Global Wasteland: I Obtained A Top Tier Shelter

The world was destroyed by meteorites and everyone on Earth transmigrated to a wasteland.
The wasteland would encounter an unpredictable catastrophe every seven days. Some of the catastrophes included the great flood, ice age, invasion of demonic beasts and plague of plants.
In order to survive, mankind had to build more advanced shelters.
Lin Yue awakened the 100 Percent Drop Rate System, allowing him to live a very different life from the others.
Other people lamented, “The drop rate is too low, isn’t it? I have killed 50 mutants, yet I still have not gotten any drops!”
Lin Yue lamented, “I have way too many drops and my item list is now full. Could it be that I have to upgrade my shelter and build a warehouse for all the drops? Tsk. That’s so troublesome.”
