Later, when his grandfather wanted to dig him out, he broke the rope desperately and ran out.

He ran, ran, ran. The wind howled, the snowflakes flew, and his vision began to blur. The road ahead became increasingly difficult to see. His breathing became rapid, his heartbeat accelerated, and his body was exhausted, but he didn't dare stop.

He didn't know how long he ran until a chill came over him and he lost consciousness. His body fell limply into the snow, and the snowflakes fell on his face, cold and icy, as if reminding him to return to reality.

He tried to stand up, but his body wouldn't respond. He felt cold and exhausted, and his heart was filled with despair. He wanted to shout, but the sound was stuck in his throat and couldn't come out.

Time seemed to stop, and his consciousness gradually faded. He felt his heartbeat and breathing become weaker, and his body gradually lost consciousness. He knew he might die, and the thought filled him with fear.

Suddenly, he felt a force pushing him. He opened his eyes and saw a stranger looking at him. The man was wearing a thick coat and holding an umbrella.

"Are you okay?" the man asked.

He nodded, but no sound came out.

"Do you need help?" the man continued.

He nodded again, and this time his voice finally came out, "I...I need...help."

The man helped him up and gave him a cup of hot water and a piece of chocolate. He slowly regained his strength and felt his life come back to him.

"Thank you," he said gratefully.

"You're welcome," the man said with a smile, "You need to find a safe place to rest, otherwise you might faint again."
