I Opened a Treasure Chest in the Three Kingdoms

Lu Bu, the most powerful general of the Three Kingdoms, was reborn, and he thought he could make a splash. Unexpectedly, the original owner had been beaten by the coalition forces of Cao and Liu and was forced to retreat to Xiapi City. The people inside were unstable, there were large armies outside, and he did not inherit Lu Bu's peerless martial arts. Facing a hellish start, there is no room for waste. This is a rhythm that requires you to kneel down! Fortunately... The protagonist has the Supreme of the Three Kingdoms system with him. By completing system tasks, he can obtain treasure chest rewards such as bronze, silver, and gold. See how the protagonist changes his fate against the odds and becomes the Supreme of the Three Kingdoms step by step!
