He pointed with his hand, and the wooden kite on the ground started flapping its wings, circling low in the air continuously.
This was an answer to Li Nuo's earlier question.
The Mohists possessed the power to control mechanisms, a skill only Mohist disciples possessed.
In the Martial Path's fourth realm, although one could also control objects through the air, it was not as effortlessly as the Mohists.
As for Li Nuo, with the First Realm strength of Legalism and the Imprisonment Skill, he could make objects switch from motion to stillness, but he could not bring lifeless objects to life.
He glanced at the broken wooden gear in Li Yun's hand, thought for a moment, and said, "You might try changing the number of teeth on these two wooden gears, perhaps then they wouldn't break so easily."
Li Yun blinked in surprise and asked, "What?"
Li Nuo did not understand Mechanical Techniques, but he happened to know a bit of mathematics.
