After Huang Hanying suddenly glimpsed the secret of immortality in a puppet's body, she made extensive preparations, including but not limited to collecting various precious and rare materials to craft high-end puppets.
This was why she diligently ran her shop, earning money to support Huang Niu'Er, yet couldn't accumulate much wealth, so she had to budget her earnings from Spirit Stones carefully.
Her plan was meticulous. Considering that a fusion of soul and puppet might lead to memory blanks, she deliberately revealed some information about immortality to Huang Niu'Er, trying to encourage him to focus and run the small shop's business early.
This way, when her time was up, and she voluntarily abandoned her flesh to merge with a puppet body, he could manage it on his own while taking care of the puppet body that was as blank as a sheet of paper, like herself.
