The combat held no surprises, and it's not as if the emperor-level BOSS of the Monster had not already called up his elite forces to attack Zhou Tian's territory. Even if the emperor-level BOSS had been in his own territory at the time, given Zhou Tian's current strength, the resistance of the emperor-level BOSS would have likely been ineffective.
Thus, given the strength of Zhou Tian and his Beastman army attacking an emperor-level power that lacked its BOSS, there naturally wouldn't be any unexpected outcomes.
As a result, Zhou Tian hardly had to take action a few times before, in the span of just a few days, an emperor-level force fell into his hands. However, just as Zhou Tian seized the territory and was about to leave, the emperor-level BOSS of that time unexpectedly returned.
