Yes, if the two of them "crashed" away from the platform, they could only die together. However, if they were very close to the platform, one side would only need to use the other side's head as a springboard to jump onto the platform. Then, they could survive by triggering the 'collision' condition.
This was not difficult for a Rare-ranked creature, right?
Of course, if one knew the Wudang alacrity technique—Cloud Jumper—one could also step on the back of one's left foot with one's right foot and jump onto the platform to avoid being hit.
However, the bald middle-aged man no longer had this chance. In fact, he would have died if Wei Huo had not wanted to expose his strength.
If one was not strong enough or smart enough, how could one survive such a death threat?
