Foreseeing the global catastrophe, I sealed off the entire city in advance.

A series of global catastrophes suddenly descended. Extreme cold froze thousands of miles, fierce storms tore the earth apart, towering tsunamis engulfed the coast, and massive earthquakes ripped mountains and rivers apart. A zombie virus spread rapidly, countless creatures mutated wildly, bloodthirsty beasts roamed the wilderness, and the order of civilization collapsed overnight. In his previous life, Lin Chen struggled in despair for five years, witnessing the tragic deaths of his loved ones and the destruction of his city, ultimately becoming dust in the apocalypse. Reborn, he returned to three months before the catastrophe. Bearing the cruel memories of five years of the apocalypse and a premonition of the future, he was no longer cowardly or confused. He poured all his assets into upgrading the city's defenses, stockpiling endless supplies, unlocking hidden spaces, and setting up layers of deadly barriers. Earthquakes, tsunamis, extreme heat, extreme cold, and storms struck in succession; natural disasters were relentless, and man-made calamities ran rampant. In this chaotic world, people's hearts were treacherous, survivors were greedy and selfish, and alien monsters pressed closer. While the world was plunged into annihilation, Lin Chen had already sealed off the entire city, possessing endless supplies and advanced weaponry. High walls stand tall, cannons roar, and the fortress endures. A single city serves as a bulwark against the ravages of time, hunting down mutated beasts and sheltering those who survive the fall of civilization. On this wasteland of shattered civilization, Lin Chen, with his prophetic abilities, will safeguard the last sanctuary, restart human civilization, and take control of the post-apocalyptic world.
