Uchiha Yuan teleported to Namikaze Minato's house. Despite the deep reluctance from both Minato and Kushina, they still handed Naruto over to Uchiha Yuan.
Uchiha Yuan teleported with Naruto to a cave outside of the Hidden Leaf Village, where Hyuga Asana was already waiting.
"Asana, let's begin!"
Hyuga Asana nodded and formed hand seals to activate the barrier outside the cave.
The barrier was mainly to prevent small animals or other people from entering during the tailed beast construction process.
Uchiha Yuan placed Naruto on an altar and then took out the chakra of the other eight tailed beasts.
He had already divided the chakra he collected from the eight tailed beasts into two parts earlier—this portion was meant for Naruto.
Uchiha Yuan first lifted the seal inside Naruto, causing the Nine-Tails chakra to rampage immediately, and Naruto's body started showing partial foxification features.
Seeing this, Uchiha Yuan activated his Mangekyō Sharingan and used his ocular power to forcefully suppress the Nine-Tails' chakra, then began injecting the chakra of the One-Tail into Naruto's body.
After the One-Tail's chakra merged with the Nine-Tails', there was no obvious change. Uchiha Yuan continued fusing the chakra from the Two-Tails to the Eight-Tails into the Nine-Tails' chakra.
Once the Eight-Tails' chakra was completely injected, the Nine-Tails chakra rampaged again. However, this time, its form was not that of the Nine-Tails but resembled the first-form Ten-Tails from the original work.
Spikes began to protrude from Naruto's body.
Seeing this, Uchiha Yuan immediately realized that the tailed beast chakra was treating Naruto's body as the Ten-Tails' vessel and was undergoing some kind of transformation.
He hurriedly used Yin-Yang Release to separate the nine portions of chakra. The moment they were separated, all nine chakras showed simultaneous mental fluctuations.
"Asana!" Uchiha Yuan called to Hyuga Asana beside him.
Responding, Hyuga Asana used her chakra to guide the nine chakras to re-fuse, with the Nine-Tails' chakra as the core.
The reason Uchiha Yuan did this was because the Ten-Tails was originally the God Tree, which was a creation of the Ōtsutsuki clan.
Hyuga Asana's bloodline had now regressed to ancestral roots, and her chakra had the characteristics of the Ōtsutsuki clan.
Under Asana's guidance, the nine tailed beast chakras fused once again.
This time, the spiritual fluctuation in the chakra became even stronger. Uchiha Yuan used his ocular technique Magatsuhi along with Annihilation, injecting massive ocular power into the tailed beast chakra.
Ocular power is a product of Yin Release, which represents spiritual power.
As Uchiha Yuan continued to inject his ocular power, the spiritual energy grew stronger and stronger.
Eventually, quantitative change triggered qualitative change—the spiritual energy gained its own consciousness, and the tailed beast chakra began to solidify.
A tailed beast, looking like a young fox, appeared inside Naruto's body.
This newborn tailed beast's soul was still very weak. Its eyes were closed, and it fell into a deep sleep inside Naruto.
"Did it succeed?" Hyuga Asana asked.
"Probably! The state of this tailed beast is no different from how the Sage of Six Paths initially created the tailed beasts—back then, they were like children, with no hatred toward humans. This newly born tailed beast is the same.
From now on, it will grow up with Naruto. Under the guidance of the Fourth Hokage and his wife, Naruto and this tailed beast will become the best partners," Uchiha Yuan said with a smile.
"The Fourth Hokage couple really are good people. A tailed beast raised in such an environment shouldn't harbor any hatred toward humans.
By the way, Yuan, how strong is this tailed beast?" Hyuga Asana shifted the topic.
"Right now, it's still in its infancy. Its chakra is probably about the same as the Six-Tails. When it matures, its chakra could reach the level of the Eight-Tails, maybe more.
Plus, this tailed beast has the chakra attributes of the other nine tailed beasts, so it's like half of a Ten-Tails. Theoretically, its chakra quality should be higher than that of any of the other nine.
Given these innate advantages, it definitely won't be weak. How strong it becomes will depend on Naruto and the Fourth Hokage couple."
Hearing this, Hyuga Asana nodded and didn't ask further.
After that, Uchiha Yuan and Hyuga Asana watched over Naruto for a full day and night. Once they confirmed there were no issues, Uchiha Yuan used a small sealing technique to temporarily separate the new tailed beast's chakra from Naruto.
This ensured that Naruto's growth wouldn't be affected while still allowing communication between boy and beast.
After everything was settled, Uchiha Yuan asked Hyuga Asana to go home and rest, while he teleported back to Namikaze Minato's home.
Ever since Uchiha Yuan had taken Naruto away, Kushina had not slept.
Worried about Kushina, Minato also didn't go to the Hokage office to handle official duties.
"Kushina, don't worry! Naruto will be fine."
"How can I not worry? If I had known, I would've followed along!"
Hearing that, Namikaze Minato sighed. He was also deeply concerned about Naruto, but at this moment, he couldn't worsen Kushina's anxiety.
So while comforting Kushina, he also hoped that Uchiha Yuan would bring Naruto back soon.
Swish~ Uchiha Yuan's figure appeared out of nowhere in Namikaze Minato's home.
Seeing this, Kushina immediately got up and rushed over, grabbing her child back into her arms.
After confirming that Naruto was unharmed, she was overwhelmed with emotion and wept with joy.
Namikaze Minato, seeing Naruto peacefully asleep, also let out a sigh of relief.
"Yuan, did it succeed?" Namikaze Minato asked.
Uchiha Yuan nodded and explained the newly born tailed beast's situation to him.
"Then this is like having a second child, isn't it?"
"You could say that."
"Looks like I'll need to spend even more time with the family from now on," Minato said with a smile.
After returning Naruto to the Minato couple, Uchiha Yuan teleported back to the Uchiha compound and took a nap.
After waking up, Uchiha Yuan began analyzing the process of merging tailed beast chakra to create a new tailed beast, preparing for the construction of his own mini-Ten-Tails.
Uchiha Yuan remembered how, after the first fusion of all nine tailed beast chakras inside Naruto, the signs of Ten-Tails transformation were very clear.
The fused chakra treated Naruto's body as the Ten-Tails vessel, causing some special changes in Naruto's body.
Based on this, Uchiha Yuan speculated that if he fused the nine tailed beast chakras within the arm of the Demonic Statue of the Outer Path, the statue's arm would likely directly transform into a Ten-Tails form.
At that time, if Uchiha Yuan used the Rat Talisman, he might be able to bestow intelligence upon the mini-Ten-Tails, making it controllable.
Thinking of this, Uchiha Yuan even had the urge to immediately start building the mini-Ten-Tails.
But he quickly suppressed the idea. It wasn't the right time yet. He needed to observe Naruto a while longer and ensure there were no hidden issues before starting.
