He Xingzhou was searching in the realm of microscopic technology and indeed found something.
"Two-dimensional carving technology."
"Two-dimensional carving is a technique to unfold the three-dimensional structure of microscopic particles into two dimensions, and then carve various structures."
This technology was a revelation to He Xingzhou. What is the hardest part of making microscopic weapons? It's that microscopic particles are simply too small!
An atom, with its surface area, volume, and mass, has only so little—how much can you proceed with that?
Mass and energy often determine the lethality of a weapon. King Tang's Atomic Warship can only shatter microscopic matter.
It can destroy a War Star because it uses a clever method by destroying key atoms, creating a chain reaction.
And this two-dimensional carving technology perfectly solves this issue.
To human eyes, microscopic particles are so small they're invisible.
