"Yes, yes," the system replied immediately.
"Okay, there shouldn't be any problems with the bloodline fusion, right?" Shiyu asked.
"No problem," the system replied.
Immediately afterwards, Shiyu announced to everyone, "I will be going into seclusion for a period of time. During this time, I will be entrusting the Shinobi Village to you all!"
Everyone was deeply ashamed.
"Lord Shiyu, your strength is already so great, why do you still need to go into seclusion?"
"It truly makes us ashamed. Compared to you, we are really inadequate."
Shiyu said, "When I'm not around, everything still follows Yoshiki's rules; her words have the same weight as mine."
Uchiha Yoshiki is a top talent in governing the village, Shiyu naturally wants to continue training her.
After arranging everything, Shiyu used the Reverse Summoning Technique to return to the Hermit's Seat in Ryūchi Cave.
Upon sensing Shiyu's return, the Three Divine Maidens immediately bowed respectfully.
"Has anything happened recently? Is there anyone you'd like to acquire the Ryūchi Cave inheritance from?" Shiyu asked.
The Three Divine Maidens all shook their heads.
"That's true. It's already difficult enough to get to the outer perimeter of Ryūchi Cave, let alone pass your trials and enter Ryūchi Cave." Shiyu didn't think too much about it.
"I'm going into seclusion again for cultivation. I'll trouble the three of you to protect me." Shiyu still trusted the Three Divine Maidens quite a bit.
"Yes! Immortal!" The Three Divine Maidens then surrounded Shiyu in a circle, and Shiyu then began to talk to the system.
"System, now merge with the bloodline I've absorbed! Right now," Shiyu said.
"No problem. Let me see. Yes, it has the bloodline power of the Eight-Tails, as well as the pure bloodline of the Uchiha Clan. However, this fusion will be somewhat uncomfortable, and Isobu within you should undergo an evolution."
"Evolution? What will the Three-Tails evolve into?" Shiyu asked, also very curious.
The system replied, "I don't know because you have already collected all the different bloodlines of the Otsutsuki, and you have also fully absorbed the bloodlines of all nine Tailed Beasts. Now that you have fused with the Eight-Tails, the Isobu within you will definitely undergo changes."
Shiyu understood that the system only knew one side of the story and not the other, so he could only ask the system to help him fuse the bloodlines.
"Isobu. Shiyu softly murmured the name of the Three-Tails, but the Three-Tails and Shiyu were already in perfect harmony."
"I never imagined you possessed such a wondrous thing. No wonder you've become so strong. It's alright, go do what you want to do. The Shinobi World still needs you to protect it." Isobu, also made up his mind for Shiyu.
"Thank you." Although they hadn't known each other for long, Shiyu had come to regard Isobu within him as a friend. Isobu would always give Shiyu his chakra at crucial moments, and he never took advantage of her weakness.
"Let's begin the fusion!" Shiyu had made up her mind.
"OK!" Immediately afterwards, Shiyu felt as if the bloodline he had absorbed was being slowly devoured by the Otsutsuki cells within his body.
At first, there wasn't much of a noticeable difference, Shiyu easily fused with the bloodlines of Uchiha Shisui and Uchiha Itachi. However, after fusing with the Eight-Tails' bloodline, Shiyu clearly felt significant changes in his body.
"It seems that I have lost all feeling in my body. Shiyu then felt the chakra of the nine Tailed Beast slowly merging within his bloodline, and Shiyu's own Otsutsuki bloodline immediately became weaker."
"The bloodlines have merged, but it was actually the bloodlines of the nine Tailed Beasts that merged first? Does this mean the Ten-Tails is going to be resurrected?!" Shiyu was very anxious, but at this Shiyu was unable to move or control the cells in her body.
After the Tailed Beast bloodlines fused, they immediately merged into a completely new bloodline, Shiyu's Otsutsuki cells were unable to match for a time.
Shiyu was in excruciating pain, and large beads of sweat rolled down her cheeks.
"Wow. I didn't experience this much pain when fusing with the bloodline power of other Tailed Beast. I never imagined that fusing with an Eight-Tails would be this intense."
"Shiyu, although I don't know what's happening inside your body, I can feel that my body is about to change, "Isobu said with equal difficulty.
Immediately afterwards Isobu's tail suddenly swelled up, eventually becoming so huge that it could blot out the sky, and both Shiyu and Isobu felt unbearable pain.
"My body felt like it was being torn apart, but my will hadn't given up, "Shiyu continued, gritting her teeth and persevering.
However, at the same time Isobu's appearance underwent an even more exaggerated change. Isobu's Sanjo tails increased by one, and soon after, another tail was added, until Isobu had ten tails.
Shiyu's will was also on the verge of collapse.
"Hold on, Shiyu!" Isobu shouted, then said, "I'm afraid I won't be able to hold on any longer. But you can continue to hold on for me."
"We're friends, aren't we?" Isobu had barely finished speaking when he was immediately swallowed up, Isobu appearance completely transformed into that of the Ten-Tails God Tree.
After Shiyu created a new Ten-Tails within his body, his consciousness dissipated. No one has ever created a Ten-Tails directly within their own body before. Even the Sage of Six Paths sealed the Ten-Tails before becoming its Ten-Tails Jinchuriki.
Just as Shiyu's consciousness was about to be devoured by the New Ten-Tails, a voice came from beside him.
"Shiyu, you'll definitely be a great ninja!"
"Shiyu. The Shinobi World depends on you to protect it."
Shiyu's consciousness instantly returned to a sliver. "I am who I am! I am Uchiha Shigure, and I will not let anything devour me!"
"I'd rather perish with you all!" Shiyu then forcibly controlled his body and formed a hand seal, chanting, "Immortal Technique: Eight Dragon Reincarnation Technique!"
Immediately afterward, Shiyu's chakra was completely burned up, but at the same time, every cell in Shiyu's body was filled with explosively powerful energy.
"Bloody Power Mode!" Shiyu released his Yin Yang Seal as well, and countless chakra flowed into his body, all of which Shiyu threw into the incinerator that is his body.
Shiyu's entire body turned red, resembling the Gate of Death in the Eight Gates Released Formation.
Shiyu regained a sliver of willpower and immediately began to fight desperately. Then Shiyu felt another powerful bloodline begin to retreat steadily under her fierce struggle.
"You only think of running away now! It's over! I'm going to disappear from this world with you!"
"So what if we all perish together?!"
Shiyu sneered and devoured the bloodline bit by bit, and finally a wail came from Shiyu's body.
"Aww"
"What? You want me to let you go? But will you actually let me go?"
