(This is a non-systematic imaginative article, so readers should not read it with caution) Accidentally traveled to the end of the Ming Dynasty, a time of internal and external troubles. Development is the last word, and strength is the panacea for resolving disputes. Overthrow the Ming Dynasty and defeat the Manchu Qing Dynasty and become emperor yourself? No, being an emperor is too tiring and I have no interest at all. I just want to make money, make a lot of money. By the way, the Ming Dynasty was also saved. We also want to make money from Europeans and the whole world. Wherever there is war, there are my clients. Wherever there are people, there are my customers. I just want to regard Greater China as the birthplace of the industrial revolution.
