From Now On, Enter the Global Counterattack

In an imaginary world, Jiang Yan was reborn. He was reborn a year before the alien civilization invaded. In one year, alien civilization will come to this planet. At that time, the gap in weapon levels made the humans on the planet a piece of cake. If aliens are allowed to slaughter us, human civilization will eventually perish. In order to prevent history from repeating itself, the first thing Jiang Yan did was to contact the country's top leader. Use all the resources in the country to build a steel Great Wall to resist alien civilization. Prepare to give a big surprise to the alien civilization that will arrive here in a year.
