Summon the Villain: Marvel.

Elias' speed and strength put Black Widow and Hawkeye under great pressure. As soon as Black Widow swung her fist, Elias quickly dodged it and then his elbow hit Black Widow's chest with lightning precision. Black Widow groaned and was knocked back a few steps, with a painful expression on her face.

Seeing this, Hawkeye quickly attacked, and the long knife with a sharp sound of wind was aimed directly at Elias' face. Elias sneered, raised his hand to block easily, and then hit Hawkeye's abdomen with a knee strike. Hawkeye bent over in pain and almost lost his balance. He endured the pain and swung the knife to attack again, but Elias quickly dodged it. Elias backhanded a punch and hit Hawkeye's chin hard, knocking him back.

Seeing this, Black Widow quickly pulled out a tactical dagger from her waist, her eyes flashing with determination. She looked at Hawkeye and nodded. "Clint, we must work together. We can't let him defeat us one by one!" She whispered, her voice full of determination.

"Understood, Natasha." Hawkeye clenched the knife in his hand, stood firm, and his eyes were full of fighting spirit. They cooperated with each other and attacked Elias from different angles at the same time.

Black Widow and Hawkeye attacked from different positions. Black Widow attacked from the left side, and the dagger pierced Elias's ribs with a cold light. At the same time, Hawkeye swung his knife from the right side, aiming at Elias' neck. The two attacked at the same time like a storm, and they cooperated tacitly, leaving Elias almost no time to react.

Elias sneered, and dodged quickly like a ghost. His movements were light and flexible, and every sideways and backward movement was extremely accurate. He quickly shuttled between Black Widow's dagger and Hawkeye's blade, as if he was dancing a strange dance. Black Widow's dagger stabbed into the air, and Hawkeye's knife only grazed the corner of Elias' clothes, unable to touch his body at all.

"You two are really tenacious, but that's all." Elias' voice was filled with obvious sarcasm and disdain. "Do you think you can defeat me like this? That's just wishful thinking!"

Elias easily resolved the attacks of Black Widow and Hawkeye. They were anxious, but they had no intention of retreating. Black Widow quickly changed her attack method, and the dagger flexibly turned in her hand, stabbing, cutting, and slashing constantly, aiming at Elias's vital parts. Hawkeye mainly used powerful slashing, and each slash was full of power, trying to force Elias into a desperate situation.

Elias was able to handle the attack from both of them with ease, dodging quickly and accurately, as if he had anticipated their every move. His figure moved quickly in the air, easily avoiding the attacks from Black Widow and Hawkeye, and occasionally he chuckled, as if mocking their powerlessness and futility.

"Your cooperation is good, but it's in vain in front of me." Elias said coldly, with a playful gleam in his eyes.

Elias dodged the attacks of Black Widow and Hawkeye again. Black Widow's dagger missed, and Hawkeye's blade was also cleverly blocked by Elias. Elias seized this opportunity and counterattacked fiercely, hitting Black Widow's abdomen with a heavy punch, and then kicked Hawkeye with a roundhouse kick, sending him flying and falling heavily to the ground.

The two men lay on the ground, gasping in pain, their bodies covered with bruises and scars. Elias stood in front of them, with a cruel smile on his face and a gleam of disdain in his eyes.

Elias, through the fierce battle with Black Widow and Hawkeye, keenly realized that they had also been injected with some kind of genetic drug. He couldn't help but reveal a mocking smile, his eyes full of disdain and contempt.

"Heh, you two little mice were actually injected with genetic drugs. However, those junk and outdated drugs you injected are not worth mentioning at all." Elias sneered, his tone full of ridicule and contempt, "It seems that you are just cannon fodder sent by some small organization. You dare to challenge me? You really overestimate your own abilities."

He slowly approached the fallen Black Widow and Hawkeye, with a cruel smile on his face, "Now, I will end your lives with my own hands and let you know what true power is."

Just as Elias was about to launch a fatal attack, there was a sudden sound of breaking through the air in the sky. A figure fell from the sky and landed heavily on the ground with a loud bang. It was Captain America, his shield flashing with dazzling light, standing firmly in front of Black Widow and Hawkeye, blocking Elias' attack.

"Natasha, Clint, are you okay?" Captain America asked with concern, his eyes full of worry and determination.

Black Widow and Hawkeye struggled to get up from the ground, looked at each other, and smiled bitterly. "Steve, you're here at the right time." Black Widow panted.

Hawkeye also nodded and said with a smile: "Captain, we were just warming up just now. I didn't expect you to come to the rescue so soon."

Captain America smiled slightly, with a hint of relief on his face, "Sorry, I'm late. I had a little trouble on the road just now, but it's okay now."

Black Widow and Hawkeye couldn't help but smile with relief when they heard Captain America's humorous explanation. With the captain's joining, their chances of winning were greatly increased.

Elias saw the iconic Captain America and immediately understood who he was facing. His face turned gloomy, but then he sneered, "The Avengers? What a big event. But you are destined to be unable to stop me today."

He decided to retreat because he knew that they had not found out anything useful and he could always destroy the place to ensure the secret was not leaked.

Captain America saw that the other party was about to retreat, so he took action immediately. He rushed forward suddenly, the shield in his hand flashing coldly, and rushed straight towards Elias.

Elias was extremely fast. He rushed forward and his fist hit Captain America with a fierce sound of wind. Captain America quickly raised his shield to block the attack, but the strong impact made him step back a few steps. He quickly adjusted his posture, his eyes calm, and predicted Elias's next move in advance.

Elias attacked again, his fist as fast as lightning, aiming at Captain America's side. With years of combat experience, Captain America quickly dodged and hit Elias with a backhand shield strike, forcing Elias back. Then, Captain America spun low, blocked Elias's continuous attacks with his shield, and found the right time to punch Elias in the chest.

The two fought fiercely on the battlefield, with fists and feet intersecting and the sound of metal colliding. Elias's attack was swift and fierce, but Captain America relied on calm judgment and precise defense to continuously resolve the opponent's offensive. He predicted the opponent's movements in advance and made defensive moves, and each time he did it accurately.

Elias' eyes flashed with ruthlessness. He knew that if he continued to fight, he would probably be dragged into a protracted war, which would be detrimental to the Leviathan Group's plan. He decided to retreat temporarily.

"You are lucky today, but you won't be so lucky next time." Elias said coldly, then suddenly jumped up and his body quickly disappeared into the darkness.

As Elias retreated, a sharp alarm suddenly sounded in the hidden manufacturing plant of the Leviathan Group. The red warning lights kept flashing, and a sense of urgency filled the air. Black Widow quickly stood up from the ground, and looked around vigilantly, and found that white smoke began to emerge from every corner of the factory, and it was obvious that the self-destruct program had been activated.

"Everyone, hurry up! The factory is going to explode!" Black Widow shouted loudly, and she quickly ran towards the exit.

Captain America and Hawkeye followed closely behind, knowing that they had to leave here as soon as possible, otherwise they would be trapped in the ruins of the explosion. As they ran, various equipment inside the factory began to emit a harsh roar, the huge machines began to vibrate, and the ground began to tremble.

"Natasha, ahead!" Captain America noticed that a steel gate in front of him was slowly closing. He quickly rushed forward and pushed the gate open to buy time for Black Widow and Hawkeye to pass through.

Black Widow and Hawkeye quickly passed through the gate, followed by Captain America. As soon as they passed through, the steel gate slammed shut, and a huge crash echoed behind them. The three continued to run, and the explosions inside the factory were getting closer and closer, and the air was filled with hot flames and thick black smoke.

Hawkeye coughed hard, his face covered with sweat and dust, "Captain, we must find a faster way, otherwise we will be trapped here!"

Captain America nodded quickly, looking around. He saw a ventilation duct not far away. The entrance of the ventilation duct was half open, and gusts of cool wind came from inside. "Over there, the ventilation duct!" He pointed in the direction of the ventilation duct and said loudly.

Black Widow rushed to the ventilation duct without hesitation. She turned over and crawled in nimbly, followed by Hawkeye and Captain America. The ventilation duct was narrow and dim, but they didn't care about that and quickly crawled towards the exit outside. Their rapid breathing and explosions in the distance echoed in the duct, and the whole factory seemed to collapse at any time.

"Hurry up, the exit is just ahead!" Black Widow reminded loudly, her voice carrying a hint of nervousness, but more of determination and courage.

They sped up and finally saw a small exit at the end of the ventilation duct. Black Widow was the first to get out of the ventilation duct, followed by Hawkeye, and Captain America was the last to get out of the ventilation duct. They stood up quickly and found that they had left the core area of ​​the factory, but the danger was not over yet.

"Follow me!" Black Widow led the way to an abandoned corridor with an emergency exit at the end. She pushed the door of the emergency exit open with force, and the cold wind mixed with the night air hit her face. She quickly called Hawkeye and Captain America to go through the emergency exit.

The three rushed out of the emergency exit and stood in an open space outside the factory, with the factory building gradually collapsing behind them. Explosions continued, and the flames reflected in the night sky, like a doomsday carnival. Black Widow, Hawkeye, and Captain America stood in the open space, their faces covered with sweat and dust.
