Why was 21 minutes and 57 seconds such a special time?
Because...
Qin Feng clearly remembered that the first time he extended the challenge, he had added 69 seconds, and the second time, he had added 48 seconds. Together, that made 1 minute and 57 seconds!
In other words...
After he had Gray Chicken touch the pink orb to extend the challenge, the Barrier-Breaking Blade's spawn time had also been pushed back accordingly.
This hidden rule might seem useless, but there's a lot I can deduce from it...
The Barrier-Breaking Blades were used to destroy Illusory Dream God Afterimages.
On the surface, more Barrier-Breaking Blades seemed to mean nothing more than more chances for trial and error.
But Qin Feng knew perfectly well...
The Illusory Dream God would never allow anyone to clear such an important challenge through luck!
Although the odds of killing the correct target by randomly destroying Illusory Dream God Afterimages with Barrier-Breaking Blades were extremely slim, there were over forty million challengers on the 20th Floor of Illusory Dream Well!
Even if everyone only used a few Barrier-Breaking Blades at random to try their luck, someone would eventually clear it through luck alone.
Was that what the Illusory Dream God wanted to see?
Absolutely not!
In other words, if I use Barrier-Breaking Blades to randomly kill these Illusory Dream God Afterimages, the chance of destroying the correct target is absolutely zero!
Put another way...
The real target isn't among any of the Illusory Dream God Afterimages here!
The Illusory Dream God Afterimage I need to destroy isn't here. At least, it isn't here yet...
This deduction gave Qin Feng an entirely new line of thought.
If the target was not here yet, then some condition had to be triggered to bring the real target into this
