He felt an unprecedented despair. Cold, hunger, and illness were like three ruthless claws, tightly gripping his throat. He didn't know how much longer he could hold on. Every breath felt like dancing on the edge of a knife, and every heartbeat was accompanied by severe pain.

Xiao Yi closed his eyes, memories of the past echoing in his mind. Everything he once had—family, friends, a warm home—was now gone. He felt like a lone boat, drifting on the vast ocean, with no one to rely on.

However, even in this endless despair, Xiao Yi still had a glimmer of hope deep in his heart. He prayed silently, hoping that someone would find him in this doomsday and bring him a glimmer of hope. But he also knew that such hope was as slim as a shooting star in the night sky, fleeting.

He can only rely on himself. Xiao Yi gritted his teeth and tried to concentrate. He began to recall the survival knowledge he had learned in the past, thinking about how to save himself in this desperate situation. He knew that he had to cheer up, otherwise he would really have no chance to see the sun tomorrow.

So, Xiao Yi began to move his body with his weak strength. He tried to find something edible, even if it was just plant roots or animal remains. At the same time, he also tried hard to search for possible medicines or herbs in the shelter, hoping to alleviate his condition.

In this extremely cold apocalypse, Xiao Yi becomes his only savior. He fights the disease with his willpower, and fights despair with his weak strength. He believes that as long as he does not give up, he will find hope for survival.

Just as Xiao Yi's consciousness gradually fell into chaos and the fire of life seemed to be about to go out, a sudden knock on the door echoed in his ears like the sound of nature. At first, he thought he had fallen into hallucination, but as the knock on the door became clearer and clearer, Xiao Yi's consciousness gradually regained a trace of clarity.

He struggled to sit up from the blanket and used all his strength to move towards the door. His fingers trembled as he finally touched the cold door handle. Xiao Yi took a deep breath and slowly opened the door.

Outside the door stood a strange man. He was wearing thick winter clothes, a mask and goggles on his face, revealing only a pair of deep eyes. The man was carrying a small bag filled with food and medicine. The moment he saw Xiao Yi, he smiled slightly, with a warm light in his eyes.

"I'm here to save you." The man's voice was low and firm, as if a warm current flowed into Xiao Yi's heart.
