In the inheritance of the Black Iron Dwarves, the status of Quenching Castle is second only to the Ancestor Temple.
After the Abyss Descent, the Black Iron Dwarves migrated multiple times to avoid the pollution of the Abyss, and many inheritances were lost.
The Ancestor Temple has become a holy place that the Black Iron Dwarves can never return to, appearing only in their dreams.
Similarly, before Lu Heng mentioned Quenching Castle, it was a legendary holy place for the Black Iron Dwarves, believed to no longer exist.
Now, Quenching Castle has reappeared, and the Black Iron Dwarf Kingdom has established contact with it.
This means that the Black Iron Dwarves have found the holy place of their dreams.
It's imaginable how excited the Black Iron Dwarves present were.
So much so that when Gulu spoke in a commanding tone, Dwarf King Sorreville Copper Furnace did not feel anything was amiss.
