From the perspective of the outside world, Zhou Tian should have hurried to the original battlefield as soon as possible at that time.
The Divine King that Zhou Tian supported was much weaker compared to their enemies. If Zhou Tian hadn't appeared on the battlefield to share a large amount of pressure, it probably wouldn't have taken long for the enemies to capture him. If events reached that point, neither Zhou Tian nor the Divine King he supported would come out well.
Therefore, given the situation at that time, if Zhou Tian didn't want their camp to end up in defeat, he naturally had to think of ways to support the Divine King he supported as much as possible. Only if he could hold on a little longer under the enemy's attack would Zhou Tian have more time to grow.
