Is it that modern people think Zhuge Liang's ability looks like a god, or is it Luo Guanzhong's Romance of the Three Kingdoms? Romance of the Three Kingdoms is nothing more than a folk tale, which was invented by Luo Guanzhong. It is only a novel in essence and has no historical significance at all. If you want to get close to history, read history books.
Take Battle of Red Cliffs as an example, you can see this. It is well known that Zhuge Liang used grass boats to shoot arrows. In fact, the hero of the story is Cao Cao, replaced by Luo. However, it is really Zhou Yu's clever plan to burn Cao Jun. Huang Gai's suggestion has nothing to do with the so-called "if you want to break Tsao Gong, you should attack him with fire". Luo Guanzhong knew to shoot Zhuge Liang's face.
In addition, the empty city plan is just an iron powder fabrication of Zhuge Liang in the Jin Dynasty.
Zhuge Liang is a "Xiao He" and a "Sean", but there is no one in the army of Shu. From this perspective, Zhuge Liang is just a shrewd politician, not a "god".
