I Am Really Not Zhuge Wolong in Three Kingdoms

Accidentally traveled through time and was stranded on a deserted island. Zhuge Xun obtained the system and began to survive. A storm transports three strange-looking strangers to the island. "I am Liu Bei!" "I am Guan Yu!" "I am Zhang Fei!" Zhuge Xun: "Stop playing around. Which crew are you actors from? Take me out quickly!" When Zhuge Xun casually took out potatoes and high-yielding rice, Liu Bei was shocked! When Zhuge Xun casually chatted a few words about history, Liu Bei immediately knelt down! Liu Bei: "Sir, is Zhuge Wolong?" Zhuge Xun: "No!" After several inquiries to no avail, Liu Bei took action directly: "Sir, stop pretending. I know you are the real Zhuge Wolong. The one in Longzhong is a fake, right?!" Zhuge Liang: "??? I have lived in seclusion for more than ten years, and the lord I have been waiting for has been cut off?!" Zhuge Liang wants to cry but has no tears!
