After the top VR player Lin Ye ("Night King") successfully killed the final BOSS in the game, he accidentally traveled through time and became the ninth-generation Abyss Demon King he had just defeated, but with only 1% of his power left. After waking up in the "Throat of the Abyss" in the Demon King's City, the system activates the main mission "The Demon King's Resurrection" and warns the first batch of "braves" (the "Purification Team" of the Light Camp) that will arrive in seven days. Faced with internal and external troubles, Lin Ye quickly turned from shock to calmness, and began to deal with it with his rich game experience and tactical acumen. He summoned the loyal butler Mogan and three demon generals - Soul-Eating General Lilith, Skeleton Commander Barton, and Shadow Mistress Ella to show his leadership.
Lin Ye abandons the toughness of the traditional devil and prefers strategy and psychological warfare. With his "player" thinking of "victory first" and "wretched development", he successfully persuaded Patton, who advocated frontal attack, to change his mind and determined to help. Lin Ye originally planned to use the environment of the Wailing Ancient Road and Lilith's illusion to weaken the "Purification Team" led by the legendary knight "Sword of the Dawn" Auston. However, intelligence showed that the enemy had added Hieronymus, the "Executor of the Holy Word" who could restrain darkness and illusion, forcing Lin Ye to adjust his strategy. He listed Hieronymus as a priority target and planned multiple strikes: Lilith's precise mental harassment, Barton's placement of physical traps, and the more innovative introduction of "putrid mud" poured from the upwind vent to disgust and disturb the enemy. The core plan was for Lin Ye to personally detonate the crystal array at the exit of the ancient road, creating a large-scale chain landslide, and mix it with metal fragments and stinking tar to enhance lethality and psychological deterrence.
