What's the story of the tortoise and the snake?

[1] The story of the snake and the tortoise

A python and a small poisonous snake are friends.

They found a huge turtle on the side of the road that day.

Brother snake thought, such a big man is really a delicious meal.

The python said, I'll deal with him.

So the boa constrictor performed a stunt and wrapped the turtle firmly with his body. The tortoise has already shrunk its body into its shell, and no matter how the python cuts, it can't hurt the tortoise.

The frustrated python panted and climbed to one side.

The tortoise showed its head carefully. At the moment when it exposed its head, the little poisonous snake bit the tortoise's head like lightning, and the tortoise quickly shrank back into its shell. But a few minutes later, the tortoise died of poisoning.

The python said: Wow! I tried my best not to hurt the tortoise, but you did it easily.

The little viper said, because I know his key.

However, there is still a problem. After the tortoise died, it still stayed in its shell. Both snakes are devouring animals, and they can't get rid of their turtle shells, so they have to leave disgruntled.
