Reborn in the extremely cold apocalypse, I installed the most useless welding system.
In my previous life, I welded doors and tanks for the base, but ended up freezing to death on the city wall.
After returning from rebirth, the system asked me what I wanted to weld this time.
I lit the welding torch, looked at the base boss who had betrayed me, and smiled slightly:
"Weld your coffin boards shut."
