Can it be used for infrared-guided missiles?\"\u003C\u002Fp>\n\u003Cp>It was no wonder he was so sensitive—the shadow left by infrared-guided missiles on China was too deep.\u003C\u002Fp>\n\u003Cp>The first combat application of infrared-guided air-to-air missiles involved China.\u003C\u002Fp>\n\u003Cp>The feeling of being technologically suppressed was too bitter; everyone in China’s military-industrial and technological sectors remembered it vividly.\u003C\u002Fp>\n\u003Cp>\"It cannot be used to manufacture infrared-guided missiles. It can be used to optimize them.\"\u003C\u002Fp>\n\u003Cp>\"The greatest technological gap between us and America lies in materials and manufacturing processes.\"\u003C\u002Fp>\n\u003Cp>\"I’ve communicated with colleagues at Shenhai Electronics, Shenyang Materials Institute, and Xi’an Engine Institute. The main reason past projects were never approved was...\"\u003C\u002Fp>\n\u003Cp>\"America’s AIM-98 uses lead sulfide infrared photosensitive elements. We lack the high-purity lead sulfide single-crystal growth process. If we use domestic lead sulfide detectors, sensitivity is at most 70% of theirs.\"\u003C\u002Fp>\n\u003Cp>\"Their detection range is 8 km; ours is theoretically only 5 km.\"\u003C\u002Fp>\n\u003Cp>\"The missile seeker also requires high-precision germanium lenses. We cannot mass-produce aspherical lenses with polish accuracy reaching one-tenth the wavelength—we can only rely on hand grinding, with a yield below 5%.\"\u003C\u002Fp>\n\u003Cp>\"Combined with backwardness in signal processing circuits, solid propellants, missile structure, and more, even if we spent time building one, it would be outdated and practically unusable.\"\u003C\u002Fp>\n\u003Cp>\"But now, with angular vector projection to predict impact points, even with our gaps, we can reach a usable level.\"\u003C\u002Fp>\n\u003Cp>\"So previously, even if we launched, we couldn’t hit them.

You may have little time to reunite with your family. Are you willing to participate?\"\u003C\u002Fp>\n\u003Cp>Hua Luogeng was no fool—he immediately guessed the reason.\u003C\u002Fp>\n\u003Cp>\"If the nation needs me, I will not hesitate.\"\u003C\u002Fp>\n\u003Cp>Xiangjiang, Modeng Terrace.\u003C\u002Fp>\n\u003Cp>\"Madam Meng, Professor Lin has arrived at the gate.\" The maid, Liu Jie, entered Meng Xiaodong’s room and whispered.\u003C\u002Fp>\n\u003Cp>Meng Xiaodong was a renowned Peking opera performer, known as the \"Winter Emperor,\" who had long since retired to Xiangjiang and ceased performing.\u003C\u002Fp>\n\u003Cp>Not performing did not mean she ignored current affairs; she was naturally curious about this figure who had stirred up Xiangjiang’s summer.\u003C\u002Fp>\n\u003Cp>From newspaper reports alone, he was young, handsome, and brilliant—praised by Xiangjiang media as a mathematical genius born once in centuries.\u003C\u002Fp>\n\u003Cp>What intrigued her more was why he had come to see her.\u003C\u002Fp>\n\u003Cp>Three years ago, Zhang Shizhao had urged her to return. In her view, her only remaining value lay in teaching—but Professor Lin was an American professor. Could he be trying to persuade her to go to America?\u003C\u002Fp>\n\u003Cp>Another possibility was that he was a fan of her operas, wanting to meet her in person.\u003C\u002Fp>\n\u003Cp>But that possibility, given his age, seemed laughably unlikely.\u003C\u002Fp>\n\u003Cp>Still, Meng Xiaodong had not refused his visit request; she even looked forward to learning his purpose.\u003C\u002Fp>\n\u003Cp>\"Professor Lin, your reputation is well deserved. Not only are you striking in appearance, but your entire demeanor embodies the classic scholar’s spirit,\" Meng Xiaodong complimented.\u003C\u002Fp>\n\u003Cp>\"Thank you, Miss Meng. I’ve come hoping you can help me record a short melody.\" Lin Ran pulled a sheet of sheet music from his suit pocket and handed it to her.\u003C\u002Fp>\n\u003Cp>This was not what she expected. Meng Xiaodong picked up the sheet music; besides the neat handwriting, the title caught her eye:\u003C\u002Fp>\n\u003Cp>\"Bishangguan?\"\u003C\u002Fp>\n\u003Cp>After reading it, she tried singing a short passage:\u003C\u002Fp>\n\u003Cp>\"...\"\u003C\u002Fp>\n\u003Cp>\"This journey, shamed, I drink at banquets of joy\"\u003C\u002Fp>\n\u003Cp>\"How can my youthful face remain unchanged?\"\u003C\u002Fp>\n\u003Cp>\"The murals once gleamed in splendor\"\u003C\u002Fp>\n\u003Cp>\"Yet I awake to watch from the wall...\"\u003C\u002Fp>\n\u003Cp>\"...\"\u003C\u002Fp>\n\u003Cp>Coming to Xiangjiang meant one unavoidable thing: giving interviews. More precisely, Lin Ran needed interviews—and this song, \"Bishangguan,\" was carefully chosen for that purpose.\u003C\u002Fp>\n\u003Cp>You arrive in Xiangjiang, and across the strait, China unveils a world-class short-range missile. Maybe it means nothing now, but once Lin Ran stirs up the American aerospace world, some departments and individuals will inevitably dig him up and make trouble.\u003C\u002Fp>\n\u003Cp>A single song, \"Bishangguan,\" is useless. What’s truly needed is to partner with General Electric and secure a NASA contract, proving his indispensability, with the Morgan family and the Rockefeller family behind Professor Hawkeheimer standing guard for him.\u003C\u002Fp>\n\u003Cp>But even if others protect him, they need a public justification—“Bishangguan” is the song he prepared to make his stance clear.\u003C\u002Fp>\n\u003Cp>The other song, given to China, is \"My Motherland and I.\"\u003C\u002Fp>\n\u003Cp>After singing, Meng Xiaodong clapped repeatedly, the applause softly echoing through the parlor:\u003C\u002Fp>\n\u003Cp>\"A fine song, fine melody, fine tone, fine metaphor—but Professor Lin, you’ve come to the wrong person. I’m a kunsheng, not a dan role.\"\u003C\u002Fp>",1156,"2026-06-19T21:37:46.551Z",1,"Qwen3-Next 80B","05c38ef5f1b337917699f842b44a757cba0c1344f74e710b00dd14d9158357ce","technology-invades-the-modern-world-chapter-38","technology-invades-the-modern-world-chapter-36",162,"https:\u002F\u002Fnovelzhen.com\u002Fimages\u002Fcovers\u002Ftechnology-invades-the-modern-world-cover.jpg"]
