The Four Sisters Regret It

After twenty years, the real Xia family heir, Xia Yan, is found. To repay his four sisters and younger brother, Xia Hao, he endures the extreme cold and starvation of the apocalypse outside. However, he is framed by Xia Hao and thrown out to die by his own sisters. Reborn the day before the apocalypse, this time he refuses to make the same mistakes. He decisively cuts ties with his family and decides to live for himself. Awakening the Apocalypse Cut-Ties System, he uses his past memories to gather supplies and fight the freezing apocalypse, finally surviving. When the four sisters learn the truth, they regret deeply and come to beg for forgiveness. But Xia Yan has made up his mind and refuses any further connection with the Xia family.
