Washington D.C., West Side, inside a beautiful villa. Luo An eventually made the call to Caroline, but did it in front of Mona, with the mobile phone set to maximum call volume. "Good evening, Caroline." "Good morning, Luo An." Caroline yawned grandly on the other end of the line, her voice languid: "Did you forget about the time difference? I'm in the British Empire right now, it's five hours ahead of your place." Luo An raised his eyebrows, he indeed forgot about the time difference, but it was not important, he asked directly: "Mona said you were looking for me, what's up?" Mona, sitting beside him, gave Luo An a disparaging glance while folding her arms in front of her chest and quietly watching the phone. "It wasn't me looking for you, I said that just to tease Mona, it's amusing to see her angry." Caroline laughed heartily on her side of the call, while Mona's face gradually took on a darker shade on this side. Luo An twitched the corner of his mouth and quickly interrupted Caroline, asking: "Let's get down to business, if it's not you looking for me, then who is?" "It's not exactly looking for you, or rather, the person isn't seeking Luo An." Caroline's laughter slowly ceased as she explained: "They're looking for Brian." Some time ago, Caroline set up a company in the British Empire because the overall taxation there was lower than in Europe, and it also had the trade protections of the European Union. During the process of handling company matters, a very beautiful woman came looking for Brian, specifically by name. Upon hearing this name, Mona's eyebrows immediately furrowed, her hands clenched subconsciously, and she looked up at Luo An. The name Brian was one of the aliases used by Luo An when he led Mona and Caroline to Europe a while back, during the disappearance of her father Javari Evans, with the identity being that of a private detective. Back then, Luo An also used several other aliases such as Tom and Jerry. After successfully rescuing Javari Evans, the name Brian and others were completely abandoned, and Luo An's true identity was only known by four people: Mona, Caroline, Javari Evans, and Mrs. Hanover. Hearing the name Brian again today made Mona instantly tense; during that operation, they had made quite a few "good friends." Flashes of countless thoughts and contingency plans raced through Luo An's mind, but he maintained a calm demeanor, asking: "What does the person want to talk to me about?" "I don't know; the woman didn't say." Caroline yawned again and said: "But I did ask for you, she mentioned she could reimburse the plane ticket, and offer free accommodation." Mona's brows were tightly knitted as she looked up at Luo An, speculating: "Could it be that your real identity has been exposed?" "It shouldn't have been." Before Luo An could speak, Caroline's voice came again from the phone: "I checked the woman's identity; she is a descendant of an old noble family from the British Empire. Recently, several people in that old noble family died one after another, I suspect that she has come to seek Luo An's help, asking him to help solve the case, just like Sherlock Holmes from the novels." "Let's pretend this never happened." After a moment of contemplation, Luo An's eyes narrowed slightly as he said: "Brian is already dead, he has physically retired from being a private detective." Caroline laughed on the other end; she knew Luo An would choose this, but it was still necessary to inform him. After some idle chat, Caroline, who needed to catch up on her beauty sleep, took the initiative to hang up the phone. Mona, on the other side, looked worried. After setting the phone aside, Luo An reached out to embrace her, signaling there was no need to panic. Every problem has a solution like soldiers face enemies and embankments stop floods. However, simply doing nothing and waiting wasn't the best course of action. Therefore, Luo An asked Mona for her phone to call Javari to have him check the identity of the old noblewoman Caroline mentioned. "I'll do it! I'll call him!" Upon hearing this, Mona immediately took out her phone, ready to talk to Javari herself. After all, the previous rescue mission was for Javari, and Mona wouldn't agree without him putting in effort. Feeling guilty on the other end of the line, Javari agreed without hesitation to Mona's request for an investigation. But Mona still felt worried, and after further discussion, they decided that Javari would provide 500,000 US dollars to thoroughly investigate the matter. Seeing his daughter use her elbowing-out technique and being more worried about Luo An than herself, a heart-sinking Javari silently transferred 500,000 US dollars and then hung up the phone. The matter concerning Caroline was temporarily closed. There wouldn't be investigative reports coming out soon. Mona and Luo An had a brief chat, and as it was getting late, they stood up and went upstairs to rest. The next day, in the special investigative team's office area, Winslow took a leave of absence. The other members sat at their desks processing follow-up documents for the cases. Luo An, as the head of the investigative team, also sat behind a computer in his office, looking serious... but actually slacking off. During the lunch break, after having lunch, Reesi, Chenier, Mona, and Michelle gathered to chat about gossip. Luo An returned to his office, closed his eyes to rest, and at the same time, opened the system interface in his mind. [Nuclear Warhead Lost Case]For this, the system gave Luo An the rare evaluation of [Extremely Excellent], accumulating 6 treasure chests. After a rough transitional animation, the 6 chests opened to reveal: [Stamina Potion x2] [Hemostasis Potion x1] [Swiftness Potion x1] Afterward, upon opening the system inventory page, it currently held: [Stamina Potion x8] [Hemostasis Potion x9] [Swiftness Potion x8] [Regeneration Potion x7] [Sensitivity Potion x1] Content orıginally comes from NoveIꜰire.net [Painkiller Potion x8] [Feather Falling Potion x7] Still no sign of [Danger Perception Potion]. Potions like [Strength Potion] and [Swiftness Potion] seemed to be one-time use only, with their effects fading not long after consumption. But after each use, about 90-95% of the effect would dissipate, with a small portion of the effect permanently remaining within Luo An's body. Over time, Luo An's strength and speed were slowly but noticeably increasing. The [Stamina Potion] was also steadily increasing Luo An's stamina limit. Every weekend, Mona who played cards with Luo An would feel exhausted the next day and unwilling to get up. Additionally, the minimum requirement for active soldiers in the Eastern troops was to complete 45 standard push-ups in 2 minutes for passing, 60 was considered excellent, and 100 was a show-off. The highest recorded number of push-ups in the world was 2902 by a soldier from the East in a single bout. Luo An hadn't measured by time but going by the count, he once did 600 standard push-ups in a row in his villa without feeling tired. If it hadn't been for Mona entering the room to bring him fruit, Luo An felt he could have done another 600. Then there was the most stamina-consuming long-distance running. Luo An tried the treadmill in the villa, completing 10,000 meters in 39 minutes. Though far from the world record of 26 minutes and 11 seconds for 10,000 meters, Luo An had not received any professional long-distance training and ran solely based on feeling. Moreover, he didn't feel particularly tired or dehydrated and could have continued. This meant that over short distances and times, he possessed excellent speed and explosiveness, and for long-distance sprints, his stamina was far superior to many others. As Luo An continued to reflect on the benefits of other potions to himself, the office door was knocked on and pushed open. Reesi swayed an item in her hand: "Luo An, you have an invitation."
