An idea struck Shen Bing. "Commander Gao, you're putting me in a difficult spot. That Invisibility Potion is made entirely by hand. As for output, I couldn't make even one little bottle like that in a month. And although it works well, it has a lot of restrictions on its use. Mass production wouldn't be particularly worthwhile."
Commander Gao snapped, "You think it's not worthwhile just because you say so? Do you think something only has military value if it's used in combat?"
Shen Bing said helplessly, "Fine, you're right about everything. I was planning to spend some more time seeing whether I could develop a stealth material with a similar effect. But since you think the potion is already valuable enough, I won't bother researching it any further."
Commander Gao's breath caught. A material? A material with a similar invisibility effect?
That was worth pursuing! How could he stop researching it?
In fact, after receiving the Invisibility Potion, Commander Gao had immediately rushed to Kyoto and tested it at a Military Research Institute. The results had been astonishing.
The military researchers' first reaction had been to use the principle behind its invisibility to develop a bionic invisibility material with the same effect. But their very first experiment ran into the same problem Shen Bing had encountered earlier, making further research impossible.
Settling for the next best thing, the researchers turned their attention back to the formulation, only to suffer another crushing blow. It was simply a mixture of various compounds, with no detectable abnormalities whatsoever.
In that respect, it was just like the Basic Spiritual Wisdom Potion and Animal Enhancement Serum Shen Bing had provided earlier. They knew exactly which substances made up the materials, yet they could not figure out how they worked. They could not even reproduce
