After all matters were settled, Lin Yi returned to the headquarters to rest. Perhaps due to days of relentless work without proper sleep, combined with staying up all night before, she fell into a deep, dreamless sleep, unaware of the passage of time, waking only the next morning.
As soon as she got up, Lin Yi received news: the pulley blocks commissioned from the craftsmen the day before were already finished, neatly arranged on the drill ground for her inspection. After checking and confirming they were fine, she immediately sent someone to invite Tian Guihong and Song Lin.
The drill ground had several stone-built platforms. Lin Yi had two of them placed together. By the time Tian Guihong and Song Lin arrived, the platforms were already joined. Pointing to the devices on the platform, Lin Yi said, "These are pulley blocks. You can pick them up and take a look."
Tian Guihong and Song Lin each took a set and examined them closely. Tian Guihong stroked the wooden wheel and remarked, "So this is the pulley block you mentioned, Madam. The detailed regulations said it could save manpower, but I couldn't imagine how it worked. Even now, holding it in hand, I still can't grasp the principle."
