I want to ask about Zhuge Liang's borrowing from the east wind in history

Don't think that he bought it with Daoism on stage. He didn't borrow it. At that time, the weather was occasionally easterly, and Zhuge Liang would observe the sky and know when to start blowing. Like a straw boat borrowing an arrow, he knows the time of fog and has a trick up his sleeve. He knew that when he was sure he would win, Zhou Lang would kill him. He did this to impress Zhou Lang, distract Monroe and others, and buy time for his escape. The third is to save him, because he just said there was an east wind. None of them are copied, and I don't know if they are reasonable. Let's have a look.
