Yuzuru Uchiha nodded. "It should be. Yin Release is closely tied to spiritual energy. It can materialize certain things that don't actually exist."
"Then that settles it," the Evil God replied with certainty, then continued answering Yuzuru's earlier question.
"The secret technique I use relies on blood as a medium. It uses spiritual power to establish a special, invisible connection between two people, causing both bodies to suffer the same injuries while transferring the connected party's life force to the one who initiated the connection."
"So Hidan's immortal body..."
"Is maintained by my spiritual power. And my spiritual power needs to be replenished by absorbing the life force of other individuals," the Evil God answered patiently. "That is also why I need him to constantly offer sacrifices."
The Evil God did not dare neglect any of Yuzuru's questions.
After all, the moment the other party realized it was lying, it would suffer terribly.
Yuzuru thought for a while, then continued, "Would it work if Hidan sacrificed domesticated pigs to you?"
The Evil God immediately said, "Yes. The life force provided by a pig is not much different from that of an ordinary human."
"Of course, the stronger the individual, such as ninja or ninja beasts, the more life force they can provide."
Yuzuru rubbed his chin. "Then why did you still make the followers of the Evil God Cult sacrifice humans?"
The Evil God fell silent for a moment before saying, "No matter how you look at it, I am still an evil god. A god in their eyes."
"Making them sacrifice humans gives it a little more style."
"Fair enough..."
Yuzuru nodded.
Just like Hidan sacrificing that fat pig earlier. It had honestly looked rather ridiculous.
After asking everything he wanted to ask, Yuzuru said directly, "Now write down the cultivation method you know."
The Evil God said in confusion, "Even if I teach you, it won't help much. The natural energy in the current ninja world is thin. Even if you succeed in cultivating it, the power you can borrow will still be extremely limited."
"That has nothing to do with you. Hurry up!"
Seeing Yuzuru's gaze gradually turn unfriendly, the Evil God hurriedly wrote down its cultivation method.
It did not want to experience that agonizing torture a second time.
After looking at the cultivation method the Evil God wrote down, Yuzuru carefully put it away, then used his powerful spiritual energy to scrape through the Evil God's mind.
"Got it."
After confirming there was nothing wrong with the technique, Yuzuru directly used a Truth-Seeking Ball to turn the Evil God into nothingness.
After all, it was a cultivator who had survived from ancient times until now. It could be considered a ruthless figure.
Yuzuru had no confidence in controlling such a being, nor did he want to control it.
Killing it outright was still the safest choice.
As for the Evil God, it had never expected to survive Yuzuru in the first place.
The only reason it had been so cooperative was because it feared Yuzuru would continue torturing it.
So when it was killed, the Evil God put up no resistance.
Because if their positions were reversed, it would have made the same choice as Yuzuru.
After dealing with the Evil God, Yuzuru directly activated Kamui and arrived at the Uzumaki clan's Mask Storage Temple.
According to his intelligence, after finding the Shinigami mask among the many masks, Yuzuru summoned a White Zetsu.
"Hello!"
As soon as White Zetsu appeared, it greeted Yuzuru enthusiastically.
Yuzuru ignored it and directly cast a Genjutsu to control it.
Immediately afterward, White Zetsu began forming hand seals according to Yuzuru's command.
"Snake, Boar, Ram, Rabbit, Dog, Rat, Bird, Horse, Snake..."
"Reaper Seal!"
After Yuzuru finished speaking, the temperature inside the Mask Storage Temple suddenly dropped slightly.
Immediately afterward, an extremely translucent soul body appeared behind White Zetsu.
The Shinigami!
However, after seeing White Zetsu, a clear trace of confusion appeared in the Shinigami's eyes.
Then, it saw Yuzuru staring at it without blinking.
"So you're the Shinigami..."
After hearing Yuzuru's words, the Shinigami immediately realized that the monster that had summoned it had been controlled by the man before it.
Although it did not know what the other party wanted to do, the Shinigami had already sensed that the man in front of it was an extremely dangerous figure.
Without hesitation, the Shinigami directly reached through White Zetsu's body and grabbed fiercely toward Yuzuru.
"Courting death."
Seeing the Shinigami's movements, Yuzuru sneered.
His right hand clenched in the air, and a Truth-Seeking Ball that appeared from nothing instantly transformed into a pitch-black longsword.
Slash!
Yuzuru swung the blade down, and the Shinigami's outstretched arm was severed on the spot.
Immediately afterward, the falling arm was swallowed by another Truth-Seeking Ball and directly turned into nothingness.
"Ah!!!"
With its soul damaged, the Shinigami let out a wail.
It finally realized that the man before it seemed to possess the power to kill it.
The Shinigami wanted to flee, but it discovered that it was inside a barrier and could not escape at all.
It looked at Yuzuru and actually spoke in human language.
"Who are you? Why did you set this trap for me?"
Hearing the Shinigami's words, Yuzuru said calmly, "I need your cultivation technique."
The Shinigami's gaze sharpened, and it said in a deep voice, "Who told you about that?"
"That has nothing to do with you." Yuzuru held the longsword transformed from the Truth-Seeking Ball in his hand. "I don't have much patience."
Seeing Yuzuru's disdainful look, the Shinigami was furious.
But facing Yuzuru, who could easily wound its soul, the Shinigami only dared to be angry and did not dare to speak recklessly.
In the end, it said in a low voice, "Undo the barrier first."
Yuzuru raised an eyebrow and asked back, "Do you think that's possible?"
The Shinigami said coldly, "Then how do I know whether you will kill me after I hand over the technique?"
Yuzuru smiled and slowly said, "That isn't something you should be considering. You... have no choice."
Faced with Yuzuru's threat, the Shinigami fell silent for a moment. In the end, it still chose to compromise.
After writing down its cultivation technique, it was just about to speak when it saw a pair of eyes glowing with faint purple light.
"You dare..."
The Shinigami only had time to utter those two words before Yuzuru forcefully invaded its mind.
Even though it specialized in cultivating the soul, before Yuzuru, who had already reached the peak of the Six Paths level, it had no ability to resist at all.
"Hmph! As expected, you hid a few tricks."
After comparing what the Shinigami had written with the contents in its mind and making some corrections, Yuzuru finally put the scroll away in satisfaction.
The next second, a Truth-Seeking Ball directly erased the Shinigami.
Although in the original story, the Shinigami could easily seal even the souls of the Nine-Tails, Hashirama Senju, Tobirama Senju, and others, Yuzuru had never taken it seriously.
After all, if these ancient beings truly possessed power capable of contending with Six Paths-level experts, they would not have been almost completely wiped out by Kaguya Otsutsuki and Isshiki Otsutsuki back when the fruit of the God Tree had yet to mature.
"The rest can be left to Orochimaru and the others to research."
A faint smile appeared at the corner of Yuzuru's mouth.
The Evil God cultivated the body, while the Shinigami cultivated the soul.
With these two techniques as the foundation, then using the inheritances of Mount Myōboku, Ryūchi Cave, Shikkotsu Forest, and other places as references, he believed they would definitely be able to create a cultivation method suitable for humans.
And it would be one that cultivated both the physical body and the soul at the same time!
