Butchering cattle and deer is a skilled craft, so Li Jinyu, Li Yucheng, Jiang Jianguo, and the others naturally came over to help and offer guidance.
When Li Xiang captured these wagyu cattle and sika deer, he had tossed them, still alive, directly into his system storage, where they died instantly. Now that he was taking them out, they were in much the same state as the moment of their death. This saved him the step of having to slaughter them, and their blood was still warm, so it wasn't too late to drain it.
Furthermore, Li Xiang's "kill" had been so swift that the animals perished before they could even react. It could be said they experienced very little fear before death, so the quality of the meat was exceptionally well-preserved.
