Stepping back into the past:
Maleshaman gave you the best current advice for getting past such current blocks.
Buy some revive scrolls > run through the blockers > die > revive > eat food > run through crossing and keep running until you have successfully hid from the mass chasing you.
You are invincible when you revive, until the timer times out or until you use a skill or potion/scroll, cross a crossing.. ect.
revive > eat > and run
Yes there is countless topic about chainless blocks, and they will keep being created until devs include more possible crossings.
