Night, in Shinji's home.
As Shinji drew the final stroke on Naruto's abdomen, the blood runes on Naruto's body seemed to come alive. They began to coil like tadpoles, eventually sinking into Naruto's body.
Looking at Naruto, who was sitting cross-legged, Shinji stood up, quickly formed hand seals, and then slammed his hands to the ground.
A ripple of Chakra spread out, and two streams of Chakra flowing on the ground formed a counter-rotating barrier around them.
Seeing the jutsu completed, Shinji stood up and looked around.
Minato really is a treasure trove. He even had a composite Fuinjutsu that combined two Chakra attributes to form a Chakra sensing isolation characteristic.
The purpose of this jutsu was to make any external sensing Chakra that touched it fall into an infinite loop of a maze.
If he could master Yang and Yin Chakra more proficiently, Shinji estimated that the power of this jutsu would be even greater.
However, now it was time to wait for Minato's signal.
Inside the sealed space, Minato opened his eyes the moment the runes sank in. He quickly formed hand seals, then slammed his hands down.
Four Symbols Sealing Style: Reverse!
With the activation of the Four Symbols Sealing Style, the blood runes written externally combined with it, gradually beginning to derive along Naruto's body Chakra pathways.
"As long as the cyclic characteristic of the Four Symbols Sealing Style can successfully establish a Chakra circuit, no matter where you're lurking, I can pull you out."
Minato's expression was firm as he began to manipulate it to the maximum extent.
Buzz—
A subtle sound rang out, and Minato immediately noticed it.
"I found you!"
Immediately, Minato then placed his index and middle fingers together on one hand and pressed them to the ground.
Outside, Shinji saw the Eight Trigrams Sealing Style appear on Naruto's abdomen.
He immediately stepped forward, formed hand seals, and then pressed his hands onto Naruto's Eight Trigrams Sealing Style, beginning to input Yang Chakra.
The appearance of the Eight Trigrams Sealing Style was the signal Minato gave him. Once it appeared, Shinji's Yang Chakra needed to be transferred into Naruto's body. This was to prevent damage to Naruto's physical body and spirit, which could cause the connection to be interrupted.
Just as Shinji's Chakra was being inputted, Kurama, inside the cage, opened its eyes.
"What are that Yang Release brat and Minato doing?"
Although he was still lying down, Kurama could sense the Yang Chakra filling Naruto's body.
"Strange, it's the Yang Release brat's Chakra, but why does it feel like it belongs to this Jinchuriki himself?"
Minato chuckled, sighing, "Shinji-kun's mastery of Yang Release is truly rare in the world."
As he finished speaking, he began to direct the Yang Chakra filling Naruto's body, slowly gathering it towards the sealed space.
"Next, we need to create a temporary vessel."
Inside the sealed space, Kurama, who was originally lying down, saw a vessel slowly forming outside the cage, somewhat resembling an urn.
"What the hell is that?!"
Kurama stood up and came to the front of the cage, carefully examining the urn filled with Yang Chakra in the accumulated water.
At this moment, Minato happened to walk in with Naruto's consciousness.
Seeing Kurama, Minato raised a hand and greeted, "Yo, Kurama."
Naruto, on the other hand, shouted, "Kurama! Long time no see!"
"Tch, brat! Don't just call me by my name!" Kurama first scoffed, then angrily yelled at Naruto.
"What's the big deal, you stingy old fox." Naruto pouted, very displeased with the petty Kurama.
"Alright, Naruto, go sit over there." Minato patted Naruto's head, speaking gently.
"Got it!"
Naruto responded, knowing that his teacher and father were busy, and quickly ran to the urn, sitting down cross-legged.
"Minato, what exactly are you trying to do?" Kurama looked at Naruto suspiciously, then asked Minato, who was not far away.
"Helping Naruto get rid of some things he shouldn't have." Minato chuckled, but his words carried a hint of coldness.
Upon hearing this, a trace of confusion appeared on Kurama's huge fox face.
Minato ignored it, stepped forward to the glowing urn, and formed a few hand seals.
Buzz—
An indescribable ripple emanated, and several Chakra chains shot out from the urn's form. They burst out of the sealed space, heading towards Naruto's heart.
Because the Chakra signature that appeared on the surface was Naruto's, Asura's Chakra, which had been clinging to Naruto's heart, showed no reaction. It was then bound by the chains and slowly enveloped.
"It's done!"
Minato clasped his hands together, guiding the chains back.
It wasn't until Asura's Chakra was pulled into the sealed space that Kurama couldn't help but widen it's eyes.
It said in disbelief, "Minato, do you even know what you're doing?!"
It wasn't that Kurama was worried about Asura's Chakra. After all, Asura was already dead, and even if there was Chakra with his aura now, to Kurama, it was nothing. After all, it only recognized the Sage of Six Paths.
"If you're not careful, the inside of this brat will vibrate, and he might even die."
Minato slowly placed Asura's Chakra into the urn, pressed his hands on it, and then spoke, "I know, so now I need your help, Kurama."
"???"
It's Kurama when you need him, and Nine-Tails when you don't, huh.
Kurama bared its fangs, shouting angrily, "Minato! Do you think I'm some kind of pushover?!"
"No, it's because if Naruto were to die because of this, you, Kurama, wouldn't be in a good place either."
Minato narrowed his eyes. Although his tone remained gentle, the underlying coldness was undisguised.
"..."
Hearing Minato say this, Kurama finally reacted.
Apparently, if the Jinchuriki died, it, the beast in the cage, wouldn't fare well either. Although it could be revived, Kurama had no idea how long that would take.
Seeing Kurama no longer speak, Minato smiled, then activated the jutsu.
The entire sealed space began to operate.
Minato was using the Eight Trigrams Sealing Style that sealed Kurama to maintain the shape of the urn, while internally using the Four Symbols Sealing Style to restrain Asura's Chakra.
???
Kurama, inside the cage, watched Minato's actions, unable to help but be dumbfounded.
This operation, I'm familiar with it!
Isn't this exactly what Minato used when he sealed it back then?
With the activation of the Four Symbols Seals, Asura's Chakra was divided into multiple fine streams, gradually guided to extend from the urn. It was then injected into the water surface of the sealed space, spreading towards Naruto's circulatory system.
"Kurama, now I'll trouble you to envelop it with your Chakra, to prevent Naruto's main body Chakra from rejecting this Chakra."
