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

Doctor Mutation was silent for a moment, as if he was weighing the pros and cons. Finally, he sighed, turned around and made way. "Come in, Lin Feng, let me see what problem you are facing."

Lin Feng followed Dr. Mutation into the laboratory, which was surrounded by various high-tech equipment and experimental instruments, and looked extremely complicated and mysterious.

"Tell me the details," said Dr. Mutation, sitting in a chair, staring at Lin Feng.

Lin Feng described in detail the recent enemy movements and the appearance of Venom. Dr. Mutation listened very carefully and nodded from time to time to show his understanding.

"The appearance of Venom is indeed unusual," Dr. Mutant mused, "It means that the enemy may have mastered a new power, or they have found some way to enhance their own abilities."

"Can you help us find out the source of this power?" Lin Feng asked, with a hint of urgency and hope in his voice.

"Yes, but this requires time and resources," said Dr. Mutation. "You must provide me with sufficient experimental data and samples."

Lin Feng nodded, knowing that this would be a difficult task. "We will do our best to provide what you need, but we need your wisdom and technology."

Dr. Mutation smiled slightly, revealing a mysterious expression. "Well, Lin Feng, it seems that we have to cooperate again. I hope this cooperation will have a good result."

In the next few days, Lin Feng worked closely with Dr. Mutation to collect and analyze various data. They studied the samples of venom, trying to find the key components and energy sources. Dr. Mutation's laboratory was full of various complex formulas and data, and Lin Feng was constantly learning and understanding this knowledge.

"These data indicate that the enemy may have utilized an unknown energy source," Dr. Mutation said, his eyes flashing with wisdom, "This energy source can greatly enhance a person's strength and abilities."

"Then can we find the source of this energy?" Lin Feng asked, his heart full of anticipation.

"Perhaps, but we need more clues," said Dr. Mutation, "You need to continue investigating and find more evidence."

Lin Feng nodded, he knew that this meant they had to continue taking risks and face more dangers. But he was not afraid, he had firm faith and determination.

"Thank you, Doctor," Lin Feng said, his voice full of gratitude, "We will continue to work hard to find more clues."

Doctor Mutation smiled and nodded, "I hope you can succeed, Lin Feng. The world needs heroes like you."

Lin Feng left the laboratory with new hope and strength in his heart. He knew that their mission was not over yet and there were more challenges waiting for them in the future. But he believed that as long as they were united, they would be able to overcome all difficulties.

When Lin Feng returned to the Avengers headquarters, his teammates were already waiting for his news. They gathered together and listened to Lin Feng talk about the results of his cooperation with the mutant doctor.

"The doctor believes that the enemy has used an unknown energy source," Lin Feng said, "We need to find the source of this energy source before we can completely solve the problem."

"It looks like we still have a lot of work to do," Tony mused, "but this is at least a good start."

"We need more clues," Natasha said, her eyes full of determination, "We must continue investigating."

Lin Feng nodded, his heart full of confidence and determination. He knew that as long as they did not give up, one day they would find the truth, defeat the enemy, and protect the peace and justice of the world.

Lin Feng stood in front of the window of the Avengers headquarters. As the night deepened, the lights of the city blurred in his eyes. His thoughts did not settle down, but became more chaotic. He knew that the unknown energy source used by the enemy was a huge threat, and they had to find and destroy it as soon as possible.

"Lin Feng, what are you thinking about?" Natasha walked to him and asked softly.

"I'm thinking about the battle ahead," Lin Feng replied, his eyes still not leaving the window, "I'm worried that the enemy we face will be much stronger than we expected."

Natasha patted his shoulder gently and said, "We will face it together. No matter how powerful the enemy is, we will not back down."

Lin Feng nodded and turned to look at Natasha, "You are right, we can't retreat."

At this moment, Lin Feng suddenly felt an inexplicable pain coming from his body, and his face turned pale instantly. Natasha immediately noticed his abnormality and asked anxiously, "Lin Feng, what's wrong with you?"

"I... I don't know either," Lin Feng clenched his teeth, trying to hold back the pain, but the pain became more and more intense. His body began to tremble uncontrollably, and cold sweat oozed from his forehead.

"We need a doctor!" Natasha shouted. She supported Lin Feng and tried to get him to sit down.

When Lin Feng opened his eyes again, he found himself lying in the infirmary of the Avengers headquarters, surrounded by various medical equipment. He felt that the pain in his body had eased, but there was still a strange feeling spreading in his body. Bruce Banner and Natasha stood beside him, their faces full of concern.

"How are you feeling?" Bruce asked, worry thick in his voice.

"I...seem to be fine." Lin Feng tried to force out a smile, but he was still a little uneasy in his heart. "What happened just now?"

"You suddenly felt severe pain and then passed out," Natasha explained, with a hint of doubt in her eyes. "The doctor examined your body and found no obvious abnormalities."

"But we can't be careless," Bruce added, "Your body may be undergoing some changes, and these changes may be related to our previous mission."

Lin Feng nodded, feeling that Bruce's words made sense. He recalled the previous battle with Venom, and that unknown energy source might have affected his body unconsciously.

"I need more time to observe the changes in my body," Lin Feng said, his voice full of determination, "but I can't stop because we still have a mission to complete."

"You need to rest," Natasha said seriously, "Your health is more important than the mission."

Lin Feng was about to retort when he suddenly heard a familiar laugh. He turned around and saw Black Panther walking into the infirmary with a playful smile on his face.

"Lin Feng, do you always disobey the doctor?" Black Panther said with a smile, his eyes full of friendly teasing.

"Black Panther, long time no see," Lin Feng smiled, trying to ease the tense atmosphere, "You came here today
