Faced with Xiaotian's death-seeking behavior, the system replied as follows:
"True immortality can only be achieved under the host's own will. If the host wishes to commit suicide, it naturally will not work. However, after consuming the Chakra Fruit, the host's body can no longer die naturally. In the host's current world, no one can kill you—not even you yourself at this moment."
Upon hearing this, Xiaotian was completely dumbfounded. "Chakra Fruit?" he asked. "When on earth did I eat a Chakra Fruit? And besides, does that kind of thing even exist in this world?"
Even now, Xiaotian had never suspected that he was in the world of Naruto. Besides, this world was very simple—there was only one monster, and Hagoromo's Rinnegan belonged to his son; wasn't it only natural that he possessed the Rinnegan?
"It was given to you by your wife, Kaguya."
When the system finished speaking, Xiaotian was stunned once more. "Given to me by Kaguya?" he muttered. "Ah, look, I told you so long ago—she must have been a transmigrator too, and she had a system as well. But since she's a foreigner, naturally she wouldn't understand those secret codes."
If the system had a physical body, it undoubtedly would have rolled its eyes at Xiaotian, because the man was simply too foolish.
"So how am I supposed to die now, then?"
Xiaotian sat up and began to ponder how he might kill himself.
Unable to hold back any longer, the system said, "Host, is it possible that Kaguya also ate the Chakra Fruit, and she was merely sealed away rather than killed?"
"Eh?"
Xiaotian froze for a few seconds before standing up. "You mean, as long as I hollow out the moon, I can see Kaguya?"
The system didn't answer, and Xiaotian had no idea whether it would work. "Say something, System!"
"Figure it out yourself."
With that, the system fell silent and refused to speak another word.
Xiaotian closed his eyes in deep thought. After a long while, it dawned on him. "No, that's not right. The power of Yin and Yang completely sealed Kaguya away; unless I possess a massive amount of energy, I still don't have enough right now... Ah, jeez, looks like I'll have to think of another way."
The system desperately wanted to curse out loud, but it could only stay silent, for silence was the only weapon against Xiaotian.
And so, two years passed, until Gamamaru summoned Xiaotian to Mount Myoboku.
Xiaotian was still very young at this time. The Yin-Yang True Formula could not grant him eternal life, but it kept him from aging, forever fixing his appearance around the age of twenty-five.
Only, Xiaotian looked a bit unkempt right now; his hair was a mess, and he didn't care much about his appearance.
Arriving before Gamamaru, Xiaotian asked, "Spit it out, why'd you call me here?"
"Old Man."
Hearing a voice, Xiaotian turned his head and caught sight of nine monsters. He jumped in fright, shouting, "What the hell are those? Why are there monsters here?"
"Old Man..."
The monsters looked somewhat dejected, yet Xiaotian had a feeling that several of them looked remarkably familiar.
Squinting his eyes, Xiaotian said, "Oh, I get it. You guys must be Hagoromo's pets."
Hagoromo wore a bitter expression. "Father, they are the energy of the Ten-Tails. After you split them up back then, I raised them, so they are your children as well. Let me introduce them to you: this is Shukaku."
"Old Man, I can use Wind and Magnet Release!" Shukaku said cheerfully.
Hagoromo pointed to a flaming cat-like beast next. "This is Matatabi."
Matatabi bowed deeply. "Old Man, I can use fire. If you ever wish to ride upon my back, it would be my honor."
"This is Isobu."
Behind Hagoromo stood a small fellow covered in armor, resembling a turtle.
The little creature Isobu smiled and said, "Old Man, I've finally met you. I can use water."
A red monkey thumped its chest. "Old Man, my name is Son Goku. I can use Lava Release, which is pretty much like fire."
"My name is Kokuo. Old Man, I can be your mount, and I use Boil Release."
Kokuo looked like a cross between a dolphin and a horse, and it was the most polite of them all.
"My name is Saiken. Old Man, don't look at me like this, I'm definitely going to be able to fly in the future."
Saiken looked very much like an insect and had no wings.
"Old Man, my name is Chomei, and I can do a lot of things. This one here is Kurama, and he's completely useless."
Gyuki looked like a hybrid between an ox and an octopus, yet he looked rather cute that way.
"Hey, jerk, what right do you have to speak of my name?! Old Man, I'm the strongest one here!"
As soon as he finished speaking, Kurama lunged straight at Gyuki and started fighting with him.
As for Xiaotian, he was utterly dumbfounded. Weren't these right before his eyes the Tailed Beasts? Though he didn't recognize all of them, he certainly recognized the One-Tail and the Nine-Tails.
"What the fuck? Can someone tell me what is going on here? Nine Tailed Beasts, and they're all my kids? No, wait... could it be that I actually transmigrated into the world of Naruto?"
Just as Xiaotian was thinking this, Hagoromo approached his side. "Father, those are their names. Since you were the one who split them apart, they are also the younger brothers of myself and Hamura."
Xiaotian took two steps back. "Wait, hold on a second. My head is a bit of a mess. Does that mean you're the Sage of Six Paths?"
The Tailed Beasts had all appeared, and Hagoromo was the one who controlled them—that made him the Sage of Six Paths.
"What is the Sage of Six Paths?"
Hagoromo had never been called that before and naturally didn't understand. Xiaotian hurriedly waved his hand. "Never mind, if you don't know, you don't know."
Xiaotian looked back at the nine Tailed Beasts. "Let's talk about you lot first. Since you all call me Old Man, I will treat you well. But children have to grow up eventually, and you must learn to be independent. Oh, right, make sure you don't scare any children."
"Understood."
The nine Tailed Beasts nodded in unison. Xiaotian stretched out a hand, and nine spheres of energy materialized, flying straight into the center of the Tailed Beasts' brows and melting within.
"This is my greeting gift. As long as this energy remains, no matter how you might be deceived or manipulated, I only need to call out to you, and you will be able to recover. Of course, you will also gradually recover on your own and no longer be fooled by others."
After Xiaotian explained, the nine Tailed Beasts smiled happily. He turned back to look at Gamamaru. "Speak, why on earth did you bring me down here? I've got things to do."
Now that he knew he was in the world of Naruto, Xiaotian needed to go back and check some records, because he wanted to figure out how Kaguya could be resurrected.
Gamamaru coughed. "First of all, I must state that I possess the gift of prophecy."
"Pro... phe... cy..."
Xiaotian narrowed his eyes, clearly disbelieving. Feeling insulted, Gamamaru cried out, "I really can prophesize!"
"Fine, no need to shout at the top of your lungs. Hagoromo, is this true?"
Xiaotian looked toward his son. No matter what, Hagoromo was his child and shouldn't lie to him.
Right, Xiaotian simply refused to believe Gamamaru.
Hagoromo replied, "It is true, Father. Gamamaru's predictions are extremely accurate."
"Oh, is that so? Go on then, let's hear it."
Xiaotian sat down to the side. Gamamaru let out a long sigh and said, "She will be resurrected."
Just as Hagoromo was about to ask something, Xiaotian let out a scoff. "Tell me something I don't know."
"Eh? Father can prophesize too?"
Hagoromo was shocked; he had never known his father possessed such an ability.
Xiaotian curled his lip. "A while back when I was on the moon, I tried to commit suicide, but I couldn't die. After looking into it carefully, I found out that the Chakra Fruit was the reason why I couldn't die."
"Father (Old Man) actually tried to commit suicide?!"
Hagoromo and the nine Tailed Beasts were all stunned. Xiaotian supported his forehead with his hand. "Then I figured out that Kaguya is just like me—she can't die either, only be sealed away. But the seal of the Yin-Yang power is too strong; I have no way to undo it, so I can only wait."
Hagoromo understood. "Father, are you planning to resurrect Mother?"
Xiaotian nodded gently. "Yeah, I want to bring her back and make her change her mind."
Gamamaru gave a strange smile. "That settles it then. You can indeed persuade Kaguya to change her mind, but the price is your death."
"What!"
Hagoromo and the nine Tailed Beasts were once again shocked, but Xiaotian let out a sigh of relief. "She'll change her mind? That's good, then."
In Xiaotian's mind, whether he lived or died didn't matter, as long as Kaguya could be resurrected. That was enough.
"Father..."
Hagoromo wanted to say something, but Xiaotian raised a hand to stop him. "No need to say anymore. Oh, right, Hagoromo, I happen to have an elixir of immortality here. Would you like to take it, or I can give it to your younger brother."
"This..."
Hagoromo looked at Xiaotian, and soon, he shook his head. "No, Father. I still have responsibilities, so I wish to go to the Pure Land after I die and manage the souls there."
The world of Naruto did indeed have a Pure Land, and Hagoromo was indeed its administrator, but Xiaotian knew nothing of this.
"Fine then, you just do a good job and protect this world. As for this elixir of immortality... give it to your brother."
Xiaotian tossed the elixir of immortality to Hagoromo and instantly vanished from the spot, because he needed to look up information.
Back on the moon, Xiaotian hurriedly asked, "System, I want the complete collection of Naruto. Do you have it?"
"We do. It will cost the host three thousand points."
As soon as the system finished speaking, Xiaotian slapped his hand down. "Full color! I don't want black and white."
The system replied, "Available. Thirty-five hundred."
"Exchanged!"
With that, a massive pile of books appeared before his eyes—these were none other than the complete collection of Naruto.
Activating the Rinnegan, Xiaotian immediately began to read, because he needed to understand how Kaguya was ultimately resurrected.
Half a day later, when Xiaotian reached the final few chapters, he burst out laughing. "Haha... Just as I thought, Kaguya is resurrected! Hmm, and she was actually revived by Black Zetsu? Wait a minute—since I came here, is Black Zetsu still around? Oh please, Black Zetsu, you've got to be here!"
At this very moment, in a corner of the earth...
A pitch-black child was currently looking up at the moon, muttering, "Mother, I will resurrect you, and then together we shall kill that heartless father of mine."
With that, the black child continued walking. He was none other than the Black Zetsu of whom Xiaotian spoke.
In the original history, Black Zetsu was Kaguya's creation.
Yet in this world, Black Zetsu's body contained not only Kaguya's power, but also a portion of Xiaotian's power.
Thus, Black Zetsu had been born from the combined powers of both Xiaotian and Kaguya, and just like them, he could not be killed through normal means, only sealed.
If Xiaotian had known Black Zetsu was right here, he surely would have tracked him down immediately to discuss how to resurrect Kaguya.
