Summon the Villain: Marvel.

Elias felt the calmness gradually returning to his body and exhaled gently. He turned and walked to a mirror in the safe house and changed into a neat suit. The black suit made him look even more cool and elegant. He adjusted his tie slowly and calmly, as if the fierce battle that had just happened had not left any trace on him at all.

"Heh... it's just a small episode." He muttered to himself in the mirror, a faint sneer appeared on the corner of his mouth, and a dangerous light flashed in his eyes. He felt the strength in his body gradually stabilized, and the feeling of almost collapsing before was completely suppressed.

Elias regained his elegant posture and walked out of the safe house. The outside world was still silent, as if everything was waiting for something to happen.

"Hmm..." Elias whispered to himself, sensing something unusual about his surroundings. He stood in an empty alley, surrounded by a deathly silence, even the wind seemed to have stopped.

At this moment, a deep voice suddenly broke the silence: "This is our goal."

Elias's eyes suddenly turned to the direction where the voice came from. He saw four strangely dressed figures slowly walking out of the shadows. The leader was a white-haired masked man with a forehead protector on his right eye, and a calm and cunning light in his left eye. The three people standing beside him had their own characteristics: a blond boy wearing an orange combat uniform with a defiant look; a black-haired boy with cold and proud eyes; and a pink-haired girl with a firm look in her eyes.

The white-haired man pointed at Elias and said to the three people beside him: "This is our mission target this time. Be careful, he is not an ordinary enemy."

"Humph, this guy doesn't look special." Naruto scratched his head nonchalantly, with a disdainful expression on his face, but a hint of seriousness in his eyes. He clenched his fists, and his voice was filled with eager anticipation: "Okay, let's defeat him quickly! I want to take advantage of the one week given by Lord Orochimaru to travel around this world. Kurama has started to urge me, and he will get angry if I don't take action!"

Sasuke looked at Naruto coldly, his tone full of arrogance and disdain: "Naruto, don't be so impatient. It won't take much time to deal with such a weakling."

"Stop talking nonsense!" Naruto turned around and shouted, but there was obviously no extra expression on his face, as if he was already accustomed to Sasuke's provocation.

Sakura stood aside, sighed helplessly, and clenched her fists: "Please, you two, don't quarrel at this time! Concentrate on dealing with the enemy in front of you."

Facing these unexpected enemies, Elias' expression did not waver at all. His eyes were cold as he swept across the four people in front of him and said calmly: "No matter who you are or where you come from, since you are standing in my way, there is only one outcome - death."

His voice was low and cold, with unquestionable killing intent. As the words fell, his figure suddenly accelerated, and he rushed towards Naruto like a black lightning. The air seemed to be torn apart, with an endless sense of oppression.

"Do it!" Kakashi's eyes narrowed slightly and he gave the order instantly. The three ninjas quickly took up fighting stances, ready to face this duel across time and space.

Naruto, Sasuke and Sakura exchanged glances quickly, and understood each other. They immediately entered into combat mode according to the tactics taught in the Ninja School and the Umbrella New Rules Manual. The triangle formation was deployed, with Naruto standing in the front, Sasuke and Sakura on both sides, forming a perfect encirclement.

"Sasuke, Sakura, follow the plan!" Kakashi commanded calmly from behind. He knew that this opponent was unusual and he had to be careful.

Naruto clenched his fists, his eyes sparkling: "Let's test his strength first, and then find an opportunity to defeat him in one fell swoop!"

Sasuke nodded calmly, the Chidori in his hand flashing with a faint electric light: "Don't be careless, Naruto, this guy doesn't look easy to deal with."

Sakura formed seals with her hands, ready to provide support at any time: "I will support you from the rear, stay safe."

Elias stood opposite, staring coldly at the three young men who suddenly appeared. He didn't know them, but from their positions and momentum, he felt a force that should not be underestimated. His body began to harden, his muscles tensed, ready for battle.

"Come on, let me see what you are capable of." Elias sneered, his voice full of contempt.

Naruto took the lead in attacking. He quickly formed a seal and several shadow clones appeared instantly, rushing towards Elias in unison. "Multiple Shadow Clone Technique!" He shouted, and all the clones attacked at the same time, trying to disrupt the opponent with the advantage of numbers.

Elias looked at the swarming Naruto clones without fear. His body suddenly accelerated, turning into a black shadow, shuttling between the clones. Every punch he threw was powerful, defeating one clone after another. The "bang bang" sound of the clones disappearing echoed in the air.

"This little trick won't work on me!" Elias said coldly, his eyes locked on the real Naruto.

At this moment, Sasuke launched an attack from the flank. His hands shone with blue electric light, and his speed was as fast as lightning: "Chidori!"

The lightning cut through the air and headed straight for Elias's side. Sensing the danger, Elias turned around immediately, his arm quickly hardened, and he blocked Sasuke's Chidori. The strong current surged through his arm, but failed to break through his defense.

"Interesting." Elias raised his eyebrows slightly, and with a sudden increase in strength, he punched Sasuke back. Sasuke flipped in the air and landed steadily, his brows furrowed.

"Sakura, now!" Naruto shouted.

Sakura was already prepared. She gathered powerful chakra in both hands and punched the ground fiercely: "Strange force - Earth crack!"

The ground instantly cracked under her fist, and huge cracks quickly spread towards Elias. Elias's feet sank and his body was slightly unbalanced.

"Good opportunity!" Naruto formed a seal again, and a huge Rasengan formed in his hand. The blue energy ball emitted a dazzling light: "Rasengan!"

He rushed towards Elias quickly, and the Rasengan hit his opponent's chest. Elias' eyes flashed with a fierce light, and his chest instantly hardened, facing the Rasengan. The two powerful forces collided with each other, erupting an astonishing shock wave, and the glass of the surrounding buildings shattered.

"What!" Naruto felt an irresistible rebound force and was knocked back several steps.

Elias stood there unharmed, with a sneer on his face: "Your attack is too weak, it can't hurt me at all."

Sasuke was not willing to be outdone. He quickly formed seals with his hands, and the Sharingan in his eyes flashed red: "Fire Style: Great Fireball Technique!"

A huge fireball spewed out of his mouth, and the scorching flames completely enveloped Elias. The firelight shone on everyone's face, and the heat wave hit them.

However, Elias's indifferent voice came from the flames: "A mere flame can't do anything to me."

The flames gradually dissipated, and Elias's body was covered with a layer of silver luster, as if it was made of steel. His body's hardness increased again, completely resisting Sasuke's fire escape attack.

Sakura quickly stepped forward and stood side by side with Naruto and Sasuke: "His defense is too strong, we must find his weakness!"

Naruto clenched his fists, his eyes determined: "Then use a stronger attack!"

Sasuke nodded, "That's right, attack together and focus on breaking through his defenses."

Elias watched their discussion with cold eyes, feeling impatient. His body suddenly began to grow in size, and the muscles in his right arm expanded rapidly, becoming like a boulder. He swung his hand violently, and his huge fist, with a fierce airflow, rushed straight towards the three people.

"Get out of the way!" Kakashi warned from behind.

The three of them quickly dispersed, and their huge fists smashed into the ground, instantly forming a deep pit, with gravel flying everywhere. The power of Elias's attack was so great that it made them wary.

"His strength and speed are beyond ordinary people, be careful!" Kakashi warned.

Naruto gritted his teeth and formed a seal again: "Multiple Shadow Clone Technique!"

Dozens of Naruto clones appeared again and surrounded Elias. They held the Rasengan in their hands at the same time, forming a huge attack formation.

"I won't let you block it easily this time!" Naruto roared, and all his clones attacked at the same time.

Elias's eyes focused, and his body spun rapidly, forming a strong cyclone. The power of the cyclone scattered the clones around him one after another, and the energy of the Rasengan was weakened in the cyclone, unable to cause any substantial damage to him.

Seeing this, Sasuke immediately activated the higher form of Sharingan, and the Chidori in his hand turned into a more powerful lightning blade: "Naruto, cover me!"

Naruto understood Sasuke's intention and created another shadow clone to try to interfere with Elias's vision. Sakura gathered chakra on the side, ready to support at any time.

Sasuke approached Elias at an extremely fast speed, with lightning dancing in his hands and making a sharp thunderous sound. He aimed at Elias's left leg, which had not been hardened before, and stabbed it suddenly.

"Chidori-ryu!"

This time, Elias failed to fully defend himself, and his left leg was hit by Chidori, and blood splattered instantly. A trace of pain flashed across his face, but was quickly replaced by anger.

"Damn bugs!" Elias roared, and his body changed again. His wounds healed quickly, and the muscles in his left leg swelled and his strength increased greatly. He kicked out fiercely, and Sasuke had no time to dodge and was hit directly in the abdomen. The whole person was kicked dozens of meters away and hit heavily against a big tree.

"Sasuke!" Sakura exclaimed and immediately rushed to Sasuke's position to check his injuries.

Naruto was furious when he saw his friend injured. The Nine-Tails' chakra began to stir in his body. His eyes gradually turned red and fox patterns appeared on his face.

"You dare to hurt my friends, I will never forgive you!" Naruto's voice was filled with a low growl.

Elias sensed the powerful chakra fluctuations from Naruto and frowned slightly: "This power..."

Naruto no longer hesitated, the Nine-Tails' chakra bursting through his body, a red energy coat covering his entire body, and he rushed towards Elias with a new level of speed and strength.

The two men exchanged blows in an instant, punching each other and creating shockwaves. Elias felt unprecedented pressure, and his steel body began to crack under the attack of the Nine-Tails' chakra.

"How is this possible!" Elias looked at his damaged body in disbelief.

Naruto seized the opportunity and formed a larger Rasengan with his hands: "Super Large Rasengan!"

The huge energy ball with destructive force hit Elias directly in the face. Elias quickly steeled his whole body to try to resist this fatal blow.

"Go to hell!" Naruto roared, and the Rasengan hit Elias hard.

A huge explosion resounded through the sky, shock waves swept all around, smoke and dust rose up, and the entire ground was lifted up, forming a huge deep pit.

Kakashi quickly stepped forward and protected the injured Sasuke and Sakura behind him to prevent them from being hurt by the aftermath.

The smoke gradually dissipated, and Naruto stood there panting, his eyes fixed on the front. His Nine-Tails chakra began to weaken, and his physical strength reached its limit.

"Is it over?" Sakura asked worriedly.

However, a deep laugh was heard in the smoke and dust. Elias' figure gradually appeared. Although his body was covered with cracks and blood, he was still standing.

"You guys...are good." Elias' voice was filled with madness, "But it's not enough!"

His body changed again, his wounds healed at a speed visible to the naked eye, and his strength seemed to be even stronger than before.

Naruto's eyes widened in disbelief, "How can he still stand up?"

Sasuke barely supported his body and analyzed calmly: "His regeneration ability is too strong. He must be completely defeated in one blow."

Kakashi stepped forward, a look of determination in his eyes: "Looks like we have to use that."

Naruto and Sasuke looked at Kakashi at the same time and nodded.

"Raikiri!" Kakashi gathered powerful lightning power in his hands, and the lightning illuminated the entire battlefield.

Sasuke also gathered his Chidori once again, while Naruto focused all of his remaining chakra.

"Three people attack together!" Kakashi ordered.

The three chakra powers merged together to form an extremely dazzling beam of light, which hit Elias directly. Elias felt an unprecedented danger and tried to escape, but it was too late.

"It's over!" the three shouted in unison.

The power of thunder and lightning penetrated Elias' body, and his steel defense completely collapsed in front of this force. Huge energy exploded in his body, bringing devastating damage.

Elias' body was blown away by the huge force and fell heavily to the ground, unable to stand up again.

Naruto, Sasuke, Sakura and Kakashi stood together, supporting each other. Their strength was exhausted, but they finally defeated the powerful enemy.

"We... won." Naruto gave a tired smile.

Sasuke nodded, a glint of recognition in his eyes, "This was a good collaboration, Naruto."

Sakura breathed a sigh of relief and smiled, "I'm glad everyone's okay."
