The two Barbarians who were on the lookout were of similar strength to the one that Thirteen had just killed.
If he had to make a guess they were in their late teens, and would probably grow stronger once they get older.
But, they wouldn't have that opportunity.
The only people that Thirteen wouldn't blatantly kill were very young children because even if he was cold blooded, he still had his bottom line.
Also, the situation didn't allow him to show mercy.
He didn't really care about the other teenagers, but he wouldn't allow Cristopher and Harry to be sold as slaves.
His goal was still to go to the Barbarian Kingdom, but he would go there on his own terms, and not tied up as a slave.
After nearly half an hour had passed, the two Barbarians thought that their friend was taking too long in handling his business.
"You tell him to hurry up," one of the Barbarians said, making the latter frown.
