When he woke up, Luo Zhen became a green snake with bamboo leaves!
“The host wakes up and gains the devouring evolutionary system!”
“You swallowed the venomous snake and evolved into the poisonous snake! You swallowed the poisonous spider and gained a new skill: poisonous arrow!”
“The host is upgraded, congratulations to the host for acquiring the blood of the snake! You have grown water and fire wings and become the ancient snake!”
