The moment the four entered the arena, Mo Sen and the others were already prepared to deal with the rocks overhead.
Once they officially entered the fourth trial, each of them was randomly teleported beneath a massive boulder, and the boulders that had originally floated in the air came crashing down.
The boulders fell so quickly that there was no time to think.
Either shatter the boulder head-on with one's still-formidable physical body, or be crushed into a meat pancake beneath it!

Yet Mu Qing actually condensed a surge of soul power and blasted it toward Mo Sen!
Mo Sen's scalp went numb. That soul attack was utterly terrifying. In his current state, suppressed by the fourth trial, he absolutely could not withstand it!
Ji Haimu was equally shocked.
