Introduction to "Resonance Killing":
International student Zheng Haoran received the encrypted last words of a "resonance weapon attack" from his mentor before he lost contact with the Malaysian Airlines, thus uncovering a shocking transnational conspiracy to hunt down top scientists. He returned home carrying a USB flash drive for studying sonic weapons left behind by his mentor, but encountered a crisis of trust because of the advanced evidence. Only national security officer Yu Kangcheng was willing to fight alongside him. When a passenger plane carrying the Dragon Kingdom's chief aerodynamics expert was attacked by the same means and one of its engines mysteriously caught fire, Zheng Haoran used USB flash drive technology to achieve a thrilling intervention and finally completely awakened the country's power. The Dragon Kingdom launched the "Zhongkui Project", gathering top experts to reversely analyze the principles of weapons, and the intelligence network simultaneously locked on the United States' "Oracle" base - the truth emerged: this was a precise extermination implemented using sonic resonance technology, intended to maintain technological hegemony. The first volume ends with the fire ignited by scientists with their lives, and the horn of silent war has just sounded.
