Great Qin Son-in-Law? No, I’m Aiming for the World!

After his soul transmigrates into the Great Qin, he becomes a merchant's son-in-law, bullied by everyone. Wielding modern wisdom as a blade, he uses the arts of a powerful minister to fight his way through deadly political traps, taking lives with every step! He battles the First Emperor, executes Li Si, and turns the whole world into pieces on his board. When the old order collapses, he dons black armor, revolutionizes the realm, and leads the Great Qin's iron hooves across the globe for the first time!
