Zhou Wulang had brought a large cauldron, originally intended for boiling water to bathe at home.
The other one for boiling the broth was smaller.
Zhou Wulang started a fire, knowing that the bones would need to stew for quite some time to release their flavor. But it was still early, and there was plenty of time before the meal, so he wasn't in a hurry.
So as soon as the fire was lit, he let Sixth watch it while he went across to gather some firewood.
Boiling broth consumes a lot of wood, and if they found more than needed, they could keep some for the next day or take it back home—too much was never a concern.
Manbao was curious about everything and ended up following Zhou Wulang into the woods because Keke urged her to. She dug up quite a few unfamiliar plants and tossed them to Keke, not caring whether the system had already recorded them or not.
The water boiled, and the bones tumbled around inside, slowly leaching out their rich oils.
