Cao Cao, Sun Quan, Liu Bei and Zhuge Liang, the whole joke flew together.

One day, Zhuge Liang, Liu Bei, Sun Quan and Cao Cao were on the same plane. On the way, the plane suddenly broke down, but there were only three parachutes on the plane. So Zhuge Liang came up with an idea: how about asking a mountain man to ask a few questions, holding an umbrella with the right answer, and jumping directly if the answer is wrong? Everybody answer. So Zhuge Liang asked Liu Bei: How many suns are there in the sky? Liu Bei thought it was very simple and answered: one. So I jumped with one on my back. Zhuge Liang asked Sun Quan again: How many moons are there in the sky? Sun Quan answered: One. So Sun Quan also jumped. Zhuge Liang turned to Cao Cao: How many stars are there in the sky? Cao Cao was puzzled and could not answer, so he had to jump directly. Fortunately, he fell into the sea and killed him. Another day, four people were on the plane, and the plane happened to have an accident. There are still only three parachutes on the plane. So I decided to use the old method. Zhuge Liang asked Liu Bei: Who led the famous Hundred Regiments War? Liu Bei replied: General Zhu De. Zhuge Liang nodded and Liu Bei jumped down with an umbrella. Zhuge Liang asked Sun Quan, how many enemies did he kill in this battle? Sun Quan answered: About 30,000-40,000. So Sun Quan also jumped. Zhuge Liang turned to Cao Cao, and Cao Cao thought, I am a military expert and I am secretly proud. Unexpectedly, Zhuge Liang asked, what are their names? With a loud cry of "Ah", Cao Cao jumped directly and fell into the sea again. The third time, four people shared a plane, and the plane had an accident. Cao Cao thought: I Cao Cao must not be humiliated any more, so I opened the cabin and jumped. I didn't know there were three people laughing: Cao Cao, you have been smart and confused all your life, and you can have four parachutes this time! "Wow", Cao Cao died by spraying blood.
