Han Fei had gained a lot from this trip to the Land of King Death.
Not to mention that he had obtained enough keys to the Monarch Palace, the hunting of a large group of Half-King from the Soul Sealing World had greatly increased Han Fei's soul power.
Of course, his biggest gain was finding Xia Xiaochan.
Therefore, although Han Fei didn't care about these peak-level Venerables, he didn't know how long it would take for Nian'er to make a breakthrough. Since he had nothing to do, he might as well do some hunting…
If Nian'er broke through to the peak-level Explorer, Han Fei estimated that the remaining twenty days might not be enough for her to make a breakthrough.
Of course, that was Han Fei's idea. The big demons of the Hundred Demons Clan certainly thought differently.
