Time was the most silent sculptor.
It used no knife, no hammer. With only one tool—"repetition"—it could grind every rough stone blank into a precise gear.
Bloodborn civilization was being shaped by this sculptor, cut by cut.
The holographic projection before Ron had already been adjusted to its maximum scale.
In that hilly region he knew best, changes were happening at a dizzying speed.
"Surface → underground → return to the surface."
He wrote those three stages side by side in his notes, then drew an upward-curving arc to connect them.
Iron Tide metalworking technology was the fuse that ignited the outbreak.
After that primitive trade of ore for tools was established, the scale of exchange between the Bloodborn and the Iron Tide expanded rapidly.
What the Iron Tide provided was not merely finished tools, but also an extremely simple yet efficient template for metal smelting processes.
The Bloodborn light artisans soon discovered that combining smelting parameters with their own deep understanding of glowstone's properties could create new products far beyond their current technological level.
This was the background behind the birth of "Glowstone Concrete."
Glowstone powder was ground to the submicron level, mixed with metal in specific proportions, then poured into prefabricated molds.
The curing process required continuous light catalysis, which happened to be the Bloodborn's natural advantage.
The body-heat radiation emitted by the stellar fragment happened to fall within the optimal activation wavelength range for glowstone powder.
A Glowstone Concrete wall simultaneously served three roles: load-bearing structure, energy storage unit, and lighting source.
"Breakthroughs in materials science are often the prelude to a civilizational leap."
Ron wrote in his notes:
"When a race learns to reshape its habitat with new materials, they are no longer creatures passively adapting to nature, but a civilization beginning to actively transform the
