Jiang Yifan held the rough sketches of bolts and nuts Ye Xinyan had drawn for him and gradually furrowed his brows as he recalled what Shi Yin had said.
Watching the unexpected change in Jiang Yifan's expression, Ye Xinyan had no idea why he seemed displeased. Threaded fasteners were something that would be found in every corner a thousand years later, and she could not understand how such a vastly significant invention could be displeasing to Jiang Yifan. Yet, Ye Xinyan didn't ask further and simply waited for Jiang Yifan to speak up.
Of course, if Jiang Yifan chose not to speak up, she had no objections and was content with the quiet.
However, Jiang Yifan didn't grant her that wish and the words he spoke were quite overwhelming for her.
"When do you estimate Mr. Shi will be able to research and produce the lathe you mentioned?" Jiang Yifan asked, his tone rather strained.
Ye Xinyan gave Jiang Yifan a surprised look. Was there a need for such strong emotions over this matter?
