The game has come to reality, the rules of the world have been subverted, and Blue Star has entered the era of job change for all!
Demons and monsters are rampant. People can continuously upgrade and become stronger by plundering demons and slaughtering monsters.

Open talent panel:
"Chain Saw Demon: Pull the engine on the chest and turn into a chainsaw man. All attributes are greatly improved."
"The Immortal Soul: Whether you are dead or seriously injured, just pull the engine on your chest, or drink your blood, and you can stand up and continue fighting!"
"The Power of Fear: The increase of the enemy's fear of you will slightly increase the attributes of all aspects!"
