American comics: I am full of martial virtues and I love to be kind to others.

Kate nodded, took a deep breath, and slowly adjusted her posture, trying to steady her arms. The staff member pointed out some small details for her: "You need to adjust your wrist slightly, keep the muzzle pointed at the target, and relax your shoulders. Yes, that's it."

Gradually, Kate's nervousness eased a little, and she began to hold the gun more steadily and aim at the target. Lynn stood by, watching her with a smile: "Good, Kate, stay calm and take your time."

Then, it was Gwen's turn to train. Gwen's reaction was even more direct, her eyes filled with excitement, as if she had a strong curiosity about how to operate a gun. The moment she picked up the gun, her eyes gleamed with excitement, and a hint of mischief lingered at the corner of her mouth: "Brother, watch me!"

Lynn smiled and shook her head: "Gwen, don't worry, remember safety first, control the gun."

Gwen nodded, adjusted her stance according to the staff's instructions, and then took aim at the target. Seconds later, she fired. The sound of the first shot echoed throughout the range, and Gwen's gun sent a powerful vibration, shaking her arm slightly. Although she didn't hit the target exactly, she wasn't discouraged. Instead, she said excitedly, "This feels so exciting! Even though I didn't hit the bull's eye, I can already feel its power."

Lynn came over and patted Gwen's shoulder gently. "Not bad, Gwen, your reaction is very quick. Just practice more and keep your gun steady. You will be able to shoot more accurately in the next few times."

Kate also walked over to Gwen and said with a smile, "I never thought I'd see you so happy. Bro, you're such a good coach."

Lynn felt a warm surge of emotion when he heard Kate's words. He knew that this kind of time was a rare moment of relaxation and joy for Gwen and Kate. Although this training seemed simple, it could help them better protect themselves in life and increase their self-confidence.

Over the next few days, the three took turns practicing shooting. Staff members offered continuous guidance, helping Kate and Gwen adjust their posture and improve their shooting technique. Lynn also observed carefully, offering occasional advice. As the training progressed, Kate's nervousness gradually eased, and she began to hold the gun more steadily and accurately hit the target. Gwen, on the other hand, enjoyed the activity even more, experimenting with her shooting angles, striving to hit the bull's eye every time.

At the end of the training, Lynn looked at Kate and Gwen with satisfaction. "Well done, you've mastered the basic shooting techniques. Although it's only the beginning, you've learned how to stay calm and focused, which is very important for you."

Kate smiled and nodded. "Thank you, Lynn. Today's training was really interesting. Although I'm still a little afraid of guns, I know they can protect me. At least now I'm not so scared anymore."

Gwen said happily, "I never thought shooting could be so fun. It feels like playing a game, but I've definitely learned a lot."

Lynn looked at them, and the smiles on their faces filled him with a deep sense of satisfaction. He knew that, even though it was just a simple shooting drill, it had taught them how to handle unexpected situations and remain calm in the face of danger. For Kate and Gwen, it was a new skill, and for Lynn, it was also a transfer of responsibility—not just for work, but for the people he cared about.

"Keep up this attitude and remember, protecting yourself is always the most important thing." Lynn said to them gently.

As the days of leisure slipped by, the tranquility and beauty of the resort gradually faded into memory. The time Lynn, Kate, and Gwen spent together, though brief, was filled with relaxation and joy. Each day, the three of them savored the rare peace and quiet, chatting and letting go of the heavy responsibilities and pressures of their daily lives. Gwen, in particular, seemed more relaxed and happier than usual. Lynn could sense a change in her sister: less nervous and anxious, more confident and energetic.

However, all relaxation is short-lived, and the time to return home finally arrives. In the morning, sunlight streams through the curtains into the cabin, its warm light inviting. But Lynn knows they must leave. Today, Kate and Gwen both begin packing their belongings, preparing to leave the resort. Gwen's face bears a hint of reluctance as she gently packs her small belongings, her gaze occasionally drifting out the window to gaze at the lake she's always loved.

Lynn stood by the window, gazing at the scenery outside, feeling a mixture of emotions. Although a few days of vacation offered a break from his busy schedule, his deep sense of responsibility and anxiety about the future remained. However, spending time with Kate and Gwen brought him a long-lost warmth and comfort. Seeing Gwen's smile, listening to her and Kate's playful banter, Lynn knew that while life's responsibilities and challenges were always present, these moments spent with his family truly allowed him to find a moment of peace amidst the pressure.

Gwen walked over, lowered her head and sighed softly: "Brother, I really don't want to go back. It's so comfortable here. I can relax. It's really been a long time since I felt this way."

Lynn turned around and looked at her sister with a smile: "I know, Gwen. I don't want to go back either, but you see, I still have work to do and things at home to deal with. Next time, we can come here again, or go somewhere else."

Gwen shook her head, a trace of reluctance on her face: "I really wish time could stop, so that I don't have to rush back to face so many things. But, the next time we come, we will definitely have to wait a long time."

Lin En patted her shoulder gently: "We can agree that we will come again next time. There will always be a chance, don't worry."

Kate came out of the room, packing her backpack. Seeing the two standing together, she smiled and said, "It's time. Is everyone packed? If we delay any longer, we might miss our flight."

Gwen nodded and looked at Kate with a smile: "Sister Kate, I have a request."

"What request?" Kate asked with a smile.

Gwen extended her hand and made an invitation: "Next time, let's come here together, brother and Kate, the three of us together, how about it?"

Kate smiled even brighter: "That's a good idea, I'll definitely do it next time."

Lin En smiled back. "I know you like it here, Gwen. Let's come back next time we have the chance," he said, walking over to his luggage and starting to pack his things. Although Gwen felt a little reluctant to leave, she knew that life had to go on. She turned back and looked at the lake again, a hint of nostalgia in her eyes.

"Okay, brother." Gwen sighed, "Next time we come, we must have more fun."

"Yes," Kate said with a smile, "You have learned how to enjoy life. From now on, no matter where we are, we will go together to play."

The three of them packed the last of their luggage and drove to the resort's gate. Kate sat in the passenger seat, while Gwen and Lynn sat in the back seat. The scenery outside the car window flew by quickly. Lynn felt that the sky was particularly bright today, and the sun shone through the clouds on both sides of the road, giving people a warm feeling. Although the vacation was over, the mood on the way home was not so heavy, but rather a sense of relief. Suddenly, the atmosphere in the car became slightly relaxed. Gwen suddenly stuck her head out from the back seat with a mischievous smile on her face. She looked at Kate and deliberately prolonged her tone: "Sister-in-law——"

Kate was stunned for a moment, then her cheeks turned red and she stood there in a daze. Lynn couldn't help but laugh: "Gwen, don't be naughty, Kate is not used to this name."

Gwen looked at Kate with a playful smile and continued, "Sister-in-law, don't be embarrassed. I just want you to get used to it. After all, you and brother have been together for so long, you have to have a name for him, right?"

Kate blushed like a ripe tomato when she heard the word "sister-in-law." Her mouth parted, unsure how to respond. Lynn couldn't help but smile, and seeing Kate like this, a warm feeling welled up in her heart.

"Gwen, don't tease me like this." Kate said softly, her eyes flickering with shyness, "I'm not used to it yet."

Gwen shook her head in a serious tone, "Sister-in-law, don't be shy. You should have called me that long ago. Otherwise, wouldn't it be too informal for me to be your boyfriend all the time?"

Lin En couldn't help laughing and patted Gwen's head gently: "Gwen, stop thinking about these little things. Don't worry about what's going on between Kate and me."

Kate lowered her head a little embarrassedly: "You two are amazing, Gwen always manages to make the atmosphere so relaxed."

Gwen smiled smugly, seeming to enjoy seeing Kate so shy. "You adults are always embarrassed. Next time you see me, you have to call me sister-in-law."

Kate shook her head helplessly: "Well, it seems I have to get used to this."

Lin En turned around and saw the two people talking and laughing. He felt a warm feeling in his heart, and his originally heavy mood seemed to be diluted by this lightness and joy. Although the future was still full of challenges and unknowns, at this moment, he truly felt that he was not alone.

The car quickly drove to the airport, and the three of them got out and prepared to check in. Gwen and Kate said goodbye to each other, and Kate seemed a little reluctant: "Look, Gwen, you're used to teasing me so quickly. You have to give me some space when you go back."

Gwen laughed even louder: "Don't worry, sister-in-law, I won't always be so naughty. Next time we meet, I will make sure you get used to my humor."

Lin En looked at the two people playing and felt warm in his heart.

The next morning, Lynn returned to Manhattan and resumed his busy work schedule. While his few days at the resort had provided a brief respite, the backlog of work remained immense. He had just arrived at the FBI office from the airport and was about to sit down and begin sorting through some documents when Mark walked in, holding a case report.

"Lynn," Mark said in a serious tone, "I just received the latest intelligence report that there have been recent murders targeting gamblers in Las Vegas. The killer's whereabouts are extremely secretive, and the police are already somewhat overwhelmed."

Lynn raised his head and looked at Mark, his eyes darkening. "Another homicide? Secret whereabouts? This situation sounds like organized crime. What kind of case is it?"

Mark handed over the report: "These cases involve some casino gamblers and regulars. The victims all seem to be gamblers with bad backgrounds. The cause of death in the recent cases is similar—fatal wounds to the head and heart, and the murderer used extremely cold-blooded methods. No one has witnessed the murderer, and all the cases occurred in dark alleys and hidden locations near the casino."

Lin En flipped through the report in his hand, his brows furrowed slightly. "This was a premeditated murder, not a random act of violence. The murderer acted extremely cautiously. These gamblers are clearly not innocent people and may be involved in some underground activities."

"Yes, analysis shows that these victims seem to have been involved in illegal gambling or had some kind of improper relationship with the casino's owner," Mark continued. "But the Las Vegas police investigation is currently progressing slowly. It seems that the murderer is very skilled at covering his tracks."

Lin En closed the report and took a deep breath. "This isn't a simple matter. Las Vegas is a gambling city, after all, and the underground forces are complex and intertwined. If these cases involve casinos or underground gangs, we must rush over to investigate as soon as possible."

Mark nodded. "Yes, Lynn. The police haven't made much progress in their investigation these days. Maybe we can help them break the deadlock."

Lin En pondered for a moment, then stood up and said, "Let's leave immediately and head to Las Vegas. Prepare all the information and leave at any time."

A few hours later, Lynn and Mark boarded a flight to Las Vegas. This case may seem ordinary, but Lynn knows that there may be a more complex dark force behind it. Whatever the murderer's motive, they must find the truth.

The plane landed at the Las Vegas airport, and Lynn and Mark quickly went to the crime scene provided by the police. The streets of Las Vegas were still bustling with people, but behind the bright lights and feasting, there was filth and corruption.

The first place they arrived at was a place called the Golden Eagle Casino. The casino's ornate decorations and dazzling lights were dazzling, but Lin En's gaze remained calm. He knew that hidden behind this luxury and hypocrisy was a mountain of evil.

"Is this where the crime happened?" Lynn asked.

"Yes," Mark nodded, motioning for Lynn to follow him. "According to the police report, the first murder occurred in a dark alley near this casino. The victim was a gambler who had been gambling there for years. During the police investigation, they found his body discarded next to a garbage dump. It was clear the murderer didn't want to leave any traces." (End of Chapter)
