I Am Really Not Zhuge Kongming

I am a gamer and a scumbag. By chance, I traveled through history to the Three Kingdoms era. The most terrible thing is that I became Zhuge Liang. A scumbag forced to play the smartest military advisor in history. During this period, there were many difficulties, and every decision was related to the future. . It makes me feel even more stressed. What worries me most is whether changing history will affect the future. Therefore, I can only rely on my only advantage of historical knowledge to finish the prime minister's legendary life!
