Mortals Can't Cultivate to Become Immortals, so I Will Practice Demonic Cultivation Instead

In a future city where immortality is monopolized by the powerful, Lin Feng, a poor student, has spent everything he has to fulfill his family's hopes, but he has trouble cultivating immortality because he has no background. When he witnessed the uneducated and incompetent dandies easily taking away everything including his sweetheart, he was forced into a desperate situation and resolutely stole the forbidden drug from the academy. After taking an elixir that could cause a mortal to explode and die, his extreme resentment not only failed to destroy him, but instead caused him to fall into the devil's path and gain the power to subvert everything. From then on, he vowed to use his demonic body as a blade to cut through this rotten way of heaven and its rules.
