Since they didn't want to waste time fighting with the zombie, the soldiers opened fire and shot at the zombie that was standing at the end of the corridor. One two people aimed at its head and the others focused on other areas, probably to confuse it.
Within a few seconds, the zombie was lying on the floor, dead. They were now more cautious and scanned to remaining floors that were above water before proceeding.
It seemed that the zombie earlier had feasted on the rest to get so strong. There were skeletons in various rooms, which meant that there had been other people or zombies in the building but had been eaten.
In fact, the group had planned to test how to use their cultivation in a fight and such a powerful zombie would have been a good whetstone. However, after coming across Mu Nan, they had to hurry back and go home earlier.
