Zhuge Liang's war of words led to Confucianism.
In the early Three Kingdoms period, Zhuge Liang's main contribution was to make Sun and Liu Lianhe resist Cao Cao, and finally they were defeated in Chibi. According to the novel, Zhuge Liang borrowed the east wind and then destroyed Cao Cao's army with fire. The fact is that Battle of Red Cliffs is the result of Zhou Yu's painstaking efforts and has nothing to do with Zhuge Liang.
Zhuge Liang's main contribution should be in the late Three Kingdoms period. After Liu Bei entered Shu and proclaimed himself emperor, Zhuge Liang began to play a role in internal governance.

As we know, Liu Bei's entry into Shu was ruled by a foreign regime, which led to many contradictions, and Zhuge Liang's legal practice greatly eased the problems between locals and foreigners. He adapts to local conditions, conforms to the times, and does not stick to the rules. He formulated and improved laws and policies, so that Liu Bei, who traveled all over the world and finally got a base area, completed the excessive integration of foreigners into Sichuan, which was Zhuge Liang's main contribution.

This is just as Chen Shou, the author of The Three Kingdoms, summed up: "Zhuge Liang is also worried about the country, comforting the people, showing etiquette, appointing people on their merits, surrendering to the power system, being sincere and fair."
This sentence shows Zhuge Liang's achievements in managing internal affairs and is also a great affirmation of Mr. Wolong.
It's just that The Romance of the Three Kingdoms is well known throughout the ages, and it will be misunderstood to interpret its contents as official history.
