"Chief, yesterday the Great Chief brought the original book, and we finally got a clear look!"
"What we have here is a double helix spring; however, the material of this spring is really hard to simulate. We don't have a way to make the spring as delicate, since this also involves the issue of remaking the spring machine."
The craftsman rambled on with technical jargon, but Li Wenli only heard one key point.
Great Chief, the original book?
Oh-ho?
Has the affair of His Majesty appeared?
As he was pondering the issue, the craftsman took out an ancient scroll from a drawer.
Li Wenli suppressed the excitement in his heart and calmly took the ancient scroll with trembling hands.
He looked it over seriously, only to see that the scroll's material was so ancient, its edges were frayed, a testament to the long years it had endured.
The yellowed scroll was also filled with numerous tiny annotations.
It seemed this was indeed the affair of His Majesty they had been searching for.
