Top survival expert Lin Wei was reborn three months before the world was plunged into an eternal night of extreme cold. In her previous life, she was a lone wolf surviving, and finally died in the coldness of betrayal and humanity. In this life, with memories and resources in hand, she chose to make her plans public in advance as a "hardcore survival anchor". Her lens is not only to show how to build a doomsday fortress, but also to accurately save those kind geniuses who were extinguished like candles in their previous lives - depressed scientists, ruined surgeons, and marginalized agricultural students. When blizzard and darkness engulfed the world, her live broadcast room became the only source of light. Natural disasters are raging, and people's hearts are filled with ghosts. This time, she no longer walks alone. In this darkest era, she wants to use live streaming to build a tower, gather people's hearts, and become a beacon that pierces the eternal night and guides the survival of civilization.
