Return of the Immortal King: Five Years Before the Arrival of Another World

Five years later, a rift in the alien world suddenly came, spiritual energy surged, and demons were rampant. Humanity has devoted all its efforts to fight bloody battles, but is still retreating steadily. The country has fallen, civilization has collapsed, and hundreds of millions of creatures have become food and slaves for alien races. Jiang Xuan, the immortal king of a generation, died at the last line of defense. With endless regret, he reversed time and returned to the five years before the catastrophe. Returning to my boyhood, no tragedy has happened yet, and the crisis is still lurking in the shadows. This time, he will no longer watch his relatives die, his friends die tragically, and the world fall into purgatory. Relying on the Immortal King's thousand-year experience and past life memories, Jiang Xuan quietly laid out his plans in the city. Set up spirit gathering arrays, refine body-tempering elixirs, clear out extraterritorial insect eggs hidden throughout the city, and eradicate impending disasters in advance. Mutated beasts appear one after another, the aura of heaven and earth slowly awakens, national institutions notice changes in the world, and undercurrents of multiple forces surge. Five years buffer period, race against time. Start from a small city, accumulate resources, cultivate strength, and eliminate hidden dangers. When the alien army arrived as expected and everyone was in despair, an immortal king who had been dormant for a long time stood in the world, blocking all the races in the sky and protecting the entire Blue Star!
