Summon the Villain: Marvel.

In the world of Naruto, River Country, the black market.

In a dark underground exchange, the lights were dim and the air was filled with a mixed smell. Kakuzu and Hidan were accepting missions here. Kakuzu was as calm as ever, standing proudly in front of the mission board, carefully selecting the missions. His eyes were cold and sharp, as if he could see through the value of every mission.

Hidan seemed a little impatient. He looked around anxiously and joked to Kakuzu from time to time: "Hey, Kakuzu, what mission are you choosing? Is there anything here worth taking?"

Kakuzu glanced at Hidan and said coldly, "Shut up, just follow my instructions."

Hidan curled his lips, looking somewhat dissatisfied, but knowing Kakuzu's character, he said nothing more. The two of them stood in front of the mission board in the black market, and the whispers around them gradually reached their ears.

"I heard that the Sand Ninja is preparing to take part in Konoha's Chunin Exams. It's going to be a big event."

"Yes, they have made a lot of preparations and even improved the electricity usage there."

"Electricity situation? Hasn't the Wind Country always been short of water and electricity?"

"Hehe, you may not know that although the streets of Wind Country are still hot and humid, the indoor air conditioning and electricity system have perfectly solved this problem. I heard that the daimyo and wealthy businessmen of Wind Country are buying air conditioners that are very energy-saving, safe and easy to use."

Kakuzu frowned slightly, obviously interested in this information. Hidan said impatiently, "Air conditioning? Those guys really have too much money to spend."

Kakuzu ignored Hidan's ridicule and continued to listen to the conversations around him. He knew that this information might be of some help to their mission.

"I heard those air conditioners use a new technology, I don't know where it came from."

"Yes, I heard that this technology is not only energy-efficient, but also extremely safe and reliable. Now the electricity consumption situation in the entire Wind Country has been greatly improved."

Kakuzu secretly took note of this information. He knew that there might be some secrets behind these changes. Perhaps these new developments of the Sand Ninja and the Wind Country were worth their in-depth investigation.

"Let's go, Hidan, we have a new target." Kakuzu said calmly, turning and walking towards the exit of the black market.

Feidan was stunned for a moment, then smiled: "Oh? A new target? Looks like there's something interesting to watch."

After walking out of the black market, Hidan looked at Kakuzu with a puzzled smile on his face: "Hey, Kakuzu, what mission did you accept this time?"

Kakuzu calmly replied, "To kill a bandit named Jie, he is on a small hill in Kawa no Kuni. We will be there by midnight."

After hearing this, Feidan curled his lips in disdain: "Bandit? What strength does that guy have? Is it enough for me to sacrifice to the evil god?"

Kakuzu glanced at Hidan and continued, "Based on the description of the mission, he's probably as strong as an elite jonin. The reward will be very generous."

A hint of excitement flashed in Hidan's eyes, and a wicked smile appeared on the corner of his mouth: "The strength of an elite jonin? That's quite interesting. The evil god will definitely be very satisfied."

Kakuzu nodded slightly and analyzed calmly: "This Jie should not be an ordinary bandit. The strength of an elite jonin is very rare among bandits. There may be some chunins and genins under him, or even former rebels from a certain village. This mission may be a bit troublesome, but the reward is indeed worth it."

Hidan waved his hand nonchalantly, "What's the trouble? We are the 'Immortal Duo'. Those so-called elite jonin are just good materials for sacrifice."

Kakuzu smiled coldly and continued, "Don't be careless, Hidan. We need to be fully prepared. This mission may be more complicated than we think."

"Tsk." Although Hidan said he didn't care, he still trusted Kakuzu's judgment in his heart. They walked towards their destination.

The lights of the black market gradually disappeared behind them, and the figures of the two people looked particularly gloomy in the moonlight.

"I hope this mission will allow me to kill as much as I want." Feidan muttered to himself, with a fanatical light flashing in his eyes.

......

At midnight, the immortal duo finally arrived at their destination.

The moonlight was like silver, shining on the few places of human habitation on the hillside, making it seem particularly peaceful. However, Kakuzu felt a sense of uneasiness in his heart.

Kakuzu stood at the foot of the hill, observing the surrounding environment carefully, frowning slightly. His intuition was always very accurate, and it was with this keen intuition that he was able to achieve a "brilliant" record in his fight with the first Hokage. At this moment, this intuition told him that there was a great danger hidden ahead.

Hidan, on the other hand, had an impatient look on his face. His eyes were blazing with desire for blood and killing. "Kakuzu, what are you hesitating about? If you don't take action now, the evil god will not be happy!"

Kakuzu ignored Hidan's urging, he was still analyzing calmly: "We can't act rashly, there may be an ambush here. We must formulate a thorough battle plan."

However, Hidan obviously didn't have the patience to listen to Kakuzu's analysis. He could no longer suppress the murderous intent in his body. He looked up to the sky and laughed wildly: "Ha! Planning is the most annoying thing. I just want to kill to my heart's content!"

After saying that, Feiduan rushed directly to the hillside, the sickle in his hand flashing with cold light, and he shouted: "Zhe! I want to dedicate your blood to the evil god!"

Kakuzu shook his head helplessly. Although he was troubled by Hidan's recklessness, he also knew Hidan's fighting ability. Hidan's fearlessness and madness could often create unexpected results. So Kakuzu followed closely in Hidan's footsteps, his eyes calm and sharp.

"The two of us can't beat an elite jonin?" Kakuzu couldn't help but feel a little doubtful. He glanced at Hidan who had already rushed up the hill, and an ominous premonition rose in his heart.

At this moment, Kakuzu suddenly felt a strong murderous aura behind him. He reacted quickly, turned around and punched back. The strong collision sound echoed in the night sky. Kakuzu took a few steps back, and the black shadow in front of him gradually appeared. He looked carefully and saw a masked man standing in front of him, wearing a black ninja outfit and a slender figure.

"Robbery?" Kakuzu asked tentatively, his eyes fixed on the other person, his mind filled with extreme alertness.

Jie's clothing exudes a mysterious and deadly aura. His mask covers his face, leaving only his cold eyes. His equipment is sophisticated and sharp, with several sharp ninja swords hanging around his waist, each of which looks so dangerous and deadly.

On the other side, Feidan had already rushed into the camp on the hillside, and just as he was about to swing his sickle, blood splattered everywhere.

A young man suddenly appeared in front of him.

"What the hell?" Feiduan stopped and looked at the boy in front of him. There was a hint of disdain and curiosity in his eyes.

Kimimaro stood there quietly, wearing a white robe, with a stern face, bone spurs sprouting from his fingertips, emitting a cold light. His eyes revealed a stern murderous intent.

"Do you want to die?" Kimimaro said coldly, with an unquestionable majesty in his voice.

Feiduan sneered disdainfully, with a hint of arrogance on the corner of his mouth: "You are my opponent? Haha, that's great, I can just offer your blood to the evil god!"

Kimimaro's eyes became even colder. He slowly raised the bone spur in his hand and said in a cold tone: "Today, you will be my sacrifice."

The fighting atmosphere on both sides suddenly became tense. Under the night sky, Kakuzu and Zed, Hidan and Kimimaro, each stood on the opposite side of the field, and murderous aura filled the air.

......

Kimimaro recalled his experience a few days ago. He was brought to a whole new world by Orochimaru. That place was technologically advanced, full of complex equipment and unfamiliar environments that he could not understand. He was placed in a bright and clean laboratory, and next to him stood a gentle but cold lady, Irene.

After lying down, Irene smiled and said to Kimimaro: "This is a special genetic fluid that can fully stimulate your potential." Her words were gentle, but with unquestionable authority. An arm with many parts appeared, and Kimimaro felt a tingling pain. The syringe injected the mysterious liquid into his body.

As time went by, Kimimaro felt a dramatic change in his body. His body, which had been weak due to illness, gradually became stronger, and his cells seemed to be full of endless vitality. He felt that every cell in his body was glowing again, as if the flame of life had been rekindled.

"This power..." Kimimaro murmured to himself, feeling the power surge in his body, a feeling of fullness he had never experienced before. His bones became harder, and his body's recovery and reaction speed were significantly improved.

After the memory ended, Kimimaro's gaze returned to the enemy in front of him, Hidan, and a sneer appeared on his face. He knew that he was no longer the sick boy in the past, but a truly powerful "warrior".

"Come on, let me see your strength." Kimimaro whispered, the bone spur in his hand flashing a cold light. He was ready to face this battle, with a firm belief in victory in his heart.

There was a fanatical light flashing in Feidan's eyes. He raised the three-bladed sickle high and rushed towards Kimimaro with a wild laugh: "Hahaha, let me see how much blood you can sacrifice to the evil god!"

Kimimaro sneered, and the bone spur in his hand quickly took shape. His eyes were cold and focused: "Then give it a try."

The two men clashed in an instant, the sickle and the bone spur collided in the air, making a metallic "clang" sound. Feidan's attack was fierce and crazy, and the three-bladed sickle in his hand swept towards Kimimaro like a storm. Kimimaro was as steady as a mountain, swinging the bone spur quickly and accurately blocking every blow.

"Clang! Clang! Clang!" The sickle and the bone spurs kept colliding, sparks flying. Kimimaro's every defense was extremely accurate, as if he could foresee every move of Hidan. And Hidan forced his opponent into a desperate situation with his fanatical attack intention.

"You are such a troublesome guy!" Feiduan gritted his teeth and suddenly increased the speed of his attack. The three-bladed sickle drew blood-red streaks in the air.

"Dang!" Kimimaro's bone spur once again accurately blocked Hidan's attack. With a flick of his hands, the bone spur struck back like lightning. Hidan was caught off guard and his shoulder was cut by the bone spur, and blood splattered instantly.

Instead of feeling scared, Hidan became even more excited: "What a great feeling! Come again!"

Kimimaro's expression remained stern, he knew that he couldn't let his guard down. According to the intelligence, Feidan had irrational madness and immortality, he knew that this battle would never be easily resolved.

But it is precisely because of this that we can live up to the "cultivation" of Master Orochimaru.

"Clang clang clang--" The two continued to fight fiercely, the sickle and the bone spur kept colliding in the air, and the sound echoed in the valley like thunder. Feidan's attack became more and more violent, and Kimimaro's defense became tighter and tighter. Every time he counterattacked, he was aimed at Feidan's vital points.

A flash of madness flashed in Hidan's eyes. He suddenly jumped up, raised the three-bladed sickle high, and slashed at Kimimaro. Kimimaro's eyes turned cold, and the bone spur flew up into the air, instantly blocking Hidan's attack. The weapons of the two intertwined and collided in the air, making a deafening noise.

“Bang!” Feidan was knocked back a few steps by Kimimaro’s power, but he still stood firm, with a bloodthirsty smile on his face: “You are very strong, but I will make you bleed more!”

Kimimaro snorted coldly, and the bone spur in his hand flashed with a cold light: "Then give it a try."
