I Robbed the Cave and It Turned into a Cave

Three hundred and twenty-seven years ago, I broke through the restrictions and rushed into an ancient cave to steal treasure. I grabbed it. Then, I became this cave. Now I am a mountain that can eat people. The monks came one after another to break in and seize the treasure, but all I could do was lie down at their feet and kindly advise: I advise you to run away quickly.
