Zhang Caixin's breakthrough this time took a full seven days from the start until she successfully broke through.
In fact, this is considered fast. When Feng Jun arrived in the evening, he deduced that she would use less than eight days to break through, but unexpectedly, she succeeded in breaking through on the seventh day.
She started breaking through at midnight, and Feng Jun guarded for three days before perceiving her difficult progress through the first threshold.
Counting the initial preparation of over two days, this speed is slower than her previous advancements, but this is the norm for advancing to the Outcast Realm. If not for Chaoyang's slightly purer spiritual energy, her speed would have been even slower—even if she has a Pure Water Constitution.
Of course, if Feng Jun hadn't extracted the Red Pill so early, but used it now, the time would certainly have been shortened.
