Kurama still remembered that the last time he was so angry was when he was controlled by that damned Uchiha Madara, humiliatingly serving as a mount.
And this human in front of him, whom he could kill with a single slap, was acting so arrogantly because of this hateful seal.
Even his two Jinchuriki, Uzumaki Mito and the current Uzumaki Kushina, only tried to communicate with him, never provoking him like Ren did.
"Tch, useless fox."
Ren was completely unfazed by the enraged Nine-Tailed; he raised his head and met the bloodshot giant eyes, saying loudly,
"Hey, dead fox, I came today to tell you to behave in the future. Any objections?"
"Roar!!"
His response was still a roar. Ren raised his hand to block the gust of wind, touched his blown-out hair, and gritted his teeth, saying,
"Fine, so you have a loud voice, huh."
Saying that, Ren turned his head to look down and said in a low voice,
"Minato-bro, let's go out for a bit."
"Oh, alright."
Although he didn't quite understand what Ren was going to do, Minato and Kushina still disconnected the Chakra link between them. The next moment, the three people in reality opened their eyes simultaneously.
After Ren regained consciousness, he raised his hand and took out a storage scroll from his waist. After a few hand seals, the white mist dispersed, revealing a dusty-looking jar, its body wrapped in a large number of sealing talismans.
"Minato-bro."
Ren turned to look at Minato and nodded.
"I need some of the Nine-Tailed's Chakra for research. Could you and Kushina-nee control the seal and cooperate with me?"
"Nine-Tailed Chakra?"
The two were a little surprised. Minato looked at the jar and immediately understood.
"So, when you borrowed this jar from me, it was to hold the Nine-Tailed's Chakra."
This jar was the container that had previously sealed Three-Tails. Later, when Three-Tails was sealed inside Ren's body, this sealing container was also taken by Minato.
Earlier, when the two were about to set off in the office, Ren suddenly asked him to bring the jar but didn't say why. Now, Minato finally understood.
"That's right, I need to do some experiments, so I've come to trouble you two today."
Ren chuckled as he picked up the jar lid and smiled.
"Then, let's begin."
"Mmm."
Without further ado, Kushina was responsible for drawing the scattered Nine-Tailed Chakra out of the seal.
During this process, the Nine-Tailed naturally caused a commotion. After all, the few of them were extracting its power. Although it had a lot of Chakra and didn't care about a tiny bit, that didn't mean it was willing to give it to humans.
Just as the Nine-Tailed was causing a ruckus within the seal, Minato quickly moved to stabilize the seal. No matter how furious it became, it could only watch helplessly as its Chakra was extracted.
Outside, one could see strands of red Chakra emerging from Kushina's abdomen, floating in the air, slowly flying towards Ren, and finally falling into the jar in front of him.
After a quarter of an hour, Ren looked up at the two and said,
"That's enough, Minato-bro!"
Hearing Ren's voice, Kushina stopped pulling and firmly closed the slightly opened seal again. With Minato's cooperation, even if the Nine-Tailed was powerful, it could only rage ineffectually within its cage.
"Sigh."
Looking at the enraged entity before them, Chomei and Isobu, who had not yet left, exchanged glances and sighed helplessly.
Among the Tailed Beasts, the Nine-Tailed was the most prideful and had the biggest temper. Now, being confined in such a small cage, it was no wonder it was so agitated here.
"Isobu, Chomei!"
The Nine-Tailed lay on the bars, looking at the two beasts, and roared,
"You two actually forgave and submitted to humans! You're truly disgracing us Tailed Beasts!"
"Don't talk nonsense, Kurama."
Isobu narrowed its single eye, gently swaying the tail behind it, and said in a deep voice,
"We have never forgiven these humans who imprisoned us, nor have we submitted to them!"
"We just…"
Chomei glanced at Isobu beside him and continued,
"...gained a companion, that's all."
"Companion?"
Upon hearing this, the Nine-Tailed calmed down instead. It looked at the two beasts and laughed mockingly,
"What a joke! In the eyes of these damned humans, we Tailed Beasts are irrational beasts. They fear us, dread us, how could they possibly become companions?"
Just as it was laughing loudly, Chomei quietly added,
"Except for the old man."
At these words, the Nine-Tailed's laughter instantly ceased. Its expression stiffened for a moment before turning to anger, and it roared,
"That's different!"
In the Nine-Tailed's heart, only the Sage of Six Paths, who created them, was different from those damned humans.
It's still like this, as expected.
Looking at the enraged Nine-Tailed before them, Isobu and Chomei shook their heads simultaneously. Knowing the other's temperament, the two beasts didn't intend to persuade it further. After exchanging glances, they turned and walked into the darkness, their voices slowly echoing.
"Anyway, it was good to see you today, Kurama."
"Then we'll see you next time, Kurama."
Only after sensing that the two beasts' Chakra had completely disappeared did the Nine-Tailed calm down, lying on the ground, looking at the spot where the two beasts had been, a faint complex emotion in its eyes.
Meanwhile, outside, Ren was celebrating on the spot, holding the jar, his smile impossible to hide.
He finally got the Chakra of this useless fox. With this, there was so much more he could do.
"So, Ren, what exactly do you want to research with this?"
Kushina put down her clothes and sat up, looking at Ren with confusion.
"Ah, about that…"
Ren hid the jar behind him and smiled mysteriously,
"Please allow me to keep it a secret for now, Kushina-nee."
Hearing this, Kushina's face immediately fell. She turned her head to the side and mumbled,
"Tch, I don't even want to know."
"Honestly."
Looking at Kushina pouting like a child, Minato couldn't help but smile wryly. He stood up and said gently,
"Alright, you get some good rest. I'm going back to work now."
"Huh?"
Kushina sighed, but she also knew Minato was busy, so even if she was unwilling, she could only mumble,
"Go on, go on. Sister Meihui can accompany me."
Minato bowed slightly to Meihui, who was standing beside him.
"Then I'll trouble you to take care of Kushina, Sister Meihui."
"It's nothing, Hokage-sama."
Seeing the Hokage bow to her, Uzamaki Meihui quickly waved her hand and said,
"Taking care of Kushina is what I should do. You don't need to do this."
"Still, thank you."
Minato stood up and smiled.
"You can just call me Minato, Sister Meihui."
"Oh, alright."
Meihui was startled at first, then quickly responded.
"Then let's go, Minato-bro."
Ren, who had put away the jar, looked at Minato and nodded.
It was only noon, and there were still things to do.
