Ye Xinyan was only speaking offhand; Shi Yin was a senior craftsman who could instantly recognize the importance of Zhou Biyao in the Mechanical Workshop. How could she not know? During the production of the Chain Inversion Device, she merely provided an idea and the operating principle. Though she consulted with Wong Qiao about the details of various parts, when it came to specific tasks, she was still no match for Zhou Biyao.
So, the next morning, after breakfast, Ye Xinyan coaxed Qi Jiaer to go to school with sweet talk but still promised Zhou Biyao she would visit the workshop to watch the trial of the Chain Inversion Device.
Just after Chen Hour, Jiang Yifan arrived at the Qi family, initially paying respect to Madam Yin. After sitting for a short while, Ye Xinyan's maid came to invite them to the workshop to observe the Chain Inversion Device being used to lift weights.
