Controllable nuclear fusion (codenamed "Prometheus"): It has been initially commercialized on a global scale and is operated under the leadership of the "Global Energy Alliance" (GEA). It solved the energy crisis, but also became a new center of power and geopolitical focus. The protagonist Lin Ran is one of the core contributors to this technology.
Optical invisibility (codenamed "Charon Cloak"): a revolutionary technology based on quantum materials and precise energy field control. It is not completely invisible, but can distort light almost perfectly, allowing the wearer to visually blend into the environment (similar to a chameleon, but far more effective). It also has strong interference capabilities against conventional detection methods (radar, infrared, etc.). Its core energy requirements are extremely high, and only "Prometheus"-level energy can drive it stably.
"Light core" paradox: The two technologies are interdependent and threaten each other. Fusion provides energy to drive stealth, but stealth technology may be used to destroy fusion facilities or steal their core secrets.
