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

However, when Lin Feng returned to the real world, he found that the Red Skull's conspiracy was not completely over. Hydra's power in the real world still existed, and their remnants were still operating in secret. Lin Feng understood that his battle was not over yet.

After returning to New York, Lin Feng and the Avengers continued to fight side by side, tracking down the remnants of Hydra and exposing their conspiracy. Every battle made Lin Feng more determined in his belief that only by completely eradicating Hydra can he seek justice for his family and those innocent victims.

Lin Feng squatted in the corner of the laboratory, took a deep breath, and his heartbeat gradually calmed down. He looked around, and the air was filled with a pungent chemical smell. The room was filled with various complex instruments and equipment, which seemed extremely mysterious and dangerous. He took a cautious step, trying not to make any noise.

"Natasha, there is a prison area here. I suspect an important person is imprisoned there." Lin Feng whispered to Black Widow through the headset.

"Got it. I'm in the monitoring room and saw your location. Be careful, there are two guards over there." Natasha's voice came from the headset, calm and capable.

Lin Feng held his breath, hid in the shadows, and locked his eyes on the two guards. His heartbeat quickened, and his mind quickly thought of the next action. He quickly took out the knife from his waist and quickly passed behind the two guards. The sound of the blade cutting through the air was barely audible, and then the two guards fell silently.

"Done," Lin Feng whispered, feeling relieved. He walked towards the heavy iron door and pried open the lock with a knife.

Behind the door was a simple prison cell, where an exhausted scientist was tied to a chair. His face was covered with bruises, and his eyes were filled with despair and fear. When he saw Lin Feng, a glimmer of hope flashed in the scientist's eyes.

"Who are you?" the scientist asked in a trembling voice with a thick accent.

"I'm here to save you." Lin Feng replied in fluent foreign language, while untying the scientist's restraints and carefully observing his expression.

"Thank you, thank you!" The scientist thanked repeatedly, his eyes full of gratitude.

"We don't have much time," Lin Feng said nervously, "What experiment is Hydra conducting?"

"They are using extra-dimensional energy to create a weapon that can destroy an entire city." The scientist's voice was low and full of fear. "We must stop them."

Lin Feng nodded, a firm determination rising in his heart. He pulled the scientist and quickly walked towards the exit of the laboratory. "Follow me closely, we must leave here as soon as possible."

They carefully avoided several waves of patrolling guards along the way. Lin Feng's heartbeat quickened, and his sister's face kept appearing in his mind. After the catastrophe many years ago, he lost all his relatives, and only his sister's whereabouts remained a mystery in his heart. He firmly believed that the conspiracy of Hydra was inextricably linked to his sister's disappearance.

"Lin Feng, the passage outside the laboratory has been cleared, come out quickly." Natasha's voice came again, making Lin Feng feel relieved.

They quickly passed through the laboratory and came to the exit. The air outside was much fresher, but the danger was not over. Lin Feng and the scientists hurriedly got into a pre-prepared vehicle. Natasha had been waiting in the driver's seat for a long time.

"Let's go, let's get out of here quickly." Lin Feng ordered. Natasha stepped on the accelerator and the car quickly drove away from Hydra's secret laboratory.

In the car, the scientist was panting, obviously not yet recovered from the thrilling experience. Lin Feng closed his eyes and tried to calm himself down. Every time he fought, he pushed himself to become stronger, but he knew that the real challenge was still ahead.

The car drove into the safe house, and Lin Feng led the scientist into a hidden room where other members of the Avengers had been waiting for a long time.

"This is Dr. Carl. He has information about Hydra's latest plan." Lin Feng introduced.

"Thank you for saving me," Dr. Karl said gratefully, "Hydra is planning to use extra-dimensional energy to destroy the entire city. Their base is located in a hidden valley with a powerful defense system."

"Where is the location of the Valley?" Steve Rogers asked, a determined gleam in his eyes.

"In a remote mountain range. The exact coordinates are on this map." Dr. Carl took out a hand-drawn map with detailed routes and locations of defense facilities marked on it.

Lin Feng looked at the map carefully and quickly formed an action plan in his mind. He knew that this operation was crucial and any mistake could lead to the destruction of the entire city.

"We need to make a detailed plan to destroy their base." Lin Feng said calmly, looking at the members of the Avengers with a firm gaze.

In the next few days, Lin Feng and the Avengers members prepared for this operation nervously. Every detail was repeatedly scrutinized, and every step was carefully calculated. Lin Feng had mixed feelings. He knew that this operation was not only to stop Hydra's conspiracy, but also to find clues about his sister.

On the day of the operation, Lin Feng stood at the entrance of the valley and took a deep breath. The air was filled with tension, and he could feel every nerve tense. He turned around and looked at his teammates, and everyone's expressions were extremely solemn.

"Are you ready?" Steve asked in a low voice, the shield in his hand flashing faintly.

"I'm ready." Lin Feng nodded firmly, with the flame of revenge burning in his eyes.

They entered the valley carefully, avoiding the Hydra patrols. Every step was extremely cautious, and every breath seemed particularly heavy. Lin Feng's heartbeat accelerated, and his sister's face appeared in his mind, that pure and innocent face.

Suddenly, a burst of hurried footsteps broke the silence of the valley. Lin Feng quickly made a gesture, and his teammates immediately hid. He held his breath and stared at the front.

Several Hydra soldiers hurried past and didn't seem to notice their traces. Lin Feng breathed a sigh of relief and signaled everyone to keep going.

They went deeper into the valley and came to a hidden cave. Dr. Carl pointed at the cave and said, "This is the entrance to their base. There is a powerful defense system inside. We must be careful."

Lin Feng nodded and led the way into the cave. The cave was dark and damp, and the air was filled with a rotten smell. His eyes were as sharp as a knife, and his body was as tight as a bowstring, ready to deal with sudden dangers at any time.

After walking for a while, they came to a spacious underground hall. In the center of the hall, a huge machine was running, making a low humming sound. Around the machine were Hydra scientists and soldiers, who were busy operating something.
