Of the human race's only five remaining cities, they now encircled one another, four on the outside, with Han Yun City at the very center.
Aurora City was vast, but it could not possibly encompass every road leading to Han Yun City.
If the Ice Clan and the Ghoul Clan chose to bypass Aurora City and strike directly at Han Yun City and the other three cities, they could absolutely do it.
It was just that under normal circumstances, the Ice Clan and Ghoul Clan would not make such a choice.
Because if they did not uproot Aurora City and instead chose to drive straight in, the final result would very likely be getting pincered from front and back by Han Yun City and Aurora City.
But in all things, there was always that one chance. If the Ice Clan and Ghoul Clan refused to play by common sense, or chose to send a small force plunging into the human rear, and the human race failed to discover it, then they would be placed in an extremely passive position.
Thus, for the positions between Aurora City and Han Yun City that were not protected by city walls, Aurora City needed people to garrison them. If anything happened, they were to notify Aurora City at once.
Cliff Grinding Mountain was one such location.
Cliff Grinding Mountain was two thousand miles from Aurora City. To the Dao Fusion Realm, that distance was nothing.
Considering that Chen Fei had only broken through to the Dao Fusion Realm not long ago, and his realm might still be in the stage of stabilizing, they had chosen such a position for Chen Fei.
If anything happened, Chen Fei could choose to leave Cliff Grinding Mountain and simply report the situation back to Aurora City.
