Survival in the Fog? but Collecting Supplies Relies on Raids and Raids?

[Survival + No heroine + Unlimited flow + Decisive killing] Billions of people around the world were suddenly thrown into a world of deathly silence and mist. There were no naturally produced materials and no safe escape route. The only chance of survival for all survivors depended on the special copy of "Search, Strike, and Evacuate" that was opened every day. Every morning in the early morning, the system refreshes three dungeon worlds with different difficulties. Survivors need to make a choice within one hour. After confirming the transfer, they must complete the complete process of "searching for supplies - fighting threats - arriving at the evacuation point" within a limited time. If they exceed the time limit, they will be permanently stranded, with no possibility of survival. The regional assessment of a thousand people comes every seven days as scheduled, and the bottom hundred ranked are directly wiped out by the system. After the assessment, all members are reshuffled, and the competition for survival is endless. From the abandoned community with eternal dusk to the silent library with whispers of dust, every dungeon is a gamble where resources and murderous intent coexist. —— Su Mo, an ordinary civil servant, was only assigned a simple tent with air leakage at the beginning of time travel, but he unexpectedly awakened the ability "Awakening of Talents" outside the rules. He does not have world-destroying combat power, nor does he have unlimited supply plug-ins. He only relies on repairing defective equipment, giving temporary special attributes to ordinary items, and maximizing profits from the most basic resources. Add "Shocking Scream" to the Broken Short Spear to sweep away the rot rats, and add "Purifying Flame" to the old lantern to burn the Dust Guardian. In the law of the jungle where everyone is in danger, he upgrades his shelter, hoards core resources, and deals with other survivors. He uses calmness as a chess piece and strategy as a pawn. In the fog-shrouded life and death game, he steps from the bottom to a rookie to find his own path to survival.
