The Paragon of Pills, Emperor Gonflame, and Ji Ning all stared at that distant mountain of darkspace flamestone. This was one of the many marvels birthed from the primordial chaos in this universe!
"Darknorth." Emperor Gonflame suddenly said, "Six lifeblood weapons will take quite a bit of time. Even if I enter my estate and accelerate time, the smelting will still take tens of thousands of years. You'll have to wait."
Alchemy, artificing, seal-making, and other Daos all took enormous amounts of time. Major powers would generally carry out the process within estates that had temporal acceleration enchantments!
"Tens of thousands of years?" Ning laughed. "Then I'll just wait patiently for those six lifeblood weapons."
...
Tens of thousands of years. This could be said to be a long period of time, but it could also be said to be a short period of time.
