Everyone's Crazy, but I'm the Demon King

The heart holds countless thoughts:

Greed, anger, delusion, envy, malice, recklessness, depravity, killing, cowardice, despair, aversion, doubt, domination, arrogance, bestiality, chivalry...

Arts are divided into ten categories:

Conventional, natural, biological, mental, supernatural, ancient, ingenuity, combat, mythic, and beyond classification.

When a thought reaches its utmost extreme, becoming utterly pure and utterly mad, it becomes a Frenzied Thought.

Only those with Frenzied Thoughts can become Frenzied Cultivators and seize Life Arts.

Frenzied Cultivators cultivate the Frenzied Dao.

Life Arts are one's innate Dao arts.

As for demons, they follow their hearts freely, without restraint, doing whatever they please.

Ling Yue, who transmigrated here for no apparent reason and inexplicably possesses a proficiency panel, an infinite health bar, and an infinite mana bar, was born with the demonic Frenzied Thought and a nature so free that he defies all law.

In this multiverse ruled by a host of cultivation madmen, each possessed by their own kind of insane obsession, he will set out from a small world where spiritual qi has only just revived, then stride across boundless spacetime and single-handedly slaughter his way through infinite dimensions.

Condense obsessions, seize karmic fruits, grasp profound essence, shatter the will of Heaven, suppress the cosmos, and sweep across the multiverse.

Refine obsessions into bricks and build towering cities; use fruits as bricks to raise immortal cities; stack essence into pillars reaching immortal mountains; pave the Dao into steps ascending to the Celestial Court.

Ling Yue: "Sorry, your full strength is only enough to warm me up. I'm the ceiling of what you can ever achieve. You're the one who has to challenge me."
