It was just as Calina mentioned. Their group quickly encountered the enemy group. Not only that, but it was the same size as their own. However, they had no intention to win or lose, just dragging it out as long as possible. With Rean and Roan around, the losses were reduced to a minimum. After all, Rean and Roan could use the Instant Recover Skill. It's just that Roan wasn't as good at it as Rean, so they separated their jobs accordingly. Rean focused on the most grievous injuries, while Roan took care of the rest.
Their enemy group didn't take too long to notice that Roan's group was holding them back. Naturally, they tried to increase their attack power, but it wasn't of much use. Eventually, their leader decided to retreat since they were entering too deep into the Jialin Army's territory.
