Marvel: Ancient One comes to visit, can Xiang Lei protect him?

Lin Feng clenched his weapon tightly and locked his eyes on the enemies. He took a deep breath and made a gesture, signaling his teammates to prepare for the attack.

"Action!" Steve gave the order, and the Avengers quickly launched their attack. Lin Feng rushed towards the enemy like a cheetah, and the enemies fell one after another in the flash of swords and sabers.

The battle was extremely fierce. Although the Hydra soldiers were well-equipped, they were defeated by the powerful offensive of the Avengers. Lin Feng was very good at fighting in the melee, and every move was full of deadly precision.

At this moment, a flash of light caught Lin Feng's attention. He turned around and saw a figure running away to the depths of the underground hall. Lin Feng's heartbeat suddenly accelerated, as that figure reminded him of his sister.

"I have to catch up with him!" A thought flashed through Lin Feng's mind, and he quickly rushed towards the figure, his steps as light as the wind.

Deep in the underground hall is a long and narrow passage, with various complex instruments and equipment on both sides. Lin Feng followed the figure closely, with complex emotions surging in his heart. He vaguely felt that this figure might be related to his sister's whereabouts.

At the end of the passage was a secret room. Lin Feng rushed in and found the figure standing in front of a console, seemingly activating some device. A cold light flashed in Lin Feng's eyes, and he quickly rushed over.

"Stop!" he shouted, and the blade slashed towards the figure's wrist like lightning.

The figure cried out in pain, and the device in his hand fell to the ground. He turned and looked at Lin Feng, revealing a strange and pale face.

"Who are you?" Lin Feng asked coldly.

Lin Feng stared at the strange face, and a complex emotion surged in his heart. The face was pale and terrified, but there was a mad light flashing in the eyes. He felt that every nerve in his body was tense, and his heartbeat was like a drum.

"Who am I? This is not your concern." The man sneered, with a hint of sarcasm and contempt in his voice, "You will never understand our great plan."

"Hydra's plan?" Lin Feng asked coldly, his hand still tightly holding the knife, the sharp blade flashing in the dim light.

"You Avengers people will never be able to stop us." The man glared at Lin Feng, his eyes full of hatred and contempt.

"We will stop you." Lin Feng said calmly, with a determined fire burning in his eyes, "And I will definitely find my sister."

The man was stunned for a moment, then burst into laughter, "Your sister? Hahaha, your sister has already become our experimental subject, maybe she doesn't exist now."

This sentence was like a sharp blade, piercing Lin Feng's heart. His face suddenly darkened, and the anger in his heart was instantly ignited. He punched the man in the face and roared, "What did you say?!"

The man stumbled back with a painful expression on his face, but he was still laughing crazily, "You will never find her, she has disappeared from this world!"

Lin Feng's anger reached its peak. He grabbed the man by the collar and said through gritted teeth: "Tell me, where is she!"

At this moment, there was a sound of hurried footsteps at the entrance of the secret room. Lin Feng turned around suddenly and saw Tony Stark in a steel armor appearing at the door. His armor was gleaming in the dim light, and his mask was opened, revealing his confident and stern face.

"Lin Feng, calm down." Tony's voice was low and steady. He walked forward and raised his hand to signal Lin Feng to let the man go.

"Tony, he knows where my sister is!" Lin Feng's voice contained a hint of pleading and despair, but his hand still did not loosen.

Tony's eyes locked on the man's face and his tone was stern, "He'll tell us, but not this way. We need him alive."

Lin Feng's fists were clenched, veins were exposed, and the anger in his heart was burning like a flame. He took a deep breath, forced himself to calm down, and finally let go. The man fell heavily to the ground, holding his chest, coughing, and still had that crazy smile on his face.

Tony leaned over and looked at the man coldly, "You'd better cooperate obediently, otherwise, you will find out that we have plenty of ways to make you talk."

The man sneered but said nothing more. Tony motioned Lin Feng to follow him out, and the two walked out of the secret room one after the other.

"Lin Feng, I know you are worried about your sister, but we must act calmly." Tony patted Lin Feng on the shoulder, with a hint of concern in his tone, "We will definitely find her."

Lin Feng was silent for a moment, took a deep breath, and nodded, "I know, I just don't want to lose her again."

Tony's eyes softened a little, and he whispered, "We are all your friends, and we will face these difficulties together."

Lin Feng felt a little warm in his heart. He knew that he was not fighting alone. Every member of the Avengers was his comrade-in-arms. They faced these dangers and challenges together. He looked at Tony with a firm gaze, "Thank you, Tony. I will calm down."

Tony nodded and turned away. His steps were steady and powerful, with invisible power in every step. Lin Feng looked at his back and gradually calmed down. He knew that there would be more battles waiting for them, and he had to stay calm and wise to find his sister's whereabouts.

In the following days, Lin Feng and the Avengers continued to investigate the Hydra conspiracy. Every action was full of danger, but every victory brought them one step closer to the truth. Lin Feng's heart burned with hope, and he firmly believed that he would be able to find his sister and solve the mystery.

Late one night, Lin Feng sat alone on the top floor of Stark Tower, overlooking the city at night. Neon lights flickered, traffic was hustling, and the hustle and bustle of the city gradually blurred in his eyes. His thoughts went back to that night many years ago, when the flames shot up into the sky and the screams of his family members echoed in his ears. Those tragic scenes were deeply engraved in his heart and became his indelible pain.

"What are you thinking about?" A gentle voice sounded behind him.

Lin Feng turned around and saw Natasha standing not far away, looking at him with a smile, with a hint of concern and understanding in her eyes.

"Thinking about the past." Lin Feng said softly, with a hint of sadness in his eyes.

Natasha walked up to him, sat next to him, and patted his shoulder gently. "We all carry our own past, but what's important is how we face the present and the future."
