The Ancestor of All Demons

Shi Feiyang finds himself transmigrated into the body of a demonic dragon, tasked with guarding the mysterious heavenly book atop the treacherous Dinghu Peak in the Shu Mountains.

Bound to a path of cultivation, he must master cruel and arcane arts hidden within the Heavenly Book Supplement to survive the inevitable arrival of powerful cultivators. As he balances the pursuit of immortality with the brutal law of the jungle, Shi Feiyang transforms from a vulnerable captive into a predator, refining his swordsmanship, alchemy, and dark spells while waiting for his enemies to fall into his trap.
