Facing the confluence of two large armies, the enemy could gather more troops and form a force far surpassing the Qing Immortal Sect at one battlefield, aiming for a direct breakthrough.
The Qing Immortal Sect faced this force without any possibility of resistance.
And without the ability to hinder them, the outcome of this great war was also directly determined.
Therefore, this situation absolutely could not occur.
The Tianmen River area could not suffer any loss.
Zhang Xiuzhu had to block Taiping Dao and prevent them from converging with the Jiuzhou Immortal Gate.
For this, even if the entire central defense line was lost, it was a sacrifice worth making.
If the three nations of the central region were lost, at the rear, Qing Immortal Sect still had more territories and could form more defensive lines at any time.
But if Tianmen River was lost, then all was lost.
Which mattered more was very clear in Zhang Xiuzhu's heart.
