As it was not being beaten up by other monsters at the moment, the Forest Drake seemingly closed it eyes, gathering its energy to made an attempt to escape.
Something Alros could predict. After all, from what he manage to gather, the guardians are all loyal to the Spirit, and would do anything she ordered.
It's likely, from how all guardians seemingly monsters made out of trees, that they are creatures created by the Spirit Tree. While he did not have any inkling if it's true or not, he suspected it to be.
For now though, he would leave some Demon Goblins to watch over the Forest Drake.
"Let's go," the A-rank monsters entered the portal to the system space, before the Archdemon took flight. He still need to seal the other 4 monsters.
Seeing the being flying away, the Forest Drake wasted no time unleashing it's potent aura, roaring so loud the Demon Goblins almost taken out by it.
