Chapter 87 - The Strange Rock

Teacher Michael suddenly noticed some movement not far away from that location which made him very alert. Immediately, he created a barrier around that place and even prepared himself to attack those incoming enemies. 

David, who is beside teacher Michael, also became startled. He also even prepares himself to fight the incoming enemy. 

Sometime ago, with the help of teacher Michael, he just killed a group of level 30 Monsters. After that, he was busy collecting the body parts of those monsters when the barrier was created around him. 

Both teacher and student patiently wait for the incoming enemies. Teacher Michael somehow became relaxed when those incoming enemies came close to their place. 

It looks like he is able to observe those enemies and that makes him realize they are not enemies.
