Lynn's team worked overtime overnight to analyze all the residual materials extracted from the arson scene. After detailed chemical and energy analysis, the technical department finally confirmed a key clue - the energy traces left by the fire had a unique mutant genetic signature.

The technician presented the results to Lynn: "Inspector, we've discovered a high concentration of residual thermal energy particles. The way they fluctuate matches the abilities of a certain mutant. His code name is 'Heart of Fire'."

Lin En frowned slightly. "'Heart of Fire'? Sounds like a professional code name for an operation."

The technician continued, "According to the mutant database, 'Flameheart' is an extremist mercenary. His ability is to control and enhance flames, but he is not an independent actor. His whereabouts are usually accompanied by the activities of extremist organizations, especially in areas sensitive to mutant issues."

"Does he have a particular background?" Lynn asked.

The technician nodded and pulled up a file. "His true identity remains unknown, but it's rumored he's a modified mutant who once worked for an underground organization. His appearances over the past few years have typically been accompanied by high-precision, devastating attacks."

Lin En looked down at the information and said coldly, "So we're not dealing with an ordinary arsonist, but a well-trained killer. Finding him might reveal the motive behind this entire case."

Lynn gathered the team and set up an infographic about Heart of Fire in the war room. The screen showed the scope of his activities and the cases he had been involved in over the past few years.

"'Flameheart' is no ordinary mercenary," Lynn said, pointing to the map on the screen. "He primarily carries out destructive missions, never leaving anyone alive. However, his actions always have clear targets—they either strike at enemies of the mutant community or facilities closely related to mutant issues."

Carter flipped through the files and asked, "Inspector, if he was targeting mutant enemies, why would he set fire in Manhattan? This fire seems completely untargeted."

"That's because we don't have all the information yet." Lynn thought for a moment, "Perhaps this fire itself is not aimed at a specific target, but a test, or - a warning."

"Warn who?" Carter asked.

"It could be us," Lynn whispered, "or it could be targeting those forces that are secretly opposing mutants. Who is the employer behind 'Heart of Fire'? That's the key."

Meanwhile, Kate didn't stop her investigation. Through her connections, she contacted an anonymous source who claimed to be a member of the mutant underground network. He was willing to provide some clues about "Heart of Fire" on the condition that he remain anonymous.

Kate met the informant in a secluded cafe. The informant, wearing a hat and with his head lowered, said, "'Heart of Fire' is not a person. He is a symbol - more accurately, a code name. There may be several people behind it."

"What do you mean?" Kate asked nervously.

"The codename 'Flameheart' is well-known in the mutant community. He is the ace assassin of the extremist organization 'Dawn'. 'Dawn' is an organization that aims to overthrow the existing order. They attempt to use violence to force the government to recognize the special status of mutants."

"'Dawn'? What do they have to do with this fire?" Kate asked.

"This fire is a signal that they may be preparing for a larger operation. The appearance of 'Heart of Fire' is only the first step in their plan."

Kate was shocked after hearing these words. She realized that this was not just an isolated incident, but a far-reaching conspiracy.

Kate did not hide the information she obtained. She contacted Lynn directly and told him about the "Dawn" organization over the phone.

"Kate, this is dangerous." Lynn's voice was filled with dissatisfaction. "You shouldn't have contact with these people, especially without any protection."

"I don't have time to think about this, Lynn," Kate said firmly. "If Dawn is really planning a larger operation, the public has a right to know the truth."

Lin En was silent for a moment, then said, "Okay, bring me all your clues. We need to fully understand the Dawn's network of operations, especially their relationship with Flame Heart."

Soon after, Kate brought her notes and recordings to the FBI branch and shared her findings with Lynn and his team. Through cross-references, Lynn finally found a breakthrough clue - a secret base of the "Dawn" organization was hidden in an abandoned shipyard in Manhattan.

Lin En quickly assembled a task force to raid the abandoned shipyard. They conducted a precise reconnaissance before the operation and discovered multiple heat sources within the factory, suggesting that members of the "Dawn" group were active.

As night falls, the action begins.

"Everyone remain silent," Lin En whispered through the headset, "We'll act again after confirming the target."

The task force was divided into two groups, one responsible for external surveillance, and the other, led by Lin En himself, to enter the factory. A burning smell hung in the air, and the lights inside the factory flickered, creating a strong sense of unease.

"Inspector, there is a set of devices here!" a team member whispered, pointing to a metal box placed in a corner.

Lin En walked closer and found a set of high-performance incendiary devices inside the box, seemingly designed to create large-scale fires. He frowned, "They're preparing for their next attack."

At this moment, an emergency alarm came from Lin En's headset: "Inspector! We have found a moving heat source. Its body temperature is much higher than that of an ordinary person. It is suspected to be the 'Heart of Fire'!"

Lin En's eyes turned cold: "Lock on his location! I'll handle it."

Lin En led the team to track the target and finally found him in a warehouse deep inside the factory. The figure stood in front of a pile of fuel barrels, surrounded by blazing flames, as if the flames themselves were part of him.

"'Heart of Fire'!" Lynn pointed the gun at him, "Put down the device, or I'll shoot."

The other party turned around, revealing a face distorted as if branded by flames, his eyes filled with anger and contempt: "You ordinary people always think you can control everything, but fire cannot be tamed!"

"This game is over," Lin En said coldly. "We know your plan and the existence of Dawn. Surrender, or face the consequences."

"You think that capturing me will end everything?" Flame Heart sneered, "This is just the beginning."

Before he finished speaking, he suddenly raised his hands and flames gushed out from his palms. Lin En immediately rolled over to avoid it.

Lin En dodged the blazing flames. The temperature inside the warehouse rose rapidly, and the air was filled with a thick smell of sulfur. Flame Heart stood beside the fuel barrels, his hands radiating a fiery orange-red glow, as if flames were pouring from his veins. "You can't catch me, Inspector!" Flame Heart sneered and waved his hand. A wall of fire swept across, instantly cornering Lin En.

Lin En leaned back against the cover, quickly analyzing the situation. He knew that a direct confrontation was unwise. Flameheart thrived in such an environment, and his abilities had clearly been enhanced, far surpassing those of ordinary mutants.

"Why are you doing this?" Lynn asked loudly, trying to buy time. "What does it really prove if you hurt innocent people?"

"Innocent?" Flameheart's laughter was tinged with anger. "Those so-called innocents climbed up on our corpses! They enjoy privileges, while we mutants are deprived of everything!"

Lynn heard the anger and pain in his words and tried to guide him: "If you really want to change this, using violence will only make the situation worse. You should know that such actions will only make more people hate mutants."

Flame Heart's expression froze for a moment, but then he became even more excited: "You simply don't understand! Only fear can make those high and mighty bow their heads!"

Taking advantage of Flame Heart's emotional fluctuations, Lin En leaped from behind cover, aiming his weapon at the fire extinguisher above the warehouse. He pulled the trigger, and the bullet accurately hit the valve. White fire-extinguishing foam gushed down from the ceiling, quickly covering the entire warehouse.

The heart of the flame was suppressed by the foam, and the flames gradually weakened. He roared and waved his hands frantically to try to reignite the fire, but the chemical reaction of the fire-extinguishing foam greatly weakened his ability.

Lin En seized the opportunity, quickly approached Flame Heart, and aimed the stun gun at his legs. With a "sizzle", Flame Heart's body shook, and he fell to the ground, the flames around him completely extinguished.

"It's over." Lin En said coldly, buckling the special restraint device on Flame Heart's wrist, "You have no way to escape."

Flame Heart panted, his eyes still filled with unyielding determination. "You think that by capturing me, you can stop the rise of the Dawn? We are the judges of this corrupt society. You cannot stop us."

Lin En was silent for a moment, then whispered, "Judge? You're just another tool to manipulate violence."

After Flame Heart was controlled, Lynn's team began to clean up the warehouse and look for more clues. Carter came over with a yellowed map in his hand.

"Inspector, there's something wrong here." Carter pointed to the mark on the map. "This isn't just Flame Heart's hideout; it's also the Dawn organization's center of operations in Manhattan."

Lynn took the map and looked at it carefully. He found that it marked the locations of many Manhattan landmarks, with numbers and dates written next to each location.

"This is the attack plan," Lynn said in a grim tone. "They're not just trying to create chaos. These numbers could be the time—the countdown to action."

Carter nodded. "If these plans were carried out, all of Manhattan would be plunged into panic."

"Collect all documents and send them to the technical team immediately," Lin En ordered. "At the same time, strengthen security measures at these target locations."

Meanwhile, Kate learns of Lynn's successful capture of Flame Heart and rushes to the FBI office to get more information, but Lynn remains cautious.

"Lynn, you have to tell me what happened," Kate insisted. "The public needs to know the truth."

Lynn shook her head. "Kate, now is not the time. We have just obtained some key intelligence. If we make it public rashly, it will only cause panic."

"But you know, there are deeper issues behind these attacks," Kate looked him straight in the eye. "People need to understand, not just for their own safety, but also to change the prejudice against mutants."

Lin En sighed and finally compromised: "Okay, but you can only report on what has already happened and not on future action plans."

Kate nodded and smiled, "Thank you, Lynn."

Just as Kate began writing the report, Lynn's team discovered even more shocking facts while analyzing the plans of the Dawn organization. Not only did they plan to attack Manhattan, they also tried to paralyze the city's energy system through cyber attacks, causing total chaos.

Lynn realized that time was running out, so he assembled his team, quickly developed a countermeasure plan, and contacted Homeland Security for reinforcements.

"We must completely destroy this organization before they make their next move," Lynn said firmly.

In a conversation between Lynn and Kate before the operation, his tone was particularly heavy: "Kate, this time may be more dangerous than any other time. If Dawn succeeds, their extreme methods will push the relationship between mutants and ordinary people into an irreparable abyss."

Kate looked at him and whispered, "I believe you can stop them. No matter what, I will report this and let people know how much you have sacrificed to protect this city."

Lynn nodded. "This is not only for protection, but also for everyone, mutant or not, to live equally. This is our responsibility."

Kate sat in a dimly lit cafe, opposite a man in a hoodie, his face almost hidden in shadow. An untouched cup of coffee sat on the table, and his fingers tapped the surface nervously.

"Kate Bennett, right?" the man asked in a low voice.

"It's me." Kate nodded, trying to make her tone more calm. "I heard that you have clues about the 'Heart of Fire'. I'm willing to listen."

The man whispered, "No one knows the true name of 'Flame Heart', but I know he was hired by a company called Cohen Industries. This company appears to be a legitimate enterprise, but in fact it has close ties with the mutant underground network."

Kate quickly pulled out her notebook. "Cohen Industries? What did they hire Flameheart for?"

"Sabotage, assassination, and even planning attacks against specific targets," the man continued, his eyes etched with caution. "It's said they specialize in recruiting mutants with offensive abilities to complete their dirty work. And Flameheart is one of their most dangerous employees."

Kate frowned. "Why are you telling me this? It sounds dangerous."

The man sighed, a hint of anger in his voice. "Because I used to be a member of Korn Industries. After leaving them, I realized that what they did with mutants' abilities wouldn't bring about any change at all, but would only make the situation worse." (End of this chapter)
