High-energy physics is a research field with vast differences in direction but high levels of integration.
A high-energy physicist might have substantial achievements in laser physics, quantum physics, nuclear physics, and micro science, with research tools and environments that are highly versatile and rely on each other's research to make progress.
So Zhao Xiaowen understood Lu Qiu's implication right away—he was hinting at Electromagnetic Control Technology.
Indeed, he had first-hand experience. Although the technical materials for the laser smelting satellite contained related technologies, the technologies used on "Blazing Sun," "Chi Ren," and the "C172-A" metallic hydrogen battery also heavily employed micro strong electromagnetic force control.
