A one-year countdown in red appeared on the big screen in the middle of the underground city. When the countdown reaches zero, it would be the end of Earth. This was humanity's last preparation time, so every aspect was working day and night.
Currently, the Moon Ruins have already been opened to Ruins 9. This was also the largest ruin discovered by humans with the most hidden treasures.
The exploration team of more than 30 people entered the ruins one after another. Every time they discover a ruin, it might add a heavy layer to the defense of Earth.
Now that all the cultivators were immersed in cultivation, the country could also focus all its energy on technological innovation. It was very difficult to make any obvious breakthroughs in terms of weapon configuration in a short period of time. Then, exploring the ruins and obtaining as many resources as possible and finding more clues about aliens would also lay a huge foundation for the victory of this battle.
