Before Traveling Through the Doomsday, Start by Reporting to the Country

When I woke up, I had an extra memory in my mind - from the tenth year of the end. At that time, I stood on the ruins, watching the invading monsters, watching that there were only 30 million compatriots left, and watching that civilization was on the verge of extinction. Then, my future self used up my last strength to send hope back to the present. It's called Jiuding. It gave me a body beyond human limits, gave me the ability to predict the future, and gave me the final warning: "In 60 days, the end will come." I found my comrades and got resources. But I soon discovered that the most terrifying thing was not the alien monsters—— But a traitor among mankind. The countdown begins, this time, I want to rewrite the ending.
