Drawing lots?
Perhaps this was a good method.
Everyone would draw lots based on luck, whatever they drew was theirs, no regrets allowed.
"What do you say? Do you all agree?" King Zhenbei, Li He, said cheerfully, "If everyone agrees, then let's start drawing lots."
"Alright, let's draw lots." Elder Feng of the Feng Family nodded.
"I agree as well," said the Great Elder of the Li Family, Li Wentian.
"We agree too," others also nodded one after another.
"Very well." King Zhenbei, Li He, had someone fetch paper and pen and wrote down various parts of the dragon corpse in front of everyone, such as dragon horn, dragon whisker, dragon claw, and so on. After writing, he folded the papers and placed them in a sealed box, "Everyone has seen, right? I didn't cheat, soon everyone will draw lots based on luck, whatever you draw is what you get, absolutely no backing out." As he said this, King Zhenbei, Li He, shook the box a few times, "Everyone line up, one by one."
