The Misty Forest is a monster zone that players have never stepped foot in, with an abundance of monsters. The Forest Wanderers are just the most common monsters on the periphery; the deeper one ventures into the Misty Forest, the more numerous and higher-level the monsters become.
Song Jian repeatedly farmed the Forest Wanderers. He had used over a dozen Ice Swamp Scrolls; groups after groups of Forest Wanderers fell, and near the edge of the Misty Forest, the broken bodies of Forest Wanderers piled up, layer upon layer, endlessly; even the death flames couldn't keep up with the speed at which Song Jian was farming monsters.
The respawn speed of the Forest Wanderers couldn't keep up with Song Jian's killing pace; each time he would lure out hundreds of monsters. In just over two hours, the number of Forest Wanderers Song Jian had killed had exceeded ten thousand.
