I Submitted the Magnetic Meteor Era, and the Whole Nation Launched the Sky-Mending Plan

【Dual portals + doomsday countdown + nationwide infrastructure drive + pure power fantasy + foreign countries get humiliated】 Su Chen acquires a portal leading to Blue Star ten years in the future. The Earth's core is in turmoil, its magnetic field has vanished, and cosmic rays are bombarding the surface. Disaster has destroyed human civilization… Exposure to radiation from the other side leaves Su Chen with skin cancer, and his life is now on a countdown! With his life drawing to a close, Su Chen decisively turns the portal over to his country! The entire Xia Kingdom is stunned, then immediately launches the Heaven-Mending Project, bringing the myth of Nüwa mending the sky to life! The magnetic field is gone? All 1.4 billion people of Xia join the Nüwa electromagnetic array and refine stones to mend the sky! Earthquakes strike? Xia responds by bringing out a planetary tunnel boring machine and building an underground city beneath Jiuzhou, a thousand meters below the surface! When the Magnetic Cataclysm Era finally arrives, foreign countries descend into panic and chaos, while life in Xia's underground cities is filled with music and dancing! Countless foreigners beg on their knees: “Please, let us in to take shelter!” Xia refuses firmly: “Xia is responsible only for the safety of its 1.4 billion Chinese citizens!”
