Calculate the weather: borrow the east wind

How to calculate the arrow: the arrow of the grass boat

Calculate Lu Su: I can't summarize this. Anyway, every time Zhuge Liang can be sure that Lu Su will find him, it can also be counted that Zhou Yu sent him to find Zhuge Liang.

Counting Zhou Yu: Three Yu

Count Cao Cao: Cao Cao defeated Huarong Road.

I hope it helps you.
