Many on Ling Tian's side had broken through to the Quasi-Saint Ninth Order, giving their overall strength a qualitative leap. By taking them by surprise, they could inflict casualties on Chi Xue and the others. For example, Feng Lingzi could suddenly teleport into their ranks. Chi Xue's side couldn't intercept everyone in that situation, so inflicting some casualties wouldn't be difficult. If they were lucky, they might even kill God Devouring Bodies like Shi Lin.
Once Chi Xue's side suffered casualties, especially if a God Devouring Body fell, they would surely choose to give up and wait until Po Tian, Chi Xue, and the others broke through to the Quasi-Saint Ninth Order before making a move. If that happened, Ling Tian and the others would only have to face the Outer Realm Demon Race cultivators, which would put them under very little pressure. Ling Tian and the others had already estimated that, against the Outer Realm Demon Race cultivators alone, they could probably fight their way to the central region of the northern part of the God Realm before suffering heavy casualties. Once their losses became severe, they would choose to give up outright.
If the Outer Realm Demon Race cultivators gave up, then Ling Tian and the others would have nothing left to worry about. After this, even more people around Ling Tian would break through to the Quasi-Saint Ninth Order. It wouldn't be impossible for there to be dozens, or even a hundred. That would be an exceptionally powerful force; even against the combined forces of the Outer Realm Demon Race cultivators and Chi Xue's side, they could easily hold their own and inflict heavy casualties.
Even if Chi Xue's people kept attacking after suffering some losses, so what? As long as there weren't any Ninth-Order God Devouring
