The carriage is being surrounded by bandits that outnumber the guards protecting it. Some of the guards have already fallen. Adrian immediately commanded the three soulbounds that he summoned to take care of the bandits.
The bandits are not that much different from Adrian's level which meant that he could deal with two at a time. Adrian decided to sit this fight since he wanted to test just how well does the buffs hold for the soulbounds.
The bandits did not expect attacks from monsters while they were attacking the carriage. They have yet to do what they came here for and that is to kill the noble inside the carriage. It seems that the noble is an important person that will be wed to a lord in an area.
The marriage of the two will forge an alliance that some of the other ruling class in the eastern continent do not like. The holy beasts might prevent people from attempting doing something bad in the open but that did not mean that they cannot use sneaky means.
