The Sword Immortal's System

Evan Cloud unlocks the Cultivation System, growing stronger by absorbing Vital Qi. His girlfriend is the daughter of Emperor Zhu, ruler of the Zhu Clan. Her father confronts him. Evan uses the system, getting the red-tier Sky-Sundering Art, which is powerful, allows fast cultivation, but requires large Vital Qi. The punishment quest is to confront her father; failure means his neck shortens by ten centimeters!
