The word Shukuchi (縮地), sometimes written Shukuchihō (縮地法) or Shukuchijutsu (縮地術), is a Japanese term for ancient techniques of rapid movement. It means “shrinking the earth” referring to how the technique reduces the spatial distance between two points.
The word first appears in Chinese, in the book Biographies of the Deities and Immortals of the Taoist philosopher Ge Hong (283-343) to describe the ability of Fei Changfang (費長房) a Taoist magician of the Han Dynasty.

Fei Changfang has a divine ability,
he can shrink the Earthly veins.
Be a thing thousand miles away,
it would appear right before his eyes.
And if he let the meridians go,
they would turn loose, the way they were.

Fei Changfang learned the art of Shukiki after a ten-day training period on Hugong Mountain. He faced various trials, being left alone with a pack of tigers and then enduring hanging upside down from a rope under a large rock. After successfully overcoming these challenges, he refused to eat a cake made of excrement and insects and returned to humanity. Only then did he realize that while he was on the mountain, the actual time elapsed on Earth had been over ten years.
