Three Kingdoms: I'll Visit My Relatives and Become Cao Cao's First Counselor

In 196 AD, Lu Fang traveled to the Three Kingdoms period and became the grandson of Lu Boshe. In this life, Lu Boshe was not killed by Cao Cao, but died of the plague. The protagonist uses his family letters to visit his relative Cao Cao and seek an official position. Cao Cao didn't see him, but he made friends with a man who called himself Lao Meng. Every time he asked himself about some important national affairs, the safety of the people, or just some questions, "What kind of person do you think Cao Cao is?" "When do you think we should attack Yuan Shao?" "Who do you think can succeed Cao Cao?" Lu Fang was speechless. I am a time traveler bound to the strongest counselor system. Why don't you introduce me to Cao Cao and ask me irrelevant questions every day? Just when the protagonist saw that everything he had said to Lao Meng had been adopted by Wei Guo, he said, "Well, Lao Meng, you took all the credit for me, right?" When Lu Fang wanted to break into Cao Cao's camp alone and ask for an official position, Lao Meng quietly told Lu Fang, "I am Cao Cao!"
