Black Pine Ridge.
This place is located seventy miles west of the Mountain of Ten Thousand Poisons. Originally, it was a vast forest, swarming with tigers and wolves and rife with ferocious beasts.
Latter, a Poison Master settled nearby in Black Pine Ridge for the sake of convenience, so that he could capture poisonous creatures from the Mountain of Ten Thousand Poisons at any time to concoct his poison, and also catch some wild beasts from the mountain to test his poison on.
Just a few years passed, and the wild beasts have disappeared from the mountain. The luxuriant plants were replaced by the fearless, highly toxic black pines that continued to grow and propagate. Over a long period of time, it turned into a gloomy and frightful Black Pine Ridge.
Currently, there are more than just one, but rather hundreds of poison masters dwelling there. They belong to dozens of different Poison Master traditions, both large and small.
