The Earl from the East

[Travel + no system + Western fantasy + lord + multiple female protagonists + conspiracy] Traveling to another world and becoming a gangster? Duke, a modern young man, accidentally fell into the ancient Western continent where swords and roses intertwined, but found that being a civilian was equivalent to a death sentence in a slave society. At the critical moment of life and death, he straightened his clothes and called himself "Earl of the Tang Dynasty". He used advanced technology to improve farming and used outstanding thinking to build his own business empire. When the barbarians' iron hooves carried the sand and dust and headed south, Duke tightened his grip on the tempered steel blade - this was the first weapon he forged using modern iron smelting technology that transcended the times. When the church's holy emblem and the crown's scepter cast intertwined shadows behind him, the cold and charming earl's daughter who was married to him was throwing the secret message into the brazier, and the erudite female scholar was deducing the rise and fall of the empire for thousands of years on the parchment. Caught between royal power and divine power, the wealth accumulated in their hands made them even more jealous. Where should Duke's future go?
