Pluck a Feather and Give It to Me

When the Giant Tsunami Turtle heard that Yun Chujiu had found a clue, its eyes showed surprise. It was afraid that it would disturb Yun Chujiu's thoughts, so it obediently floated on the surface of the water and did not move.

Yun Chujiu returned to her wooden raft and sorted out some of the thoughts that she had just thought of. Then, she recalled some of the principles that she had seen in her previous life.

The essence of biological movement was circular movement. If there was no target, the instinctive movement of any living creature would be circular. But why could living creatures keep moving in a straight line? For example, why did humans walk in a straight line?

Because we use our eyes to constantly correct the direction in which we moved, our brain made corrections in our positioning so we walk in a straight line.
