... You have no mercy..."

Hiruzen Sarutobi's hand that was holding the Adamantine Staff trembled slightly, and he said with a complicated expression, "Tunan..."

Uchiha Tunan lay down with tears in the corner of his eyes, and a nervous smile appeared on his face. He said hoarsely,

"My Kusanagi Sword deliberately deviated, but your Adamantine Staff is aimed at the heart.

Haha, haha, no matter how good I am...

In your heart, I will never be comparable to those two pieces of trash!"

In the next moment, Uchiha Tunan's three Magatama Sharingan rotated rapidly and changed into the form of a Mangekyou.

Seeing this, Hiruzen Sarutobi was immediately stunned.

This is... Could this pair of eyes be...

The Mangekyou in Uchiha Tunan's eyes slowly rotated, revealing a sense of despair.

In the next moment, the surrounding scenery suddenly fluctuated.

Hiruzen Sarutobi woke up and looked around, but there was no sign of battle.

So it was an illusion.

For some reason, Hiruzen Sarutobi subconsciously breathed a sigh of relief.

The two of them were still in their original positions.

The difference was that Uchiha Tunan was half kneeling on the ground at this time.

He kept his head down and kept shaking. Drops of blood fell on the snow, soaking up blood.

The soft, light snowflakes were dense and fluttering, as if jade scales were millions of millions of falling from the sky, or like goose feathers fluttering in the sky.

Hiruzen Sarutobi looked at Uchiha Tunan in front of him with an inexplicable expression.

He felt that the anger in his heart seemed to have subsided, and he could not raise any resentment against Uchiha Tunan.

He whispered in a hoarse voice, "Tunan..."

Suddenly, Uchiha Tunan raised his head and roared.

"I have nothing left!!!

Why did you investigate the truth?"

His voice revealed endless sorrow...

The moment Uchiha Tunan raised his head, Hiruzen Sarutobi clearly saw that the three magatama in his eyes had changed into the same Mangekyou as in the illusion.

Moreover, the Mangekyou in his eyes was still rotating slowly.

He really awakened the Mangekyou.

Was it because I killed him in the illusion and hurt his heart?

Hiruzen Sarutobi closed his eyes and sighed, "Tunan, why did you kill Shinnosuke and Asuma?"

Hearing this, Uchiha Tunan smiled bleakly.

"I'm not stupid. I know everything.

As long as Shinnosuke and Asuma are here, you won't even look at me.

You don't even bother to look at the birthday present I bought for you.

No matter how hard I work, no matter how much I do for you, I can't compare to a blood relationship"
