These Wooden Ox and Flowing Horses are just simple puppets.
Their structure is very basic, capable of only mechanical forward movement, backward movement, and turning.
Even the Little Tiger designed by Mo Hua is more complex than these, but for the purpose of transporting ore, they're sufficient.
Due to their simplicity, only the most basic Spiritual Pivot Formation is needed.
Unlike the Corpse King, there's no need to draw complex Sequential Formation Patterns, and build hundreds or thousands of Spirit Pivot tiers for layered control.
Therefore, even Young Master Yun, who was just beginning to learn the Spiritual Pivot Formation, could draw it.
And with Young Master Yun's help, the progress was much faster.
But after the drawing was completed, things weren't that simple.
These Spiritual Pivot Formations and Ox and Horse Puppets still had to be used in practice and adjusted accordingly.
