Start with the Mangekyō and leave Konoha with Madara.

"Humph, I am not a dishonest snake!"

Xinya shook his head proudly, then slowly crawled in front of Shenyu and opened his mouth to spit out a huge green scroll.

The scroll was more than two meters high and covered with translucent saliva. It fell to the ground with a "bang". Xinya spit out the scroll and opened it very flexibly, slowly unfolding it in front of Shenyu.

"As long as you write your name here and put your fingerprint on it with blood, you will have successfully signed a contract with me."

"So particular?" Shen Yu looked at the contents on the scroll. The runes were complicated and obscure, and many snake-like patterns were engraved in an orderly manner, faintly revealing a powerful contract power.

During the years in Uzushio Village, he was exposed to many sealing techniques. Although he could not be said to have been immersed in the art for many years, he knew a thing or two, including the contract seal.

Judging from the aura on the scroll, a simple "contract seal" would be unable to do anything to a psychic contract of this level.

"Of course, I come from Longdi Cave, one of the three great immortal places. I am the strongest ninja snake in the cave besides the White Snake Immortal!"

Xinya raised his head proudly, his tone filled with arrogance that looked down on the world, as if the snake that had just been pinned to the ground by the two wooden dragons was not him.

"As a ninja beast with a formal organization like us, we have to be extremely cautious when signing a contract. If you can't get our approval, you want to establish a relationship with Ryuchi Cave? No way!"

"Yes, yes, that's great." Shen Yu said perfunctorily and waved his hand, "Sign it."

Orochimaru behind him nodded immediately, gently placed the Uzumaki clan member who was sandwiched between his ribs on the ground, walked briskly to the huge contract scroll, and raised his hand to bite his fingers.

"Hey?"

Xinya narrowed his eyes vigilantly, spit out his tongue and blocked Orochimaru's way, preventing his next move.

"What does it mean?"

"What do you mean?" Shen Yu was also stunned for a moment, and raised his eyes with a little confusion, "Sign a contract?"

Xinya lowered his head, looked at Shenyu, then looked at Orochimaru, and then asked belatedly, "With him?"

"Of course, why not follow me?" Shen Yu shrugged, "I already have a spirit beast, so I don't need it right now."

Xinya was completely dumbfounded. It was the first time that Shenyu saw the emotion of "confusion" on the face of a giant snake.

"No..." It opened its mouth and first carefully looked at Orochimaru from head to toe, its pupils flashing with undisguised disdain, "With this kind of strength and this level of chakra, how can you be worthy of being my companion, Shinga the Great Snake?"

"Do you want to break the bet?" Shen Yu's tone gradually became low and he began to roll up his sleeves.

"No... no, this is different from what we agreed on..." Xinya shrank his neck humanely, and Xinzi vomited wildly, "I thought the contract was signed with you, so I agreed..."

"Hurry up and sign, otherwise it won't be as simple as killing a snake." Shen Yu clenched his fists, "Maybe I'll get excited and go to Longchi Cave to send you, a group of ninja snakes, down to reunite!"

"You...you are too extreme..." Xinya's voice trembled slightly. Suddenly, he seemed to think of something, and his pupils lit up slightly, "Longdi Cave, yes, you can take him to Longdi Cave!"

"So you have made up your mind not to sign?" Shen Yu looked at Xin Ya as if he were an idiot. "Are you crazy? I will kill you before I go to Longdi Cave. You are dead no matter what."

"Huh? That's not what I meant!" Xinya explained quickly, "It's not that I can't sign, but I'm worried that if the news of me casually accepting an unknown kid as my master gets out, I'll be laughed at by other snakes..."

Xinya suddenly pinched his throat and imitated a shrill voice: "Look, look, Xinya, the most violent snake in Longdi Cave, actually recognized his master casually today..."

"With this, you are still worthy of being the most powerful snake. You really don't have the face of a snake..."

Seeing that Shen Yu's face was visibly getting gloomier, Xin Ya immediately said, "I suggest that you take him to Longdi Cave. If he can pass the three tests set by the White Snake Immortal, then there will be no problem, and I won't have any trouble in this regard."

"Don't think it's troublesome. If he really passes the test, the White Snake Immortal will personally teach him to practice the magic of Longdi Cave!" it added.

Shen Yu stroked his chin, looking thoughtful, "Is it a fairy technique?"

Xinya silently put away the scroll and swallowed it back.

"Senjutsu, I heard that this is the fundamental difference between the summoned beasts of the three holy places and other ninja beasts!" Uzumaki Haruna on the side couldn't help but speak, her eyes full of surprise.

"What if I fail?" Shen Yu looked up and asked.

"Even if it doesn't pass... I won't refuse to sign. I'd rather accept defeat than be looked down upon by you humans!" Xinya snorted coldly.

"What do you think?" Shen Yu looked at his disciple with a gentle gaze.

Orochimaru took a deep breath, his eyes firm, "Master, I'll be fine. If I can't pass the test, I won't make it difficult for Xinya. I will keep moving forward until the day I get its approval!"

"Hmm?" Xinya looked at the boy with some surprise. She didn't expect him to be so principled.

"Then it's decided. After we finish dealing with things here, you will lead us to Longdi Cave." Shen Yu clapped his hands, "In the meantime, just follow us obediently."

"Of course." Xinya raised her head.

Shen Yu smiled softly, "It's just that... your size is a little too eye-catching. I have a spiritual beast that can change its size at will."

"Tsk, that's bullshit!"

Xinya growled defiantly, and his huge body like a mountain began to shrink. In just a few breaths, he turned into a small red snake the size of a normal viper.

It stuck out its tongue, twisted its body without any hesitation, climbed up Shen Yu's legs, and coiled its snake body into several circles and wrapped around his shoulders.

"Changing shape is just one of my many magical powers." After Xinya said this, he stood still like a decoration.

Shen Yu blinked at Orochimaru, "It seems... this guy doesn't really approve of you now."

"I will prove my worth." Orochimaru stared at Shinga with burning eyes and clenched his fists at his sleeves.

"Next..."

Shenyu stretched out his hand towards the unconscious Uzumaki tribe member, and a warm and soft green light enveloped the two of them. Under the nourishment of pure vitality, their faces gradually turned rosy and their eyelids trembled as they opened.

The two of them sat up straight and looked around at the unfamiliar environment, both of them looked confused.

Seeing this, Haruna immediately trotted over and explained the whole story to her companions. The two of them immediately looked at Kamiya and Orochimaru with gratitude.

"Let's go, to the Whirlpool Country."

"Wait!" Haruna suddenly called out to Shenyu, pinched his sleeves with her two small hands, and said embarrassedly: "Master Shenyu, we haven't completed the mission yet?"

"Mission?" Orochimaru asked, "You mean the mission to find information about your missing companions?"

Haruna blushed, "Yeah! To be honest, we just arrived in the Rain Country and haven't seen the missing tribesman yet, but we were attacked by the Sand Ninja..."

"Well, I'll go with you guys."

Shen Yu shook his sleeves, and a burst of black gas floated up, wrapping everyone in it. It then turned into a huge four-handed giant. He bent his knees slightly and jumped out of the sand pit with several people in one step.
