When Yu Feng of Liaoning Province in China found a dying black snake in the grass outside his home, he made an unusual decision that would change his life.

Yu brought the snake inside, determined to give it another lease on life. Little did he know the snake would soon return the favor, according to the website Ananova.

"I treated it with herbal medicines, and in 20 days it recovered," Yu said.

Once the snake recuperated, Yu decided to release it back into the wild. He took the snake to a nearby mountain more than a mile away.

But the snake had grown attached, Yu says, and the next morning, it was back outside his house. He tried two more times to set it free, but it always came back.

"People around me said the snake had come back to repay my kindness, so I kept it."

The snake, dubbed Long Long, became the family pet, and before long, it had a chance to return Yu's favor.

One night, while Yu was sleeping, he says he felt something cold on his face and awoke to find Long Long.

"He had never woken me up before, but I was so sleepy I went back to sleep. But Long Long grabbed my clothes with his teeth and whipped the bed with his tail.

"Then he went to my mother's bed and whipped her bed with his tail. I woke up then and smelled something burning, and saw my mother's electric blanket was on fire so I leapt up and turned it off."

Though local reptile experts say snakes simply don’t have the brainpower to behave in such a way, Yu insists the snake saved his life. These days Long Long is never far from his side.
