"Minato! You!"
Kurama roared at Minato, it's gaze meeting Minato's indifferent eyes.
It took a while for it to slowly calm down. It slowly began to release its Chakra, gradually enveloping the divided Asura Chakra. This was entirely pure Chakra. After all, if it contained violence and malice, it would cause repulsion.
Seeing this, Minato no longer hesitated. He simultaneously guided the Yang Chakra to begin repairing Naruto's Chakra pathways and slowly guided Asura's Chakra. He fixed it into the Eight Gates acupoints inside Naruto's body, forming stable Chakra nodes.
As it reached the last node, the Gate of Death, the heart, the always gentle Asura Chakra finally showed some movement.
Seeing this, Minato shouted at Kurama, "Kurama, I'm counting on you."
"Tsk—"
Kurama pouted unhappily, but still obediently used its Chakra to intensify the wrapping around Asura's Chakra.
With Kurama's mediation, Asura's Chakra gradually calmed down.
Minato then formed another hand seal, guiding the Yang Chakra and Kurama's Chakra to perform a Fuinjutsu.
Evil Sealing Method!
The last strand of Asura Chakra was permanently anchored in Naruto's heart by the Evil Sealing Method.
And with Minato's success, Shinji, who was outside, saw a mark appear at Naruto's heart.
Following that, a facial pattern similar to Sage Mode Hashirama appeared on Naruto's face, disappearing the next second.
"Fourth Hokage, your plan is truly grand."
Even Shinji marvelled at Minato's boldness. Everything Minato had done was not to merge Asura's Chakra with Naruto's Chakra.
After all, to put it bluntly, if the two merged, would Naruto still be the original Naruto?
Minato's method of operation was to use a high-level complex Fuinjutsu to manifest Asura's Chakra from a latent state and use the jutsu to guide and anchor it in the Eight Gates acupoints within Naruto's body, establishing a controllable 'Chakra circuit'.
Simply put, if Naruto gains enough strength in the future, he will be able to rely on Minato's jutsu to directly use Asura's Chakra in combination and proportion to activate Sage Mode, similar to Hashirama.
Of course, this prerequisite is that Naruto's strength is sufficient to resist the erosion of Asura's Chakra and make it his own. Otherwise, this jutsu will forever remain only within Naruto's body. Moreover, there will be no possibility of any loosening.
Asura's Chakra had already been divided into eight parts by Minato, so there was no way it could break through the Fuinjutsu.
As long as Naruto's Chakra exists, it will continue to reinforce it.
Within the sealed space, Kurama lied down, slowly saying to Minato, "Minato, you are still so bold."
As it spoke, Kurama glanced at Naruto.
What kind of magic did this kid possess that made Minato so confident he could perfectly use his Chakra.
And Asura's Chakra will.
Anyone else could easily be eroded by accident.
Minato chuckled. Kurama's help made him feel much lighter in his heart. Whether it was due to his coercion or some other reason, the first time was the dawn of success.
"Dad, why are you like this again?"
As soon as Naruto woke up, he saw Minato looking like he did last time, his entire figure almost fading away.
"I'll inject Chakra into you now." Naruto said, then tried to form a hand seal.
Minato reached out and stopped him, saying, "Naruto, no need. I can already control your Chakra, and there's a huge amount of Yang Chakra readily available right now."
Minato pointed to the jar that had just contained Asura's Chakra.
With the formation of the jar and having just contained Asura's Chakra, these could now be considered ownerless.
"Kurama, I'll trouble you to look after Naruto for a while."
Minato bowed to Kurama, and then led Naruto out of the huge space.
Kurama did not respond, only watching Minato's gradually receding figure with deep eyes.
"Is the mental imprint on the Chakra almost gone?"
Kurama shook it's head, realizing it was being foolish, why did it care about this?
"I hope your son can bear your disappearance when it happens, Minato."
To experience companionship and then disappear again, that is not something an ordinary person can endure.
After speaking, Kurama lied down again and closed its eyes.
Walking through the sewer-like tunnel, Minato listened to Naruto recount recent events, smiling and continuously ruffling Naruto's head.
"Dad, you don't know how annoyed that arrogant Sasuke was when I got first place."
Minato squatted down and said gently to Naruto, "Heh heh, Naruto, it seems you have another companion."
Naruto pouted unhappily. "How could that be? That arrogant Sasuke isn't a companion."
His words, however, lacked the earlier force.
Minato didn't refute Naruto's words, but merely took the opportunity to say, "Alright, but Naruto, dad might have to stay in that jar for a while."
Naruto's eyes were slightly red, and he spoke dryly, "Dad, you're very weak now. If you need to recover, hurry and go in."
"Alright, with your teacher looking after you outside, I can be a little more at ease."
Minato smiled, patted Naruto's head again, and said with a bit of embarrassment, "It's just that I can't be with you for a while. I'm sorry, Naruto."
"Tsk, there'll be plenty of time later." Naruto puffed out his cheeks, without a hint of dissatisfaction on his face.
"Yes, there will be plenty of time later, Naruto. Hold this in your hand. You can give it to your teacher once you're outside." Minato said, placing a magatama-like object in Naruto's hand.
"This is a key. If your teacher gets it, he'll know when to use it."
"Alright."
Naruto reached out to take it, examining the object in his hand.
"Alright, then I'll look forward to seeing you next time, Naruto." After speaking, Minato stood up and pushed Naruto.
...
"Phew..., that stinky old man, just kicked me out like that." Naruto rubbed his head, complaining with great dissatisfaction.
"Naruto, is everything done?" Shinji, who had been waiting, asked.
"Yes, sensei." Naruto stood up and replied, then remembered something and looked down at his palm.
An extremely dark magatama-shaped object lay in his palm.
"Sensei, dad told me to give this to you." Naruto said, handing the item to Shinji.
Shinji reached out and took it, feeling the aura emanating from it, and couldn't help but exclaim, "It's just like you, Fourth Hokage, always keeping a trick up your sleeve."
