The urgent knocking at the door reflected Oliver Scott’s current mood. The door quickly opened. In Marcus Shaw’s view appeared a figure with a head of messy short hair, looking exhausted, a toothbrush in his mouth foaming with suds, and a loose T-shirt sliding off one shoulder, revealing his collarbone. The two popular guys known for attracting attention on campus were now both in their own messy states. Placing a hand on the door frame, Marcus, with a toothbrush in his mouth, furrowed his brows and glanced at Oliver twice, unclear words asking, "What’s up?" Ignoring everything else, Oliver raised the drawings eagerly asking, "Did you finish these last night?" After glancing at the drawings, Marcus didn’t immediately react and simply replied, "Nope." Oliver was taken aback momentarily, then asked, "Do you have a sleepwalking problem?" "You’re the one sleepwalking..." Marcus mumbled, glancing toward a certain room, speaking listlessly, "Isn’t there someone else next door?" The remark was like waking Oliver from a dream. Oliver quickly turned his head to look at Nora Scott’s room, but the door was tightly closed, and no part of their commotion had elicited any reaction. Pulling out his toothbrush, Marcus asked, bewildered. "The drawings! It’s a perfect restoration!" Usually calm and composed, Oliver spoke with excitement and elation, shoving the drawings right in Marcus’s face. Marcus quickly dodged, reaching out to catch the drawings. Glancing down at the brand-new drawings, he too was somewhat astonished. Every part was drawn in detail, mostly matching what they had sketched, but the mechanical sections were completely different... Even as an amateur like Marcus, seeing the mechanical sections of the drawing, could immediately determine: This is the original mechanism! The fit was too perfect. "Is your sister actually pursuing a career as a celebrity as a side gig?" Oliver leaned closer to look at the drawings, messing his hair up in Marcus’s face, whom he didn’t notice, and marveled, "This level is certainly professional." Marcus was momentarily dumbfounded. He recalled that Evelyn Easton often bent over drawings, studying all night, which he found meaningless, just dull and boring. However, whenever Evelyn mentioned the "Ancient Mechanism Technique," he could feel her pride and excitement, an innate passion that naturally emerged. Seeing Marcus’s delayed response, Oliver nudged his shoulder, "What are you thinking about?" Marcus snapped back and replied indifferently, "Nothing." Taking a step back, Oliver glanced again at a certain room, asking, "What time does your sister usually wake up?" Marcus slapped the drawings back into Oliver’s arms, saying expressionlessly, "I’ve only stayed here for two nights, last night was the second." Oliver was utterly at a loss. So, these siblings really aren’t familiar with each other? Failing to continue the conversation, Marcus returned to his room to freshen up, emerged a bit later, and came out with his phone. "She messaged me at six, she left early. Told us to have breakfast next door, someone prepared it." Oliver poked his head out of the bathroom, his hair wet and still with droplets on his face. Marcus patiently repeated the information. Oliver asked in surprise, "Next door?" Marcus nodded, "A god-like neighbor." Oliver shook his head, water droplets flung from his hair in all directions, agreeing, "Ah, a god-like neighbor." At Fenton University, in a certain laboratory. When Joseph Sutton returned from the cafeteria, he saw Nora still sprawled on the table, with a coat draped over her and what seemed like unruly strands of hair sticking up or scattered across the table, lacking any form of beauty. He placed the breakfast he brought back beside her, saying, "Breakfast." Several seconds later, Nora responded sleepily. With a tap of his fingers on the table, Joseph lowered his gaze, looking through his black-framed glasses at her hair like weeds, sighing with resignation, "I thought you came so early to work overtime." "Stayed up all night." Nora sat up sleepily, eyes half-open, her fair face marked with traces of sleep. She grabbed a pile of drawings and shoved them into Joseph’s arms, "The drawings are done; take a look." Looking at the stack of drawings in his hands, and recalling Nora having nothing on her person when they parted the night before, Joseph couldn’t help but mutter in his heart, "Monster." After days of theoretical research and a night’s work, to settle on the drawings... This pace is just incredible. Pushing up his glasses, Joseph carefully reviewed her drawings and, after reading them one by one, his thick eyebrows nearly knotted together, "Time is so tight; are you still planning to show off by creating two mechanical forms?" Nora’s drowsiness lingered in her eyes, but she leisurely replied, "There’s no fun if I don’t show off." If she does it, she does it astonishingly. —This was Nora’s principle. Nora, with anything worthy of her time and effort, essentially needed to find "fun" as a precondition. Without a specific clear purpose, she would be perfunctory and lack enthusiasm in whatever she did. "Joseph Sutton gave in, sighed, ’A month, is that enough?’" "’No need for a month,’ Nora Scott plunged a straw into her soy milk cup and lifted her eyelids, ’At most another week.’" Nora leaned back in her chair, took out a meat bun from the breakfast bag, and said, "Help me make a simulation model. I plan to use lightwood, so calculate the overall weight, and then add the power system, control system, and confirm operability." Joseph Sutton glanced at her, "Don’t you usually skip modeling those things? You’ve said before, even if you design a mechanical secret room, you can clearly calculate even the fingernail-sized mechanical parts using your brain alone." Nora took a bite of the meat bun and looked at him feigning surprise, "Those things can fly?" She always outdoes him in their playful banter. Admitting defeat, Joseph clutched the blueprints, walked to the computer, pulled out the chair, and sat down. Nora’s expertise lies in Ancient Mechanical Techniques, particularly the primitive ones using natural control, and she isn’t as adept at software and modeling as he is. Sir Sutton had repeatedly instructed Joseph to help her, and with Nora’s task pressing, he had no choice but to comply. As the computer booted up, Joseph asked, "Why have you suddenly taken an interest in drones?" After finishing a meat bun, Nora slightly tilted her head, picked up a boiled egg, and lazily replied, "For someone." "Last night’s person?" With a single syllable, there was clearly no denial. Your way of flaunting your affection is truly unique. Just as Joseph Sutton felt a bit annoyed thinking about Pedro Langley keeping Nora awake all night, his mood soured, and even the freshly peeled egg seemed tasteless. Lightly biting into the egg white, Nora chewed slowly, swallowed, and suddenly asked, "Can you hack into someone’s phone?" "I study programming and focus on drones." Joseph Sutton spread his hands and suspiciously stared at her, "What are you planning?" To hack into Pedro Langley’s phone, change his WeChat avatar, and delete his backup pictures. No reply came; Joseph recalled something and said, "Don’t you know a hacker?" "In the army, no chance." "He even joined the army?" "Specifically recruited." Joseph Sutton felt inexplicably annoyed. Nora’s hacker acquaintance had crossed paths with him before. During a chat, some unpleasant words were exchanged, and later, that scoundrel hacked their lab’s computer, forcing their team and mentor to watch ten minutes of awkward and ugly animated dances. Fortunately, it was just a prank, with no data loss, and since the hacker later helped fortify their firewall for free, it was best left unspoken. For this reason, Joseph Sutton always felt Nora’s choice of friends was extremely unreliable. Nora finished a tasteless boiled egg, then pushed away the rest, not feeling any appetite, draped her coat over her shoulder, and continued to sleep on the desk. Afternoon, four o’clock. After a whole day of battling, Marcus Shaw and Oliver Scott finally assembled all the components according to the blueprints. A few planks had exhausted them completely. Exhaling deeply, Oliver Scott shoved all the parts to Marcus Shaw’s side. Marcus Shaw flexed his fingers, slowly exhaled, and then started assembling the Mechanical Box according to the blueprint. All the wooden pieces had mechanical linkages, with no need for glue. It meant once the components formed, they could be hand-assembled into a complete form. But such design significantly tested the designer’s skills. Assembling, Marcus couldn’t help but grumble internally: Who’s the maniac that designed this, with nothing better to do but add so many tricks to a box? "I slept very lightly last night, heard some movements but wasn’t sure..." Oliver Scott, sitting cross-legged across the floor, watched Marcus assemble and spoke slowly. Marcus paused, "If you’ve got something to say, spill it." After some hesitation, Oliver cautiously asked, "Let me ask first, did your sister study this Mechanical Box beforehand?" Marcus could be certain of this. He had brought the Mechanical Box over twice, and although Nora looked at it both times, the combined time wasn’t even two minutes. Two minutes... what’s there to "study"? Oliver scratched his head, drooped his eyes, and said, "Did you ever consider your sister might actually be a genius?" Marcus frowned, "What’s that supposed to mean?" Oliver spread his hands, "Last night, I heard her in the living room, the time gap, at most ten minutes." "If she didn’t spend the whole night drawing the blueprints, then it must have only been completed in those ten minutes." Oliver analyzed with an incredulous expression. This was the most logical guess he could come up with. Oliver then used an elimination method, saying, "Based on your relationship with your sister, I’d guess she wouldn’t spend the whole night drawing these blueprints for you."
