Global Fog: Get the StarCraft System at the start

This is not my original work. I just found this story on a MTL site. I'm just translating this for fun . Thanks

Synopsis:

The grey mist enveloped the entire planet, all communications were destroyed, and most humans were infected by unknown viruses and turned into zombies that feed on flesh and blood, but this is just the beginning. What followed was that the monsters in the legend walked out of the spatial passage in the gray mist. The surviving humans used the weapons and equipment surviving in the peaceful years to build shelter after shelter to block the invasion of the grey mist while preserving most of the human fire. At the beginning of the world's end, Lin Yubai obtained an interstellar command center. After months of hard work, he finally won the first Marine.
