Konoha: You're letting me build up my bonds, but you're offending the entire ninja world.

He lost an eye and was hit several times by Danzo, leaving him with almost no strength.

The most despicable thing is that the Root ninjas even used poison.

Having exhausted his last bit of strength, Uchiha Shisui managed to break free from the poisonous fog, but he still inhaled some of the toxic gas and collapsed against a tree, gasping for breath.

"Aim for 09's legs, avoid his face!"

The Root ninjas all fired kunai with explosive tags attached to them.

Rumble!

A massive amount of chakra surged from Uchiha Shisui's body, enveloping him in a turquoise half-body armored warrior, blocking the aftershocks of the explosive tag's detonation.

Susanoo!

This strongest genius of the Uchiha clan once again demonstrated his astonishing talent. Even though he was seriously injured and had lost one of his Mangekyou Sharingan, he still used the ultimate eye technique hidden within the Mangekyou Sharingan.

The armored war god raised his hand and fired hundreds of energy arrows.

Each arrow was equivalent to a powerful ninjutsu, and the dense attack quickly broke through the Root's battle line. If it weren't for the presence of the chakra armor, there would have already been casualties.

"Cough! Cough!"

Uchiha Shisui coughed up a mouthful of blood, swung the lightsaber in his Susanoo with all his might, knocking all the Root units away, and then disappeared along with the green giant.

The moon rises above the treetops.

Having shaken off the Root's pursuit, Uchiha Shisui contacted Uchiha Itachi using a coded message and then went to the cliff where Itachi often trained.

"Stop the water!"

When Itachi Uchiha arrived, he was shocked to see that his friend only had one eye left, and he activated his Sharingan.

"I failed."

Uchiha Shisui gave a bitter smile. "Danzo didn't believe me. He stole my right eye, wanting to resolve the conflict between the village and the clan in his own way..."

"Danzo..."

Itachi Uchiha clenched his fists in anger, wishing he could rush to Root immediately and perish together with Danzo.

“It’s not his fault.” Uchiha Shisui shook his head and slowly walked to the edge of the cliff.

"I was too naive; I made a decision without thinking things through."

He recalled his conversation with Gengetsu Shimura that day, "Yes, how can simply changing one party's mind be enough? Who would allow the power to rewrite the will of others to be in my hands?"

"Lord Xuan Yue, I truly regret not having carefully considered what you said."

"Zhishui, let's not talk about this now. I'll take you to heal your wounds."

Uchiha Itachi could see that his friend was seriously injured and hurriedly tried to comfort him.

"no need."

Uchiha Shisui shook his head slightly. "My existence is a mistake. The clan will rely on me for military strength. Once war breaks out, Konoha will definitely become weak, and other countries will take the opportunity to invade. I cannot let the flames of war reignite because of me."

"Shisui..." A bad feeling rose in Itachi Uchiha's mind.

"Itachi, I'm entrusting this eye to you."

As if unplugging a plug, Uchiha Shisui calmly removed his left eye from its socket and handed it over, saying, "I hope it can help you protect Konoha and the honor of the Uchiha clan."

Itachi Uchiha did not reach out to take it. Only after Shisui Uchiha repeatedly urged him did he summon a flock of crows and place the eye into the body of one of the crows.

"Don't save me. Only my death can quell the ambitions of the clan and buy you time to grow. Farewell, Itachi. Leave the will at home and give it to the elders. They will think I committed suicide."

Having explained everything and fulfilled his final wish, Uchiha Shisui smiled and fell backward, letting himself plummet into the bottomless abyss.

"Stop the water!"

Uchiha Itachi reached out to grab it, but what he touched was just an illusion.

Unbeknownst to him, he had once again fallen under Uchiha Shisui's genjutsu.

"Forgive me, this is the last time."

Watching the figure fall into the dark abyss, Itachi Uchiha hated for the first time why the Sharingan's vision was so good; he could even clearly see the relieved smile on Shisui Uchiha's face.

Watching his best friend Shisui die before his eyes, Itachi Uchiha's emotions reached their peak, and a strange chakra suddenly secreted in his brain.

His eyes stung terribly, and streams of bloody tears flowed out. The three tomoe swirled and linked together, forming a pair of windmill-shaped Sharingan eyes.

He awakened the Mangekyou Sharingan at the age of eleven, and his strength steadily reached the Kage level. However, Uchiha Itachi felt only endless sorrow and even hated his own eyes and the dirty method of awakening them.

Below the cliff, the river did not stop flowing because of Uchiha Shisui's fall; it continued to rush into the distance under the impact of the waterfall.

Uchiha Shisui did not die immediately after falling into the river, but he had no strength left to struggle and simply let himself slowly sink to the bottom of the river.

Until... someone pulled him out.

The water flow formed a circular water prison that enveloped Uchiha Shisui, and then dragged him ashore.

"Cough! Cough!"

Uchiha Shisui coughed up river water with difficulty, and weakly asked as he heard Hashirama's approaching footsteps.

"Is...is someone from Root?"

"You've come too late. I've already destroyed the other eye. Just kill me. I'm a useless cripple now."

"Tsk."

With just a soft, ambiguous hum, Uchiha Shisui realized the identity of the newcomer.

"Xuan, Xuan Yue?"

When Danzo ambushed him, Shimura Gengetsu didn't appear, nor did he appear when Root was chasing him, yet he somehow appeared just before his death...

This was something Uchiha Shisui never expected.

Uchiha Shisui could sense that Shimura Gengetsu had crouched down and was right next to him.

"By all accounts, I'd say I'm practically a member of Root, but what Shisui-senpai said later was incorrect."

A green light shone from Shimura Gengetsu's hand and was placed on Uchiha Shisui's body, whereupon his injuries began to slowly heal.

"First... you are the famous Shisui of the Body Flicker Technique, and you didn't rely on the power of the Mangekyou Sharingan to make that name."

"Secondly...you didn't destroy the other eye either. Let me guess...was it in Itachi's hands?"

Uchiha Shisui was suddenly jolted, his mind going completely blank.

"Alright, stop trying to fool me with lies. Your body's reaction is the most truthful thing."

Gengetsu Shimura treated him slowly and deliberately. "Shisui-senpai, I'm actually quite curious. Do you regret telling the Konoha higher-ups about the function of your eye technique?"

After a few seconds of silence, Uchiha Shisui shook his head.

"I don't regret it, but I was too hasty and didn't realize that people's feelings can't be communicated. If I were in the position of the Third Hokage or Elder Danzo, I wouldn't trust an Uchiha clansman either."

"Even if he has already shown enough loyalty."

“You’re right. I must resolve the suspicions between the two sides at the same time in order to completely quell everything, but I’m not capable of doing that.”

[The host's regretful bond with Uchiha Shisui has reached the third stage, rewarding the user with Uchiha bloodline (ultimate)]

Uchiha Shisui pleaded, "Gengetsu-kun, please do me one last favor: kill me, or throw me back into the river."

Gengetsu Shimura stopped his Healing Palm Technique. "Answer me one more question, and I can consider it."

"go ahead."

"Are both of your Mangekyou Sharingan's eye techniques Kotoamatsukami?"

"Senior Shisui, I hope you will consider this carefully before answering me. This not only concerns your life and death, but also determines my attitude towards Uchiha Itachi. If he is too much of a threat, I will not hesitate to launch a sneak attack and kill him."

"Even if he awakened the kaleidoscope because of your death, I am absolutely certain."

"Don't threaten me with Itachi, Xuan Yue."

Uchiha Shisui sighed, "Giving that eye to Itachi was just a precaution. It's good that you know."

"My two Mangekyou Sharingan have indeed given birth to the Kotoamatsukami genjutsu, but there are differences between the left and right eyes."

"Elder Danzo's right eye is the Kotoamatsukami, which consumes less energy and is more concealed when activated, but its power is also reduced, and there is a risk of it being detected."

"And the left eye that was handed to Itachi, I call the light of Kotoamatsukami, or the true Kotoamatsukami."

"The light of Kotoamatsukami can be considered a one-time eye technique. Once used, it cannot be activated again for ten years. However, its effect is extremely powerful. Even if the illusion is seen through, there is no way to break it."

"I originally intended to use this eye to change the will of the Fugaku clan elders and persuade them to give up their hostility towards the village."

"Is this so..."

When Shisui was introducing him, Shimura Gengetsu kept his hand on his heart, feeling the changes in his heart rate to distinguish between the real and the fake.

If Uchiha Shisui were healthy, he would have been able to evade his lie detector test through various means, but the knowledge he had just received from the treatment had given him a much better chance of survival. Whether he was lying or not, it was impossible to hide it from Shimura Gengetsu.

What Uchiha Shisui just said was the truth.

Although the threat is still significant, that's about it. The power of the possession on the crow is incomparable to that of Shisui Uchiha's version. With this precaution in place, even if Itachi Uchiha wanted to use this move on him, he wouldn't have the chance.

"Lord Xuan Yue, I have already told you what you wanted to know. Please, just kill me now."

"I just said I'd consider it... I didn't give you a direct answer."

"Now that I've thought it over, I think you can't die yet."
