Exotic Hero

There are some old-fashioned routines where the protagonist comes to another world! The difference is: The protagonist Liu Cai does not have a wealth of modern knowledge! There is no advanced technology as the backing for development! Not even a superman with extraordinary force! He is just a gangster living in real society with a hundred brothers. After arriving in the unfamiliar Labol continent, how could he bring his brothers to a good life? How do you live your life? How can you get ahead? How can I... Create your own underground kingdom?
