"Ye Jiu, come out for a moment, I have something to tell you," Ye Jiu said.
Ye Gaosheng hurriedly got up and walked clumsily to Ye Jiu, asking to please her, "Little sister, what do you need from your fourth brother?"
"Fourth brother, do you know where I can buy caustic soda?" Ye Jiu asked.
This was another very important ingredient for making soap; only caustic soda could oxidize the lard successfully to create soap. Without it, not to mention washing hands or faces, it would only be greasier.
Ye Jiu had just finished speaking when Ye Gaosheng jumped in shock, "Little sister, why do you ask about this? Caustic soda is dangerous, you can't just play with it."
"Don't worry, I won't play around, I need it for a serious matter," Ye Jiu responded.
"What matter?" Ye Gaosheng asked.
"It's about whether our family will live a good life or continue to struggle," Ye Jiu teased, saying, "Just tell me where to buy it."
