Top-tier pro booster Ying Huaixu mistakenly selects the Primordial difficulty and time-travels into "Primordial Immortality Chronicles". The exit key disappears, and he can only rely on the game system, plot foresight, and mutated ice-path sword spiritual root to survive. Starting from Ping'an Town, he befriends Ye Ningshuang, breaks through the nether ghost secret realm, enters Divine Firmament Sword Sect, eradicates the Thousand Mechanisms Gate, and rewrites the fate of fellow disciples dying in battle. As the Asura Hall and the Vast Sky conspiracy emerge, he leads the team to guard the mountain, venture into the cold pool, battle meteorite beasts, and expedition into the starry sea, ultimately destroying the star-swallowing boundary gate. When the exit key appears again, he chooses to stay. The entire drama is dense with thrilling highlights, constant twists, and combines sect counterattacks with righteous-versus-evil gaming.
