Tang Dynasty: the Prince Consort Descends from Heaven

On the first day of time travel, Zhao Heng was kidnapped as a Turk spy. Facing Li Shimin, he made a shocking statement: "Your Majesty, I come from more than a thousand years later." Li Shimin sneered: "Drag him out and chop him up." Zhao Heng came to his senses out of desperation: "Your nickname is Erlang, your favorite horse is called Teller, and your queen's nickname is..." Li Shimin's expression changed: "... Save him a life." From then on, Zhao Heng started a life of cheating in the Tang Dynasty - fine salt is as white as snow, glass is blinding, gunpowder explodes Turks, and horseshoes make cavalry fly. By the way, he also became happy enemies with Princess Changle. Princess: "Do you dare to marry me?" Zhao Heng: "I refuse..." Li Shimin: "Do you dare to refuse a try?" I thought I was here to be a prince-in-law, but I didn't expect that I was here to be a cow and horse. But it doesn't matter, as long as the technology is hard-core enough, even the emperor of the ages will have to call me "Da Lang"!
