In the central dome hall of the String Light Research Institute, sunlight filtered through smart‑tinting glass, casting a uniformly warm glow that seemed precisely calculated. Today wasn't a nationally mandated holiday, yet here, it felt more solemn and hopeful than any holiday. The annual "Inheritance Day"—this informal ceremony jointly established by Mozi, Yue'er, and Xiuxiu—had, over the years, evolved into one of the most symbolic events within the institute and even across China's entire tech community.
There were no cumbersome procedures, no lengthy leadership speeches. In the center of the hall stood two seemingly ordinary solid‑wood chairs, whose curved backs incorporated unique designs that blended ergonomics with Eastern aesthetics. In front of the chairs rested a low circular stone platform, its surface polished to a mirror‑like smoothness, faintly reflecting the contours of the dome.
Yue'er and Xiuxiu walked side by side into the hall. Neither wore formal attire; Yue'er was in a deep‑gray Chinese‑style standing‑collar top paired with simple black trousers, while Xiuxiu wore the institute's usual light‑blue work clothes, only ironed exceptionally neatly. Their arrival caused no commotion. Gathered around them were young researchers from various fields of the institute, invited students from university special‑talent programs, and outstanding contributors selected from the open community of "String Light Cloud Brain." These youthful faces, eyes clear, held the purest thirst for knowledge and unreserved longing for the future.
Yue'er and Xiuxiu sat down on the two wooden chairs, their gazes calmly sweeping over this young "new wave" before them. They saw familiar faces—the twenty‑year‑old mathematical genius who had assisted Yue'er in stabilizing the mathematical framework during the "Zero‑Out" crisis; the young engineer in Xiuxiu's "Root Technology" team who had proposed an innovative error‑compensation algorithm, boosting the ultra‑precision machine‑tool performance by five percent; and many unfamiliar eyes that nonetheless sparkled with intelligence.
"Another year has passed." Yue'er spoke softly, her voice clearly reaching every corner of the hall through hidden amplification, not loud but possessing a tranquil power that could soothe restlessness. "Time flies. I remember the first 'Inheritance Day,' held in those temporary prefabricated buildings just after the institute was founded. Only about a dozen people were there; Mozi was still hustling for the first angel investment, while Xiuxiu and I—one drawing symbols on the blackboard that no one understood, the other staring frustratedly at failed light‑source data in the lab."
A ripple of good‑natured, understanding low laughter rose from below. Many young researchers had heard tales of those trailblazing years; those legends weren't just about the three founders, they also inspired them to persevere when hitting their own bottlenecks.
Xiuxiu took over, her voice relatively crisp, carrying an engineer's characteristic pragmatism: "Back then, our thinking was simple: we couldn't let others choke us, and we felt certain things had to be done, no matter how difficult. Our generation, standing on the shoulders of predecessors, stumbled forward amid blockades and catch‑up." She paused, her gaze growing distant, as if piercing through time to see the resolve when handing in her resignation in the Netherlands, the anxiety over repeated DUV light‑source failures, the long nights before the Extreme Ultraviolet lens thermal‑deformation challenge was conquered. "We paid a price, sweated, and shed tears. But we were lucky—we seized a tiny crack given by the era, used all our strength to pry it open."
Yue'er nodded slightly, her fingers unconsciously tracing the outline of a complex topological symbol on her knee. "The exploration of knowledge and technology is an endless long march. We, including everyone here, are merely a segment of this long river's flow. We may, at certain stretches, stir up somewhat conspicuous waves due to the terrain's undulations, but the river itself is eternal, ceaselessly flowing." She looked at the young faces below. "We stand here today not because we have climbed to the summit of knowledge—in fact, we recognize our own limitations and the vastness of the unknown more clearly than ever. We stand here because we are willing, and have the responsibility, to pass the still‑faint torch in our hands to you, whose eyes are brighter, whose steps are lighter, whose future is broader than ours."
No impassioned agitation, no hollow lecturing. Two women, in the plainest language, recounted their journey, acknowledged their limitations, and expressed their most sincere expectations. This candidness, instead of any ornate rhetoric, held a penetrating power that went straight to the heart.
At that moment, two young representatives stepped forward from the crowd. One was a girl from the Mathematics and Theoretical Physics Interdisciplinary Center, named Lin Xing, only eighteen, yet on the foundation of Yue'er's information‑geometric field theory, she had proposed a bold conjecture about "quantum spacetime‑fiber entanglement"—the leap and rigor of her thinking had amazed even Yue'er. The other was a young man from the Advanced Manufacturing Laboratory, named Chen Shi, twenty‑five, who had led the improvement of the micro‑capsule encapsulation technology for the "self‑repairing materials" proposed by Xiuxiu's team, enhancing its stability and response speed by an order of magnitude, demonstrating remarkable engineering implementation capability.
Lin Xing appeared somewhat shy, but when she raised her head to look at Yue'er, her eyes held unadulterated reverence and a kind of intellectual resonance almost like "I understand you." Chen Shi was steadier; his gaze toward Xiuxiu was filled with respect for technical authority, but even more with a confident, sharp "I can do better."
Yue'er slowly stood up and walked to the circular stone platform. Xiuxiu rose simultaneously, standing beside her.
Yue'er extended her hand; in her palm, she now held an object. It wasn't a physical torch, but a complex geometric structure generated by holographic projection technology, continuously morphing in form. At times resembling a rotating polyhedral crystal, refracting countless hues of logical light; at other times like an infinitely expanding Calabi‑Yau manifold, containing cosmic‑scale symmetry and mystery; then collapsing into flowing streams of mathematical formulas, each symbol seemingly alive, pulsing with the rhythm of thought. This symbolized the "Light of Mathematics"—the crystallization of pure reason and imagination, the key to understanding the underlying code of the world.
"Lin Xing," Yue'er's voice was gentle yet solemn, "I see your eyes seeking order in chaos, I sense that rare tranquility and curiosity you possess when facing the infinite. Mathematics is free—bound by no material constraints, its realm limited only by the boundaries of our imagination. But mathematics is also heavy—each of its truths often demands the most rigorous logical tempering and lonely vigil." She slowly offered out the morphing "light." "Now, I pass to you this questioning of truth, this way of thinking that transcends form and substance. Do not fear the heights of predecessors, for it is by standing on their shoulders that you glimpse farther stars. Nor be bound by existing paradigms; boldly doubt, construct, destroy and rebuild. Remember, the most beautiful formula is always the next."
Lin Xing took a deep breath, extended both hands, and with utmost solemnity—as if receiving not virtual light‑shadow but a weighty inheritance of thought a thousand pounds heavy. When her fingertips touched the flowing geometric structure, the "light" trembled slightly, then stabilized; its morphing seemed to grow more orderly, more full of intrinsic vitality. She nodded firmly, not uttering a word, yet the glistening tears and determined look in her eyes said everything.
On the other side, Xiuxiu also raised the "light" in her hand. That, too, was a holographic projection, but it displayed a beam of extremely focused, seemingly matter‑penetrating "solid light." Within this beam, one could see subtle, life‑vein‑like energy flows—sometimes manifesting the invisible ferocity of extreme‑ultraviolet light, sometimes exhibiting the mysterious yet coordinated linkage of quantum entanglement, sometimes simulating the precisely controlled paths of light on metasurfaces. This symbolized the "Light of Physics"—the spark where theory collides with reality, the staff transforming abstract laws into the power to reshape the world.
"Chen Shi," Xiuxiu's gaze was sharp and full of expectation, "I admire your 'feel' for materials, that talent for perfectly merging theoretical parameters with practical craftsmanship. Technology is concrete—it must face environmental noise, tolerate material imperfections, accumulate that minuscule yet crucial experience through countless failures. But technology is also romantic—it can ground ideas, make fantasies tangible reality." She offered the "solid light" to Chen Shi. "Now, I pass to you this obsession with precision, this creative passion for turning the impossible into possible. Don't be content with solving immediate problems; dare to challenge engineering limits, to define future standards. Remember, the most perfect device is always the next."
Chen Shi straightened his back, his hands steadily accepting the beam of "solid light." In his grasp, the beam seemed to grow more condensed, its edges sharper, as if ready to plunge into concrete manufacturing processes—to carve atoms, to weave the future. He replied in a low voice: "I will not fail this trust."
No ceremonial cannons, no thunderous applause. The entire hall fell into a peculiar silence. Everyone held their breath, watching this soundless yet immensely weighty transmission. Two outstanding members of the younger generation, holding lights of symbolic significance, stood there as if connecting past and future.
Yue'er and Xiuxiu stepped back, standing side by side, watching Lin Xing and Chen Shi, and behind them the crowd of young faces brimming with infinite potential. Their faces simultaneously revealed a complex, profound expression. There was contentment at seeing their painstakingly nurtured endeavor gain successors; relief in recognizing that the tide of the times was unstoppable; and a trace of subtle, wistful melancholy that the mission belonging to their generation was nearing a stage of completion.
But more than that, a serene, eternal sense of happiness flowed silently within both of them, converging.
Had their era ended? Of course not. Yue'er's mathematical universe continued to expand; Xiuxiu's technological frontiers were still advancing; Mozi's "New Continent" had just begun. They remained at the forefront of exploration, guiding the direction.
Yet, the baton of civilization had indeed begun to pass quietly. They were no longer lone pioneers fighting alone; beside and behind them had gathered a group of equally excellent, perhaps even more outstanding, fellow travelers. The path they had pioneered, the foundation they had laid, the sparks they had ignited were being taken up by a new generation, and would be carried to broader, more splendid horizons in ways they could not fully foresee.
This, perhaps, is the most moving aspect of inheritance. It is not mere replication, nor total replacement, but an extension of life, a propagation of spirit, a civilization's self‑renewal. The finitude of individual life achieves a certain transcendence through this extension, propagation, and renewal.
Yue'er turned her head slightly, looking at Xiuxiu. Xiuxiu also turned to look at her. Their eyes met, instantly understanding the unspoken resonance in each other's gaze. They recalled their own youthful selves, the moments of meeting and knowing each other, the countless storms and glories they had weathered together. From Princeton afternoons to Eindhoven decisions, from Shanghai trading rooms to challenge‑filled laboratories, from initial ideal collisions to today's inseparable "trinity"… all these memories, at this moment, became the deepest annotation to the scene of torch‑passing before them.
They exchanged a smile. That smile held the clarity that comes after weathering many trials, joy at witnessing growth, boundless trust in the future, and the unique silent accord and warmth that belonged to them alone.
Lin Xing and Chen Shi turned, facing all the young participants. The "Light of Mathematics" and "Light of Physics" in their hands shone in mutual reflection, as if foretelling a future innovation landscape where disciplinary boundaries would blur further and integration would deepen. Young energy, like the rising morning sun, filled the entire hall, illuminating the String Light Research Institute and even the path forward for human civilization.
The ceremony ended silently. The crowd began to disperse slowly; young students gathered around Lin Xing and Chen Shi, excitedly discussing, eyes burning with new flames. Yue'er and Xiuxiu remained standing where they were, quietly watching this scene.
The sunlight through the dome seemed even brighter. They knew that the more turbulent, magnificent era belonging to these young people was gradually opening, accompanying this ceremony of inheritance. And they, fortunate to be a link in this great transmission—this itself was an incomparable happiness and eternity.
