Chapter 137 - Run 

Now, probably only 30 monsters remain. 80 monsters attacked him previously, but now only 30 left. Sam, who was fighting with them, suddenly felt danger from his back. He instantly twisted around and avoided the incoming attack. It was a dark ball that someone shot toward him.

Sam jumped from that place. He saw two figures coming in his direction. One human figure and the other one dog. 

"So, finally, the bosses arrive." Sam thought. Now, this is getting tough for him. He was powerful, but he was just the only person. 80 peak E-grade monsters and 2 early D-grade monsters, fighting with this many monsters, really makes you tired. He needs to recover his full energy, only then he can once again fight with them. 

Sam looks at the peak E-grade monsters and the early D-grade monsters that were coming toward him. He didn't delay and activate his concealment technique. Instantly, he vanished from his place and those monsters instantly listed their target.
