Introduction: I am a refugee from the first year of Zhenguan, and my whole family has only one breath left. The victims were chewing tree bark, and the Turkic cavalry were watching outside, but the system asked me to build toilets and dig smelly ditches first? The aristocratic family called me a pariah, and secretly sharpened their swords to use me as a sacrificial flag. They don't know that in my previous life, I stood at the end of human civilization. I built a blast furnace on the street, made hundreds of steel, and made gunpowder and distilled liquor by hand. The aristocratic family said that my sorcery had deceived the public, so they requested an order to dispatch troops to eradicate my village. On the day when their army was approaching, I silently set up a row of heartless cannons at the entrance of the village. Li Shimin's imperial edict is still on the way, and I am writing a letter of persuasion to surrender to the Turkic Khan - in the name of the Construction Corps. Later, the entire Tang Dynasty's infrastructure standards were changed to Yu.
