The Strongest Senjutsu Inside the Snake's Belly

"Congratulations, Immortal! You have successfully broken through the barrier! Your strength has greatly improved! I'm sure no one in the entire world can rival you now!" The Three Divine Maidens immediately praised.

Shiyu smiled slightly and said, "You three, you certainly have a sweet tongue."

Shiyu's hands were already on the shoulders of the two Kamihime.

"Ah? An immortal? When... when did you appear behind us?"

The Three Divine Maidens all possess the Senjutsu of Ryūchi Cave, which allow them to conceal their presence and become invisible, and they also have extremely strong sensory abilities. Even so, they did not detect Shiyu's movements, which shows that Shiyu's transformation was extraordinary.

"This is my breakthrough after going into seclusion; I can Teleportation at will," Shiyu said with a smile.

"Next, I'll go back to the Sage Cave. The Black and White Immortals should have been waiting for me for a long time. I still need to learn one last Senjutsu." Shiyu then walked towards the Sage Cave.

As she walked, Shiyu familiarized herself with her newfound abilities.

"There's no need to use the Flying Thunder God Technique anymore. Now, I can use the Six Paths power to Teleportation to any place I can sense at will. Beyond my immediate vicinity, I can still quickly reach that place using the Yomotsu Hirasaka."

"And those Truth-Seeking Orb behind me can also freely transform into weapons I want to use. It seems my strength has really improved a lot. All of this is thanks to the Ten-Tails within me."

"I wonder if I can defeat Kagura Otsutsuki now? That guy's chakra is terrifyingly powerful."

Shiyu pondered, she arrived at the Sage Cave she had visited before. Now, Shiyu easily reached the Sage Cave using Teleportation.

"Oh my, Snake Sage, you've finally arrived! We've been waiting for you year after year!" The voice was naturally that of the White Snake Sage.

"Ha, haven't you noticed that his strength is no longer what it used to be? If I'm not mistaken, he should have already obtained the Senjutsu of the other two great immortal realms, right?" This voice belonged to the Black Snake Sage.

At this moment, the two immortals were not in human form, but in the form of giant snakes. One was Black Scaled Great Snake, and the other was White Phosphorus Snake. Upon Shiyu, Shigure realized that the two Snake Sages had merged into one, sharing a body, with only the snake heads being separated into two.

At this point, the two-headed snake already had a very obvious horn on its head.

"What's going on? You've merged into one? Is it for evolution? Or are you waiting for me?" Shiyu asked.

The White Phosphorus Snake said, "Firstly, it's for evolution; secondly, it's to wait for you. Black Scale is about to die, and if we don't do this, we won't be able to pass on our final Senjutsu to you."

The Black Scaled Great Snake added, "Now we're one, our strength has multiplied, and our lifespan has been extended. Perhaps we can even break through the final shackles and transform into a dragon."

Shiyu nodded and said, "I came here this time to learn the final Senjutsu. After all, the enemy's strength is still unknown, and I need to make all the necessary preparations before setting off."

"It seems your Shinobi World has also encountered an unknown enemy. The world is in turmoil these days. Since you have already mastered the Senjutsu of other immortal realms, it seems you are the best candidate to learn the ultimate Senjutsu," said the Black Scale Sage.

"But I don't know if you dare to learn it?" the White Phosphorus Snake asked.

"What's there to be afraid of? With my current strength, who can possibly defeat me?" Shiyu was extremely confident. He simply wanted to add another method to his existing abilities.

"Since that's the case, then come in, "the Black Scaled Great Snake said, opening its mouth wide.

"It stinks. Do you want me to go into your mouths?" Shiyu asked helplessly.

"Yes, whether you enter his mouth or mine, you'll both end up in the same place. There's a seal inside, but you should be able to open it easily now, right?" the White Snake Sage explained.

"Alright. If you insist on making me go in, then I have no choice but to go in." Shiyu then controlled the Truth-Seeking Orb to wrap around his body, forming a thin outer membrane.

"He really is a clean freak." The White Snake Sage chuckled, Shiyu walked straight inside.

The Black Scale Immortal's body was filled with Natural Energy, but Shiyu was already doing well to avoid fainting, given that the smell inside was unbearable for humans.

The further Shiyu.

"Snake Sage Mode!" Shiyu finally transformed into the Snake Sage, and this part of his structure became more snake-like. He could no longer smell, since the sense of smell comes from the snake's tongue, while the nose is only used for breathing.

Shiyu finally reached a fork in the road, clearly a section of the White Phosphorus Snake's body.

Shiyu immediately ventured deeper into the area, but still found no boxes.

"How come there's a corpse here? Won't it dissolve?" Shiyu saw a corpse, but although it had become a dead body, it was still firm and uncorrupted.

"Byakugan!" Shiyu used his Byakugan to search around and finally discovered that the so-called seal was on the corpse's stomach.

"I wonder who this person is?" Shiyu then gently placed her hand on the man's abdomen, absorbing the mysterious man's bloodline power, and immediately sensed the seal within his body.

"Break!" Shiyu used his boundless chakra to break the seal, and Shiyu pulled a scroll from the man's abdomen.

"Finally found it. Luckily, I have the ability to teleport." Shiyu then appeared outside the two-headed serpent's body with a whoosh.

"I was just wondering whether I should open my mouth and let you out, but I forgot you can Teleportation," the Black Scaled Great Snake said.

"Did you get it, Snake Sage?" the White Phosphorus Snake asked.

The Snake Sage was naturally called Shiyu, Shiyu raised his hand and said, "Is this the right thing?"

"Impressive, you actually brought it out. You hid it so well; you must have had a lot of trouble." After saying this, the White Phosphorus Snake and the Black Scaled Great Snake transformed into human form.

They are two-headed snakes; when they transform into human form, one head is in front and the other behind. However, the one speaking now is mainly the White Snake Sage.

"Open it, this is the strongest Senjutsu among the three great immortal lands! Absolutely unique! And you are the most suitable person to learn it." The White Snake Sage said with some pride.

Shiyu was naturally very curious about the scroll, Shiyu after opening it, she let out a scream.

"Seriously! What an amazing Senjutsu! It's so perfect for me right now! This Senjutsu truly deserves to be called the strongest Senjutsu!"

Shiyu immediately asked, "White Snake Sage, tell me how to cultivate this level of Senjutsu?"

The White Snake Sage smiled and said, "Don't rush. To learn this Senjutsu, you need to first transform into Sage Mode."
