Traveling Through the Qin Dynasty and Accidentally Killing Liu Bang

I, a modern outstanding young man with three good qualities, had just turned 18 years old and I had a great youth to enjoy. Unexpectedly, I accidentally traveled through time in a car accident and became a local ruffian in the Qin Dynasty, with tattered clothes, rotten straw sandals, disheveled hair, a full beard, and no money. Wen, Tianbeng starts the game, but I didn't expect the time traveler to really have a system. The novel will not deceive me. With its help, Liu Bang was defeated, Xiang Yu was killed, the Huns were destroyed, and all the Japanese pirates were killed. They were pushed all the way, and everyone in Europe surrendered, realizing the true unification of the world, and becoming an emperor for the ages.
