The reason he took out these two items was that even if someone else got hold of them, they would not notice anything unusual. The same went for the special materials inside the body armor. At most, they would just call it extravagant.
Mainly because, by conventional standards anywhere in the world, these two items were extremely expensive to produce. Equipping ordinary soldiers with them was completely unrealistic.
But in reality, some minerals were scarce here yet abundant in Great Qin, to the point where they could be considered ordinary minerals. There were also many unique plants.
Anyone who knew anything about materials science knew that plants could produce many special materials as well.
The most widely used example was ordinary rubber. That stuff counted as a kind of biomaterial.
However, their understanding of the Great Qin world still needed to be explored further. Minerals, on the other hand, were easy to find, and modern chemistry and other fields had already been studied extensively, so their properties could be analyzed with ease.
Thus, many products were still under constant development. In particular, if metallic elements that were extremely rare on Earth existed in large quantities in Great Qin, then rare earths might not be called rare earths in the future.
But even if they no longer counted as rare earths, the country would never export them in large quantities. Meanwhile, industrial raw materials like titanium ore were extremely abundant in Great Qin.
And that was only what had been detected within the areas currently controlled by the country. As the scope of exploration continued to expand, there would surely be many more surprises waiting for them.
It could be said that these resources had greatly reduced the difficulty of advancing domestic materials science, as well as the cost of many
