Han Fei did find a nest for the Stone Spirit Turtle in a cave of coral. He had planned to fool the Stone Spirit Turtle into going to the Fire Cloud Cave. After all, that place was much remote, and nobody would disturb the turtle in the next thousand years.
However, the Stone Spirit Turtle stopped swimming and descended the moment it heard that the place was thousands of kilometers away. In the end, Han Fei finally managed to lead the turtle to the coral reefs.
In the cave, Han Fei asked, "Mr. Turtle, do you really not want to reconsider? It's only ten thousand kilometers away. It won't be good if you're caught and end up as a contractual spiritual beast when you rest in here."
The Stone Spirit Turtle, however, simply crouched and attracted the coral, stones, and seaweeds nearby to itself. Very soon, the turtle turned into a huge coral reef.
The Stone Spirit Turtle said, "Human being, you can go now! I have to sleep."
