Datang: Making Explosives at the Beginning Shocked Li Er

In the Tai Chi Hall, Li Shimin was furious, holding a five-meter-long test paper in his hand. "What the hell is this written about!" "What is gunpowder?" "What's cement?" "Chamcheng Dao, what is this? It's nonsense!" Cheng Jin: "Just because you don't know, it doesn't mean he doesn't exist. Three days, just three days and I will open your eyes!" "Okay, I'll give you three days!" Li Shimin was furious: "After three days, if you can't produce anything, I'll behead you in public!" Three days later, a mushroom cloud rose in the palace. Li Shimin was so frightened that he was confused: "This... What is this?" "Gunpowder!" "Quick, Cheng Jin has a great talent, hurry up and appoint him an official!"
