Incredible! The Doomsday Prophecy Came True

[Post-apocalyptic + Rebirth + Supernatural Pocket Dimension + Stockpiling Supplies + Interstellar Catastrophe + Biohazard Crisis + Rescue Alliance] In the vast universe, humanity is no more than a drop in the ocean, as insignificant as dust. Natural disasters and human calamities, fortune and misfortune, can strike at any moment, and no one can predict them. Volcanoes erupt around the globe for unknown reasons. Acid rain runs rampant, earthquakes and tsunamis strike again and again, and new bioengineered species appear one after another. The apocalypse descends, reducing the entire city to rubble. Chewing grass roots and tree bark, or stewing ice in volcanic lava, is just an ordinary day. People even butcher their fellow humans and swallow unknown mutated bioengineered species alive. To stay alive, people will do anything, without restraint. By chance, Zhou Ziye steps onto the S-cycle timeline and is reborn three months in the past. Reborn once more, he decides to turn ruthless and take revenge, never again playing the self-sacrificing saint. Not enough supplies? He awakens a supernatural pocket dimension containing ten thousand mu of grain storage and frantically stockpiles supplies. Nowhere to hide? He breaks into the underworld and builds an S-class sanctuary, as comfortable and safe as a paradise beyond the mortal world. Volcanoes erupt, lava boils, and nothing can grow? He summons a thousand qing of ice fields to stew and preserve the water of life. Tsunamis and solar storms run rampant? He leaps into a black hole, steps onto the S-cycle timeline, and searches for the stop button, one clue at a time! His gold-digging ex-girlfriend wants to get back together and trick him into helping her survive? No way! His childhood friend is willing to endure humiliation just to get into the sanctuary? Dream on! Bioengineered virus expert: Zhou Ziye, if you can help us wipe out these bioengineered species, we'll worship you as a god! Zhou Ziye: Heh... You really know how to spin a tale! The age of making gods is over. Keep your titles and bestow them on each other. I want to be a bear everyone despises, holed up in the underworld sanctuary and enjoying my post-apocalyptic life!
