Two horse-drawn carriages entered Chen Ku's grand courtyard, each loaded with small iron buckets.
Within the iron buckets was a type of lustrous mineral that resembled coal chunks, with faint patterns on them that, under the sunlight, emitted a cold light.
This was the Iron Essence.
It was a material even harder than pig iron, a type of rock-forming mineral, and the unequivocal choice for forging top-grade sharp weapons. Any weapon infused with a hundred jin of Iron Essence could have its hardness increased several times. Like crow sink sand, the Iron Essence was a mineral with extremely high density and mass; hence, 20,000 jin of Iron Essence were delivered by the Firewood Iron Shop using only two carriages.
However, Chen Ku's attention wasn't on the Iron Essence but on the horses pulling the carts. With 20,000 jin of Iron Essence split between two carriages, each carried 10,000 jin. What kind of horses are these?
