Bai Youwei made a quick decision and moved the incense burner and all her props into the dollhouse.
After all, the dollhouse is essentially a prop!
If you're going to smoke one thing, you might as well smoke a bunch. The more, the better!
Bai Youwei calculated that from last night to this morning, the burning incense was effective for about 8 hours. If every eight hours of fumigation gave the mud one extra use, then after 56 hours, the mud would return to its initial state of being usable nine times!
Four pieces of mud together—36 uses! To put it bluntly, it's like saving 36 lives!
Bai Youwei decided to stay in the dollhouse, going nowhere, checking the condition of her props every hour, intent only on waiting for the final result.
Yan Qingwen came to see her during this, along with Zhu Shu and Su Man, presumably to thank Bai Youwei. But since she was inside the dollhouse, they didn't find her.
Bai Youwei stayed from morning to afternoon, for a total of 8 hours.
