In his past life, Ye Ke was framed and plotted against by others, dying with grievances. He is reborn back to the time point before everything happened, gaining a golden finger that produces water. Seizing the opportunity during the final window period before the apocalypse arrives, he uses information about the upcoming apocalypse to build an oasis safe base, hoarding food and building granaries, growing seedlings and digging canals, turning the wind-blown and sand-filled wasteland into an impregnable oasis safe base. The people he wrongly trusted, the feelings he wrongly bestowed, and the opportunities he missed in his previous life—this lifetime, he takes them back one by one.
