On reaching home, the archer hid his precious pill under a rafter, lest anyone should steal it, and then began the preparatory course in immortality.

At this time there appeared in the south a strange man named Tso Ch’ih, ‘Chisel-tooth. ’ He had round eyes and a long projecting tooth. He was a well-known criminal. Yao ordered Shên I and his small band of brave followers to deal with this new enemy. This extraordinary man lived in a cave, and when Shên I and his men arrived he emerged brandishing a padlock.

Shên I broke his long tooth by shooting an arrow at it, and Tso Ch’ih fled, but was struck in the back and laid low by another arrow from Shên I. The victor took the broken tooth with him as a trophy.
