All of this started with that encounter when he went to Iwagakure to purchase supplies.
The innately evil Ōnoki, the moment they met, inexplicably radiated intense malice toward him, who was still young at the time.
This caused great harm to Renya's young heart.
From that moment on, Ōnoki was placed on his must-kill list.
It was just that he never found the right opportunity.
A few years ago, when he passed by Iwagakure while traveling, he originally wanted to kill that short man.
But without being able to use the Sharingan or Flying Thunder God, and with the narrow office making it hard to gain any advantage, he could only withdraw regretfully…
That time in the Land of Whirlpools, he had finally managed to seize an opportunity.
But he had captured three Kage at the same time—killing them all would have been too much of a waste, so he could only use them to pay off debts.
The key point was that Danzō wanted to exchange them for money, and Renya had no reason to kill them.
This time was different.
Wasn't it perfectly normal to kill a few Kage-level opponents on the battlefield?
So he killed the Mizukage and the Raikage without hesitation, and he certainly wasn't going to let Ōnoki in the sky go.
"Shorty, do you think that just because you're flying in the air, I have no way to deal with you?"
Renya's Mangekyō Sharingan stared at Ōnoki in the sky.
The attack range of ordinary ninjutsu is limited; when facing a ninja who can fly, there really isn't much one can do.
In the original story, Deidara relied on his ability to fly to brazenly invade Sunagakure, defeat Gaara, and abduct him.
The Sunagakure ninjas could only stand below and stare helplessly.
Although flying ninjas are somewhat troublesome, for Renya it was not difficult at all.
"Poison Master, are you really going to wipe us out completely?"
Ōnoki looked down at Renya below with an ugly expression and said through clenched teeth.
His chakra was now less than one-tenth of what it had been; if they really fought, he definitely wouldn't be Renya's opponent.
He could only stall for time and run away once the barrier dissipated.
"You were allowed to join forces to kill me, but I'm not allowed to kill you in return?"
Renya pointed at the two headless corpses on the ground, a cold smile curling at the corner of his mouth.
"Today, the three of you are going to lie together neatly!"
Ōnoki anxiously glanced at the barrier whose energy had not yet dissipated, still making a final struggle.
"Spare me. I'm willing to pay for my life!"
"Our Iwagakure is willing to surrender, and we will compensate Konoha for all losses in this war, and we will also provide an enormous sum as war reparations!"
He could not die here. He had not yet fulfilled his teacher's final wish of leading the village toward prosperity.
If he could survive, what did spending some money matter?
As long as he was still alive, he could make the village earn even more money!
"Shorty, you really look ugly like this."
Renya looked at Ōnoki, who was trying to bribe him with money, with utter disdain.
Didn't he know that what Renya lacked the least was money?
That little bit of pocket change wasn't even worth looking at.
"Alright. You've lived long enough. It's time for you to accompany them on the road."
Renya had no intention of continuing the conversation. He directly activated the Mangekyō Sharingan's ability, a line of bloody tears slowly flowing from his right eye.
"Hakuri!"
This was the first time he had used his right eye's dōjutsu since awakening the Mangekyō Sharingan.
Where his gaze focused, it could forcibly strip a certain attribute from the target, including but not limited to chakra, the five senses, memories, ninjutsu, and so on.
And what he intended to strip away was Ōnoki's Light-Weight and Added-Weight Rock Technique.
Ōnoki, who was trying to stall for time in midair, suddenly felt as if an extra shackle had been placed inside his body.
Before he could even react, his body began to plummet without any warning.
"What happened?!"
Why could he no longer use the Light-Weight Rock Technique?
Bang.
Ōnoki's short body smashed heavily into the ground, his face filled with confusion and blankness.
Without the Light-Weight Rock Technique, once he stood up, he wouldn't even reach anyone's height.
But now was not the time to worry about height.
He had lost—completely and utterly.
There was even a very high chance that he would leave his life here.
In this battle, he hadn't suffered any fatal injuries; he had simply exhausted his chakra.
But none of that mattered anymore.
The barrier, originally meant to deal with the evil Uchiha Renya, had unexpectedly become a cage that sealed them in.
The Mizukage and Raikage were dead, and he was about to die as well.
In his current state, even if he went all out, he could not defeat Renya.
He might as well lie here and wait for Renya to come and end his life.
"Sensei, I did my best."
Ōnoki lay in the muddy ground, the light gone from his eyes.
He was clearly mentally broken.
At some unknown point, Renya had appeared in front of him. What entered his field of vision were Renya's cold, merciless eyes.
In Ōnoki's eyes, the Renya before him gradually overlapped with the figure of Uchiha Madara.
Even today, the psychological shadow Madara had cast upon him still existed.
Several years ago, he had transferred the psychological shadow Madara left on him onto Renya when Renya came to Iwagakure.
He believed that as long as he killed Renya, those psychological shadows would disappear.
That was how he comforted himself.
He never expected that he couldn't defeat Uchiha Madara, nor could he defeat Uchiha Renya.
"Tsuchikage."
Renya held the tachi horizontally against Ōnoki's neck.
"Do you have any last words?"
The Mizukage and Raikage had been killed instantly, without any chance to speak their final words.
He intended to give Ōnoki an opportunity.
The cold blade pressed tightly against Ōnoki's throat, the sensation of death so vividly clear.
He looked up at Renya's utterly emotionless eyes and knew there was no possibility of survival.
This young Tsuchikage, at the final moment of his life, wore a complex expression on his face.
Anger, unwillingness, regret—finally turning into relief.
Before an absolute gap in strength, he finally lowered his proud head.
"Uchiha Renya… it is you who has won…"
He closed his eyes, as if using the last of his strength to say what he cared about most.
"I… on behalf of Iwagakure… surrender."
He suddenly opened his eyes, looking at Renya in a pleading manner.
"But… the condition is… that you do not harm those I brought, and all Iwagakure ninjas on the battlefield… let them… safely leave the Land of Rain…"
This was the last thing he could do as Tsuchikage at the final moment of his life.
Using his own dignity and life in exchange for his subordinates and the village's future living strength.
He stared fixedly at Renya, waiting for the final judgment, waiting for the answer that would decide the fate of countless Iwagakure ninjas.
Renya's gaze remained cold as he looked at Ōnoki.
Inside the barrier, there was deathly silence, with only the sound of raindrops tapping against it.
After a brief silence, Renya slowly spoke.
"Fine."
Hearing this, Ōnoki rarely revealed a satisfied smile and slowly closed his eyes.
"Thank you, Uchi—"
A flash of blade light.
Without giving Ōnoki any chance to react, not even letting him finish his words.
The sharp blade sliced through Ōnoki's neck, blood instantly gushing out and dyeing the muddy ground red.
The Third Tsuchikage, Ōnoki, fell.
