1 Month To Doomsday But I Awakened Before That 1M2D

"Su Chen transmigrated to a time one month before doomsday. It was an ordinary world, yet Su Chen awakened the Doomsday Login System!
The system even reminded Su Chen that there was only one month left before doomsday. He would obtain rewards as long as he logged in every day, logged in naturally, and logged in at dangerous places.
""Ding! Your automatic login has been registered. You obtained the ultimate brawling technique!""
""Ding! You successfully logged in at a volcano. You obtained Fire Fist!""
""Ding! Your automatic login has been registered. You obtained doomsday resources—100 bottles of mineral water!""
After the catastrophic event, monsters roamed the world, and the space that humanity had for survival got infinitely smaller.
Even those who were awakened felt miserable as they started to train.
However, by this time, Su Chen had reached his peak and had nothing else to do. Even the refuge center he was rewarded with had become the safest place in the world!"
