Moreover, although the possibility was slim, what would he do if a large number of Third Tier monsters suddenly appeared out of nowhere?
Since the Multiple Choice options referred to it as an accident, Zhang Yanhang felt it was quite reasonable to speculate as much because if it weren't for some unexpected event, it couldn't be called an 'accident'.
Even more so, this accident must be one that had a significant impact on his Crimson Iron Ant Nest clearing plan; otherwise, the options wouldn't have mentioned that he needed to modify the plan after entering the Crimson Iron Ant Nest.
After all, if it were a minor accident, how could it possibly require Zhang Yanhang to modify the Crimson Iron Ant Nest clearing plan? More importantly, if it really were a minor accident, Multiple Choice wouldn't even list it in the options unless it was important enough to be indispensable.
