- Description from novelbuddy

This is the story of the youth Wen Leyang, born into the family with an expertise in the cultivation of the Art of Poison.

Empires rise and fall on the Yulan Continent. Saints, immortal beings of unimaginable power, battle using spells and swords, leaving swathes of destruction in their wake. Magical beasts rule the mountains, where the brave – or the foolish – go to test their strength. Even the mighty can fall, feasted on by those stronger. The strong live like royalty; the weak strive to survive another day.
