This kind of plan does exist. In practical sense, it is a counter-measure, similar to Jiang Gan stealing books in the Three Kingdoms. Moreover, there are many such plans in our real history, such as the battle of crossing the river (similar to the defense plan of the national army and the deployment of the PLA), and many similar plans have been made for these. So, this plan does exist, but it may not be called the death plan.

And poison bee teacher Wang Tianfeng has a historical prototype. He is Wang Tianmu, one of the four donkey kong Scouts, and Wang Tianmu really betrayed the Scout, which caused the whole Scout Shanghai Station to suffer a devastating blow. However, the file finally shows that this is a game arranged by scout boss Dai Li, and Wang Tianmu is just one of the pieces. The so-called mutiny was also inspired by Dai Li and even the top scouts. Isn't this the real death plan? If you are interested, you can search Wang Tianmu. Historically, there are many similar death plans at home and abroad, such as the meat stuffing plan of the allied forces during World War II, which also belongs to this category. Hitler sent false information to the Germans by special means, mistakenly thinking that the allies were only pretending to attack Sicily, but the real goal was Greece, which led to Hitler's wrong withdrawal of Sicily's military forces. But in the end, it turns out that the goal of the allied forces has always been Sicily, which led to the defeat of the Germans. This is the meaning of this plan.
