Traveling through time to become the down-and-out proton Ying Zheng in Handan City? Hungry, looked down upon, and possibly beheaded at any time? It doesn't matter, I have two guides: one is called "Historical Records" and the other is called "Five Thousand Years of China". From Proton to First Emperor, I am familiar with this road. But when I really set foot on it, I discovered that what is more complicated than history is the human heart; what is more difficult to tame than unifying the six countries is the times and destiny. Let's see how a modern soul can hold on to ancient authority and write the true story of "unification of the world" between laughter and iron blood.
