This was definitely a big discovery, maybe after spraying the entire ground of the house with saltwater, I would be able to find out where these footprints led, and perhaps through them, find that missing cloth doll.
After spraying four times, the saltwater in the cup was exhausted. Having no choice but to go back to the kitchen to make more, I saw that there were even more footprints on the ground. They extended towards the direction of the door. As for the final destination of these small footprints, I still did not know, because the area covered by the saltwater was still very limited.
After getting to the kitchen, I directly replaced the saltwater cup with a small basin. This way, I could carry more saltwater in one go—it was too much trouble to keep running back and forth with a cup. Actually, the basin wasn't that big, probably about ten times the volume of the cup. I filled it with water, added salt, and walked out of the kitchen holding the basin.
