"You are right; it's difficult for me to survive today. But do not make a mistake; if I wanted to, I could have easily retreated rather than fighting all of you. And you, who call yourself a god, are insulting the word 'god.' You required the help of three others to defeat me, a thirteen-year-old. Haha, it's funny, but I want to thank you all for one thing: you gave me a challenge for the first time in my life. After I was born, I had a quite smooth sailing life in terms of battle and combat, of course. But you were able to remind me that I have to become far more powerful than I am currently and have to work harder if I want to achieve the title of the strongest in the world, even in the universe," said Jiryoku.
"Hmph, stop your nonsense. We are far above what you can ever reach. Now, you can die," said Deva Path.
"That's why you came specifically to kill me, a thirteen-year-old boy, for eliminating future threats," said Jiryoku with a mocking smile on his face.
"Do not argue with him; just attack," said Obito.
After Obito's voice fell, they all attacked Jiryoku, trying to kill him in one shot. But suddenly, gravity descended on all of them. "What is this? What's with this suddenly increased gravity?" said Kisame.
"I have been working on it for a long time, but I was not able to master it due to my lack of stamina and control over gravity. But today, I will be using it for the first time in my life, and I will show you the miniature version of the power to destroy the world," said Jiryoku, blood flowing from his mouth, eyes, and ears. His body was taking a huge toll, and there were even sounds of his bones breaking.
"Lady Katsuyu, let all your small clones leave, or else they will be obliterated," said Jiryoku.
"What about you? Should I reverse someone for you?" said Katsuyu.
"Not now, I will tell you," said Jiryoku.
"Stop him! It seems he is going to use something very powerful," said Obito.
"I know," said Deva Path, and with that, all the Paths of Pain except Deva Path fell to the ground.
Deva Path used 'Almighty Push' with full power, capable of destroying a whole village, on Jiryoku. But as soon as it reached near Jiryoku, the effect was gone.
"What!? How is this possible?" said Nagato in surprise.
Obito from the side used one of the most powerful Fire Release jutsus he knows, "Fire Release: Blast Wave Wild Dance."
Itachi supported Obito from the sidelines by using 'Amaterasu,' amplifying the effect of 'Fire Release: Blast Wave Wild Dance' to a huge level.
The whirlpool of huge orangish-black flames traveled in the direction of Jiryoku. But, like the previous attack of Deva Path, this attack also failed, and it can be clearly concluded that the gravity has become more powerful.
"The use of ninjutsu is useless, and we can't get any closer. It is best that we retreat," said Itachi.
Jiryoku, who was feeling pain all over his body, shouted, "Yaaaaahhhh." With his shout, a small black dot was formed above him, and it continued to grow bigger and bigger until it reached a diameter of 50 cm. Then, it stopped growing.
The gravity had now increased to an enormous level, making it very difficult for anyone to stand near it. Itachi, the Paths of Pain, Obito, and Kisame had difficulty even breathing because the air itself had become heavy.
"Everyone, I present to you the power that can destroy the world: 'Black Hole!'" shouted Jiryoku.
As soon as Jiryoku's voice rang out, everything started getting attracted towards the black hole: the ground, trees, stones, and, not to mention, the people standing nearby.
"Lady Katsuyu, now," said Jiryoku, and as soon as he said this, he started feeling dizzy.
Upon hearing Jiryoku's command, Katsuyu in the 'Shikkotsu Forest' attempted to use the Reverse Summoning Jutsu. To her surprise, it didn't work. "Why didn't the Reverse Summoning Jutsu work?"
Katsuyu tried the Reverse Summoning Jutsu again, but once more, it failed. "Reverse Summoning Jutsu isn't working. It means only one thing: the space where Jiryoku is present has become unstable, and due to this, Reverse Summoning is affected by it."
Katsuyu attempted the Reverse Summoning Jutsu once more, but it failed again. Just as Jiryoku lost consciousness and his body started rising, he disappeared in a cloud of smoke. Finally, the Reverse Summoning Jutsu worked.
Although Jiryoku had left, Obito was horrified by the turn of events, as he wasn't able to use Kamui continuously. It was getting interrupted continuously. "What kind of move is this that can even affect the space?"
Nagato knew that it was impossible for him to save all the Paths of Pain, as Deva Path, the body of Yahiko, had become useless. What he cared most about was Yahiko's body, so he used the Asura path to hit the Deva Path with multiple missiles, propelling Deva Path's body backward.
With the Animal Path, he summoned a huge Rhinoceros and pushed Deva Path's body even further backward. By now, Deva Path's body had regained the ability to fly, so Nagato, using his full Chakra, made Deva Path, which was the body of Yahiko, get out of the range of the 'Black Hole' effect.
Obito, with difficulty, was able to retreat with Kisame, and Itachi used his Susanoo's hand like a hoe, stabbing it into the ground to move out of the Black Hole's range.
As soon as they walked out of the Black Hole's effect, the unstable black hole, as Jiryoku hadn't mastered it thoroughly, exploded. The amount of energy it released was massive. When the massive explosion subsided, everything within a 100-meter radius was obliterated without a trace of its existence, leaving behind a crater as deep as 20 meters.
