There are fewer monsters in the forest compared to the vicinity of the Insect Kingdom but you can't say they are small in numbers. There are still players fighting in the forest that didn't want to participate in the totally chaotic battlefield that is outside of the Insect Kingdom's borders. To those who are not that strong, the forest is the best way to gain levels first, slowly challenge the stronger enemies, then head to the chaotic battlefield and participate in the killing as well.
While repairing the armor of Lina and Gobu, I heard a shrill cry outside. It's not near so my guess is that kit came from the battlefield where the enemies spawn.
Since Lina and Gobu's armor is damaged after trying the mantis, I recommended that they train only in the vicinity of the cabin and fight the monsters that get near here to ensure that the monsters are controlled and the enemies don't crowd in, making it troublesome if they are in large numbers.
