After following Ning Tian into the private room, everyone was immediately drawn to the enormous, smooth wall before them.
Through the Mind-Soul Research Institute's research and development, the Heaven Dou Empire already had similar projection soul tools, but Huo Yuhao had created those using Light Magic as the foundation and soul tool core arrays as the medium.
So the light-guiding screen itself was not what caught their interest. What caught their attention was the attendant's statement that the screen's core energy source was an ore.
Powering soul tools with ore meant that ordinary people would also be able to use soul tools in the future.
Seeing Huo Yuhao's keen interest, Ning Tian immediately took out her gold card. "I'll buy this screen."
Huo Yuhao could not help laughing. "No need."
He had already used Spiritual Detection together with Tian Meng to examine the screen's internal structure closely.
"I just examined it with Spiritual Detection. The core of this light-guiding screen is an ore called bright sun soul stone. The energy it gives off is very gentle and weak, making it perfect for a screen, but unsuitable for attacks."
"The principle is simple. The difficult parts are the inspiration and how to turn that inspiration into reality."
"We can develop some ice-attribute ores from the Northern Territory. Using the same method, we could then make cold storage boxes for preserving food, or heat-relief machines with some kind of switch that controls whether they release cold air in summer."
Drawing three inferences from a single example, Huo Yuhao's words immediately gave everyone a great deal of inspiration.
They shared their ideas through Heartstring Resonance.
Some suggested using fire-attribute ores to design heating equipment, while others suggested using this screen as a reference to design an image-capturing device that would let people freeze
