Their goal was to destroy the World Tree, not to fall out with Black Star. Although they were not willing to let Han Xiao subdue the World Tree, there was nothing they could do.
Marbruce and the others could only suppress the fear in their hearts and wait for a targeted plan to be discussed in the future. In any case, there was nothing they could do now. They could not really start the second round of the war with Black Star… Who wins and who loses was secondary. There was a third party who might still be eyeing them from the dark.
