Your Majesty, I’m Really Not a God Who Descended to Earth

Shen Xuan transmigrated to ancient times. He also acquired the Historical Correction System, which helped the various dynasties of Great Xia set themselves on the right path. And his first stop was Great Qin. You say it was a shame that Great Qin fell after just two generations? You wonder whether Qin or Rome was stronger? It doesn't matter. Shen Xuan will show you the answers through his actions! Years later, however, when Taizong looked at a portrait from the Qin dynasty, he fell into deep thought. In the portrait, Shen Xuan had his arm around the First Emperor, like a pair of brothers. Shen Xuan panicked at the sight. “Your Majesty! Please hear me out. I'm really not a celestial being sent down from heaven!”
