Liu Di had a vague idea of what was going on.

He let out a soft sigh.

Magic Child's voice came through. "The components in this mechanical core only have minor issues. The biggest problem is the core power source!"

"At the center of the core is a massive strip of spring steel, shaped like a gyroscope and coiled layer upon layer. If my analysis is correct, this was the primary power source of the ancient Mohist Mechanical City. Nowadays, we call it a mainspring!"

Liu Di nodded slightly.

A thousand years ago, there was no combustion energy, much less electrical energy. Using a mainspring to drive machinery was only natural!

"This machine can't be wound up now!"

Magic Child said, "The reason is that the mainspring has a locking mechanism. It's extremely intricate, and no one can open it!"

Liu Di nodded.

With several leaps, he climbed to the top of the mechanical core. There sat a delicate wooden box no larger than a suitcase.

The wooden box appeared casually placed, but countless wooden structures extended from beneath and along its sides, connecting to the entire mechanical core.

Liu Di slowly opened the box's lid.

Its intricacy was even more astonishing.

It was entirely constructed of wood. A rough estimate put the number of components at over ten thousand. Some of the tiny bearings were nearly as fine as strands of hair.

Liu Di nodded in admiration. "Mozi truly deserved to be called an extraordinary man. This kind of craftsmanship is terrifying to behold!"

At that moment.

Striving Youth also huffed and puffed his way up. The instant he saw the wooden box, he grimaced. "Is
