The Golden Great Deduction Technique

The United States, New York, York Academy of Science and Technology High School.

The school wasn't particularly famous in this enormous American city, which covered about 1,214.4 square kilometers, nor did it have the countless celebrities that were impossible to keep track of.

Feeney had chosen to study here for one simple reason: it was the closest school to home, and it had the best facilities.

"Sigh, looks like there's only a year left..."

Feeney murmured under his breath, a faint trace of worry between his brows. He crossed the soft, vivid green lawn, planning to take a shortcut to the school entrance.

"Sigh!"

Watching the constant stream of people at the school gate, Feeney couldn't help letting out another long sigh. In just one more year, the world would begin to undergo drastic changes in the open—changes beyond the imagination of most people.

"I'll say this one last time: I don't want to go out for a drink with you, so please stop bothering me here, okay?"

Just then, a familiar voice, tight with anger, reached Feeney's ears. He turned and saw a tall, burly man and a group of people pestering a beautiful girl not far from the school entrance.

The girl had long flaxen hair, delicate features, a high nose, and amber eyes now filled with impatience.

When Feeney saw her, his expression changed. He hurried over, shoved the burly man aside, and stepped in front of the girl. "Brian, what are you doing?" he asked in a deep voice.

Carson Brian was the Basketball Team captain. He seemed to have both good looks and skill on the court, and was something of a big shot at school, well liked by many. Feeney couldn't say he knew him well, but at least he recognized him.

"Feeney Helsay!?"

The burly man regained his footing and stared at Feeney in surprise. Then, with a cheeky grin, he said, "Hey, Helsay, this doesn't concern you, does it? I just wanted to get to know the young lady behind you."

"Feeney!"

Behind Feeney, the beautiful girl who'd been harassed called out in delight, making it clear to Carson that the two of them knew each other.

"She's my sister. Does that make it my business?"

Feeney replied coldly. Carson was much bigger than him, whether you looked at his height or his muscles, but Feeney wasn't the least bit afraid.

"Your sister!?"

Carson was taken aback, apparently not expecting that. His expression turned a little awkward. His teammates hadn't expected it either, and by now a crowd of curious students had gathered around them.

Under Feeney's cold gaze, Carson couldn't help taking a step back. When he noticed his companions staring at him in surprise, he immediately felt humiliated. He stepped forward again and said rudely, "How was I supposed to know she was your sister? Besides, I only wanted to invite her out for a drink."

"Are you deaf? Didn't you hear her say no?"

Feeney stared straight at Carson without fear. He had never been one to look for trouble, but that didn't mean he'd let someone walk all over him without saying a word.

"Feeney, forget it. Let's go."

The girl tugged at Feeney's clothes. Seeing more and more people gathering around them, she clearly didn't want to make a scene.

"Be careful. I think you're definitely going to trip if you walk like that."

Feeney glanced at the crowd. He didn't want to cause a scene in front of so many people either. He stared intently at Carson and said in a flat tone, then turned and led the girl out of the crowd.

Behind them, Carson stared blankly for a moment after hearing Feeney's words. He turned toward his teammates, about to ask, "What did he mea—"

Before he could finish, he tripped over his own feet and crashed heavily to the ground, splitting his lip. Blood streamed from the wound. It wasn't serious, but he looked miserable.

The crowd jumped in surprise. A few girls even screamed. The girl, who Feeney was leading away, heard the commotion and turned around to see the accident.

The two got into a car. In the driver's seat, the girl fixed her large amber eyes on Feeney, full of curiosity, and asked, "What was that about back there?"

"Murphy's Law. Whatever can go wrong will go wrong. If you're worried something might happen, it's even more likely to happen."

Feeney shrugged and made up an explanation with a straight face.

"Bullshit!" The girl looked unconvinced. "Feeney, I may not have gone to college, and my grades may not be as good as yours, but that doesn't mean you can fool me like I'm an idiot."

"Tsk." Feeney curled his lip and said nothing. That only made the girl angrier. She reached out and grabbed his ear, threatening, "Are you going to tell me or not? I'll tell Mom and Dad about your drinking if you're not careful."

"Okay, okay. Let go first."

Feeney hurriedly gave in, then muttered under his breath, "You always use that to threaten me. If you hadn't wanted to try that stuff and forced me to come with you, would I have drunk it?"

Feeney really didn't know what to do with his sister. If he'd known it would be like this, he should've chosen a younger sister instead.

Carson's fall just now had nothing to do with Murphy's Law. It was one of the abilities Feeney had gained after coming to this world.

Feeney hadn't originally belonged to this world. He had no idea how he'd ended up here. All he knew was that when he woke up, he'd become a baby who could only wail and couldn't even talk.

Fortunately, he hadn't come here empty-handed. As soon as he crossed over, he discovered that he'd brought along a seemingly powerful system that could draw various skills from different anime.

"Description: Magic that alters reality according to one's own thoughts"

Mind-to-Mind Success was the simplest way to sum up this ability. When Feeney first drew it, his excitement had been impossible to put into words. He'd wailed all night, imagining all kinds of wonderful futures, and left his parents with enormous dark circles under their eyes the next day.

But once Feeney had calmed down, he realized things weren't so simple. The ability didn't seem to work. He tried thinking about growing up right away, but after an hour, he hadn't grown a single hair. Of course, maybe he had and just hadn't noticed.

That was when he hurried to study the system again and realized it only handled drawing skills. Using them still depended on the individual.

So the reason he couldn't use the skill was himself.

The feeling was like falling from heaven back down to earth. It wasn't quite a fall into hell, because he knew that even if he couldn't use it now, he'd find a way someday. The wonderful future he wanted could still come true.

After realizing the skill didn't work, Feeney set the Golden Great Deduction Technique aside for the time being and began studying the so-called Extraction System, a name he'd come up with himself based on its function.

After all, the system was extremely simple. Apart from the draw function, all it had was an Experience Bar that seemed empty. Before he drew a skill, it had been full.

Clearly, he'd have to wait for it to fill up again before drawing another skill. He tried all sorts of things, but aside from a tiny amount of experience gained naturally, nothing seemed to make it grow.

Until that unexpected incident.
