You spend a short period to search the area around your sect for any kind of volcano, but are answered by a complete lack of any such geographical feature anywhere near enough for your plan to use it to train your disciples. Without it you turn to ordering the new disciples into the same training regime that your other disciples have endured while the the Steelhearts, and Copperfeet are ordered to expand the sect's cavern through punching it repeatedly.
Your disciples spend nearly two months expanding the sect through punching the cavern walls leading to all of the copperfeet crippling themselves though the Steelhearts prove to be made of strudier materials, but sadly that proves of little use as near the end of the second month you hear the cavern begin to rumble. Before you can react the cavern starts to collapse, and you start to flee only for a chunk of stone ten feet in diameter to come crashing down upon you, though it does no damage it stuns you just long enough for you to quickly become buried underneath the rubble. You spend what you can only assume to be months trapped underneath a mountain worth of stone, undamaged but slowly beginning to suffer the effects of starvation, dehydration, and oxygen deprivation.
Precisely three weeks after the cavern collapse Zhao Li dies, and the Ironstrider Sect was destroyed in the cavern collapse never to rise to prominence ...

Yeah, wasn't expecting that .... You guys rolled very poorly which usually wouldn't have been a problem except you were having people expand a cavern by punching the rocks until they shatter, and your focus was defense not senses so you missed the signs of instability growing. Even without that though you did cause your Copperfeet to be crippled by sending them to punch walls, and almost all of the Entry Disciples had died under your training.
You guys were nearly invincible, your students were far from it especially considering you seemed to be assuming they'd be as sturdy as you are when you were a practitioner of a technique meant to make you invincible, and they weren't. :v
