Chapter 206 A dark shadow rushed out from the depths of the laboratory

Lin Feng nodded, feeling a little warm in his heart. He knew that Natasha was right, the past could not be changed, and only the future was truly in his control.

"Thank you, Natasha." Lin Feng said with a smile, his eyes regaining some determination, "I will continue to fight until I find my sister."

Natasha smiled softly, "We will all support you. No matter what happens, we are your comrades."

Lin Feng took a deep breath and felt the power in his heart awaken again. He stood up and looked into the distance with a determined gaze, his heart burning with an inextinguishable fighting spirit. He knew that the road ahead was still full of thorns and challenges, but he was ready to face everything.

The next morning, the Avengers assembled again. Lin Feng and his teammates worked out a detailed action plan to attack another secret base of Hydra. This time, intelligence showed that this base might contain important clues about his sister.

After the operation began, Lin Feng and his teammates quickly entered the target area. This base was hidden in a dense forest and had tight defenses. They carefully passed through the woods and avoided the patrolling guards.

"According to the intelligence, there should be an underground facility here and we need to find the entrance." Steve whispered, scanning the surroundings with sharp eyes.

Lin Feng nodded and observed the terrain carefully. Suddenly, he found something unusual on a piece of ground that was not very conspicuous. He walked over and tapped the ground lightly, and a hollow sound came out.

"There is a secret door here." Lin Feng whispered, and then used a knife to pry open the secret door on the ground. Below was a staircase leading underground.

"Very good, everyone be careful." Steve signaled everyone to follow. Lin Feng walked in front and took the lead into the underground facility.

The lights in the underground facility were dim, and the air was filled with a damp and musty smell. They walked along the long and narrow corridor, taking every step with extreme caution. Lin Feng's heartbeat quickened, and he felt that he was getting closer and closer to the truth.

At the end of the corridor was a heavy iron door. Lin Feng pushed it open carefully and found a spacious laboratory inside. Various instruments and equipment were running in the laboratory, and several scientists were working busily.

"Go!" Steve gave the order, and the Avengers quickly launched their attack. Lin Feng rushed forward and subdued several scientists in a lightning speed.

"Tell me where my sister is!" Lin Feng grabbed a scientist by the collar, with flames of anger flashing in his eyes.

The scientist looked at him in horror and stammered, "I don't know... I don't know about your sister..."

Lin Feng's anger grew more intense, and he increased the strength of his hands, "Don't lie!"

Just then, a voice came from the corner of the laboratory, "Let him go, Lin Feng."

Lin Feng turned around suddenly and saw Tony Stark walking out from the shadows with a gloomy face.

"Tony, this person knows the whereabouts of my sister!" Lin Feng said angrily, his hands

Tony Stark's face was solemn, and his tone was calm and firm, "Lin Feng, calm down. We need to get valuable information from him, not let him keep silent out of fear."

Lin Feng took a deep breath, and the anger in his heart gradually subsided. He knew Tony was right, and he couldn't let his emotions control his reason now. He let go of his hand, and the scientist collapsed to the ground, with a trace of fear on his face.

Tony leaned over and spoke to the scientist in a calm and intimidating tone, "Tell us what you know, or you will suffer the consequences."

The scientist nodded tremblingly. "I... I only know that they are conducting an experiment to use energy from another dimension to transform humans. That girl... she is one of the subjects of the experiment."

Lin Feng's heart suddenly trembled, and his sister's face appeared in his mind. He clenched his fists, his eyes sharp as a knife, "Where is she now?"

"She...she was transferred to a more secret base where the facilities are more advanced and the defenses are more stringent." The scientist's voice trembled and was full of fear.

Lin Feng felt a glimmer of hope. Although his sister's whereabouts were still unknown, at least there was a new clue. He stood up with a determined look, "Tony, we must find that base and rescue my sister."

Tony nodded, a hint of approval in his eyes, "We will, Lin Feng. This is just the beginning."

The members of the Avengers continued to investigate the conspiracy of Hydra and finally found the location of the more secret base. It was an abandoned factory surrounded by dense forests, which looked dilapidated, but inside it was the latest experimental facility of Hydra.

Lin Feng and his teammates carefully sneaked into the factory, avoiding patrolling guards and high-tech monitoring equipment. They walked all the way and came to a heavy iron door.

"This is the entrance," Tony whispered, "Everyone be careful, there may be more powerful enemies inside."

Lin Feng nodded, his heartbeat quickened, and he felt a mixture of nervousness and anticipation. He knew that this operation was not only to stop the Hydra conspiracy, but also to find his long-lost sister.

The heavy and solemn iron door slowly opened to both sides with a dull sound. It seemed like a mysterious door leading to an unknown world. The scene before one's eyes was jaw-dropping - it was a vast, intricate underground laboratory that was like a maze!

As far as the eye can see, rows of towering metal racks are neatly arranged, filled with all kinds of instruments and equipment with strange shapes and functions. These high-tech creations flash with cold light and exude an awe-inspiring atmosphere. They operate silently, seemingly carrying out some important task, but their true purpose is shrouded in a thick fog.

The whole laboratory was filled with a bone-chilling cold that made people shiver. This coldness was not just from the low temperature, but more like a fear and uneasiness from deep in the heart. In this silent space, time seemed to freeze, and everything seemed so solemn and depressing.

Suddenly! A black shadow rushed out from the depths of the laboratory like lightning! Lin Feng was quick-witted and reacted quickly, narrowly avoiding the attack of the black shadow! However, the scene that happened next made his heart sink suddenly!

It turned out to be an evolved version of venom! Its body showed a strange black tone, and its muscles were abnormally developed, as if it contained endless terrifying power! Its pair of eyes flashing red were filled with violence and desire for killing, which was chilling!

"It's the evolved version of Venom!" Tony shouted, quickly put on his armor and prepared to fight.

Lin Feng clenched the weapon in his hand, his eyes were cold, "Be careful, this guy's venom is stronger than before."

Venom roared and quickly pounced on Lin Feng. Lin Feng dodged and swung the blade towards Venom's body. The blade passed through Venom's body, but it was like cutting on hard metal, making a harsh friction sound.
