Apart from this, there were also small scales for weighing medicinal ingredients. Su Xinyi had someone help her separate the papers which she then piled up three or four sheets at a time on the ground. She used the scales to weigh out different amounts of materials like saltpetre, charcoal, and sulphur, then mixed them together and put them on the papers.
After Su Xinyi had measured out one portion, she looked at Qin Guansheng and the others and said, "I'll make one for you to see. It'll be faster if we all work together. Mix the things on the paper evenly, then wrap them into a cylindrical shape. Add a fuse and tie it tightly. If it falls apart midway when launched, all our efforts will be wasted."
Su Xinyi worked quickly, in a short while, she had made one. It didn't look very elegant, but Qin Guansheng had seen the rockets used by the Divine Machines Camp, and this looked somewhat similar.
