Because the Ancestral Gods of Mankind launched a direct assault on their rearguard, the three tribes were forced to cease hostilities. The Demon and Ghost tribes, witnessing the Human Clan's growing power, had no choice but to join forces, temporarily merging into one tribe. Even the Ancestral Gods of these two tribes began to cohabit.
It wasn't that they had developed a fondness for each other, but rather they feared a surprise attack from the Human Clan that could lead to their swift annihilation if they remained divided. Two against one, with good coordination, could quickly defeat them, but three against two was a different matter. This led them to band together for warmth and survival.
It was precisely because of the decisive actions of these two tribes that the Human Clan subsequently shifted all its offensive strategies to conservative ones, entering a period of recuperation and mending the world's wounds.
