The Immortal Lord of the Doomsday: My Stockpile Is 100 Million Points Strong

The geomagnetism disappears and the solar wind begins to strip away the Earth's atmosphere. Under the purple sky, humans died in large numbers due to radiation. I, Lin Che, have a doctorate in geology. I first traveled through the world of immortals and practiced hard for three hundred years, and then traveled to this collapsing apocalypse and became a radiation patient with only seven days left to live. But no one knows that there is a broken immortal compass hidden in the sea of ​​​​my consciousness, which can deduce the countdown to doomsday; wearing a storage ring on my finger, the flow of time is a hundred times slower than the outside world. While all the survivors were still fighting for a piece of bread, I had used fairy runes to strengthen the fortress, used cultivation formations to warn of crises, and used rings to hoard enough supplies for ten years. The "New Eden" organization wants to capture me for experiments? "With my formation, you can't even find the door." A tidal wave of mutant beasts besieging the fortress? "Sorry, the sword array I set up is designed to kill mutants." The Survivors Alliance asks to share supplies? "Okay, in exchange for the secrets of ancient civilizations." Until that day, the compass suddenly warned: [A dormant signal deep in the earth's core has been detected. Countdown to the extinction of civilization: 547 days. And the only key to restarting the earth's core is actually the inconspicuous spiritual stone I brought from Tianxuan Continent. (No CP, focus on doomsday infrastructure + cultivation technology + civilization survival)
