I Am in the Three Kingdoms, but I Have Awakened to the Upgrade System

A modern otaku traveled to the Three Kingdoms era, became Huangpu Song's grandson Huangpu Yi, and successfully awakened the system. Just when Huangpu Yi was about to put into practice the growth routine of summoning generals and exchanging items that he had been thinking about for many years, he was stunned to find that this was actually an upgrade system. Ah, this... Then I want to go to heaven? Guo Si and Li Jue can't beat them? Come, dig a hole for me, and I will personally bury the remnants of the Yellow Turbans who refused to surrender yesterday. Lu Bu is too strong? It doesn't matter. I'll bring the thieves I just captured yesterday and I'll kill them myself. This novel and its characters are purely fictitious.
