The reason why bosses occupy such a high position is not only because of the authority they possess to completely control the lesser monsters, but the main reason is their strength that completely suppresses these lesser monsters. Even a non-combative boss like Zhou Tian is still the most powerful existence in his race, and the gap in strength between other combative bosses and ordinary monsters is obvious.
Now, after the emergence of a team composed entirely of bosses like Zhou Tian, not to mention anything else, just based on combat power alone, their team has reached a considerably high standard. Adding the individual abilities they each possess, it's possible that Zhou Tian and his team might be able to fight against the Blood Moon Lord's direct armed squad.
Given the strength of Zhou Tian's team, when they launched an attack towards the entrance of the Skeleton Cave, the defense line formed by the undead monsters naturally couldn't play much of a role.
