Unceremoniously speaking, despite the Sheepman Tribe currently being stronger than the Dragonman Tribe by just a bit. However, because the Sheepman Tribe has dispersed its military power into several streams, their combat power aligned specifically against the Dragonman Tribe on that defense line is absolutely incapable of holding against the Dragonman Army's attack.
Therefore, if Zhou Tian were not to intervene or mobilize reinforcements, the breaking of that defense line by the Dragonman Tribe is merely a matter of time.
Of course, since Zhou Tian had already arrived at the defense line, he must consequently take some action.
Adapting to his initial strategy, upon reaching the Dragonman defense line, Zhou Tian didn't hesitate and led the elite small monsters by his side, to directly attacked the front-line command center of the enemy at that moment.
