Several of the Rainbow Birds died a minute after they started to explore the valley.
Millennial Beasts at their peak stages, Pseudo-Myriad Beasts, and Myriad Beasts could be found all over the valley.
Beads of sweat formed on William's forehead as he checked the map on his status page. Orange, red, and purple blinking dots littered the entirety of the map. A single glance was more than enough to tell William that he was surrounded by monsters in every direction.
The orange dots represented the monster at the Peak of the Millennial Rank. The red dots represented monsters that were only half a step away from becoming Myriad Beasts. The Purple dots, on the other hand were bonafide Myriad Beasts, and William would be stupid if he were to carelessly traverse their territories.
According to Optimus' scan, most of the Myriad Beasts were located in places that held resources, similar to the Golden Fruit that the Diabolical Hell Ape sought out.
