Lord Wang Xian thought of the machinery that was seven or eight squares in size and couldn't help but ask further, "Your Majesty, this humble official will immediately summon my subordinates and Ministry of Works officials to discuss. However, we still have many questions about that device called a lathe, and I wonder if there is someone at His Highness Prince Yu's residence who could resolve our doubts?"
The emperor looked towards Jinrong, who wasn't inclined to keep secrets and replied, "Among the people who delivered letters and goods to the capital, there are two who have worked in the Mechanical Workshop. Lord Wang, if you have any questions, just send someone to Prince Yu's residence to inquire. I will let Uncle Wan know when I return."
