1950s: After transmigrating into a capitalist, I relied on military industry to achieve a comeback.

The next morning, the first formal class of the refresher course was about to begin. The classroom was bustling with noise, and the air was filled with the smell of chalk dust. The three students from dormitory 117—Gao Jianguo, Song Siming, and Chen Mo—walked in right on time, their faces not looking too good.

Especially Song Siming, with two big dark circles under his eyes, clearly hadn't slept well last night because of the "Fourier transform". At this moment, his gaze towards Lin Jiaoyue was extremely complex: there was resentment, shame and indignation, and a trace of unconcealed awe.

The students in the classroom were mostly young and middle-aged men in their mid-twenties, dressed in dark blue work clothes from various factories or faded old military uniforms, and they all sat in a very unrestrained manner.

Lin Jiaoyue's slender figure sat alone in a corner of the front row, wearing a slightly oversized Lenin suit and two braids, looking out of place and exceptionally conspicuous. It was like a little white rabbit mixed in with a pack of wild wolves.

"Hey, isn't this our little genius? Are you settling into living in the storage room?"

Although Gao Jianguo was a little hesitant, he absolutely couldn't back down verbally. His loud voice rang out in the slightly noisy classroom, carrying a clear sense of provocation.

He walked to the seat in front of Lin Jiaoyue, deliberately dragged the chair with a loud "rip," and plopped down. His tall figure was like a wall, almost blocking all of Lin Jiaoyue's view.

"Comrade Xiaolin, this military industrial site isn't a place for kids to play in the mud. If you don't understand Professor Sun's lecture later, don't cry. Your brothers won't have any candy to coax you then."

A burst of laughter came from the surrounding area.

Song Siming, standing beside him, adjusted his glasses, pursed his lips, and remained silent, but the scrutiny and lingering resentment in his eyes were undisguised. Yesterday was a coincidence, it must have been a coincidence!

Chen Mo, meanwhile, crossed his arms and leaned against the radiator by the wall, watching coldly from the sidelines.

The other students in the classroom were also drawn to the scene, some curious, some scrutinizing, and some just watching the spectacle. Everyone had heard that a sixteen-year-old girl had transferred to the class and was even living in the storage room, and they were all waiting to see this "veteran bullying the new recruit" show.

Under everyone's watchful eyes, Lin Jiaoyue slowly and methodically closed the Russian textbook that was spread out on the table, even carefully smoothing out the creases at the corners. She raised her head, her almond-shaped eyes showing no sign of panic, but rather a calmness that seemed to see through everything.

Just as I was about to offer Comrade Gao Jianguo some "technical advice," suddenly—

"Ring ring—!!!"

The sharp, urgent school bell rang suddenly, breaking the tense atmosphere in the classroom.

Almost simultaneously, the heavy wooden classroom door was pushed open.

An elderly professor with gray hair, wearing a faded Zhongshan suit, walked in with steady steps, carrying lecture notes. He was thin, but his back was ramrod straight, and his sharp gaze swept across the room, exuding an air of authority without anger.

The classroom fell completely silent; you could hear a pin drop.

Gao Jianguo abruptly shut his mouth, like a duck whose neck had been choked. He shrank back sheepishly and turned back to sit up straight. The old professor walked to the center of the podium, put down his lecture notes, and scanned the classroom with his gaze, finally lingering on Lin Jiaoyue for half a second.

His gaze then fell on the thick Russian original edition of "Mechanics of Materials" on her desk, a hint of surprise and amusement flashing in his eyes.

He cleared his throat, his voice loud and clear, full of energy:

"Welcome, students, to the 'Precision Machinery and Materials Engineering' advanced training program. I am your lecturer in theoretical mechanics, Sun Zhenbang. Without further ado, let's open to Chapter 1 of the lecture notes..."

Professor Sun didn't waste any time and went straight into the lesson.

All eyes were subtly drawn to the slender figure in the corner. Everyone knew Professor Sun liked to call on students during class, and this "connected student" was in for trouble...
