Dominating the Otherworld Starting with a Snake

When he woke up, Luo Zhen turned into a small green snake with bamboo leaves!
"The host wakes up and gains the Devouring Evolution System!"
"You swallowed the poisonous snake and evolved into the poisonous armored snake! You swallowed the poisonous spider and gained a new skill: poisonous arrows!"
"The host has upgraded. Congratulations to the host for gaining the blood of the serpent! You have grown wings of water and fire and become an ancient serpent!"
"Congratulations to the host, you have obtained part of the bloodline of the ancient ferocious beast Nine Infants, and obtained the summoning spell: [Demon Shadow Comes to the World]!" "Congratulations to the host, you have obtained the best sky fire, the Nine Heavens Thunder Fury Flame!"
Luo Zhen: I want to keep evolving, I want to become a world-destroying demon! ! ~
