Lin Yuan is a twenty-two-year-old college graduate living with his maternal grandmother in Luoyang. His parents work overseas, leaving him to raise his younger sister, Lin Xiaotian. Lin Yuan possesses an unusually youthful and delicate appearance, often mistaken for a student. While preparing a hot pot dinner, he activates the Affix System, which reveals that in three years, the world will face an invasion of advanced martial arts and a resurgence of spiritual energy, leading to an apocalyptic dark age. The system grants him the talent Information Viewing, allowing him to see the future state of objects and beings.
Using this ability, Lin Yuan discovers that his current reality is a precursor to a horrific future. He learns that the old willow tree in his neighborhood will evolve into a demonic entity that harvests human brains. He also sees his own future death as a Mad Fire Living Dead, corrupted after dying as a Light-type extraordinary being. Determined to change his fate, he completes system missions to acquire powerful entries. He obtains a Spirit-level Spatial Pocket, which he uses to stockpile food and supplies. By exceeding mission requirements, he upgrades the pocket to a Large Spatial Pouch with 125 cubic meters of storage.
Lin Yuan then encounters a hairy crab that will evolve into the Azure-Clad Demon Mother, a mid-stage Spiritual Entry monster. He kills and consumes it, gaining the Excellent-level entry Precognition Vision, which allows him to view events twenty-four hours into the future. Using this ability, he witnesses the monster tide attack on Luodu Fortress three years later. He identifies the Old Willow Tree and a colony of Black Armored Demon Ants as threats and eliminates them using salt water, herbicides, and boiling water. This grants him the Innate Ant Strength entry, tripling his physical attributes.
He also meets Qin Qinglang, a seventy-year-old martial arts master who will become a Peak Spiritual Entry expert in the future. Lin Yuan becomes his apprentice, triggering a quest that increases his learning efficiency by one thousand percent. He learns that Qin Qinglang possesses Flawless-grade martial arts scriptures. Meanwhile, his cousin Lin Ying works for Bureau 314, a secret organization handling supernatural events. Lin Yuan discovers that Lin Ying is destined to die in an attack orchestrated by Wei Tao, leader of the Progressive Faction, on October 14, 2027. By persuading her to accompany him to the martial arts school the next day, he alters her timeline, saving her life and gaining the Spirit-level Righteousness entry.
Lin Yuan also finds a stray black cat that will evolve into the Seductive Banshee, a Death-level threat and key planner of the monster tide. Instead of killing it, he decides to keep it and has it sterilized, hoping to alter its demonic nature. He continues to poison the Old Willow Tree with salt water and cycloazinone to prevent its transformation. With his new entries, enhanced physical abilities, and knowledge of future events, Lin Yuan prepares to navigate the coming spiritual energy revival. He aims to grow stronger, protect his family, and prevent the apocalyptic fate foretold by the system.
