The Yan siblings returned to their home at Zuimo Court and found that, in addition to the young Tian Yu, Song Yi was there as well.
Hearing the reason for Song Yi's visit, Yan Feifan asked in surprise, "The infusion controller prototype is already designed and built? That was fast."
The smartly-dressed Song Yi said, "Three weeks isn't exactly a short amount of time."
"The product's functions aren't complex and are easy to implement. The outsourced design team spent most of their time on feature integration, cost control, and exterior design."
"Of course, this is just a prototype. The design team can still scrap it and start from scratch or continue making improvements based on our feedback."
After this brief explanation, Song Yi asked, "Where's Su Ye?"
"She's on the night shift at the hospital tonight."
Yan Feifan replied, then added an invitation, "Song Yi, you haven't had dinner yet, have you?"
"Let's eat first, and we can talk about the product afterward."
