Reasoning reason
Because it is up to the doctor to decide which rabbit to use as a drug guide, and the two rabbits are doctors. Therefore, two rabbits killed five rabbits with a knife, which is love killing.
Love killing is not a random guess, because Ertu has a high position, but even so, there is something he can't get, and that is true love. This is the main reason why two rabbits kill five rabbits. Moreover, the five rabbits are honest and should often fight against him at ordinary times, so they have killed their hearts.
Introduction to nursery rhymes
Big rabbit is sick,
Two rabbits, look,
Three rabbits buy medicine,
Four rabbits boil,
Five rabbits died inexplicably,
Six rabbits lift,
Seven rabbits dig holes with their heads stuffy.
Eight rabbits to bury,
A small tombstone in the dark forest,
It's the cold remains of rabbits,
The wailing and shouting are long gone,
The sun climbed out slowly,
Nine rabbits sit on the ground and are sad.
Ten rabbits asked him why.
Nine rabbits said,
Five rabbits, if it never comes back ...
Lift high,
Buried deeply,
Don't let the five rabbits climb out again.
To put it simply: ten rabbits like nine rabbits, while nine rabbits and five rabbits like each other. Ten rabbits are jealous. Ten Rabbit is the closest person to Big Rabbit, and he knows the relationship between other rabbits like the back of his hand (that is, he knows exactly what will happen if Big Rabbit gets sick). Five rabbits are also powerful people in the DPRK, and ten rabbits can't dispose of him casually. So the Ten Rabbits made Big Rabbit sick, and then everything happened as mentioned above ... So, the main thread running through the whole story is the Ten Rabbits. If Er Bunny is the direct murderer, then 10 Bunny is the invisible murderer behind the plot, and it is the invisible operator of the whole murder case.
Let's review: Five Rabbits died miserably, because Two Rabbits were madly jealous of him, so they didn't want him to be a normal man. Besides, the emperor ate the pharmacist's medicine, and he was dissolute. Everyone should know where he was the weakest. The so-called "what to eat and what to make up", in fact, the part where the five rabbits were made into medicine should be ...
10 Rabbit is the closest person to Big Nutbrown hare, and he knows the relationship between other rabbits like the back of his hand (that is, he knows exactly what will happen if Big Nutbrown hare gets sick).
Therefore, the main thread that runs through the whole story is 10 rabbit, which is the end of this story and the main reason of this story, so that this logic is seamless, and the name of the story is one of the 36 strategies: killing people with a knife!
