The Funeral Sky Coffin Chose Me, and I Became the Strongest Daoist Venerable in the Nine Heavens

Looking for a Primordial World Story About a Sleeping Ancient Patriarch Who Is Invincible from the Start and Shocks the Entire Realm

Transmigrate to the time when Pangu created the heavens and the earth, even earlier than when Pangu took form. Become the first Chaos-born god or demon to take form, and be invincible from the start. The god-demon is a dragon who sleeps until Journey to the West, then wakes up and stands up for the dragon race. (Note: They must sleep until Journey to the West to wake up.)
