Immortal Venom Ascension

In his past life, he was a master of toxins who died chasing the ultimate goal: perfect poison immunity. Now, he has been reborn into a world of soaring immortals and legendary blades-trapped in the frail, "trash" body of a high-ranking disciple in the Azure Sword Pavilion.
In this clan, the sword is pure, and weakness is a sin. Mocked by his genius brother and disowned by his cold-hearted father, the original boy chose to end his misery by consuming a cocktail of the world's deadliest poisons.
But he didn't die. Instead, he woke up.
With a mysterious Immortal Venom System guiding his evolution, he discovers that his broken meridians aren't a curse-they are the perfect vessel for a forbidden path. While others refine pure spiritual Qi, he converts every toxin, every beast trait, and even his enemies' elemental attacks into Venom Qi.
He doesn't need a sword. His hair shoots like poisonous needles, his skin burns with corrosive toxins, and his nails are sharper than any forged steel. From the depths of his secret Poison Garden, he breeds mutated insect sovereigns and reptilian disasters, building an army that breathes plague.
To the world, he is a walking catastrophe. To the Azure Sword Pavilion, he is a heretic. But to those who dare cross him, he is the Venom Sovereign-the man who proved that what kills the world only makes him a God.
