Efficiency
Infact at that time killing Demonic beast was almost impossible to kill, but now he didn't have to waist his time planning his next course of action.
Even with a low grade weapons he will be able to easily take down any beast.
His point rose to 800 after he slayed the last demonic red tailed monkey, without hesitating he started towards the other groups and Slayed them so easily that it felt like he was a killing machine flashing through the forest and taking the life of the beast that he saw.
Meanwhile, at another part of the forest was the same dude who has the flame power staff swinging his staffs and killing a group of grade 3 demonic deer.
Although it was just grade 3, he was lucky that they were in a group and thus he managed to gather 300 points after killing all of them, moving on to the next area that he smelled the scent of a demonic beast.
