A formation capable of dealing with a monster of the third rank required the activation of a great deal of mana. It would take the member of the "Demonic Tree" about five minutes to fill it with mana and activate it.
Evan watched their actions closely. There was a monster, the members of the "Demonic Tree" and Evan near the ruins. The monster didn't know that it would be attacked soon, the members of the "Demonic Tree" didn't know that Evan was watching them, and as for Evan, he didn't know that there were assassins following him.
<This formation is very formidable, it will be able to kill or at least stun the monster. That's not really a good thing...>.
If none of the "Demonic Tree" members were injured, Evan would find himself in a difficult situation. It was too dangerous to just show up in front of them and try to talk. Evan was annoyed, there was nothing he could do about it.
