The Artificially Genius Doctor
Battle Between Hackers

The rain fell gently outside the cafe, watering the plants that were almost withered due to the heat of the afternoon. The gurgling sound of water creates a soothing musical backdrop. Street light bounces off puddles, creating playful reflections on wet pavements. Inside, the aroma of freshly brewed coffee blends with the rain, providing a warm and soothing atmosphere.

Rudi took a sip of his coffee, his eyes fixed on the laptop screen that showed a row of codes. Elsa, with her black hair neatly tied back, was putting in some instructions. The light from laptop screens reflects blue light on their faces, providing a contrast to cafe lighting that tends to be dim and warm.

"Last stage, Elsa," whispered Rudi, keeping her voice low. "We almost made it."

Elsa held her breath. "Yes, just need a little more. I hope we're not detected."

Rudi raised his shoulders, his eyes focused on the screen. "Just calm. With the firewalls we've installed, they won't notice."

Elsa tilted her head to the side, her eyebrows seriously linked. His lips moved as if whispering on the screen, entering the last command. Suddenly, a pop-up appears, displaying the words "Access Accepted".

A big smile appeared on Rudi's face. "We made it!" patting Elsa on the back.

However, just then, a notification appeared on their screen, telling them that there were other hackers trying to access the same system. Elsa and Rudi look at each other, both realizing that they are not alone.

"Who is he?" hiss Elsa, her eyes widened to see the speed of the hacker who almost matched them.

"Either," Rudi muttered, his fingers danced over the keyboard, trying to block the hacker's access.

Amidst the panic, the door of the cafe opened quickly, and a man in a black leather jacket with blindfolds out of nowhere, walked in and sat down at the table next to them. He seemed to not care about the existence of Rudi and Elsa, but the two friends could feel something was not right.

Elsa, in a quick motion, closed her laptop and whispered to Rudi, "We have to go. I have a bad feeling."

Rudi nodded and the two stood up, trying to leave without attracting any attention. However, suddenly the man in the leather jacket greeted, "Not bad for beginners."

The two companions stopped, looked at each other, and Elsa asked in a trembling voice, "What do you mean?"

The man just smiled mysteriously. "You are not alone in this game. Be careful, the virtual world is more dangerous than you think."

Picking up their laptops and luggage, Rudi and Elsa rush out of the cafe, leaving the mysterious man with his enigmatic smile. The once gentle rain, had now turned into a torrential rain, watering them as it stepped out. However, the two were too focused on the incident just now to care about the soaking wet that stuck to their clothes.

After passing through some drenched streets, Rudi and Elsa take refuge under an old bookstore roof on a street corner. His signboard had already faded by time, showing the classic books in the front window. Rudi tried to calm her breath, while Elsa looked anxious, her eyes staring deep down the road, as if looking for a shadow that might follow them.

"We have to be careful, Rudi," said Elsa, her voice filled with worry. "That guy knows what we're doing. How did he know?"

Rudi sighed, her wet hair stuck to her forehead. "I don't know. But we have to find out. Who he is and what his purpose is."

Elsa shivered, either from cold or fear, or both. "Maybe we're too deep. Maybe this is a sign we should stop."

Rudi looked at Elsa sharply, "We can't stop now, El. We've found something big. We have to continue."

For a moment the two stared at each other, trying to find answers in each other's eyes. Elsa finally nodded slowly, showing her commitment.

They decide to return to Rudi's house, a place considered safe from spies. There, in the middle of a room full of computers and hacking equipment, they begin to investigate the mysterious man's digital footprint. Elsa works on the backend, looking for access through servers that the man might be hiding from, while Rudi focuses on the frontend, figuring out his identity through digital traces that might be left behind.

Hours passed without concrete results. But, Rudi, with his persistence, finally found something. A symbol, similar to the tattoo on the back of the mysterious man's neck. That symbol leads to a very closed and exclusive hacker-only online forum.

"Maybe this is where he came from" Rudi said, pointing the forum at Elsa.

Elsa watched closely, "This is one of the most secret forums, Rudi. Access is very limited. How do we get in?"

Rudi smiled faintly, "We have our own way, don't we?"

The two then embarked on a series of attempts to break into the forum. But, they know, they play with fire. The digital trail they left behind could be a clue for the mysterious man to find them back.

And sure enough, just as they were about to make it in, a message appeared on Rudi's screen, "Stop now or face the consequences." The message was not from the forum, but from the mysterious man.

Rudi and Elsa looked at each other, feeling a very real threat. But both know they must move on, despite dealing with dangers that may threaten their lives.

"We have to think" Rudi said in a low voice. "The man is definitely not an ordinary hacker. He has abilities we don't know."

Elsa nodded, "I know. I felt it when we tried to get into the forum. There's a kind of digital defense I've never seen before."

Rudi approached Elsa and stared at the screen. "We need help. There may be people out there who know more about this symbol or the forum."

Elsa looked at Rudi doubtfully, "You sure? Who can we trust? Maybe this guy's got eyes everywhere."

For a moment the two were immersed in each other's thoughts, contemplating every possibility. Rudi thinks of his acquaintances in the hacking world, while Elsa thinks about her network of contacts in the IT world.

Suddenly, Elsa patted him on the forehead, "I have an idea! What if we find out who made the digital defense? Every code has a digital signature. Maybe we can track him."

She smiled, "That's a good idea! Let's start."

They worked together, digging deeper into the defensive codes they encountered. Hour after hour passed. They almost give up when Elsa finds something interesting.

"Wait a minute... This..," said Elsa while zooming in on a piece of code. "Look, there's a pattern here that I recognize."

Rudi watched closely, "This is Haris' digital signature. He's one of the best hackers I've ever known. Why is he involved here?"

Elsa looked at Rudi in surprise, "You know him?"

Rudi nodded, "Yes, we worked together first. But he's gone and no one knows where he's going. But why is he working with the mysterious man?"

Suddenly, the lights in the apartment went out, and everything went dark. The sound of footsteps could be heard in the corridor. Rudi and Elsa looked at each other, sensing the approaching danger. Quickly, Rudi pulls Elsa down the table, hoping the shadows lurking outside don't find them.

In the dark, their heartbeats were racing, not knowing what would happen next.

Rudi and Elsa held their breaths, listening to the approaching footsteps. But then, a familiar voice for Rudi sounded behind the door. A quiet but authoritative voice.

"Rudi's? Elsa? Are you guys there? It's me, Haris."

Rudi immediately got up and opened the door. Before him stood Haris in a long black robe, his face illuminated by the moonlight coming in from the corridor window. Elsa followed Rudi and stood beside him, with a look of suspicion.

"Daris? Why are you here? And why are you involved with that forum?" Ask Rudi.

Haris took a deep breath, "We need to talk. But not here."

Rudi and Elsa follow Haris to the roof of the apartment, where the cool night air welcomes them. The city looks beautiful with its lights.

"Actually, I'm not your enemy" Haris began to explain. "I became part of that forum not out of my own desire. They kidnapped my sister and forced me to work for them. But I'm always looking for ways to fight from the inside and help you."

Elsa looked relieved, "So, we're actually on the same side?"

Haris nodded, "Yes. I know you guys are the right people to help fight this forum. Together, we can stop what they're planning."

With the information from Haris, the three of them started planning a counterattack. Haris gave details about the digital defences that were on the forum, as well as telling them about its weaknesses. Elsa, with her genius in computer science, begins designing programs to attack and take over the forum.

Meanwhile, Rudi thought about how to free Haris' sister and everyone who was the victim of the forum. "We have to work fast. Every second is precious."

It was time to execute their plan. With perfect coordination and each other's genius, they began to attack the forum from various sides. Elsa deftly penetrated the defense of the forum, while Haris gave step-by-step instructions.

Rudi uses his medical skills to help the injured. With the help of the AI they once created, they get important information about the location of Haris' sister and other victims.

After hours of digital battles, they finally succeeded. The forum was successfully hacked and controlled. Haris' sister and all the other victims were rescued.

The three of them, sitting side by side, stared at the glittering city below them. They have won. However, they know that this is only the beginning of their next adventure.
