In a remote valley, there is a secret religion called "Purification Religion". The core belief of this religion is to achieve the purity and sublimation of the soul through constant dieting and fasting. The believers believe that physical weakness can make the soul closer to the gods and eventually obtain incredible revelations. Every year, the believers hold a ceremony called "Soul Purification". The core of this ceremony is a strict fasting for three months. Participants must apply to the elders of the sect before the ceremony and undergo strict examination to ensure their piety and determination. On the day when the ceremony begins, the believers gather at an ancient stone altar, surrounded by towering peaks and lush forests. The sky is covered with thick gray clouds, and occasionally a ray of sunlight shines on the devout followers. The followers are dressed in simple white robes, stepping barefoot on the cold soil, with a firm but increasingly thin look on their faces. On the altar, the elders chanted ancient hymns in a low voice, and the atmosphere was solemn and mysterious. Each follower must strictly follow the rules of the church for the next three months, gradually reducing the amount of food at each meal until they are completely fasting. During this period, they are only allowed to drink very small amounts of water, aiming to completely purify their bodies. The followers experience the ultimate test of their physical and mental limits during the long fast. Every night, hunger comes like a tide, their stomachs rumble, and the unbearable pain tears at their will. In order to resist hunger, they gather together, encourage each other, and share their stories of faith and inspiration. Some people choose to meditate alone in the cold night, trying to communicate with the gods and seek inner peace. The elders of the sect often patrol to ensure that each follower is sticking to their promise. Those who lose their will due to hunger will be persuaded to retreat, and only the most determined believers can complete the entire fasting process. After completing the ceremony, the believers will be infused with sacred water by the elders on the last day of the ceremony, which is regarded as a ritual of rebirth. As the fasting ends, the believers will embark on a pilgrimage to the mysterious cliff at the first light of dawn to save their souls, hoping to gain enlightenment and bring back new faith power. Their piety and persistence made this scene of extreme dieting and fasting one of the most sacred rituals in the sect's history.
