Katsuyu said, "I can take you to Ryūchi Cave, but I must tell you, you are not a descendant of Ryūchi Cave. If you enter, you will need to pass the test of the Three Great Snake Princesses."
"I must warn you, the final stage involves the White Snake Sage personally injecting natural energy into your body. If you can't endure it, you will go berserk."
"When that time comes, the White Snake Sage will eat you."
"The training method for Senjutsu in Ryūchi Cave is the most violent and dangerous among the Three Great Sage Regions!"
Ryou asked Katsuyu in return, "Then can you teach me Senjutsu?"
Katsuyu shook her head. "I am a Summoned Beast of the Senju Clan; I will not teach members of the Uchiha Clan how to use Senjutsu."
Ryou asked her again, "What if Tsunade and I have a child in the future?"
"..."
Katsuyu suddenly fell silent.
In the original work, Katsuyu's summoning scroll eventually fell into the hands of the Uchiha Clan.
Because Sakura married Sasuke, she changed her name to Uchiha Sakura.
Tsunade was struggling and muffled, seemingly wanting to say something, but Ryou ignored her and looked at Katsuyu.
Katsuyu thought for a moment. "It depends on your child's nature. If he is an evil Uchiha like you, I will not teach him Senjutsu."
"On the other hand, if he possesses the universal love of the Senju Clan, then I will recognize him as my master."
Ryou walked up to Tsunade and patted her face. "Did you hear that, Tsunade? Give birth to a healthy son for me in the future."
"The fusion of Uchiha and Senju bloodlines... this might just give birth to a Sage of Six Paths!"
Impossible!
Katsuyu shook her head inwardly; she was the Great Sage representing the past among the Three Great Sages.
She understood ancient matters better than anyone.
The Sharingan and Rinnegan were independent of each other; Madara did not awaken the Rinnegan simply by combining the Eternal Mangekyo Sharingan with Hashirama cells.
Rather, he awakened the Rinnegan because his identity as the reincarnation of Indra's chakra fused with the power of Hashirama, the reincarnation of Asura.
The awakening of the Rinnegan is the fusion of Yin and Yang giving birth to All Creation; essentially, the chakra of Indra and Asura derives the chakra of the Sage of Six Paths to obtain the Six Paths Power.
If Hashirama could integrate Madara's cells, he could also awaken the Rinnegan by a stroke of luck.
Even if Hashirama's eyes were just ordinary eyes!
Therefore, relying on Ryou and Tsunade alone would not be enough to give birth to a Sage of Six Paths.
Although their bloodlines were top-tier within their respective clans, they were still too far removed from Indra and Asura.
Unless Hashirama and Madara had an offspring, only then could they become a vessel for the Six Paths Power.
Katsuyu did not say this out loud, only reminding Ryou, "Evil Uchiha, do you want to go to Ryūchi Cave? If so, prepare quickly."
Ryou prepared for a while, first taking a life spore from his body and turning it into his own appearance to fool Madara.
Immediately after, he called Fish Ball, Fortune, and Nekomata over.
He instructed them on a few matters, telling them to maintain contact with him at all times.
Ryou was also afraid that he might never return from Ryūchi Cave, so he would need the Shinobi Cats' Reverse Summoning Technique to save his life.
After preparing everything, Ryou was ready to set off.
Before he left, Tsunade struggled, wanting to say something.
Ryou approached her and undid the Ritual Formula on her body.
Once her restraints were released, Tsunade hugged Ryou tightly and pleaded, "You bastard, can you not go to Ryūchi Cave?"
"The conditions for Senjutsu cultivation in Ryūchi Cave are too harsh. If something happens to you, I'll be left a living widow."
Katsuyu looked at Tsunade hugging Ryou in a daze, truly unable to understand their relationship.
Could everything just now have been roleplay?
Young people these days are playing in increasingly wild ways!
Ryou patted Tsunade's back and said to her, "Tsunade, no, I must master Senjutsu. Only then can I escape the control of that old monster Madara."
"Although the method of cultivating Senjutsu in Ryūchi Cave is harsh, it is simple and crude, making it the most suitable for me."
Could the White Snake Sage see if one has the aptitude for Senjutsu cultivation with just one injection of natural energy?
Ryou had fused the cells of Hashirama and Madara, as well as White Zetsu cells; such aptitude was second only to Madara and Hashirama.
Coupled with his Forbidden Jutsu, he had a full 50 lives. If he still couldn't cultivate Senjutsu, it would prove that the White Snake Sage of Ryūchi Cave was truly trying to screw him over.
In that case, he would have to control it!
Ryou said some comforting words to Tsunade. Tsunade also knew that Ryou and Madara were not on the same side; the stronger Ryou became, the better he could break free from Madara.
Ryou let go of Tsunade and glanced at Konan, who was standing nearby, hesitating to speak.
"Konan, if you have something to say, just say it!"
Konan walked over and gave Ryou a hug. "If you're not sure about practicing Senjutsu, don't force yourself."
Ryou nodded.
Konan then added, "Release Nagato! You captured him yesterday and still haven't let him go!"
Ryou rubbed his head and scolded Fish Ball, "Fish Ball, how can you be so selfish? Nagato is our partner; how could you keep him locked in a cell for so long?"
Fish Ball was speechless. Wasn't it you who told me to lock him in the cell?
"Fine, fine, I'll go release him in a moment and personally apologize to him!"
Everything that needed to be settled was handled.
Ryou glanced at Nono. At this moment, Nono's kneeling posture was quite alluring, and Ryou immediately felt interested.
"Katsuyu, can you wait for me to have a quickie before we go to Ryūchi Cave?"
━━(￣ー￣*|||━━.
Katsuyu was rendered utterly speechless.
"You bastard, get out already—"
Tsunade concentrated her chakra into her fist and sent Ryou flying out the window with her Monster Strength.
Ryou grabbed Katsuyu and, taking Candy with him, activated the Mayfly Technique.
This time, Ryou had Candy leave a clone behind as well.
Because he was always inseparable from Candy, if Candy were gone for a long time, Madara might become suspicious.
In fact, Ryou didn't know that Madara knew the moment he left the Hidden Rain Village.
Currently, in the underground space of the Gedo Statue in Amegakure.
Madara had already sealed the Seven-Tails within the Gedo Statue and was listening to Black and White Zetsu report on the situation at Hozuki Castle.
Ryou had unsealed the Box of Ultimate Bliss and released Satori.
Madara asked about Satori's abilities; he was somewhat uncertain about the information he had previously obtained from Ryou and wanted to verify it personally from Black and White Zetsu.
White Zetsu replied, "Satori is very powerful and possesses the ability of Malice Sensing. As long as someone harbors malice toward it, it can see through the opponent's thoughts and predict all attacks."
Madara became interested. "Not a bad ability. How did that kid Ryou defeat it?"
White Zetsu said, "Lord Ryou seemed to have found a way to bypass Satori's ability to predict malicious attacks. Finally, he worked with Shukaku's clone to seal Satori, and after subduing the Box of Ultimate Bliss, he took control of Satori."
"Shukaku's clone?"
Madara was somewhat puzzled.
Black Zetsu then explained that Ryou had absorbed the Tailed Beast chakra, allowing them to exist as clones so they wouldn't be swallowed by the Gedo Statue.
Hearing that it was only a portion of chakra, Madara didn't bother with it further.
Consequently, Madara didn't pay much more attention to Satori. In his view, while Satori's ability was decent, in front of him, it was just a matter of a single glance.
Nothing to worry about!
Madara sighed. "Perhaps I shouldn't have been resurrected by Ryou in the first place. This era... I really can't find a worthy opponent."
