I Succeeded in My Rebellion, and Now You're Saying My Grandpa Is Qin Shi Huang?

In the final years of the Great Qin Dynasty, Ying Ziyao transmigrates into the body of a wealthy merchant's grandson in the capital. He shares a surname with the First Emperor, but has absolutely nothing to do with him? This damnable fate leaves Ying Ziyao thoroughly depressed. But never mind. The First Emperor is about to die, and chaos is just around the corner. Why shouldn't Ying Ziyao make a name for himself? So he grabs his adoptive grandfather and persuades him to raise the banner of rebellion. “Grandpa, the First Emperor is about to die. We need to prepare now and build something great!” “Not enough weapons? Come on, I've got a new steelmaking method. We'll arm the rebel army to the teeth!” “Can't beat the Meng family army? No problem. Give everyone a musket and show the Qin army what we're made of!” Ying Ziyao is determined to achieve greatness. He wants to put his grandfather on the throne, then take a turn sitting on the Dragon Throne himself. Who could have guessed that one day he would discover the truth? There is only one family in the world named Ying! It's the family of Ying Zheng! So his surname comes from Ying Zheng's grandson, and his grandfather's surname comes from Ying Zheng too! And Ying Zheng has already conquered the entire world!
