Bai Feng, a veteran player and lore expert, finds himself transmigrated into the most desperate timeline imaginable: the Pre-Civilization Era of the Honkai universe. With the Finality reset looming and the terrifying Herrscher of Corruption preparing to annihilate the last human cities, survival seems impossible. Just as despair sets in, he awakens the Super Popularity Live Streaming System.

His lifeline? Broadcasting his reality to audiences across parallel dimensions. His first guest is none other than Bronya Zaychik from the Post-Honkai Odyssey era, now a mature game developer ready to assist her former Captain.

Together, they project their stream into the past, captivating legendary figures like Kevin, Elysia, and Mei, while simultaneously connecting with the playful Silver Wolf from the Honkai Star Rail universe. As Bai Feng leverages future knowledge and cross-dimensional commentary to alter fate, he must navigate ancient conspiracies and cosmic horrors, turning a hopeless timeline into a stage for salvation through the power of live interaction.
