I Delivered Food to the Primordial World, and Devoured Junhong from the Start

Lin Jun, a food delivery rider, is hit by a car and sent flying. When he opens his eyes again, his soul is being torn to shreds by a chaos storm. Suddenly, a voice rings in his ear: “Ding! The Strongest Dao Ancestor System has activated! Dying Chaos Demon God ‘Junhong’ detected. Soul compatibility: 99.99%!” “Recommendation: devour him immediately, take his place, and inherit his Great Dao origin, cultivation abode, and supreme treasures!” Should he let his soul dissipate, or possess the Demon God and become an early Primordial being with top-tier innate origins? Lin Jun figures that hesitating for even one second would be disrespectful to eternal life, and immediately shouts, “I'll devour him!” From then on, the Primordial Era loses one remnant soul of a Chaos Demon God and gains a “Junhong” with a modern soul. With Mount Yujing as his cultivation abode, a fragment of the Creation Jade Disc in his hand, and the Taiji Diagram above his head... he's fully equipped from the start! But he knows that the Great Dao wound left inside him by the Pangu Axe, the karmic connection he can sense in the unseen, and the scrutiny of the Heavenly Dao's laws could bring him to ruin at any moment. Still, it seems none of that is a big deal...
