An eight-magnitude earthquake tore through Jinshi, high-rise buildings collapsed into ruins, "rock spiny insects" that emerged from the ground and "rotten rats" spawned by pollution were rampant, and the survivors fought for half a biscuit. {Su Ran} woke up in the ruins of the fighting gym, broke the neck of the rotten rat with his bare hands, and rescued the trapped Gu Yan and Ye Tang. When the water was cut off, she led a team to break into the supermarket to grab bottled water; when Zhou Hu surrounded the shelter, she used a short blade to fight one against eight; when rock-thorn insects invaded the grain depot, she relied on her fighting skills to kill the insects and protect the food. When contact with the outside world was lost, Su Ran grasped the broken military spur and said, "If you want to live, just follow me and defend!" The trio led the survivors to build defenses, find water sources, and try to survive in the city abandoned by the natural disaster.
