What skin did the Yellow Emperor use to make drums?

According to Shan Hai Jing and Huang Da Jing, there is a Liubo Mountain in the East China Sea, which is 7,000 miles into the sea. There is a wild animal on it, which looks like a cow. It is pale and has no horns. When you step into and out of the water, there will be a storm. Its light is like the sun and the moon, and its sound is like thunder. Its name is Kui. The Yellow Emperor got it, taking its skin as a drum and Lei Shou's bone as a branch, and it was heard to dominate the world within 500 miles.

Legend has it that there is a "Liupo Mountain" in the East China Sea of China, and Wei Xiao lives in Shan Ye. Kui's body and head are like cows, but she has no horns, only one leg, and she is black and blue. It is said that Wei Xiao emits the light of the sun and the moon and thunderous cries. As long as it goes in and out of the water, it will definitely cause storms. In the war between the Yellow Emperor and Chiyou, the Yellow Emperor captured Chiyou, made snare drum out of his skin, and made drumsticks out of his bones. As a result, the sound of playing this drum can spread all over Fiona Fang for 500 miles, which greatly improved the morale of the Yellow Emperor's army and made Chiyou's army terrible.

Wei Xiao was born with heaven and earth. There are only three or more drums in the world. The first and second drums were killed by Qin Shihuang, but Qin Shihuang did not have the achievements of the Yellow Emperor, so this drum made of Wei Xiao skin is not so magical.
