美毁芝加哥的神秘大火在北美五大湖南部一望无垠的平原上，密执安湖南岸的芝加哥城，居住着300多万人口，为美国第二大城。它是世界肉类加工业和农机制造业的中心。谁能料到，它是100多年前的一场大火之后发展起来的，而毁灭芝加哥城的纵火者至今还没有查出来。1871年10月8日， The United States destroyed the mystery of Chicago’s mysterious fire in North America, the vast plains of Hunan, the vast plains, Michigan City, the south shore of the city of Chicago, inhabited by more than 3 million people, the second largest city in the United States. It is the center of the world’s meat processing industry and agricultural machinery manufacturing. Who would have expected that it was developed after a major fire more than 100 years ago, and the arsonists who destroyed the city of Chicago have not been detected yet. October 8, 1871
