Being OP in Reverend Insanity

In an era long after the destruction of the old Gu World, history has become nothing more than myth.

Legends speak of a forgotten age where every Venerable revived, countless new Venerables emerged, and the final war shattered Heaven and Earth. In the end, Rank Ten Destiny Gu reset the entire world, giving birth to a new Gu World where the past exists only as children's stories.

Li Tianyu remembers that forgotten history.

As an Otherworldly Demon reborn into this new era, he possesses no powerful backing, no heaven-defying aptitude, and no destined fortune. Born with the lowest D-grade aptitude, his path to immortality should have ended before it even began.

But talent and aptitude are not the same.

After decades of relentless research, Li Tianyu creates a Gu unlike any before it—Ember Spark Gu, the first Gu of the Dao Blaze lineage. By burning the Dao fragments contained within sacrificed Gu worms, it can deduce Gu recipes, killer moves, cultivation methods, inheritances, and countless other forms of knowledge directly from the Great Dao itself.

Knowledge, however, is never free.

Every deduction demands an unimaginable price.

Thousands of Gu worms.

Rare resources.

Even Immortal Gu.

To continue advancing, Li Tianyu must gather resources on a scale that even super forces would find terrifying.

His first masterpiece, the Primordial Flame Seed Gu, transforms his body into the Primordial Flame Physique, allowing all Dao marks to coexist without conflict while strengthening Fire Path. His ultimate goal is even more ambitious—to recreate and surpass the legendary Sovereign Immortal Fetus Gu, forging a perfect Fire Path body capable of standing above every Venerable.

In this new era, Fire Path will imitate every other path.

Flames will steal.

Flames will heal.

Flames will deduce.

Flames will dominate.

This is the story of a refiner who begins with nothing but a weak aptitude and a single spark, yet seeks to burn his name into eternity and become the first Rank Ten existence of the new Gu World.
