After washing her hands clean, Su Yunjin found a knife and used it to slice the blood in the wooden basin into uniformly sized chunks for later use.
She scrubbed the pot, then added a large pot of water to it, and heated it on high until it boiled; she proceeded to pour the congealed pig blood into the hot water to cook.
After cooking for a while, Su Yunjin used a pair of chopsticks to pinch one and saw that the color inside the blood chunk was consistent with the outside, then she quickly fished all the pig blood out of the pot and soaked it in the cool water she had prepared.
Pig blood treated this way is not only easy to keep but also doesn't break apart easily when cooked at any time.
"Yunjin!" Gu Ya's voice came from outside the kitchen, and Su Yunjin, who was scooping the pig blood from the pot, looked back instinctively, only to see Gu Ya returning from hunting in the mountains.
