If the two sides of a conflict turn against each other, it could result in the whole of the Great Ming realm being set ablaze. This wouldn't only lead to chaos, but also result in the death and injury of numerous powerful figures. The Taoist School and the imperial court of the Great Ming would also experience significant losses.
This is undoubtedly a situation where both sides would be damaged, a result that nobody wants to withstand.
Hence, there are times when compromise is necessary.
Just like when Pei Xuanjing and the others initially banded together to demand power from the Great Ming royal family, the royal family had the power to fight back. But they chose to compromise because they didn't want to end up in a mutually destructive situation.
Now, the tables have turned and Pei Xuanjing has taken the place of the former Great Ming royal family. Those in the Ji Fang Alliances are now reprising the role Pei Xuanjing and his group played before.
