Lin Feng, a 22-year-old factory technician, unexpectedly enters the world's first holographic online game, "Apocalypse." Through a bug in the newbie gift pack and fragments of his past life memories, he awakens the only SSS-level mutated talent in the entire server—Future Appraisal. This unconventional talent not only allows him to view a target's complete attributes and hidden information, but also predicts ten minutes into the future, unlocks item evolution paths, and senses bond compatibility, becoming his ultimate weapon for turning the tide of battle.

From scavenging rare items and raising exotic pets in Dawn Village to earning his first fortune at the Glory City auction house, Lin Feng rose rapidly with his ruthless and decisive style, slapping the faces of whales (players who spend a lot of money on in-game purchases), and establishing the guild [Apocalypse Pavilion]. He repeatedly created miracles in territory wars and cross-server battles. As his strength increased, he gradually discovered that the barrier between the game and reality was dissolving. "Apocalypse" was actually a selection mechanism for the strong left by an ancient civilization, and otherworldly forces were infiltrating Earth through the game.

Teaming up with elemental mage Su Muxue, berserker Zhao Pangzi, assassin Lao Dao, and other companions, Lin Feng unlocks his ultimate talent form, leading the Human Guardian Alliance against the hegemony of the [Temple of War] and the otherworldly invasion of the Shadow Overlord. From guild wars in the game to survival battles in reality, he relies on his accurate predictions and strategic planning with his appraisal skill to break through the Bronze, Gold, and Diamond realms, ultimately becoming the "Guardian of Apocalypse" who connects the two worlds. While protecting Earth, he uncovers the ultimate secrets of ancient civilizations and the otherworldly invasion.
