Chapter 239: Feeling a little anxious.

This is an abandoned factory, surrounded by heavy guards. Lin Feng's heartbeat accelerated, but he forced himself to stay calm, knowing that the success or failure of this operation was related to the lives of many people.

"Lin Feng, you go to the left, Peter takes charge of the right, and I'll cover you in the middle." Wanda commanded in a low voice, her voice revealing calmness and decisiveness.

Lin Feng nodded and quickly sneaked into the left area. He carefully avoided the patrolling guards and gradually approached the interior of the factory. Suddenly, he found a familiar object in a corner - his younger brother Lin Hao's necklace.

Lin Feng's heart skipped a beat, he picked up the necklace and found some fresh blood on it, which made him feel extremely uneasy and angry, his brother was obviously in danger.

"Peter, Wanda, I found some clues." Lin Feng whispered through the communicator, his voice full of anxiety.

Peter responded quickly: "What clue?"

"This is my brother's necklace. He may be trapped here." Lin Feng held the necklace tightly with a firm look in his eyes.

"We will find him," Wanda soothed, "Now we have to complete our mission and then rescue your brother."

Lin Feng nodded and forced himself to calm down. He continued to move forward, praying for his brother's safety. As they went deeper into the factory, Lin Feng and Peter discovered a hidden underground laboratory. In the laboratory, the remnants of the Shadow King were conducting some dangerous experiments.

"We have to destroy these devices," Peter whispered.

Lin Feng agreed and started to act quickly. They destroyed the core device of the laboratory, causing a series of explosions. The enemy discovered their actions and quickly surrounded them. Lin Feng and Peter fought fiercely with the enemy, and Wanda's magic provided them with powerful support.

During the battle, Lin Feng felt the chaotic energy in his body surging. He tried to control this power and transform it into a powerful attack. Every time the energy was released, the enemy retreated, but he knew that he had to find his brother's whereabouts.

Finally, during the interval of the battle, Lin Feng found a locked hut. He broke in and saw his brother Lin Hao tied to a chair with several scars on his face.

"Haohao!" Lin Feng rushed forward and quickly untied his brother's rope.

Lin Hao opened his eyes and saw his brother, with a flash of joy and pain in his eyes: "Brother, I knew you would come to save me."

Lin Feng hugged his brother tightly, with an indescribable feeling in his heart: "I'm sorry, Haohao, I'm late."

Lin Hao shook his head and said weakly: "It's okay, I'm glad you're here."

Peter and Wanda also rushed over to protect Lin Feng and Lin Hao's evacuation. Outside the factory, the Avengers had already taken control of the situation and the enemies were repelled one after another.

"We did it," Wanda said with a smile, relief in her eyes.

Lin Feng looked at his brother and said to Peter and Wanda gratefully: "Thank you, without your help, I would not be able to rescue Haohao."

Peter patted him on the shoulder: "We are a team, this is what we should do."

Back at the Avengers base, Lin Feng and Lin Hao finally had a moment of peace. Lin Hao was receiving treatment in the medical room, while Lin Feng stayed by his side, his heart full of gratitude and determination.

"Brother, will you always be by my side?" Lin Hao asked weakly.

"Of course." Lin Feng answered firmly, "I will always protect you."

At this moment, Lin Feng felt that the responsibility on his shoulders was even heavier, but he also understood that only by growing and becoming stronger could he truly protect the people he loved. Although the threat of Shadow King was temporarily lifted, the future battle would continue. Lin Feng knew that this was only a stage in his journey in the Marvel world, and he still had many unfinished missions and challenges.

Lin Feng came to the laboratory and saw Bruce busy conducting various experiments. The laboratory was full of various high-tech equipment, and the air was filled with a faint smell of chemicals.

"Bruce, are you free? I want to discuss something with you." Lin Feng said, with a hint of nervousness in his tone.

Bruce raised his head, pushed up his glasses, and smiled: "Of course, Lin Feng, what's the matter?"

Lin Feng approached and organized his words: "I think I need stronger equipment to cope with future battles. Can you help me design some enhanced equipment?"

Bruce thought for a moment and nodded: "Of course. Your current abilities are very powerful, but if you have the right equipment to support you, you will definitely be able to unleash greater potential. Let's test your energy fluctuations first, and then decide on a specific design plan."

Lin Feng agreed and followed Bruce to a huge energy testing device. He stood in the center of the device, and Bruce started the device. As the device was running, Lin Feng felt a weak current passing through his body, and the energy fluctuations were recorded one by one.

"The chaotic energy in your body is very unstable. We need to find a way to balance it." Bruce said as he looked at the data.

"How long will it take?" Lin Feng asked, feeling a little anxious.

Bruce smiled and replied, "Don't worry, we'll get it done as soon as possible. Just a preliminary design first, and then some debugging."

A few days later, Bruce presented a preliminary equipment design. This equipment includes a high-tech armor that can enhance Lin Feng's energy control and a special glove that can release more powerful energy waves.

"Try it on and see how it feels." Bruce handed over the armor and gloves.

Lin Feng took the equipment and put it on carefully. He felt that the armor fit him very comfortably and the gloves were light and flexible. He tried to release an energy wave and found that the control of energy was more precise and powerful.

"It feels great!" Lin Feng said excitedly, with a gleam in his eyes.

Bruce nodded, looking satisfied. "Very good, this is a good start. We will continue to optimize it so that you can be more comfortable in battle."

In the following weeks, Lin Feng and Bruce continued to adjust and test, and finally the equipment reached the ideal state. Lin Feng felt that his strength had been greatly improved, and he was full of confidence and expectation.

One night, Lin Feng was practicing alone in the training room wearing his new equipment. He felt the energy flowing through his body, full of power and control. He knew that this set of equipment would become an important weapon in his battle.

Suddenly, the communicator rang. It was Peter Parker's voice: "Lin Feng, there is an urgent task. Gather in the conference room."

Lin Feng quickly rushed to the conference room and saw that the Avengers had gathered. Tony showed the latest intelligence: "The remnants of the Shadow King are active in an abandoned laboratory. We must act quickly to destroy their base."
