It Turns Out That the World Lacks Music?

Li Jiaju accidentally traveled to a world where music was extremely scarce, and even pianos and other musical instruments became items that could only be used by nobles. Li Jiaju used his memories before time travel to let the world experience what the Renaissance is. "Two tigers, two tigers..." "Go away, what a stinky stone, does it deserve to be called red yeast?" The corners of Li Jiaju's mouth are hooked up like a dragon king. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
