The so-called sky was the edge of the space. It did not have weight, so its fragments were naturally lighter than the lightest leaf. The fragment fell gently towards the grassland, sometimes in the east, and sometimes appearing in the west hundreds of li away. It was impossible to estimate its trajectory at all.
After an unknown amount of time, under the attention of countless terrified gazes of despair, the fragment of the sky finally landed. It may have been on purpose, or it may have been accidental, but it landed perfectly on the mountainous Monster Bull. Immediately, the fragment transformed into extremely dazzling white flames, which gave off an endless amount of light and heat. The Monster Bull gave out a moo of grief and indignation, and disappeared into the white flames. Nothing remained of it, not even ash or smoke.
