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

A trace of calmness and determination flashed in Lin Feng's eyes, "Okay, we'll set off right away."

Lin Feng and Black Panther shuttled between the tall buildings in the city, and the night obscured their figures. Lin Feng felt the new power flowing in his body, but along with this power, there was also a vague sense of discomfort. Every time he moved violently, he would feel a sharp pain in his chest, as if countless needles were piercing his internal organs.

"Lin Feng, you look a little strange." Black Panther stopped on a roof, turned to look at Lin Feng, a hint of worry flashed in his eyes.

Lin Feng forced a smile and said, "It's okay. Maybe I'm still adapting to this new power."

Black Panther frowned, "You must take care of your body. The side effects of this power may be more serious than you think."

Lin Feng nodded, but his heart was still full of determination. He knew that this power was chosen by him to protect the city, and he would not regret it no matter what the price.

They continued to move forward, their target was an abandoned warehouse. Intelligence showed that criminal organizations were gathering here, preparing for a large-scale sabotage operation. Lin Feng and Black Panther needed to act quickly to stop their plan.

Arriving outside the warehouse, Lin Feng felt the discomfort in his body getting stronger. He took a deep breath and tried to calm his anxiety. He knew that now was not the time to retreat, he had to persevere.

"Let's split up. I'll go in through the front door and you sneak in through the back door. Make sure they don't have any chance to escape." Black Panther whispered, his eyes calm and determined.

Lin Feng nodded and quickly moved towards the back door. Although his physical discomfort made him move a little slowly, he still remained highly alert and ready to respond to any emergency at any time.

Entering the warehouse, Lin Feng found that it was heavily guarded, with fully armed guards everywhere. He hid in the shadows, observing the movements around him, silently calculating the best course of action.

Just as he was about to act, he suddenly felt a sharp pain in his chest, causing him to frown. He tried to suppress the pain, took a few deep breaths, and then quickly attacked and killed several guards.

After dealing with the guards on the periphery, Lin Feng moved cautiously into the depths of the warehouse. He knew that there must be stronger enemies waiting for him in the core area.

Finally, he arrived at a spacious hall and found several leaders of criminal organizations discussing something. He quietly approached and heard their conversation.

"The operation must be carried out quickly. We can't give them any time to react." said one of the leaders, his tone revealing tension and anxiety.

Lin Feng knew that he had to act immediately and not give them any chance to implement their plan. He took a deep breath, endured the pain in his body, and rushed out.

The enemies in the hall were startled by the sudden attack, but they quickly reacted and picked up their weapons to engage in a fierce battle with Lin Feng. With his newfound strength, Lin Feng quickly knocked down several enemies, but the discomfort in his body became more and more intense, and every attack made him feel a sharp pain.

Just when he was about to be suppressed by the enemy's counterattack, Black Panther suddenly rushed in from the other side and fought side by side with Lin Feng. The two of them cooperated tacitly and quickly dealt with the remaining enemies.

"Are you okay?" Black Panther asked with concern, a hint of worry in his eyes.

Lin Feng nodded and tried to smile, "I'm fine, mission accomplished."

Black Panther frowned, but said nothing more. He knew Lin Feng's stubbornness, so he could only silently support his decision.

The two quickly cleaned up the scene, making sure nothing was left untouched, and then left the warehouse and returned to the city's night.

On the way back, Lin Feng's physical condition became worse and worse. Every step he took caused him to feel a sharp pain in his chest, which made it almost impossible for him to breathe. But he gritted his teeth and insisted on not falling down. He knew that now was not the time to rest, and there were more tasks waiting for him to complete.

A few days later, Lin Feng and Black Panther received a new mission. This time, they needed to go to an abandoned factory, which was said to be an important base of a criminal organization.

"Lin Feng, this mission may be very dangerous. Are you sure you want to continue?" Black Panther asked, with a hint of uneasiness in his tone.

Lin Feng nodded, his eyes gleaming with determination, "I have decided, no matter what the cost, I will continue to fight."

Black Panther sighed, but did not dissuade him. He knew Lin Feng's determination and could only silently support his choice.

They set off quickly and headed for the target location. On the way, Lin Feng felt the pain in his body becoming more and more severe, but he still endured it and insisted on completing the task.

After arriving at the factory, they found that the defense here was tighter than expected. Lin Feng and Black Panther acted separately, quickly cleared the guards outside, and then headed into the factory.

Entering the factory, Lin Feng felt a strong sense of uneasiness. He knew that this mission would be extremely difficult, but he had no way out. Every step seemed particularly heavy, and every breath brought a stinging pain, but he still walked forward firmly.

Deep in the factory, they found the leader of the criminal organization and a batch of important intelligence. Lin Feng and Black Panther quickly attacked and started a fierce battle with the enemy.

Each of Lin Feng's attacks was powerful, but each attack also caused his body to suffer great pain. His movements gradually became slower and his vision began to blur, but he still did not give up and tried his best to fight the enemy.

"Lin Feng, hold on!" Black Panther shouted loudly from the side, his voice full of urgency.

Lin Feng gritted his teeth and tried to concentrate. He knew that he could not fall down. No matter how painful it was, he had to complete the mission. Every attack he made was with determination and strength. In the end, they successfully defeated the enemy and took back important intelligence.

After completing the task, Lin Feng's body finally couldn't hold on anymore, his legs softened, and he fell to the ground. Black Panther quickly stepped forward and supported him, "Lin Feng, how are you?"

Lin Feng forced a smile and said weakly, "I'm fine, just a little tired."

Black Panther frowned, "We have to find a place to rest. You need to recuperate."

Lin Feng nodded. He knew that his physical condition had indeed reached its limit and he needed time to recover.

They left the factory and found a safe place to rest temporarily. Black Panther took good care of Lin Feng, making sure he got enough rest and treatment.

During the rest, Lin Feng's heart was filled with mixed emotions. He knew that his body was no longer as strong as before, but he was still determined to continue fighting. He knew that every mission might be the last one, but he was willing to
