Doomsday Mechanic: My Train Can Be Modified Infinitely

Chapter 17 Blueprints



Chapter 17 Blueprints

Inside the technology center's carriage, Lin Luo'er was asleep, her face resting against the open circuit diagrams, her breathing shallow and even. The lamplight cast a soft, warm glow on her face, and her long eyelashes cast tiny fan-shaped shadows beneath her eyelids. Scattered around her were draft papers filled with derivations, and a drawing pencil had rolled to the edge of the table, its tip broken.

Wang Zhengyang pushed the door open and walked in, his footsteps very light, but the hinges of the metal car door still made a slight friction sound.

"Engineer Wang!" Lin Luo'er sat up abruptly, rubbing her sleepy eyes. When her gaze fell on the dark stain on Wang Zhengyang's left shoulder where his clothes were torn, her sleepiness vanished instantly. "You're injured!"

"Skin and flesh injuries, no impact on function." Wang Zhengyang connected the hard drive to the isolated interface of the analysis computer with smooth and steady movements. "Transaction complete, core data obtained."

The hard drive indicator light began to flash rhythmically, and the data stream was imported into the local storage array through a military-grade encrypted channel. A hierarchical file directory tree popped up on the screen in sequence—"Thunder Matrix" Energy Deflection Shield System (98.7% completeness) and "Earth Pulse" Adaptive Heavy Chassis (76.4% completeness).

Lin Luo'er leaned closer to the screen, her eyes growing brighter under the desk lamp, like stars ablaze: "So many documents... This is the complete system architecture document... Wait, the design of this liquid metal cooling circuit is ingenious! Using gallium indium tin alloy as the medium, combined with microchannel heat dissipation and phase change thermal storage materials to buffer thermal shock..."

Her excitement noticeably faltered for a moment when she saw the mechanical blueprints for "Earth Pulse".

The screen displays complex 3D exploded views and 2D engineering drawings: meshing relationships and tolerance tables of gear transmission systems, topology and pressure-flow curves of hydraulic suspension pipelines, stress distribution cloud maps and failure mode analyses of composite armor layers... These belong to the fields of heavy machinery engineering, fluid mechanics, and materials mechanics, and there is a professional gap between them and her major in hydroponics and air circulation regeneration systems.

She strained to look at the blueprints, her brow furrowed slightly, her lips unconsciously pursed, and her fingers traced names in the air, trying to understand the complex mechanical tolerances and dynamic load transfer paths. She could grasp some of the basic principles, but that deep-seated, natural familiarity, like breathing, was missing. It was like asking a top-notch software architect to interpret the seismic design drawings for a large bridge project—they could read them, but it was laborious, and it was difficult to immediately generate creative insights.

Wang Zhengyang caught this detail out of the corner of his eye.

He pulled up the automatically generated technical file integrity report and turned the screen to Lin Luoer: "Your task priority has been adjusted. Concentrate all computing power on verifying the equations of the 'Thunder Matrix.' Within twenty days, I need you as my assistant to help me verify the first functional prototype of the simplified shield system. Objective: Using civilian-grade components that we can obtain through conventional industrial channels, achieve a basic electrostatic deflection layer with an effective coverage area of ​​not less than three square meters, a theoretical deflection efficiency of not less than 12% for kinetic energy projectiles, a continuous operating time of more than fifteen minutes, and system power consumption controlled within 15 kilowatts."

Lin Luo'er raised her head, her eyes brightening again, but then a hint of hesitation flashed across her face: "Then... 'Earth Pulse'..."

"The mechanical structure of 'Earth Pulse' is being handled by Engineer Chen's team." Wang Zhengyang brought up another project management interface, which already listed a detailed breakdown of the work processes. "The missing intelligent control algorithm and sensor fusion module require you as my assistant to complete the second priority task after the first phase of the shield system's verification. Now, use your expertise where it is most needed and where you can best leverage your core value."

He paused, then added, his tone still calm but with a touch more warmth: "The team needs everyone to be in the position that best suits them. Although it's interdisciplinary, your extensive basic research experience in the lab can help me become the driving force behind this research breakthrough."

Lin Luo'er paused for two seconds, then nodded vigorously, her ponytail swaying gently behind her head, the ends brushing against the collar of her work clothes: "Understood! I'll start refining the calculation plan right away!"

But her gaze unconsciously drifted back to Wang Zhengyang's shoulder. The bloodstains had dried into dark red lumps on the dark tactical jacket, with fresh traces of seepage at the edges, spreading between the fabric fibers.

"Your wound... at least let me treat it again, okay?" she said softly, turning around to take a standard German field medical kit from a storage cabinet in the corner of the carriage. The kit had a faded cross on the outside. "I took Red Cross first aid training in college, and later I also studied battlefield first aid and trauma treatment on my own... I should be able to handle it quite professionally."

Wang Zhengyang glanced at her sideways. His rational analysis was that treating his own wound would take twelve to fifteen minutes, including disinfection, cleaning, dressing, and bandaging; letting her handle it would likely take eighteen to twenty minutes, but this would save him time for more pressing technical planning tasks. At the same time, this was also an opportunity to observe her meticulousness, aseptic technique, and emergency response capabilities.

"Okay," he said briefly, and began to unbutton his shirt.

Lin Luo'er's cheeks flushed visibly, spreading from her ears to the side of her neck. She clearly hadn't expected Wang Zhengyang to agree so readily. She hurriedly opened her medical kit, taking out sterile gloves, iodine wipes, hemostatic powder for external injuries, a new type of hydrocolloid dressing, and self-adhesive elastic bandages. For a moment, she didn't know where to look.

Wang Zhengyang had already deftly removed his tactical jacket and the black work vest underneath. His lean upper body was exposed in the light of the carriage's overhead lamp; his muscles were well-defined but not overly exaggerated, and his skin was a wheat-colored tan from years of outdoor work, dotted with several old scars—some were thin white marks left by sharp objects, some were areas of pigmentation from burns, and one was a dent that looked like it had been grazed by shrapnel. The wound on his left shoulder was about five centimeters long and three millimeters deep, a typical cut from a combat knife, with clean edges but some redness and swelling.

Lin Luo'er forced herself to focus entirely on the wound. She put on sterile gloves, her movements slightly clumsy but still within the proper procedure. Using tweezers, she picked up a cotton swab soaked in iodine and began wiping the wound in a spiral motion from the center outwards, wiping each area only once to avoid cross-contamination. "It might sting a little… iodine is less irritating than alcohol, but still…"

"Continue." Wang Zhengyang's voice was steady, and his breathing rhythm remained unchanged.

After thorough disinfection, she sprinkled a layer of a new type of coagulation and antibacterial powder—a military-grade product that simultaneously possesses hemostatic, antibacterial, and granulation tissue-promoting properties. Then, she applied a hydrocolloid dressing specifically designed for mobile joints, ensuring the dressing's edges adhered tightly to the healthy skin without gaps. Finally, she secured it with a self-adhesive elastic bandage using a standard figure-eight method, ensuring the dressing's stability without restricting shoulder joint mobility.

Throughout the procedure, her fingers were incredibly dexterous, applying even and moderate pressure to the dressing and controlling the tightness of the bandage perfectly—ensuring secure fixation without hindering local blood circulation. She held her breath the entire time, only letting out a long sigh after completing the final step, her forehead already beaded with sweat, her expression as focused as if she were soldering a microcircuit.

"Okay, all done." After securing the end of the bandage with medical tape, Lin Luo'er took a half-step back with a sigh of relief, only then realizing that she had been very close to Wang Zhengyang, close enough to see the fine pores on his skin and the contraction and relaxation of his muscle fibers.

Her face turned even redder, like a ripe apple. She quickly bent down to take off her gloves and tidy up the medical waste, her movements somewhat flustered.
